Assaf Vardi

Rose Eveleth talks to Assaf Vardi today on the Scientific American Expeditions blog: http://blogs.scientificamerican.com/expeditions/2012/07/11/you-wanted-to-know-who-are-these-scientists-introducing-assaf-vard
One of our scientists, Dr. Assaf Vardi, is off on a month-long cruise. He is on the Knorr, a research vessel operated by the Woods Hole Oceanographic Institute, with a team from the Weizmann Institute and another four research teams on a route that will take them from the Azores to Iceland. On the way, they will be sampling the plankton; among other things they want to understand how the molecular processes that take place in these single-celled organisms affect everything from the ocean's food chain to the oxygen in the atmosphere. Rose Eveleth is posting from the ship daily on the…
Some of the best moments in my job as a Weizmann science writer are the times when a scientist I'm interviewing slips in a finding that shifts my understanding of how the world works. Not long ago, for instance, I was speaking with a researcher about his work on phytoplankton. Now, the fact that phytoplankton release about half of all the free oxygen on the planet should be an eye-opener to anyone, and a reminder of the importance of ocean health. (But that wasn't the surprise.) Dr. Assaf Vardi researches the chemicals that phytoplankton produce to communicate. Of course, all sorts of…
