An Indian zoologist said Monday he has found a new species of limbless lizard in a forested area in the country's east. "Preliminary scientific study reveals that the lizard belongs to the genus Sepsophis," said Sushil Kumar Dutta, who led a team of researchers from "Vasundhra," a non-governmental organization, and the North Orissa University.

By The News Tribune, Tacoma, Wash.  Jun. 15--Endangered wild fish are not the same as hatchery fish. That's because hatchery fish are neither wild nor endangered. Any policy that treats them the same hardly honors the Endangered Species Act.

For American parents looking for donor sperm to produce blond, blue-eyed Scandinavian babies, the search just got a little trickier. A ban on sperm from all European countries with exposure to mad cow disease means U.S. sperm banks are running low.

Researchers have new evidence that as the density of salmon farms increases, they can drive nearby wild salmon runs to extinction. The problem is sea lice, a natural parasite that normally attaches to adult salmon with little ill effect and has little contact with vulnerable juvenile salmon. All that changes, however, when fish farms move in.

By Kathirasen  THERE'S something fishy going on in rivers and seas.  An increasing number of male fish are changing sex midway to become female. And they don't have to pay exorbitant sums of money to some surgeon somewhere to do it either.

A large study has found that children of women who ate little fish during pregnancy had lower IQs and more behavioral and social problems than youngsters whose mothers ate plenty of seafood, a finding that challenges the U.S. government's standard advice to limit seafood while pregnant.

One of my buddies had a brilliant idea I hadn't thought of: Check Pennsylvania's maps for what's called a co-op farm. It's not a commune, it's a farm which offers up it's land to the public for hunting.  What the Farmer Gets  If the hunters are decent-folk, they generally clean up the trash off the property. I personally built a blind out of rocks I happened to find in a fallow field to give me something to sit on and a hiding place. The blind is next to a power utility pole, so it gives me a great shot at birds coming in slowly to land on the wires. He got his field cleaned essentially for free since I also picked up trash. I don't want my game animals eating garbage.  The other bonus the farmer enjoys is limited crop losses to wildlife. This particular farmer was doing the soy-corn-fallow crop rotation which is pretty typical Pennsylvania crop rotation. Doves love this stuff and eat it up. Probably about 2/3rds of the doves I cleaned had corn in their crop.  What the Hunters Get  A place to hunt with a ton of acreage devoted to what essentially amounts to bait.

How many genes does it take to make a human? Only about the same number it takes for a small flowering plant or a tiny worm, says a new estimate that&#39;s sharply reduced from just three years ago.
