| COVID-19 transmission rare in schools with masking, distancing, contact tracing, study finds Posted: 19 Mar 2021 09:55 AM PDT Wearing masks, social distancing and frequent hand-washing have kept in-school COVID-19 transmission low, according to results of a pilot study in Missouri aimed at identifying ways to keep elementary and secondary schools open and safe during the pandemic. |
| Stroke risk higher than expected among COVID-19 patients Posted: 19 Mar 2021 09:55 AM PDT Analysis of data from the American Heart Association's COVID-19 CVD Registry of more than 20,000 U.S. adults hospitalized with COVID-19 through November 2020 found that, overall, COVID-19 patients had an increased risk of stroke compared with patients who had influenza or sepsis. COVID-19 patients with ischemic stroke were more likely to be older, male, Black race or have high blood pressure, Type 2 diabetes or an irregular heartbeat. |
| Posted: 19 Mar 2021 09:55 AM PDT An international research collaboration has used an omnidirectional camera attached to humpback whale to reveal how these creatures rest underwater. These findings demonstrate how wide-angle lens cameras can be useful tools for illuminating the ecology of difficult-to-observe animals in detail. |
| Substantially higher burden of COVID-19 compared to flu, new research shows Posted: 19 Mar 2021 09:54 AM PDT A new study compares the impact of COVID-19 on patients and hospital resources versus the impact of influenza. |
| Eating before 8:30 a.m. could reduce risk factors for type 2 diabetes Posted: 18 Mar 2021 06:16 AM PDT People who start eating before 8:30 a.m. had lower blood sugar levels and less insulin resistance, which could reduce the risk of developing type 2 diabetes, according to a new study. |
| Facial recognition ID with a twist: Smiles, winks and other facial movements for access Posted: 18 Mar 2021 05:55 AM PDT Concurrent Two-Factor Identity Verification requires both one's facial identity and a specific facial motion to gain access. To set it up, a user faces a camera and records a short 1-2 second video of either a unique facial motion or a lip movement from reading a secret phrase. The video is then input into the device, which extracts facial features and the features of the facial motion, storing them for later ID verification. |
| Cancer survivors face elevated heart disease risk Posted: 17 Mar 2021 03:16 PM PDT A new study has found that about that 35% of Americans with a cancer history had an elevated risk of cardiovascular disease in the next decade, compared with about 23% of those who didn't have cancer. |
| How environmental exposures before conception may impact fetal development Posted: 17 Mar 2021 03:16 PM PDT A new report suggests older age and alcohol consumption in the year leading up to conception may have an impact by epigenetically altering a specific gene during development of human eggs, or oocytes. Although the study did not determine the ultimate physical effects of this change, it provides important insights into the intricate relationship between environmental exposures, genetic regulation and human development. |
| Polystyrene waste is everywhere Posted: 17 Mar 2021 03:16 PM PDT Scientists have discovered a green, low-energy process to break down polystyrene, a type of plastic that is widely used in foam packaging materials, disposable food containers, cutlery, and many other applications. |
| Posted: 17 Mar 2021 12:52 PM PDT The giraffe is a truly puzzling animal. With its exceptional anatomy and suite of evolutionary adaptations, the giraffe is an outstanding case of animal evolution and physiology. Now, researchers have produced a high-quality genome from the giraffe and investigated which genes are likely to be responsible for its unique biological features. |
| Algae growing on dead coral could paint a falsely rosy portrait of reef health Posted: 17 Mar 2021 12:51 PM PDT Algae colonizing dead coral are upending scientists' ability to accurately assess the health of a coral reef community, according to new work from a team of marine science experts. |
| Identifying cells to better understand healthy and diseased behavior Posted: 17 Mar 2021 11:17 AM PDT Neuroscientists, using existing tools such as graphical models, can better identify cells in the brain. The algorithm has major implications for developmental diseases like Alzheimer's since once scientists can understand the mechanism of a disease, they can find interventions. The algorithm greatly accelerates the speed of analyzing whole-brain data and supports crowdsourcing where the larger neuroscience community can test the algorithm and build atlases. |
| Mitigating impact of artificial light at night in tropical forests Posted: 17 Mar 2021 11:16 AM PDT Artificial light at night (ALAN) is a major factor in global insect decline. Scientists found that using amber-colored filters to remove the blue spectra of light from 'warm white' LED (light-emitting diode) lamps drastically reduces insect attraction to nocturnal lighting in a tropical forest. |
| Feeding cattle seaweed reduces their greenhouse gas emissions 82 percent Posted: 17 Mar 2021 11:16 AM PDT A bit of seaweed in cattle feed could reduce methane emissions from beef cattle as much as 82 percent, according to new findings from researchers at the University of California, Davis. |
| Inexpensive tin packs a big punch for the future of supercapacitors Posted: 17 Mar 2021 11:16 AM PDT A sustainable, powerful micro-supercapacitor may be on the horizon, thanks to new research. Until now, the high-capacity, fast-charging energy storage devices have been limited by the composition of their electrodes -- the connections responsible for managing the flow of electrons during charging and dispensing energy. Now, researchers have developed a better material to improve connectivity while maintaining recyclability and low cost. |
| Cellular benefits of gene therapy seen decades after treatment Posted: 17 Mar 2021 11:16 AM PDT Researchers have shown that the beneficial effects of gene therapy can be seen decades after the transplanted blood stem cells has been cleared by the body. |
