Rare fossil teeth overturn long-held views about evolution of vertebrates
An international team of researchers has discovered 439-million-year-old remains of a toothed fish that suggest the ancestors of modern osteichthyans (ray- and lobe-finned fish) and chondrichthyans (sharks and rays) originated much earlier than previ.....»»
Researchers reveal water-assisted oxidative redispersion of metal nanoparticles
Oxidative redispersion at elevated temperatures has long been utilized in heterogeneous catalysis for the regeneration of sintered metal catalysts and the synthesis of metal single atom and cluster catalysts. These redispersion processes require a co.....»»
Evidence suggests saber-toothed cats held onto their baby teeth to stabilize their sabers
California's state fossil—are familiar to anyone who has ever visited Los Angeles' La Brea Tar Pits, a sticky trap from which more than 2,000 saber-toothed cat skulls have been excavated over more than a century......»»
Behavioral therapy against aging: Researchers study the effect of therapies on older dogs
It is well known that getting plenty of exercise and mental training are important for a long and healthy life. But which is more effective? Do the tasks develop abilities that go beyond them?.....»»
Long snouts protect foxes when they dive headfirst into snow, study finds
When hunting for mice in winter, red and Arctic fox are known to plunge headfirst at speeds of 2–4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new Cornell University study......»»
Fragility crossover mediated by covalent-like electronic interactions in metallic liquids
In the field of glass and liquid sciences, the so-called fragility is a key concept that characterizes how rapidly the liquid dynamics showdown on lowering the temperature. However, a long-standing challenge is that the occurrence of crystallization.....»»
Study says California"s 2023 snowy rescue from megadrought was a freak event. Don"t get used to it
Last year's snow deluge in California, which quickly erased a two decade long megadrought, was essentially a once-in-a-lifetime rescue from above, a new study found......»»

Aggressive wall lizard provides clues to understanding evolution
Body shape, color and behavior often evolve together as species adapt to their environment. Researchers from Lund University in Sweden have studied this phenomenon in a specific type of large, bright green and aggressive common wall lizard found near.....»»
Microgravity-grown crystals reveal new insights into protein structures
Biochemists have long been working around a blind spot when it comes to proteins. They know that hydrogen constitutes nearly half of the atoms in proteins, but how they contribute to protein function in these complex structures has been less clear. H.....»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Research shows baby bird development harmed by sound of cars
A new study by Deakin researchers, published in Science, proves that traffic noise exposure in baby birds directly interferes with their development, which causes severe and long-lasting harm to those chicks......»»
Isotopic evidence reveals surprising dietary practices of ancient hunter-gatherers
It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the diet.....»»
New study reveals mystery of decaying exoplanet orbits
A new study led by researchers at Durham University has uncovered a novel mechanism that could solve a long-standing mystery about decaying planetary orbits around stars like our sun......»»
Here"s why we should put a gravitational wave observatory on the moon
Scientists detected the first long-predicted gravitational wave in 2015, and since then, researchers have been hungering for better detectors. But the Earth is warm and seismically noisy, and that will always limit the effectiveness of Earth-based de.....»»
