NASA Tests Next Generation Passenger Planes with Fat Test Dummies

Dummies
NASA/FAA – Guidelines for New Airplane Crash-Worthiness

NASA in association with FAA have come together for a petrifying drop testwhich will be making way for guidelines for new airplane crash-worthiness. The scientists have strapped ten dummies of different body formsinto model of a regional jet fuselage dropping itt straight down at a speed of 30 feet per second.

 Moreover they also involved baggage in the cargo and though human would probably not withstand severe injuries in the situation, the bags got ragged right through the floor. The test had been piloted at Langley Research Centre of NASA in Virginia as part of the effort of Federal Aviation Administration – FAA, in order to consider the reliability of new planes which contains non-metallic parts.

Martin Annett, crash test engineer of NASA had informed that they were working with the FAA to update the necessities essential for the testing of next generation airframe concepts, particularly those which could comprise of composite materials. The scientist had examined what could have occurred to the structure of an airplane and the humans on board, should an accident take place. In order to do this, they released the fuselage cut-out from a height of 14 feet.

Collecting Data on Regional Jet-Sized Aircraft

Joseph Pellettiere, chief scientist and technical advisor for crash dynamics for FAA informed that they have been looking on collecting data on regional jet-sized aircraft and its performance especially metallic planes.

He further added that this way they could improve a regular baseline data which could be utilised in comparing with new and novel designs which could use changed materials. They then equipped ten dummies with transducers for testing the loads as well as strains on their bodies buckling them into conventional airplane seats.

The dummies had been designed to imitate actual travellers representing a variety of body categories. As per NASA, eight of the dummies were said to be 50th percentile males that had been exhibited after the average man in height, mass and proportion.

One is said to be a 95th percentile male and is designed to be heavier as well as taller than 95% of men while the tenth is a 5th percentile female of around five feet tall and 110 pounds. Together with the setting of the dummies with transducers, the engineers had also connected instrumentation in the model cross section of the fuselage also which enabled them to view how it held up under the effect.

Data Recorder to Measure What Occurred During Crash

Moreover they also placed baggage into the mix. Annett commented that one thing which was unusual in the test was that they had included baggage in the cargo hold which was an actual unclaimed baggage from an unclaimed baggage centre in Alabama.

They wanted to see how the luggage would interact with the subfloor separating it from the dummies. Justin Littell, test engineer of NASA also commented that they had put a data recorder in one of the bags in order to measure what occurred to it during the crash.

The engineers had dropped the cabin onto two feet in one trial. With the use of a technique known as full field photogrammetry, the camera was capable of capturing distinct deformations of the craft, created on black dots that had been painted around the tube.

Recording 500 frames per second, the camera followed each of the dots showing the changes. Though, the dummies received a `good jolt’, the researchers informed that they probably would have made it through all right.

Building Cities of the Future Now

Future city

Cities Upgraded for Future

New cities are being built around the world and the ones that have been lived in for years are being upgraded for the future. It is partially the cause of over-crowding as well as pollution and partly due to an ever-connected world that makes sense to peg entire cities up to the network.

A smarter city would mean that utilises data on traffic for easing congestion or one which focuses in linking services for provision of improved information for the citizens. For several it could be about making cities much greener as well as efficient.

Some of the technology companies like IBM and Cisco tend to see smart cities as large business opportunity though in conjunction with the schemes being advertised by technology companies seems to be more grass root project that targets to empower citizens enabling them a say in how the city would be viewed.

For several of them, Songdo in South Korea is the poster boy of the smart city and the $35bn project situated on reclaimed land towards the Yellow Sea has been generally considered to be a model for smart cities across the world when it had begun in 2005.

Information System – Universal City of U-city

Songdo’s information systems, also known as a universal city of U-city, seemed to be connected to each other. Moreover it had led critics to label it as a `city in a box’, a showcase for technology though not essentially the perfect city for people. Sensors seem to be on everything in Songdo, for instance, escalators tend to move only when someone is on them.

A telepresence system built in like a dishwasher is present in every home. Besides permitting users to control the heating system and locks, it also provides video conferencing and is designed to deliver education, government services together with health care. Offices as well as schools also tend to be linked to the network. The digital organizer behind Songdo is said to be Cisco supplying the network-based technologies that are needed.

Masdar, United Arab Emirates

Masdar which is meant as `source’ in Arabic is said to be a city which tends to stand in the centre of the desert of Abu Dhabi in the United Arab Emirates and is created to be one of the most ecological on the earth. Having solar power station at its core and wind farms giving energy for the same it tends to be carbon free. Besides this, it is also a hub for clean-tech companies.

From water right up to garbage, everything in the city is said to be measured and monitored, thus being a source of information. The city is said to be constructed on raised platform enabling easy access for the `digital plumbers’ to the system of progressive technologies which seem to run it. It is also pedestrian friendly and totally car free.

The city is said to be carrying out trial with a network of electric driverless podcars. The personal rapid transit – PRT would be running 6m beneath the street level through the city. The architects’ firm of Norman Foster who had designed various striking buildings inclusive of The City Hall in London have designed the buildings in the city.

It is expected that around 40,000 people would ultimately reside in the city with around 50,000 shuttling there daily.

Rio De Janeiro, Brazil 

City mayor Eduardo Paes had commissioned IBM in creating a city-wide operation centre connecting all the 30 agencies of the city from transport to emergency facilities. This shows that the officials from all over the city could join forces in handling the movement of traffic together with the public conveyance system as well as ensure the power and the water supplies function proficiently.

Synchronized response can be taken in case of a crisis, like collapsing building. Shutting down of transport system, emergency services can be organised together with gas supplies to be cut off while citizen can be updated of substitute routes through Twitter.

The research team of IBM have developed a sophisticated weather forecasting system wherein it takes data from the river basin, land surveys, the historical rainfall logs of the municipality and radar feeds to forecast rain together with the probable flash floods.

It has also begun appraising the effect of weather occurrence on other city conditions like city traffic or power outages. Several citizen-centric apps have been laid by the centre with updates on weather and traffic.

Barcelona, Spain

Last year, Manel Sanroma, chief information officer of Barcelona city council had made a daring statement that the cities of the future could be more powerful than nation states. He had stressed at smart city conference around the world the need of having a strong mayor who would be willing to take control in drawing up blueprint for this type of a city.

Barcelona is considered to be leading and tends to have some remarkable projects which are being rolled out. It has developed well-organized bus routes, modernized rubbish collection utilising sensors as well as introduced smart street lights. The development of a city operating system bringing all systems together in one location is also organized.

