By tuning into a subset of brain waves, researchers have dramatically reduced the power requirements of neural interfaces while improving their accuracy — a discovery that could lead to long-lasting brain implants that can both treat neurological diseases and enable mind-controlled prosthetics and machines. The team, led by Cynthia Chestek, associate professor of biomedical engineering…

Nickel is one of the most abundant elements on earth. It is hard, yet malleable, magnetic at room temperature, and a relatively good conductor of electricity and heat. Most notably, nickel is highly corrosion resistant, which provides for a variety of uses by industry. However, scientists have recently discovered that nickel not only corrodes, but…

Researchers demonstrated that phosphorus-alloying significantly increases the activity of precious metal nanoparticles for the deoxygenation of sulfoxides into sulfides. In particular, ruthenium phosphide nanoparticles exhibit excellent catalytic activity and high durability against sulfur-poisoning, outperforming conventional catalysts. Transformation of sulfur-containing molecules is a fundamental and significant reaction in organic and pharmaceutical chemistry. However, the sulfur atom…

Researchers show models driving how respiratory droplets fell from a mannequin inside a water tunnel, which was inclined at different angles to mimic a person going up and down stairs. Using glass microspheres and lasers, they could visualize the flow motion behind the mannequins. Researchers describe the dispersion of cough-generated droplets that come from people…

Researchers have developed new antimicrobial technology for air filters which can in seconds kill bacteria, fungi and viruses including SARS-CoV-2 — providing a potential solution to prevent the spread of airborne infections. In a study, published today (9 March 2022) in journal Scientific Reports, the antimicrobial treatment for air filters — coated with a chemical…

Prediction models based on clinical characteristics and imaging findings may help reduce the false-positive rate in women with dense breasts who undergo supplemental breast cancer screening with MRI, according to a new study. Women with dense breast tissue have a much higher risk of breast cancer compared to those with average breast density. High breast…

Developing safe and sustainable fuels for nuclear energy is an integral part of an energy security mission. «Actinide nitride fuels are potentially a safer and more economical option in current power-generating systems,» said Bi Nguyen, Los Alamos National Laboratory Agnew postdoc and lead author of research recently published in the journal Inorganic Chemistry, which was…

A new study found that teen drivers and drivers 65 years and older — two age groups at a higher risk of being involved in an automobile accident — are more likely to be driving vehicles that are less safe, putting them at even higher risk of injury. The findings underscore the need for these…

Researchers report that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a »suicide gene» to pediatric brain tumor cells implanted in the brains of mice. The poly(beta-amino ester) nanoparticles, known as PBAEs, were part of a treatment that also used a drug to kill the cells and prolong the test animals’ survival.…

The selective oxidation of C—H bonds using oxygen has become a much simpler and more sustainable endeavor, thanks to a novel manganese (Mn)-based catalyst. Consisting of reusable Mg6MnO8 nanoparticles with unprecedented surface area, their catalyst enables the desired oxidative reactions to occur at mild temperature and pressure conditions without the need for toxic additives, opening…
