Science X / Local 'Little Red Dots' stay eerily steady for up to 15 years, puzzling astronomers
Astronomers have spent over a decade tracking a unique type of compact dwarf galaxy, which continues to surprise everyone. Known as the "Little Red Dots" for their small, red appearance, these local galaxies look much like ...
Phys.org / Autonomous AI screening flags unreliable Lyme test results, boosting sensitivity to 95.7%
Computational point-of-care sensors can significantly improve access to diagnostics by enabling rapid patient testing outside centralized medical facilities. These tests rely on machine learning models to make diagnostic ...
Medical Xpress / Smartphone unlock can measure heart rate, potentially bringing health monitoring to billions worldwide
Wearable devices like smartwatches and fitness trackers have revolutionized the way we monitor our health. Worn around the clock, these devices quietly collect valuable data—from heart rate and blood oxygen levels to sleep ...
Phys.org / Mathematician solves origami donut efficiency challenge with fewest folds
Most people wouldn't think that it would take rigorous mathematical proof to show how many folds it takes to make a donut shape out of paper. Yet, no one could quite figure it out until recently.
Science X / Diet may tune learning and memory, from baby's first bite to Grandpa's dinner plate
For centuries, people have been trying to assess if what we eat can make us smarter. Ancient declarations and modern superfood trends have given rise to the belief that foods can enhance brainpower. But beyond the tales and ...
Phys.org / Single cell transforms into cannibalistic 'supergiant,' swallowing its clones whole
Researchers at Rensselaer Polytechnic Institute (RPI) have discovered a microscopic organism that can transform into a cannibalistic "supergiant" that drastically changes size, shape, and behavior, and abandons filter-feeding ...
Phys.org / Rare meteorite provides evidence of giant early planet
Four-and-a-half billion years ago, a massive world—possibly as big as the moon or even Mars—orbited our sun before crashing into another celestial body and shattering into rubble. Now, in a paper published in the journal ...
Phys.org / Light pulses uncover Higgs mode that reshapes perovskite crystal symmetry
Waves of light and sound interact to drive electronic and structural changes in a perovskite crystal. At the atomic scale, nothing is ever truly still. Materials that appear perfectly rigid and motionless to the naked eye ...
Medical Xpress / Antibody fragment prevents hemorrhages associated with new Alzheimer's treatments
In 2025, the European Medicines Agency approved two antibodies for Alzheimer's disease: lecanemab (LeqembiTM, from Biogen) and donanemab (Kisunla, from Eli Lilly and Co.), both based on immunotherapy (the use of molecules ...
Phys.org / One of our planets may be missing, and it could explain why the solar system looks the way it does
Our solar system has two ice giants, Uranus and Neptune, but there may have been a third. According to a new study published in the journal Icarus, this extra world might have triggered a violent planetary shuffling billions ...
Phys.org / Charred Bronze Age teeth unlock age at death despite cremation
Over 3,000 years ago, the people of Bronze Age Poland burned their dead and placed their ashes in urns, often destroying the intimate records of their lives preserved in their bones. Now, researchers have shown that some ...
Medical Xpress / New noninvasive tool may allow early detection of dangerous intestinal disease in preemies
A new noninvasive technology, called broadband optical spectroscopy (BOS), has promise for reliably detecting necrotizing enterocolitis (NEC) in premature infants at earlier stages, before this devastating intestinal disease ...
