Scientists at the California Institute of Technology have created a remote-controlled robot that is able to simulate the “visual” experience of a blind person who has been implanted with a visual prosthesis, such as an artificial retina using a silicon chip with electrodes that directly stimulate retinal nerve cells. The system allows for testing new prosthetic technologies.

Aircraft or submarines covered with an undulating skin able to change at a flick of a button would experience 50% less drag than conventional vehicles.
This trick, which naturally occurs in dolphins, is now being tested by engineers at Texas A&M University.

Three research teams announced new developments in producing relativistic electron beams using laser-produced plasmas to accelerate the beams.
The beams have a narrow energy spread and are focusable. These new developments could help to shrink the size and cost of future particle accelerators for fundamental physics experiments and applications in materials and biomedicine. Laser electron accelerators could eventually fit into a university basement.
All three research teams published… read more

Researchers from the University of California, San Diego have developed the “Whole Brain Catalog,” a repository for data gathered about the mouse brain.

NASA’s Upper Atmosphere Research Satellite is expected to crash to Earth Sept. 23, plus or minus a day, as of the latest NASA update, Sept. 18.
NASA says the 35-foot-long satellite will crash somewhere between 57 degrees north latitude and 57 degrees south latitude — a projected crash zone that covers most of the planet. Although the spacecraft will break into pieces during re-entry, not all of it… read more

In the distant future, it might be possible to develop complex software to decode alien languages, says Linguist and anthropologist Terrence Deacon of the University of California believes.
He argues that no matter how abstract a symbol becomes, it is still somehow grounded in physical reality, and that limits the number of relationships it can have with other symbol words. In turn, this defines the grammatical structure that emerges… read more

Princeton scientists have invented a fast and reliable method for identifying alterations to chromosomes that occur when cells become malignant. It quickly analyzes an entire genome and produces a reliable list of chromosome sections that have been either deleted or added.
The technique helps to show how cells modify their own genetic makeup and may allow cancer treatments to be tailored more precisely to a patient’s disease.… read more

Complete Genomics has sequenced three human genomes for an average cost of $4,400.
Lowering the cost of sequencing would allow scientists to study large numbers of human genomes, which is now thought necessary to understand the genetic basis of complex disease.

Researchers at Oak Ridge National Laboratory (ORNL) have discovered a material that has 10 times the piezoelectric effect of crystals and ceramics, making it suitable for perhaps hundreds of everyday uses.
ORNL’s Volker Urban and colleagues at Technical University Aachen in Germany noticed the reverse piezoelectric effect (creating a mechanical strain by applying an electrical voltage) while conducting fundamental research on polymers.… read more

Researchers from the University of California Santa Cruz have developed the idea of Pergamum, a new disk-based approach for archiving data.
Pergamum uses both intra-disk and inter-disk redundancy to guard against data loss, relying on hash tree-like structures of algebraic signatures to efficiently verify the correctness of stored data.
They believe a 10 petabytes storage system could be built for about $4700, with an annual operational cost (power… read more

Mice born without large portions of their “junk DNA” seem to survive normally. The result contradicts the beliefs of many scientists who have sought to uncover the function of these parts of the genome.
David Haussler of the University of California, Santa Cruz, who has investigated why genetic regions are conserved, believes that non-coding regions may have an effect too subtle to be picked up in the tests to… read more

The latest in immersive media, 3D domes, neurofeedback art, virtual worlds and other cutting-edge media formats and their potential as tools for transformation will be explored at IMMERSE IN THE FUTURE: A VISIONARY EVENING OF ARTS, MEDIA AND ENTERTAINMENT IN THE 21ST CENTURY, Monday, November 16th in Los Angeles and in Second Life.
The event will include presentations by the LA Opera; Kathy Eldon, Founder of Creative Visions Foundation;… read more

In a discovery that challenges conventional wisdom on the brain mechanisms of learning, UCLA neuro-physicists have found there is an optimal brain “rhythm,” or frequency, for changing synaptic strength, and each synapse is tuned to a different optimal frequency for learning.
“Our work suggests that some problems with learning and memory are caused by synapses not being tuned to the right frequency,” said Mayank R.… read more

Some food dyes exert an anti-cancer effect in fish, Oregon State University scientists have found.

Rice University’s Center for Biological and Environmental Nanotechnology (CBEN) today announced the formation of the International Council on Nanotechnology (ICON), a collaboration among academic, industry, regulatory and non-governmental interest groups that will work to assess, communicate, and reduce potential environmental and health risks associated with nanotechnology.
