On a first date, couples scrutinize each other’s facial expressions for a clue as to whether the date will turn into a long-term relationship. Game publishers and designers might start doing the same thing.
By analyzing the movements of gamers’ smile and frown muscles in the first 45 minutes of play, Taiwanese researchers have found a way to predict a game’s addictiveness, reports IEEE Spectrum.

Here is the plan. Customize several Gulfstream business jets with military engines and with equipment to produce and disperse fine droplets of sulfuric acid. Fly the jets up around 20 kilometers-significantly higher than the cruising altitude for a commercial jetliner but still well within their range. At that altitude in the tropics, the aircraft are in the lower stratosphere, reports MIT Technology Review.
The planes spray the… read more
A University of Innsbruck research team has directly transferred the quantum information stored in an atom onto a particle of light for the first time.
Background
Thanks to the strange laws of quantum mechanics, quantum computers would be able to carry out certain computational tasks much faster than conventional computers. Among the most promising technologies for the construction of a quantum computer are… read more
A new drug designed to prevent the early stages of Alzheimer’s disease could enter clinical trials in a few years’ time, according to scientists.
Alzheimer’s disease begins when a protein called amyloid-β (Aβ) starts to clump together in senile plaques in the brain, damaging nerve cells and leading to memory loss and confusion.
Professor David Allsop and Dr Mark Taylor at Lancaster University have… read more
Researchers from the University of Bordeaux in France used high-frequency sound waves to test the stiffness and viscosity of the nuclei of individual human cells to help answer questions such as how cells adhere to medical implants and why healthy cells turn cancerous.
“We have developed a new non-contact, non-invasive tool to measure the mechanical properties of cells at the sub-cell scale,” says Bertrand Audoin, a professor… read more
Get ready for four-legged bots of all shapes and sizes — and for all sorts of uses — that learn how to maneuver through landscapes with the grace of a cheetah, Fast Company reports.
The most nightmare-inducing characteristic of Big Dog, DARPA’s robotic military mule, might be the way it moves so stiffly, yet unrelentingly, over treacherous battleground. Turns out the repetitive mechanical gait that… read more
Mice can recover from physically debilitating strokes that damage the primary motor cortex, the region of the brain that controls most movement in the body if the mice are quickly subjected to physical conditioning that rapidly “rewires” a different part of the brain to take over lost function, Johns Hopkins researchers have found. The research uses precise, intense and early treatment.… read more
Engineers and physicists are developing acoustic versions of metamaterials that steer sound, which could be used to steer seismic waves around high-value buildings such as nuclear power stations or airports.
The Institut Fresnel in Marseille and the ground improvement specialist company, Menard, both in France, say they’ve built and tested a seismic invisibility cloak in an alluvial basin in southern France, MIT Technology Review reports.

Six percent of red-dwarf stars have habitable, Earth-sized planets, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found.
Red dwarfs are the most common stars in our galaxy; about 75 percent of the closest stars are red dwarfs. The closest Earth-like planet could be just 13 light-years away, Harvard astronomer and lead author Courtney Dressing calculated.
“We thought we would have to search… read more
Drones are no longer the sole domain of the military, and just as with many new technologies, they can easily fall into the wrong hands, global security advisor, writer and consultant Marc Goodman reports in Time.
Criminal organizations are early adopters of technology, and some have already used UAVs and other forms of robotics to violate the law… read more
For the past few months, some of the world’s leading cryptographers have been keeping a closely guarded secret about a pioneering new invention. Today, they’ve decided it’s time to tell all, Slate Future Tense reports.
Back in October, the startup tech firm Silent Circle ruffled governments’ feathers with a “surveillance-proof” smartphone app to allow people to make secure phone calls and send texts… read more
Using lasers, a research team at the Vienna University of Technology is developing microstructures for embedding living cells.
The process allows living cells to be incorporated into intricate custom structures, similar to biological tissue, in which cells are surrounded by the cell’s normal extracellular matrix.
This technology is particularly important for artificially growing biotissue, for finding new drugs, or for stem cell research.… read more
A new 3D printing process using human stem cells could pave the way to custom replacement organs for patients, eliminating the need for organ donation and immune suppression, and solving the problem of transplant rejection.
The process, developed at Edinburgh-based Heriot-Watt University, in partnership with Roslin Cellab, could also speed up and improve the process of reliable, animal-free drug testing by growing three-dimensional human tissues and structures… read more
UC Irvine neuroscientists have developed a way to stop epileptic seizures with fiber-optic light signals, heralding a novel opportunity to treat the most severe manifestations of the brain disorder.
Using a mouse model of temporal lobe epilepsy, Ivan Soltesz, Chancellor’s Professor and chair of anatomy & neurobiology, and colleagues created an EEG-based brain-waves-sensing) computer system that lights up hair-thin fiber optic… read more
Salk Institute for Biological Studies researchers have shared a how-to secret for biologists: code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images.
The method promises to speed research into the underlying causes of disease by making single-molecule microscopy of practical use for more laboratories.
“This is an extremely cost-effective way for labs to process super-resolution images,” says … read more
