Phys.org / Tiny galaxy, big find: Black hole discovered in nearby Segue 1
Small and unassuming, Segue 1 is a nearby dwarf galaxy containing only a handful of stars—too few to provide the gravity needed to keep itself from scattering into space. Like other dwarf galaxies, it was long believed ...
Phys.org / Why earthquakes sometimes still occur in tectonically silent regions
Earthquakes in the American state of Utah, the Soultz-sous-Forêts region of France or in the Dutch province of Groningen should not be able to occur even if the subsurface has been exploited for decades. This is because ...
Phys.org / Mathematical proof unites two puzzling phenomena in spin glass physics
A fundamental link between two counterintuitive phenomena in spin glasses—reentrance and temperature chaos—has been mathematically proven for the first time. By extending the Edwards–Anderson model to include correlated ...
Phys.org / Once tadpoles lose lungs, they never get them back
Tadpole species that lost their lungs through evolution never re-evolve them, even when environmental change would make it advantageous—bucking long-standing assumptions about how lost traits can reemerge, according to ...
Phys.org / Distributed quantum sensor network achieves ultra-high resolution near Heisenberg limit
Precise metrology forms a fundamental basis for advanced science and technology, including bioimaging, semiconductor defects diagnostics, and space telescope observations. However, the sensor technologies used in metrology ...
Phys.org / Topological insulator maintains quantum spin Hall effect at higher temperatures
Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function at very low temperatures, their practical application has been severely limited to date. Researchers ...
Phys.org / Chimpanzees in Uganda use flying insects to tend their wounds, study reveals
Animals respond to injury in many ways. So far, evidence for animals tending wounds with biologically active materials is rare. Yet, a recent study of an orangutan treating a wound with a medicinal plant provides a promising ...
Phys.org / High levels of short-chain PFAS found in blood of residents living near chemical facility
In a new study appearing in Environmental Science and Technology, researchers found high levels of ultrashort-chain per- and polyfluoroalkyl substances (PFAS) in blood samples taken from Wilmington, N.C. residents between ...
Phys.org / Australian researchers document a Murray cod swimming 860km in an unprecedented migration event
An Australian freshwater Murray cod has surprised scientists by swimming a marathon 860 kilometers (530 miles) along a major river system—believed to be a record for the species.
Phys.org / Nuclear clock technology enables unprecedented investigation of fine-structure constant stability
In 2024, TU Wien presented the world's first nuclear clock. Now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics.
Phys.org / How missing nutrients rewire fly brains to seek out beneficial microbes
New research from the Champalimaud Foundation (CF) reveals how missing just one essential amino acid can change gene expression and the brain's sensory systems, prompting animals to seek out protein-rich yeast and gut bacteria ...
Phys.org / Leaf arrangement steers vascular pattern evolution in ferns, research finds
Research by Assistant Professor Jacob S. Suissa at the University of Tennessee, Knoxville, is revealing complexity in how ferns have evolved. Instead of the vascular structure inside fern stems changing as a direct adaptation ...
