| Earth's magnetic poles not likely to flip anytime soon Posted: 07 Jun 2022 09:09 AM PDT The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal. However, a new study that pieces together evidence stretching back 9,000 years, suggests that the current changes aren't unique, and that a reversal may not be in the cards after all. |
| Detecting new particles around black holes with gravitational waves Posted: 07 Jun 2022 09:09 AM PDT Clouds of ultralight particles can form around rotating black holes. A team of physicists now show that these clouds would leave a characteristic imprint on the gravitational waves emitted by binary black holes. |
| Colossal collisions linked to solar system science Posted: 07 Jun 2022 09:09 AM PDT A new study shows a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun. |
| Bacterial cellulose could enable microbial life on Mars Posted: 06 Jun 2022 03:12 PM PDT An international research team has investigated the chances of survival of kombucha cultures under Mars-like conditions. Kombucha is known as a drink, sometimes called tea fungus or mushroom tea, which is produced by fermenting sugared tea using kombucha cultures -- a symbiotic culture of bacteria and yeast. Although the simulated Martian environment destroyed the microbial ecology of the kombucha cultures, surprisingly, a cellulose-producing bacterial species survived. |
| All wound up: A reversible molecular whirligig Posted: 06 Jun 2022 03:12 PM PDT Over the last few decades, researchers have built minuscule molecular machines that rotate or shuttle other molecules. However, it's difficult to determine the mechanical work and forces that these tiny contraptions produce, which is important when using them as nanorobots or in artificial muscles. Now researchers report molecular motors that twist and untwist like whirligig toys -- enabling the measurement of the energy and torque of their rotations. |
| Color-changing mouse model allows researchers to non-invasively study deep tissues Posted: 06 Jun 2022 11:54 AM PDT Biomedical and genetic engineers have developed a process to change the color of a mouse's tissue to better image its internal physiology. The approach will help researchers isolate and remove sources of strong background noise in biomedical images, giving them unprecedented access to observe, influence and image biological processes with a swiftly developing imaging technique called photoacoustic imaging. |
| The weird musical dynamics of a lava lake on Kilauea volcano Posted: 01 Jun 2022 11:28 AM PDT Before its big burst in 2018, Kilauea spent ten years erupting more gently. Research gives new insights into the volcano's longstanding lava lake, one feature of this eruption. |
| Turn up the beat! Groovy rhythm improves cognitive performance in groove enjoyers Posted: 27 May 2022 07:12 AM PDT Researchers found that music with a groove can enhance executive function and brain activity in relevant brain regions. However, this effect was only observed in individuals who reported that the music elicited a strong groove sensation and who felt more clear-headed after listening. These findings could lead to new strategies for enhancing cognitive function in normal and patient populations, such as accessible and effective exercise programs (enriched exercise). |
