For years, ripples at the surface of the Dead Sea hinted there was something mysterious going on beneath its salt-laden waters. But in a lake where accidentally swallowing the water while diving could lead to near-instant asphyxiation, no one was in a hurry to find out what it might be.This year, some intrepid divers changed that, stumbling onto a geological and biological treasure and capturing it on video.

When I took botany and taxonomy of vascular plants in college, we spent many an hour poring over specimens under dissecting microscopes pulled with tweezers from smelly jars of preserving liquid.

There is something curious about the sedimentary rocks laid down around the world 250 million years ago, at the height of Earth's greatest extinction: they are often riddled with filaments, and no one is sure what they are.
Today my Q and A was posted in the continuing series of new blogger profiles here at Sci Am. Go check it out!As well, I was captured on film (although my last name was not quite captured in writing) in this story about mushroom hunting in Colorado in the New York Times .

When you read a story, you may occasionally wonder what the reporter went through to get it. About a month ago I arose at 5 a.m. to accompany two wildlife biologists and three fisheries volunteers into the high country of Colorado in order to report a story that came out in High Country News this past week.Over the course of a 12-hour day, we covered about 10 miles, climbed several thousand feet, slogged through bogs in which I sank to my calves, swatted clouds of mosquitoes, and were drenched by rain in order to get to the high ponds and puddles where boreal toads breed.
