New York Times science reporter Gina Kolata explains the study and how it might affect your next doctor's visit. To find out more, read Gina Kolata's article, "Colonoscopies Miss Many Cancers, Study Finds," at the New York Times.

Tuesday, November 25, 2008

Now that it's possible to program unmanned combat vehicles to make decisions about where (and who) to strike in war situations, new questions of ethics have risen: In which situations can we allow robots to make their own decisions? Can we program robots to follow the Geneva Conventions? There is a more basic question, too: Do we even want robot soldiers?
"The question of under what circumstances is it ethical to fire a lethal weapon — whether it's possible to build that capacity into a robot."
— Cornelia Dean on the ethics of programming robots for war

Blame evolution for our urge to skewer Wall Street

Tuesday, October 07, 2008

How many times have you heard the phrase, “Life’s not fair?” And yet, we haven’t let it stop us from trying to make everyone equal. We right wrongs, punish evil-doers, stop injustice. But what explains our urge to retaliate or our need to stick it to Wall Street for the subprime mess? It turns out it’s all in our genes, baby. New York Times science reporter Benedict Carey talks about the evolution behind retaliation, and our primal urge to make the world a little fairer.