 Mr Sanroma had informed BBC that contrasting to Rio no central control room will be there. Presently the biggest projects under development would be to present contactless payments all over the transportation services of the city.

 Besides this, Mr Sanroma also intends collaborating with the other cities. With this it has set up the City Protocol Society with the intention of joining up cities all over the world with businesses, universities together with the other organisations in developing standards for technology platform which would operate in any city.

London, England

Several areas of London dating back to Roman eras seems to be an apparent choice as a future city though there seems to be numerous projects that are presently being developed. On a £24m prize awarded by the Technology Strategy Board in creating a future city it had lost out to Glasgow, though it remained a testing ground for smart technologies.

London has been chosen as an incubator by IBM for testing the algorithms which could power the cities of the future and has been partnering with Imperial College and University College London on various projects, inclusive of a network of sensors in monitoring air quality, water supply and the traffic flow.

Biased Bots: Human Prejudices Sneak into Artificial Intelligence Systems

Bot

Biased robots are here with human prejudices seeping their AI

Most of the AI experts believed that the artificial intelligence will offer objectively rational and logical thinking for the robots and systems in future. But a new study has is showing a darker path for AI wherein the machines are acting reflection so human and the AI is prejudiced with the human notions.

It has been found when the common machine learning programs are trained online with the ordinary human language then they are likely to acquire the cultural biases and this can get embedded right into the patterns of their wording. The ranges of these biases are quite erratic from the preference to certain lower to having some objectionable view about the race or gender.

Security experts has stated that it is extremely critical and necessary to address the rise of biases in the machine learning at the earliest as it can seriously impact their reasoning and decision making in future. In upcoming days we will be turning to the computers for processing a number of things ranging from the natural language translation for communication to making online text searches as well as image categorization.
Fair and just

Arvind Narayanan, an assistant professor of computer science at the Center for Information Technology (CITP) at Princeton has stated that the artificial intelligence should remain impartial to the human prejudices in order to offer better result and judgment making skills. He asserted that fairness and bias present in the machine learning has to be taken seriously as our modern will depend on it in near future.

We might soon be finding ourselves in the center of such situation wherein modern artificial intelligence system will be frontrunner is perpetuating the historical patterns of bias within the system without even us realizing it. If such events comes in the future then it will be completely socially unacceptable and we will still remain good old times rather than moving forward.

An objectionable example of bias seeping into AI

Just a few years ago in 2004, a study was conducted by Marianne Bertrand from the University of Chicago and Senhil Mullainatahan from Harward University. These economists conducted a test wherein they sent out about 5000 identical resumes to over 1300 job advertisements.

They only change the name of the applicants’ names which happened to be either the traditional European American or the African American and the results they received were astonishing. It was found that the European American candidates are 50 percent more likely to get an interview than the African American candidates. Another Princeton study has shown that the set o African American comes more unpleasant associations than the European American sets when it is run through automated system run by the artificial intelligence based systems.

Therefore it has become a necessity to distance the AI from the biases and prevent the cultural stereotypes from further perpetuation into the mathematics based instruction of the machine learning programs. It should be taken as the task of the coders to ensure that machines in future reflect the better angles of the human nature.

Metal as Fuel? These Canadian Scientists are Working to Make it Happen

Can we turn metal into fuel? Canadian scientists are just doing it.

The fuel as we known petroleum and gas will be over in next two decades and we have very little time come up with an alternative. So as per the mainstream technology news some of the Canadian scientists have found of turning the metal into fuel for vehicles in near future.

The researchers from the McGill University have been aggressively studying the combustion capabilities of the metal that also for over a decade. An experiment conducted by them last week in the space has helped in bringing a new twist to their hope of turning metal into fuel.

How this study has helped the scientists?

The technology news has affirmed that the reason behind conducting the experiment in space has the scientists in understanding the way practices react in weightlessness state. Using metal as a fuel is still a farfetched and unusual concept which seems to be an exclusive matter of science fiction but still it can be turned into reality. One of the researchers present in team named Andre Higgins has been studying and working on the concept of turning metal into fuel over two decades.

Collectively they had found that turning metal in powder can help in creating fuel which can be fed to the burner. This fuel will be highly efficient and it will help in releasing more energy and heat per litre of iron power than what is achieved today with a liter of gas.

Quite interestingly the residue in form of iron oxide can again be collected using a vacuum to act as the fuel again. Higgins proudly states this theory as the closed loop system which has higher efficiency than the bio fuel as well as the modern day fuels used in the vehicles.

Saving the planet with green fuel

Metal fuel will not be a ‘green’ fuel and the threat to the Mother Nature and global climate changes will be aggravated if we bring the metal fuel in daily usage. Technology news further shed light onto how researchers will be employing a noble way of recycling the metal fuel with closed-loop system.

These researchers have studied the metal fuels for over a decade which has helped in understanding how it can be brought into fruition for the benefit not the smaller vehicles like cars but also the large vehicles like ships and trains.

A state like Canada which has abundant of metals will certainly see the economic benefits of the shipping metal fuel to other countries. Countries suffering from acute air pollution like China will benefit from the truly closed loop system of the metal fuel.

The biggest benefit of the metal fuel is that it works in closed system wherein the materials will go around and around without causing any harm to the environment. Technology news also brought a revelation that metal fuels isn’t a new thing as NASA has already been using about 16 percent Aluminum powder for its space shuttle’s rocket boosters for quite some time.

Graphene Based sieve Turns Seawater into Drinking Water

Graphene

Graphene Based Sieves Makes Seawater Fit For Drinking

It is an unaltered fact that Sea Water is not fit for drinking because of the excess Sodium content in it, but science is developing at a very fast pace and in this 21st century the stalwarts of science and technology have innovated a new technique through which they can separate salt from the sea water and will make them fit for drinking. We cannot drink sea water because of the taste, simultaneously it leadsto several other health problems like high blood pressure and many more.

Our planet Earth is known as the blue planet because it has approximately 71% of water out of which only 3 % of the water is non-saline and hence fit for consuming. Due to this situation, there are people in this world who do not get optimum amount of water to drink and there are many who even die due to the scarcity of drinking water. If the researchers can reduce the percentage of unfit water by making it fit to drink, then that would be a very big gift to mankind.

A team of researchers based in UK have developed a sieve based on Graphene that can remove salt from the sea water and will make it fit for drinking. A team from the University of Manchester had confirmed a fact in 2004 that graphene consists of carbon atoms which are layered singly and are organized in a lattice in the form of a hexagone, due to which this tool is sure to provide promising results with the help of extraordinary properties, which includes unusual strength in the tensile and a high conductor of electricity that ensures this as one of the most potent material to grant assured measures in the past.

