Picky Female Frogs Drive Evolution Of New Species In Less Than 8,000 Y
Females typically have the upper hand in choosing mates, and this choice can rapidly give rise to new species, according to a study by UC Berkeley's Craig Moritz and Univ. of Queensland's Conrad Hoskin. They found a frog species in Australia that originated less than 8,000 years ago. Female choice amplified a difference that had evolved when the species was split in two a million years ago, creating reproductive isolation from both populations. Are Some Men Predisposed To Pedophilia?
Height may point to a biological basis for pedophilia. A new study found that pedophilic males were shorter on average than males without a sexual attraction to children, suggesting that pedophiles may have been exposed to pre-birth conditions that affected their physical development. The Oil Sands Environmental Research Network (OSERN): Frequently Asked
Questions and answers about obtaining petroleum from the "naturally occurring deposits of bituminous sand"(known as oil sand or tar sand) found near the Athabasca River in Canada. Includes information about mining, the kinds of environmental disturbance oil sands mining causes, and reclamation. Also includes maps and a link to a glossary of oil sands acronyms.

Duke University biochemists aided by Duke computer scientists and computational chemists have identified the likely way two key enzymes dock in an intricate three-dimensional puzzle-fit to regulate cell division. Solving the docking puzzle could lead to anticancer drugs to block the runaway cell division behind some cancers, said the researchers. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. Mixed Signals To Blame For Restless Legs Syndrome
Iron-deficient cells in the brain are mixing up central nervous system signals to the legs and arms causing the irresistible urges to move and creepy-crawly sensations that characterize restless legs syndrome (RLS), a Penn State College of Medicine study reports. Little Evidence Found For IVF As Most Effective Infertility Treatment
In vitro fertilization can improve pregnancy rates among couples with unexplained infertility, but there is little evidence to show whether IVF results in more live births than other treatments, according to a new review of recent studies. How The Neuron Sprouts Its Branches
Neurobiologists have gained new insights into how neurons control growth of the intricate tracery of branches called dendrites that enable them to connect with their neighbors. Dendritic connections are the basic receiving stations by which neurons form the signaling networks that constitute the brain's circuitry. To Catch An Intermediate: Scientists Find New Way To Trap And Hold Int
A new technique for capturing the short-lived but critical "intermediate"compounds that help carry chemical reactions which take place in aqueous solution from their starting point to the final product has been developed by researchers with the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). This technique basically entails temporarily trapping the elusive transients inside molecular pyramids. "That Laboratory of Abolitionism, Libel, and Treason": Syracuse and th
This exhibit explores the role of Syracuse, New York, in the Underground Railroad, the system that helped African American slaves escape to freedom. "Syracuse served as an important station along this freedom trail because of its central location on the Erie Canal and its associated waterways and travel routes."Includes digitized historical documents, maps and charts, and images of local abolitionists and reformers. From the Special Collections Research Center, Syracuse University Library.
