The European Union predicts that electric vehicles (EV) could be in mass production by 2020. But what might be their impacts, such as new demands on electrical distribution grids and on how and where we travel?
It has… read more
Computer scientists at Saarland University and Carnegie Mellon University are studying the potential use of the human body as a touch sensitive surface for controlling mobile devices. They have developed flexible silicone rubber stickers with pressure-sensitive sensors that fit snugly to the skin.
By operating these touch input stickers, users can use their own body to control mobile devices. Because of the flexible material used, the sensors can be… read more
Scientists of the University of Luxembourg and of the Japanese electronics company TDK have extended sensitivity of a conductive oxide film used in solar cells in the near-infrared region to use more energy of the sun and thus create higher current.
Similar attempts have been made before, but this is the first time that these films were prepared by a one-step process and, at the same time, stable in… read more
In tests involving half of the catalytic reaction that takes place in fuel cells, a team led by materials scientist Pulickel Ajayan and chemist James Tou discovered that versions with about 10 percent boron and nitrogen were efficient in catalyzing an… read more
University of Minnesota researchers have found that an ultrathin black phosphorus film — only 20 layers of atoms — allows for high-speed data communication on nanoscale optical circuits. Black phosphorus is a crystaline form of the element phosphorus.
The devices showed vast improvement in efficiency over comparable devices using graphene.
The work by University of Minnesota Department of Electrical and Computer Engineering Professors Mo Li and Steven Koester… read more
Roboticist and aerospace engineer Julie Shah and her team at MIT are developing next-generation assembly line robots that are smarter and more adaptable than robots available on today’s assembly lines.
The team is designing the robots with artificial intelligence that enables them to learn from experience, so the robots will be more responsive to human behavior. The more robots can sense the humans around them and make adjustments,… read more
By measuring a series of diffraction pattern from a virus injected into an XFEL beam, researchers at Stanford’s Linac Coherent Light Source (LCLS) have determined the first three-dimensional structure of a virus, using a mimivirus.
X-ray crystallography has solved the vast majority of the structures of proteins and other biomolecules. The success of the method relies on growing large crystals of the molecules, which isn’t possible… read more
Computer chips’ clocks have stopped getting faster, so chipmakers are instead giving chips more cores, which can execute computations in parallel.
Now, in simulations involving a 64-core chip, MIT computer scientists have improved a system that cleverly distributes data around multicore chips’ memory banks — increasing system computational speeds by 46 percent while reducing power consumption by 36 percent.
“Now that the way to improve performance is… read more
Researchers at Queen’s University Belfast, the University of Manchester, and the STFC Daresbury Laboratory are developing new software to increase the ability of supercomputers to process big data faster while minimizing increases in power consumption.
To do that, computer scientists in the Scalable, Energy-Efficient, Resilient and Transparent Software Adaptation (SERT) project are using “approximate computing” (also known as “significance-based computing”) — a form… read more
Jürgen Schmidhuber, Director of the Swiss Artificial Intelligence Lab (IDSIA), will do an AMA (Ask Me Anything) on reddit/r/MachineLearning on Wednesday March 4, 2015 at 10 AM EST. You can post questions now in advance in this thread.
A prototype “quantum radar” that has the potential to detect objects that are invisible to conventional systems has been developed by an international research team led by a quantum information scientist at the University of York.
The new breed of radar is a hybrid system that uses quantum correlation between microwave and optical beams to detect objects of low reflectivity such as cancer cells or aircraft with a stealth… read more
USC scientists may have discovered a family of superconductor materials called superatoms that could lead to room-temperature supercomputers.
A team led by Vitaly Kresin, professor of physics at the USC Dornsife College of Letters, Arts and Sciences, found that aluminum “superatoms” — homogenous clusters of atoms — appear to form Cooper pairs of electrons (one of the key elements of superconductivity) at temperatures around 100 Kelvin.
Though 100… read more
Cruising through the asteroid belt, NASA Dawn spacecraft is approaching dwarf planet Ceres, and some puzzling features are coming into focus, revealing craters and mysterious bright spots.
“We expected to be surprised by Ceres,” says Chris Russell, principal investigator of the Dawn mission, based at UCLA. “We did not expect to be this puzzled. … As Dawn has come closer to Ceres, the bright spots have become brighter and… read more
A small area of the brain called the anterior cingulate cortex (ACC) in the thalamus can be optically stimulated to control pain, University of Texas at Arlington scientists have found.
The researchers used optogenetic stimulation with a blue laser to control pain sensation in a mouse, created by a chemical irritant (formalin) and mechanical pain, such as that experienced following a pinprick or pinch.
“Our results… read more
