Every year, more than 5 million people in the U.S. are diagnosed with heart valve disease, but this condition has no effective long-term treatment. When a person’s heart valve is severely damaged by a birth defect, lifestyle, or aging, blood flow is disrupted. If left untreated, there can be fatal complications.

Valve replacement and repair are the only methods of managing severe valvular heart disease, but both often require repeated surgeries that are expensive, disruptive, and life-threatening. Most replacement valves are made of animal tissue and last up to 10 or 15 years before they must be replaced...

A Korean research team has succeeded in securing a basic technology for further improving the completeness level of neuromorphic devices. Their paper is published in the journal Nature Communications.

Researchers from the Korea Research Institute of Standards and Science observed the fine structure of the magnon, which is attracting attention as a key material for neuromorphic devices. As areas that are approximately 1,000 times finer than before were observed successfully, it is expected that the results will enable the design of more sophisticated neuromorphic devices.

Neuromorphic devices are next-...

Among the roughly 10 billion white dwarf stars in the Milky Way galaxy, a greater number than previously expected could provide a stellar environment hospitable to life-supporting exoplanets, according to astronomers at the University of California, Irvine.

In a paper published recently in The Astrophysical Journal, a research team led by Aomawa Shields, UC Irvine associate professor of physics and as...

Pomelo is a large citrus fruit commonly grown in Southeast and East Asia. It has a very thick peel, which is typically discarded, resulting in a considerable amount of food waste. In a new study published in ACS Applied Materials & Interfaces, University of Illinois Urbana-Champaign researchers explore ways to utilize waste pomelo-peel biomass to develop tools that can power small electric devices and monitor biomechanical motions.

“There are two main parts of the pomelo peel—a thin outer layer and a thick, white inner layer. The white part is soft and feels like a sponge when you push on it...
