• Novel genetic patterns may make us rethink biology and individuality
    Scientists have made two novel discoveries: 1) a person can have several DNA mutations in parts of their body, with their original DNA in the rest — resulting in several different genotypes in one individual — and 2) some of the same genetic mutations occur in unrelated people. We think of each person’s DNA as unique, but if a person can have more than one genotype, this may have broad implications.
  • New method predicts time from Alzheimer’s onset to nursing home, death
    A research team has clinically validated a new method for predicting time to nursing home residence or death for patients with Alzheimer’s. The method uses data from a single patient visit, and is based on a complex model of Alzheimer’s progression developed by consecutively following two sets of Alzheimer’s patients for 10 years each.
