John Hewitt is a neuroscientist who studies the biology of intelligence. He's also a parent. Over the years, Hewitt has periodically drawn upon his scientific knowledge in making parenting decisions.
"I'm a father of four children myself and I never worried too much about the environments that I was providing for my children because I thought, well, it would all work out in the end anyway — aren't the genes especially powerful?" Hewitt says.
Pregnant women hear a lot about things they should avoid: alcohol, tobacco, chemical exposures, stress. All of those have the potential to affect a developing fetus. And now scientists are beginning to understand why.
One important factor, they say, is something called epigenetics, which involves the mechanisms that turn individual genes on and off in a cell.
Bernard Vallius, who heads the group, says it used to be that people ate a sit-down lunch and dinner with family or friends every day. Now people — especially the young and those who live in cities — eat sandwiches or skip lunch altogether and snack, he says.
Sure, Bob Newhart may have won his first Emmy for guest-starring as Professor Proton on the hugely popular show The Big Bang Theory, about four young scientists at Caltech. But behind the scenes is a real-life professor, David Saltzberg of UCLA.
Saltzberg studies high-energy particle physics and high-energy neutrino astronomy, using radio-detection techniques when he's not working as The Big Bang Theory's science consultant.
