Editor's Note: Journalist and crew member Kathryn Eident is traveling on board the RV Atlantis on a monthlong voyage to explore undersea volcanism in the eastern tropical Pacific Ocean, among other research projects. This is the third blog post detailing this voyage of discovery for ScientificAmerican.com
For geologist Tracy Gregg, exploring submarine volcanoes is a lot like being a CSI detective, just without the bodies. While a CSI team gathers evidence to find the killer, Gregg explores the aftermath of a volcanic eruption so she can understand what's happening beneath the Earth's surface. [More]

Truffles Serve Up Environmental Info
Quality truffles can sell for more than a $1,000 a pound. They’re also valuable in environmental research, work that’s discussed in an article called "The Hidden Life of Truffles" in the April issue of Scientific American magazine, by Oregon State University’s James Trappe and Andrew Claridge, visiting fellow at the University of New South Wales in Australia. [See http://bit.ly/9IDzGF ]
Claridge is getting better estimates of Australian endangered species populations, thanks to truffles. Some marsupials are as crazy for truffles as some humans are. Claridge soaked foam pads with olive oil infused with the scent of European black Perigord truffles, and left the pads near motion-sensing cameras. The animals came in droves, with 50 times as many individuals counted as with other techniques. Claridge used the European truffle product because it was easy to get--his team will next see the reaction of native animals to native truffles.

What Is Geoengineering and Why Is It Considered a Climate Change Solution?
When a report on climate change hit the U.S. president's desk, the suggestion was not to cut greenhouse gas emissions.

Bush or even Bill Clinton--it was Lyndon Johnson in 1965. [More]