The scientists have also declared that it is quite difficult to manufacture such single layered Graphene with the existing technologies. The production cost is also very high and that needs to be supported. The deposition of chemical vapor method won’t be much feasible to support the innovation from all ends. Rather, a very onymous scientist has confirmed that oxides that are to be used in the Graphene can be produced only via a simple method of oxidation in the lab.

Though, he orated it to be simple, but the process is lengthy. This is undoubtedly a very big step to abolish the problems cropping up due to scarcity of drinking water, but the underlying measures are such that cannot be averted and for this, the technique of Graphene is still at stake. Manufacturing of single layered Graphene is not much feasible, instead we can replace it that with oxide Graphene, which will give the same result with less cost of production.

Some problematic zones have been discovered when it comes to Graphene of single layer and these uncomfort zones can be avoided if Graphene of oxide are used in its place. So, in this era using of oxides of Graphene will be much suitable to avoid unnecessary expansions.

Google Uses Neural Networks to Translate Without Transcribing

Google Makes Use of the Neural Networks for Translating without Even Transcribing

Google is actively working towards enhancing its translation abilities to a whole new level where it can be helpful and promptest in every manner. Google eagerly wants to help the mankind in communicating with people in different language by translating the speech rather than the text language. Almost all the translation tools focuses on translating the text rather than text and Google understand the amount of good work it can bring with it.

The machine translation will actually work by translating the speech into the text then that text is translated in another language. In case the machine gets any kind of error while recording the speech then it will result in error prone language translation which will fail to serve the purpose which it is intended to do. This is where Google is working at.

The Google Brain


Google has deployed a large number of researchers at the Google Brain where they are making use of the deep learning research facility for better results. Researchers have started making use of the neural networks which can help in skipping transcription while translating any given speech at a faster pace with higher level of accuracy.

Researchers has spent huge amount of time which counts into hundreds of hours in training the system with Spanish to improve its translation skills into the English language. The system present at the Google at first went to analyze the waveform of the Spanish audio in order to learn who he different parts of the language tend to correspond with the words in the written English language. Later on this system was entrusted with the task of translating the speech and its was do so with great accuracy and precision through making use of the neural layers.

The capability of this system


A researcher from the University of Montreal who wasn’t a part of this research has stated that the capability of the Google Brain is mind-blowing. It has the ability to find the patterns of the correspondence between the various waveforms. These waveforms happen to be present in the source language as well as the written text. Over the time where learning phase is initiated The Google Brain has the ability to bring one of the best English translations of the Spanish speech.

The quality of translated of the speech is evaluated using the BLEU which helps in understanding how good machine based translations are when compared to the professional human.

The future application of this system


Google developed system will be of great use for translating the speeches in such languages which is usually done by very few people. It can play a vital role during international disaster relief wherein teams can make use of a robust translation system in order to communicate with people who speak different language. An incident can help in imploring its advantages this system as in 2010’s Haiti earthquake the relief team had a hard time in conversing with the people speaking Haitian Creole.

Triboelectric Nanogenerators Boost Mass Spectrometry Performance

Triboelectric Nanogenerators

Scientists Successfully Boost the Mass Spectrometry Performance by Using Tribolectric Nanogenrators


The most basic problem which surfaces in the entire consumer electronics device is the power consumption. We are actively looking for such kind of power source which doesn’t put a hole in our pocket and helps in getting performance out of the device. Researchers have come with a solution by developing the triboelectric nanogenerators (TENG) which will help in converting the mechanical energy from the environment to electricity. And this electricity will be more than enough to power some of the small devices which include the sensors and consumer electronics products.

The team behind this remarkable technology


This technology has been developed by researchers at the Georgia Institute of Technology which can bring a trend of replacing the traditional power supplies with the TENG device for charging. Though in this case the TENG devices will be used of charging the molecules in the spectrometers and the research has shown that it take the sensitivity of it to an unimaginable level which is good in every way. Scientists have conducted few experiments on the smaller samples in order to understand the full extent of the applications of the TENG technology.

During their research it was found that this technology requires further study the TENG offers unique aspects in its output which has a remarkable high voltage as well as controlled current. This means that the TENG can help in making incredible improvements in the ionization process and later on increased voltage speed can be easily applied to the instrument without even damaging it. This research has already been published in the journal Nature Nanotechnology and quite incidentally this research has been supported by the Natural Science Foundation as well as Department of Energy and NASA astrology Program. Researchers has been modest about their astonishing technological discovery based on the nanogenerators by stating that it is quite new and it is being used in a very controlled manner in order to charge the molecules.

The remarkable finding of the research


Researchers have made use of this technology in the electrospray ionization and plasma discharge ionization wherein they have been able to generate singular polarity as well as alternating polarity of ion pulses. Researchers have successfully measured the voltage level present in the mass spec ionizer to be between the 6000 to 8000 volts. It is a great achievement given the fact that the standard iconizer presently in use can only operate at less than 1500 volts.

The future application of the TENG technology


Researchers have retrofitted the tech technology to existing mass spectrometers and this has been done in the lab with great success. Their research has already been published in some of the journals and researchers are hopeful that more number of people starting making use of the TENG technology in not just the mass spectrometry but even other areas. This nanogenerators based technology will certainly help in getting more power for our daily use devices without spending huge amount of time and money.

Why Your Smartphone's Fingerprint Scanner is not as Secure as You Might Think

Fingerprint
Master Fingerprint – Less Secure 

Researchers who had developed `master fingerprints’ with the capability of tricking the sensors, are of the belief that smartphone fingerprint scanners tend to be less secure then led to believe. They were capable of bypassing fingerprint readers that had been utilised in unlocking phones, log-in to apps and in making payments, utilising fake fingerprints developed by using patterns located across several real prints.

 This discovery from New York University and Michigan State University gave rise to query regarding security of the popular utilised technology. The researchers were capable of creating a set of `master prints which could trick a scanner up to 65% of the time.

Fingerprint scanners are considered to be more secured than depending on passcodes in unlocking smartphones. According to Apple the Touch ID scanner utilised on the iPhone tends to have only a one in 50,000 chance of matching with somebody’s finger.

Though the researcher state that they had tested only their discoveries in computer simulation instead of real smartphones, they cautioned that the technology creating artificial physical fingerprints had been refining quickly.

