It's been a fairly slow news week in science, but there are still a few fascinating stories to share with you. Researchers have made a potential breakthrough in fetal genetic testing, dinosaurs may not have been as big as we thought, and some birds have different personalities according to their coloring. Oh, and penguins are scandalously filthy sexual deviants. Yeah, I figured that would get your attention!

From the article:

Several interesting new scientific studies have been released in the last two weeks. Standards for science education in the United States have been examined and were largely found to be woefully inadequate, the mother of modern racehorses has been found, and the biggest mammal on earth shows no sign of stopping its growth. In addition, Russian researchers in Antarctica are on the brink of examining a subglacial lake that's been sealed off from the outside world for 14 million years. Cool!

For instance, take the “evolution debate” in this country. There is no debate about evolution in the scientific community. Sure, scientists are still researching questions that relate to evolution, but that’s because, as the great evolutionary biologist Theodosius Dobzhansky wrote in 1973, “Nothing in biology makes sense except in the light of evolution.” Evolution by natural selection is accepted by the scientific community, but boy-oh-boy do we still like figuring out exactly what it’s doing.

Last week, I told the story of the rough-skinned newts with the toxic skin and the garter snakes that eat them. I talked about the Red Queen Hypothesis and the evolutionary arms race, and all sorts of fun science-y terms that make basic interactions seem really, really impressive and cool. Today, I finish the story.

From the article:

“It takes all the running you can do, to keep in the same place,” says the Red Queen in Lewis Carroll’s Through the Looking Glass. If I were an economist or sociologist and psychologist, I’d talk about the struggle of making ends meets in this economy. But I’m a biologist, so I apply her royal words to the natural world. I’m not the first to do so: the Red Queen Hypothesis, an evolutionary theory about how species that interact must adapt, was inspired by that very quote.
