Sleep duration and genetics interact to affect functional health

Lifestyle-behavioral factors and socioeconomic status play an important role in shaping healthy aging, but their effects may differ depending on your DNA, according to a new international study led by Adelaide University researchers.

Study reveals molecular control of tooth root formation and growth

Tooth root development relies on precise coordination of cellular signals, yet the underlying mechanisms remain unclear. Researchers have uncovered how two proteins, Gli2 and Gli3, work together to control signaling and differentiation in dental progenitor cells.

Blood test may detect cognitive decline years before symptoms

A blood test could help identify people at higher risk of cognitive decline years before a traditional diagnosis is possible – according to University of East Anglia research.

Polygenic embryo testing raises ethical concerns beyond disease prevention

For more than four decades, in vitro fertilization (IVF) has helped families have children. Scientists estimate that more than 10 million people worldwide have been born through IVF and related assisted reproductive technologies, according to the International Committee for Monitoring Assisted Reproductive Technologies.

Aging reshapes breast tissue creating environment favorable for cancer

Scientists have created the most detailed map to date, comprised of over 3 million cells, showing how breast tissue changes as women age – including dramatic changes during menopause.

Gut bacteria determine fiber benefits in celiac disease patients

Many people with celiac disease are advised to eat more fiber to support digestion and manage symptoms, either through diet or prescribed fiber supplements.

Loving-kindness meditation links to lower anxiety through self-compassion

A new study suggests that loving-kindness and compassion meditation may be linked to lower anxiety over time, not just through longer practice, but also by building self-compassion and loosening the grip of distressing thoughts.

How could bisphenol A raise depression risk? Study identifies six key molecular targets

An integrative Translational Psychiatry study linked BPA exposure to major depressive disorder by identifying 571 shared targets and six core genes, with genetic, transcriptomic, docking, and mouse-model data supporting plausible mechanistic pathways. The strongest signals pointed to AKT1, SRC, PLCG2, and JAK3 as potential contributors, while EGFR appeared protective.

How vitamin D in the first 1,000 days may shape lifelong health

This narrative review argues that vitamin D is clearly important for skeletal health during the first 1,000 days of life and may also shape immune, metabolic, and selected neurodevelopmental pathways during early development. However, the authors stress that human evidence for most non-skeletal outcomes remains heterogeneous, with benefits appearing most consistent in populations with baseline deficiency.

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.

New therapy reprograms immune cells to reduce asthma inflammation

A collaborative effort between researchers at the Henan Academy of Innovations in Medical Science, Zhengzhou University, and Shenzhen University School of Medicine has provided the first proof-of-principle study demonstrating that targeting a receptor on the surface of anti-inflammatory regulatory T cells (Tregs) can restore their function and alleviate asthma in mice.

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.

Novel compound clears harmful protein, protects neurons in frontotemporal dementia models

New research from Washington University School of Medicine in St. Louis adds to growing evidence that helping brain cells break down and eliminate their own cellular waste is a promising treatment strategy for a variety of neurodegenerative diseases.

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.
