Researchers Engineer Concocted Shape Shifting Noodles

I can say even your grannie can play with the noodles or spaghetti the one that MIT researchers has invented. Yes, these spaghetti/ noodles caters a lot more fun than the normal noodles can't. What so fun about these edible films? This MIT team has made the dining experience more synergistic and lot of fun. Just add water in it and you find these can transform their shapes.

The MIT's Tangible Media Group, have commix something similar to the eatable origami, that is in the shape of flat sheets of starch and gelatin. If you immersed in water, immediately they shoot into 3D formations, that comprises of regular shapes of pasta such as macaroni, noodles and rotini. These edible three-dimensional formations can also be skillfully arranged to crimp into the form of a flower and other irregular designs. To play with these culinary prospective, the MIT researchers formulated flat discs that wrap up around caviar, akin to cannoli, and spaghetti that impromptu divides into littler noodles while soused in hot stock. They have presented their work to the Association for Computing Machinery’s 2017

This MIT's team describes that these edible 3D formations are not only the art of culinary performance, but it is a functional way to cut down food-shipping costings.

The edible films could be piled together and shipped to the customers, so alter into their ultimate shape later, while plunged in water. If you make a perfect pack of it, you will gain 67 percent of package will retain empty says the co author of the paper.

Programmable pasta

MITs researchers, Wang and Yao had been working the effects of respective materials to moisture. They were working generally with a definite bacterium that can metamorphose its form, shrinking and enlarging in effect to humidness. Coincidentally, that particular bacterium is used to ferment soybeans to prepare a regular Japanese dish called as natto. They worked with gelatin, which of course spread out while it takes up water.

This material can spread out to respective degrees that depends on the density. Then the team researched to control the bending structures of the pasta, so that they create various 3D shape-changing gelatin sheets. These gelatin sheets were covered with cellulose strips that controls the amount of water the gelatin sheet can absorb. This cellulose strip act as a water barrier! The print the cellulose onto the gelatin sheets, that can predictably control the shapes response to water and the shapes that it finally expected.

Designing for a noodle democracy

Wang and Yao formulated various different structures from the gelatin sheets, from macaroni like designs, to structures that matches flowers and horse saddles. The team showed their newly invented edibles to the head chef of a high-class Boston bistro. These two professionals designed some culinary creations.

They transcribed the cellulose shapes and the attribute of entire structures they were able to make, and as well tested properties such as strength, make all this into a database. This team used a lab 3-D printer to shape cellulose onto the gelatin films, merely they have defined ways in which we can produce akin effects with more common method, such as screen printing. With this online tool can render design instructions, and a startup establishment can transport the materials to you. They want to change the design of noodles.

Next Generation Mapping Drone

New mapping drone records areas ten times faster than before

Drones are called as remote-controlled aerial vehicles (UAVs - unmanned arial vehicles) can be both independent / machine-controlled flying craft, and also human-controlled aircraft.

The application areas are diverse with these wonderful machines enhanced with technology. Either as a pure hobby object for pure flying or even filming / photography or for professional occasion. On the other hand, they can be also used as military drones / combat drones.

Aerial photography = photography and video technical controls on, for example, high voltage masts and buildings various surveying techniques in the forestry different exploration areas and research in animal protection at the police and fire brigade. Hence the area of application of these drones are increasing day by day in various fields. And also there are a lot of new researches have been conducted to technology enhance these unmanned vehicles. Recently the technical team has formulated a mapping drone that records the ground ten times faster.

The Drone named “Marlyn”

Up to 60 kilometers per hour fast is a mapping drone that has developed the start-up Atmos UAV, a spin-off from the Technical University of Delft in the Netherlands. This technology makes it much faster than almost all conventional airplanes of this type. The reason: "Marlyn" has wings like an airplane, but can still start vertically. The rotors can be rotated by 90 degrees. In the horizontal flight they can use all their strength to move Marlyn forward. The rotors of normal drones have to provide additional buoyancy.

One square kilometer in 30 minutes

The engineers at Atmos has enhanced this mapping drone with wonderful technology that developed Marlyn specifically for taking pictures of the earth's surface. The hybrid mapping drone creates a certain area ten times faster than a conventional aircraft. The first user is the Dutch company, which sees itself as a leader in the use of drones for industrial and agricultural purposes. Marlyn – the mapping drone creates an area of one square kilometer in just 30 minutes. The resolution is three centimeters in this driving mode. The maximum is 1.5 centimeters. This means that a pixel of the recorded image actually has an extension of 1.5 centimeters. In other words, a ten-cent coin can be easily identified.

