| Hidden in genetics: The evolutionary relationships of two groups of ancient invertebrates revealed Posted: 01 Jul 2022 01:33 PM PDT Using high quality molecular data, researchers have re-investigated a long-standing question about the position of two phyla of small aquatic invertebrates -- Kamptozoa and Bryozoa -- on the evolutionary tree. |
| How placentas evolved in mammals Posted: 01 Jul 2022 01:32 PM PDT The fossil record tells us about ancient life through the preserved remains of body parts like bones, teeth and turtle shells. But how to study the history of soft tissues and organs, which can decay quickly, leaving little evidence behind? In a new study, scientists use gene expression patterns, called transcriptomics, to investigate the ancient origins of one organ: the placenta, which is vital to pregnancy. |
| Dinosaurs took over amid ice, not warmth, says a new study of ancient mass extinction Posted: 01 Jul 2022 11:31 AM PDT There is new evidence that ancient high latitudes, to which early dinosaurs were largely relegated, regularly froze over, and that the creatures adapted -- an apparent key to their later dominance. |
| Posted: 30 Jun 2022 08:44 AM PDT The eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed. |
| The art of getting DNA out of decades-old pickled snakes Posted: 30 Jun 2022 05:33 AM PDT Using pickled snakes collected decades ago and stored in an underground bunker of collections, scientists have found ways to get DNA samples from specimens previously considered near-impossible to get genetic data from. They used that DNA to solve a long-standing mystery about which family an elusive snake from the island of Borneo belongs to. |
| Shrimps and worms among first animals to recover after largest mass extinction Posted: 29 Jun 2022 12:01 PM PDT Researchers studying ancient sea bed burrows and trails have discovered that bottom burrowing animals were among the first to bounce back after the end-Permian mass extinction. |
| Life in Earth's interior as productive as in some ocean waters Posted: 29 Jun 2022 09:11 AM PDT Microorganisms in aquifers deep below the earth's surface produce similar amounts of biomass as those in some marine waters. Applying a unique, ultra-sensitive measurement method using radioactive carbon, they were able to demonstrate for the first time that these biotic communities in absolute darkness do not depend on sunlight. Instead, they can obtain energy autonomously from rock oxidation or from compounds transported into the deep. |
| New kangaroo described -- from Papua New Guinea Posted: 29 Jun 2022 05:40 AM PDT Australian palaeontologists have described a new genus of giant fossil kangaroo from the mountains of central Papua New Guinea. The new description of the fossil kangaroo has found that, rather than being closely related to Australian kangaroos, it most likely belongs to a unique genus of more primitive kangaroo found only in PNG. |
