Using a state-of-the-art method, researchers have succeeded for the first time at unraveling the effects of autoimmune antibodies, that are directed against the brain, in detail at the atomic level. To this end, they studied two antibodies that dock to so-called GABA-A receptors in one variant of autoimmune encephalitis. Their findings on the structural mechanisms are an important step towards the development of effective therapies -- and they also pave the way for further promising investigations using the new method.

According to a new study that examined memory in expert birdwatchers, having expert knowledge in a subject helps us memorize new information. This is because, while forgetting often happens when similar memories interfere with each other, expert knowledge provides a mental organizational structure, or scaffolding, that helps us keep new items that we want to learn distinct from each other. This reduces confusion between similar items -- in this case, similar-looking birds.

In a new paper, researchers challenge the longstanding view that the force of natural selection in humans must decline to zero once reproduction is complete. They assert that a long post-reproductive lifespan is not just due to recent advancements in health and medicine. The secret to our success? Our grandparents.
