Metagenomics is so easy to understand, right? Scientists just go out and get DNA sequences from…stuff…in the environment. And then they answer lots of questions, like….um… Yeah sometimes I’m lost too. In metagenomics, researchers collect ocean water or soil samples and sequence random bits of DNA from whatever blob of gunk they collect–they end up . . . → Read More: So you think you know Marine Metagenomics?

The hot, mineral rich water that spews from hydrothermal vents contains a significant amount of fool’s gold, or iron pyrite. Because iron pyrite is more resistant to rusting than basic iron and much of the iron pyrite venting is . . . → Read More: Fool’s Gold from Hydrothermal Vents to Plankton

My thoughts exactly. Let’s break it down. First: X-rays. High-energy waves that help doctors see our bones. Check. Second: fluorescence. Fluorescence is . . . → Read More: Scientist In Residence: Danny Richter on Diatoms and X-ray Whosamagidgets

The experiment involved “fertilising” a 300-square-kilometre (115-sqare-mile) area of ocean inside the core of an eddy — an immense rotating column of water . . . → Read More: Iron Fertilization Will Not Help Global Warming

Blogging, living on reef in a luxury home, getting paid…qualifications needed: charismatic, not needed: advanced degree in marine biology. I can’t believe I wasted all this time on a degree!
