DARPA Invests $7.5 Million for Implantable Biosensor that are 3 millimeters long and 500 microns in diameter

Profusa (South San Francisco, CA) has won a $7.5 million grant from the Defense Advanced Research Projects Agency (DARPA) and the U.S. Army Research Office for further development of its tissue integrated biosensor technology, the company said Tuesday.

The U.S. military sees value in the technology improving mission efficiency through real-time monitoring of combat soldier health status.

“Profusa’s vision is to replace a point-in-time chemistry panel that measures multiple bio­markers, such as oxygen, glucose, lactate, urea, and ions with a biosensor that provides a continuous stream of wireless data,” Ben Hwang, PhD, Profusa’s chairman and CEO, said in a news release.

Deep Learning Algorithm Automatically Colorizes Photos

This is one of those sites you’re going to want to try yourself. Take any black and white image, feed it to the algorithm, and watch as it spits out its best guess at a color version, which is often quite convincing.

Using a deep learning algorithm developed by Richard Zhang, Phillip Isola, and Alexei Efros of UC Berkeley, the process was trained on one million images. Though it currently fools humans only 20% of the time, that’s still a significantly higher rate than previous iterations and represents an exciting step forward, and further training should only increase that rate. Imagine a time when Photoshop can colorize a photo in one step, leaving the end-user to just tweak a few hues here and there. Such a capability would be huge for restoring old family photos and the like.

I played with it a bit today, and the results were rather interesting. It struggles a bit with skin tones, which may be due to dataset bias (meaning the team may have trained it more with landscape-style images), but often the results are fairly good and definitely close enough that they could be tweaked to believability without a lot of effort.

China Might Float Nuclear Reactors in Disputed Waters

China aims to launch a series of offshore nuclear power platforms to promote development in the South China Sea, state media said again on Friday, days after an international court ruled Beijing had no historic claims to most of the waters.

Sovereignty over the South China Sea is contested by China, the Philippines, Vietnam, Malaysia, Brunei and Taiwan, and any move to build nuclear reactors is bound to stoke further tension in the region.

The China Securities Journal said 20 offshore nuclear platforms could eventually be built in the region as the country seeks to “speed up the commercial development” of the South China Sea.

Optical Magnetic Field Sensor can Detect Ultra-Small Magnetic Fields

Small magnetic fields from the human body can usually only be picked up by very sensitive superconducting magnetic field sensors that have to be cooled by liquid helium to near absolute zero (which is minus 273 degrees Celsius). But now researchers from the Niels Bohr Institute at the University of Copenhagen have developed a much cheaper and more practical optical magnetic field sensor that even works at room temperature or at body temperature.

“The optical magnetic field sensor is based on a gas of caesium atoms in a small glass container. Each caesium atom is equivalent to a small bar magnet, which is affected by external magnetic fields. The atoms and thus the magnetic field are picked up using laser light. The method is based on quantum optics and atomic physics and can be used to measure extremely small magnetic fields,” explains Kasper Jensen, assistant professor in the Center for Quantum Optics, Quantop at the Niels Bohr Institute at the University of Copenhagen.

Is invisibility cloak on its way to reality?

Invisibility cloak has hidden Harry Potter and hobbits from view and now, this sci-fi staple may be moving closer to reality!

Scientists at Queen Mary University of London (QMUL) have made an object disappear by using a composite material with nano-size particles that can enhance specific properties on the object’s surface.

Researchers demonstrated for the first time a practical cloaking device that allows curved surfaces to appear flat to electromagnetic waves.

This Tablet-Toting Military Vest Is Actually a Giant Battery

Smartphones and tablets are being used more frequently in the battlefield, and that means that battery power is more important than ever. Soldiers often carry spare battery chargers in the 90-pound combat packs they carry into war zones, but the batteries are often lost or broken. BAE Systems wants to help lighten the load with its new system that lets soldiers plug electronics directly into their clothing.

The BAE Systems Broadsword Spine is a harness that can be sewn into a soldiers vest, jacket, or belt that carries a battery pack and hides charging wires. The harness places the battery pack on the small of a soldier’s back and includes eight conductive fabric conduits that can be used to connect to a USB port.

Silicon Valley Entrepreneurs Aim To ‘Hack’ the Brain

Woo and other entrepreneurs are using fasts and other tricks to “hack” their brain chemistry like they would a computer, hoping to give themselves an edge as they strive to dream up the next billion-dollar idea. Known by insiders as “biohacking,” the push for cognitive self-improvement is gaining momentum in the Silicon Valley tech world, where workers face constant pressure to innovate and produce at the highest levels.
