People who walk more each day tend to score better on several brain tests

Researchers analyzed 14 years of physical activity and blood pressure records from 3,093 US adults and found that higher daily step counts were associated with better performance on tests of attention, cognitive control, and reward-related decision-making. Higher systolic blood pressure was associated with poorer delay-discounting performance, but accounted for only 4.8% of its association with physical activity, while the single cognitive assessment prevented conclusions about causation or cognitive decline.

Your diet may have more to do with your sense of smell than you think

Researchers analyzed dietary patterns and odor identification in 6,690 adults in Italy, finding that healthier plant-rich diets, particularly those emphasizing fruits and vegetables, were associated with better olfactory function and lower odds of hyposmia. Diets emphasizing less healthy plant foods showed the opposite association, although the cross-sectional study could not establish whether diet influences smell or impaired smell affects food choices.

Cigarette smoke exposure alters ovarian and testicular function in mice

New research has shed light on how exposure to cigarette smoke could affect reproductive health in both men and women, identifying changes in biological processes involved in ovarian function and sperm production.

Scientists studied diet and lung cancer in 95,612 adults. One eating pattern stood out

A prospective study of 95,612 U.S. adults found that those with the highest sulfur microbial diet scores had a 23% higher adjusted lung cancer incidence hazard and a 19% higher lung cancer-related mortality hazard than those with the lowest scores. However, the associations weakened after accounting for overall dietary quality and competing causes of death, and the findings do not establish a causal relationship.

Doctors avoided two common words when talking about weight with patients

Researchers analyzed 123 recorded primary care consultations involving adults with type 2 diabetes and elevated BMI, finding that weight was discussed in just 39% of visits. Clinicians avoided potentially stigmatizing terms such as "overweight" and "obesity," while weight-related conversations occurred more frequently among patients taking GLP-1 receptor agonists.

Nearly 400,000 adults, six body measurements, and a surprising result for heart attack risk

A UK Biobank study involving 395,831 adults found that a higher body roundness index (BRI) was associated with an increased risk of myocardial infarction over a median follow-up of 13.3 years. BRI showed slightly better predictive performance than BMI and four other anthropometric measures, although the improvements were modest and require independent validation before clinical adoption.

Study finds a surprising downside to having favourite foods

In a study of 279 adults, researchers found that initially reinforcing existing food preferences reduced learning flexibility when associations between foods and outcomes changed. Participants learned positive associations more readily than negative ones, while associations involving disliked foods were more adaptable than those involving liked foods.

Who moves first at night, you or your dog?

Researchers monitored 25 adults and 38 dogs and found no significant association between bedsharing and objectively measured human sleep duration or efficiency, although owners of multiple dogs reported poorer sleep quality in an analysis requiring cautious interpretation. Human and dog movements were positively correlated, with human activity more often preceding canine activity among pairs with identifiable associations, although the study could not determine which species drove the other's movements.

Three months of yoga before surgery revealed a surprising difference in stress hormones

In a non-randomized study of 40 adults with severe obesity awaiting bariatric surgery, researchers found significantly lower plasma noradrenaline levels in yoga participants than in controls after adjusting for baseline measurements. The researchers detected no significant DNA methylation changes in three inflammatory genes and found no clear psychological or metabolic benefits.

Researchers followed glucose monitor users for three years and found a possible kidney benefit

A study of more than 25,000 analytical group assignments involving high-risk adults with type 2 diabetes found that sustained real-time continuous glucose monitoring (rtCGM) was associated with substantial improvements in blood sugar control over three years. Continued use was also linked to lower levels of a marker of kidney damage after three years, although researchers found no evidence that the technology preserved kidney filtration function.

Adding a chatbot to specialist care helped young people make sense of cancer risk

In a randomized trial of 106 adolescents and young adults with hereditary cancer predisposition, adding AYA-RISE to a clinic visit improved knowledge of cancer risk before age 30 compared with a clinic visit alone. Researchers observed no increase in distress, but the main analyses did not establish additional benefits for lifetime-risk or screening knowledge.

Diet drinks showed no clear weight-loss edge over water after two years

In a two-year randomized trial combining assisted weight management with an unassisted follow-up year, completers maintained average weight losses of 4.8 kg with diet drinks and 3.7 kg with water. Researchers found no significant difference between groups, but fewer than half of the 493 participants completed follow-up.

What people ate at the start of a 20-year study was linked to their heart failure odds

Researchers linked higher baseline diet quality to lower odds of developing heart failure over 20 years among 2,159 Greek adults initially free of cardiovascular disease. Healthy-food consumption showed the most consistent association, but the observational study cannot establish that dietary changes prevent heart failure.

LSD microdosing linked to improved attention in women but not men

A pilot study suggests that low doses of LSD may have different effects on sustained attention in women and men. The findings, presented at the ECNP annual congress in Munich, are preliminary, but they add to growing evidence that people may not all respond to psychedelic microdosing in the same way.

Stopping GLP-1 drugs often brings weight back. A small trial suggests ways to slow it

In a randomized pilot trial of 39 adults, researchers found that participants receiving medically tailored meals or Noom regained about 3.6% of their body weight over four months after stopping GLP-1 therapy, compared with about 11% under usual care. These exploratory findings suggest structured support may slow early weight regain, but the small sample and short follow-up leave lasting benefits uncertain.

16-year study links worsening vision to higher dementia risk

Researchers followed 15,576 older adults in Hong Kong for up to 16 years and linked moderate to severe visual impairment to higher dementia risk, with rapid visual decline strengthening the association at poorer levels of vision. They estimated that severe impairment corresponded to 2.1 fewer dementia-free years over the study period, but could not establish that correcting vision prevents dementia.

A trial of 3,220 smokers puts cash rewards for quitting to the test

In a randomized trial of 3,220 medically underserved adults referred for lung cancer screening, adding financial incentives to usual care and free medication increased sustained smoking abstinence at six months. Offering free medication alone did not significantly increase quit rates, and adding a forward-looking mobile tool did not improve outcomes beyond the incentives.
