Closing in on how early life stress changes epigenetic markers
The good news from this mouse study is that if epigenetic stress is recognized, it can be reversed. That means, presumably, that it won’t be passed on: In a study published March 15 in Nature Neuroscience, researchers found that early-life stress in mice induces epigenetic changes in a particular type of neuron, which in turn make the animals more prone to stress later in life. Using a drug that inhibits an enzyme that adds epigenetic marks to histones, they also show that the latent effects of early-life stress can be reversed. “It is a wonderful paper because it is really advancing our ability to understand how events that happen early in life leave enduring signatures in the brain so that Read More ›

Coffee time: How cats court mice
This coffee time is dedicated to: animal mind Urine: Surely not an incentive one would expect, if one must clean litter boxes. But this just in from From BBC News: Cats ‘control mice’ with chemicals in their urine Researchers found that when very young mice were exposed to a chemical in cat urine, they were less likely to avoid the scent of cats later in life. … This new study revealed that baby mice exposed to the compound during a “critical period” in their development would, as adults, react quite differently to their arch enemy’s smell. The team exposed one-month-old mice to the chemical over two weeks. When they were tested later for their reaction, they were much less likely Read More ›
