Targeting the inflamed intestinal wall may be a novel way to prevent inflammation in HIV patients

New UCLA-led research in mice suggests that adding a certain type of tomato concentrate to the diet can reduce the intestinal inflammation that is associated with HIV. Left untreated, intestinal inflammation can accelerate arterial disease, which in turn can lead to heart attack and stroke.

‘Smart’ food packaging material kills microbes and keeps food fresh

A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) and Harvard T.H. Chan School of Public Health, US, has developed a 'smart' food packaging material that is biodegradable, sustainable and kills microbes that are harmful to humans. It could also extend the shelf-life of fresh fruit by two to three days.
