| Arctic rotifer lives after 24,000 years in a frozen state Posted: 07 Jun 2021 01:11 PM PDT Bdelloid rotifers are multicellular animals so small you need a microscope to see them. Despite their size, they're known for being tough, capable of surviving through drying, freezing, starvation, and low oxygen. Now, researchers have found that not only can they withstand being frozen, but they can also persist for at least 24,000 years in the Siberian permafrost and survive. |
| Antarctica: How have temperatures varied since the last glacial period? Posted: 07 Jun 2021 01:11 PM PDT Antarctica has experienced significant temperature changes, especially since the last glacial period. An international collaboration has now challenged previously accepted estimates of these variations, using new measurements. Their study highlights differences in behavior between East and West Antarctica, connected in particular to differing variations in their altitude. |
| Posted: 07 Jun 2021 01:10 PM PDT Ancient chickens lived significantly longer than their modern equivalents because they were seen as sacred -- not food -- archaeologists have found. |
| School lesson gone wrong leads to new, bigger megalodon size estimate Posted: 07 Jun 2021 01:10 PM PDT A more reliable way of estimating the size of megalodon shows the extinct shark may have been bigger than previously thought, measuring up to 65 feet, nearly the length of two school buses. |
| New insights into survival of ancient Western Desert peoples Posted: 07 Jun 2021 08:02 AM PDT Researchers have used more than two decades of satellite-derived environmental data to form hypotheses about the possible foraging habitats of pre-contact Aboriginal peoples living in Australia's Western Desert. |
| Soft tissue measurements critical to hominid reconstruction Posted: 04 Jun 2021 06:35 PM PDT Accurate soft tissue measurements are critical when making reconstructions of human ancestors, a new study has found. |
