Science X / Baby-like reflexes that resurface in older adults may be warning of something much bigger
Ever seen a baby immediately grip something tightly as soon as it's placed in their palm? Or noticed their lips pucker or move when the area around the mouth is stimulated by tapping? These are the palmar and snout reflexes, ...
Phys.org / Collapsing stars could spawn mini-universes, offering new path to gravastars
Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses ...
Phys.org / AI fast-forwards molecular simulations by 10,000-fold
A new AI model has become so good at predicting how molecules evolve over time that, in the future, it could speed up the costly and time-consuming process of testing new drugs. In the long term, this technology could facilitate ...
Phys.org / A new kind of entanglement helps quantum sensors tune out noise
In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, making them more precise, more stable and more reliable. But eventually, physical constraints will ...
Medical Xpress / Gut microbes unlock hormone signaling that regulates gut movement, study suggests
Millions of people worldwide are periodically or chronically affected by gut-related conditions, such as irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD) and gastroenteritis. Uncovering the physiological ...
Phys.org / Genomes from Oceania offer new clues to human evolution
A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human populations in Oceania, filling a major gap in representation in genomics research. Despite harboring ...
Phys.org / Ancient clay figurine from Guatemala may bear the oldest written numbers in Mesoamerica
A clay figurine, small enough to cradle in your hand, with 11 dots arranged in columns where its head should be, may depict the oldest known example of written numbers in Mesoamerica.
Phys.org / Why cells started sticking together could help explain how animals first evolved
A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal evolution billions of years ago. These findings are the result of a collaboration among researchers at Indiana ...
Phys.org / Parents' heat warning songs may prime zebra finch chicks for heat before they hatch
Sealed within an eggshell, how can chicks prepare for the world into which they are about to hatch, with no obvious direct communication channel across the shell? Adult zebra finches produce distinctive high-pitched warning ...
Phys.org / Why restoring rivers isn't enough: New research shows fish are evolving in response to human-made rivers
This new international study is calling for a major rethink of how rivers are managed, arguing that fish are not just passive victims of environmental change but active participants in a feedback loop that can reshape entire ...
Phys.org / Extending cryo-electron microscopy beyond water
From paints and inks to catalysts and drug-delivery materials, many advanced technologies rely on substances dispersed in organic solvents. Yet directly observing these materials in their native liquid environments has remained ...
Phys.org / Electron matter waves gain ultrafast torque that flips handedness in femtoseconds
Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very small scales. In quantum mechanics, particles exhibit both particle-like and wave-like behaviors, ...
