A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team.
The new plastic also has other potential uses, including optical uses.
The team has successfully used the new plastic to make lithium-sulfur batteries.
Next-generation lithium-sulfur, or Li-S, batteries based on the plastic will be better for electric and… read more
A new, minimally invasive treatment that creates microscopic holes in tumors without harming healthy tissue is a promising treatment for challenging cancers, suggests a preliminary study being presented at the Society of Interventional Radiology‘s 38th Annual Scientific Meeting in New Orleans.
“Irreversible electroporation (or IRE) is a new way to attack cancer, using microsecond electrical pulses to kill cancer at the cellular level… read more
To improve brain mapping, a group of French scientists have produced the world’s first biocompatible microscopic organic transistors that can amplify and record signals directly from the surface of the brain, building on prototypes developed at the Cornell NanoScale Science and Technology Facility (CNF).
This is the first in vivo use of transistor arrays to record brain activity directly on the surface of the cortex… read more
New research from the University of Copenhagen combines formal philosophy, social psychology, and decision theory to understand and tackle these phenomena.
“Group behavior that encourages us to make decisions based on false beliefs has always existed.
However, with the advent of the Internet and social media, this kind of behavior is more likely to occur than ever, and on a much larger scale, with… read more
Researchers at Washington University School of Medicine in St. Louis and the University of Illinois at Urbana-Champaign have developed tiny devices containing light-emitting diodes (LEDs) the size of individual neurons that activate brain cells with light.
“This strategy should allow us to identify and map brain circuits involved in complex behaviors related to sleep, depression, addiction, and anxiety,” says co-principal investigator Michael R. Bruchas, PhD, assistant… read more
German artist Martin Missfeldt has created an infographic that attempts to show how Google Glass works, based on various sources (listed below). One correction: an image is actually not projected directly onto the retina; it is refracted by the cornea and focused by the lens.
A technique that uses light-activated proteins to stimulate particular brain cells and positron emission tomography (PET) scans to trace their effects throughout the entire brain of fully-awake, moving animals has been developed by U.S. Department of Energy’s Brookhaven National Laboratory
The method will allow researchers to map exactly which downstream neurological pathways are activated or deactivated by stimulation of targeted brain regions, and how that brain activity… read more
In a paper published online in the journal ACS Nano, Joshua Goldberger, assistant professor of chemistry at Ohio State University, and colleagues describe how they created a stable, one-atom-thick single layer of germanium atoms.
In this form, the crystalline material is called germanane.
The chemists found that it conducts electrons more than ten times faster than silicon and five times faster than conventional germanium — the same material that… read more
An advance in micromotor technology is opening the door to broad new medical and industrial uses for these tiny devices, scientists said the national American Chemical Society meeting this week.
Akin to the invention of cars that fuel themselves from the pavement or air, rather than gasoline or batteries,
Joseph Wang, D.Sc., who leads research on the motors, said that efforts to build minute,… read more
Commercial laser printers typically produce pin-sharp images with spots of ink about 20 micrometers apart, resulting in a resolution of 1,200 dots per inch (dpi).
By shrinking the separation to just 250 nanometers — 80 times smaller, a research team at A*STAR can now print images at an incredible 100,000 dpi, the highest possible resolution for a color image.
These images could be used… read more
A new assessment by the Pentagon’s intelligence arm has concluded for the first time, with “moderate confidence,” that North Korea has learned how to make a nuclear weapon small enough to be delivered by a ballistic missile, according to The New York Times Thursday.
But late Thursday, the director of national intelligence, James R. Clapper Jr., released a statement saying that the assessment did not represent a consensus of… read more
A team of researchers has released survey results that reveal the habits of San Diego County drivers who use their cell phone while behind the wheel — currently the leading cause of driver distraction crashes in California.
“Studies have shown that phoning and driving increases the risk of crashes four-fold, with hands-free and handheld devices equally dangerous; this is the same as driving with a blood alcohol… read more
As part of the new BRAIN research initiative, DARPA plans $50 million in 2014 investments to increase understanding of brain function and create new capabilities.
DARPA plans to explore two key areas to elicit further understanding of the brain. New tools are needed to measure and analyze electrical signals and the biomolecular dynamics underpinning brain function. Researchers will also explore, abstract and model the… read more
In a development that could make the advanced form of secure communications known as quantum cryptography more practical, University of Michigan researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques.
Single-photon emitters release one particle of light, or photon, at a time, as opposed to devices like lasers that release a stream of them.
Single-photon… read more
A “sonic lasso” that can grip microscopic objects, such as cells, and move them around has been demonstrated by researchers at the University of Bristol’s Department of Mechanical Engineering and University of Dundee’s Institute for Medical Science and Technology.
The cells and other small objects are trapped by a spinning ultrasonic vortex, which acts as a lasso that can be controlled and moved.… read more
