Phys.org / How fishing may be changing one fish species at the molecular level
The pearly razorfish (Xyrichtys novacula) is a small marine animal that lives in sandy coastal waters and feeds on creatures like shrimp. Known locally in Spain's Balearic Islands as raors, it is a popular dish in many homes ...
Phys.org / SpaceX launches Starship on another test flight, this time with the most advanced Starlinks
SpaceX's mammoth Starship rocket blasted off Friday on another test flight stretching halfway around the world, this time releasing 20 of the most advanced Starlinks.
Phys.org / Orcas filmed ramming one of the world's heaviest fish so hard it explodes, possibly for fun
Orcas are known to be smart and ruthless hunters. They've been observed hunting a variety of prey, with some species, such as whales, larger than themselves. They use a wide range of strategies to hunt and kill prey, but ...
Phys.org / Why evolution never produced mammal teeth that slice and crush equally well
Evolution is all about trade-offs. Traits that may be beneficial in one situation may backfire in another. Over millions of years, species can become specialized for one way of living rather than being equally good at everything. ...
Medical Xpress / Aspirin reverses diet-driven depression-like behavior in mice
Depression is among the most common psychiatric disorders, estimated to affect between 280 million and 332 million people worldwide. This disorder is characterized by persistent sadness and hopelessness, low energy, a loss ...
Phys.org / Plumage reflectance framework offers new insight into how birds evolved heat-controlling feathers
Birds can inhabit various environments with different climates and temperatures, ranging from cold polar regions to scorching hot deserts. To survive and thrive in these very different environments, they need to effectively ...
Phys.org / Small tropical islands face dangerous humid heat by end of the century
Millions of people living on tropical islands could face a future of increasingly dangerous heat as climate change drives longer and more intense periods of humid conditions. While rising temperatures are often discussed ...
Tech Xplore / A spider-inspired robotic boat could track and rescue people in water
Rescue teams in coastal cities and towns often need to rescue people who are at risk of drowning. These operations often require emergency teams to locate and reach people in distress as quickly as possible, as even a short ...
Medical Xpress / New wearable ring tracks glucose, ketone and other biomarkers in sweat simultaneously
Engineers at the University of California San Diego created a smart ring that simultaneously and continuously monitors up to four different chemical biomarkers from finger sweat. The biomarkers the smart ring can monitor ...
Medical Xpress / Experimental plague vaccine strategy protects mice with missing key immune defenses
The plague has killed more people than World War II. The bacterium Yersinia pestis (Yp), which causes plague, has triggered three major pandemics throughout history, leaving behind a casualty toll of more than 200 million ...
Science X / Beneath pale ash, a quantum microscope reveals hidden traces of Neanderthal fire use preserved for millennia
An ancient hearth at El Salt (Spain) is giving up its secrets—not with flames, but with physics. Scientists have already established that Neanderthals used to make fires at this site (spanning from 80,000–45,000 years ago), ...
Medical Xpress / How the heart's 'little brain' helps it function and protects it against stress
For years, scientists have known that the heart has its own network of nerves, the intrinsic cardiac nervous system (ICNS), sometimes called its "little brain." Exactly how it functions has remained something of a mystery, ...
