Researchers have discovered that a single treatment to inhibit a gene called PTB in mice converts native astrocytes, brain support cells, into neurons that produce the neurotransmitter dopamine. As a result, the mice’s Parkinson’s disease symptoms disappear.

Xiang-Dong Fu, PhD, has never been more excited about something in his entire career. He has long studied the basic biology of RNA, a genetic cousin of DNA, and the proteins that bind it. But a single discovery has launched Fu into a completely new field: neuroscience.

For decades, Fu and his team at University of California San Diego School of Medicine studied a pr...

In the ongoing process of miniaturization of logic and memory devices in electronic circuits, reducing the dimensions of interconnects—metal wires that link different components on a chip—is crucial to guarantee fast response of the device and improve its performance...

The young star HBC 672 is known by its nickname of Bat Shadow because of its wing-like shadow feature. The NASA/ESA Hubble Space Telescope has now observed a curious “flapping” motion in the shadow of the star’s disc for the first time. The star resides in a stellar nursery called the Serpens Nebula, about 1300 light-years away.

The Hubble Space Telescope captured a striking observation of the fledgling star’s unseen, planet-forming disc in 2018...

A new study led by researchers at the USC Leonard Davis School of Gerontology is the first to demonstrate that a tiny protein has a big impact on health and longevity in both animals and humans.

The researchers examined humanin, a peptide encoded in the small genome of mitochondria — the powerhouses of the cell. From experiments in laboratory animals to measurements in human patients, the multi-site collaboration demonstrates how higher levels of humanin in the body are connected to longer lifespans and better health. It is linked to a lower risk for diseases such as Alzheimer’s.

“Humanin has long been known to...
