Bacterial strains determine pneumonia and meningitis risk from air pollution

Air pollution leads to different risk of bacterial pneumonia, sepsis, and meningitis, depending on the subtype of bacteria a person has, new research suggests.

KAIST team uncovers how neurons deliver RNA to distant regions

Much like a courier reading an address on a package, neurons must deliver RNA to the precise locations where it is needed.

A study of more than 21,000 adults found an unusual link between psilocybin and diet

Using data from more than 21,800 adults in two UK birth cohorts, researchers found that lifetime psilocybin and LSD use was associated with stronger pro-environmental attitudes and a greater likelihood of following a vegetarian diet, with psilocybin showing the clearer dietary pattern. Mediation analyses suggested that environmental attitudes statistically accounted for the psilocybin-vegetarianism association and part of the association with lower red meat consumption, but the observational design cannot establish causation.

An 8-hour eating window stood out for weight loss, but the full picture is more complicated

A pooled analysis of individual data from five time-restricted eating trials involving 124 adults linked shorter eating windows with modestly greater weight loss. Eight-hour TRE was associated with greater weight loss than 12-hour TRE and controls, while cardiometabolic outcomes showed no consistent relationship with eating-window duration and several weight associations weakened after adjustment.

Like your tea or coffee very hot? A study of nearly 1 million adults found a striking cancer link

In pooled prospective data from 977,282 UK adults, preferring tea or coffee “very hot” was associated with more than threefold higher risk of esophageal squamous cell carcinoma compared with preferring drinks “warm,” while drink temperature showed no material association with adenocarcinoma risk. Consuming six or more hot drinks daily was independently associated with higher squamous cell carcinoma risk, and modeling estimated that about 440 UK cases each year could be prevented by switching from “very hot” to “hot” drinks if the association is causal.

Researchers changed the music in a cafeteria. Food choices shifted too

Across one cafeteria field experiment and three scenario-based studies, low-arousal background music was associated with a higher proportion of healthy food selections or stronger intentions to consume healthy foods than high-arousal music. In the scenario studies, perceived comprehension helped explain the relationship, while the final experiment found that both music conditions produced stronger healthy-food intentions than restaurant noise alone, with low-arousal music showing the greater benefit.

More data, more answers? A 1.9 million-person health study shows why scale has limits

Researchers analyzed phenotypic and linked health-record data from more than 1.9 million adults in Our Future Health, comparing demographic characteristics, disease patterns, clinical associations, and rare-condition case counts with national data and other major cohorts. The cohort's size provides unusually large samples for many common and less common conditions, although its demographic composition and current data sources require careful consideration when interpreting population-level estimates.

APOE genotype helps p-tau217 predict who may develop cognitive impairment sooner

A pooled analysis of 8,582 adults from seven prospective cohorts found that higher plasma p-tau217 concentrations were associated with greater cognitive impairment risk and earlier progression, with stronger associations among APOE-ε4 carriers. Each 1-SD increase in p-tau217 was associated with a 24% shorter time to cognitive impairment among carriers compared with 13% among non-carriers, suggesting that genetic background can refine the prognostic meaning of this Alzheimer’s disease blood biomarker.

A study of ayahuasca users found a mental health pattern researchers cannot yet explain

In a cross-sectional study of 808 Brazilian adults planning to attend ayahuasca ceremonies, greater prior experience with the brew was associated with lower depression, anxiety, and stress scores, as well as higher spiritual well-being and stronger metaphysical beliefs. Because the study was observational and relied on self-reported data, it cannot show that ayahuasca caused these differences.

Cockroaches have a reputation for surviving almost anything, but this diet proved deadly

A laboratory study tested how ultra-processed, unprocessed, and mixed diets affected survival in 127 lobster cockroaches, Nauphoeta cinerea. Cockroaches fed only ultra-processed foods had higher mortality than those given unprocessed or mixed diets, although the study could not determine whether processing, ingredients, nutrition, or differences in food intake caused the effect.

Neoadjuvant atezolizumab addition quadruples pathological responses in resectable lung tumors

Patients with resectable stage II–IIIB non-small cell lung cancer (NSCLC) treated with perioperative atezolizumab plus platinum-based chemotherapy experienced a median event-free survival of 62.8 months compared with 34.9 months for patients receiving chemotherapy alone, according to final results from the Phase 3 IMpower030 trial.

Rare cortical neurons actively promote the transition into sleep

What makes the brain fall asleep? For nearly a century, scientists have looked to structures deep within the brain for the answer.

New dendritic constrictions reveal hidden complexity in neuronal signaling

Neurons receive thousands of signals via tree-like extensions called dendrites. Until now, these dendrites were thought to be relatively smooth cables that conduct electrical signals to the cell body.

Video game offers new insights into autistic perception

People with autism often come at life from a different angle-seeing details others miss, focusing on patterns rather than faces, experiencing heightened or dimmed physical sensations.

Targeted nanoparticles strengthen anti-cancer immune responses in tumors

Adelaide University researchers have developed a new way of using mRNA technology to reprogram tumor-supporting immune cells and strengthen the body's anti-cancer immune response.

Obesity suppresses natural protection against breast cancer growth

A research team at Huntsman Cancer Institute at the University of Utah (the U) has found that obesity prevents a biological process that kills cancerous cells, revealing a possible reason why obesity is a risk factor for breast cancer.
