Phys.org / How evolution shapes color diversity in coral reef fish

Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and patterns? A study conducted ...

Phys.org / Flipped chromosomal segments drive natural selection, Atlantic silversides study shows

When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits. But what about mobile aquatic species ...

Phys.org / Why woodpeckers rarely get rattled: Skulls built to control rotation, not cushion blows

Woodpeckers are well known for striking tree trunks with remarkable force and precision. These birds deliver thousands of high-speed impacts per day, generating mechanical loads that would destabilize the skulls of most other ...

Phys.org / New LVK catalog adds 128 gravitational-wave candidates, more than doubling detections

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. ...

Phys.org / Protecting wildlife from genetic collapse with newly identified 'early warning signals'

A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health unexpectedly collapses after appearing stable for long periods. By merging network theory with population ...

Phys.org / Neutrons reveal magnetic signatures of chiral phonons

Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures ...

Medical Xpress / Herpes simplex virus liquefies cell nuclei to build viral 'factories'

Herpes simplex virus partially liquefies the tightly packed, gel-like interior of human cell nuclei to copy itself faster, a new study shows. The research centers on how the nucleus of each human cell houses the genetic machinery ...

Phys.org / Elephants avoid humans far more than baboons, waterbucks or antelopes

Wild animal species respond very differently to human development, and as a result, they use ecological corridors in agricultural and urban areas in distinct ways. This emerges from research in Botswana by ecologist Marlee ...

Medical Xpress / Learning makes brain cells work together, not apart

When you get better at a skill—recognizing a familiar face in a crowd, spotting a typo at a glance, or anticipating the next move in a game—sensory neurons in your brain become more coordinated, sharing information rather ...
