We Can't Blame Obesity On Our Hunter-Gatherer Ancestors Anymore

One popular idea to explain the current obesity epidemic proposes that our hunter-gatherer ancestors had a fat-storing adaptation, which allowed them to survive frequent famines. Today, with our overabundance of food, this adaptation is causing us to get fat. There's just one problem with this idea — research now shows … » 1/10/14 6:40am 1/10/14 6:40am

Here's why wine snobs should probably be called bacteria snobs

Differences in wine quality between vineyards have long been attributed to processing techniques and seasonal variation.

This is why the ocean is full of dead zones

Every year, a massive "dead zone" develops in the Gulf of Mexico — a region where algae destroys almost all the oxygen in the ocean. No fish or other life forms can survive there. This year's dead zone is roughly 5,840 square miles (see above map). It's almost twice as big as last year's. What causes this watery death… » 8/14/13 5:39pm 8/14/13 5:39pm
