We’ve all been there: We eat an entire sleeve of fat-free, low-calorie cookies and we’re stuffing ourselves with more food 15 minutes later. One theory to explain this phenomenon is that artificial sweeteners don’t contain the calories or energy that evolution has trained the brain to expect from sweet-tasting foods, so they don’t fool the brain into satisfying hunger. However, until now, nobody understood how organisms distinguish between real sugar and artificial sweetener.
Science has helped us to live longer and in some cases much fuller lives. Unfortunately for some with serious medical conditions, they may lead a long life, but a life of what? To that end a group of researchers set out to help people with hormone deficiencies and the team has developed a potential new therapy based on an unlikely model: immune molecules from cows.
