Uc Science Today

Hey there! This week on Science Today, we learned how the sense of smell impacts our metabolism. According to Andrew Dillin, a molecular biologist at UC Berkeley, if there is a lack of smell the body is wired to burn all the food that comes in. It doesn’t store any of it. And Dillin discovered that lab animals lacking a sense of smell remained thin even after gorging on fatty food. “There is something about the wiring of the sensory system of smell into the brain to control the rest of the body’s metabolism." But before you think you’ve found the perfect diet, Dillin says scientists still don’t know exactly how the sensory organs for smell are integrated with the brain. That requires more research in the lab – and then there will be more work looking into if the mice research translates to humans. While on campus, we visited psychologist Robert Levenson, who told us that when it comes to looking after loved ones with dementia, caregivers really need to give it their all. “If you are not able to bring your
