Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related perception differences into account when designing white LED lighting that is more pleasing to the eye.
Read moreResearchers have developed an affordable, reliable paper-based sensor that works with a cellphone app to detect levels of iron in fortified food products.
Read moreSystems of tiny robots may someday build high-performance structures, from airplanes to space settlements.
Read moreAs global temperatures continue to rise, the thawing of permafrost is accelerated and mercury trapped in the frozen ground is now being released. The mercury is transforming into more mobile and potentially toxic forms that can lead to environmental and health concerns for wildlife, the fishing industry and people in the Arctic and beyond.
Read moreDrug addiction is a vicious cycle of reward and withdrawal. Chronic users often relapse because of the unpleasant physical and psychological symptoms they experience when they stop taking the drug. Now, researchers report metabolic changes in the brains of rats during methamphetamine self-administration and withdrawal that could help identify biomarkers and treatments for addiction.
Read more'Fake news' stories targeting corporations may be obnoxious, but a new study finds that they likely pose little threat to well-established brands.
Read moreComputational biologists have devised a software tool that can play a high-speed 'Match Game' to identify bioactive molecules and the microbial genes that produce them so they can be evaluated as possible antibiotics and other therapeutic agents.
Read moreScientists have developed an ultrasensitive new test to detect abnormal forms of the protein tau associated with uncommon types of neurodegenerative diseases called tauopathies. This advance gives them hope of using cerebrospinal fluid, or CSF — an accessible patient sample — to diagnose these and perhaps other, more common neurological diseases, such as Alzheimer's disease.
