Biomedical engineer explores new use for synthetic platelets: Treating inherited bleeding disorders
Biomedical engineers report a new application for their synthetic platelets: treating the genetic condition that prevents blood from clotting, Von Willebrand disease (VWD). The most common of all bleeding disorders, VWD is found in up to 1% of the U.S….
Physicists find unusual waves in nickel-based magnet
Perturbing electron spins in a magnet usually results in excitations called ‘spin waves’ that ripple through the magnet like waves moving across the surface of a pond that’s been struck by a pebble. Physicists have now discovered dramatically different…
Research shows why some children may be slower to learn words
A new study investigates where toddlers look when they learn new words. It finds that children with larger vocabularies looked quickly towards objects when learning new words. Meanwhile, children who knew fewer words looked back and forth between objec…
Even as temperatures rise, this hydrogel material keeps absorbing moisture
Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.
The wound dressing that can reveal infection
A nanocellulose wound dressing that can reveal early signs of infection without interfering with the healing process has been developed.
Using machine learning to find reliable and low-cost solar cells
Hybrid perovskites are organic-inorganic molecules that have received a lot of attention over the past 10 years for their potential use in renewable energy. Some are comparable in efficiency to silicon for making solar cells, but they are cheaper to ma…
Tiny biobattery with 100-year shelf life runs on bacteria
A tiny biobattery that could still work after 100 years has been developed.
Next decade decisive for PV growth on the path to 2050
Global experts on solar power strongly urge a commitment to the continued growth of photovoltaic (PV) manufacturing and deployment to power the planet, arguing that lowballing projections for PV growth while waiting for a consensus on other energy path…
Chemists propose ultrathin material for doubling solar cell efficiency
Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfid…
Warning labels on restaurant menus reduced likelihood consumers would order high-sugar foods
Added-sugar warning labels reduced the likelihood that consumers would order items containing high amounts of added sugar in an online experiment.
