Today in Research: Caffeine Alters Estrogen Levels; Rap in Medicine

Discovered: lube works, caffeine alters estrogen levels, rap meets medicine, and conspiracy theorists don't care about the truth.

  • Caffeine messes with lady hormones. As big coffee consumers, we don't want to believe this bit of research and replace it with everything these studies have told us about all the benefits of caffeine. But that wouldn't be fair to you people who care about health. Looking at women ages 18 to 44, researchers found the drug changed estrogen levels, lowering them for white women and raising them in Asian and black women. The good news: "for women of reproductive age, drinking coffee will not alter their hormonal function in a clinically significant way," study author Dr. Enrique Schisterman said. Phew.

  • Rap meets medicine. In an epic union of two of the world's greatest fields, science is using rap beats to power machines. It's this nifty little machine that harnesses rap's heavy bass to power pulsations. "The acoustic energy from the music can pass through body tissue, causing the cantilever to vibrate," explained Babak Ziaie. Instead of just using tones, they found hip-hop worked better. "Rap is the best because it contains a lot of low frequency sound, notably the bass," he continues. We agree, rap is the best. [Purdue]
