Aphorisms don't trump reality, however. They are but a frail, poignant protest against a Nature that disdains the most cherished human notions of order and elegance, truth and beauty.

But if quantum mechanics was a challenge to human sensibilities, this pesky Swiss-Italian neutrino is their undoing. It means that Einstein's relativity - a theory of uncommon beauty upon which all of physics has been built for 100 years - is wrong. Not just inaccurate. Not just flawed. But deeply, fundamentally, indescribably wrong.

It means that the "standard model" of subatomic particles that stands at the center of all modern physics is wrong.

In a development physicists are calling "huge," "tantalizing" and "unexpected," researchers have measured a signal that could herald a new kind of particle or force of nature.

Yet the finding is not yet conclusive, and leaves many researchers skeptical.

The discovery comes from an atom smasher called the Tevatron at the Fermilab physics laboratory in Batavia, Ill. Inside the accelerator there, particles are ramped up to near the speed of light as they race around a 4 mile (6.3 km) ring. When two particles collide, they disintegrate into other exotic particles in a powerful outpouring of energy.

The latest neuroscience research is presenting intriguing evidence that the brains of certain kinds of criminals are different from those of the rest of the population.

While these findings could improve our understanding of criminal behavior, they also raise moral quandaries about whether and how society should use this knowledge to combat crime.

The criminal mind

In one recent study, scientists examined 21 people with antisocial personality disorder -- a condition that characterizes many convicted criminals. Those with the disorder "typically have no regard for right and wrong. They may often violate the law and the rights of others," according to the Mayo Clinic.

Are humans causing a mass extinction on the magnitude of the one that killed the dinosaurs?

The answer is yes, according to a new analysis - but we still have some time to stop it.

Mass extinctions include events in which 75 percent of the species on Earth disappear within a geologically short time period, usually on the order of a few hundred thousand to a couple million years. It's happened only five times before in the past 540 million years of multicellular life on Earth. (The last great extinction occurred 65 million years ago, when the dinosaurs were wiped out.) At current rates of extinction, the study found, Earth will enter its sixth mass extinction within the next 300 to 2,000 years.

"The oldest fossilized shrimp in the world was recently discovered -- not in a coastal area, but in landlocked Oklahoma.

Geologists have been studying the ancient morsel, which was preserved in stone is as much as 360 million years old and was found in Oklahoma in remarkably good condition -- even the muscles of the fossil are preserved.

Rodney Feldmann, a professor at Kent State University in Ohio, explained that the sea critter was in Oklahoma because at the time, Oklahoma was the sea.

"It was preserved at a time when Oklahoma, and much of the rest of North America, was beneath sea level," Feldmann told FoxNews.com.

In fact, Oklahoma was so far beneath sea level as to be called "undersea." The U.S. geography was much different millions of years ago: A continent called Laramidia existed when a shallow sea flooded the central region of North America, isolating the eastern and western portions of the country for millions of years during the Late Cretaceous period.