Adequate Resemblance Between Various Prints

Since in present days the fingerprint readers on smartphones seem to be comparatively small, they usually tend to scan various areas of a fingerprint making sure that just one press of a finger or thumb could effectively trigger the sensor.

 Since several users tend to register numerous fingerprints on a device and there are often dozens of various incomplete prints registered on a phone, only one of these incomplete scans could be a match for the sensor in unlocking a phone. According to Nasir Memom of NYU, one of the authors of the study that had been published in IEEE Transactions on Information Forensics &Security had commented that there is a greater opportunity of falsely matching a partial print than a full one and most devices tend to depend only on partials for the purpose of identification.

In spite of the human fingerprints being comparatively exclusive, researchers have stated that they had discovered adequate resemblances between various prints in creating synthetic master prints which could effectively replicate several fingerprints of the users.

Hosted Other Authentication Systems 

Since the phones seem to typically permit several attempts before deactivating the fingerprint scanner and needs a passcode, Mr. Memon had stated that one could create a glove with five different fingerprints which would get into almost half of iPhone before the five attempts permitted, tend to expire.

Irrespective of the well-known trust in fingerprint scanners, some of the phone manufacturers had hosted other authentication systems. The new Galaxy S8 phone of Samsung is said to have an iris scanner together with facial recognition though the latter is shown to have been fooled by images. Moreover, smartphone passcodes have also portrayed to be susceptible to cracking.

There seems to be a one in 10,000 chance of guessing a four-figure passcode though researchers from Newcastle University have shown that the motion sensors in a phone could disclose the numeric codes by identifying how a phone tends to move when certain areas of the screen are pressed.

Japanese researchers had earlier cautioned that posing with peace signs in images could be adequate for hackers in copying your fingerprints and then unlock a fingerprint secured phone.

Researchers Print Promising Two-Dimensional Transistors

Transistors

Researchers just printed two dimensional transistors successfully

If you are wondering what transistors then please note it is essentially a semiconductor devices which helping amplifying and switching the electronic signals or electric power as a whole. It plays a vital in almost all the electronics products which are available in the market and without it you can’t even think of devices performing the way they are. Some of the researchers from AMBER and Trinity College in Dublin have successfully created printed transistors that consist of only two dimensional nanomaterials. The best thing about this innovation is that no one has done it before and the 2d materials used in comes loaded promising electronic properties which is extremely low cost in nature.
This research does have some of the incredible application potential which can’t be explained to its fullest. For example in future the food packaging industry can make use of it bring a digital countdown which will alert the users about the health of the food and placing it on wine bottle can help in showing whether wine is kept at the optimum temperature or not. Their finding has already been published in the Science magazine April issue.

 

The team behind this technology


Using the standard printing technique of combining the grapheme nanosheets which includes the electrodes with two other nanomaterials namely boron nitride and tungsten diselenide. The two most important parts of the transistors is called the channel and separator and researchers has been able to print it on a nanosheet thereby coming up with a working transistor.

The team of researchers consisted of Trinity College professors namely Jonathan Coleman and Georg Duesberg. Coleman has shed light on the future possibility of creating or combining together highly complex device by conducting, semiconducting as well as insulating the 2D nanomaterials. But during their research they simply focused on printing the transistors which can work as electric switches into the modern computing with ease and grace. 

New method indulge in testing without even touching

Earlier the chemical vapor deposition were used to develop the two dimensional transistors. Using this particular the transistors were great at performance but the method itself was quite expensive.

While the printable electronics brings a new way of printing components which are mostly based on the carbon based molecules at extremely low cost and get an amazing performance out of it at the same time. It is worth noting that carbon based molecules does have its own share instability and performance limitations but it is still better than the chemical vapor deposition.

A single nanosheet can do much better

Researchers has made use of many different nanosheets of completely varying size in order to get best combination available for the printing their transistors. When the printing process was initiated researchers simply deposited the nanosheets over one another in random fashion and it was found that the conductivity present within the nanosheets was just good for the job.

So the next job for the researchers is to come with a single nanosheet which will help in printing such 2D structures which offers better performance than the current one.

Controlling Turtle Motion with Human Thought

Turtle Motion
About nine years ago we saw the flick which showed humans controlling the body of an alien. Today we have that technology though it is in the initial but has huge potential to grow by leap and bounds in the upcoming years. Leaving the realm of science fiction aside scientists has long been working on developing a system called ‘brain computer interfaces’ or BCI. This particular technology is designed to allow humans to read and use the thought in order to control the machines and one of its prime examples are the humanoid robots.

Now the researchers at Korea Advanced Institute of Science and Technology (KAIST) had successfully developed a highly sophisticated human turtle interaction system. This system allows the signals emerging from the human brain to produce desirable effect on the movement of the turtle.

How this technology works?

If you are wondering how human are able to control the turtle movements simply with their thought then here is complete process. Human operator has to wear a head mounted display which is commonly refereed as HMD. HMD IS combined with the BCI which helps in immersing the human operator right into the turtle environment. On other hand the turtle in question is equipped with a cyborg system which consists of a camera, Wi-Fi receiver along with a control module as well as a battery. All of this is mounted on the upper shell of the turtle. A black semi-cylinder with a slit is also placed on the shell which helps in forming a true simulation device.

A camera is mounted on the turtle which is received by a human operator. Using these real time video images the human operator has to be deciding where he wants the turtle to move about. Human operator is required to provide all the commands which affects the motion of the turtle using a wearble BCI system which effectively makes use of the electroencephalography (EEG) signals.

Currently the BCI system is designed to take commands only in the three metal states of left, right and idle. Now when the human operator tends to make the choice either left or right that commands happens to activate the turtle simulation device which is connected through a Wi-Fi. This particular process invokes a natural instinct in the turtle to move towards the light and thereby it changes the direction.

Future applications of this technology

This research has clearly demonstrated how the human thought can be utilized in developing animal guiding scheme for turtles. This technology in future can be easily integrated into positioning system and can certainly help in augmented and virtual reality techniques.

On other hand this can be helpful in enabling a wide range of application which might devices form the military reconnaissance and surveillance. But for these to happen it might take another decade to make the technology human proof, robust and highly reliable so that it can distinguish from the raw and concentre commands originating from the human mind.

New Electron Microscope Sees More Than an Image

EMPAD
In the field of material science, electron microscope has lots of application as an effective device. It is usually known to all that this tool helps in viewing at an image. However, with the new enhancement done few days ago, this microscope has gained much more power. And it has been confirmed recently by some physicists at Cornell. The overall system is named as Electron Microscope Pixel Array Detector. It produces image along with some important data on the present electrons, which develop that image.

