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 / 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 / First global map of mycorrhizal fungi reveals true scale of underground networks across the planet
Mycorrhizal fungi form underground networks that sustain plant life and help regulate Earth's climate by drawing carbon into soils. In a study published in Science, an international team of researchers produced the first ...
Phys.org / Rare deep-sea goblin sharks filmed in natural habitat for first time
The first published live observations of the rare goblin shark (Mitsukurina owstoni) in its natural deep-ocean habitat were reported in a new paper by a University of Hawai'i at Mānoa-led team of oceanographers. In the past, ...
Phys.org / 'Selection shadow' may explain why longer lives bring more age-related disease
A review article now published in Nature Reviews Genetics brings together evolutionary theory, comparative genomics and large-scale human genetics to explain why we age and why aging rates differ among individuals and species. ...
Phys.org / Wasp spider reveals rapid genetic adaptation during decades-long march into northern Europe
It has taken only a few decades: The wasp spider (Argiope bruennichi) has expanded its range from the Mediterranean region to northern Europe—even as far as southern Finland. In doing so, it has adapted genetically much faster ...
Phys.org / Massive Kamchatka earthquake has extended rupture that overlaps 1952 event, researchers find
Researchers combining two methods to reconstruct the rupture evolution of the July 2025 magnitude 8.8 Kamchatka earthquake found the rupture from the megathrust event extended about 500 kilometers (311 miles) from its epicenter.
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 DNA from Tuscan wells reveals origins of modern wine
Scientists analyzing 2,000-year-old grape seeds from ancient wells in Tuscany have mapped the most extensive genetic history of ancient grapevines recovered from a single site.
Phys.org / Organic molecule with ultranarrow emission spectrum could lead to better LEDs
Over the past several decades, light sources have gradually transitioned to light-emitting diodes, or LEDs, and inorganic LEDs are now used across a wide range of applications. In parallel, organic LEDs, or OLEDs, have become ...
Phys.org / First leather bag made from T-Rex cells fails to sell at Paris auction
A leather bag made from Tyrannosaurus rex cells failed to sell Thursday, the Paris auction house Drouot said, commenting that bids were well below expectations.
Phys.org / Light echoes reveal possible dark matter buildup around supermassive black holes
We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student ...
