The Age-Related Eye Disease Studies (AREDS and AREDS2) established that dietary supplements can slow progression of age-related macular degeneration (AMD), the most common cause of blindness in older Americans. In a new report, scientists analyzed 10 years of AREDS2 data. They show that the AREDS2 formula, which substituted antioxidants lutein and zeaxanthin for betacarotene, not only reduces risk of lung cancer due to beta-carotene, but is also more effective at reducing risk of AMD progression, compared to the original formula. A report on the study, funded by the National Institutes of Health, published in JAMA Ophthalmology.

“Because beta-carotene increased the risk of lung cancer for current smokers in two NIH-supported studies, our goal with AREDS2 was to create an equally ef...

Even though consumers won’t see it for years, researchers around the world are already laying the foundation for the next generation of wireless communications, 6G. An international team led by researchers at The University of Texas at Austin has developed components that will allow future devices to achieve increased speeds necessary for such a technological jump.

In a new paper published in Nature Electronics, the researchers demonstrated new radio frequency switches that are responsible for keeping devices connected by jumping between networks and frequencies while receiving data...

In a paper recently published in The Planetary Science Journal, NASA scientists and engineers give new details about the agency’s Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031. DAVINCI is the first mission to study Venus using both spacecraft flybys and a descent probe.

DAVINCI, a flying analytical chemistry laboratory, will measure critical aspects of Venus’s massive atmosphere-climate system for the first time, many of which have been measurement goals for Venus since the early 1980s...

Researchers have identified an alternative to lithium-based battery technology by developing sodium glassy electrodes capable of supporting long-duration, grid-scale energy storage. Lithium-ion batteries are currently the preferred technology to power electric vehicles, but they’re too expensive for long-duration grid-scale energy storage systems, and lithium itself is becoming more challenging to access.

While lithium does have many advantages — high energy density and capacity to be combined with renewable energy sources to support grid-level energy storage — lithium carbonate prices are at an all-time high...
