Medical Xpress / It's right under your nose: Why some people can't find things in plain sight
Many households will recognize this familiar exchange. One person insists an object simply isn't there: impossible to find despite what they describe as a thorough and highly competent search. Another walks in, glances briefly ...
Phys.org / In Arizona's desert, tiny ants turn into living hygienists, climbing inside bigger ants' mandibles and cleaning them
Ants are known for many things. They fight, bite and sometimes compete for every crumb. We can now possibly add cleaning services to that list, according to a study published in the journal Ecology and Evolution.
Phys.org / Bonobos' peaceful reputation cracks after a rival group attack leaves an infant dead
Bonobos are often described as gentle apes, generally calm primates that are seen as peacemakers in the animal kingdom. But this reputation may be coming under attack as a new study published in Scientific Reports reveals ...
Phys.org / Museum drawer fossil reveals 200-million-year-old crocodile relative with a powerful bite
The fossil record has given us another new prehistoric species, named Eosphorosuchus lacrimosa (from the Greek personification of the morning star—the planet Venus), a member of the group called Crocodylomorpha, which includes ...
Medical Xpress / Cutting calories to slow aging—without compromising health
Restricting calorie intake in species such as mice, rhesus monkeys, and fruit flies has been shown to extend their lifespans. In some cases, these animals not only live longer, but are also free of disease. But when pushed ...
Phys.org / 'Ghost tunnels' guide sound waves in one direction while staying invisible to others
Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has engineered an acoustic metamaterial, ...
Medical Xpress / Overlooked ribosomal DNA may help explain human size differences
Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ribosomes—protein-building machines in our body. It helps build proteins by linking amino acids together, and can also ...
Phys.org / JWST spots methane on a giant exoplanet, but its star may be distorting the signal
Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new observations, published April 8 on the arXiv ...
Tech Xplore / Swiss biomethane shows potential for domestic energy self-sufficiency through biomass
By using biomass intelligently, Switzerland could meet a substantial percentage of its own gas needs. This is the conclusion reached by a study led by the Paul Scherrer Institute PSI. Gas imports could be significantly reduced ...
Phys.org / Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover
When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at HZDR have now observed ...
Medical Xpress / Teen cannabis use rose after California legalization, reversing years of decline
Teen cannabis use in Northern California increased following the legalization of adult recreational cannabis and later declined during the COVID-19 pandemic, according to new research from Kaiser Permanente published in JAMA ...
Phys.org / Sperm whale clicks follow similar rules to human speech
Sperm whales produce powerful clicks to communicate. To our ears, they sound nothing more than a series of repetitive, mechanical taps. But we could be a step closer to understanding some of their complex communication, as ...
