Columbia University engineering researchers have developed a new “circulator” technology that can double WiFi speed while reducing the size of wireless devices. It does this by requiring only one antenna (instead of two, for transmitter and receiver) and by using conventional CMOS chips instead of resorting to large, expensive magnetic components.

Columbia engineers previously invented a “full-duplex” radio integrated circuit on… read more

Can a robot handle the slippery stuff of soft tissues that can move and change shape in complex ways as stitching goes on, normally requiring a surgeon’s skill to respond to these changes to keep suturing as tightly and evenly as possible?

A Johns Hopkins University and Children’s National Health System research team decided to find out by using their  “Smart Tissue Autonomous Robot” (STAR)… read more

More evidence that you’re a mindless robot with no free will

How we may confabulate reality and rationalize irrational behavior

The results of two Yale University psychology experiments suggest that what we believe to be a conscious choice may actually be constructed, or confabulated, unconsciously after we act — to rationalize our decisions. A trick of the mind.

“Our minds may be rewriting history,” said Adam Bear, a Ph.D. student in the Department of Psychology and lead author of a paper published April 28… read more

Astronomers discover potentially habitable planets just 40 light years from Earth

Best targets so far for search for extraterrestrial life

ultracool dwarf star-ft

Astronomers have detected three exoplanets just 40 light years from Earth whose sizes and temperatures are comparable to those of Earth. The planets may be the best targets found so far for the search for life outside the solar system.

The results were published Monday (May 2) in the journal Nature.

Because the system is relatively close to Earth, co-author Julien de Wit, a postdoc at MIT, says scientists… read more

IBM makes quantum computing available free on IBM Cloud

You can run real or simulated experiments on an IBM quantum processor
May 3, 2016

Layout of IBM's five superconducting quantum bit device. In 2015, IBM scientists demonstrated critical breakthroughs to detect quantum errors by combining superconducting qubits in latticed arrangements, and whose quantum circuit design is the only physical architecture that can scale to larger dimensions. Now, IBM scientists have achieved a further advance by combining five qubits in the lattice architecture, which demonstrates a key operation known as a parity measurement – the basis of many quantum error correction protocols.

IBM Research has announced that effective Wednesday May 4, it is making quantum computing available free to members of the public, who can access and run experiments on IBM’s quantum processor, via the IBM Cloud, from any desktop or mobile device.

IBM believes quantum computing is the future of computing and has the potential to solve certain problems that are impossible to solve on today’s supercomputers.

University of Cambridge researchers have developed the world’s tiniest engine, capable of a force per unit-weight nearly 100 times higher* than any motor or muscle.

The new nano-engines could lead to nanorobots small enough to enter living cells to fight disease, the researchers say.

Professor Jeremy Baumberg from the Cavendish Laboratory, who led the research, has named the devices “actuating nanotransducers” (ANTs). “Like real ants, they produce large… read more

Harold Cohen: in memoriam

Artist and pioneer in the field of computer-generated art
May 2, 2016

By Paul Cohen

Harold Cohen, artist and pioneer in the field of computer-generated art, died on April 27, 2016 at the age of 87. Cohen is the author of AARON, perhaps the longest-lived and certainly the most creative artificial intelligence program in daily use.

Cohen viewed AARON as his collaborator. At times during their decades-long relationship, AARON was quite autonomous, responsible for the composition, coloring and other aspects… read more

Skull echoes could become the new passwords for augmented-reality glasses

SkullConduct ft

German researchers have developed a biometric system called SkullConduct that uses bone conduction of sound through the user’s skull for secure user identification and authentication on augmented-reality glasses, such as Google Glass, Meta 2, and HoloLens.

SkullConduct uses the microphone already built into many of these devices and adds electronics (such as a chip) to analyze the frequency response of sound after it travels through the user’s skull. The… read more

Deep neural networks that identify shapes nearly as well as humans

You're in your self-driving car, with heavy rain and poor visibility. All of a sudden, a blurred shape appears on the road. What should the car do?

Deep neural networks (DNNs) are capable of learning to identify shapes, so “we’re on the right track in developing machines with a visual system and vocabulary as flexible and versatile as ours,” say KU Leuven researchers.

“For the first time, a dramatic increase in performance has been observed on object and scene categorization tasks, quickly reaching performance levels rivaling humans,” they note in an open-access paper in… read more

Ultrasound allows for transmitting HD video through animal tissues

University of Illinois at Urbana-Champaign engineers have demonstrated real-time video-rate (>30Mbps) “meat comm” data transmission through tissue, which could mean in-body ultrasonic communications may be possible for implanted medical devices, including hi-def video.

For example, a patient could swallow a miniaturized HD video camera that could stream live to an external screen, with the orientation of the device controlled wirelessly and externally by a physician, according to Andrewread more

Just 1 minute of intense exercise produces health benefits similar to 50 minutes of moderate exercise

No time to exercise? Now you have no excuse.

Researchers at McMaster University have found that a single minute of very intense exercise within a 10-minute session produces health benefits similar to those from 50 minutes of moderate-intensity continuous exercise.

Brief bursts of intense exercise are remarkably effective, a very time-efficient workout strategy, according to Martin Gibala, a professor of kinesiology at McMaster and lead author on the study, published online in an open-access paper in the… read more

System predicts 85 percent of cyber attacks using input from human experts

Merging human and machine intelligence reduces false positives by factor of 5
April 25, 2016


Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and the machine-learning startup PatternEx have developed an AI platform called AI2 that predicts cyber-attacks significantly better than existing systems by continuously incorporating input from human experts (AI2 refers to merging AI with “analyst intuition”:  rules created by living experts).

The team showed that AI2 can detect 85 percent of attacks —about three times better than previous benchmarks —… read more
