In December, Ibloggedabout an animal most people have never heard of–the comb jelly. It’s a gorgeous, mysterious creature that just might belong to the oldest lineage of animals alive today. Today, over at National Geographic News, I’m reporting on a new study of the comb jelly that suggests it’s even more interesting than that. Unlike all other animals with a nervous system, it seems to have evolved nerves and a brain all its own. It even has its own special neurochemical language. If true, it’s about as close to an alien intelligence that we can encounter here on Earth.Check it out.

“It’s a paradox,” said Leonid Moroz, a neurobiologist at the University of Florida in Gainesville and lead author of a paper in today’s Nature about the biology of the comb jelly nervous system. “These are animals with a complex nervous system, but they basically use a completely different chemical language” from every other animal. “You have to explain it one way or another.”

The way Moroz explains it is with an evolutionary scenario—one that’s at odds with traditional accounts of animal evolution.

I’ve taught writing semi-regularly over the past few years. Over that time, I’ve come to realize that one of the biggest challenges in learning how to write about the natural world is to learn how to skillfully wield beautiful, plain language . Scientists and scientists-in-training often lard their writing with jargon, rather than looking for a conversational equivalent. This addiction to jargon can leave a piece of writing sterile. It can mystify everyone except the experts–which is a bad strategy if you aspire to write for the public. An addiction to jargon can even create catastrophic misunderstandings. Readers may apply a non-technical definition for a word that a scientist uses with a very technical meaning in mind. (Think of “theory” as a hunch.)

When Predators Vanish, So Does the Ecosystem

Mark D. Bertness, an ecologist at Brown University, began studying the salt marshes of New England in 1981. Twenty-six years later, in 2007, he started to watch them die. In one marsh after another, lush stretches of cordgrass disappeared, replaced by bare ground. The die-offs were wiping out salt marshes in just a few years.

“It’s unbelievable how quickly it’s moved in,” Dr. Bertness said.

Scientists have been witnessing a similar transformation in a number of plant species along coastlines in the United States and in other countries. And in many cases, it’s been hard to pinpoint the cause of the die-off, with fungal outbreaks, pollution, choking sediments stirred up by boats, and rising sea levels proposed as killers.
