This is SCIENCE FRIDAY. I'm Ira Flatow. We're here in California, broadcasting from the California Academy of Sciences in San Francisco. And just outside the Golden Gate, of course, is the Pacific Ocean. It is the largest body of water on Earth, and its trenches are also the deepest. You could put Mount Everest into some of them, and the top would not even peek out.

A Dutch virologist is considering his full range of legal options if his government refuses to lift the restrictions it has put on his controversial bird flu research, and matters could quickly come to a head after a meeting next Monday that will be attended by U. S. observers.
There's another bit of tragic news to report today: 43 people are dead after a truck crashed into a passenger bus in eastern Mexico today. Authorities told the AFP that the incident happened after a trailer came loose and hit a bus carrying agricultural workers headed to work.

Smoking is bad. Quitting smoking is hard. But exercising can make quitting easier, and make sliding back into smoking less likely.
That's the word from a big new study, which tracked the health and habits of 434,190 people in Taiwan from 1996 to 2008. Smokers who got just 15 minutes of exercise a day were 55 percent more likely to quit than were people who weren't active at all. And those active smokers were 43 percent less likely to relapse when they did quit.
