| Comet makes a pit stop near Jupiter's asteroids Posted: 25 Feb 2021 11:37 AM PST After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population. |
| On the line: Watching nanoparticles get in shape Posted: 25 Feb 2021 05:25 AM PST Scientists have captured real-time, high-resolution videos of liquid structures taking shape as nanoparticles form a solid-like layer at the interface between oil and water. Their findings could help advance all-liquid robotics for targeted cancer drug delivery and other applications. |
| Scientists link star-shredding event to origins of universe's highest-energy particles Posted: 25 Feb 2021 05:25 AM PST A team of scientists has detected the presence of a high-energy neutrino in the wake of a star's destruction as it is consumed by a black hole. This discovery sheds new light on the origins of Ultrahigh Energy Cosmic Rays -- the highest energy particles in the Universe. |
| Ancient skeletal hand could reveal evolutionary secrets Posted: 25 Feb 2021 05:25 AM PST Evolutionary expert Charles Darwin and others recognized a close evolutionary relationship between humans, chimps and gorillas based on their shared anatomies, raising some big questions: how are humans related to other primates, and exactly how did early humans move around? |
| Asteroid dust found in crater closes case of dinosaur extinction Posted: 24 Feb 2021 11:35 AM PST Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater. |
| Twin atoms: A source for entangled particles Posted: 24 Feb 2021 11:34 AM PST One of the most important phenomena in quantum physics is entanglement - used for quantum krypography, quantum computers and many other applications. While it is easy to create pairs of entangled photons, it is much harder to create entangled atoms in a well-defined way. This has now been made possible using an experimental setup. |
| Cold gas pipelines feeding early, massive galaxies Posted: 24 Feb 2021 06:07 AM PST Researchers have detected cosmic pipelines supplying the cold gases necessary for the formation of massive galaxies and the creation of stars. It is the first direct observational evidence of the phenomenon in the early universe. |
| Treating rheumatoid arthritis with micromotors Posted: 24 Feb 2021 06:06 AM PST Rheumatoid arthritis is a chronic inflammatory disorder marked by joint pain, swelling and damage. Although medications, such as steroids, anti-inflammatory drugs and immunosuppressants, can help slow joint destruction and relieve pain, they have side effects and aren't completely successful. Now, researchers have developed magnesium-based micromotors propelled by hydrogen bubbles, which improved rheumatoid arthritis symptoms when injected into the joints of rats. |
