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

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…

Gold and Lasers Produce Plasmonic Nanobubbles to Kill Residual Cancer Cells

A team of scientists headed by folks at Rice University have developed a way of killing off neoplastic cells that often remain after surgical procedures and end up causing a recurrence of cancers. The investigators managed to produce gold nanoparticles with cancer antibodies attached to them that seek out specific cancer cells. The gold nanoparticles are sensitive to laser light, quickly heating up and producing a so-called plasmonic nanobubble within surrounding liquid. This destroys the cancer cell to which the antibody was attracted, but it also pinpoints the location where the killing occurred.…

Novel 3-D “Smart” Sutures for Wireless Collection of Biological Data

The field of smart wearable systems has just gotten a boost thanks to researchers from Tufts University.  A team of engineers has developed a novel 3-dimensional thread-based diagnostic platform that, when sutured into tissue, collects a range of real-time diagnostic data wirelessly, including pH, glucose levels, temperature, stress, strain, and pressure.  Physical and chemical nanosensors, microfluidics, and electronics integrated into various types of conductive threads, including cotton and synthetic fibers, are connected to a wireless electronic circuit.  The result is a suture that can penetrate tissue, sense various factors in…

Synthetic immune cells: a possible solution to antibiotic resistance?

Dr. Thomas J. Webster – the Art Zafiropoulo chair and professor of the Department of Chemical Engineering at Northeastern University in Boston, MA, and president of the US Society for Biomaterials – and colleagues have created synthetic immune cells, referred to as polymersomes. These polymersomes can mimic the behavior of natural immune cells, according to the team, opening the door to a way to boost infection-fighting capability among individuals with compromised immune systems. “They can significantly aid someone who has a failing immune system, or for someone who needs a…

Rapid Test Identifies Protein Disease Biomarkers Within 10 Minutes

Scientists at University of California, Los Angeles have developed a rapid new test for spotting proteins within blood and plasma. Unlike current tests that can take up to four hours to perform, the team’s technique takes only 10 minutes and can be done right inside the doctor’s office instead of a clinical lab.   Typically, enzymes are used to amplify the protein signal, but they introduce their own problems such as difficulty in handling, high associated costs, and false positives. Instead, the team did away with enzymes altogether and focused…

Facebook to position internet beaming satellite over Africa next year

Facebook is set to take its worldwide internet project to new heights, all the way to geostationary orbit, to be specific. The social media giant has announced a new partnership with French firm Eutelsat, with plans to launch a satellite into space next year in hope of bringing millions of people in Sub-Saharan Africa online. The satellite is already under construction. Being built by Israeli firm Spacecom, the AMOS-6 satellite is designed to address the gaps in internet access throughout West, East and Southern Africa that cannot be filled by…

iBeacon technology powers a new Smart Public Transport project in Bucharest

Romanian tech firm Onyx Beacon is teaming up with the local authorities in Bucharest to install 500 iBeacon devices on buses across the metropolis. It’s hoped that the new Smart Public Transport (SPT) initiative will make the city safer and more accessible for the estimated 12,000 visually impaired citizens who live there. While many of us take the act of hopping on or off a bus for granted, for those with eyesight problems it can be both difficult and dangerous. Through the installation of the Enterprise Beacons – fitted to…

MIT’s Swarm chip architecture boosts multi-core CPUs

For nearly 10 years, computer processors have been getting faster by using multiple cores rather than raising their individual speeds. This measure makes our PCs and smartphones more power-efficient, but also makes it much trickier to write programs that take full advantage of their hardware. Swarm, a new chip design developed at MIT, could now come to the rescue and unleash the full power of parallel processing for up to 75-fold speedups, while requiring programmers to write a fraction of the code. Developed by Prof. Daniel Sanchez and team, Swarm is…

India Marks Success in First Reusable Spacecraft Test

The Indian Space Research Organisation is entering the next generation of space travel. The ISRO on Monday successfully launched its pint-sized Reusable Launch Vehicle (RLV-TD) prototype from the Satish Dhawan Space Centre in Sriharikota, according to an announcement from the space organization. The first test flight marks a milestone for ISRO, which started developing its concept for a reusable launch vehicle  nearly a decade ago. Miniature Rocket The RLV-TD is just 23 feet tall, and weighs about 1.75 tons. For comparison, SpaceX’s Falcon 9 launch vehicle stands 224 feet upright, and weighs over 600…
