Whales lost their teeth before evolving hair-like baleen in their mouths

-
Rivaling the evolution of feathers in dinosaurs, one of the most extraordinary transformations in the history of life was the evolution of baleen -- rows of flexible hair-like plates that blue whales, humpbacks and other marine mammals use to filter relatively tiny prey from gulps of ocean water. Now, scientists have discovered an important intermediary link in the evolution of this innovative feeding strategy: an ancient whale that had neither teeth nor baleen. from Latest Science News -- ScienceDaily https://ift.tt/2Rn4LDf

How prions invade the brain

-
The spread of prions to the brain does not occur by direct transmission across the blood-brain barrier, according to a new study. As noted by the authors, insights into how prions enter the brain could lead to the development of effective strategies to prevent neurodegeneration, even after infection outside the nervous system has already taken place. from Latest Science News -- ScienceDaily https://ift.tt/2Ro73C7
