Billy McCarthy lost his mother to suicide when he was a teenager. He cared for his schizophrenic brother as best he could after that, but his brother landed in solitary confinement in prison, where he eventually took his own life, too.

Scientists at the Italian Institute for Nuclear Physics are now touting a successful second experiment that may challenge Albert Einstein's long-held theory of relativity. The results show that neutrinos could travel faster than the speed of light. Guy Raz talks to Brian Greene, professor of physics and mathematics at Columbia University, about the findings.

Melissa Block talks with John Seabrook, staff writer at The New Yorker. His latest article, "Crunch," delves into the world of the SweeTango — a new hybrid apple that is part Honeycrisp, part Zestar. It's sweet and tangy. There's a hint of cinnamon, a hint of pineapple and a whole lot of crunch.

When I was a kid, I assumed that in the future things would get better and better until we were all driving flying cars and playing badminton with space aliens on top of 500-story buildings. Frankly, I kind of counted on this happening. But now I don't assume that we'll just keep going up anymore.
