Robert Siegel talks to retired Navy Captain Don Walsh about the attempt by movie director James Cameron to take a submersible capsule to the bottom of the Mariana Trench — the deepest spot on Earth. Walsh says the National Geographic and James Cameron expedition will be a combination of science and adventure, because Cameron is a storyteller and dedicated amateur explorer. Walsh made a 1960 dive to the same trench.

Reporting in Cell Metabolism, researchers write that when people who lead relatively sedentary lives worked out the DNA in their muscle fibers changed almost immediately. Scientists also found caffeine had the same effect on isolated rodent muscles. Study co-author Juleen Zierath discusses the DNA modifications.

The huge solar storm that NASA detected hurtling toward Earth hit our planet at 5:42 a.m. ET Thursday. So far, there have been no reports of major power or communications disruptions. But it’s not the last you’ll hear about solar storms; the sun’s activity won’t peak until 2013.
The sun ejected two huge solar flares Tuesday, and NASA says that we here on Earth will likely be affected somewhat by the magnetic fields and ionized gas that are now shooting toward the planet. But the phenomena might also bring aurora light shows to residents of the northern United States
