- Why There May Never Be A Cure for Ebola — The Wire 8/1/2014
- Why we don’t have an ebola vaccine yet: cases are so rare, drug makers haven’t been interested in investing. NIH’s Ebola vaccine has been studied in monkeys and
A biomaterial that can regenerate damaged skeletal muscle is being developed by University of Arkansas biomedical engineering researcher Jeffrey Wolchok, funded by a National Institutes of Health three-year, $437,248 grant.
Living cells secrete fibrous proteins and polysaccharide gels called extracellular matrix, which support cell survival and tissue strength. Minor muscle injuries affect tissue cells but not the extracellular components. In severe injuries, however, the extracellular matrix does not… read more
Scientists at Brookhaven National Laboratory have discovered a new catalytic system for converting carbon dioxide (CO2) to methanol — a key commodity used to create a wide range of industrial chemicals and fuels. With significantly higher activity than other catalysts now in use, the new system could make it easier to get normally unreactive CO2 to participate in these reactions.
“Developing an effective catalyst for synthesizing methanol… read more
CrowdOptic is working with the Department of Cardiothoracic Surgery at Stanford University Medical Center to use CrowdOptic’s Google Glass software to help improve resident training in complex surgical procedures, the company has announced.
CrowdOptic’s app gives a Google Glass wearer — such as a surgeon — access to what another user — such as a resident performing an operation — is seeing, simply by looking in the… read more
By studying the injuries and aptitudes of Vietnam War veterans who suffered penetrating head wounds during the war, researchers have found that brain regions that contribute to optimal social functioning are also vital to general intelligence and emotional intelligence.
This finding, reported in the journal Brain, bolsters the view that general intelligence emerges from the emotional and social context of one’s life.
“We are trying to understand the nature… read more
The new nanocarriers are just 15 nanometers in diameter, based on building blocks called amphiphilic polymers: they have both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties). That allows the nanocarriers to hold the… read more
An international team of researchers led by the University of Arizona (UA) has sequenced the complete genome of African rice.
The genetic information will enhance scientists’ and agriculturalists’ understanding of the growing patterns of African rice, and help development of new rice varieties that are better able to cope with increasing environmental stressors to help solve global hunger challenges, the researchers say.
The research paper was… read more
Israeli and German researchers have created a nanoscale screw-shaped propeller that can move in a gel-like fluid, mimicking the environment inside a living organism, as described in a paper published in the June 2014 issue of ACS Nano.
The… read more
Brain responses of just a few individuals are a remarkably strong predictor of response to future products and messages, according to a study conducted at the City College of New York (CCNY) and Georgia Tech.
By analyzing the brainwaves of just 16 individuals as they watched mainstream television content, the researchers were able to accurately predict the preferences of large TV audiences — up to… read more
UC Berkeley and MIT researchers have developed a prototype of a simple vision-correcting display (and associated algorithm) that uses a printed pinhole screen sandwiched between two layers of clear plastic attached to an iPod display to enhance image sharpness.
The tiny pinholes are 75 microns (millionths of a meter) each and spaced 390 microns apart.
The algorithm adjusts the intensity of each direction of light that emanates from… read more
Several DARPA programs are exploring innovative technologies and approaches that could supplement GPS to provide reliable, highly accurate real-time positioning, navigation and timing (PNT) data for military and civilian uses and deal with possible loss of GPS accuracy from solar storms or jamming, for example.
DARPA Director Arati Prabhakar said DARPA currently has five programs that focus on PNT-related technology.
In a study published July 28 in the Proceedings of the National Academy of Sciences, Salk Institute for Biological Sciences researchers have found that brain cells called astrocytes — not neurons — can control the brain’s gamma waves.
Researchers at NASA‘s Jet Propulsion Laboratory (JPL), California Institute of Technology, and Pennsylvania State University have developed a 3D printing process that transitions from one metal or alloy to another in a single object.
For example, they created a prototype of an improved telescope mirror mount. The part at the top near the glass mirror is made of a metal with low… read more
Nuance Communications, Inc. announced today an annual competition to develop programs that can solve the Winograd Schema Challenge, an alternative to the Turing test that provides a more accurate measure of genuine machine intelligence, according to its developer, Hector Levesque, Professor of Computer Science at the University of Toronto, and winner of the 2013 IJCAI Award for Research Excellence.
Nuance is sponsoring the yearly… read more
A new study led by MIT materials scientists reveals the reason why gold nanoparticles can easily slip through cell membranes to deliver drugs directly to target cells.
The nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons.
In the July 21 issue of Nature Communications, the researchers describe in detail the mechanism… read more
