How E. coli eavesdrops on the metabolic activity of other gut bacteria

22 hours 59 minutes ago
The gut microbiome is teeming with hundreds of bacterial species and trillions of bacteria. These microorganisms influence many aspects of health, including digestion, and assist with numerous functions in the body. Gut bacteria compete for the limited nutrients available in their environment, while also interacting with each other in ways that can influence the stability of the microbial community.

Scientists identify avian cholera as major cause of penguin deaths in Antarctica

23 hours 29 minutes ago
Thousands of Adélie penguins found dead in Antarctica in 2024 were primarily victims of avian cholera, not high pathogenicity avian influenza (H5N1) as researchers initially suspected, according to a study published today in Proceedings of the Royal Society B: Biological Sciences. The findings highlight an underrecognized threat to Antarctic wildlife and the importance of comprehensive disease investigations, particularly as H5N1 continues to raise concerns for seabird and marine mammal populations.

Engineered enzyme could improve detection of HIV and other viruses

23 hours 39 minutes ago
Scientists have long used a powerful gene-editing tool called CRISPR to make precise changes to DNA. But a different version of the technology, known as Cas13a, targets RNA, the genetic material found in viruses such as HIV. Now, researchers at Rice University have developed an improved version of Cas13a that could make it easier to detect HIV and other RNA viruses in blood and environmental samples. The study was published in Cell Chemical Biology.