To give a clear idea about the microscope, Professor David Muller has said that it is possible to identify the tilts, polarity, rotations and magnetic or electric fields.

Manufacturer of the new microscope-

CTL department of Cornell University has accredited the innovation of new microscope to a prominent manufacturer, FEI. According to FEI, the design may be commercialized fully on the present year. In a periodical (Microscopy and Microanalysis) in 2016, the researchers have clarified the work in detail.

In another standard microscope, STEM, the researchers have observed that few electrons could be captured with the help of a specimen. The scanning is done from side to side to generate images. There is a detector at the base, and it interprets how the electrons are varying in their intensity.

EMPAD is intended for the replacement of a standard detecting system, and it is designed with specific pixels, which are sensitive to electrons. Every one hundred and fifty microns square are attached to a circuit, which warns signals with enough effectiveness in understanding signals. This technology is comparable to what you may find in contemporary camera. The major intention is the detection of angles or directions, where the electrons come out. Every electron usually does not strike at the same pixel.

Microscope with prompt working ability-

EMPAD has remarkable sensitivity and speed along with extensive intensities, tracked by it. It also detects each of the electrons and beams that contain almost millions of electrons. To explicate the phenomenon, Muller has commented that it is just like the act of capturing image of sunset, which displays surface details and everything about the shadows.

The advancement that has been done to the device is really unique and increases the excitements of scientists. Collection of all electrons that are in scattered condition develops the sensitive feature of the device. Moreover, it is also reduces the risk of damage and any negative effect on the living sample. EMPAD has power to track the frame of image within shortest time, and it identifies several electrons for every pixel and frame. In fact, it is multiple speedier than that of any traditional electron microscope.

Thus, the new microscope has brought a revolution in the domain of science. The scientists are now competent at examining the internal part of the cells. The research process has been backed up by Department of Energy in the United States and Cornell. STEM adaptation has also received support from Kavli center.

Innovative Software Convert Wi Fi Data into Energy Savings

UBC
The advancement of technology had begun since the arrival of human kind of Earth’s sphere. From the invention of knifes and spears to the creation of computers and tablets, man has managed to come a long way. It is a known fact that this technological advancement has been exceptionally brilliant in the past two centuries. Every day scientists around the world are striving to create something newer that is not only mind boggling but will also be useful to mankind.

High quality air with reduced energy consumption 

Recently in the University of British Columbia in Canada, a group of dedicated engineers have derived a way by which they could use Wi-Fi to establish number of building residents. By determining the number, they can easily adjust the ventilation through which they would be able to save energy without compromising on the air quality. Stefan Storey who holds a PhD in environmental studies and resource management and masters in mechanical engineering from UBC is leading the project. He remarked that thousands of tablets, laptops, and Smartphone are connected everyday to Wi-Fi through UBC. The Bridge Software incognito calculates the total number of Wi-Fi connected devices in every room. This anonymously calculated number is then passed on to the head building control system of UBC, which then regulates airflow through the buildings, in real time.

Based on this resident count, the control system can manage the airflow, ramping it for a crowded lecture, or bringing it down in other times. Storey collaborated with UBC for testing the effectiveness of this new technology at one of the busiest places, Irving K Barber Learning Centre, which is attended by thousands of staffs and students. It not only resulted in increased occupant comfort and goof air quality but also reduced energy expenditure by five perfect in 12 months.

Increased thermal comfort at a reduced rate 


UBC’s managing director, David Woodson remarked that this system can save over $100,000 in energy costs every year and would also assist the university in reducing greenhouse gas emission. UBC is considering this system to be the future of managing and better handling of energy consumption. The test conducted at the learning centre was highly successful and seeing the results of this ordeal, UBC is all set to install the technology in 8 to 10 more buildings within 5 months. Woodson also stated that this software uses Wi-Fi network, to reduce the disruption and lower the costs while offering thermal comfort and providing good air quality. He also stated that UBC Wi-Fi user’s private information is completely secured and protected as per the rules of Canadian privacy legislation.

Storey believes that this project emphasizes the prospective advantages of using Wi-Fi network to create smart buildings. With the support from UBC he also co founded Sensible Building Science, a company that helps staff entrepreneurs, faculty, alumni and students to lead their way through, from a basic idea to the market. Storey’s patent innovation is being set up at campuses around B.C. UBC is extremely happy about the success of this project and is thus is planning to expand their system to 10 more campuses.

‘Machine Folk’ Music Shows the Creative Side of Artificial Intelligence

Magenta
Folk music is seen a direct link which connects us to our past and helping in cementing the cultural bond. When it comes to Artificial Intelligence it doesn’t possess any cultural heritage, bond or traditions but can we help Artificial Intelligence in building those attributes which defines the human intelligence at some levels. Over the years AI has grown by leap and bounds as it has been able to defeat the brightest human minds at Chess and even demonstrated breath-taking wordplay skills but can it create music or show us the creative side.

Artificial Intelligence on the rise

Researchers are trying to unlock the creative side of the Artificial Intelligence for quite some time. In 2016 a AI has been able to produce a piece of musical theatre which was premiered in the London. The effort is given towards broadening the boundaries of the creative research through new evolved AI techniques and utilizing the larger collection of the data. The Artificial Intelligence written musical piece has been a result of a thorough analysis of hundreds of other successful musicals.

Some of the prominent Artificial Intelligence project which aims towards bringing art and music out of the AI includes Sony’s Flow Machines, Google’s Magenta project and some projects under the British startup called Judedeck.

During the current study researchers has made use of the state of the art Artificial Intelligence techniques in order to educate Ai about the musical practice in the Celtic folk tradition. Traditional folk music was reduced into the form of music notation using ABC. In this method the music is denoted using the text characters as a rough guide for the musicians. Researchers have been successful in training the Artificial Intelligence for using as many as 23,000 ABC transcription of the folk music. This particular feat of transcription this amount of folk music was made possible with the active contribution of the people on the ‘the session.org’. During recent workshop researchers has asked the folk musician musicians to perform some of the songs composed by the machines.

The culmination of the artificial compositions and the human melodies

This particular Artificial Intelligence is trained to look at a single ABC symbol and predict what will come next and this helps in generating new tunes which appears to be like original compositions due to the use of existing patterns and structures. So far researchers have generated as many as 100,000 new folk tunes using Ai which is a remarkable feat in itself.

The structure of the folk music composed by the AI has two repeated part of similar eight-bar length and they complement each other quite musically. Secondly AI had also shown a great ability of repeating and varying the musical patterns which has always been the key characteristic of the Celtic music. AI has been able to understand as well learn all the rules set for the Celtic folk song compositions on its own though carefully analysing the patterns in the fed data within a very short time.

