Nuclear fallout used to spot fake art

Art & Design – Scientists and art historians have developed what they say is a foolproof way of identifying forged works of art. They can distinguish between art created before 1945 and that produced after that date by measuring levels of the isotopes caesium--137 and strontium--90. These isotopes do not occur naturally but are released into the environment by nuclear blasts.

In fact, a signature of the plague is the lack of an inflammatory response. Now, scientists have discovered a way to protect against death following infection with plague bacteria, by using molecules that can mimic the pathogens.

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.
