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.

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.

A collaborative research study co-led by scientists at the Icahn School of Medicine at Mount Sinai and the Liber Institute for Brain Development has for the first time identified a biological process that may help explain how the brain develops differently in people with Down syndrome.

Vaginal microbiota transplantation without antibiotics fails to restore microbiome balance, yet engraftment suggests avenues for enhancing treatment efficacy.

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

The review indicates nicotine e-cigarettes could surpass traditional quit aids in effectiveness, but lingering safety uncertainties warrant further research.

A study evaluates disinfectants for decontaminating dropped implants in surgery, highlighting risks and the efficacy of CHG and PI in reducing bacterial load.

Scientists at Oregon Health & Science University have uncovered a previously unknown system of internal "trade winds" that help cells rapidly move essential proteins to the front of the cell, reshaping how researchers understand cell migration, cancer spread and wound healing.

Tuberculosis (TB) remains one of the world's most serious public health threats, with approximately one-quarter of the global population infected with Mycobacterium tuberculosis. While most infections remain latent (LTBI), individuals with LTBI are at risk of progressing to active TB and potentially becoming new sources of transmission.

Dentists are exposed to intense lighting for long hours, but its long-term impact on eye health is often overlooked. This study evaluates whether chronic exposure to dental lighting, especially blue and white LEDs, can damage the retina and disrupt its normal function. By combining human data with advanced imaging and animal models, the research uncovers hidden occupational risks and highlights the need for safer lighting practices to help protect dentists' vision.

Artificial intelligence (AI) could help physicians determine if survivors of childhood cancer need extra support - and the more information included in AI prompting, the better its performance. This finding, published today in Communications Medicine by scientists from St. Jude Children's Research Hospital, may guide future integration of AI into clinical workflows.

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.

First systematic review to track long-term trends across pre- and post-pandemic periods finds dramatic rise in screen use among children and adolescents.

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.

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."

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.

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

Some people have a greater genetic risk than others of developing type 2 diabetes. Now, more of these at-risk people are actually developing diabetes than previously.

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.

Boehringer Ingelheim and the Lower Franconian biotech company EMFRET Analytics have signed a cooperation and license agreement for the preclinical development program of the GPVI‑blocking antibody EMA601.
