Terahertz Laser for Sensing and Imaging Outperforms Its Predecessors

Terahertz Laser
Terahertz Laser is a high powered laser developed by Massachusetts Institute of Technology for chemical sensing and imaging. The Terahertz laser designed by the researchers of MIT, has three goals which includes high constant power, tight beam pattern and broad electric frequency tuning.

Terahertz Laser to be used by NASA on its 2021 mission to study our Galaxy’s origin


NASA has chosen the Terahertz laser for its 2021 mission to study more about our galaxy’s origin. With the help of a high altitude, balloon based telescope carrying photonic wire lasers, they will detect emission of gases like oxygen, nitrogen and carbon from the interstellar medium, which is the material between the galaxy’s star systems.

The Terahertz laser could also be used for skin and breast cancer imaging, detection of drugs and explosives and many other applications.

The design of the Terahertz Laser


The design of the Terahertz laser is unique which uses pairs of efficient wire lasers and sync their oscillations. On combining the output of the pairs there will be a single, high power beam with minimum beam divergence, which is the angle the beam moves away from its focus over distance. The individual paired lasers can be fine-tuned to obtain improvements in resolution and fidelity in measurements. All these give rise to less noise and higher resolution in order to achieve more cost effective and reliable chemical detection and medical imaging.

In the past, people have made a laser with high beam quality or with high continuous wave power or have done frequency tuning in lasers. But all the designs have one of the factors lacking. Ali Khalatpour, a graduate student in electrical engineering and computer science, who is also the author on the paper describing the Terahertz laser in Nature Photonics says that this is the first time where all three metrics are present in the chip-based Terahertz laser.

NASA has chosen the Terahertz laser for its 2021 mission


NASA will be using the Terahertz laser for its 2021 mission to detect gas emissions from the interstellar medium. By procuring data over a few months, they will get insight into the birth of the star and evolution. They will get more knowledge of the Milky Way and the Large Magellanic Cloud Galaxies which are close by.

NASA selected a new semiconductor based terahertz laser which is suitable for spectroscopic measurement of oxygen concentrations in terahertz radiation. It is a band of electromagnetic spectrum between microwaves and visible light.

Achieving three metrics in chip-based terahertz lasers


Researchers had developed new types of quantum cascade lasers known as photonic wire lasers. These were bidirectional and hence less powerful. This issue was sorted out by placing mirrors within the laser’s body. Since the terahertz radiation is too long, and the terahertz laser is small, it was difficult to fix it within the laser so much so most of the light travels outside the laser’s body. In the laser that NASA selected they developed a design to control how the electromagnetic wave travels along the laser and emit in one direction. They were able to obtain high efficiency and beam quality, but it did not allow for frequency tuning.

To overcome this, the researchers applied the concept of pi-bonding to the lasers, enabling close connections between the wire lasers. This coupling allowed phase locking of two or more wire lasers.
To obtain frequency tuning, they used tiny knobs to alter the current of each wire laser, which changes the refractive index. This change in refractive index together with coupled lasers, gives rise to a continuous frequency shift to the pair’s center frequency.

The researchers are building a system with a high dynamic range of more than 110 decibels which can be used for many applications including skin cancer imaging. Since skin cancer cells absorb terahertz waves more strongly than healthy cells, the terahertz lasers will be able to detect them.



With terahertz lasers having the three performance metrics, they can improve imaging capabilities and can be used in other applications.

5 Things To Do Before Sending Your PCB Design Off For Manufacture

When you finally finish designing your printed circuit board for your product, it can be tempting to just send it off for manufacture right away. Of course, with manufacture comes many risks so you need to make sure that you have created something which has been tested thoroughly before having it mass produced. This is why we have created a list of some things that you should do before sending off your PCB design for manufacture. Keep reading to find out more.

Consider Design Scale

One of the first things that you should do before sending your PCB design off for manufacture is to consider the design scale. You will need to think carefully about whether the cost, the time to layout or the board size is more important to you. Think about the advantages of all of these and choose what is best for you. Never forget about design scale or this could cause problems.

Gather Your Documentation 

Throughout your PCB design process, you should have been gathering documentation that you will send to the manufacturer. Some of the PCB design software packages from providers like Altium come with features to aid this meaning you’ll be able to take advantage of the Manufacturing Outputs Datasheet which will come in handy in the design process. Make sure to check over all of your documentation carefully before sending off your PCB as errors on the documents could slow down the whole project.

Consider Cost Of Component Size

If you are working on a budget in your PCB design process, then you are going to need to think carefully about the cost of the components and what size is best for your budget. Some manufacturers might not be willing to work with your parts if they are too small and this could bring your costs up quite high. Make sure to consider this carefully before you send it off to the manufacturer.

Research Your Parts

Although you should be able to get your hands on most of the parts that you have in your BOM, you should make sure to do some research. Some of the rarer parts will be harder to get your hands on and you might need to make some changes to your design. If the parts don’t come in packages that you are comfortable working with then you might have a problem on your hands.

Consider Thermal Concerns

Our final tip for those who are about to send their PCB design off for manufacture is to consider the thermal concerns. If you have very large parts right next to your smaller parts you might find that you come across some serious problems. When the heat comes into the process, your parts might start to be an issue, and this is not ideal.

If you are finished with your PCB design and you are ready to send it off to be manufactured, you should make sure to take everything that we have discussed into consideration.

Google has Unveiled Flutter 1.0

Google unveiled the Flutter 1.0 at an event at the Science Museum in London, UK. The Product Manager Tim Sneath introduced Flutter 1.0 to the enthusiastic developers.

What is Flutter? 


Flutter 1.0 is a cross-platform portable UI toolkit. It is an app engine that brings software development kit (SDK) out of beta.

Since 2015, it was undergoing various stages of development. Several of the beta versions were out last year and a preview of Flutter saw the release this summer.

It allows developers to build apps that can work on Android and iOS from a single codebase.

Flutter was designed by Google so that there could be a better collaboration and rapid development between the developers and coders. It is powered by Skia 2D graphics engine.

Material Design widgets which would look nice on both, Android and iPhone devices, will be powered by Google’s Dart platform. It will enable compilation to native 32-bit and 64-bit ARM code for Android and iOS. With the ‘stateful hot reload’ feature, you get quick visual results without any need to restart, thus saving time and increasing productivity. According to Google, the development cycles are three times more productive.

Flutter, being an open source, with a BSD-style licence, allows contributions from developers all over, since there are plenty of third-party plug-ins and widgets ready to be tried out.

Ashley Narayanen told Computer Business Review that even though it has the ability to target more than one platform which is not a new concept, the others being Xamarin, Cordova and React Native, it is a product of Google and not a third party component.

