Satellites are powerful tools. They beam our TV signals, phone calls and data around the planet. They help us spy, they track storms, they power the GPS signals in our cars and on our phones. But they also send back striking, totally disarming images of planet Earth.

What if, before your children were born, you could make sure they had the genes to be taller or smarter? Would that tempt you, or would you find it unnerving?
What if that genetic engineering would save a child from a rare disease?
As advancements in science bring these ideas closer to reality, a group of experts faced off two against two in an Intelligence Squared U.S. debate on the proposition: "Prohibit Genetically Engineered Babies."

For years, I've been hearing stories about the changing agricultural landscape of the northern plains. Grasslands are disappearing, farmers told me. They're being replaced by fields of corn and soybeans.

No single bee (or small band of bees) will stand against the majority, insisting and insisting for hours. They can't.
