On the other end of being healthy, it seems that eating lots of cured meats could harm your lungs: nitrogen compounds used in the curing process may be causing oxidative stress, reducing lungs' elasticity. This is an interesting find, but I'm not about to stop eating lunch meats over it.
Finally, researchers have found a gene - DUF1220, whose function is unknown - of which we humans have 212 copies, chimps have 37, and rats have one. This difference in copy number may have to do with how and why our brains develop differently than the other animals' do...and perhaps shed light on how we became human. Very cool.
