There's a lot of "Can X make you gay?" articles being written these days. This fellow says soy is making you gay and even the New York Times wonders if you have a gay car.

Now a study from the University of Pittsburgh says that fish from Pittsburgh rivers contain substances that act like estrogen.

Estrogen. The female hormone.

Anyone can tell you, the surest test of your science chops is your ability to make a kid understand it. Science, at its most fundamental, can be understood by anyone if explained properly. Science is, for the most part, conceptual. The math is relatively unimportant as long as you understand why things work the way they work.

The first fax machine had no value. It couldn't send a fax to anyone. It was, from a value perspective, useless.

The second fax machine added value to the first because it now had something which could receive faxes. The third added value to the first two and received value from them in the network as well. As each fax machine came into existence, the value it added was nonlinear. The more fax machines that existed, the more value each of them had.

Many things in life are like that.

For all that Darwin did, Evolution as yet has no explanation for puzzling animal behavior.

Social insects provide some of the most fascinating examples of altruism in the natural world, with sterile workers sacrificing their own reproduction for the greater good of the colony.

That isn't the case with all insects - in some cases, there is a very real battle of the sexes going on, even in their larvae.

It's been generally believed that sterile 'soldier' larvae act in positive ways, by protecting them from attack by other species of parasitoids.

Velociraptor attack is the 3rd leading cause of death for men age 27-29. However, everyone must think about the implications of velociraptors: young and old, men, women and transgendered persons.

The American Society for Velociraptor Attack Prevention is a bi-partisan group of professionals, dedicated to the diffusion of knowledge concerning velociraptor attack prevention.

You may have read about the strange double asteroids dancing in space but putting together the pictures is a perfect example of science collaboration.

Prior to 2000, Antiope was just another asteroid. Then the 10-meter Keck II telescope in Hawaii discovered it was a doublet but not much else was known.

Two years ago, improved images from the European Southern Observatory's 8-meter Very Large Telescope (VLT) in Chile and Keck II determined an approximate orbit of the asteroids - but information was still sparse.
