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

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

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.

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
