Nature is relentless, challenging farmers with weeds, insects and diseases. With global food needs skyrocketing as the population and prosperity increase, new techniques are needed to increase yields on smaller farming footprints. GM technology offers real hope if anti-science opposition does not derail it.

Relatively few neurons, only thousands, control appetite in a brain region linked to inhibition, fear and emotion according to a new accidental finding.

A new book by Nicholas Wade is being condemned by scientists, who claim that it paints a false picture of evolutionary genetics and human race. Why has it attracted so much negative criticism?

When does a 7-year-old consider the onset of old age to begin? What about when he�s 70? Ameliorating aging comes with a price: Life extension. We must consider genetic treatments that stop us from aging in light of the fact they might shift our cultural traditions when humans live to 180.

Are you one of the millions of people who enjoy soy milk as an alternative to the dairy variety? Well, if you read Consumer Reports, you might have been startled to read its recommendation to pay much higher prices for non-GMO varieties. What's the science behind this advice. None. It's the latest ride down junk science ally by a once venerable, empirical evidence based magazine.

Do GMO crops "foster monoculture?" Plant pathologist Steve Savage dives into the cropping histories of the Midwest's Corn Belt and finds that corn has been the dominant crop since the 1930s.
Nothing is more challenging to science, or potentially more heartbreaking, than mental illness. The human brain remains inscrutable. But recent advances in GWAS suggest some breakthrough treatments might be on the horizon.
Your brain is making a snap judgement on the trustworthiness of each stranger you see based on their faces -- even when you glimpse them so briefly you don't even remember having seen them. What other complex processing is taking place beneath the level of consciousness?
A study of Mexican genetics reveals staggering diversity. In an increasingly globalized world, with human populations mixing at unprecedented rates, fine-grain genetics studies are going to be more and more important for rewriting clinical guidelines originally based on broad racial categories.