Rain does not matter to Marlyn

To start and land, this mapping drone needs an area of two by two meters. It can fly in almost any weather. Rain does not matter to her. It must remain on the ground only in strong winds. "With the special features of this mapping drone, we create even the most demanding tasks," says Pieter Franken, one of the founders of Skeye.

Marlyn is wearing a high-resolution camera. Her job makes her autonomous, but after careful preparation. In the first step, by this wonderful technology a flight plan is drawn up that takes into account the required accuracy of the images and the terrain to be mapped. Then start the mapping drone and the data recorder on board at the push of a button. When this mapping drone has landed after the work has been done, the stored image data are read out and edited with any evaluation software.

What you need to know about Bitcoin after the WannaCry Ransomware attack?

After the recent worldwide attack of ransomware, Bitcoin was highlighted in the news again. The harmful software locks the victim’s access to all their files and data and refuses to grant them access unless a ransom is paid in the form of at least $300 in bitcoin. This leaves one wondering what exactly is bitcoin and why do hackers want their payments in this form?

What is bitcoin?

Bitcoin is a type of a digital currency. One can buy dollars or euros with it and also one can trade any other currency. It is stored in an online wallet and through this wallet, one can use bitcoin online and also in the physical world for purchasing services and goods. Bitcoin is also supported by PayPal. Bitcoin also has valuation and it’s price keeps fluctuating up and down, just like any other currency.

What's different about bitcoin?

Usually, while purchasing something online, one uses a credit card or a debit card. This card connects to information about the user, such as the name and the billing address. One can use bitcoin the very same way one uses debit or credit cards and the transactions made are completely anonymous. This can’t be used to personally identify you. Whenever one trades in bitcoin, a private key is used which is associated with the user’s wallet and a code is generated, called an address. This address is then publicly linked with the transaction but no personal details and information are identified. In this way, every bitcoin transaction is recorded and is signed securely in an open ledger that can be viewed and checked by anyone. Thus, bitcoin can be used to protect one’s privacy.

Is this why the WannaCry hackers chose Bitcoin as a form of payment?

Most possibly, yes. Bitcoin has gained its reputation as a technology that can facilitate crime in the news media. Although the identities of users making bitcoin transactions are not revealed, law enforcement can trace these transactions and the movement of bitcoin with the help of the public ledger. Online criminal operations that have used bitcoin, have been successfully prosecuted by the Justice Department.

Law Enforcement and WannaCry

The government is already investigating these attacks. White House homeland security adviser Tom Bossert stated that the process of finding out who is behind the crime, also called as attribution, is a generally tough process in computer attacks. Most of the times, the attackers are not easy to catch hold of as they are beyond the reach of U.S. law enforcement. Their activities are hidden behind multiple layers of security.

Money Collected by the Attackers

According to Quartz, the news site tracking the amount of money in the hackers’ wallet, so far the amount looks to be about $55,000. It’s not a lot of money considering that the European Union Law enforcement agency, Europol, has said that more than 200,000 computer systems have been affected. Still, in recent years, the value of a single bitcoin has seen a steady rise. An all-time high price of $1,830 per bitcoin was seen just hours before the WannaCry attack began to spread. However, after the attack was revealed, the price fell by $200. Looking at how easily hackers can attack with ransomware, acquiring even a handful of bitcoin and keeping a hold of it for sometime can help the cyber-criminals gain a large sum of money.

Construction Begins on Google’s Massive Seattle campus in Amazon’s Backyard

Google’s New Campus – Established by Paul Allen - Vulcan Read Estate

Works has begun on the new campus of Google in Seattle’s South Lake Union neighbourhood, on the outskirts of global headquarters of Amazon. The project is being established by Vulcan Real Estate of Paul Allen and tends to span two whole blocks and would comprise of office space of around 600,000 square feet, together with residential tower on every block with a combined 149 units according to Lori Mason Curran investment strategy director of Vulcan Real Estate.

Commencement of the work had started earlier in the month on the project that had been announced last year which will be reaching completion in early 2019. Vulcan also tends to have an adjacent block which is not a portion of the project of Google. According to Mason Curran, the site is intended for 216 residential units and 161,000 square feet of office space. It is said that Vulcan would not begin this block till it lands a tenant.

