The Swiss Commission for Technology and Innovation has awarded scientists a $2.4 million (2.25 million CHF) grant to develop an affordable photovoltaic system capable of concentrating solar radiation 2,000 times and converting 80 percent of the incoming radiation into useful energy.*
The system would also provide desalinated water and cool air in sunny, remote locations where they are often in short supply.
The prototype HCPVT system… read more
In February, KurzweilAI introduced “temporary electronic tattoos,” which are foldable, stretchable electrode arrays that can non-invasively measure neural (EEG) signals. Now. researchers led by Todd Coleman at the University of California, San Diego, have now optimized the placement of the electrodes to pick up more complex brainwaves, New Scientist reports.
The researchers demonstrated this by monitoring P300 signals in the forebrain. These appear when… read more
What causes a cell to metastasize into a cancerous tumor? To find out, Corey Neu, an assistant professor in Purdue University‘s Weldon School of Biomedical Engineering, and colleagues have combined an atomic force microscope (AFM) and a nuclear magnetic resonance system.
An AFM uses a tiny vibrating probe called a cantilever with a tip that travels over the surface of a… read more
By using computer-aided drug discovery, an Ohio State University molecular biochemist and molecular imaging chemist are collaborating to create an imaging chemical that attaches predominantly to tau-bearing lesions in living brain.
Their hope is that the “designer” tracer will open the door for earlier diagnosis — and better treatments for Alzheimer’s, frontal temporal dementia and traumatic brain injuries like those suffered by professional athletes, all… read more
Researchers at Northeastern University in Boston have developed a gene therapy approach that may one day stop Parkinson’s disease (PD) in it tracks, preventing disease progression and reversing its symptoms.
The novelty of the approach lies in the nasal route of administration and nanoparticles containing a gene capable of rescuing dying neurons in the brain.
Parkinson’s is a devastating neurodegenerative disorder caused… read more
The first known method to permanently bypass the blood-brain barrier*, using mucosa, or the lining of the nose, has been demonstrated by researchers in the department of Otology and Laryngology at the Massachusetts Eye and Ear/Harvard Medical School and the Biomedical Engineering Department of Boston University.
The method opens the door to new treatment options for those with neurodegenerative and CNS disease.… read more
University of Nebraska-Lincoln materials engineers have developed a structural nanofiber that is both strong and tough, a discovery that could transform everything from airplanes and bridges to body armor and bicycles.
“Whatever is made of composites can benefit from our nanofibers,” said the team’s leader, Yuris Dzenis, McBroom Professor of Mechanical and Materials Engineering and a member of UNL’s Nebraska Center for Materials and Nanoscience.… read more
Biologists at UC San Diego have identified eight genes never before suspected to play a role in wound healing that are called into action near the areas where wounds occur.
Their discovery, detailed this week in the open-access journal PLOS ONE (open access), was made in the laboratory fruit fly Drosophila. But the biologists say many of the same genes that regulate biological processes in the… read more
Researchers at the HarvardSchool of Engineering and Applied Sciences (SEAS) have developed an inexpensive but sensitove tactile sensor for robotic hands.
Designed by researchers in the Harvard Biorobotics Laboratory at SEAS, the sensor, called TakkTile, is intended to put what would normally be a high-end technology within the grasp of commercial inventors, teachers, and robotics enthusiasts.
TakkTile takes… read more
Researchers at the Harvard Stem Cell Institute (HSCI) have discovered a hormone that holds promise for a dramatically more effective treatment of type 2 diabetes, a metabolic illness afflicting an estimated 26 million Americans.
The researchers believe that the hormone might also have… read more
Dr. Dmitry Itskov, founder of the 2045 Initiative and Global Future 2045 congress (GF2045), announced Thursday that he will unveil Dr. David Hanson’s latest android, the Dmitry Avatar-A head — the “world’s most human-like android head” — at the GF2045 congress, scheduled for June 15–16 at Lincoln Center in New York City.
The new android, a robotic replica of Itskov’s head, is being created by… read more
A doctor says people can be revived several hours after they have seemingly died, BBC News reports. Should this change the way we think about death?
“While 45 minutes is absolutely remarkable and a lot of people would have written her off, we now know there are people who have been brought back, three, four, five hours after they’ve died and have led remarkably good quality lives,”… read more
Lab-grown livers have come a step closer to reality thanks to a 3D printer loaded with cells, New Scientist reports.
Created by Organovo in San Diego, California, future versions of the system could produce chunks of liver for transplant.
The mini-livers that Organovo made are just half a millimeter deep and 4 millimeters across but can perform most functions of the real thing.… read more
Today’s Internet runs on linked silicon chips, but a future quantum version might be built from diamond crystals, Nature News reports.
Physicists report in Nature that they have entangled information kept in pieces of diamond 3 meters apart, so that measuring the state of one quantum bit (qubit) instantly fixes the state of the other — a necessary step for exchanging quantum information over large distances.… read more
Two European Physical Journal D papers challenge established wisdom about the nature of vacuum.
In one paper, Marcel Urban from the University of Paris-Sud and colleagues identified a quantum-level mechanism for interpreting vacuum as being filled with pairs of virtual particles with fluctuating energy values.
As a result, the inherent characteristics of vacuum, such as the speed of light, may not be a constant… read more