The other point to be noted is that Flutter is slated to be the main framework for the next-Gen operating system, Fuschia.

Though the Xamarin framework offers a native experience, there are still problems in cross-platform targeting since a complete 100 percent of the components cannot be used across both the Android and iOS platforms.

It has been designed to support Google’s ‘Material’ design language as well. Since there is heavy use of shadows and other effects, one can use the native hardware graphics acceleration on both the Android and iOS platforms. With the result it is capable of handling such workloads.

Many Big Companies are using Flutter


Big companies like Alibaba, Groupon, Tencent and others are developing and shipping apps with Flutter.

The mobile payment service Square announced two new Flutter SDKs whereby accepting payments for goods and services would become easier with Flutter. It could be done by using a Square payment reader or payments within the mobile app developed on the platform.

Animators 2Dimensions announced the use of ‘Flare’, a tool that enables designers to create animations which could be embedded into a Flutter app and manipulated with code. With Flare, there is no need to design in one app, animate in another and convert everything to a device-specific assets and code.

With Flutter, app design is radically simplified. Google made an announcement that they would be experimenting with running Flutter on the web under the codename, Hummingbird.

Google Introducing Call Screen

Call Screen May Require A Save Option!

Google’s Pixel 3 and 3XL’s feature is heaven send when you don’t want to answer those annoying spam calls that come multiple times in a day. If you don’t want to answer any of those calls, and who does anyway? then send the caller directly to call screen. This new software feature initiated by Google to the Pixel 3and 3XL phones has been one of the most innovative and best feature to come to a phone as yet, not to mention it saves you the immense hassle of getting rid of the robot troll caller.

But is it all great? On the surface yeah! We all know how annoying robot troll callers can be but what happens when you want to save a call or need important information right away?

What is Call Screen? 


A feature that can be found on Google Pixel 3 and 3XL allows the user an option of putting a call through call screen whereby Google Assistant picks up the call and you can monitor the call proceedings in chat form while the call is ongoing.

The moment a person calls and you want to press the call screen option, Google assistant immediately picks up and lets the caller know that they are speaking to an assistant. The caller then has to explain who they are and what they want. While all this is going on you can view the chat form of the dialogue taking place between the caller and Google assistant.

So what’s the Problem with Call Screen then? 


While everything seems to be picture perfect with call screen, it’s just that it does not store the transcript of the message or have an option to send the caller to voicemail.

This can be bad in instances, where you need some important information that the caller has. You can always screenshot the chat screen while the call is taking place, that is if you remember to do so. But if you forget, there is no way to get that specific information back, unless you go to the call log and call the person back.

While none of the chats are stored after the call in call screen, some may actually appreciate the fact their privacy has not been affected.

What Should Google do to improve Call Screen?

To improve the call screen feature which is pretty great now but can be made better, Google can do three things- save the transcripts of the chats to the Pixel 3 or 3XL, give a “send to voicemail” option and lastly have the option to save particular calls. Google says that the first option of saving transcripts of the chats onto phones may be coming soon.

During call screen when the caller knows they are talking to Google assistant, they automatically give their name and certain other details. Many a time, this information comes in handy and you don’t want to necessarily miss out on that info. Hence the need to save transcripts or chat history in call screen.

Discovery of a new Printing Technology Making use of Sound Waves

Printing Technology
Engineers from the University of Harvard have come out with a new printing technology that makes use of sound waves. This is a great revolution in printing where the sound waves control the droplet flow of highly viscous liquids. In other words, the new printing Technology involves a printer which uses sound to print with the help of tiny droplets of highly viscous liquids.

The new printing technology will help in the manufacturing of biopharmaceuticals and bioprinting. Here they use biopolymer and cell-laden solutions which are 100 times denser than water.

According to Jennifer Lewis, a senior author and professor of Biologically Inspired Engineering at Harvard University, the new printing technology that they have created helps printing in a drop-on-demand manner.

In the new Printing Technology, how the liquid can be manipulated with the help of sound waves: 


We see in Inkjet printing which patterns liquid droplets, the liquids are about 10 times more viscous than water. The researchers are far more interested in liquids that are more viscous. In the case of biopharmaceuticals and bioprinting, biopolymer and cell-laden solutions are about 100 times more viscous than water. There are some sugar-based biopolymers which have the same viscosity as honey which is about 25,000 times more viscous than water. Viscosity of fluids is influenced by temperature and composition changes. With the result, controlling the droplet size becomes difficult and hence it is not possible to optimize the printing parameters.

The researchers therefore wanted to develop a new printing technology independent of the viscosity of the fluid. They thus turned their attention to using sound waves. When we consider a liquid under gravitational force, the droplet size is large and the flow of the droplet is difficult to control.

The researchers have thus turned to generating sound waves in order to enhance drop formation. Pressure waves have been used to defy the earth’s gravitational force, as is seen in Acoustic Levitation. These same sound waves are being used by the researchers to assist gravity and the new technology adopted is known as acoustophoretic printing.

The researchers have built a sub-wavelength acoustic resonator that can generate a highly confined acoustic field that can pull a force that is 100 times more than the gravitational force at the tip of the printer nozzle. In this new printing technology, the controlled force then pulls each droplet from the nozzle on attaining a specific size. It is then ejected on the area for printing. If the amplitude of the sound waves is high then the droplet size is small, irrespective of the fluid’s viscosity.

The new Printing Technology can have a wider scope: 


The new printing Technology was carried out on different materials like honey, stem-cell inks, biopolymers, optical resins and liquid metals. It was seen that the sound waves do not travel through the droplet and hence the method was safe to use even in the case of sensitive living cells or proteins. They hope that the new printing technology can help in the manufacture of new biopharmaceuticals, cosmetics and food.

New Molecular Wires to help Shrink Your Devices

Molecular Wires
Since gadgets and the like first came out, scientists all over the world are in a race to shrink their sizes. It is not enough that you hold the device in your hand or fit it into your bag, they just have to get smaller. But smaller is not the only criterian, theses gadgets or gizmos have to perform better and with better battery life. To achieve this aim, scientists have tried making each and every component in the gizmo smaller and one such part is molecular wires.

Scientists at Tokyo institute have developed a new form of wire that not is smaller than their predecessor but is also better at conducting electricity. These new form of molecular wires are filled with organometallic ruthenium which gives it better conducting. The current forms of molecular wires are much different to the ones invented by the scientists up at Tokyo. In the sense, that these new molecular wires get their high conducting power from a different source.

Molecular Wires in Tiny Devices: 


As devices get smaller, their component parts also get smaller, that’s a no brainer. But molecular wires are just the building blocks in such devices and maybe one of the most important yet fundamental of all parts.

By carefully designing these molecules, scientists have tried to make beeter contraptions for us to use.

