Predictably, things have gotten worse since then. Robert Diaz, an ecologist at the College of William and Mary in Virginia who helped UNEP with its numbers, reports in the current issue of the journal Science that today there are more than 400 known dead zones along coastlines around the world, covering roughly 95,000 sq. mi. of seabed. Some of the dead zones that Diaz and his Swedish co-author identify in their review have been around for some time, but have only recently been studied. Many others appear to be new. About 8% of them, mainly those...
...sauvignon. But an electronic "tongue" recently unveiled by scientists at Barcelona's Institute for Microelectronics is capable of identifying different wines and may be used as a new weapon in the battle against wine fraud. In a study published last week in the Royal Society of Chemistry's journal the Analyst, Cecilia Jonquera-Jiménez and her colleagues announced that by using microsensors cued to chemical ions, their device, or "e-tongue," can distinguish among grapes and vintages...

The well-known authors of the paper included surgeons who have spent their careers doing the operation.

One of doctors' most convenient sources of new-drug information is, therefore, also the most biased: the chipper, gift-laden pharmaceutical salespeople who come to doctors' offices bearing free samples, prescribing tips and copies of the latest study that shows how great their...
