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 / Electric field tunes vibrations to ease heat transfer
New research from the Department of Energy's Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about controlling heat flow in solid ...
Phys.org / Engineers improve infrared devices using century-old materials
After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control electrical currents—are few and far between. But with a pair of published papers, materials engineers ...
Tech Xplore / Humanoid robots master parkour and acquire human-like agility
Humanoid robots, robotic systems with a human-like body structure, have the potential of tackling various real-world tasks that are currently being completed by humans. In recent years, many robotics researchers and computer ...
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 ...