The main player for long has been Amazon in South Lake Union. However, the entry of Google in the neighbourhood down the road together with the rapidly growing presence for Facebook should provide plenty of competition for top talent.

Structure – Begin in Phases 2017 - 2019

Presently, Seattle area footprint of Google comprises of offices in the Fremont neighbourhood and the Eastside suburb of Kirkland, Wash. It is uncertain what Google intends to do with its Fremont space when the new Seattle campus seems to be ready. However at the moment, investing in the neighbourhood, Google had signed a deal, earlier this year to sublease the former sound Mind & Body Gym space in 2014 that Tableau had altered into around 50,000 square feet of tech office space, for its engineering team.

The structure would begin in phases from 2017 and would complete in 2019. According to an official from Vulcan, Google has agreed to leases which would be lasting 14 to 16 years, a new sign of its long-term commitment to the Seattle region. Joined with the recently expanded offices in Kirkland, Wash of Google, the technology giant would be approaching 1 million square feet in the area with this latest space. Presently Google tends to have over 1,900 employees in Washington State, in offices in Seattle and Kirkland.

South Lake Union – Thriving Hub

Google would be moving from its present location in Seattle’s Fremont neighbourhood, wherein the space had been constrained in recent years considering the rapid expansion of Tableau Software together with the other technology companies. Clyde McQueen, site Lead for Google Seattle had mentioned in a news release that South Lake Union is a thriving hub and they were excited for the new space. They loved being in the Fremont neighbourhood though would need more breathing space.

They are yet to catch a view of Lake Union, from the new location. Besides providing a bigger footprint for Google in the city, the news is prominent since Amazon is not the one taking the building and Vulcan had established the online retailer’s prevailing campus in the South Lake Union neighbourhood. More focus has been done by Amazon on its expansion in the neighbourhood towards the south where it is rolling its own three block campus on the northern outskirts of downtown Seattle.

A Google Engineer Recreated a DSLR Photo Using a Nexus 6P with Absolute Perfection

Create Image Utilising Nexus 6P

Smartphone cameras have been enhanced beyond our imaginations and from the rough VGA cameras which the earlier phones featured, to the updated Dual Cameras lots that tend to replicate DSLR type portrait shots with perfections, smartphone photography had progressed to great extent.

However there seems to be one segment wherein smartphones are unable to compare up to the DSLRs low light photography and Google has plans of changing it. OEMs tend to advertise low-light photography as a feature in their phone cameras though usually it is more of a trick. An engineer Florian Kainz working on Gcam team of Google, the team behind the legendary camera of the Google Pixel had been challenged by his colleague to develop a night shot of the Golden Gate Bridge which had originally been shot by a DSLR utilising a smartphone camera.

He had accepted the challenge and had managed in creating the image utilising the Nexus 6P together with some post-processing and created an image using smartphone providing us a glimpse of what Google could do in making night-time outdoor photography a real thing with the support of smartphones.

Technique for Shooting Milky Way – Google Pixel

Using a technique he was capable of shooting the Milky Way utilising the Google Pixel from the Californian coast where the nights tend to get very dark and the stars are said to be the only source of light on nights when the moon is not in sight.

But at 9 to 10 megapixels, the subsequent photos did not seem to be as high quality as a DSLR, though the details seemed to be there. With the results of the Pixel together with the Nexus 6P, it is clear that the final frontier of smartphone photography is on the threshold of being penetrated.

Software has been developed by OEM in order to process the images internally, with all the additions together with the subtractions as well as the averaging of the multiple photos to make night point and shoot photography utilising a smartphone, a reality. But one can’t take photos yet the same way with your smartphone and the Google Pixel tends to come the nearest in taking such images though not close enough.

HDR+ Feature

Google is said to utilise the HDR+ feature that swiftly takes 10 short exposure shots and averages them to form an individual image to eliminate blur and noise at the time of collecting adequate light for good photos at practically low-levels though it will still tend to be impractical in very low-light, moonlight landscapes for example, or starlight photos.

To achieve the image, Kainz had installed a custom Android app which enabled him to set the ISO, shutter speed and focus manually. He also utilised a tripod to keep the phone steady. The custom app was to eliminate the maximum 4-second exposure time for taking longer exposure shots in order to lessen the ISO setting and thus reduce the noise.

When the shutter button is pressed, the app tends to wait a few seconds and then takes up to 64 frames with the selected exposure and ISO settings. Thereafter it saves the frames as DNG file wherein these are later exported to a PC to post-process into one.
