Nickelate Superconductors are Intrinsically Magnetic

A muon, center, spins like a top within the atomic lattice of a thin film of superconducting nickelate. These elementary particles can sense the magnetic field created by the spins of electrons up to a billionth of a meter away. By embedding muons in four nickelate compounds at the Paul Scherrer Institute in Switzerland, researchers at SLAC and Stanford discovered that the nickelates they tested host magnetic excitations whether they’re in their superconducting states or not – another clue in the long quest to understand how unconventional superconductors can conduct electric current with no loss.

Waves of magnetic excitation sweep through this exciting new material whether it’s in superconducting mode or not — another possible...

A Fast-moving Star is Colliding with Interstellar Gas, creating a spectacular Bow Shock

Zeta Ophiuchi has had an interesting life. It began as a typical large star about twenty times more massive than the sun. It spent its days happily orbiting a large companion star until its companion exploded as a supernova about a million years ago. The explosion ejected Zeta Ophiuchi, so now it is speeding away through interstellar space. Of course, the supernova also expelled the outer layers of the companion star, so rather than empty space, our plucky star is speeding through the remnant gas as well. As they say on Facebook, it’s complicated. And that’s great news for astronomers, as a recent study shows.

Zeta Ophiuchi is most famous for be...

New link found that connects Cell Signaling Pathway to Development of Esophageal Cancers, Barrett’s Syndrome

Researchers believe pathway is a potential therapeutic target for gastroesophageal cancers. A team of researchers believe they have identified a cell signaling pathway responsible for the development of esophageal adenocarcinomas, an aggressive form of esophageal cancer that has gradually become more common, even in younger people.

Of the roughly 20,000 people in the U.S. diagnosed with esophageal cancer this year, just 4,000 are likely to still be alive in 2027. Such dire data has long driven researchers to try to understand the roots of the disease, but they have discovered little — until now.

“The incidence of esophageal cancers has increased several fold over the last few decades, making it the most common esophageal malignancy in the U.S...

New Bioremediation Material can Clean ‘Forever Chemicals’

A novel bioremediation technology for cleaning up per- and polyfluoroalkyl substances, or PFAS, chemical pollutants that threaten human health and ecosystem sustainability, has been developed by Texas A&M AgriLife researchers. The material has potential for commercial application for disposing of PFAS, also known as “forever chemicals.”

Published July 28 in Nature Communications, the research was a collaboration of Susie Dai, Ph.D., associate professor in the Texas A&M Department of Plant Pathology and Microbiology, and Joshua Yuan, Ph.D., chair and professor in Washington University in St...
