Researchers at EPFL bring diurnal and seasonal variations into the lab to test the performance of perovskite solar cells under realistic conditions. The findings are published in Nature Energy.
Scientists studying plant biochemistry at the US Department of Energy's Brookhaven National Laboratory recently made a surprising discovery: They found that a protein that turns on oil synthesis also activates a protein that puts the brakes on the same process. In a paper just published in the journal Plant Physiology, they describe how this seemingly paradoxical system keeps oil precursors perfectly balanced to meet plants' needs.
Results from a study of nearly 60,000 individuals suggest those at higher risk of developing Alzheimer's disease due to family history may demonstrate changes in memory performance as early as their 20s. Researchers from the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, and the University of Arizona gathered the data through an online word-pair memory test called MindCrowd, one of the world's largest scientific assessments of how healthy brains function.
A new type of treatment for osteoarthritis, currently in canine clinical trials, shows promise for eventual use in humans. The treatment, developed by Cornell University biomedical engineers, is a synthetic version of a naturally occurring joint lubricant that binds to the surface of cartilage in joints and acts as a cushion during high-impact activities, such as running.
About a million times a year, Americans with a torn meniscus in their knee undergo surgery in hopes of a repair. Certain tears can't be fixed or won't heal well, and many patients later suffer osteoarthritis. To improve meniscus healing, Duke scientists have developed a scaffold derived from a pig's meniscus, which performed better in lab tests than healing without a scaffold.
A team of researchers from Carnegie Mellon University has made a breakthrough in the field of noninvasive robotic device control. Using a noninvasive brain-computer interface (BCI), researchers have developed the first-ever successful mind-controlled robotic arm exhibiting the ability to continuously track and follow a computer cursor.
MIT researchers have devised a novel method to glean training information for machine-learning models, including those that can analyze medical images to help diagnose and treat brain conditions.
Surfaces that enable endothelial cell attachment without causing blood clotting are needed for various tissue engineering efforts. A new approach involving phage display has been used to identify unique peptides with these typically divergent characteristics.
A newly identified genus and species of worm-like, freshwater clam, commonly known as a shipworm, eats rock and expels sand as scat while it burrows like an ecosystem engineer in the Abatan River in the Philippines.
Artificial muscles made from polymers can now be powered by energy from glucose and oxygen, just like biological muscles. This advance may be a step on the way to implantable artificial muscles or autonomous microrobots powered by biomolecules in their surroundings. Researchers at Linköping University, Sweden, have presented their results in the journal Advanced Materials.
