New Biodegradable Plastics are Compostable in your Backyard

We use plastics in almost every aspect of our lives. These materials are cheap to make and incredibly stable. The problem comes when we’re done using something plastic—it can persist in the environment for years. Over time, plastic will break down into smaller fragments, called microplastics, that can pose significant environmental and health concerns.

The best-case solution would be to use bio-based plastics that biodegrade instead, but many of those bioplastics are not designed to degrade in backyard composting conditions...

First Bioavailable Compound that specifically Inhibits Free Radical Production in Mitochondria Prevents and Treats Metabolic Syndrome in mice

A potential therapeutic for one of the major chronic diseases of aging. Mopping up free radicals with antioxidants was the rage in the 1970’s; people were taking large, sometimes massive doses of various general antioxidants, including vitamins and minerals, to try to remove harmful byproducts of energy metabolism. The method was supposed to blunt the effects of aging and stave off chronic disease. The strategy didn’t work, and in some cases, it caused harm because untargeted antioxidants also compromised beneficial cellular signaling pathways. Over time, this area of research went on the shelf as mitochondrial theories of disease and aging fell into disfavor.

But research at the Buck offers a new way to deal with free radicals: rather than mop them up, take a pill that selectively...

New research finds Deep-Sleep Brain Waves Predict Blood Sugar Control

Researchers have uncovered a potential mechanism in humans that explains how and why deep-sleep brain waves at night are able to regulate the body’s sensitivity to insulin, which in turn improves blood sugar control the next day. (Illustration courtesy Matthew Walker)

Researchers have known that a lack of quality sleep can increase a person’s risk of diabetes. What has remained a mystery, however, is why.

Now, new findings from a team of sleep scientists at the University of California, Berkeley, are closer to an answer. The researchers have uncovered a potential mechanism in humans that explains how and why deep-sleep brain waves at night are able to regulate the body’s sensitivity to insulin, which in turn improves blood sugar control the next day.

Unveiling a groundbreaking and accurate AI-based method to classify cardiac function and disease using chest X-Rays. AI (artificial intelligence) may sound like a cold robotic system, but Osaka Metropolitan University scientists have shown that it can deliver heartwarming — or, more to the point, “heart-warning” — support. They unveiled an innovative use of AI that classifies cardiac functions and pinpoints valvular heart disease with unprecedented accuracy, demonstrating continued progress in merging the fields of medicine and technology to advance patient care. The results will be published in The Lancet Digital Health.

Valvular hea...
