| Scientists find brain network that makes mice mingle Posted: 15 Mar 2022 08:29 AM PDT The difference between a social butterfly and a lone wolf is actually at least eight differences, according to new findings by a team of brain researchers. By simultaneously spying on the electrical activity of several brain regions, researchers can both identify how social or solitary an individual mouse is, and, by zapping nodes within this social brain network, can prompt mice to be even more gregarious. |
| 'Long COVID' linked to lasting airways disease Posted: 15 Mar 2022 07:56 AM PDT Disease of the small airways in the lungs is a potential long-lasting effect of COVID-19, according to a new study. The study found that small airways disease occurred independently of initial infection severity. The long-term consequences are unknown. |
| People with diabetes who eat less processed food at night may live longer Posted: 15 Mar 2022 06:50 AM PDT The time of day that people with diabetes eat certain foods may be just as important to their well-being as portion size and calories, according to a new study. |
| Elevated inflammation persists in immune cells months after mild COVID-19 Posted: 15 Mar 2022 06:50 AM PDT There is a lack of understanding as to why some people suffer from long-lasting symptoms after COVID-19 infection. A new study now demonstrates that a certain type of immune cell called macrophages show altered inflammatory and metabolic expression several months after mild COVID-19. |
| Posted: 15 Mar 2022 06:50 AM PDT A new study has found that oil palm can be farmed more sustainably on peatlands by re-wetting the land - conserving both biodiversity and livelihoods. |
| Discovery of novel brain fear mechanisms offers target for anxiety-reducing drugs Posted: 15 Mar 2022 06:50 AM PDT A new target in the brain which underpins the eliciting of anxiety and fear behaviors such as 'freezing' has been identified by neuroscientists. Researchers say the discovery of a key pathway in the brain offers a potential new drug target for treating anxiety and psychological disorders, which affect an estimated 264-million people worldwide. |
| Hoverfly brains mapped to detect the sound of distant drones Posted: 15 Mar 2022 06:49 AM PDT Researchers have reverse engineered the visual systems of hoverflies to detect drones' acoustic signatures from almost four kilometers away. The finding could help combat the growing use of IED-carrying drones, including those used in Ukraine. |
| Climate scientists reconsider the meaning and implications of drought in light of a changing world Posted: 14 Mar 2022 03:15 PM PDT Maps of the American West have featured ever darker shades of red over the past two decades. The colors illustrate the unprecedented drought blighting the region. In some areas, conditions have blown past severe and extreme drought into exceptional drought. But rather than add more superlatives to our descriptions, one group of scientists believes it's time to reconsider the very definition of drought. |
| Ready, set…GO! Scientists discover a brain circuit that triggers the execution of planned movement Posted: 14 Mar 2022 03:15 PM PDT Planned movement is essential to our daily lives, and it often requires delayed execution. As children, we stood crouched and ready but waited for the shout of 'GO!' before sprinting from the starting line. As adults, we wait until the traffic light turns green before making a turn. New research explores how cues in our environment can trigger planned movement. |
| Fast-melting alpine permafrost may contribute to rising global temperatures Posted: 14 Mar 2022 03:14 PM PDT Using lake sediment in the Tibetan Plateau, a team of researchers was able to show that permafrost at high elevations is more vulnerable than arctic permafrost under projected future climate conditions. |
| Cognitive decline key factor in predicting life expectancy in Alzheimer’s disease Posted: 14 Mar 2022 03:14 PM PDT Cognitive decline is the biggest factor in determining how long patients with Alzheimer's disease will live after being diagnosed, according to a new study. |
| Malaria drug could combat chemotherapy-resistant head and neck cancers, research suggests Posted: 14 Mar 2022 12:44 PM PDT A new study suggests that the malaria drug hydroxychloroquine inhibits pathways that drive resistance to the chemotherapy agent cisplatin in head and neck cancers and restores tumor-killing effects of cisplatin in animal models. |
| Are conferences worth the time and money? Posted: 14 Mar 2022 11:20 AM PDT Scientists who interact with others during assigned sessions at conferences are more likely to form productive collaborations than scientists who do not, researchers found. And the kicker? It doesn't matter whether the conference is in person or virtual. |
| Warning: Objects in driverless car sensors may be closer than they appear Posted: 14 Mar 2022 11:20 AM PDT Researchers have demonstrated the first attack strategy that can fool industry-standard autonomous vehicle sensor components into believing nearby objects are closer (or further) than they appear without being detected. The research suggests that adding optical 3D capabilities or the ability to share data with nearby cars may be necessary to fully protect autonomous cars from attacks. |
| A third of new moms during early COVID had postpartum depression Posted: 14 Mar 2022 11:20 AM PDT One in three new mothers during early COVID-19 screened positive for postpartum depression -- nearly triple pre-pandemic levels -- and 1 in 5 had major depressive symptoms, say researchers. |
| Physicist shed light on the darkness Posted: 14 Mar 2022 09:07 AM PDT Experimental physicists have succeeded for the first time in controlling protected quantum states - so-called dark states - in superconducting quantum bits. The entangled states are 500 times more robust and could be used, for example, in quantum simulations. The method could also be used on other technological platforms. |
| Link between high cholesterol and heart disease 'inconsistent', new study finds Posted: 14 Mar 2022 09:07 AM PDT New research has revealed that the link between 'bad' cholesterol (LDL-C) and poor health outcomes, such as heart attack and stroke, may not be as strong as previously thought. |
| Metastatic prostate cancer on the rise since decrease in cancer screenings Posted: 14 Mar 2022 09:07 AM PDT A new study finds that the incidence rate of metastatic prostate cancer has significantly increased for men 45 and older and coincides with recommendations against routine prostate cancer screenings. |
| Huge forest fires don't cause living trees to release much carbon, research shows Posted: 14 Mar 2022 09:06 AM PDT Research on the ground following two large wildfires in California's Sierra Nevada mountain range showed the vast majority of carbon stored in trees before the blazes was still there after the fires. |
| Photo or the real thing? Mice can inherently recall and tell them apart Posted: 14 Mar 2022 06:57 AM PDT The ability to make perceptual and conceptual judgements such as knowing the difference between a picture of an object and the actual 3D object itself has been considered a defining capacity of primates, until now. A study provides the very first behavioral evidence that laboratory mice are capable of higher-order cognitive processes. Findings also provide strong support that the mouse's hippocampus, like that of humans, is required for this form of nonspatial visual recognition memory and picture-object equivalence. |
| Air pollution linked to depressive symptoms in adolescents Posted: 14 Mar 2022 06:56 AM PDT Exposure to ozone from air pollution has been linked to an increase in depressive symptoms for adolescents over time, even in neighborhoods that meet air quality standards, according to new research. |
