Medical Xpress / A banned chemical still lingers, and its strangest effect may depend on sex, genes and one common vitamin
In two new studies, researchers at the UC Davis MIND Institute have clarified how a long-banned group of chemicals, called polychlorinated biphenyls (PCBs), affect genetic activity. The research helps explain how biological ...
Phys.org / Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface ...
Medical Xpress / Molecular switch guides neurons through developing brain, revealing opposing migration pathways
During brain development, neurons can regulate their movement until they reach their final destination thanks to a "molecular switch" involving the protein Teneurin 4 (Ten4). This protein can guide neuronal migration through ...
Phys.org / Antarctica's ice shelves are vulnerable to melting from below—knowing how far ocean heat reaches is crucial
A rare dataset collected by instruments at the point where Antarctica's largest ice shelf begins to float reveals ocean processes that drive melting at this critical part of the continent.
Phys.org / Wreckage of a US Coast Guard ship lost during WWI has been found off the coast of England
The wreckage of a U.S. Coast Guard ship lost in a deadly attack more than a century ago, during World War I, was been discovered off the coast of England.
Phys.org / Single-molecule method rapidly screens custom enzymes from vast mutant libraries
Enzymes are proteins that catalyze chemical reactions in living organisms. They are widely applied in industries such as food production, detergents, pharmaceuticals, and chemicals. However, for commercial use, natural enzymes ...
Phys.org / Better volcano eruption predictions on Earth—and Venus—thanks to Mauna Loa study
When Mauna Loa erupted in 2022, the largest lava flow headed on a path headed directly toward Daniel K. Inouye State Highway 200, also known as Saddle Road, a critical route that carries many residents from their homes on ...
Phys.org / AI speeds chemists' search for better disinfectants
Chemists and computer scientists tapped AI to find new disinfectants to combat the growing threat of dangerous "superbugs." Their computational-experimental framework for developing quaternary ammonium compounds, or QACs, ...
Phys.org / Environmental DNA in NYC's East River reveals clues about nearby human and animal residents
Sequencing environmental DNA—or eDNA—from the East River in New York City can effectively monitor human diets and local wildlife, as well as the river's fish populations, report Mark Stoeckle and Jesse Ausubel of The Rockefeller ...
Phys.org / Investigating the disordered heart of glass
Recent research led by the University of Trento reveals that fundamental atomic vibrations remain unchanged also in ultra-stable glasses. This discovery advances the decade-long debate on the physics of disorder and opens ...
Medical Xpress / AI is not your therapist: The importance of seeking mental health care
Artificial intelligence (AI) is a strong tool that can help with different needs in an instant, but should AI replace or augment mental health specialists? A Baylor College of Medicine psychiatrist outlines how AI can be ...
Phys.org / Study reveals why food waste rises, falls as incomes grow
A new study by a Texas A&M AgriLife Research agricultural economist offers fresh insight into a global problem hiding in plain sight: How can we measure household food waste when it is so hard to track consistently?
