Tree parasite falling victim to another interloper
Parasitic wasps that invade sand live oak trees in southern Florida are finding themselves the victims of another parasite -- the love vine, according to a study published in Current Biology. The love vines take over galls created by the wasps to take advantage of the trees, often killing the wasps by depriving them of nutrients.

Break the cycle of poor sleep, unhealthy diet
Research shows that not only does poor sleep affect food choices, but food choices also affect sleep quality, and a diet rich in tryptophan, B vitamins and magnesium encourages melatonin production and secretion, promoting quality sleep, writes clinical dietitian Sophie Medlin, who teaches nutrition and dietetics at King's College London. Dairy products, nuts and lean meats are good sources of all three nutrients; and fish, pulses, beans and lentils provide at least two of the three, Medlin writes.

AI algorithm may foretell Alzheimer's odds 5 years in advance
Canadian researchers found that an artificial intelligence algorithm based on blood tests and other clinical data in the Alzheimer's Disease Neuroimaging Initiative can forecast the risk of Alzheimer's five years before the appearance of major symptoms. The approach, described in PLOS Computational Biology, could help physicians better treat individuals at risk for Alzheimer's disease, said researcher Mallar Chakravarty.

Cystinosis study receives $1.54M funding boost
Genome Quebec and Genome Canada awarded a $1.54 million grant to McGill University Health Centre in Montreal to develop a treatment for cystinosis, a rare kidney disease.
