What happens when more of your exercise is vigorous instead of moderate?

In a large UK Biobank analysis, a higher proportion of vigorous physical activity relative to total activity volume was associated with lower risks of eight major chronic diseases and all-cause mortality, even after accounting for overall activity volume. Device-based data suggested that activity intensity generally offered greater preventive potential than total volume alone across most outcomes.

Study reveals how extracellular matrix stiffness regulates breast cancer metastasis

A study by researchers at the University of California San Diego could make it easier to treat breast cancer by uncovering a new way the body helps prevent its spread.

Treating autonomic dysfunction can relieve symptoms of treatment-resistant depression

Consider a house with the water main half shut. The faucets sputter. The toilet runs all night. The garden wilts. You could call a plumber for the faucet, a landscaper for the garden, a different plumber for the toilet, and every one of them would fix something while fixing nothing.

How the nutrient cysteine controls cancer-fighting power of T cells

A research team from the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health have discovered how the immune system's CD8+ T cells use the nutrient cysteine to control two essential functions that compete for this resource - the immune cell's ability to multiply and its ability to kill cancer cells.

New T cell mechanism could lead to longer-lasting vaccines

Researchers at the University of Wisconsin School of Veterinary Medicine have identified a possible way to make longer lasting vaccines for respiratory viruses like influenza and the coronavirus that causes COVID-19.

Lipid nanoparticles help CAR T cells melt pancreatic cancer barriers

Often diagnosed when surgery is no longer an option, pancreatic cancer is one of the most difficult cancers to treat and has one of the lowest rates of survival among major malignancies.

Testosterone level is not always the key to male wellbeing

The connection between testosterone and well-being is weaker than many people think. Although there are clear health connections, a higher testosterone level is not always the key to well-being, according to a thesis at the University of Gothenburg.

Why one vaccine cannot protect against all E. coli infections

The bacterium E. coli is the most common cause of urinary tract infections and bloodstream infections. But in the search for vaccines, researchers have discovered that the bacteria are more resilient than they had thought.

Impaired lipid transport protein locks stressed cells into cellular limbo

When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer proliferate.

New optogenetic method precisely controls marmoset brain communication pathways

Understanding how the brain works requires more than studying single regions in isolation. The cerebral cortex depends on long-distance connections that link specialized areas into coordinated networks.

Mirror image proteins offer new way to disable Alzheimer's disease

Understanding how proteins interact with their own mirror images enabled a Kobe University research team to design a small mirror protein that disables a causal factor of Alzheimer's disease, amyloid-beta.

Scientists use living muscle to reanimate paralyzed organs

What if a technology could reanimate parts of the body that have lost their connection to the brain - like a bladder that can no longer empty due to a spinal cord injury, or intestines that can't push food forward due to Crohn's disease? What if this technology could also send sensations such as hunger or touch back to the brain?

New genetic ‘roadmap’ advances precision therapy for intrahepatic cholangiocarcinoma

The 1,341-gene signature for intrahepatic cholangiocarcinoma offers a framework for precise diagnosis and tailored therapies, addressing tumor heterogeneity.

How video gaming may shape sleep, diet, and activity across the lifespan

This narrative review found that video gaming can have both benefits and risks for health across the lifespan. It may provide short-term stress relief and social connection, but frequent or prolonged gaming is also associated with sedentary behaviour, poorer sleep, disrupted eating patterns, and lower diet quality, with effects shaped by age, sex, timing, content, and motivation.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

Study proposes genetic basis for autism’s strong sex bias

Autism has a significant and enduring sex bias, with roughly four boys diagnosed for every girl. For many years, experts have believed this disparity arises primarily from diagnostic inequities because much of autism research - and the screening tools that grew out of it - has historically focused on boys, effectively setting a male standard for what autism "looks like."

How do diet, smoking, alcohol, and stress reshape the female microbiome?

This review examines how modifiable lifestyle and environmental factors shape the female vaginal, gut, oral, and skin microbiomes, with diet, alcohol, smoking, obesity, stress, hygiene, physical activity, and sexual behaviours all linked to site-specific microbial shifts. It argues that understanding these patterns could help guide future female-focused prevention and intervention strategies.

Whole genome sequencing improves diagnosis of rare diseases

A collaboration between Karolinska Institutet, Karolinska University Hospital, and SciLifeLab has integrated whole genome sequencing into routine diagnostic investigations for rare diseases at Karolinska University Hospital.

Sleep brain activity offers clues to infant neurological development

Electrical signals from the brain could help identify potential issues in the organ's development, a new study reports.

Retinal organoid study identifies pathways and compounds to protect cone cells

Scientists led by Botond Roska at the Institute of Molecular and Clinical Ophthalmology Basel (IOB) and collaborators have identified genetic pathways and compounds capable of protecting cone photoreceptors from the degeneration that underlies conditions like age-related macular degeneration.
