Researchers in Japan have synthesised nanoporous ultra-high-entropy alloys that contain 14 elements. Tests showed the alloys were capable of splitting water and performed better than commercial platinum-based hydrogen evolution reaction catalysts and iridium-based oxygen evolution reaction catalysts. ‘Most conventional alloy catalysts contain a primary metal constituent with high atomic percentage, …

During nightly foraging trips, closely bonded females of common vampire bats (Desmodus rotundus) depart their roost separately, but often reunite far outside the roost to hunt together, says a new paper published today in the journal PLoS Biology.

The tail of bipedal non-avian dinosaurs played a role analogous to the swinging arms of humans during walking and running, according to new research led by Harvard University’s Dr. Peter Bishop. Computer simulations of running locomotion in a modern tinamou bird (brown) and the extinct theropod dinosaur Coelophysis (green). Gray …

An international team of researchers led by the University of Georgia has documented ultraviolet biofluorescence in live southeastern pocket gophers (Geomys pinetis) and in museum specimens of four additional gopher species. Southeastern pocket gophers (Geomys pinetis) are biofluorescent, giving off a colored glow when illuminated with UV light. Image credit: …

Pull out your red-and-blue 3D glasses: Ingenuity’s latest, ground-hugging flight has delivered an anaglyph 3D tableau of the Martian landscape. Its mission was to take color images of a specific geological target: a 30-foot hunk of craggy orange rock that the Perseverance team has nicknamed “Faillefeu,” after a medieval abbey …

Researchers have sequenced analyzed the genome of the Atlantic puffin (Fratercula arctica), a small auk with a large head and a colorful bill. Using the genome-wide resequencing data, they’ve also identified four main puffin population clusters consisting of (i) Spitsbergen (High Arctic), (ii) Canada, (iii) Isle of May, and (iv) …

Paleontologists have unearthed and described the fragmentary fossilized remains of a non-pterodactyloid pterosaur in the Atacama Desert in northern Chile.

The newly-described pterosaur inhabited the ancient supercontinent of Gondwana some 160 million years ago …

A new study in mice shows that normally, the immune system keeps potentially pathogenic fungi such as Candida albicans in check, targeting them when they switch into a state that can cause harm; when the system is off-balance, disease is more likely to occur.

Paleontologists have uncovered seven well-preserved teeth from the extinct shark genus Petalodus in Shanxi province, China. Life restoration of Petalodus sharks. Image credit: Dinghua Yang. Petalodus is a small genus of Petalodontiformes, a intriguing group of extinct marine cartilaginous fish that flourished from the Carboniferous to the Permian period. First …

A new genus and species of palaeoscolecid worm has been identified from two specimens found in the Burgess Shale-type deposits in Utah, the United States. Arrakiscolex aasei.
