New research led by University of Bristol scientists sheds light on how lepidosaurs — the most diverse clade of tetrapods, including lizards and snakes — have evolved remarkably varied jaw shapes, ...

Altermagnetism is a distinct form of magnetic order where the tiny constituent magnetic building blocks align antiparallel to their neighbors, but the structure hosting each one is rotated compared to ...

Nicknamed the Firefly Sparkle, the newly-discovered galaxy existed approximately 600 million years after the Big Bang and consisted of a least 10 star clusters. The most distant galaxies detected are ...

In a genomic study encompassing more than 300 genomes, researchers determined the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about ...

The Atacama Trench stretches along the eastern South Pacific Ocean, plunging to depths exceeding 8,000 m off the coast of northern Chile. The hadal zone, or the deepest 45% of the ocean (6,000-11,000 ...

Terastiodontosaurus marcelosanchezi lived in what is now Africa during the Eocene epoch, some 47 million years ago. The new species belongs to Trogonophidae, a small family of limbless, carnivorous, ...

Paleontologists have announced the discovery of a new species of quetzalcoatline azhdarchid pterosaur, Nipponopterus mifunensis, from the Late Cretaceous of Japan. Pterosaurs were highly successful ...

Fossil records show that dinosaurs evolved during the middle part of the Triassic period (247 to 237 million years ago). However, the domination of dinosaurs in terrestrial ecosystems was not seen ...

An accurate description of low-density nuclear matter is crucial for explaining the physics of neutron star crusts, according to a team of theoretical physicists led by Argonne National Laboratory’s ...

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered three ultra-massive galaxies — nearly as massive as our own Milky Way Galaxy — already in place within the first billion ...

When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first close glimpse of this ice-giant planet. Alongside the discovery of new moons and rings, baffling new mysteries ...

Dark comets are small bodies with no detected coma that have significant accelerations explainable by outgassing of volatiles, analogous to the first interstellar object 1I/2017 U1 ‘Oumuamua. These ...
