Phys.org / Total solar eclipse quiets seismic noise for cities within its path
A seismic hush fell over U.S. and Canadian cities that were in the "path of totality" during the 8 April 2024 total solar eclipse, according to new research presented at the 2026 SSA Annual Meeting.
Medical Xpress / Melatonin appears to promote sleep by reducing visual sensitivity, zebrafish study suggests
Melatonin is a naturally produced molecule that has long been suspected to play a role in healthy sleep, but it has been unclear how it does so. Now, Caltech researchers have discovered a mechanism through which melatonin ...
Medical Xpress / Gut microbiome changes may signal Parkinson's disease risk
Analysis of microbes in the gut can reveal whether a person faces an elevated risk of Parkinson's disease, before they have developed any symptoms, suggests a new study led by University College London (UCL) researchers. ...
Phys.org / How maze-like magnetic patterns form and evolve in materials
The rapid increase in electric vehicle adoption in recent years has highlighted a crucial issue: the energy conversion efficiency of electric motors. In electric motors, iron loss or magnetic hysteresis loss is a primary ...
Medical Xpress / Bowel cancer immunotherapy clinical trial follow-up shows zero relapses
Patients with a specific type of bowel cancer who were treated with a short course of immunotherapy before surgery instead of post-op chemotherapy have remained cancer-free after almost three years of follow-up, according ...
Phys.org / Migratory blackcap bird brain mapped for the first time, opening a new era of 3D digital atlases
A migratory bird brain, the Eurasian blackcap (Sylvia atricapilla), has been mapped for the first time using high-resolution light microscopy. The open-source software tools developed, and the detailed processes published, ...
Phys.org / Why so many mollusks sound Greek—their naming evolves at a snail's pace
"A rose by any other name would smell as sweet," said Juliet Capulet in William Shakespeare's famous play. And the same is presumably true for mollusks, albeit with different odors. When you think about the scientific names ...
Phys.org / Surprising link between metallicity and superconductivity uncovered in twisted trilayer graphene
Superconductivity is a state of matter characterized by an electrical resistance of zero, typically at very low temperatures. Past studies have found that in various materials, this unique state is accompanied by unusual ...
Phys.org / The Colorado River disappeared from the geological record for 5 million years: Scientists now know where it went
Geologists have solved the mystery of the disappearance from the geological record, millions of years ago, of one of North America's most important waterways: the Colorado River. A paper published in Science shows that the ...
Phys.org / Universal quantum protocol extracts maximum work without knowing a system's state in advance
A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.
Medical Xpress / AI screening in brain organoids uncovers two drug candidates for Leigh syndrome
The need for medical treatments for rare diseases such as Leigh syndrome is high. However, low patient numbers make research into treatments difficult. Together with a team from the University of Luxembourg, researchers from ...
Phys.org / 'Tis the season: Sharing resources sustains ocean microbial biodiversity
Oceanographers from the University of Hawai'i at Mānoa discovered that microbial communities—from the sunlit surface to extreme depths—in the North Pacific Subtropical Gyre exhibit robust seasonal cycles. The study provides ...
