| Muddied waters: Sinking organics alter seafloor records Posted: 20 Jul 2021 03:58 PM PDT The remains of microscopic plankton blooms in near-shore ocean environments slowly sink to the seafloor, setting off processes that forever alter an important record of Earth's history, according to research from geoscientists. |
| New evidence of menopause in killer whales Posted: 20 Jul 2021 12:12 PM PDT Scientists have found new evidence of menopause in killer whales - raising fascinating questions about how and why it evolved. |
| 15,000-year-old viruses discovered in Tibetan glacier ice Posted: 20 Jul 2021 09:05 AM PDT Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date. |
| Rapidly diversifying birds in Southeast Asia offer new insights into evolution Posted: 20 Jul 2021 08:44 AM PDT New findings from zoologists working with birds in Southeast Asia are shining fresh light on the connections between animal behaviour, geology, and evolution - underlining that species can diversify surprisingly quickly under certain conditions. Sulawesi Babblers (Pellorneum celebense), shy birds that live in the undergrowth on Indonesian islands, have begun to diverge quite significantly despite being separated geographically for mere tens of thousands of years. |