The New form of Molecular Wires: 


These new form of molecular wires are in the form of a metal- electrode- molecular- metal- electrode junction. This includes a polyene molecule which is an organic chain like molecule.
These new form of molecular wires are based on the engineering of the energy levels of the conducting orbitals in the wire.

Is the new form of Molecular Wires better? 

 

Scientists used scanning tunneling microscopy to understand the level of conductance in these new form of molecular wires. What they found was that these new molecular wires are better than the standard or other fully organic molecular wires.

This brought scientists to explore the origins of the superior conductivity in molecular wires. They found that the properties that gave these molecular wires their high conducting properties came from orbital splitting in the molecular wires.

This orbital splitting brings about changes in original electron orbitals in the atoms of the molecular wires to make a new hybrid orbital. This new form of orbital facilitates electron transfer between mental electrodes and molecular wires.

This finding is rare to see in current MMM junctions.

What gives these Molecular wires their Higher conductance: 


The most important factor that gives these molecular wires their higher conductivity is the narrow gap between the highest and lowest molecular orbitals. The new technique formulated by scientists in making these molecular wires exploits this knowledge in enhancing the molecular wires conductivity.

Using the same MMM junction in these molecular wires along with the extremely narrow gap between the highest and lowest orbitals, scientist have come up with a new form of molecular wires that has unprecedented levels of conductance.

How Technology Has Made Communication Easier and Less Expensive

Remember the good old days when you had to send a handwritten letter in order to communicate with your best friend who lived two counties away? Or better yet, remember when you picked up a landline and could hear someone else's conversation taking place? If you remember the first scenario but not the second, you're a millennial. If you remember neither scenarios, you're Gen Y. If you remember both scenarios, you're likely thankful for technology.

Technology today has made it easier than ever for the world to stay connected. Not only that, it has made it less expensive than ever before. For instance, to place a long distance call on a landline would cost homeowners anywhere from $.05 to $1.40 per minute. "Long distance" in this instance, however, isn't what it means today—it meant the next town over, or anything out of a defined local calling code. For many people, talking with friends, family members, or acquaintances was an expensive endeavor—that is, if they didn't keep their calls short enough.

Today, thanks to advancements in technology such as Skype, cloud calling, and switches (conmutadores for our Spanish readers), individuals can connect with others from towns, cities, states, or even countries over, without fear of racking up a huge bill. Below are just two ways in which technology has made staying in touch so much easier.

Relay a Message in a Matter of Second


Before the advent of vehicles, letters would take approximately 14 days to reach their final destinations. With the advent of vehicles, that timeframe was significantly shortened, and individuals could relay a message in as little as two to three days. From a pioneer's perspective, that's unthinkable; from a modern person's perspective, that's unacceptable. Thanks to platforms such as Facebook, SnapChat, Instagram, and email, people today can communicate back and forth via text within a matter of seconds. Of course, text messaging should not be ignored. Text was one of the first modern modes of communication, and it has changed the communication game forever.

Host Calls Over the Cloud


10 or even five years ago, if you used the term "cloud," most people would assume you were talking about those fluffy white cotton balls in the atmosphere. Today, however, the term "cloud" has taken on a whole new meaning. Cloud simply refers to something hosted on the internet. Oftentimes, that something is storage, but a lesser known use for the cloud is calling.

Cloud calling allows anyone with an internet access to place a phone call, for free. This makes it easy for individuals who don't have great cell service, who don't have access to a cell phone, or who simply want to place a call from their workstation, to communicate with others.

As if that's not benefit enough, cloud-based phone systems allow individuals to meet face-to-face without ever actually meeting in person. Platforms such as Skype and FaceTime use a computer or device's forward-facing camera to allow face-to-face interaction between parties who are in separate rooms, cities, or countries. Again, cloud-based platforms allow individuals to do all this gratis.

Technology has changed the communication game for the better. Thanks to technological advancements, humans can communicate in a matter of seconds and for pennies on the dollar—or, in the case of cloud calling, for free.

Tips for Keeping Your Business and Your Customers Safe Online

GDPR

The internet is a place of adventure and excitement! It allows us to connect with anyone, anywhere in the world, at any time.

It has also made doing business a lot more exciting. Just a few decades ago, businesses were relegated to serving customers in their immediate area. Today, businesses can sell their goods across the globe, making more money than they ever thought possible!

However, for as exciting as the internet is, it also comes with loads of responsibility. That’s especially the case if you’re a business that wants to stay safe online and keep its customers safe online as well.
With these tips, you can confidently build your presence online without worrying about the security of your company or the safety of your clients and customers.

Create a Comprehensive Privacy Policy

In a world of hackers and businesses that sell your information for money, a privacy policy has become a must. A few questions Reciprocity recommends asking yourself include, "Do you even have a written policy for handling, tracking, storing, and sharing the data you collect? Do you have clear steps defined in the process, including how to tag data, so you can easily retrieve it no matter where it goes?"

Based on those answers, you can, "determine which of them your enterprise is in compliance with and where it falls short, and what you must do to reach compliance."

Digging into your privacy policy will help you uncover compliance issues, and at the same time, it will boost user confidence in your brand.

Get Smart About Logins

The wrong logins can make your business susceptible to hackers. That means sensitive company information could be stolen, but it also means your customers’ information can be stolen too.

It’s time to get serious about logins. That means choosing logins that:
  •   Don’t contain recognizable words
  •  Contain numbers
  •  Contain symbols
  •  Have at least 12 characters
It also means being careful about who in the company has access to what information. Only provide access to essential information and lock down the rest so you don’t have to worry about a leak from the inside either.

Be Careful with Ecommerce

There are a lot of great tips out there about how to create a fantastic ecommerce website. By following those tips, you can literally build a customer base that spans the entire globe.

However, it’s ecommerce that can cause the most security problems. After all, people are giving you their personal information for your product or service! That’s why you have to be careful about establishing and maintaining an ecommerce site.

Only ask for information from customers that is absolutely necessary to complete a transaction. Follow ecommerce best practices and consider not storing any payment information to protect yourself and your customers from fraud.

Keep Security Software Current

Malware and viruses are a real threat to your business too. It isn’t just hackers! That’s why it’s important to keep your security software current.

Downloadable programs make this easier than ever, but there are some other things you should do to protect your computer and your database.

Update everything in a timely manner. That includes security software, but it also includes browser and operating system updates. You may also want to consider additional programs, like ad blockers, that can keep you safe from a wide variety of threats.

The best approach to security is definitely one that includes many different techniques and methods to keep both your business and your customers safe.

Educate Yourself on Scammer Techniques

Sometimes, you’re at fault when it comes to compromising the safety of your business or your customers. Don’t be too hard on yourself though. Scammers can be tricky!

