| Eruption of Alaska's Okmok volcano linked to period of extreme cold in ancient Rome Posted: 22 Jun 2020 12:25 PM PDT Scientists and historians have found evidence connecting an unexplained period of extreme cold in ancient Rome with an unlikely source: a massive eruption of Alaska's Okmok volcano, located on the opposite side of the Earth. A new study uses an analysis of tephra (volcanic ash) found in Arctic ice cores to link this period of extreme climate in the Mediterranean with the caldera-forming eruption of Alaska's Okmok volcano in 43 BCE. |
| Experimentally identifying effective theories in many-body systems Posted: 22 Jun 2020 10:30 AM PDT One goal of science is to find physical descriptions of nature by studying how basic system components interact with one another. For complex many-body systems, effective theories are frequently used to this end. They allow describing the interactions without having to observe a system on the smallest of scales. Physicists have developed a new method that makes it possible to identify such theories experimentally with the aid of quantum simulators. |
| 300-million-year-old fish resembles a sturgeon but took a different evolutionary path Posted: 22 Jun 2020 10:30 AM PDT A re-examination of a 300-million-year-old fish, Tanyrhinichthys mcallisteri, revealed that its lifestyle more closely resembled that of the bottom-dwelling sturgeon, rather than the stealthy pike, as was previously believed. |
| Evidence supports 'hot start' scenario and early ocean formation on Pluto Posted: 22 Jun 2020 10:29 AM PDT A new study suggests that Pluto and other large Kuiper belt objects started out with liquid oceans which have been slowly freezing over time. |
| Synthetic materials mimic living creatures Posted: 22 Jun 2020 10:28 AM PDT Researchers have developed a family of soft materials that imitates living creatures. When hit with light, the film-thin materials come alive -- bending, rotating and even crawling on surfaces. |
| World's fastest Bose-Einstein condensate Posted: 22 Jun 2020 06:50 AM PDT Researchers have created a Bose-Einstein condensate with record speed, creating the fascinating phase of matter in about 100 femtoseconds. To get an idea of how quick that is, hundred femtoseconds compared to one second is proportionally the same as a day compared to the age of the universe. |
| Medicinal leech genome sequenced Posted: 18 Jun 2020 04:35 AM PDT A new study offers insights into the powerful anticoagulants contained in the saliva of leeches most often used in medical practice. |
