Medical Xpress / Brain circuit that times a state of low metabolism could have implications for space travel
You have gone without food for days, and the temperature drops to near freezing. What do you do? For some animals, the answer is influenced by the brain's circadian clock. Hummingbirds, bats, and mice are among the animals ...
Phys.org / Student astronomer discovers 'Rosetta Stone' for mysterious cosmic signals
An international team led by astronomers at the University of Sydney has uncovered the clearest evidence yet for the origin of an unusual class of cosmic signals. In doing so, they have identified a rare stellar system that ...
Phys.org / Endangered basking sharks rely on the ocean twilight zone during long-distance migrations
Endangered basking sharks aren't fasting during long-distance migrations. A new study led by the Woods Hole Oceanographic Institution shows that they may be foraging along the way, and in much deeper areas of the ocean than ...
Phys.org / 'Out-of-place' rocks reveal how a young ocean formed
Deep below the Tyrrhenian Sea offshore Italy, scientists drilled into what they thought would be dark mantle rock—and found pieces of granite that seemingly had no business being there. Those unexpected intrusions turned ...
Phys.org / New gold-palladium catalysis mechanism could advance bio-based chemical manufacturing
The building‐block chemicals behind everyday products—like shampoo bottles, food containers, and kitchen spatulas—are largely derived from oil. Researchers are now working to replace those fossil‐fuel‐based inputs with materials ...
Medical Xpress / Copper imbalance tied to autism's social symptoms and white matter development
Trace elements are needed only in small amounts, but they can have large effects on the developing brain. A research team led by Niigata University has now reported that copper, an essential trace element, may help connect ...
Phys.org / White storks: Why introducing non‑native species in rewilding projects can be a good idea
White storks (Ciconia ciconia) are a majestic bird with a two-meter wingspan and an enormous circular nest.
Phys.org / Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate ...
Medical Xpress / Basil and fennel compound may build up dangerous DNA damage in vulnerable people
Methyleugenol is a component of essential oils and is found in basil, tarragon, nutmeg, and fennel. When ingested through food, it can be converted in the liver into a reactive form that induces chemical alterations in DNA. ...
Phys.org / How Jupiter may have redirected life's ingredients toward Earth 4.5 billion years ago
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution ...
Phys.org / Invasive caiman may pose new challenges for Everglades restoration
In the canals, wetlands and marshes of the Florida Everglades, the spectacled caiman has quietly expanded its foothold, threatening an already-vulnerable ecosystem. A new University of Florida study published in Frontiers ...
Phys.org / Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan
Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory ...
