Quantum processor for single photons

admin

Scientists have realized a photon-photon logic gate via a deterministic interaction with a strongly coupled atom-resonator system. “Nothing is impossible!” In line with this motto, physicists from the Quantum Dynamics Division of Professor Gerhard Rempe (director at the Max Planck Institute of Quantum Optics) managed to realise a quantum logic gate in which two light quanta are the main actors. The difficulty of such an endeavour is that photons usually do not interact at all but pass each other undisturbed. This makes them ideal for the transmission of quantum information,…

Google Play’s new delta algorithm reduces size of Android app updates

admin

Google today announced Google Play store improvements focused on the size of updates. A new delta algorithm, bsdiff, has been rolled out to further reduce patches for apps and games. Mobile users are sensitive to the amount of data they use, especially when Wi-Fi is not available. Google is thus trying to reduce the data required for Google Play app installs and updates, as well as make data cost clearer to users. Google says that for approximately 98 percent of app updates from the Play Store, only deltas to APK files (the…

Hardening up: New alloy four times as tough as titanium

admin

A chance discovery in a physics lab at Rice University has turned up an ultra-hard material that could usurp the titanium commonly used in today’s knee and hip replacements. Scientists have found that by melting gold into the titanium mix they can produce a non-toxic metal that is four times harder than titanium itself, raising the prospect of more durable, longer lasting medical implants. Emilia Morosan, a professor of physics at Rice University, was carrying out experiments on a magnetic material made from nonmagnetic elements, more specifically, a titanium-gold mix with a…

Nanoparticle lung vaccine protects against HIV, herpes

admin

Scientists have created a type of nanoparticle that they say can effectively deliver vaccines to the lungs, protecting against numerous infectious diseases. This is according to a study published in Science Translational Medicine. Researchers from the Massachusetts Institute of Technology (MIT) say the nanoparticle vaccine could help protect againstinfluenza and other respiratory diseases, as well as prevent sexually transmitted diseases such as HIV, human papilloma virus and herpes simplex virus. The scientists note that many viruses and bacteria infect humans through mucosal surfaces, such as those in the lungs. Therefore, they wanted to develop vaccines that are…

Proteins team up to turn on T cells

admin

The fates of various cells in our bodies–whether they become skin or another type of tissue, for example–are controlled by genetic switches. In a new study, Caltech scientists investigate the switch for T cells, which are immune cells produced in the thymus that destroy virus-infected cells and cancers. The researchers wanted to know how cells make the choice to become T cells. “We already know which genetic switch directs cells to commit to becoming T cells, but we wanted to figure out what enables that switch to be turned on,”…

Elon Musk’s Hyperloop: A Pragmatic Vision of the Future

admin

Los Angeles to San Francisco in 30 minutes? In August, billionaire entrepreneur Elon Musk announced his vision for Hyperloop, a levitating train that would shoot through a low-pressure, above-ground tunnel at 760 mph. Musk is famous for futuristic transit, such as his electric car company Tesla Motors and commercial space travel business SpaceX. But he has no intention of building a functional Hyperloop. His aim was to generate buzz with the idea, in the hope that others would develop and build it. The technology itself is old news. In 1972,…

How Data Science is Interconnected to Urban Design, Development of Infrastructure and Risk Management

admin

How Data Science is Interconnected to Urban Design, Development of Infrastructure and Risk Management The recent advances in data science are influencing the domain of urban design, infrastructure development as well as risk management in a game changing way. Data science can therefore be viewed as an asset in the building of more intelligent and sustainable cities around the globe through better city planning, predictive maintenance, or risk management. Additionally, urban design has progressed due to the contribution of data science because architects of cities today use real time information…

Humans can now use mind control to direct swarms of robots

admin

There have been some amazing breakthroughs that enable humans to control a single machine with their thoughts. The next step is figuring out how to operate an entire fleet of robots with mind control. A team of researchers at Arizona State University’s (ASU) Human-Oriented Robotics and Control Lab have developed a system for managing swarms of robots with brain power. ASU’s new system can be used to direct a group of small, inexpensive robots to complete a task. If one robot breaks down, it’s not a big loss, and the rest can…

Nvidia’s eye-tracking system blurs the lines for more immersive VR environments

admin

The human eye can only focus on one surprisingly small area at a time, while our peripheral vision gives us the general gist of what else is nearby. That means a lot of processing power that goes into fully rendering virtual reality environments in focus is wasted when you’re only really taking in a small area of the screen at any given time. Nvidia has developed a rendering technique that allows that wasted processing power to be redirected to allow developers to create more immersive VR environments. The technique, called…

Boeing unveils game-changing autonomous submarine

admin

When you hear the name “Boeing,” chances are you think of aircraft. The fact is, however, the company has also been developing underwater vehicles since the 1960s. Its latest such creation, the Echo Voyager, is designed to operate autonomously for months at a time. The 51-foot (15.5-m)-long Voyager joins two other Boeing unmanned undersea vehicles, or UUVs: the 32-ft (9.8-m) Echo Seeker and the 18-ft (5.5-m) Echo Ranger. Like them, it’s designed to autonomously gather data underwater for scientific, military or other purposes. Unlike them, though, it’s not limited to missions lasting no…
