Does the type of hand sanitizer matter? A study involving 568 people suggests it might

In a 72-day randomized trial involving 568 participants in Japan, an experimental hand sanitizer containing ethanol, benzalkonium chloride, and lactic acid was associated with a 40% lower cumulative incidence of upper respiratory symptoms than a commercial ethanol-based sanitizer. Participants using the experimental formulation also experienced fewer illness-related work restrictions, although infections were not laboratory-confirmed and the proposed residual antimicrobial mechanism was not directly tested.

Sex hormones dictate how skin stem cells renew themselves

For a long time, differences between females and males were mainly associated with the reproductive organs. Yet organs that have nothing to do with reproduction, such as the skin, can also be shaped by sex.

Toxic forever chemicals detected in New Jersey tap and bottled water

Researchers at New Jersey Institute of Technology (NJIT) have found that a largely overlooked class of "forever chemicals" is widespread in New Jersey drinking water and commercially available bottled beverages, raising new questions about how these persistent contaminants are monitored and potentially introduced into everyday products.

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.

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.

Hybrid AI architecture improves seizure prediction using EEG signals

Epilepsy affects about 50 million people worldwide and can seriously affect patients' quality of life. Electroencephalography (EEG), which records the brain's electrical activity in real time, plays an important role in epilepsy diagnosis and monitoring.

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.

Screen time was linked to teen anxiety. Then researchers compared twins

A longitudinal study of 21,797 Swedish twins found that heavy interactive screen use during adolescence was associated with more anxiety and depressive symptoms and a higher likelihood of subsequent clinical mental health outcomes. However, these associations weakened substantially when comparing twins with different screen habits, suggesting that shared genetic and environmental factors contribute to the relationship.

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.

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.

Nicotinamide riboside fails to slow progression of early Parkinson’s disease

A major clinical trial involving 410 people with early Parkinson's disease has found no clinical benefit from nicotinamide riboside (NR), a compound that increases cellular levels of nicotinamide adenine dinucleotide (NAD). The findings are published in JAMA.
