Phys.org / Snakes' biting styles revealed in fine detail for the first time
Few actions in nature inspire more fear and fascination than snake bites. And the venomous reptiles have to move fast to sink their fangs into their prey before their victim flinches, which may be as little as 60 ms when ...
Phys.org / Coastal gray wolves display unexpected hunting behavior with unknown ecosystem impact
On Prince of Wales Island, Alaska, gray wolves are doing something unexpected: hunting sea otters. This surprising dietary shift appears to have notable implications for both ecosystems and wolf health, but little is known ...
Phys.org / Stone tools trace Paleolithic Pacific migration into North America
A new analysis of stone tools offers strong evidence for the theory that ancient people from the Pacific Rim traveled a coastal route from East Asia during the last ice age to become North America's First Peoples, according ...
Phys.org / Astronomers expose CO-dark molecular gas, previously invisible to telescopes
An international team of astronomers has created the first-ever large-scale maps of a mysterious form of matter, known as CO-dark molecular gas, in one of our Milky Way's most active star-forming neighborhoods, Cygnus X. ...
Phys.org / Chemists create publicly available tool that provides unrivaled look at RNA inside cells
The interior of a cell is packed with proteins and nucleic acids, such as RNA, all of which need to perform specific functions at the exact right time. If they don't, serious diseases—ALS, Huntington's or many cancers—can ...
Phys.org / Forests recovering from acid rain mine rocks for nutrients, long-term study reveals
In the White Mountains of New Hampshire, the streams are telling us a story about forest recovery following acid rain and logging. According to a new study in the Proceedings of the National Academy of Sciences, long-term ...
Phys.org / Dinosaurs in New Mexico thrived until the very end, study shows
For decades, many scientists believed dinosaurs were already dwindling in number and variety long before an asteroid strike sealed their fate 66 million years ago.
Phys.org / Dinosaur 'mummies' unlock secrets of their real-life appearance
In a new paper in Science, experts from the University of Chicago describe steps that took place some 66 million years ago to transform the carcasses of a duck-billed dinosaur, Edmontosaurus annectens, into dinosaur "mummies" ...
Phys.org / The island split in two by time: How ancient rifting reshaped Madagascar's landscape
Madagascar's landscape tells a story of deep time: ancient rifting and geological tilting sculpted the island's dramatic topography and steered its rivers, setting the stage for the evolution of its extraordinary biodiversity.
Phys.org / Scientists create a new form of light matter in a quasicrystal
Researchers have for the first time created a reconfigurable polariton 2D quasicrystal. The team from the Skolkovo Institute of Science and Technology (Skoltech), in collaboration with colleagues from the University of Iceland, ...
Phys.org / Microscopic 'ocean' on a chip reveals new nonlinear wave behavior
University of Queensland researchers have created a microscopic "ocean" on a silicon chip to miniaturize the study of wave dynamics. The device, made at UQ's School of Mathematics and Physics, uses a layer of superfluid helium ...
Phys.org / South American long-necked dinosaur could easily stand on two legs, computational study finds
Sixty-six million years ago, two genera of long-necked, quadrupedal dinosaurs had an advantage over other sauropods: they could easily stand on their hind legs for extended periods. This allowed them to scare off potential ...