It pays to educate yourself on the best ways to protect yourself from online fraud. That includes:
  •  Never clicking on a link from an untrustworthy sender
  •  Double checking email addresses to make sure the sender is who they say they are
  •  Keeping tabs on your social media followers and deleting fake or hacked accounts
When in doubt, it’s always a good policy to throw it out. Falling for a scam could mean losing control of important company information, and it can also mean your customers have to deal with drained bank accounts.

Online safety is about more than just keeping your business safe—it means keeping your customers safe too! With these tips, you can confidently do both so your company remains successful for many years to come.

Atomically Thin Magnetic Device Could Lead to New Memory Technologies

Thin Magnetic Device

Atomically Thin Magnet Device Could Revolutionize Modern Technologies

Atomically thin magnetic devices could pave the way for new technologies in the field of cloud computing and consumer electronics. The modern digital technologies are made of magnetic materials. There has been a breakthrough by a team from the University of Washington in encoding data using magnets which are a few layers of atoms in thickness. This will be a leap forward in cloud computing technology and consumer electronics whereby data storage can be increased and there will be great improvements in energy efficiency.

According to reports that appeared in the ‘Science’ journal, there was a study conducted by researchers wherein they used very thin materials to control the electron flow based on the direction of their spins. The electronic spins are comparable with tiny subatomic magnets. Sheets of chromium tri-iodide (CrI3), a material considered as a 2-D magnetic insulator were used in the materials.

They used four sheets and each sheet was only atoms thick. It created an atomically thin magnetic system that could block electrons based on their spins and at the same time exerted 10 times stronger control than the other methods. This created a possibility of storing data on atomically thin magnets. The team was able to electrically control the magnetic properties of the atomically thin magnet.

The main challenge is to increase data storage and at the same time reduce the operation energy. The team is finding out how the atomically thin magnet could increase memory storage by taking advantage of the electron spins in each individual sheet. The researchers are looking at the possibility of achieving an increase in memory storage and reduction in operation energy. They are looking at ways of engineering atomically thin magnetic memory devices with lesser amount of energy consumption than what is presently achievable.

The working principle behind the atomically thin magnetic device

Two layers of CrI3 were sandwiched between the conducting sheets of graphene. Based on the spin alignment between the CrI3 sheets, there are two possibilities. One is the electrons can flow unimpeded between the graphene sheets or they can be blocked from flowing. These two possibilities could act as bits of the binary code for encoding data. They could act as the bits – zeroes and ones.

The operational units of this type of memory are magnetic tunnel junctions (MTJ) or magnetic gates that can either impede or allow the flow of electrical current depending on the spin alignment in the junction. This magnetic gate helps to figure out the data storage on a small scale.

With four layers of CrI3 in the atomically thin magnet, the researchers discovered the possibility for multi-bit information storage. If we consider two CrI3 layers the spins are either in the same direction or in the opposite direction. This gives rise to two different rates for the electrons to flow through the magnetic gate.

When there are three or four CrI3 layers, there is a possibility of different combinations for the spin alignment between each layer giving rise to multiple, distinct rates for the electrons to flow through the atomically thin magnetic material from from graphene sheet to the next.

This enables the storage devices to have not only two choices but many more choices to store data. Thus the atomically thin magnetic devices that use the CrI3 junctions will be more efficient and will be able to store more data.

Using Evolutionary AutoML to Discover Neural Network Architectures

AutoML

Human Brain – Wide Range of Activities

The human brain has the potential of performing a wide range of activities most of which does not need much effort, for instance in conveying if a visual extract comprises of buildings, or animals. In order to perform this activity the artificial neural networks needs vigilant strategy from professions with several years of complex research, addressing each particular task in discovering what lies in an image, to name it a genetic variant or to assist in diagnosing a disease. One would prefer having an automated system of generating the precise architecture for any particular task. One of the methods of generating the architectures is by way of utilising evolutionary processes.

Old research for neuro-evolution of topologies had laid the foundation which enabled the application of these processes at scale, presently. Several of the groups have been operating on the subject inclusive of OpenAI, Uber Labs, and Sentient Labs together with DeepMind. Google Brain team certainly had been discerning about AutoML too.

Evolution - Scale Function on Construction – Architecture

Besides utilising learning based approaches it was also speculated on the use of computational resources to programmatically evolve image classifiers at exceptional scale.Queries addressed were: `Could we accomplish solutions with minimal expert participation? How good can artificially-evolved neural networks be at present?

The purpose was to enable evolution at scale function on constructing the architecture. The procedure found classifiers similar to hand made models at that point of time, beginning from the simple networks. This was inspiring since several applications needed minimum participation. For instance some would require improved model though could not have the time in being a machine learning professionals.

The next query that came up was,would a combination of hand-made and evolution perform better than any of these approaches. In a recent paper `Regularized Evolution for Image Classifier Architecture Search (2018) participation took place with the provision of sophisticated building blocks together with good initial conditions.

Scaling of Computation – New TPUv2chips – Google

Scaling of computation had been done utilising the new TPUv2chips of Google. With the combination of up-to-date hardware, skilful knowledge together with evolution the result produced state-of-the-art models on well-known benchmarks for classification of images namely CIFAR-10 and ImageNet. In the paper besides evolving the architecture, at the time of exploring the search space of early condition as well as the learning rate schedules, the population trains its networks.

 This consequence is that the development with enhanced hyper parameters producedentirely skilled models. When the experiments tend to begin, no professional input is essential. The second paper `Regularized Evolution for Image Classifier Architecture Search offered effects of applying evolutionary systems to search space. Mutations tend to adapt the cell by erratically reconnecting the inputs or switching the operations.

Though the mutation tends to be simple, the initial conditions are not. The population tends to get modified with models which tend to adapt to the outer stack of cells.However if the cells in such seed model tend to be unsystematic, there will be no beginning from simple model that eventually would make it simpler to obtain excellent models.

The paper has portrayed that evolution can locate state-of-the-art models which could compete or outdo hand-designs.

Researchers Develop Nanoparticle Films for High-Density Data Storage

Nanoparticle Films
High density data storage gets a boost with the development of nanoparticle films

Data generation in this age is quadrupling with each passing day and we are unable to store or manage the mammoth amount of data at our disposal. Therefore finding an alternative which enables us to store data at longer period of time with great stability has become a critical necessity. Now researchers from Northeast Normal University in China has developed new nanoparticle films which are 80 times thinner than the human hair but can easily help in high density data storage. Researchers have asserted that these nanoparticle films can easily archive more than 1000 times worth of data than the traditional DVD on just a 10 by 10 centimeter large piece of film.

