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
A Trinity College Dublin chemistry professor has been awarded a €2.5 million ($3.2 million) research grant by the European Research Council (ERC) to continue research into nanowire networks.
Professor John Boland, Director of CRANN, a nanoscience institute, and a Professor in the School of Chemistry, said the research could result in computer networks that mimic the functions of the human brain and vastly improve… read more
Google Ventures is launching a new initiative to fuel the development of Google Glass called Glass Collective, in partnership with venture capital firms Andreessen Horowitz and Kleiner Perkins Caufield & Byers, Forbes reports.
The three firms hope to fund a community of developers to make Google Glass the next major computing platform.
Marc Andreessen of Andreessen Horowitz said Glass would become a platform… read more
Researchers at the Institute for Quantum Optics and Quantum Information in Austria and the European Space Agency have proposed using the International Space Station (ISS) to test the limits of “spooky action at a distance” (remote quantum entanglement) and potentially help to develop the first global quantum communication network.
Albert Einstein famously described quantum entanglement as “spooky action at distance”; however, up until now, experiments… read more
