Roosters, famously, crow in the early morn -- but scientists don't fully understand why they unleash their voices when they do. After all, roosters have also been known to make a racket when other animals or birds are about, when a car starts, or when lights turn on in the middle of the night. So do they crow because they see the morning light, or because they hear other roosters? Or do they have some kind of internal body clock that lets them know that's it's time to unleash their peals?

Psychologist Timothy D. Wilson, a professor at the University of Virginia, expressed resentment in his Times Op-Ed article on Thursday over the fact that most scientists don't consider his field a real science. He casts scientists as condescending bullies: "Once, during a meeting at my university, a biologist mentioned that he was the only faculty member present from a science department. When I corrected him, noting that I was from the Department of Psychology, he waved his hand dismissively, as if I were a Little Leaguer telling a member of the New York Yankees that I too played baseball.

Today, a century and a half after Charles Darwin published "On the Origin of Species by Means of Natural Selection," the overwhelming majority of scientists in the United States accept Darwinian evolution as the basis for understanding how life on Earth developed. But although evolutionary theory is often portrayed as antithetical to religion, it has not destroyed the religious faith of the scientific community. According to a survey of members of the American Assn. for the Advancement of Science, conducted by the Pew Research Center in May and June this year, a majority of scientists (51%)

What if the solution to smog was right where the rubber meets the road? Scientists in the Netherlands have found that installing special air-purifying pavement on city streets can cut air pollution nearly in half. Researchers at Eindhoven University of Technology outfitted one block in the city of Hengelo, Netherlands, with paving blocks sprayed with titanium oxide, which has the ability to remove pollutants from the air and turn them into less harmful chemicals. The researchers left normal pavement on an adjacent street as a control.

Whether it's the vaccination that protects us from polio or the telephone that lets us talk with the neighbor down the street or around the world, our lives are enriched by the work of scientists. But what motivates people to study how and why things work, to dream up inventions that save lives or enable space travel? And why is it important to study galaxies or to view the activities of a single cell?

To many, human-animal chimeras--animals that contain human cells--sound like the stuff of nightmares. If you can picture a frog with a human head, a monkey with human vocal chords or a dog with opposable thumbs, you can see why some people want to put the brakes on any sort of scientific experiment that mixes cells from different species. The reality of chimeras is much less dramatic: Picture instead a pig that produces human insulin or a mouse getting chemotherapy for its human cancer cells.
