NewsReview finds no direct link between aluminium adjuvanted vaccines and serious or long term health conditions
Current evidence does not support direct (causal) associations between aluminium adjuvanted vaccines and serious or long term health outcomes, including autism, diabetes and asthma, finds a review of the latest data.

NewsPolymer ‘bristles’ could help repel proteins — and germs — from surfaces in medical settings
A non-toxic coating made of polydimethylsiloxane prevents proteins from sticking to surfaces — potentially offering a new tool in the fight against hospital-acquired infections.

NewsDairy farms in California may transmit H5N1 virus through multiple sources
A new study suggests that avian influenza (H5N1) is transmitted through multiple, previously unknown sources on dairy farms and that some H5N1 positive cows do not show clinical signs of infection.

NewsEarly life on Earth relied on a surprisingly scarce metal
A new study shows that 3.4 billion years ago, life on Earth relied on a metal called molybdenum, despite its limited availability at the time. It is the first to trace molybdenum’s use this far back in time.

NewsJ. Craig Venter, genomics pioneer and founder of JCVI and Diploid Genomics, Inc., dies at 79
The J. Craig Venter Institute (JCVI) has announced that J. Craig Venter, Ph.D., the Institute’s founder, board chair, and chief executive officer, died in San Diego following a brief hospitalization for unexpected side effects that arose from treatment of recently diagnosed cancer.

NewsClimate change increases spillover risk of rodent-borne arenaviruses
Climate change is likely to drive rodent-borne arenaviruses into parts of South America that have never faced these diseases, according to an early risk projection model that incorporated climate projections, shifting rodent populations and the risks of human infection.

NewsModerate UV light is best to boost the vitamin D content of edible mushrooms, study finds
Researchers have discovered that moderate ultraviolet (UV) light exposure is best when the technique is used to enhance vitamin D₂ in edible mushrooms. Excessive exposure leads to nutrient degradation or a plateau effect, they found.

NewsNew study shows cranberry juice may boost UTI antibiotics
Researchers recently exposed lab-grown strains of pathogenic Escherichia coli to cranberry juice. Preliminary findings suggest that compounds in the juice re-sensitize resistant strains to antibiotic treatment.

NewsProviding food baskets to people with tuberculosis is cost-effective and could avert over 100,000 deaths annually in India
Undernutrition is the single greatest modifiable risk factor for tuberculosis (TB). Researchers found that providing food baskets to people with TB and their households may save tens of thousands of lives annually in India if implemented at scale.

NewsAI speeds chemists’ search for better disinfectants
Scientists published their computational-experimental framework for developing quaternary ammonium compounds, or QACs, to kill bacteria. The method yielded 11 new QACs that show activity against antimicrobial-resistant bacteria.

NewsHantavirus cluster linked to cruise ship highlights ongoing zoonotic risk and the need for vigilance
Experts emphasized caution while underscoring the importance of environmental controls, early detection, and clear communication in travel settings.

NewsResearchers identify natural compound that disarms drug-resistant bacteria
Scientists studying MRSA discovered that geranylgeranoic acid (GGA) – a naturally occurring fatty acid found in plants like ginger and turmeric – interferes with the bacteria’s virulence, its ability to infect, spread, defend itself, and cause disease.

NewsStudy finds four of the CDC’s seven measles elimination status indicators missed
After public health experts declared measles eliminated in the U.S. in 2000, the U.S. CDC established seven indicators of measles elimination status to ensure that the country remained on track. Now researchers find that the U.S. missed four of the seven criteria, with the others at risk.

NewsDisease-causing pathogen rewires gut metabolism to secure nutrients for growth
Enterotoxigenic Bacteroides fragilis (ETBF), which causes diarrhea and has been implicated in colitis and colorectal cancer, uses a toxin it produces to reprogram intestinal cell metabolism and generate conditions that support its growth.
-
NewsChanges in CDC communication undermine public trust in vaccines
Exposure to uncertainty-based messaging about vaccines increased perceived vaccine risks and uncertainty, reduced vaccination intentions, lowered trust in the CDC, and increased endorsement of science-denial strategies.

NewsCervical cancer: A growing gap between high- and low-income countries
While high-income countries could eliminate cervical cancer by 2048 through human papillomavirus (HPV) vaccination and screening, the gap with lower-income countries is widening.
-
NewsIn mice, viruses gain virulence in some individuals, depending on genetics and sex
New research demonstrates that some hosts appear to serve as “evolutionary accelerators” that could enable viruses to gain virulence more quickly.
-
NewsAncient, insect-targeting bacterial toxin may have implications for human health, agriculture, and drug discovery
Scientists have identified and characterized a new class of Streptomyces-produced toxins that are very distantly related to the deadly toxin that causes diphtheria, a serious and contagious infection, in humans.

NewsPet cats that roam outdoors carry similar disease risk as feral cats, global study finds
A new study has found that pet cats allowed to roam outside unsupervised carry infectious diseases at rates comparable to feral cats, even when they receive veterinary care, regular meals and shelter.

NewsSignificant rise in valley fever cases in El Paso linked to extreme weather and dust
A new study has identified a significant rise in Valley fever cases in El Paso over the past decade and found strong connections between the disease and extreme weather, wind and airborne dust.
