NewsUptake of HIV prevention medication doubles with mix of digital health interventions
A combination of interventions of one-on-one telehealth coaching, peer support forums, and automated text messages more than doubled the use of the HIV prevention strategy, called PrEP, among younger, at-risk Americans.

NewsStudy finds high number of persistent COVID-19 infections in the general population
A new study has found that a high proportion of SARS-CoV-2 infections in the general population lead to persistent infections lasting a month or more, with some of these showing a high number of mutations.
-
NewsBat mating swarms may be the key to solving the next pandemic
The evolution of viral tolerance in Myotis bats may help scientists prevent future pandemics, say researchers.
-
NewsFatty acid produced by gut bacteria directly influences fat metabolism in animals
Researchers investigating gut bacteria that produce fatty acids with a special chemical structure, known as a cyclopropane ring, showed that these can be converted into signals that turn on fat desaturation in the nematode C. elegans.

NewsDroughts may trigger HIV transmission increase among women in rural sub-Saharan Africa
Droughts have the potential to increase the spread of HIV for women living in rural parts of Africa, researchers at the University of Bristol have found.
-
NewsFungi that live in healthy plants are sensitive to climate change
Findings more than a decade in the making reveal a rich diversity of beneficial fungi living in boreal forest trees, with implications for the health of forests.
-
NewsMicrobiome studies explore why more women develop Alzheimer’s disease
Two new studies from the University of Chicago investigate the roles of the gut microbiome and estrogen in the differing rates of Alzheimer’s disease among women and men.
-
NewsSurge in gonorrhoea cases in Denmark: up by 46% between 2021 and 2022
An observed rise in gonorrhoea cases particularly affected younger women and men who have sex with women, indicating a potential shift in infection and transmissibility dynamics across the country.
-
NewsResearchers ID decline in microbial genetic richness in the western Arctic Ocean
Small but statistically significant results point to the need for future study, say David Walsh and Arthi Ramachandran.
-
NewsStudy identifies surge in antibiotic-resistant typhoid
Researchers used whole genome sequencing to identify that S Typhi isolates with mutations evolved locally from the endemic S Typhi population in Blantyre, Malawi, and were not the result of importations from other countries.
-
NewsScientists reveal what makes ‘bad’ bacteria life-threatening
Researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic resistance.
-
NewsPhotosynthetic mechanism of purple sulfur bacterium adapted to low-calcium environments revealed
Researchers revealed the LH1-RC structures of Allochromatium vinosum, a model species of autotrophic bacteria capable of thriving in low-calcium or soft-water environments, at a resolution that enabled individual amino acid visualization.
-
NewsPD-1-enhanced DNA vaccine achieves 6-year cART-free AIDS prevention and virologic control
Researchers have found that PD-1-enhanced DNA vaccination can induce sustained virus-specific CD8+ T cell immunity in an AIDS monkey model.

NewsStudies find flu vaccines were effective in 2022-2023 flu season
Two recent studies have found that flu vaccines were effective for all ages against both moderate and severe flu in the U.S. during the 2022-2023 flu season.
-
NewsResearchers discover that blocking an essential nutrient inhibits malaria parasite growth
Researchers have found that by preventing the malaria parasite from scavenging fatty acids, a type of required nutrient, it can no longer grow.
-
NewsStudy shows rapid antigen COVID-19 tests done at home are reliable
Researchers report that a rapid antigen test (RAT) for detecting SARS-CoV-2, the virus that causes COVID-19, can be used at home with accuracy comparable to the same test being administered by a health care professional.

NewsResearch reveals how lenacapavir pushes HIV capsid to breaking point
Researchers have uncovered the details of how the novel drug lenacapavir works to stop the virus in its tracks. The molecular mechanisms that they uncovered could help to refine and design more effective anti-viral therapies.
-
News New trial highlights incremental progress towards a cure for HIV-1
A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them.
-
NewsInteractions between flu subtypes predict epidemic severity more than virus evolution
An analysis of influenza virus evolution over 22 years of flu seasons reveals the major drivers of disease transmission and epidemic severity.

NewsDigestive mucus could pave way to non-invasive gut tests
New research could make monitoring gut health easier and less painful by tapping into a common—yet often overlooked—source of information: the mucus in our digestive system that eventually becomes part of fecal matter.
