Duck-billed dino crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected -- the sense of smell.

New study explores beetle species with two forms of females
A fascinating new study from the forthcoming issue of The American Naturalist attempts to explain the mysterious persistence of two forms of females in many diving beetle populations. Their findings have important implications for theories of sexual conflict, which arises when the costs and benefits of multiple matings differ for males and females.

Mute swan population helps explain longstanding evolutionary question
In an important new study forthcoming from The American Naturalist, biologists from the University of Oxford tracked a colony of mute swans for more than two decades to explore a longstanding evolutionary question: whether the number of eggs laid by a female bird known as "clutch size" changes in accordance with natural selection.

Alcoholism: Clinical & Experimental Research
Daughters of alcoholics
During the last decade, most of the research on genetic and environmental variables relevant to children of alcoholics has focused on the sons of alcoholics. In contrast, symposium participants at the annual meeting of the Research Society on Alcoholism in Vancouver, Canada in June 2004 focused on moderators of risk for alcoholism and other psychopathologies among daughters of alcoholics. Proceedings are published in the February issue of Alcoholism: Clinical & Experimental Research.

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.

Heart-healthy compound in chocolate identified
In a multifaceted study involving the Kuna Indians of Panama, an international team of scientists has pinpointed a chemical compound that is, in part, responsible, for the heart-healthy benefits of certain cocoas and some chocolate products.

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.