Nanoscopic Golden Springs Could Unravel Twisted Molecules

chirality
Molecular vibration is one of the known phenomena in the world of physics. Twisting of molecules is usually observed, while the present atoms of any molecule have periodic motion. In fact, many of the molecules are found to get twisted in a variety of ways. On the basis of their pattern of twisting, they are present in the right or left handed position. Such type of twisting is known as chirality. Recently, some scientists have determined that twisted molecules may be discovered with the help of nanoscopic golden colored springs.

Scientists from the University of Bath have collected gold spring-like coils in their experiment. They are more than five thousand times thinner, in compared to our hair strands. Another component, used by these researchers is the laser, which has allowed them to identify some twisted molecules. All these trials will perhaps bring about an improvement in the design of pharmaceutical matter, nanorobotics and telecommunications. Thus, the coils assist in knowing much data on chiral molecules. However, it is important to have a good idea on chirality and how it alters the behavior of molecules in any place, including our own body.

Chirality- What it is about?

The term, chirality has been extracted from a specific Greek word, which is related to a chiral object. Any system or object is considered as chiral, while it is distinguished from some mirror or reflective image. Chiral molecules consist of a carbon-based atom along with 4 non-identical components.

With the use of laser system, the researchers are able to work on all chiral molecules. This light becomes twisted at the time of travelling. However, their research turns out to be much tricky, while the molecular amount is much small. At this point, the tiny golden springs are much useful. Their design allows the lights to become twisted. It may also adjust to molecules in a better way. Thus, it becomes quite simple to make out the microscopic amounts.

Enhancement of pharmaceuticals through the use of nanoscopic springs-

There are some springs, which are much smaller in size, and the researchers have analyzed their effectiveness. They want to know whether these springs are able to increase the interactions of chiral particles and light. The research is based on the method for converting color. This process is called as the Second Harmonic Generation.

If a spring performs better, more amounts of red colored lights are transformed into the blue ones. From the experiment, the researchers have understood that there’re high potentials in their springs. However, the expected performance depends on the angle towards which they are directed. The system works as kaleidoscope, which involves deformation. The scientists want to reduce this distortion. And this is achievable only with the optimization of springs or in other words, chiral nanostructures.

A very close observation may lead to a development of purity and design of many pharmaceuticals. According to a member of the scientists’ team, it also helps in controlling motion of miniaturize elements in the future.

How to Protecting Bulk Power Systems from Hackers

Grid
Consistency Measure of Electricity Grid – Escalating

Consistency measures of electricity grid have been escalating to new norm since it tends to include physical security together with cyber-security. Fears to any of them could trigger instability resulting to blackouts as well as economic losses.

Several tend to take it for granted of turning on the light. Though in reality, the energy drawn from the electrical grid in brightening homes, freeze food as well as watch TV is said to be a part of a complex together with a widespread system. Comprehending the susceptibilities of the system and the dependability is a vital step in improving its security.

Fresh research headed by scientists from Michigan Technological University explored in the so-called scenarios wherein the hackers tend to exploit the security flaws implementing a disturbing plan of cyber-attacks. Recently the Journal IEEE Transactions on Smart Grid had published their work. Chee-Wooi Ten, lead author, an associate professor of electrical and computer engineering at Michigan Tech stated that the fundamental problem was an opening between physical equipment and intangible software.

 Improvements in smart grid technology like smart meters in homes, management systems for the purpose of distributed energy resources such as wind together with solar production with instrumentation system in power plants, control centres or substations, creates improvements in monitoring as well as access for hackers.

Convenience/Cost Reduction Streamlines Process

Ten had commented that `ten years back, cyber security did not exist and the same was not spoken about and was not an issue. He jokes that people presumed that he was crazy for suggesting the possibility of power grid hacking. He further added that now with events such as in Ukraine last year together with malware like Stuxnet, hackers could plan a cyber attack which could result in larger power outages, people would begin clutching the severity of the issue.

 He further pointed that the hackers focus on specific areas of the control network of power infrastructure and targeted on the devices which tends to control it. Mechanized systems are inclined to control most of the grid from generation in the transmission for usage.

According to Ten, the convenience as well as the cost reduction of automation streamlines the process though without solid security means, it could also make the system susceptible. The interconnectivity off the grid could also result in cascading impacts leading to blackouts, equipment failure and is landing with the areas isolated and cut off from the maid power grid.

Connections/Asses Flaws Utilising Framework

Ten together with his colleagues arrived at connections and assess flaws utilising framework which would regularly assess the block of a power grid as well as its interconnection with their adjoining grids. With the use of quantitative systems in arranging cyber security protection would ensure power grids are operated in a much more secured and safe manner.

Ten also mentioned that it is like measuring blood pressure. He added that one tends to know that their health is at risk since it monitors systolic and diastolic numbers and hence one would work out more or eat healthier. The grid requires established metrics for health also; a number to gauge if one is ready for this security challenge. After gaining an understanding of the weaknesses of the system, it tends to get a lot easier to be strategic and shoreline security risks.

Tens says that in the future, improving regulations with particulars to match actual infrastructure requirements, providing cybersecurity insurance could be beneficial.

Using a Smartphone to Screen for Male Infertility

male fertility test
Male fertility tests are not as simple and easy to perform as the female counterparts but latest innovation made by some researchers is all set to change the game. Most of the at home male fertility tests allows users to just check upon sperm count but it leaves a wide range of other characteristics which also effects the fertility. One of the major important characteristics usually left aside in the so called in-home male fertility tests includes sperm motility which signifies how much energetic are the sperm cell while they move around.

Researchers behind the automated male fertility testing system

The researchers at the Brigham & Women’ Hospital and Massachusetts General Hospital had successfully developed a completely automated system which can effectively help in performing certain male fertility tests. This particular system is remarkable in accurately measuring the concentration of the sperm as well their motility ration by simply using a smartphone. It also requires some of the snap-on components which are quite cheap in nature.

The functioning of the automated system is quite simple wherein the users are required to place the semen sample in a disposable chamber of the snap-on component. The snap-on component is designed with precision and care and doesn’t’ looks odd at all rather it appears like a usual smartphone case. There is a disposable microchip placed in the component and the light source for effectively measuring the part of sample is the smartphones camera. The smartphone camera helps in illuminating the semen sample while sensing equipment placed in the component does the rest of the work.

