Nintendo fans may be anxiously awaiting next March’s supposed NX launch (and The Legend of Zelda: Breath of the Wild), but the Japanese gaming giant has a little something up its sleeve in the meantime: a re-release for the iconic NES. Dubbed the Nintendo Entertainment System: NES Classic Edition, the console comes in the form of a miniaturized, HDMI-equipped take on the original and comes with 30 games built right in. Said Nintendo of America President and COO Reggie Fils-Aime:

We wanted to give fans of all ages the opportunity to revisit Nintendo’s original system and rediscover why they fell in love with Nintendo in the first place. The Nintendo Entertainment System: NES Classic Edition is ideal for anyone who remembers playing the NES, or who wants to pass on those nostalgic memories to the next generation of gamers.

Players will even be able to pick up a second controller for just $10 USD when the revamped NES drops this fall. And best of all? The mini console will only run you $60 USD.

A team has used simple quantum processors to run “quantum walk” algorithms, showing that even primitive quantum computers can outperform the classical variety in certain scenarios—and suggesting that the age of quantum computing may be closer than we imagined.

By now, most readers of Futurism are probably pretty well acquainted with the concept (and fantastic promise) of quantum computing.

For those who aren’t, the idea is fairly (!) simple: Quantum computers exploit three very unusual features that operate at the quantum scale—that electrons can be both particles and waves, that objects can be in many places at once, and they can maintain an instantaneous connection even when separated by vast distances (a property called “entanglement”).

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.

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 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.

Physics, as you may have read before, is based around two wildly successful theories. On the grand scale, galaxies, planets, and all the other big stuff dance to the tune of gravity. But, like your teenage daughter, all the little stuff stares in bewildered embarrassment at gravity’s dancing. Quantum mechanics is the only beat the little stuff is willing get down to. Unlike teenage rebellion, though, no one claims to understand what keeps relativity and quantum mechanics from getting along.

Because we refuse to believe that these two theories are separate, physicists are constantly trying to find a way to fit them together. Part-in-parcel with creating a unifying model is finding evidence of a connection between the gravity and quantum mechanics. For example, showing that the gravitational force experienced by a particle depended on the particle’s internal quantum state would be a great sign of a deeper connection between the two theories. The latest attempt to show this uses a new way to look for coupling between gravity and the quantum property called spin.

I’m free, free fallin’

One of the cornerstones of general relativity is that objects move in straight lines through a curved spacetime. So, if two objects have identical masses and are in free fall, they should follow identical trajectories. And this is what we have observed since the time of Galileo (although I seem to recall that Galileo’s public experiment came to an embarrassing end due to differences in air resistance).

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.
