| Can supermarkets coax people into buying healthier food? Posted: 24 Mar 2022 11:37 AM PDT Restricting supermarket placement of less healthy items and increasing the availability of healthier alternatives in these stores may be promising interventions to encourage healthier purchasing behaviors, according to two new studies. |
| Tuberculosis infection protects mice from developing COVID-19 Posted: 24 Mar 2022 11:37 AM PDT In mice, the immune response mounted against tuberculosis prevents them from developing COVID-19, according to a new study. |
| Tuberculosis induces premature cellular aging Posted: 24 Mar 2022 10:03 AM PDT Researchers found that the cells of humans and animals who have recovered from tuberculosis had prematurely aged up to 12 to 14 years. It's possible that this premature cellular aging is one reason why survivors of tuberculosis have a high risk of mortality. |
| Blow flies can be used detect use of chemical weapons, other pollutants Posted: 24 Mar 2022 10:02 AM PDT A study suggests blow flies could be used to detect the use of chemical weapons -- as well as other dangerous substances -- in areas too dangerous or remote for human investigators. |
| Resourceful viral protein combats monkey and human defenses differently Posted: 24 Mar 2022 09:26 AM PDT Researchers have found that different parts of viral protein U expressed by simian immunodeficiency virus are required to bind to and block tetherin, an antiviral protein, in monkey cells versus in human cells. This suggests that the virus uses two different mechanistic strategies to evade this host defense and sheds new light on host-pathogen coevolution. |
| Popular male dolphins produce more offspring Posted: 24 Mar 2022 09:25 AM PDT The reproductive success of male dolphins is not determined by strength or age, but via social bonds with other males. The better integrated males are in their social network, the more offspring they produce, a new study has shown using long-term behavioral and genetic data. |
| Membraneless organelles: From liquid to solid to drive development Posted: 24 Mar 2022 07:45 AM PDT Researchers show that transition from liquid to solid is important for the function of membraneless organelles. |
| Indian forest loss 'worse than feared' due to climate change Posted: 24 Mar 2022 07:45 AM PDT A national-scale study of the relationship between forest loss and rainfall and temperature trends in India reveals climate change may have contributed to huge declines during last two decades, countering official reports that suggest small losses, and adding to existing concerns over deforestation. |
| Student researchers improve coral restoration efforts Posted: 24 Mar 2022 07:45 AM PDT A recent study revealed that exposing rice coral larvae to warmer temperatures did not improve survival once the coral developed into juveniles and were exposed to heat stress. |
| Remote Indian Ocean reefs bounce back quickly after bleaching Posted: 24 Mar 2022 07:44 AM PDT Coral reefs in remote or protected areas can recover quickly after mass coral bleaching events, new research shows. |