A special app is required to be installed on the smartphone which in later stage makes use of the image and helps in carefully evaluating the number as well as activity of the sperm cells in the sample. However this isn’t the first of its kind male fertility testing system as there is already a similar technology called YO sperm test system which happens to be sold directly to the consumers.

How this technology works? 

Researchers have made use of as many as 350 clinical sperm specimens to analyse the results and improvise the technology with each iteration. They had made use of unwashed and processed liquefied semen in order to conduct tests. The sample were kept at less than 5-s which ensured lower processing time and helped in getting accurate results with about `98% accuracy. Under the World Health Organisation the test were conducted to ensure its integrity as well as the efficiency of the technology for global usage in the upcoming days.

Their research has also shed light to the fact that by simply integrating few microfluids along with the optical sensing accessories in the modern advanced consumer electronics smartphone can help in developing the remote semen testing equipment without much hassle. Therefore they opted for bringing the amalgamation of the technology on the smartphone which can be easily access by millions worldwide and an app has been developed to provide quick and accurate fertility test results right from the sample within shortest amount of time.

Heated Pavement Technology Tested at Des Moines International Airport

 Heated Pavement
We are living in future or future is dawning upon the humankind. The line is blur and the amount of scientific, technology advancement we are experiencing it will become highly difficult to pinpoint the moment we will step into the future. A team of researchers from the Iowa State University have been successful in deploying the fully functional electrically conductive concrete pavement installed on an America airport. The lead researcher going by the name Halil Ceylan has to simply run an app on his smartphone in order to begin the successful testing on the full scale heated pavement installed at Des Moines International Airport.

Winter season is round the corner the technology implemented by the Ceylan team will help in turning on heated pavement system which will allow snow and ice to melt away. All this is done through an app and it can be seen in real time due to its video capability.

How much it costs?

Most of the people are amazed by the technology and are hooked on learning about the cost incurred in developing it. Ceylan has clarified that the success of the heated pavement slabs has shown that benefits are far greater than the cost. Researchers have carefully calculated the number at the operating cost of just 19 cents per square meters which is unbelievably cheaper.

How the testing slabs were made?

The test slabs designed for the installation at the airport are made up of 1percent of the carbon fiber along with a special mix of the cement, rocks and sand. The use of carbon fiber in the heated pavement technology allows concrete to conduct electricity which ultimately helps in creating heat.

A team member has prepared hundreds of concrete samples in order to come up with the right combination of comprehensive strength, electrical conductivity, tensile strength and workability required for its success. The test slabs are wired with varied kind of sensors which includes strain gauges, temperature probes, humidity sensors as well as it has two surveillance camera mounted near it. These test slabs are powered by the hangar’s power supply which helps in its smooth functioning.

Why testing on an airport?

The reason which prompted Des Moines Airport for testing heated pavement because it’s a part of Federal Aviation Administration sustainability program. In a bid to boost the sustainability and a partnership was established way back in 2012 which brought together a number of credible researchers from the Purdue University as well as other core members from Iowa State. This brings together a number of FAA’s centres of excellence along with the federal government, universities and industry in an established one-of-a-kind cost-sharing research partnership.

This program is currently about $2.2 million for Iowa State to bring about a full scale demonstration of unique airfield d pavements as well as heated pavements for future usage. Earlier a prototype of the heated pavement was successfully placed at the campus lab which showed promising results and feasibility to integrate for the large scale studies.

Intel Launches Optane Memory M.2 Cache SSDs For Consumer Market

Intel
Intel finally unveiled its first Optane product called SSD DC P4800X enterprise drive just a week ago and today it has brought the Optane Memory product which is targeted for the consumers. This product is essentially a low-capacity M.2 NVMe SSD which can only be used as a cache drive in the systems for simple tasks and performance boost.

How does Intel Optane Memory SSD works?

Intel has simply launched two variant of the Optane Memory SSD which makes use of either one or two single die packages of the 3D XPoint which happens to be the non-volatile memory. And this product will be made available only in the 16 GB and 32 GB models. Without going into the fine technical details of the Optane Memory let’s focus on the performance which Intel is proclaiming to be selling point of these device. The Optane Memory drives are of very low capacity which means they can’t be used like the traditional SSDs. The best part about these new drives is that it is designed to be used specifically with the caching capability of its Rapid Storage Technology. Intel has made this technology available way back in 2011 with the Smart Response Technology.

Therefore the Optane Memory is better suited for the 3D Point memory performance which brings a definite flexibility advantage usually missed in the flash memory. Secondly the Optane Memory comes with the NVMe remapping feature which has become a staple feature in the Intel’s Skylake generation 100-series chipsets. Thirdly the Optane Memory caching capability is only limited to the Windows 10 64 bit and that also for the boot volume which might be a bummer for a large number of consumers.

Optane Memory SSDs are expensive 

Intel’s market share has taken a hit by the recent rise in the adoption and popularity of the AMD’s processor and chipsets. Therefore it has envisioned a world where Optane Memory equipped system are running the show which also ends up giving a remarkable performance over the hard drive only system which has become a norm in today’s society.

The pricing for the Optane Memory drive has been kept at $44 for 16GB version while $77 for the 32GB version. Over the years the prices for the flash memory drive has declined rapidly which had made it possible to buy the SSDS for ordinary usage with pretty ease.

Therefore Intel Optane Memory will get a stiff competition for the Flash drive which happens to be first choice of the consumers at the world. Pricing will play a major role in the overall success of the Optane Memory products. Currently buying a 32 GB Optane Memory drive will costs as much as 256 Gb class SSDs while 512 GB class will cost as much as the 25TB hard drive. Intel is hoping that the performance driven Optane Memory will help in creating a niche market for it in upcoming days.

Car Genie: AA Device Predicts Car Breakdowns Before They Happen

Car Genie
It is quite risky if our car suddenly collapses or breaks down. Most of the car owners know that it is not possible to detect any potential breakdown in advance. But, now, you may be able to get rid of such risk, while you are driving your car. With the significant development in automobile industry, there is an introduction of a special tool, Car Genie. It helps in predicting the breakdown prior to anything happens to you.

You know that many of the modern car engineering experts have tried to reduce the risk of breakdowns, while manufacturing the vehicles. However, Automobile Association of the United Kingdom has attempted to give the utmost assistance to the car owners with its new tool, Car Genie. This company works with the aim of reducing the incidents of car collapse as much as possible.

