Researchers in the voice, speech, and language branch of the National Institute on Deafness and Other Communication Disorders (NIDCD) at the National Institutes of Health (NIH) have used functional magnetic resonance imaging to study the brain activity of rappers when they are “freestyling” — spontaneously improvising lyrics in real time.

Published online in the November 15 issue of the journal Scientific Reports (open access), the findings… read more

There is no centralized system to monitor and report changes in the Earth’s life-support systems. So scientists in 77 nations have established the Group on Earth Observations (GEO) and the Group on Earth Observation Biodiversity Observation Network (GEO BON), which integrates existing data streams into one platform to provide a  global warning system for Earth’s… read more

How to create an animated character from your facial expressions in real time

An avatar reproduces your facial expressions in real time. You move, it moves. You smile, it smiles.
November 20, 2012

faceshift

Faceshift, announced Monday, is software that uses Kinect and similar cameras to read your face and create a moving avatar from it. It could enhance the future of video games and make video chats more fun, says Thibaut Weise, founder of Faceshift, a spinoff of EPFL’s Computer Graphics and Geometry Laboratory.

The software needs only ten minutes to recognize your face as you create basic expressions requested by the program:… read more

Northwestern Medicine researchers have developed a biodegradable nanoparticle  that stealthily delivers an antigen that tricks the immune system into stopping its attack on myelin and haltd a model of relapsing remitting multiple sclerosis (MS) in mice, according to new research.

The nanoparticles can also be applied to other immune-mediated diseases, including Type 1 diabetes, food allergies, and asthma.

Optogenetics illuminates pathways of motivation and depression through brain

November 20, 2012

optogenetic fluorescence

Karl Deisseroth, MD, PhD, a professor of bioengineering and of psychiatry and behavioral sciences at Stanford University, and postdoctoral scholar Melissa Warden, PhD, have isolated the neurons that carry the split-second decisions to act, from the higher brain to the brain stem. In doing so, they have provided insight into the causes of severe brain disorders such as depression.

A new fiber-optic device created by MIT biologists and engineers is the first tool that can deliver 1000 precise points of light to a 3D section of living brain tissue matter smaller than a sugar cube.

This is a step forward for a technique called optogenetics, which uses gene treatments to turn individual brain cells on and off with light.

Scientists can use this new 3D… read more

Rice unveils super-efficient solar-energy technology

November 21, 2012

The solar steam device developed at Rice University has an overall energy efficiency of 24 percent, far surpassing that of photovoltaic solar panels. It may first be used in sanitation and water-purification applications in the developing world. (Credit: Jeff Fitlow/Rice University)

Rice University scientists have unveiled a revolutionary new technology that uses silicon dioxide/gold nanoshells and N115 carbon nanoparticles to convert solar energy directly into steam. The new “solar steam” method from Rice’s Laboratory for Nanophotonics (LANP) is so effective it can even produce steam from icy cold water.

The technology has an overall energy efficiency of 24 percent. Photovoltaic solar panels, by comparison, typically have… read more
