Tea, tap water and child IQ: What a Canadian pregnancy study found

Researchers analyzed 485 mother-child pairs in Canada to examine whether estimated fluoride intake from tea during pregnancy was associated with IQ at ages 3 to 4. Each 0.5 mg/day increase was associated with a 2.24-point lower full-scale IQ score, although the observational design and estimated exposure prevent causal conclusions.

Hydrogen-powered shipping could deliver $284 billion in annual health benefits

Researchers modeled how replacing conventional global shipping fuels with hydrogen could change PM2.5 and ozone pollution, premature mortality, and monetized health benefits. Under complete transition, the model estimated 129,458 fewer premature deaths and US$284 billion in annual monetized health benefits, although some regions experienced increased pollution from hydrogen production or altered ozone chemistry.

Insilico unveils standardized evaluation framework to validate AI-driven drug discovery models

As general-purpose and domain-specific AI models rapidly infiltrate drug discovery, one critical question looms over the pharmaceutical sector: Can these models actually discover drugs, or are they just good at taking tests?

Pork supply chains may be shaping the global spread of drug-resistant Salmonella

Researchers linked 129,136 global human and swine Salmonella genomes with sampling from a Guangdong pork supply chain to examine how downstream stages relate to antimicrobial resistance. The study suggests slaughterhouse and retail interfaces may concentrate S. 4,[5],12:i:- ST34, resistant strains, and mobile resistance elements, supporting broader One Health surveillance beyond farms.

Biotherapeutic metabolite repairs gut damage caused by HIV infection

Researchers at the UC Davis School of Medicine have identified a naturally occurring metabolite that repairs gut damage caused by HIV infection and significantly improves the effectiveness of antiretroviral therapy (ART) in the nonhuman primate model of HIV/AIDS.

Microbial metabolites could help improve functional cure rates for hepatitis B

Chronic hepatitis B (CHB) remains a major global challenge. Current therapies suppress HBV but rarely achieve functional cure (sustained HBsAg loss).

Cigarette smoke extract primes airway cells for greater nanoplastic damage

Researchers found that cigarette smoke extract weakened epithelial barriers and increased the proportion of human airway cells that were polystyrene nanoparticle-positive. Sequential treatment caused greater metabolic disruption and increased mucus-producing cells, suggesting heightened epithelial vulnerability, although the findings are limited to in vitro models.

Discovery of calcium channel mechanism offers clues for brain disorder treatments

DGIST (President Kunwoo Lee) announced that a research team led by Professor Byung Chang Suh of the Department of Brain Sciences has, for the first time, uncovered a novel molecular mechanism that regulates the "N-type voltage-gated calcium channel (CaV2.2)," which plays a critical role in neural signal transmission.

Research offers a promising way to develop potent antivenoms against deadly snakebites

University of Maryland researchers discovered a new approach to treating venomous snake bites-using the same toxin-blocking proteins that snakes evolved to protect themselves.

Scientists uncover how muscle actin filaments grow and renew themselves

Biophysicists unraveled a mystery of how muscles form at the molecular level and how they maintain their function.

Researchers train AI to detect diabetes and assign four diagnostic labels

Researchers developed a two-stage machine learning framework that detected diabetes and classified records as prediabetes, type 1, type 2, or type 3c diabetes using two public datasets. XGBoost showed strong internal performance, but inconsistent model rankings, non-standard variables, and the absence of external clinical validation limit immediate use.

Scientists discover why bats survive deadly viruses without getting sick

It is a mystery that has puzzled scientists for years. How can the world's only winged mammals carry viruses that cause severe disease while rarely becoming seriously ill themselves?

Photoreceptors possess internal recycling system to preserve vision

For decades, scientists believed that photoreceptors in the retina relied primarily on neighboring support cells, known as the retinal pigment epithelium (RPE), to remove waste. While the RPE is still responsible for clearing away the worn-out tips of photoreceptors each day, new findings from the University of Oklahoma reveal that photoreceptors also perform much of their own internal housekeeping.
