Public schools equal or better in math than private or charter schools
Contrary to common wisdom, public schools score higher in math than private ones, when differences in student backgrounds are taken into account. That was the conclusion of researchers Sarah and Christopher Lubienski in a study last year of data from the 2000 National Assessment of Educational Progress. Now they're back with similar and more-extensive results in a follow-up study.

Martian snow source of tropical glaciers, research team reports
Recent images beamed from Mars reveal intriguing evidence of glacial deposits in the tropics of the Red Planet. But how did this Martian ice form so far from the poles? Ancient snows, according to new research appearing in Science.

Indigenous Amazonians display core understanding of geometry
Researchers in France and at Harvard University have found that isolated indigenous peoples deep in the Amazon readily grasp basic concepts of geometry such as points, lines, parallelism and right angles, and can use distance, angle and other relationships in maps to locate hidden objects. The results suggest that geometry is a core set of intuitions present in all humans, regardless of their language or schooling.

Current Anthropology
Ahead of the game
The disappearance of Neanderthals is frequently attributed to competition from modern humans, whose greater intelligence has been widely supposed to make them more efficient as hunters. However, a new study forthcoming in the February issue of Current Anthropology argues that the hunting practices of Neanderthals and early modern humans were largely indistinguishable, a conclusion leading to important implications for debates surrounding behavioral evolution and the practices that eventually allowed modern humans like ourselves to displace other closely-related species.

Half of active children pursue non-traditional physical activities
A transportation engineer at The University of Texas at Austin has performed one of the most comprehensive surveys of physical activity in children and found that about as many kids stay active by peddling their bikes to a friend's house or walking around a neighborhood as do others by participating in organized athletics.

First impressions of beauty may demonstrate why the pretty prosper
We might not be able to resist a pretty face after all, according to a report from the University of Pennsylvania. Experiments in which subjects were given a fraction of a second to judge "attractiveness" offered further evidence that our preference for beauty might be hard-wired. Their results offer a look at cognitive processes behind a very real phenomenon: physically attractive people have advantages that unattractive people do not.

Genome sequencing is for ecologists, too
An organism widely used for genetics-versus-environment studies has joined the panoply of mice, rats, dogs, humans and other species whose entire genomes have been sequenced. At the Daphnia Genomics Consortium's annual meeting in Bloomington this week, Indiana University and Joint Genome Institute scientists announced they've completed a "shotgun" sequence for Daphnia pulex, or the water flea, as it's better known to high school biology students.

Growth hormone, obesity can trigger sleep apnea in some kids
Growth hormone was approved in the United States to treat Prader-Willi in 2000, but several children with the disease died after beginning the treatments. All died in their sleep and had been battling infections. To understand the problem, University of Florida researchers decided to study how growth hormone affected sleep.

In the mind's eye: How the brain makes a whole out of parts
When a human looks at a number, letter or other shape, neurons in various areas of the brain's visual center respond to different components of that shape, almost instantaneously fitting them together like a puzzle to create an image that the individual then "sees" and understands.
