Sea cucumbers aren't all boring, trundling bags. Some of them swim -- and glow. Though I opted to focus on creatures found at greater depths in my last post, one of the creatures observed by the Deepsea Challenger expedition in the New Britain Trench at a relatively shallow 1000 meters was just such a swimming sea cucumber...

Anglerfish and comedy always seemed like a natural pairing. But it took internet humorist Ze Frank to bring the two together in one delicious dish. The natural history documentary parody series "True Facts About ..." by Frank has become a minor youtube sensation...
Confused by what this might be? So were scientists for several hundred years. Apparently, the occupant of this contorted alder root also likes hanging out on your floor.
Last month, I was lucky enough to be asked by fellow Sci Am blogger Carin Bondar to compose and record a short spot about my first February nematode post (Nematode Roundworms Own This Place) for our new Sci Am feature Best of the Blogs...
It's often said that we know less about the bottom of our own ocean than we do about the surface of Mars. The governments of the world, and our government in particular, seem presently much less than enthusiastic about exploring the oceans of our own planet than in exploring other planets (ocean research seems to have taken a particular hit in the last decade of Congressional budget cuts, although admittedly, all agencies have seen cutbacks)...

Consider this image: Is it a work from a modern-day Book of Kells ? A Chinese seal? The cover of The Neverending Story ? No.Would you have guessed it is from a U.S.
The next time you find yourself becoming mosquito chow, remember this video: This is Strelkovimermis spiculatis -- a parasitic nematode, or roundworm -- casually escaping from an unlucky, soon-to-be-expired mosquito larva...
Mosses, which probably already have an inferiority complex, must feel especially inferior in Sequoia National Park. When you stand in the shadows of giants, how will you ever get noticed?If you are lucky, someone like Lena Coleman will come to your rescue.You may have recently read David Quammen's wonderful profile of The President, the second-largest tree on Earth and a resident of Sequoia National Park...
This curious creature, captured here under the microscope, is not a protist. It's an animal. An animal, in fact, that can be smaller than some unicellular microbes.

Spores of Exserohilum rostratum, stained blue. Notice the brown pigment of the cell walls; this is melanin, the same pigment that darkens human skin.
The primary culprit in the recent flare-up caused by tainted steroids, Exserohilum rostratum, is not an especially picky eater. Although the fungus prefers grasses, it will dine on many items—including humans...
