Low-cost medical and security cameras could be possible in the future thanks to a new multispectral light sensor developed by University of Surrey researchers. The sensor can detect the full spectrum of light, from ultraviolet (UV) to visible and near-infrared light.

“Until now … multiple sensors were required to measure different ranges of the light spectrum, significantly increasing cost,” said lead researcher Richard Curry, PhD. from the… read more

Hacking Higher Ed

U of People

How much would it cost to educate all those currently priced out of education? “Realistically, only a drop in the bucket in relation to the billions floating within the higher education industry,” says Shai Reshef, founder and president of University of the People, a free, non-profit, online university.

Reshef joined five other guests on Radio Open Source, a weekly WBUR radio program produced by… read more

Using mechanisms adopted by birds, bats, insects and snakes, 14 research teams have developed ideas for improving drone-flying performance in complex urban environments.

The research teams presented their work May 23 in a special open-access issue of IOP Publishing’s journal Bioinspiration and Biomimetics devoted to bio-inspired flight control. Here are a few examples.

An algorithm developed by Hungarian researchers allows multiple drones… read more

EPFL scientists have developed LEGO-like adaptive robotic modules called “Roombots” that can change their shape to create reconfigurable, movable furniture and objects.

Like LEGO bricks, Roombots can be stacked upon each other to create various structures and combined with furniture and other objects, changing shape and functionality during the day as needed.

“It could be very useful for disabled individuals to be able to ask objects… read more

‘Thermal Touch’ will turn any surface into an AR touch screen

"Thermal Touch" makes any surface or object touchable (credit: Metaio)

Metaio (as in meta I/O) has developed a prototype of a system called  “Thermal Touch” that the Germany-based company says would allow a user of a future wearable headset to make any object touchable.

The prototype system combines a thermal infrared and standard camera connected to a tablet PC (in the future, Metaio assumes, these cameras would be built into augmented reality (AR) glasses).

The system… read more

Would you eat ‘eco-friendly’ meat created from stem cells?

May 23, 2014

cells to food

In a paper in the Cell Press journal Trends in Biotechnology, Cor van der Weele of Wageningen University in The Netherlands and coauthor Johannes Tramper describe a potential meat manufacturing process, starting with a vial of cells taken from a cell bank and ending with a pressed cake of minced meat.

Cor van der Weele  point out that the rising demand for meat around the world is… read more

New research at the Linus Pauling Institute at Oregon State University suggests a fix for serious side effects of rapamycin*, a drug that appears to mimic the ability of dietary restriction to slow the aging process.

Laboratory mice that have received rapamycin have reduced the age-dependent decline in spontaneous activity, demonstrated more fitness, improved cognition and cardiovascular health, had less cancer, and lived substantially longer than… read more

The Presidential Commission for the Study of Bioethical Issues (Bioethics Commission) has released volume one of its two-part response to President Obama’s request related to the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, entitled Gray Matters: Integrative Approaches for Neuroscience, Ethics, and Society.

“Neuroscience has begun to make important breakthroughs, but given the complexity of the brain, we must better understand it in order to make desired… read more

The biomechanics behind amazing ant strength

Could help design better exoskeletons for humans and robot joints
May 21, 2014

How can an ant lift objects many times heavier than its own body? Engineers at The Ohio State University combined computational modeling at the Ohio Supercomputer Center (OSC) and lab experiments to find out.

They focused on the ant’s neck — the single joint of soft tissue that bridges the stiff exoskeleton of the ant’s head and thorax. When an ant carries food or any other object,… read more

World’s smallest, fastest nanomotor

Researchers at The University of Texas at Austin have built the “smallest, fastest, and longest-running” nanomotor  to date — an important step toward developing miniature machines that could one day move through the body to deliver drugs such as insulin for diabetics when needed, or target and treat cancer cells without harming good cells, the scientists say.

Led by Cockrell School of Engineering mechanical engineering assistant… read more

Glasses-free 3D projector

New design could also make conventional 2D video higher in resolution and contrast
May 20, 2014

llustration of concept. A light field projector, build using readily-available optics and electronics, emits a 4D light field onto a screen that expands the field of view so that observers on the other side of the screen can enjoy glasses-free 3D entertainment. No mechanically moving parts are used in either the projector or the screen. Additionally, the screen is completely passive, potentially allowing for the system to be scaled to significantly larger dimensions. (Credit: MIT Media Lab, Camera Culture Group)

Over the past three years, researchers in the Camera Culture group at the MIT Media Lab have steadily refined a design for a glasses-free, multiperspective, 3D video screen, which they hope could provide a cheaper, more practical alternative to holographic video in the short term.

Now they’ve designed a projector that exploits this technology, which they’ll unveil at this year’s… read more

A new way to beam power to medical chips deep inside the body

Wireless system uses the same power as a cell phone to safely transmit energy to chips, paving the way for new "electroceutical" devices to treat illness or alleviate pain

Imperial College London physicists have discovered how to create matter from light — a feat thought impossible when the idea was first theorized by scientists G. Breit and J. Wheeler in 1934.

Breit and Wheeler suggested that it should be possible to turn light into matter by smashing together only two particles of light (photons), to create an electron and a positron — the simplest method of… read more
