Astronomers have used light echoes as a time machine to unearth secrets of one of the most influential events in the history of astronomy — a stellar explosion witnessed on Earth more than 400 years ago. By using a Galactic cloud as interstellar “mirror,” astronomers have now re-analyzed the same light seen on Earth in [...]

It is a well-known fact in drug trials that individuals can respond just as well to placebos, sugar pills, as to the active drug. On the other hand, it is difficult to explain why only certain people get better from placebos. Researchers have now found gene variants that can impact the placebo effect and a [...]

Gene Required For Radiation-induced Protective Pigmentation Also Promotes Survival Of Melanoma Cells
Scientists have new insight into the response of human skin to radiation and what drives the most aggressive and deadly form of skin cancer. The research may be useful in the design of new strategies for prevention of malignant melanoma.
New ways of squeezing out greater efficiency from solar photovoltaic cells are emerging from computer simulations and lab tests conducted by a team of physicists and engineers.
Researchers are developing a computer image processing system that detects and classifies human facial expressions. The aim of this system is to take and analyze photos of individuals, potentially in areas of high traffic where security is a primary concern, such as an airport.

Astrophysicists agree that the best method for avoiding a catastrophic collision would be to change the path of the asteroid heading toward our planet. But to do that, scientists need to be able to predict what would happen if they attempted an explosion.
Continuous positive airway pressure treatment seems to improve cognitive functioning in patients with Alzheimer’s disease who also suffer from obstructive sleep apnea, according to the results of a randomized clinical trial.

Research chemists have devised an elegant process which simply and cheaply covers small particles of polymer with a layer of silica-based nanoparticles. The final result provides a highly versatile material that can be used to create a range of high performance materials such as: self healing paints, and clever packaging that can be tailored to [...]
Screening for a panel of gene variants associated with the risk for type 2 diabetes can identify adults at risk for the disorder but is not significantly better than assessment based on traditional risk factors such as weight, blood pressure and blood sugar levels.
