| Amazon indigenous group's lifestyle may hold a key to slowing down aging Posted: 26 May 2021 03:58 PM PDT The Tsimane indigenous people of the Bolivian Amazon experience less brain atrophy than their American and European peers. The decrease in their brain volumes with age is 70% slower than in Western populations. |
| Widespread coral-algae symbioses endured historical climate changes Posted: 26 May 2021 03:58 PM PDT One of the most important and widespread reef-building corals, known as cauliflower coral, exhibits strong partnerships with certain species of symbiotic algae, and these relationships have persisted through periods of intense climate fluctuations over the last 1.5 million years, according to a new study. |
| Technology to monitor mental wellbeing might be right at your fingertips Posted: 26 May 2021 03:58 PM PDT To help patients manage their mental wellness between appointments, researchers have developed a smart device-based electronic platform that can continuously monitor the state of hyperarousal, one of the signs of psychiatric distress. They said this advanced technology could read facial cues, analyze voice patterns and integrate readings from built-in vital signs sensors on smartwatches to determine if a patient is under stress. |
| Unveiling what governs crystal growth Posted: 26 May 2021 03:58 PM PDT Crystals are wonders of nature and science with important applications in electronics and optics. Scientists have new insights into how gallium nitride crystals grow.

| Study finds ongoing evolution in Tasmanian Devils' response to transmissible cancer Posted: 26 May 2021 12:00 PM PDT Researchers studied the evolution of Tasmanian devils in response to a unique transmissible cancer. The team found that historic and ongoing evolution are widespread across the devils' genome, but there is little overlap of genes between those two timescales. These findings suggest that if transmissible cancers occurred historically in devils, they imposed natural selection on different sets of genes. |

| Stormwater could be a large source of microplastics and rubber fragments to waterways Posted: 26 May 2021 10:21 AM PDT In cities, heavy rains wash away the gunk collecting on sidewalks and roads, picking up all kinds of debris. However, the amount of microplastic pollution swept away by this runoff is currently unknown. Now, researchers report that stormwater can be a large source of microplastics and rubber fragments to water bodies and, with a proof-of-concept experiment, show that a rain garden could keep these microscopic pieces out of a storm drain. |
| Geological riddle solved: Roof of the World has gotten higher Posted: 26 May 2021 10:21 AM PDT There has long been controversy about whether the world's highest region, Tibet, has grown taller during the recent geological past. New results indicate that the 'Roof of the World' appears to have risen by up to 600 meters and the answer was found in underwater lava. The knowledge sheds new light on Earth's evolution. |

| Brain tumors caused by normal neuron activity in mice predisposed to such tumors Posted: 26 May 2021 10:21 AM PDT Researchers have found that normal exposure to light can drive the formation and growth of optic nerve tumors in mice -- and maybe people -- with a genetic predisposition. Such tumors can lead to vision loss. |
| Electric fish -- and humans -- pause before communicating key points Posted: 26 May 2021 10:21 AM PDT Electric fish pause before sharing something particularly meaningful. Pauses also prime the sensory systems to receive new and important information. The study reveals an underlying mechanism for how pauses allow neurons in the midbrain to recover from stimulation. |
| Embryos of many species use sound to prepare for the outside world Posted: 26 May 2021 10:21 AM PDT It's well known that reptiles depend on temperature cues while in the egg to determine a hatchling's sex. Now, researchers say that embryos of many different animal species also rely on acoustic signals in important ways. They call this phenomenon 'acoustic developmental programming.' |
| Posted: 26 May 2021 10:21 AM PDT Researchers have used 'swarm learning' - a novel, artificial intelligence technology - to detect blood cancer, lung diseases and COVID-19 in data stored in a decentralized fashion. |
| Slender robotic finger senses buried items Posted: 26 May 2021 10:21 AM PDT Researchers developed a 'Digger Finger' robot that digs through granular material, like sand and gravel, and senses the shapes of buried objects. The technology could aid in disarming buried bombs or inspecting underground cables. |
| How the mold influences a chocolate bar's crystalline structure Posted: 26 May 2021 10:21 AM PDT When enjoying a chocolate bar, most people don't think about how the molecules within it are organized. But different arrangements of the fats in chocolate can influence its taste and texture. Now, researchers have found that the side of a chocolate bar facing the mold has a more orderly crystalline structure than the side facing air, knowledge that might help chocolatiers produce tastier confections, the researchers say. |

Fernández-Ontiveros, of the Istituto Nazionale di Astrofisica (INAF) in Rome and Teo Muñoz-Darias, of the Instituto de Astrofísica de Canarias (IAC), have written an article in which they describe the different states of activity of a large sample of supermassive black holes in the centres of galaxies. |
| Non-parents expand 'facial dexterity' in caring for infants among primates Posted: 26 May 2021 08:55 AM PDT Non-parents expand the range of their facial expressions in caring for infants among primates. The study shows the ability, among non-relatives, to both decipher facial expressions and to be attuned to others' emotional states, revealing the evolutionary nature of communication. |
| Warm ice may fracture differently than cold ice Posted: 26 May 2021 08:55 AM PDT Researchers have found strong evidence that warm ice - that is, ice very close in temperature to zero degrees Celsius - may fracture differently than the kinds of ice typically studied in laboratories or nature. A new study takes a closer look at the phenomenon. |
| What causes the deep Earth's most mysterious earthquakes? Posted: 26 May 2021 08:55 AM PDT The cause of Earth's deepest earthquakes has been a mystery to science for more than a century, but a team of scientists may have now cracked the case. New research provides evidence that fluids play a key role in deep-focus earthquakes -- which occur between 300 and 700 kilometers below the planet's surface. |

| Memory details fade over time, with only the main gist preserved Posted: 26 May 2021 05:50 AM PDT What information is retained in a memory over time, and which parts get lost? These questions have led to many scientific theories over the years, and now a team of researchers have been able to provide some answers. |
| Resetting the biological clock by flipping a switch Posted: 26 May 2021 05:50 AM PDT The biological clock is present in almost all cells of an organism. As more and more evidence emerges that clocks in certain organs could be out of sync, there is a need to investigate and reset these clocks locally. Scientists from the introduced a light-controlled on/off switch to a kinase inhibitor, which affects clock function. This gives them control of the biological clock in cultured cells and explanted tissue. |
| Why a vacation seems like it will end as soon as it begins Posted: 26 May 2021 05:50 AM PDT Time not only flies when you're having fun - sometimes anticipating a fun event makes it feel like it will be over as soon as it begins, a new study suggests. Researchers found that people judge future positive events as being both farther away as well as shorter in duration than negative or neutral events. |
| For men, low testosterone means high risk of severe COVID-19, study suggests Posted: 25 May 2021 08:37 AM PDT A new study suggests that, among men, low testosterone levels in the blood are linked to more severe COVID-19. The study contradicts widespread assumptions that higher testosterone may explain why men, on average, develop more severe COVID-19 than women do. |
