Mathematical models explain food movement and churning in the digestive tract

Synchronization abounds in nature: from the flashing lights of fireflies to the movement of fish wriggling through the ocean, biological systems are often in rhythmic movement with each other.

Evidence of previously unrecognized hub in the brain's lymphatic drainage system revealed

How does the brain take out its trash? That is the job of the brain's lymphatic drainage system, and efforts to understand how it works have pushed the boundaries of brain-imaging technologies.

Common viruses sharply raise heart attack and stroke risk, major global review shows

In the largest synthesis to date, researchers reviewed 155 studies linking viral infections, including influenza, SARS-CoV-2, HIV, hepatitis C, and shingles, to increased risks of coronary heart disease, stroke, and heart failure. The findings highlight viral infection prevention and vaccination as underappreciated strategies for cardiovascular protection.

First-of-its-kind resource created to identify people with genetic risk for elevated 'bad' cholesterol

An international team led by a University of Pittsburgh School of Medicine scientist has created a first-of-its-kind resource to identify those with a genetic risk for elevated 'bad' cholesterol -- a major contributor to heart disease.

Oligodendrocyte progenitor cells promote blood vessel growth after stroke

Stroke is a leading cause of death and disability, affecting 1 in 4 people during their lifetime. Stroke happens when blood vessels in the brain get clogged or damaged, impairing blood flow and oxygen supply to the brain, which leads to death of neurons and other brain cells.

Intraoperative radiation reduces the recurrence rate of pancreatic cancer

Using targeted radiation during surgery - referred to as intraoperative radiation - to eliminate pancreatic cancer cells that have spread to areas around the pancreas, investigators at Johns Hopkins have been able to reduce the recurrence rate around the pancreas to 5%.

Study links short-term blood pressure variability to Alzheimer's-related brain loss

Even when blood pressure is well controlled, older adults whose blood pressure fluctuates widely from one heartbeat to the next may be at greater risk for brain shrinkage and nerve cell injury, according to a new study led by the USC Leonard Davis School of Gerontology.

Scripps Research professor wins $3.2 million grant to unravel the mysteries of type 1 diabetes

Luc Teyton, professor in the Department of Immunology and Microbiology at Scripps Research, has received a five-year, $3.2 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to help answer how type 1 diabetes manifests and develop potential therapeutics to reverse or prevent the disease.

Two analgesic drugs may one day be repurposed as anti-tumor therapies

Peripheral afferent neurons - nerves that send signals from all areas of the body to the central nervous system (brain and spinal cord) - are known to infiltrate and grow within malignant bone tumors called osteosarcomas, often accompanied by severe pain.

Uncovering mechanisms of neuronal migration in the adult brain

Researchers have discovered how newly created neurons depend on blood flow in the adult brain to travel from their site of origin to their final location.

New imaging technique can map the blood flow of an entire organ in 4D

For the first time, a team of Inserm researchers from the Physics for Medicine Institute (Inserm/ESPCI Paris-PSL/CNRS) has succeeded in mapping the blood flow of an entire organ in animals (heart, kidney and liver) with great precision, in four dimensions: 3D + time.

Subtle brain changes in football players could predict the risk of chronic traumatic encephalopathy

Brain scans from American football players reveal subtle differences in the brain's outer grooves when compared to scans from otherwise healthy men who never played contact or collision sports, a new study shows.

Unlocking the secrets of vascular health through eye imaging

The tiny blood vessels in your eyes might hold the key to predicting a person's risk of developing heart disease and how fast they're biologically aging, according to researchers at McMaster University and Population Health Research Institute (PHRI) - a joint institute of Hamilton Health Sciences and McMaster.

Study shows link between gum disease and white matter hyperintensities

Adults with gum disease may be more likely to have signs of damage to the brain's white matter, called white matter hyperintensities, than people without gum disease, according to a new study published on October 22, 2025, in Neurology Open Access, an official journal of the American Academy of Neurology.
