Mimic molecules to protect against plague

Science – Bacteria that cause pneumonic plague can evade our first-line defences, making it difficult for the body to fight infection. In fact, a signature of the plague is the lack of an inflammatory response.

Brain 'trick' offers treatment hope for Alzheimer's

Science – By studying the chemistry and structure of relevant enzymes, the research teams at York, led by Professor Gideon Davies, and Simon Fraser, led by Professor David Vocadlo, have designed an enzyme inhibitor that prevents the phosphorylation of tau in animal models. They have effectively tricked the brain's own enzymes into installing a sugar on to tau in place of the detrimental phosphates.
