Flexible sensors turn skin into a touch-sensitive interface for mobile devices

March 4, 2015

iSkin2

Computer scientists at Saarland University and Carnegie Mellon University are studying the potential use of the human body as a touch sensitive surface for controlling mobile devices. They have developed flexible silicone rubber stickers with pressure-sensitive sensors that fit snugly to the skin.

By operating these touch input stickers, users can use their own body to control mobile devices. Because of the flexible material used, the sensors can be… read more

New solar structure cools buildings in full sunlight, replacing air conditioners

Homes and buildings chilled without air conditioners? Car interiors that don't heat up in the summer sun? Tapping the frigid expanses of outer space to cool the planet? Yes.

Stanford University researchers have designed an entirely new form of cooling structure that cools even when the sun is shining, eliminating the need for air conditioning.

Such a structure could vastly improve the daylight cooling of buildings, cars, and other structures by reflecting sunlight back into space.

“We’ve developed a new type of structure that reflects the vast majority of sunlight, while at the same… read more

This app lets autonomous video drones with facial recognition target persons

One small step for selfies, one giant leap for cheap deep-learning autonomous video-surveillance drones
November 19, 2015

Robotics company Neurala has combined facial-recognition and drone-control mobile software in an iOS/Android app called “Selfie Dronie” that enables low-cost Parrot Bebop and Bebop 2 drones to take hands-free videos and follow a subject autonomously.

To create a video, you simply select the person or object and you’re done. The drone then flies an arc around the subject to take a video selfie (it moves with the… read more

Thiel tells Schmidt: ‘Google is out of ideas’

July 18, 2012

Google Chairman Eric Schmidt and investor Peter Thiel took aim at each other in a recent debate, CNET reports.

Schmidt said technology and access to information has increased productivity and quality of life worldwide. Thiel thanked Schmidt for “doing a fantastic job” as “minister of propaganda” for Google. The tech sector has made remarkable strides in the areas of computers and software, he said, but has seen a “catastrophic” failure in other… read more

Real or computer-generated: can you tell the difference?

Training helps humans tell them apart ... but soon, only computers will know what's real or not
February 22, 2016

A Dartmouth College study shows that people find it increasingly difficult to distinguish between computer-generated images and real photos, but that a small amount of training greatly improves their accuracy. (credit: Dartmouth College)

As computer-generated characters become increasingly photorealistic, people are finding it harder to distinguish between real and computer-generated, a Dartmouth College-led study has found.

This has introduced complex forensic and legal issues*, such as how to distinguish between computer-generated and photographic images of child pornography, says Hany Farid, a professor of computer science, pioneering researcher in digital forensics at Dartmouth, and senior author of a paper… read more

Immortal worms defy aging

February 29, 2012

Planarian flatworm

Researchers from The University of Nottingham have discovered how planarian flatworms overcome the aging process to be potentially immortal: they can rejuvenate their telomeres.

The discovery, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and Medical Research Council (MRC), may eventually lead to alleviating aging and age-related characteristics in human cells.

Planarian worms have amazed scientists with their apparently limitless ability to regenerate. Researchers have… read more

D-Wave Systems breaks the 1000 qubit quantum computing barrier

D-Wave Systems has broken the quantum computing 1000 qubit barrier, developing a processor about double the size of D-Wave’s previous generation, and far exceeding the number of qubits ever developed by D-Wave or any other quantum effort, the announcement said.

It will allow “significantly more complex computational problems to be solved than was possible on any previous quantum computer.”

At 1000 qubits, the new processor considers 21000 possibilities… read more

Researchers at BGI (formerly the Beijing Genomics Institute) in Shenzhen, China, the largest gene-sequencing facility in the world, are searching for the quirks of DNA that may contribute to genius in an ethically controversial study.

They are scouring the genomes of 1,600 U.S. adolescents who signed up for the Study of Mathematically Precocious Youth (SMPY) in the 1970s, Nature News reports.

Some geneticists say that the… read more

How terahertz laser scanners will spy on you in airports

Genia

Genia Photonics has developed a programmable picosecond laser that is capable of spotting trace amounts of a variety of substances, including explosives, chemical agents, and hazardous biological substances at up to 50 meters.

It’s basically a spectrometer for radiation in the terahertz band. The beam used by Genia’s spectrometer is capable of penetrating most materials including wood, leather, cloth, ceramics, plastic, and paper, and can essentially… read more

Wind could meet many times the world’s total power demand by 2030, Stanford researchers say

September 11, 2012

wind farms

Researchers at Stanford University’s School of Engineering and the University of Delaware have used what they call the “most sophisticated weather model available” to  meet many times the world’s total power demand by 2030 — in fact, enough to exceed the total demand by several times, even after accounting for reductions in wind speed caused by turbines.

In related news today, Lawrence Livermore and Carnegie Institute researchers have found… read more

A radical new holistic view of health based on cooperation and disease based on competition

Researchers at The Mount Sinai Medical Center have developed a radical holistic view of health — seeing it as a cooperative state among cells, while they see disease as result of cells at war that fight with each other for domination.

Their unique approach is backed by experimental evidence. The researchers show a network of genes in cells, which includes the powerful tumor suppressor p53,… read more

Cray unveils Cray XC30 supercomputer, capable of scaling to 100 petaflops

Cray XC30 supercomputer (credit:

Cray Inc. has launched the Cray XC30 supercomputer, previously code-named “Cascade,” designed to scale high performance computing (HPC) workloads of more than 100 petaflops, with more than one million cores.

Cray did not specify whether the 100 petaflops was Rpeak or Rmax, or when a 100 petaflops installation might be planned.

China’s Guangzhou Supercomputing Center also recently announced the development of a supercomputer… read more

Making solar power competitive with coal

By the end of the decade, U.S. manufacturers could make solar panels that are less than half as expensive as the ones they make now.

At 52 cents per watt, that would be cheap enough for solar power to compete with electricity from fossil fuels, according to a new study by MIT researchers in Energy & Environmental Science.

Assuming similar cost reductions for installation and equipment, solar power would… read more

Finding ET may require giant robotic leap

NGC Galaxy

Autonomous, self-replicating robots — exobots — are the way to explore the universe, find and identify extraterrestrial life and perhaps clean up space debris in the process, according to John D. Mathews, professor of electrical engineering at Penn State.

“The basic premise is that human space exploration must be highly efficient, cost effective, and autonomous as placing humans beyond low Earth orbit is fraught with political… read more
