Materials exposed to a high-radiation environment such as the inside of a nuclear reactor vessel can gradually degrade and weaken. But to determine exactly how much damage these materials suffer generally requires removing a sample and testing it in specialized...

Researchers at the New York Institute of Technology (NYIT; New York, NY) have developed computer simulations showing how lasers attack oral bacterial colonies, suggesting that benefits of using lasers in oral debridement include killing bacteria and promoting better dental health....

Psychiatric disorders are a major public health concern. While the development of neuroleptics and antidepressants has led to significant improvements in patients’ conditions, available treatments remain largely insufficient and unsatisfactory. Advances in the field are hindered by a shortage of...

Scientists hoping to get a glimpse of molecules that control brain activity have devised a new probe that allows them to image these molecules without using any chemical or radioactive labels. Read more...

Researchers led by EPFL have built ultra-high quality optical cavities for the elusive mid-infrared spectral region, paving the way for new chemical and biological sensors, as well as promising technologies. Read more...
