Phys.org / Ancient predator species discovered in South Africa challenges what we know about gorgonopsians
In a study published in The Anatomical Record, researchers have identified a new species of large-bodied gorgonopsian from the middle Permian. The discovery pushed back the known origins of when these apex predators began ...
Phys.org / A rare 'triple-double' radio galaxy discovered using MeerKAT
Astronomers have discovered an exceptionally rare radio galaxy that has three distinct pairs of radio lobes. This system falls into a subpopulation of radio galaxies known as "triple-double" radio galaxies (TDRGs). Located ...
Phys.org / Tropical volcanic eruptions trigger atmospheric changes that drive droughts in Asia
Volcanoes are both captivating and disastrous. Most are likely familiar with the common short-term dangers associated with them: explosive forces, lava, and even atmospheric particles disrupting air traffic. But researchers ...
Phys.org / High-rise living: How weaver ants build leaf nests using living 'zippers' and 'weights'
The rainforests of northern Australia are home to extraordinary ant colonies. Instead of dwelling in underground burrows, these ants inhabit canopies of trees, dozens of meters above the ground, inside hollow spheres they ...
Phys.org / Tracing the evolutionary history of chemical warfare between plants and insects
A new study published in Nature Ecology & Evolution connects plant and insect physiology, chemical ecology, molecular function, and evolutionary analysis to offer a new perspective on plant–insect coevolution. The research ...
Phys.org / Thawing permafrost becomes 25 to 100 times more permeable, experiments find
Experiments by University of Leeds researchers, published in Earth's Future, have shown that thawing of permafrost makes it between 25 and 100 times more permeable, allowing more climate change forcing gases to escape.
Phys.org / Scientists solve 40-year-old biological mystery behind sleeping sickness
To survive in the human bloodstream, the African trypanosome parasite wears a "cloak" made of proteins known as a variant surface glycoprotein (VSG). The study, published in Nature Microbiology, identifies the protein that ...
Phys.org / 100 million years ago, an 'evolutionary fuse' was lit in the deep ocean, sparking squid diversification
From color-changing skin to jet-propelled motion, squid and cuttlefish have long fascinated scientists. To understand the origins of their unique characteristics, many attempts have been made to define their evolutionary ...
Phys.org / Recovery from sudden permafrost collapse ranges from 10 years to a century, study suggests
Some Arctic regions regain their "greenness" within a decade of a sudden permafrost collapse, while others can take a century or more to recover, researchers report in a new study. The difference is directly related to each ...
Phys.org / How graphene oxide kills bacteria while sparing human cells
Hygiene in everyday items that touch the body—such as clothing, masks, and toothbrushes—is critically important. The underlying principle of how graphene selectively eliminates only bacteria has now been revealed. In Advanced ...
Phys.org / A universal scheme can verify any quantum state
Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these ...
Phys.org / TESS discovers an Earth-sized planet orbiting nearby M-dwarf star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation ...
