Surprising: Big Wins Boost Two Types of Memory

featured 56037

Summary: Unexpectedly positive outcomes strengthen memory for specific events. These results may have implications for understanding and treating memory problems associated with depression. Source: Brown University Key finding: Researchers found that moments when outcomes exceed expectations — for example, finding an unexpectedly good parking spot or discovering a $20 bill on the sidewalk — not … Read more

How Mitochondria Shape Immune Responses

featured 23735

Scientists at The Scripps Research Institute (TSRI) have identified a new signaling role for the enzyme RIPK3 in coordinating communication between mitochondria and the immune system. The study reveals that RIPK3 links mitochondrial function to natural killer T (NKT) cell activation, a pathway that influences immune responses to tumors and helps regulate inflammatory processes that … Read more

How Fruit Flies Make Decisions: New Insights from Research

featured 97210

Summary: Researchers compare human habits—like a vinyl collector favoring a particular record store—to a widespread decision-making strategy called operant matching, in which animals distribute choices according to expected rewards. New experiments show fruit flies use the same strategy, and the work pinpoints synaptic mechanisms in the fly brain that implement it. A recent study at … Read more
