Stanford scientists make mouse skin transparent to study brain development

During childhood and adolescence, our brain goes through a lot of changes. But studying those changes in juvenile mice is challenging because scientists don't have a way to repeatedly image the same animal's neural pathways as they grow.

Breathwork may mimic psychedelic effects through brain changes

Breathwork while listening to music may induce a blissful state in practitioners, accompanied by changes in blood flow to emotion-processing brain regions, according to a study published August 27, 2025, in the open-access journal PLOS One by Amy Amla Kartar from the Colasanti Lab in the Department of Clinical Neuroscience at Brighton and Sussex Medical School, U.K., and colleagues.

Chronic neuron overactivation may drive Parkinson's disease progression

Certain brain cells are responsible for coordinating smooth, controlled movements of the body. But when those cells are constantly overactivated for weeks on end, they degenerate and ultimately die.

Gut mast cells produce key molecules driving food allergy anaphylaxis

Food allergies affect more than half a billion people worldwide. In severe cases, even a small bite of the wrong food can trigger anaphylaxis - a rapid, body-wide allergic reaction that can cause difficulty breathing, a dangerous drop in blood pressure and even death.

Longitudinal study reveals how GLP-2 analog therapy transforms the intestinal environment

Researchers from Japan discover that glucagon-like peptide-2 (GLP-2) analogs can deeply and beneficially reshape the intestinal environment.

Multi-analyte test accurately identifies brain cancers using cerebrospinal fluid

A novel, multi-analyte test developed by researchers at the Johns Hopkins Kimmel Cancer Center, its Ludwig Center and the Johns Hopkins Department of Neurosurgery can accurately identify brain cancers using small samples of cerebrospinal fluid (CSF), offering a promising new tool to guide clinical decision-making.

How ‘free from’ and ‘organic’ claims dominate baby food marketing in NZ

A New Zealand study found that all commercial toddler and infant foods carried multiple on-pack claims, often including misleading health, nutrition, or composition messages. Researchers call for tighter regulations to protect caregivers from deceptive marketing.

Food scientists identify worst additives for longevity: flavours, sweeteners, and colourings top list

Researchers analyzing data from 186,744 UK Biobank participants found that ultra-processed food consumption and specific additives, such as sugars, sweeteners, flavorings, and colorings, were linked to higher mortality. Some processing aids showed risks, while gelling agents appeared protective.

Study shows life expectancy slowing across 23 wealthy countries

Researchers forecast that people born between 1939 and 2000 in 23 high-income countries will see slower life expectancy gains than earlier generations. The slowdown stems largely from reduced improvements in childhood survival, with later-life gains unable to offset the decline.
