Goodbye Mr Nice Guy


Just in time for Valentine's Day, researchers have turned up some new answers to the age-old question of what we want in our partners.

Academics question surge's success in Baghdad


By tracking the amount of light emitted by Baghdad neighborhoods at night, a team of geographers has uncovered evidence that the U.S. troop surge in Iraq may not have been as effective at improving security as the administration has suggested and that ethnic cleansing by rival Shiites may have been largely responsible for the decrease in violence for which the U.S. military has claimed credit...

Homo Superior


Genetic engineering is getting serious. Recently researchers have shown that "hardwired" responses - such as fear - can be manipulated and even reversed, that extreme muscle growth is possible, and that sexual preference can be changed. But if we create a race of superhumans, would this lead to a golden age of peace, love, and understanding; or would it be business as usual?

Too Cool For The 21st Century


Cryonics is what you might better know as a sci-fi plot device; think suspended animation or stasis. But rather than journeying to a distant planet, cryonic aficionados will stay on Earth in the hope that they can be revived in the future and cured of whatever ails them in this life. Or even better, that future medical science might have found a way to give them immortality...

Americans have fewer close, personal friends than they used to.

Sexual Success And The Schizoid Factor


Ever wondered why scruffy rock chicks are pursued by legions of doting male fans? Or why women threw themselves at Pablo Picasso? Well, a new study suggests that creativity may confer an evolutionary advantage in finding a mate.

Is there enough evidence to support the idea that artistic creativity is an evolutionarily beneficial effect of schizoid tendencies?

The Rain In Spain Falls Only In The Human Brain


New research suggests that humans have an innate and universal faculty to form sentences, supporting the idea that we are born with a ready-made language "module" in our brain.

Food, Notorious Food


Our ancestors had it pretty tough when it came to feeding the family. Leaving the cave to spear something for dinner was fraught with danger and disappointment.
