Phys.org / JWST reveals most distant red galaxy yet at redshift 11.45
Using the James Webb Space Telescope (JWST), astronomers have discovered a new red galaxy at a redshift of approximately 11.45. The newfound galaxy, which received designation EGS-z11-R0, turns out to be the most distant ...
Phys.org / Unusual signal may prove existence of primordial black holes
It may well take years to prove, but a pair of University of Miami astrophysicists could be on the verge of a cosmic breakthrough that will confirm the existence of primordial black holes and the role they play in one of ...
Phys.org / Distant galaxy fades 20-fold in just two decades, challenging how supermassive black holes evolve
An international team led by a researcher at the Chiba Institute of Technology has discovered an extremely rare phenomenon: a galaxy about 10 billion light-years away whose brightness dropped to one-twentieth of its original ...
Phys.org / Uncovering the evolutionary limits of the COVID-19 virus
A new paper in Genome Biology and Evolution, indicates that while the COVID-19 virus has developed rapidly since 2019, it has done so within limited genetic channels. These genetic limits have remained unchanged. Despite ...
Phys.org / Massive insect body size 300 million years ago may not have been due to high atmospheric oxygen
Three-hundred-million years ago, Earth was very different. The continents had coalesced into Pangea, which was dominated in its equatorial regions by vast coal-swamp forests. With high atmospheric oxygen levels, wildfires ...
Phys.org / Extreme global climate outcomes are possible even at 2°C warming, study warns
Extreme climate impacts on people and the environment are often associated with very high levels of global warming (3 or 4°C). A new study led by the Helmholtz Centre for Environmental Research (UFZ) shows that this assumption ...
Phys.org / Tiny fossil eggs provide first physical evidence of Cretaceous bird-like dinosaurs in Korea
A major gap in South Korea's prehistoric record has been filled with the discovery of Onggwanoolithus aphaedoensis, the first known bird-type dinosaur eggs from the Cretaceous period of South Korea. The find, which is detailed ...
Phys.org / A captive chimp's instrumental performances hint at the evolution of vocal externalization
In February 2023, a resident at Kyoto University's Center for the Evolutionary Origins of Human Behavior—EHUB—treated researchers to a spontaneous musical performance. Ayumu, a 26-year-old male chimpanzee, removed floorboards ...
Phys.org / Ice Age animals and slice of Earth history found in central Texas water cave
A paleontologist from The University of Texas at Austin has discovered the fossilized remains of Ice Age animals that have never been found in Central Texas before—and he came across the bones while snorkeling for fossils ...
Phys.org / Radio signals at the edge of extreme stars come from far beyond their surfaces
Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams that sweep across the ...
Phys.org / Shell-cracking turtles defied mass extinction at the end of the Cretaceous period
The mass extinction at the boundary between the Cretaceous and Paleogene periods was catastrophic, wiping out much of life on Earth. Vertebrate groups that dominated at the time, such as dinosaurs and many large marine reptiles, ...
Phys.org / 'Cool' detectors cut neutrino mass upper limit by an order of magnitude
Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research groups has optimized its experiments to determine the mass of these "ghost particles." In doing ...