Promises usage from wearable device to deep space

It is a remarkable technology and we are likely to see it being used in the wearable devices in the short time. These nanoparticle films can also store the 3D images of the objects or people which can viewed as a 3D hologram with natural realistic and in-depth details later on. These nanoparticle films can be used in the regular devices and the storage medium developed by its usage is also environmentally stable which means used in the outside condition or can even be utilized in the space conditions where harmful radiations are the way of life.

Storing more and more data by taking less and less space

This new kind of nanoparticle films has been designed specifically for the new age holographic data storage. This data storage hasn't found much support or recognition so of today as it makes use of the laser to create as well as read the 3-D holographic recreation of the data present on the nanoparticle films. It is blazing fast with the ability to write as well as read millions of bits at once which makes the holographic data storage way ahead of its traditional counterparts.

The traditional counterpart are namely the optic and magnetic data storage system which happens to record and read just individual bits at a time with is both time consuming and extremely slow when it comes to huge amount of data.

Holographic approach in the high density data storage allows researchers to record information throughout the 3D volume of the entire naoparticle materials. Herein data is not just recorded on the surface but it also researchers to record multiple data or images in the same given area by simply using the light at varied angles and using different colours. Researchers are also working on recoding holographic images on the titania silver films in order to get the similar performance with lesser effort and higher stability.

At the moment researchers are aggressively planning to test the environmental stability of these nanoparticle films in order to ensure quick and safe real life application of the same in the upcoming days. It will certainly help in removing the data storage woes of millions of users worldwide with simple and easier application.

Researchers Demonstrate Existence of New Form of Electronic Matter

Electronic Matter
According to the news that has been published in the journal ‘Nature’, engineers based at the University of Illinois have shown that a new form of electronic matter exists. It is called quadrupole topological insulators (QTI).

The properties exhibited by this electronic matter, QTI could bring about a wide range of possibilities in the computer field. It holds great promise in the manufacturing of low-power, robust computers and various devices, that are all defined at the atomic scale.

The topological insulators (TI) are basically electrical insulators on the inside but are conductors along the boundaries. This unique property exhibited by the topological insulators makes them a special type of electronic matter.

A group of electrons form their own phases within the materials. This can be either in the solid, liquid and gas phase, as is seen in water. They can also form an uncommon phase like a topological insulator.

What is this new phase of Electronic Matter? 


The new form of electronic matter is the Quadrupole Topological Insulator. According to theoretical physics, some of the topological insulators have an electrical property known as quadrupole moment.

As we see in a material, the electrons carry a charge. In the process, the material becomes bipolar, that is it contains the positive as well as the negative charge.

Now, in a higher order class of material, we get a quadrupole which is a coupling of two positive and two negative charges. In crystals, the electrons can arrange themselves in such a way that they can give rise to high-order multipoles besides the usual dipole units. In the case of multipoles, four or eight charges are collectively arranged in a unit. The basic forms of multipoles are the quadrupoles wherein two positive and two negative charges are coupled together in a unit.

An analog of a QTI was shown by the researchers of the University of Illinois. They demonstrated it by using a special material from printed circuit boards.

Each circuit has a square of four identical resonators or devices that can absorb electromagnetic radiation at a particular frequency. The boards were positioned in a grid to form the crystal analog.
Each of these resonators behaves like an atom and the connections between the resonators act as bonds between these atoms.

The system is then subjected to microwave radiation to measure the amount that has been absorbed by each of the resonators. This in turn will indicate the behavior of the electrons in an analogous crystal. If the microwave radiation absorbed by a resonator is more, then there are higher chances of finding an electron on the corresponding atom.

In the above experiment it was inferred that the corners of the connected resonators absorbed the microwave radiation at a specific frequency whereas the rest of the units did not do so. The researchers then separated the bottom row from the grid and on subjecting it to the microwave radiation, it was noticed that the next highest rows showed the topological effects on absorbing the radiation.

They concluded that the edges of a QTI are not conductive unlike that seen in a TI. It was only the corners which are active and they correspond to the four localized point charges that form the quadrupole moment.

On measuring the amount of microwave radiation each of the resonators absorbed in the QTI, it was confirmed that the resonant states was in a particular frequency range and localized in the four corners. This shows the existence of predicted protected states that would be filled up by electrons that would in turn form four corner charges.

With the experiment conducted, scientists are beginning to understand the possibilities of the new electronic matter and its application. As of now, the physicists can predict that the new form of electronic matter exists, but no material has been found to have these properties.

IBM Cimon

IBM gets into the delivery of equipment to International Space station

International Space Station needs a consistent of supply of essential equipment and food supplies from the earth. Earlier Elon Musk’s SpaceX played a vital role in delivering supplies to the ISS but now even IBM is in the same fray. IBM is aiming towards delivering a very unusual eleven pound robot head to the International Space Station using a device called IBM Cimon or the Crew Interactive Mobile Companion.


All you need to know about IBM Cimon

 

IBM Cimon is powered by company's popular supercomputer Watson. But IBM is utilizing it in a different manner which enables to embark on a unique mission to the International Space Station. Earlier IBM has used the Watson technology to run a number of crystal experiments as well as solving the Rubik's Cube. IBM is working closely with a German Astronaut named Alexander Gerst in order to use the IBM Cimon to perform variety of tasks like conducting complex medical experiment just using the on-board camera.

IBM Cimon isn't just every tech piece rather the company wishes to establish it as a reliable companion for the astronaut in the space which can do a number of tasks on its own or with little guidance from the astronauts. With IBM Cimon astronauts will be able to get a number of prescribed tasks done with effortless co-ordination on the space station. Secondly IBM Cimon will also act as a safetyimprovement device by giving out timely warning of any impending failure. It will be smart and intuitive enough to find the failure even before it is shown on the astronauts control boards.

IBM Cimon learns and improves on its own


As IBM Cimon is backed with the AI technology this device can literally act as the first space assistant which will be beneficial for the astronauts working on the International Space Station.The use of technology in IBM Cimon allows it to possess speech, text and other image processing capabilities. Secondly it will be smart enough to retrieve certain specific information and finding when needed to offer valuable insight in time of need. Thirdly astronauts will be able to teach a number of skills to the IBM Cimon individually thereby enhancing it application.

IBM is essentially making use of the Watson speech and vision technologies in order to make CIMON recognize and understand the different voice sample with perfection. Visual Recognition of Watson is employed to understand as well as learn the construction of plans of the Columbus module of the International Space Station.

As IBM Cimon will be deployed at the International Space Station it is necessary that it understand its layout so it can move around with ease and simplicity. Astronauts have even taught him a number of procedures which is ought tobe carried out by him in connection with the on-board experiments. IBM Cimon shows that the science fiction wouldn't be a fiction anymore as we move towards creating intelligent robots to assist astronauts in space.

Metalens: Breakthrough Seen in Artificial Eye and Muscle Technology

Metalens

Metalens the new human eye?

