Swedish researchers use 3D model to study snoring mechanics

Anyone who has had to share a room - or worse, a bed - with a loud snorer knows the effect unchecked snoring can have on sleep, sanity, and emotional stability.

What a 38-year study suggests about red meat, white meat, and mortality

Lower intake of red and processed meat was associated with small reductions in all-cause, heart disease, cancer, and stroke mortality in a cohort of nearly one million US adults followed for decades. White-meat-only diets showed additional benefits in some subgroups, while vegetarian diets produced few consistent associations and were limited by small participant numbers and a single baseline dietary assessment.

What 720,000 adults reveal about artificial sweeteners and diabetes risk

A meta-analysis of six prospective cohort studies involving 721,003 adults found that higher artificial sweetener intake was associated with a 31% greater risk of developing type 2 diabetes. The evidence was rated low certainty because of substantial heterogeneity, observational study designs, and potential residual confounding, meaning the findings do not establish causation.

A 30-year study found a surprising link between alcohol, survival and heart attack risk

In a 30-year study of 973 middle-aged Swedish male automotive workers, alcohol consumption was associated with lower all-cause mortality and longer estimated time to death, while beer consumption was linked to a higher likelihood of myocardial infarction. No significant association was found between alcohol consumption and stroke, and the authors cautioned that socioeconomic differences, self-reported intake, and other unmeasured factors may have influenced the findings.

Superstorm Sandy reshaped indoor fungal communities, with an unexpected asthma result

and lower fungal diversity than non-damaged homes. Despite these persistent but variable fungal changes, researchers found no statistically significant increase in asthma morbidity, impaired lung function, or airway inflammation among children with relatively mild asthma.

A study of 60 popular Chinese teas found reassuring results and one important warning

Researchers analyzing 60 best-selling online teas in China found that concentrations of six harmful elements remained within Chinese national limits and modeled noncarcinogenic risks were below concern thresholds.

Social media isn’t simply good or bad for young people, and this review shows why

Social media can support connection, self-expression, help-seeking, and community among adolescents and young adults, but problematic use is associated with depression, anxiety, loneliness, poor sleep, and body image concerns. The review finds that mental health effects depend less on screen time alone than on how social media is used, what content people encounter, and their individual, developmental, and cultural context.

AI took on doctors in simulated video consultations, and the results were striking

Google researchers developed AMIE, a Gemini-based multi-agent system combining real-time audio-visual perception, clinical reasoning, and low-latency dialogue for simulated video consultations. In a randomized OSCE across 100 clinical scenarios, AMIE Video matched or exceeded primary care physicians across core clinical measures, while patient actors preferred video over text, although real-world clinical validation is still needed.

Inhaled cannabis reduces premature heartbeats in habitual users

Habitual cannabis users experienced about 9% fewer premature heartbeats on days they inhaled cannabis compared with days they abstained, a counterintuitive finding that adds to the complex and evolving understanding of how cannabis affects the heart, new UC San Francisco-led research found.

High frequency brain waves help coordinate human working memory

Research from scientists at University of California San Diego School of Medicine and collaborators has shed new light on how the human brain coordinates working memory, the process in which the brain encodes information for immediate or short-term use.

Targeting single gene reverses developmental deficits in adult mice

Some of the symptoms of neurodevelopmental disorders (NDDs) such as autism spectrum disorder and epilepsy may result from dysfunction of certain neurons in the brain and their ability to change their properties in response to experiences-a process called experience-dependent plasticity.

Laboratory chemical exposure and poor diet increase odds of health symptoms in young scientists

Young scientists who frequently handle laboratory chemicals and consume relatively few antioxidant-rich foods may be more likely to report symptoms such as fatigue, headaches, pallor, and easy bruising, according to a new study of university students in Nigeria.

Healthy lifestyle cuts hearing impairment risk by 14%, metabolism is key driver

Hearing impairment ranks as the third largest contributor to global disability among sensory disorders, with prevalence rising across younger and middle-aged populations alongside older adults.

Microcurrent stimulation shows immediate reduction in surgical scar depth

A newly accepted pilot study in the Journal of Bodywork & Movement Therapies reports that direct-current (DC) microcurrent stimulation was associated with a statistically significant reduction in measured postsurgical scar depth immediately following a single treatment.

Nocturnal micro-awakenings linked to genetic risk of Alzheimer's disease

What if certain signs of the disease were to manifest themselves subtly during sleep, long before the first memory problems appear? This is the line of inquiry being explored by a team of researchers at ULiège, with the support of the Stop Alzheimer's Foundation.

One cognitive ability stood out in a study of Western diets and Alzheimer’s risk genes

A Western dietary pattern was associated with faster attention decline among older adults carrying the APOE ε4 allele, while no significant cognitive associations emerged for a Prudent dietary pattern. However, the Western diet association lost statistical significance after excluding participants with possible baseline cognitive impairment, making the finding exploratory.

What 38,000 trauma and incident records reveal about e-scooter safety

E-scooter riders admitted with moderate-to-severe trauma showed a distinct injury profile, with proportionally more traumatic brain, vascular, and internal organ injuries than motorcyclists and fewer fractures. Rental-scooter data also linked greater reported injury severity with younger age and female sex, while collision rates varied with area-level deprivation.

H5N1 infections remain rare among workers exposed to infected birds

A two-year cohort study of 428 people exposed to H5N1-infected birds in England found fewer than 1% met criteria for infection, with no severe disease or secondary human transmission. The findings support continued PPE use, biosecurity, and targeted surveillance while highlighting challenges around occupational exposure, mucosal contamination, and pandemic preparedness.

Study reveals how wind helps animals track hidden odors

Humans trust dogs to help find missing people and bees to pollinate their crops. But scientists still don't fully understand how these animals use their extraordinary sense of smell to locate the source of an odor.
