This Week’s Headlines: Running May Reduce Knee Inflammation, Honeybees Aid Memory Study, Research Shows Healthy Relationships Bring More Joy Than Money

Running may decrease knee inflammation. Even if you look like Phoebe from friends while you’re doing it, running is one of the best workouts for your heart. Unfortunately, running can also be detrimental to your knees, which take a pounding with every step, but new research shows that moderate running may actually be beneficial to your knees. Researchers out of Brigham Young University tested the knee joint fluid of healthy adults before and after running. They found that 30 minutes of moderate running actually decreased knee inflammation, the hallmark of osteoarthritis. While this doesn’t necessarily mean runners are less likely to develop bone problems in their knees, it does suggest that running safely and in moderate amounts may provide newfound benefits to knee health. Wondering what else to look out for when running? Here are the most common injuries. (BYU)

Honeybees help uncover molecular mechanisms for memory. Who could forget the classic movie masterpiece Bee Movie? New research suggests that the bees still remember! In a recent study out of Frontiers in Molecular Neuroscience, researchers examined how bees are able to maintain complex memories like where all that tasty pollen is—the secret may lie in DNA and a process called “methylation.” Methylation is one way that our bodies can turn genes on and off without altering the structure. When scientists stopped the bees’ ability to methylate DNA, the bees had difficulty building new memories. But increasing their ability to methylate DNA caused an increase in their ability to make new memories. While this finding may not translate to humans just yet, it does provide insight into the memory process and could help researchers studying cognitive disorders like Alzheimer’s disease.

Study says healthy relationships increase joy more than money. In a study conducted by the London School of Economics, 200,000 around the globe were asked to link various life events to their level of happiness (ranging from 1 to 10). They found that employment was linked to happiness, but that a doubled salary or any other large financial increase was not reflected accordingly on the happiness scale. As it turns out, having a healthy and functional relationship seemed to be correlated to increased joy, above all other factors. This just goes to show: It’s not all about the Benjamins, after all. Here are five simple steps to happiness that you can try out. (GUARDIAN)