Researchers may have just found a new version of electronic eye that behaves much like a human eye. This flat electronically controlled artificial eye known as a metalens can autocorrect for blurry vision, giving it a host of uses in various industries be it Augmented Reality, Virtual Reality, in optical microscopes and so on.

By taking a cue from the human eye and its functioning, researchers have made an adaptive metalens that can control the main reasons for blurry vision, which are astigmatism, image shift and focus. While the former two is well out of control of the human eye in correcting on its own, the latter can be taken care of by the functioning of the human eye. Therefore metalens even goes beyond what a normal human eye can do.

What is a Metalens? 


Inspired by a human eye, researchers came up with a flat electronic artificial eye come to be known as a metalens. The Metalens can autocorrect for blurry images caused by focus, image shift and astigmatism.

Combining breakthrough tech in artificial muscle technology and meta lens technology, researchers have devised an artificial electronic eye that is a meta lens that can focus on images in real time much like the human eye does. Going even further than the human eye, a metalens can even correct for astigmatism and image shift that the normal human eye cannot do on its own.
Applicability of Metalens Technology:

Because of the feasibility of the project, metalens can be used in a host of applications such as Virtual Reality, Augmented Reality, Optical Microscopes that can work electronically without the need to refocus or adjust, mobile cellphones, cameras and a host of other applications as well.

While being used in these fields, ametalens is capable of auto correcting blurry vision caused by a number of factors simultaneously.

How is a Metalens made?

A metalens focuses light and gets rid of spherical aberrations by using a dense layer of nanostructures which are smaller than a wavelength of light.

Researchers first developed a metalens which was the size of a single piece of glitter. In order to be used for commercial applications the size of a metalens had to be scaled up. Since each metalens has a lot of information pertaining to it, increasing the size of the metalens from 100 microns to a centimeter sized lens, increases the information relating to it by more than 10,000 times the original metalens. This leads to a file size of gigabytes or even tetrabytes of information pertaining to the design of a metalens.

In order to reduce the size of the file, researchers came up with an algorithm that is commonly used in fabricating integrated circuits. In making a metalens for commercial purposes would require the use of two industries, the semi-conductor industry that makes computer chips and the lens manufacturing industry.

Right now researchers have no plans in selling the intellectual rights of the metalens tech and are exploring avenues to bring the metalens to the manufacturing belt.

NASA Developing 3D Printable Tools to Help Analyse Biological Samples without Sending Them Back to Earth

NASA builds up 3D printable apparatus to help evaluate biological samples without transporting them back to our planet

To make possible astronauts on the ship the International Space Station (ISS) to study biological samples without transferring them back to our planet, NASA scientists, together with an of Indian scientist, are budding 3D printable apparatus that can hold liquids such as blood biological samples with no spill out into micro-gravity.

To understand, how to have an effect on team physical condition, how to formulate an enduring role to Mars furthermore afar, NASA told on 8 February. The innovative NASA’s mission, known as Omics in Space, plans to build up expertise to cram "omics" - in microbiology that are imperative to the health of humans. Omics comprises of exploration hooked on genome, microbiomes as well as proteomes.

NASA has by now deliberated omics by way of attempts such as the Microbial trailing 1 research that check up microbial multiplicity lying on the space station. However there is no method to route biological samples lying on the station, thus they enclose to be propel down to globe. It may possibly be months between the moment biological samples are taken as well as an examination is done, told Kasthuri Venkateswaran of NASA's (JPL) in Pasadena, California, and chief researcher meant for the Omics in Space mission.

He is a former pupil of Annamalai University in Tamil Nadu, told: This mission intends to widen an programmed structure meant for learn molecular biology by means of least team intercession.

This researcher proclaimed that this is one of the major achievements in microgravity. Astronauts amass a range of biological samples, takes account of their own saliva as well as blood, and microbes washed down from the hedges of the ISS. These biological samples could subsequently be jumble through water. Exclusive of the suitable apparatus, biological samples can dribble, glide or else structure air bubbles that could conciliate consequences.

Two years ago, NASA obtains a huge leap through progressive DNA hooked on space meant for the initial time. Astronauts make use of a small, hand-held succession utensil known as the MinION, founded by Oxford Nanopore Technologies. It is a corporation having its head office at Oxford, England.

NASA told the Space mission tactics to put up this sensation by means of budding a programmed DNA / RNA extractor that may put in order biological samples intended for a MinION apparatus. A significant component of this extractor is a 3D printable synthetic sealed unit required to haul out nucleic acids from the biological samples intended for the Minion progression.

Camilla Urbaniak, a Postdoctoral investigator on JPL in addition to co-investigator on Omics in Space, told this has been checked on our Planet. "We are obtaining what is on our planet to study DNA along with uniting the entire rung hooked on an programmed method," Urbaniak told. "What is innovative is a single stop store that could haul out and route the entire of these biological samples," Urbaniak said.

The Next Generation of Cameras Might see Behind Walls




Single Pixel Camera/Multi-Sensor Imaging/Quantum Technology

 

Users are very much taken up with the camera technology, which has given an enhanced look to the images clicked. However these technological achievements have more in store for the users. Single-pixel cameras, multi-sensor imaging together with quantum technologies would bring about great achievements in the way we tend to take images.

The updated camera exploration has been moving away from increasing the number of mega-pixels to merging camera data with computational processing. It is a radical new approach wherein the incoming data may not seem like an image. It tends to be an image after a sequence of computational steps which involves complex mathematics together with modelling on how light tends to travel through the scene or the camera.

The extra layer of computational processing tends to eliminate the chains of conservative imaging systems and there may be an instance where we may not need camera in the conservative sense any longer. On the contrary we would utilise light detectors which few years back would never have been considered for imaging.

 However, they would be capable of performing incredible results like viewing through fog, inside the human body as well as behind the walls.

Illuminations Spots/Patterns

 

The single pixel camera is one of the examples that depend on a simple source.The usual cameras tend to utilise plenty of pixels – tiny sensor features in order to capture a scene which is probably illuminated by an individual source.

However one can also manage thing in a different manner, capturing information from several light sources with an individual pixel. To achieve this one would need a controlled light source such as a simple data projector which tends to illuminate the scene a single spot at a time or with a sequence of various patterns.

For every individual illumination spot or pattern one can then measure the quantity of light reflected thereby adding all together in creating the ultimate image. Evidently the drawback of taking a photo in this way is that one will have to send plenty of illumination spots or pattern to obtain an image – one that would take only one snapshot with a regular camera.

However this type of imaging would enable in creating otherwise impossible camera, for instance that which tends to work at wavelengths of light beyond the visible spectrum, where good detectors cannot be made into cameras.

