All polar bears alive today are descended from a single female brown bear who most likely hailed not from Alaska -- as widely presumed -- but from Ireland, scientists announced in July. The discovery, reported online in the journal Current Biology, suggests that polar bears and various species of brown bears probably encountered each other many times over the last 100,000 years or so as climate change forced them into each other's territory. On some occasions, those meetings produced hybrid offspring whose genetic signature lives on in polar bears today.
The metaphor "living Constitution" imports terms from biology into law and, in the process, relies on biology for its meaning. A proper understanding of biology is therefore central to understanding living constitutionalism. Yet despite its rampant use by both opponents and proponents of living constitutionalism, and despite the current fervent debate over whether biology can be useful to the law, no one has evaluated the metaphor from a biological perspective. This Essay begins that inquiry in an interdisciplinary study of law, science, and philology. The Essay first evaluates the metaphor as it is currently used and concludes that, while the metaphor is biologically accurate in some ways, it contains inaccuracies and gaps that render the metaphor incomplete. A deeper exploration of th...
LOS ANGELES - Young female chimps carry sticks as a form of "play- mothering," much in the same way girls cradle their dolls, scientists said Monday. The findings, published online in the journal Current Biology, imply that gender roles might be more biologically rooted than some people think, the authors said - and that might hold for human beings, too.
LOS ANGELES - Applying a mild electrical current to a particular part of the brain could improve mathematical abilities in people who suffer impaired skills or in patients who have suffered strokes or other neurological problems, British researchers report. The weak current apparently allows neurons to fire more freely, stimulating the ability to learn, the researchers reported in the journal Current Biology. Reversing the flow of the current made it more difficult for neurons to fire, impairing learning ability.
Applying a mild electrical current to a particular part of the brain could improve mathematical abilities in people who suffer impaired skills or in patients who have suffered strokes or other neurological problems, British researchers reported in November.

Reversing the flow of the current made it more difficult for neurons to fire, impairing learning ability.

ROCHESTER, N.Y., Sept. 17 /PRNewswire-USNewswire/ -- Cognitive scientists from the University of Rochester have discovered that playing action video games trains people to make the right decisions faster. The researchers found that video game players develop a heightened sensitivity to what is going on around them, and this benefit doesn't just make them better at playing video games, but improves a wide variety of general skills that can help with everyday activities like multitasking, driving, reading small print, keeping track of friends in a crowd, and navigating around town. In an upcoming study in the journal Current Biology, authors Daphne Bavelier, Alexandre Pouget, and C. Shawn Green report that video games could provide a potent training regimen for speeding up reactions in ma...
