James Webb telescope discovers 'naked' black hole that somehow formed before its own galaxy - Live Science

Physicists at TU Dortmund University showed in January 2024 that a continuous time crystal could persist inside a semiconductor, with its oscillations remaining stable for hours. Now, in a new study published inNature Communications, Prof. Alex Greilich and his colleagues have found that multiple time crystals can emerge within the same material and synchronize their electron-nuclear spin oscillations. Time crystals are unusual physical systems whose internal behavior repeats in a regular rhythm over time, even though they are not being driven by a repeating external signal.

We’re introducing a new life sciences research group and laboratory at Anthropic. Our focus is on fundamental biology research using Claude: exploring datasets of DNA to identify uncharacterized protein families, generating hypotheses at scale, and testing them through experiments in the lab. This post introduces the team behind this work and shares early results in which Claude discovered a novel enzyme system with properties reminiscent of CRISPR, with only high-level direction from our scientists. Many discoveries that have revolutionized biology and medicine started with a scientist noticing something odd in the staggering diversity of molecular machines found in nature. Restriction enzymes, proteins that cut DNA at specific short sequences, were found in bacterial immune systems, where they destroy the DNA of invading viruses. Researchers realized they could use these enzymes to cut DNA at chosen places and splice genes from one organism into another, which launched the biotechnology industry. Taq polymerase, an enzyme that copies DNA at high temperatures, was identified in a bacterium in a Yellowstone hot spring.

Kent Hups said he couldn't contain his excitement when he came across several giant three-toed track prints that appeared to be T. Rex footprints in a North Dakota land formation last year. "I immediately started jumping up and down and hooting and hollering," Hups, a high school science teacher and research associate at the Denver Museum of Nature & Science, told ABC News. High school science teacher discovers rare T. Rex track: “A real pivotal moment.”Courtesy of Kent HupsHups discovered four footprints, each about 3 feet long, on a 23-foot trackway that researchers later determined originated from a T. Rex, according to the Denver Museum of Nature & Science. This is the first time scientists have ever discovered a T. Rex trackway, or a sequence of footprints, giving researchers insight into how the dinosaur moved through the landscape, according to the museum. Researchers estimate the tracks are about 66.5 million years old, according to the findings published in the Journal of Vertebrate Paleontology on Sept. 8. Researchers identified a T. Rex as the most likely trackmaker due to the footprints' exceptionally large size, the narrow toes and the abundance of T.

Earth has an unusually large moon compared with other rocky planets in the solar system, but scientists still do not fully understand how it formed. A new study from researchers at the Southwest Research Institute and the University of Arizona suggests that one long-overlooked factor may have played a major role in the Moon's birth: the physical strength of the worlds that collided. Using advanced computer simulations, the researchers examined the enormous impact thought to have occurred about 4.5 billion years ago between the young Earth and a Mars-sized object. Their results reveal strikingly different outcomes depending on the temperature and structural properties of the two bodies.
