Experts have used magnetic resonance imaging (MRI) to better understand the impact a gluten free diet has on people with celiac disease, which could be the first step towards finding new ways of treating the condition. Celiac disease is a chronic condition affecting around one person in every 100 in the general population. When people with celiac disease eat gluten, which is found in pasta and bread, their immune system produces an abnormal reaction that inflames and damages the gut tissue and causes symptoms such as abdominal pain and bloating.

Researchers have revealed a new mechanism underlying how spatial distance between specific regions of DNA is linked to bursts of gene activity. Using advanced cell imaging techniques and computer modeling, the researchers showed that the folding and movement of DNA, as well as the accumulation of certain proteins, changes depending on whether a gene is active or inactive.

Many recent studies assume that elderly people are at particular risk of dying from extreme heat as the planet warms. A new study of mortality in Mexico turns this assumption on its head: it shows that 75% of heat-related deaths are occurring among people under 35 -- a large percentage of them ages 18 to 35, or the very group that one might expect to be most resistant to heat.
