Is your brain an analog or digital device? New research surprises

Posted by in category: neuroscience

Compare an analog and a digital audio recording medium. VHS video tape — an analog medium — stores a continuous curve of modulated audio/visual information. In a digital CD continuous audio is sliced into 44,100 frames a second, and represented by discrete numbers.

On playback the sounds are presented as continuous, much as the individual still frames of a motion picture appear continuous when played back fast enough. Most people can’t hear the difference between digital and analog recordings, me included, but those who say they do may spend thousands on turntables and tube amps to get the full analog experience.

From measurements, we know that neuron currents are continuous, not step functions. The important question is how is the information represented by these signals? Most psychological research assumes continuous or analog representation, but in the lengthy paper Is Information in the Brain Represented in Continuous or Discrete Form? James Tee and Desmond Taylor of the University of Canterbury make a strong theoretical and experimental case for digital data.

This AI can see you through walls

Posted by in category: robotics/AI

X-ray vision has long seemed like a far-fetched sci-fi fantasy, but over the last decade a team led by Professor Dina Katabi from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has continually gotten us closer to seeing through walls.

Their latest project, “RF-Pose,” uses artificial intelligence (AI) to teach wireless devices to sense people’s postures and movement, even from the other side of a wall.

Chip upgrade helps miniature drones navigate

Posted by in categories: computing, drones

Researchers at MIT, who last year designed a tiny computer chip tailored to help honeybee-sized drones navigate, have now shrunk their chip design even further, in both size and power consumption.

The team, co-led by Vivienne Sze, associate professor in MIT’s Department of Electrical Engineering and Computer Science (EECS), and Sertac Karaman, the Class of 1948 Career Development Associate Professor of Aeronautics and Astronautics, built a fully customized from the ground up, with a focus on reducing and size while also increasing processing speed.

The new computer chip, named “Navion,” which they are presenting this week at the Symposia on VLSI Technology and Circuits, is just 20 square millimeters—about the size of a LEGO minifigure’s footprint—and consumes just 24 milliwatts of , or about one-thousandth the energy required to power a lightbulb.

Thousands of Swedes are inserting microchips into themselves – here’s why

Posted by in categories: bioengineering, computing

Often, different biohacking scenes reflect the different societies and cultures in which they develop. So, for example, European biohackers generally differ from their North American counterparts. North American groups are concerned with developing alternatives to the established healthcare practices. European groups, meanwhile, are more focused on finding ways of helping people in developing countries or engaging in artistic bio-projects.

Sweden’s deep relationship with digital technology helps explain why its biohacking scene is so unique.

Opinions on #ArtificialIntelligence are a dime a dozen, unless you’re hearing from one of the field’s pioneers

Posted by in category: robotics/AI

Join us at D60, DARPA’s 60th anniversary symposium, to learn from Ron Brachman about how #AI rose to prominence.

Artificial Intelligence has experienced waves of excitement before, but we have never seen the kind of worldwide enthusiasm that we see now, especially in the commercial sector, where AI has become the central mission of some of the world’s most powerful tech companies. DARPA is known for being the first supporter of AI research and panelists will highlight the impetus DARPA provided to the field’s most central technological areas, and give insights about where the field is going next.

U.S. faces ‘unprecedented threat’ from China on tech takeover

Posted by in categories: law, military

I dont see it as a threat. Honestly, some of the US scientific community was getting really cocky, and really lazy, which is never a good combination. The US scientific community wanted to lock Crispr in a closet for 50 years. 30 years ago they could of gotten away with it. With China as it is now, they are forced to do research they would of rather hidden away.

China’s “Thousand Talents” program to tap into its citizens educated or employed in the U.S. is a key part of multi-pronged efforts to transfer, replicate and eventually overtake U.S. military and commercial technology, according to American intelligence officials.

The program, begun in 2008, is far from secret. But its unadvertised goal is “to facilitate the legal and illicit transfer of U.S. technology, intellectual property and know-how” to China, according to an unclassified analysis by the National Intelligence Council, the branch of U.S. intelligence that assesses long-term trends.
