Three decades ago researchers discovered what are essentially enormous saltwater lakes in the Atlantic Ocean. These “lakes,” called meddies, are gently spinning lenses of water up to 100 kilometers across and one kilometer thick. They float a few hundred meters below the surface of the ocean. Such large, warm bodies, which turned out to come from the Mediterranean Sea, should have an impact on heat exchange in the ocean—and on the planet’s climate. But efforts to study meddies—conventionally by dropping probes that directly measure the ocean’s temperature, salinity and velocity—have proved too costly, infrequent and spread out to reveal how the meddies dissipate their heat.

If At First You Don’t Succeed, Cool Off, Revise, and Submit Again
The sting of rejection was just as sharp the fourth time around for Marcus Bischoff, a postdoc at the Laboratory of Molecular Biology at the University of Cambridge , U.K. “There’s a lot of disappointment,” he says, when your manuscript gets rejected by a journal. After a year of trying, he was both relieved and pleased when the fifth journal–a “good journal,” he says–accepted his paper.

Geoscientists in High Demand in the Oil Industry
Six years ago, would-be lawyer Kira Diaz-Tushman heard a National Public Radio program about the impending retirement of senior U.S. Geological Survey (USGS) geologists. “I thought, ‘That sounds fun. I want to do what they’re doing and play around in the field.’ ” So she double-majored in geology and political science at Bryn Mawr College in Pennsylvania and did a summer internship at USGS.

The brain looks forward
The brain takes nearly one tenth of a second to consciously register a scene. But the scenery changes far more quickly than that when we move. How does our brain cope? By constantly predicting the future, posits Mark Changizi, now at Rensselaer Polytechnic University.
