Frailty and immune decline are two main features of old age. Researchers now demonstrate in an animal model that these two age-related impairments can be halted and even partially reversed using a novel cell-based therapeutic approach.

Elderly people are more prone to infectious diseases as the function of their immune system continuously declines w...

Our brains use internet search engine strategies to remember words and memories of past experiences.

In a recent study of epilepsy patients and healthy volunteers, National Institutes of Health researchers found that our brains may withdraw some common words, like “pig,” “tank,” and “door,” much more often than others, including “cat,” “street,” and “stair.” By combining memory tests, brain wave recordings, and surveys of billions of words published in books, news articles and internet encyclopedia pages, the researchers not only showed how our brains may recall words but also memories of our past experiences.

“We found that some wo...

Early findings indicate eating the fruit could help with skin allergies

In a study done with mice and published earlier this month in the journal Nutrients, researchers found that a diet high in black raspberries reduced inflammation from contact hypersensitivity – a condition that causes redness and inflammation in the skin.

“A lot of times, treatments are directly applied to the skin – things like steroids,” said Steve Oghumu, senior author on the paper and an assistant professor of pathology at The Ohio State University.

“And it was interesting that the mere consumption of a fruit can achieve the same effects.”

The researchers put a group of mice on a ...

A new approach in ophthalmology that offers a revolutionary alternative to corneal transplantation has just been developed by researchers and clinicians in North America, Europe, and Oceania. The team was co-led by May Griffith, a researcher at Maisonneuve-Rosemont Hospital Research Centre, which is affiliated with Université de Montréal and is part of the CIUSSS de l’Est-de-l’Île-de-Montréal.

The results of this multinational project have just been published in the journal Science Advances...
