| Using a multipronged approach to investigate the diet of ancient dogs Posted: 24 Feb 2021 09:03 AM PST A new study uses different techniques to improve the investigation of fossilized dog feces. |
| Evidence of dynamic seasonal activity on a Martian sand dune Posted: 24 Feb 2021 09:03 AM PST A scientist examined 11 Mars years of image data to understand the seasonal processes that create linear gullies on the slopes of the megadune in the Russell crater on Mars. |
| Reactivating aging stem cells in the brain Posted: 24 Feb 2021 08:30 AM PST As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers have now discovered a mechanism linked to stem cell aging - and how the production of neurons can be reactivated. |
| New fossil discovery illuminates the lives of the earliest primates Posted: 24 Feb 2021 07:08 AM PST A new fossil discovery is central to primate ancestry and adds to our understanding of how life on land recovered after the Cretaceous-Paleogene extinction event 66 million years ago that wiped out all dinosaurs, except for birds. |
| New study suggests supermassive black holes could form from dark matter Posted: 24 Feb 2021 07:08 AM PST A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving 'normal' matter, supermassive black holes could instead form directly from dark matter in high density regions in the centres of galaxies. The result has key implications for cosmology in the early Universe. |
| Posted: 24 Feb 2021 07:08 AM PST A research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of a scanning transmission X-ray microscope, they were able to film the recurring periodic magnetization structure in a crystal. |
| Evidence that Earth's first cells could have made specialized compartments Posted: 24 Feb 2021 06:06 AM PST New research provides evidence that the "protocells" that formed around 3.8 billion years ago, before bacteria and single-celled organisms, could have had specialized bubble-like compartments that formed spontaneously, encapsulated small molecules, and formed "daughter" protocells. |
| Fighting fit cockroaches have 'hidden strength' Posted: 23 Feb 2021 04:24 PM PST A new study has discovered that not all cockroaches are equal and 'super athletes' are more likely to win physical mating battles. The researchers scored aggressive interactions and carried out CT-scans. They found that dominant males have larger respiratory systems than submissive males of an identical size. The increased ability to deliver oxygen to their body tissue may enhance the fighting ability of these dominant males, and therefore play a crucial role in sexual selection. |
| Low-level jets create winds of change for turbines Posted: 23 Feb 2021 08:07 AM PST Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. Researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors. |
| 'Beautiful marriage' of quantum enemies Posted: 22 Feb 2021 01:41 PM PST Scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics. |
