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.
-
NewsPlankton model bridges the rules of life at individual scale and ecosystem level
Researchers have developed a model that connects microscopic biology to macroscopic ecology, which could deepen our understanding of nature’s laws and create new opportunities in ecosystem management.
-
NewsStudy reveals accelerated aging in women living with HIV
Women with HIV experience accelerated DNA aging, a phenomenon that can lead to poor physical function, according to a new study.

News‘Pink berries’ reveal how bacteria survive a viral epidemic
Like humans struggling to get through the COVID-19 pandemic, bacterial cells need social distancing to thwart viruses. But in some situations, such as inside elevators or within the candy-colored bacterial structures known as “pink berries,” staying apart just isn’t feasible. Source: Lizzy Wilbanks “Pink berry” bacterial structures. These ...

NewsMIssing gut microbes could be the reason why sugar-free candy may give you gas
Researchers have identified changes in the gut microbiome that can result in an inability to digest sorbitol.

NewsScientists home in on viruses that can help ‘dial up’ carbon capture in the sea
Scientists are now zeroing in on the viruses most likely to combat climate change by helping trap carbon dioxide in seawater or, using similar techniques, different viruses that may prevent methane’s escape from thawing Arctic soil.

NewsRare case of opossum infected by rabies sounds alarm for urban environments
The opossum was found dead in a park in the center of Campinas, a large city in São Paulo state (Brazil), with the same viral variant as fruit-eating bats. These mammals are regularly detected in cities, where they are often attacked by dogs.

NewsMethane emissions from wetlands increase significantly over high latitudes
A research team analyzed wetland methane emissions data across the entire Boreal-Arctic region and found that these emissions have increased approximately nine percent since 2002.

NewsBacterial metabolite activates another species to produce bad breath
Researchers find that a metabolite produced by the commensal oral bacterium Streptococcus gordonii activates another bacterial species, Fusobacterium nucleatum, to produce the malodorous compound methyl mercaptan.
