Solar energy has the power to reduce greenhouse gases and provide increased energy efficiency, says a scientist at the U.S. Department of Energy's Argonne National Laboratory, in a report (view it…

A Georgia Tech researcher has discovered that for tasks involving spatial processing, preparing for the task and performing it are not two separate brain processes, but one – at least when there are…

Genetic tests using blood samples already are used to diagnose some diseases and even personalize treatment. Now it is possible to develop similar tests that reveal a person's potential to become…

A few days ago on the Dean Edell radio show, I’m told, Dean Edell told his listeners that nicotine patches don’t cause any addiction problems; people just don’t get addicted to them. To anyone who…

Ever since the logical positivists in the early 20th century, there has been a debate over whether science has made metaphysics obsolete. Is science all we need to describe and understand the…

Tooth-brushing may trigger seizures in certain people with epilepsy, and researchers say lesions in a specific part of the brain may be a cause in some people, according to an article published in…

Speed daters who romantically desired most of their potential partners were rejected quickly and overwhelmingly, according to a new Northwestern University study. Conventional wisdom has long…

Which navy commissioned the boat that sunk off the coast of Acre 200 years ago, which battles was it involved in and how did it end up at the bottom of the sea? The recent findings of marine…

Researchers at the U.S. Department of Energy's Argonne National Laboratory have developed an advanced concept in nanoscale catalyst engineering – a combination of experiments and simulations that…

Researchers at Rensselaer Polytechnic Institute have discovered what likely triggered the eruption of a "supervolcano" that coated much of the western half of the United States with ash fallout 760…

"The Sopranos" have some competition -- brown-headed cowbirds. Cowbirds have long been known to lay eggs in the nests of other birds, which then raise the cowbirds’ young as their own. Sneaky,…

Students of the evolution of social behavior got a big boost with the publication of the newly sequenced honeybee genome in October 2006. The honeybee (Apis mellifera) belongs to the rarified cadre…

For a lucky subset of vertebrates, losing an appendage is no big deal. As many an inquisitive child knows, salamanders can regenerate lost limbs or tails; and as lab investigators know, zebrafish…

Superconductivity -- the conduction of electricity with zero resistance -- sometimes can, it seems, become stalled by a form of electronic "gridlock." A possible explanation why is offered by new…

Why do some individuals sacrifice their own self-interest to help others? The evolution and maintenance of cooperative behavior is a classic puzzle in evolutionary biology. In some animal societies,…

Using a modified ink-jet printer, a McGill University researcher is producing three-dimensional bioceramic “bones” that could one day change the way reconstructive surgery is performed. McGill…

The fact that female wasp spiders have numerous sexual contacts is something which their male partners cannot prevent. What they can do, however, is ensure that no offspring ensue from these tête à…

Psychologists have been fond of stating in recent years that human happiness, or what psychologists call subjective well-being, is largely independent of our life circumstances. The wealthy aren’t…

There seems to be a trend occuring in society that is trying to unify the science humanity has cultured and cradled  in order to explain objectively the existence of observable phenomena with…

I have been studying electromagnetism lately, as in the practical application of Maxwell's equations to realistic physical systems. I find it an amazing fact, that even if we assume that point…
