Inulin, a type of fiber found in certain plant-based foods and fiber supplements, causes inflammation in the gut and exacerbates inflammatory bowel disease in a preclinical model, according to a new study by Weill Cornell Medicine investigators. The surprising findings could pave the way for therapeutic diets that may help ease symptoms and promote gut health.

The study, published March 20 in the Journal of Experimental Medicine, shows that inulin, which is found in foods such as garlic, leeks and sunchoke, as well as commonly used fiber supplements and foods with added fiber, stimulates microbes in the gut to release bile acids that increase the...

Theoretical physicists at Utrecht University, together with experimental physicists at Sogang University in South Korea, have succeeded in building an artificial synapse. This synapse works with water and salt and provides the first evidence that a system using the same medium as our brains can process complex information.

The results appear in the journal Proceedings of the National Academy of Sciences.

In the pursuit of enhancing the energy efficiency of conventional computers, scientists have long turned to the human brain for inspiration. They aim to emulate its extraordinary capacity in various ways.

These efforts hav...

A brief episode of anger triggered by remembering past experiences may negatively impact the blood vessels’ ability to relax, which is essential for proper blood flow, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Previous research has found that impairment of blood vessels’ ability to relax may increase the risk of developing atherosclerosis, which may, in turn, increase the risk of heart disease and stroke.

“Impaired vascular functi...