Quantum Entanglement 

 

These types of camera could be utilised in taking images through fog or thick snowfall. They could also imitate the eyes of some animals and mechanically increase the resolution of an image based on what is portrayed. There is also a possibility of capturing images from light particles which have not interacted with object needed to be photographed.

This would have the benefit of the idea of `quantum entanglement’ which two particles can be connected in a way meaning that whatever tends to occur to one can occur to the other even though they are apart at a long distance.

 Single pixel imaging is considered as one of the simplest innovation in future camera technology and depends on the traditional concept of what forms an image. Presently we are observing a surge of interest for methods wherein lot of information is utilised though out-dated techniques tend to gather only a small portion of it.

It is here that multi-sensor approaches involving a number of detectors pointing at the same scene could be utilised. One ground-breaking example of this was the Hubble telescope that produced images made from a mixture of several different images taken at various wavelengths.

Photon & Quantum Imaging


However, one can now purchase commercial version of this type of technology like the Lytro camera that tends to accumulate information regarding light intensity and direction on the similar sensor producing images, which could be progressed after the image has been taken. The next generation camera will possibly seem like the Light L16 camera featuring ground-breaking technology based on over 10 various sensors.

Their data are connected through a computer with a provision of 50Mb, refocus able and re-zoomable, professional-quality image. The camera tends to appear like a very thrilling Picasso interpretation of a crazy cellphone camera. Researchers have been working hard on the issue of seeing through fog, beyond walls as well as imaging deep within the human body and brain. All these techniques depend on linking images with models explaining how light tends to travel through or around various substances.

Another remarking method which has been achieving ground is based on artificial intelligence to `learn’ in recognising objects from the data and these methods have been inspired by learning process in the human brain which probably likely to play a major role in the forthcoming imaging system.

Individual photon and quantum imaging technologies have been developing to the extent that they can take image with extremely low light levels as well as videos with exceptionally fast speed attaining a trillion frames per second. This is adequate to capture images of light travelling across a scene.

Can Neural Networks Learn to Ride a bike?

Neural Networks
For some riding a bike is easy while for others it seems to be a very difficult task that they have to learn at any cost mostly because- the vast majority already know how to ride bikes and no one wants to be left out. But how easy is it for two yes you read right two neurons comprising a neural network to ride a bike?

Two neurons or two nodes forming a digital neural network to be accurate has learnt to ride a bike and that with no external information or programming to guide it. Researchers that study thinking have used neural networks to simulate models of how a person actually thinks- how thinking works, how it is made and how it responds to the external world.

What is neural networks? 


Neural networks are clusters of neurons that pass on information to one and another by simply strengthening and weakening the connections between them. Don’t be alarmed, these are not actual neurons but simulated nodes or model neurons on a neural network in a computer and not a body.

In a huge step towards artificial intelligence, neural networks can understand a problem and even respond to it without any prior programming about how to solve a certain issue.

Researchers have now used neural networks to learn to ride a bike in a simulated setting on a computer without any before- hand programming to do so. They have found that a neural network comprising of only two model neurons has proved to be successful in riding a bike.

Neural network and riding a bike: 

At the testing stage researchers used an algorithm or program, a human and of course the two neuron neural network to learn to pilot the bike giving all the same rules or instructions- controlling the speed of the bike, it’s leaning to one side or the other, the angle of the handlebars and so forth.

The researcher first tested the algorithm in riding a bike using “what if” programming- what move will keep the bike straight, what move will increase the speed of the bike?

But the algorithm was found to be unsuccessful in learning to ride a bike , it could not do two things at once and tried weird means to reach various goals such as increasing speed it would swoop from side to side to do so. As a conclusion, researchers have found that an algorithm would not have the ability to predict future outcomes as compared to neural networks and therefore would be unsuccessful in solving a particular problem.

The second round of testing involved humans where a human had to learn to ride a bike using only the keyboard. After a few tries, humans were also found to be able to ride a simulated bike.

After the human round of testing, it was time for the neural network. Based on experiences and information given by the people who tried the simulated bike, researchers built a neural network. The neural network assessed the environment the bike was in and how to maneuver in that environment- in which direction should the bike lean and how fast should its speed be. At the end of testing the neural network was found to be successful in learning to ride a bike.

In the neural network, the two neurons comprising the neural network passed on information to one another while one assessed the environment and passed on information to the other, the other neuron in the neural network actually controlled the bike.

The Signs Your Child Might Have Screen Addition, Revealed

Children Engaged in Devices – Screen Addiction

With the progress in technology it is not surprising to see children engaged in deviceswhich have turnedthem into screen addiction. Though the approach of making them to start at an early age has been criticised by paediatric experts and adolescent researchers, several of the apps made available for download for children below five years of age in the Apple app store has shown that many parents as well as app developers have been ignoring the warnings with regards to the devices.

This exposure to screens for children comprising of video games, televisions, computers and tablets could be the reason for the addition trend which has been increasing – screen addiction. While this possibility has been considered by parents in the past by asking `how much screen time is too much? It seems that they had phrased the query wrongly.

As per a latest research published in the journal Psychology of Popular Media Culture, how children utilise the devices not on how much time they tend to spend on them, seems the strongest predictor of emotional or social issue lined with screen addiction’. Actually it does not really matter if a child tends to spend an hour or five, gazing at a screen, but would not suggest five hours duration.

An All-Consuming Activity

According to the new study there is more to it than the number of hours spent with the screen. What really matters whether usage of screen tends to cause issues in the other areas of life or it has become an all-consuming activity.

Now the query lies in how precisely could one tell if the child is addicted to screens. One needs to identify the warning signs like – should the screen time interfere with the daily activities, tends to cause conflict for the child or in the family or seems to be the only activity which brings some happiness to the child.

these gestures are displayed by the child, it could be essential to take action since screen addiction is connected to issues related to relationships, emotion and conduct. However considering it from the positive side, it could be most likely alright to keep them entertained with games on iPad for some time.

The television has been replaced by tablets and phone in soothing the children and keeping them busy. For instance, it has been revealed that one out of three kids tend to utilise gadgets much before they can even speak.

Kids utilising these devices at their tender age could have a substantial effect on the mental health of these toddlers.

Technology Addiction – Influence Behaviour/Sleeping Pattern


Dr Richard Graham, London-based Consultant Adolescent Psychiatrist and Clinical Psychologist Dr Jay Watts have stated that technology addiction could have an influence on the behaviour and sleeping pattern of a child. Five signs had been highlighted in an interview with MailOnline stating that one should observe if the child seems to be hooked.

 Moreover they had also emphasized on the importance of taking a digital detox in order to resolve the obsession. Dr Graham from the Capio Nightingale Hospital which is a mental health hospital located in central London had commented that when people tend to feel an uncomfortable sense of withdrawal when they are not online, is a known fact that the relationship with technology is not handled in a proper manner.

