NewsIndy gene reduction linked to healthier gut microbiota and longer lifespan in fruit flies
Scientists investigating aging have shown that Indy reduction is associated with lower bacterial load and higher bacterial diversity in aging Indy flies compared to controls.

NewsLab identifies gap in malaria vaccines, added peptides can strengthen response
The two vaccines in use today rally the immune system against a single region of the malaria parasite. A new study finds that adding short peptides for two overlooked regions broadens the response and strengthens protection.

NewsU.S. disease tracker launches to strengthen monitoring of vaccine-preventable diseases
A new website will track the spread of vaccine-preventable diseases across the United States to offer the public, the media, healthcare providers, public health officials, and policymakers reliable and visual information about current disease trends.

NewsCascading disaster: While U.S. HIV infections have fallen, they are rising among Latinos
From 2010 to 2022, new HIV infections in the United States declined 19% overall but among Latinos, they rose 12%. In 2023, new HIV diagnoses among Latinos jumped 8% in a single year — the largest increase of any racial or ethnic group in the country.

NewsMost cases of HIV persistence in blood following treatment explained by defective copies of the virus
A study based on blood samples strongly suggests that most persistent cases of viral detection, despite ideal HIV drug therapy, are not due to virus transmission or a rebound of active disease.

NewsPhase 1 clinical trial set to begin on first leishmaniasis vaccine
A phase 1 clinical trial testing the safety of a leishmaniasis vaccine is set to begin in the coming months. The live vaccine, found to be safe in animals, is expected to be tested in humans later this year.

NewsFDA approves early warning system for sepsis
An early warning system for sepsis, one of the deadliest infections for hospital patients, has been approved for use by the FDA, one of the first AI-based medical tools to get clearance. The tool detects sepsis hours faster than doctors and has reduced deaths by nearly 20%.

NewsScientists discover how gut bacteria toxin invades colon cells to trigger cancer
A common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of the colon. Researchers have now shown that the B. fragilis toxin BFT must first bind host receptor claudin-4 before it can cause damage.

NewsWhere people get their news influences their beliefs about vaccines
People who follow “new right” media outlets are more than twice as likely to be vaccine-hesitant compared to those who never engage with those outlets, a new study finds. Hesitant adults were more likely to rely on non-authoritative sources for health information.

NewsScientists warn antibacterial soaps and wipes can fuel antimicrobial resistance
An international team of scientists is warning that everyday antibacterial soaps, wipes, sprays, and other “germ‑killing” products are quietly contributing to the global rise of antimicrobial resistance (AMR) while providing no added health benefit for most consumer uses.

NewsLife forms can planet hop on asteroid debris – and survive
The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid impact, a study shows. It means microorganisms can survive more extreme conditions than previously thought, including launch across space after major impacts.

NewsOlder age, chronic kidney disease and cerebrovascular disease linked with increased risk for paralysis and death after West Nile virus infection
Older people with a history of chronic kidney disease or conditions affecting blood flow to the brain such as stroke face about double the risk for developing neuroinvasive disease that can lead to paralysis and death following infection with West Nile virus, new research finds.

NewsMalaria parasites move on right-handed helices
After penetrating the skin, the malaria parasite moves with helical trajectories, almost always turning toward the right. Researchers demonstrated that the pathogen uses these right-handed helices to control its motion as it transitions from one tissue compartment to another.

NewsGroundbreaking new projects launched to lower the cost of monoclonal antibody production
LifeArc and the Gates Foundation have awarded more than $5m to seven projects aimed at developing cheaper and more efficient ways to produce monoclonal antibody (mAb) treatments. The innovative approaches include using filamentous fungus to produce mAbs.

NewsStudy finds COVID-19 mRNA vaccine sparks immune response to fight cancer
Patients with advanced lung or skin cancer who received a COVID-19 mRNA vaccine within 100 days of starting immunotherapy drugs lived significantly longer than those who did not get the vaccine, researchers have found.

NewsStealth genetic switch in mosquitoes halts malaria spread
Biologists have created a CRISPR-based gene-editing system that changes a single molecule within mosquitoes, stopping the malaria-parasite transmission process. Genetically altered mosquitoes are still able to bite those with malaria, but the parasites can no longer be spread to other people.

NewsMediterranean bacteria may harbor new mosquito solution
Researchers recently identified bacteria in Crete producing metabolites that quickly kill mosquito larvae in lab tests. The compounds might be useful for the development of new biopesticides, though developing the right formulations and delivery method remains a challenge.

NewsNew AI reimagines infectious disease forecasting
A new AI tool to predict the spread of infectious disease outperforms existing state-of-the-art forecasting methods. The tool could revolutionize how public health officials predict, track and manage outbreaks of infectious diseases including flu and COVID-19.

NewsNew data shows MMR vaccination rate decline across US
A new county-level dataset reveals a national decline in the measles-mumps-rubella (MMR) vaccination rate among U.S. children since the start of the COVID-19 pandemic.
