Implantable islet cells could control diabetes without insulin injections
The cells can survive in the body for at least three months, producing enough insulin to control blood sugar levels, research shows.
Study reveals why some cancer therapies don’t work for all patients
A backup survival pathway can help tumor cells resist certain lung cancer and other drugs. Combining therapies may offer a solution.
Three anesthesia drugs all have the same effect in the brain, MIT researchers find
Discovering this common mechanism could lead to a universal anesthesia-delivery system to monitor patients more effectively.
Scientists discover genetics behind leaky brain blood vessels in Rett syndrome
By showing the problem derives from genetic mutations that lead to overexpression of a microRNA, MIT researchers’ study points to potential treatment.
How the brain handles the “cocktail party problem”
Using a computational model, neuroscientists showed how the brain can selectively focus attention on one voice among others in a noisy environment.
Injectable “satellite livers” could offer an alternative to liver transplantation
The engineered tissue grafts could take on the liver’s function and help thousands of people with liver failure.
AI to help researchers see the bigger picture in cell biology
By providing holistic information on a cell, an AI-driven method could help scientists better understand disease mechanisms and plan experiments.
Fragile X study uncovers brain wave biomarker bridging humans and mice
Researchers find mice modeling the autism spectrum disorder fragile X syndrome exhibit the same pattern of differences in low-frequency waves as humans — a new marker for treatment studies.
AI algorithm enables tracking of vital white matter pathways
Opening a new window on the brainstem, a new tool reliably and finely resolves distinct nerve bundles in live diffusion MRI scans, revealing signs of injury or disease.
New vaccine platform promotes rare protective B cells
Based on a virus-like particle built with a DNA scaffold, the approach could generate broadly neutralizing antibody responses against HIV or influenza.
New tissue models could help researchers develop drugs for liver disease
Two models more accurately replicate the physiology of the liver, offering a new way to test treatments for fat buildup.
How a unique class of neurons may set the table for brain development
Somatostatin-expressing neurons follow a unique trajectory when forming connections in the visual cortex that may help establish the conditions needed for sensory experience to refine circuits.
Chemists determine the structure of the fuzzy coat that surrounds Tau proteins
Learning more about this structure could help scientists find ways to block Tau from forming tangles in the brain of Alzheimer’s patients.
A protein found in the GI tract can neutralize many bacteria
The protein, known as intelectin-2, also helps to strengthen the mucus barrier lining the digestive tract.
Study: High-fat diets make liver cells more likely to become cancerous
New research suggests liver cells exposed to too much fat revert to an immature state that is more susceptible to cancer-causing mutations.