Dr Watts added that parents presently tend to struggle with understanding how crucial social media is to the present generation, the modern day playground is virtual. He added that when electronic devices began to have more importance over behaviour than anyone else or thing and when children seemed to get upset when they were deprived of the technology, it is at that point of time that one needs to begin changing things.

In the case of children the main issue is about the way they tend to get addicted to technology and the way they feel when using it.

Unhealthy Independence 

Those kids who tend to portray any indications of severe distress and agitation when deprived of the technology could be considered as unhealthy dependency. It could be somewhat a condition similar to a drug user and this unhealthy dependency could mean that the child gets agitated when they are deprived on the use of technology.

Dr Graham clarifies that the addiction could be apparent itself in other behaviour pattern. The influence of technology could affect the sleeping pattern of the child; interfere with meal times together with eating habits making the youngster to act up during play time. Dr Graham further stated that addicted children could also tend to be secretive as well as defensive regarding their devices and the usage of them and also debate with parents on a regular basis.

Moreover, children addicted to technology could also refrain or ignore real-life activities, refusing to go to locations where they would not be in a position to use their devices like the cinema.Dr Watts mentioned that it is quite guaranteed that parents are under the misconception that their kid has been spending much time on smartphone or online.

Restrict Time Spent on Usage of Technology 


The main concern is to talk to other parents at school or to observe if a child is more preoccupied than the others. If there seems to be a real difference, one needs to speak to the child regarding cybersafety but also study what could be on the mind of the child which could be addictive within and how this addiction could be helpful in avoiding in the real world.

 It seems essential to restrict the children on the time spend on the usage of technology in order to prevent the formation of unhealthy dependence according to Dr Graham. Techniques comprises of ensuring prolonged periods wherein the youngsters are absorbed on the `real world’ and play time with the other kids.

Forming a determined routine time allowance could be an excellent place to begin with. It could also be essential to ensure that adults switch off their phone or keep it on silent mode while having meals and while spending quality time with family and friends since examples given by the parents could be fruitful and meaningful.

Samsung Unveils “The Wall,” the World’s First Modular MicroLED 146-inch TV

The Wall
One of the products that would stop you in your tracks this time around in the CES is Samsung’s The Wall TV. This has merely nothing to do with its 146 inch size but also it’s amazing quality of images which is bound to stop anyone and draw their attention.

The Wall’s rich colors, insanely bright pictures and sharp images puts any other Television out there as a mere screen with nothing much to offer.

The Wall and its Micro Led Tech:

For some you see one Television you feel like you’ve seen them all. I mean what more can a TV offer? Well Samsung has proved that a TV can do much more with it’s “The Wall”. The Wall’s micro led feature, as Samsung like to call this new form of tech, is something that separates this TV from the rest.

Micro led or in other words self –emissive LCD is a tech where 3840 by 2160 liquid crystals all generate their own color and light. What separates the Wall from the rest is that there are no longer pixels that have to share a light emitting from an external backlight.

Ok you might say that OLED can already do this but with the Wall and micro led tech, the bright pixels and dark pixels go together without any bleed and what’s more is that the colors are even more brighter and vibrant with the micro LED tech than what any OLED TV would be able to achieve.

“Modular Design” in The Wall:

Coming to the screen itself in The Wall, is not actually a single screen but rows and rows of pixel blocks that come together in a way that can be used in screens of any size maybe even bigger than 146 inches.

Planning to buy the Wall for your Home? You might want to look at this:

One of the main concerns when looking at the wall at close range is that you would notice the seams in the pixel blocks when a darker picture is shown. While from far there is not much you can see by way of the seams, the closer and darker the picture gets you can see through the seams in the so called modular design. Brighter imagery again covers up those seams.

Another issue that comes to mind when looking at the The Wall screen is that it’s lesser than smooth finish slightly reflects light from surrounding areas.

The next issue is the price, having a screen with micro led tech and a whole other lot going on is not going to come cheap to anyone’s bank account even if you do get the wall in a smaller size.

Quality of Pictures on The Wall:

It goes without saying, but in such a huge TV with micro led tech where each pixel gives off their own color and with insanely bright imagery, the picture quality on the Wall is better than good.

In spite of its largeness the Wall affords pretty sharp imagery, it makes you wonder what it can do with 8K resolution than the 4K it comes with.

Targeting Myopia through Next Gen Contact Lenses

New age contact lenses to bring respite to the people suffering from myopia

Millions of people are suffering from variety of eye disease one such popular eye deteriorating condition is myopia. But a team of researchers from Brisbane has successful developed the next gen contact lenses which can help in changing the loss of eye sight in the long run. This new contact lens has been developed with the partnership between the world’s largest contact lens manufacturer Johnson & Johnson Vision and Queensland University of Technology’s professor Michael Collins. This helped in boosting the research being conducted by the professor into myopia and helps in enhancing the contact lens design to the next level.

A collaboration to last for two decades

This enhanced contact lens is a result of the 20 year collaboration between these two in which 12 years will be given towards supporting the university’s research program for the global myopia epidemic. Professor Collins has stated that this collaboration will help them in understanding the development as well as the progression of myopia. It is worth noting that there are more than two billion are suffering from myopia globally and it affects almost 4 million people in Australia.

Currently the team of researchers are working towards finding better strategies to slow and stop this disease before finding a perfect way to prevent it. In upcoming next few years they will be focusing on developing new optical designs specifically for the next gen contact lenses which has the potential to slow down the eye growth.

What is myopia and how it affects you?

Myopia or nearsightedness is one of the most common ‘refractive error’ for the eye. It is caused by the eyes growing too long eventually resulting in reproduction of blurred images. In this condition people have difficulty reading and seeing distant objects clearly but they are able to see the close up things well enough without any issues.

People suffering myopia will have huge difficulty in reading signs too far away like billboards, road signs but reading books will be a simple task for them and in some cases using computer wouldn’t require spectacles.

Saving the human eyes with next gen contact lens

Professor Collins has asserted that his research isn’t just focused towards reducing and preventing the rise of myopia but towards helping people in seeing better and clearer than ever before. It should be noted that the people suffering from myopia area more likely to develop other eye problems as they get older. They are at the risk of contracting eyes problems like retinal degenerations which can eventually lead to the partial blindness.

Therefore it becomes vital to slow down the myopia progression right at the younger age. He even states that the two main causes of the myopia are genetic risk and environmental causes. People who happen to do a lot of near work like reading, spending time indoors, or looking at the computer screens longer duration are likely to develop myopia.

This next gen contact lens will help the people suffering from myopia to start their way on the road to slow progression rather than sharing the risk of partial blindness in later years.