Use Car Genie in a simple way-

The latest device Car Genie, allows self-installation process, and it is to be plugged to the on-board diagnostics point of a vehicle. Users have to install software, which enable them in realizing the probability of breakdown. The system has an ability to interpret EOBD of a vehicle instantly. Then, it delivers all the data to the related software. It also gives notification, which may be seen by driver after or before operating the car.
Car Genie has turned out to be the most advanced product of AA. The company has taken the right step to prevent customers from vehicle breakdown risk. This device will be accessible exclusively to AA associates from May in 2017.

Trials arranged by AA to test the product Car Genie-

Almost 10,0001 car drivers have been involved for the trial of this new tool. AA may also show much data to prove that they are striving to assist drivers in making out the faults at a very early stage. These faults include battery degradation and overall condition of vehicle.

At the time of making experiment, all the faults are tracked in cars of users, and they are related to ignition system, EGR and also air flow. With the identification of faults, it is also possible to analyze the system faster and find out the remedy immediately.

It may save the car owners from hazards and inconvenience, while they are on the highway. Moreover, after sending notifications and recommendations, the company may also provide support by calling their members. They help drivers in repairing the issue.

Within few minutes, as the users can get advice, they may continue the trip again. The outcomes of trial have revealed that almost 49 percent of drivers comprehend problems with vehicle. 66 percent of the vehicle users know the way of driving automobile economically. However, 47 percent of the car owners have informed that Car Genie is good to make their driving safer than before.

As the app collects data on location and driving mode of users (such as, speed, acceleration or braking), some skeptics may consider it to be a privacy risk. But, it is hoped that most of the car drivers will accept it in future.

Stanford Scientists Reveal How Grass Developed a Better Way to Breathe

Grass
Stomata – Holes in Leaves of Plant – Take in CO2, Give Out Oxygen


When we recall our first lesson in photosynthesis we think of the stomata, the holesin the leaves of plants which tend to take in carbon dioxide giving out oxygen together with water vapour. During the 400 million years from the time the plants inhabited the land, these holes seemed to stay unchanged but for one main exception namely grasses.

The plants that tend to make up around 60% of the calories which people consume all over the world is said to have a modified stoma which experts are of the belief that it makes them capable of withstanding drought or even high temperature.

An increased productivity of grass stomata has now been confirmed by Stanford University scientists who have gained some knowledge on how they tend to grow. Their discoveries, conveyed in the issue of Science of March 17 could be beneficial in cultivating crops that would flourish in a changing climate.

Professor of biology and senior author of the paper, Dominique Bergmann, stated that eventually they have to feed people and the climate is changing, regardless of the cause, they still tend to depend on plants in order to survive irrespective of the climate they may have.Grasses that comprise of corn, rice and wheat tend to develop various stomata that could have been helpful in spreading at the time of prehistoric era of improved global dryness.

Food & Agriculture Taken for Granted


Stomata tends to have two supposed `guard cells’ having a hole in the centre which opens and closes based on how the plant requires to steady its gas exchange. Should the plant require more carbon dioxide or needs to cool with the release of water vapour, the stomata tends to open and if it needs to conserve water they then are inclined to remain closed.

The unusual structure of the grasses improved on recruiting two extra cells on each side of the guard cells, enables little additional spring with the opening of the stomaalso tends to respond much more quickly and sensitively to changes in light, temperature or humidity which occurs in the course of the day. Scientists expect that by being aware on how grass developed this system, they would be capable of creating or selecting edible plant which could endure dry as well as hot environments that would probably be more predominant with the changes in climate.

According to Michael Raissig, a postdoctoral research in the Bergmann lab and lead author of the paper commented that they take food and agriculture for granted and it is not something the `first world’ had to deal with but there were still large areas of the world that suffer from famine and this would be on the rise.

Unusual Stomata of Grasses – Extra Efficient `Breathers’


Moreover the human population would be exploding in the next 20 to 30 years, most of which would be in the developing world which is also where the changes in climate would be having the major effect.

As per the scientists, the unusual stomata of the grasses tend to make the plants extra efficient `breathers’. The researchers, however urged by curiosity together with a desire for developmental biology, planned to test that theory. They located a mutant of wheat relative Brachypodium distachyon which had two celled stomata. In association with the Berry lab at the Carnegie Institution for Science, the team then compared the stomata from the normal four celled stomata to the mutant.

They not only confirmed that the four-celled type seems to open wider and faster but identified which gene had created the four –celled stomata, though it was not the gene they were expecting. Raissig stated that since it was a grass specific cell type they were of the belief that it would be a grass specific factor also. Rather than depending on a totally new mechanism, the recruitment of the additional cells appears to be organised by a well-studied factor known to switch other genes on and off.

Wheat Brachypodium


That factor in other plants seems to be present in guard cells where it is involved in their progress. The team discovered that in grasses the factor migrated out of guard cells and directly into two surrounding cells, recruiting them in the formation of the four-celled stomata.

From the evolutionary period, humans have produced and propagated plants which had produced the types of food they desire and which could survive the extreme climate. Dominique Bergmann, also a Howard Hughes Medical Institute investigator commented that they were not consciously breeding for stomata though they had been unconsciously selecting them.

He further added that they wanted something which is more drought resistant or something which could work better in higher temperature, or something which is just capable of taking in carbon better and often what they tend to actually do is select for numerous properties of stomata.

In the research led by Bergmann, the researchers utilised a relative of wheat Brachypodium in demonstrating that all grass stomata having four-cell configuration inclusive of two subsidiary cells were more responsive to changed environmental condition, having a wider range of holes for opening and closing of pores and it was this sensitivity which probably improved the performance of the plant especially in high temperatures or famine conditions.

Gene – BdMUTE


Moreover, the team comprising of lead author Michael Raissig together with the others, utilised sophisticated research techniques in identifying specific gene which enabled Brachypodium to form the imaginative subsidiary cells. The gene known as BdMUTE, encodes a protein which is said to be a `master regulator’ of cell behaviour by turning on and off the other genes which tend to give the cells their exceptional properties.

Deprived of the master regulator, Brachypodium stomata looks like the primitive two-celled stomata which is located in other plants. According to the scientists, due to the flexibility together with the productivity of grass, it seems to make the understanding of this plant family dangerous for the survival of humans.

Irrespective of genetic modification or selective breeding, scientists someday would be capable of using these discoveries in producing the other plants with four-celled stomata. Besides, this could also be one of the several changes, to chloroplasts or enzymes, for instance which would be helpful for plants photosynthesize much more in an efficient manner in feeding an ever growing population.

The research had been financed by Swiss National Science Foundation, The Gordon and Betty Moore Foundation, the U.S. Department of Energy, the National Science Foundation together with the Howard Hughes Medical Institute.
