Cognitive decline and dementia already affect more than 55 million people worldwide. This number is projected to skyrocket over the next few decades as the global population ages.

There are certain risk factors of cognitive decline and dementia that we cannot change – such as having a genetic predisposition to these conditions. But other risk factors we may have more power over – with research showing certain modifiable lifestyle habits, such as smoking, obesity and lack of exercise, are all linked to higher risk of dementia.

What role nutrition plays in preventing cognitive decline and dementia has also been the focus of scientific research for ...

A team of materials scientists and engineers from Donghua University, in China, and the National University of Singapore, has developed a type of fiber that does not rely on chips or batteries to convert visual signals to digital transmissions as it interacts with the human body.

The paper is published in the journal Science. Yunzhu Li and Yiyue Luo with the University of Illinois Urbana-Champaign and MIT, respectively, have published a Perspective piece in the same journal issue outlining the work done by the team on this new effort.

Over the past several years, scientists have been trying to find a way to in...

Scientists at King’s College London have discovered a new cause for asthma that sparks hope for treatment that could prevent the life-threatening disease.

Most current asthma treatments stem from the idea that it is an inflammatory disease. Yet, the life-threatening feature of asthma is the attack or the constriction of airways, making breathing difficult. The new study, published in Science, shows for the first time that many features of an asthma attack—inflammation, mucus secretion, and damage to the airway barrier that prevents infections—result from this mechanical constriction in a mouse model.

The findings suggest that blocking a process that normally causes epithelial cell death could prevent the damage, inflammation, and mucus that result from an asthma attack.

One of the reasons is that it increases your pain tolerance. Researchers found that people who were more active in their free time had a lower chance of having various types of chronic pain 7-8 years later. For example, being just a little more active, such as going from light to moderate activity, was associated with a 5% lower risk of reporting some form of chronic pain later...
