NewsBoosting plant health: the role of gene exchange with bacteria
Scientists have discovered 75 genes that were transferred between small, fast-growing plants (Arabidopsis thaliana) and its bacterial companions, influencing key processes like carbohydrate metabolism and hormone synthesis.

NewsIsolated viral load test may generate false positive results for people using long-acting PrEP
A single laboratory-based HIV viral load test used by U.S. clinicians who provide people with long-acting, injectable cabotegravir (CAB-LA) HIV pre-exposure prophylaxis (PrEP) did not reliably detect HIV in a multi-country study.

NewsNew study confirms mammal-to-mammal avian flu spread
A new study provides evidence that a spillover of avian influenza from birds to dairy cattle across several U.S. states has now led to mammal-to-mammal transmission – between cows and from cows to cats and a raccoon.

NewsStudy finds how common skin bacterium causes chronic infections after orthopedic surgeries
Scientists investigating chronic bone infections have found that the common skin bacteria Cutibacterium acnes can persist as layers of biofilms for weeks on contaminated titanium or stainless-steel implants.

NewsHIV vaccines tested in PrEPVacc fail to reduce infections
The results of the PrEPVacc HIV vaccine trial conducted in Eastern and Southern Africa, which ran between 2020 and 2024, show that neither of the two experimental vaccine regimens tested reduced HIV infections among the study population.

NewsSARS-CoV-2 pandemic increases maternal deaths from non-respiratory causes, study finds
A new study revealed a significant impact of the COVID-19 pandemic on maternal mortality in Chile. The pandemic did not affect direct obstetric deaths such as hemorrhage, sepsis and abortion, but non-respiratory indirect obstetric causes increased the most.

NewsPeptide cocktails could be key to fighting antibiotic resistance
A new study highlights the potential of random antimicrobial peptide mixtures to significantly reduce the risk of resistance evolution compared to single peptides, emphasizing the need for innovative solutions to outpace bacterial resistance and safeguard health.

NewsIt’s not just humans — bacteria have memory too
Beneficial bacteria — used in probiotics and biological pest control to fight harmful bacteria — possess memory, and even pass information on to future generations.

NewsExpiring medications could pose challenge on long space missions
Medications commonly used by astronauts aboard the International Space Station might be ineffective or harmful on a multi-year mission to Mars, a new study suggests.

NewsNew drug target identified for diseases associated with leukemia-causing virus
Researchers have found a new target for treating diseases associated with human T-cell leukemia virus type 1 (HTLV-1). Blocking kinases, which regulate cellular functions, leads to cell death caused by the degradation of the protein Tax.

NewsMutations of the spike gene do not predict the severity of variants of SARS-CoV-2
The two recent and prevalent strains of the virus that cause COVID-19 are not significantly better than their predecessor Omicron at evading immune responses and causing infections despite having a higher number of mutations.
