Optic nerve stimulation to aid the blind

Scientists from EPFL in Switzerland and Scuola Superiore Sant'Anna in Italy are developing technology for the blind that bypasses the eyeball entirely and sends messages to the brain. They do this by stimulating the optic nerve with a new type... Continue Reading →

Gut-brain connection helps explain how overeating leads to obesity

Eating extra servings typically shows up on the scale later, but how this happens has not been clear. A new study published in the Journal of Clinical Investigation by a multi-institutional team led by researchers at Baylor College of Medicine reveals a... Continue Reading →

Tissue model reveals role of blood-brain barrier in Alzheimer’s

Beta-amyloid plaques, the protein aggregates that form in the brains of Alzheimer's patients, disrupt many brain functions and can kill neurons. They can also damage the blood-brain barrier -- the normally tight border that prevents harmful molecules in the bloodstream... Continue Reading →

An alternate theory for what causes Alzheimer’s disease

Alzheimer's disease, the most common cause of dementia among the elderly, is characterized by plaques and tangles in the brain, with most efforts at finding a cure focused on these abnormal structures. But a University of California, Riverside, research team... Continue Reading →

Flavonoid-rich diet protects against cancer and heart disease, study finds

Consuming flavonoid-rich items such as apples and tea protects against cancer and heart disease, particularly for smokers and heavy drinkers, according to new research from Edith Cowan University (ECU). Researchers from ECU's School of Medical and Health Sciences analysed data... Continue Reading →

Allergy, Asthma Risk Are Increased by Microbial Compound in Infant Gut

A study of newborn infants has identified a compound produced by gut bacteria that appears to predispose certain infants to allergies and asthma later in life. “We have discovered a specific bacterial lipid in the neonatal gut that promotes immune dysfunction... Continue Reading →

Scientists can now manipulate brain cells using smartphone

A team of scientists in Korea and the United States have invented a device that can control neural circuits using a tiny brain implant controlled by a smartphone. Researchers, publishing in Nature Biomedical Engineering, believe the device can speed up efforts... Continue Reading →

Widespread aspirin use despite few benefits, high risks

Medical consensus once supported daily use of low dose aspirin to prevent heart attack and stroke in people at increased risk for cardiovascular disease (CVD). But in 2018, three major clinical trials cast doubt on that conventional wisdom, finding few... Continue Reading →

New cell discovered that can heal hearts

University of Calgary researchers are the first to discover a previously unidentified cell population in the pericardial fluid found inside the sac around the heart. The discovery could lead to new treatments for patients with injured hearts. The study led... Continue Reading →
