It’s a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic organisms, including humans.

An expert on the Second Amendment says that gun owners and sellers should not be sweating bullets over Barack Obama’s election as president. Despite Obama’s record on gun control, David T. Konig, Ph.D., a professor of history in Arts & Sciences and a professor of law at Washington University in St. Louis, says that the right of the people to keep and bear arms will not be an issue that Obama will address as president early in his term — if at all.

The more an animal walks during the day, the less energy it has to reproduce. Makes sense right? Not so fast, say two WUSTL researchers. They claim, based on a study of 161 mammalian species, that on average, animals which travel the longest distance each day to find food have the most offspring. The study, the first of its kind aimed at disproving the long-standing theory that more walking equates to less reproduction, was conducted by Herman Pontzer, Ph.D., assistant professor, and Jason Kamilar, Ph.D., research associate, both in anthropology in Arts & Sciences.

Joshua Maurer, Ph.D., assistant professor of chemistry in Arts & Sciences at Washington University in St. Louis, has received a four-year, $1,216,000 grant from the National Institute of Mental Health for research titled, “Unraveling Development: New Materials for Understanding Neuronal Wiring.” Maurer’s long term objective is to develop methodology that allows the study of a variety of neuronal wiring processes. He is starting by unscrambling a phenomenon known as midline crossing using zebrafish. During development, neurons from the right eye cross the midline of the brain to make a connection in the left hemisphere.

Six faculty members from Washington University in St. Louis have been named fellows of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. The highest honor awarded by AAAS, the rank of fellow is bestowed upon members by their peers in recognition of scientifically or socially distinguished efforts to advance science or its applications.

Frank K. FlinnIn November, California citizens passed Proposition 8 upholding the idea that marriage is defined as and limited to the union of one man with one woman. The vote has given encouragement to many in other states who want to pass similar legislation. The United States is about to enter a period of legal upheaval on the question of marriage in the civil law, suggests Frank K. Flinn, Ph.D., adjunct professor of religious studies in Arts & Sciences. His proposal? Give marriage to the churches and let the state define civil unions.

Today, scales are plain, but in the 19th century, they were garbed in polished wood and semi-precious stones.Stepping onto a scale after a calorie-filled holiday season isn’t an activity many 21st-century Americans relish. But in the late 19th century, scales were all the rage at festive gatherings — the 1800s’ answer to Guitar Hero. “A family would think it fun to weigh themselves before and after a big holiday dinner to see how much they had gained,” said Deborah I. Levine, Ph.D. “Knowing your weight was a novelty, a kind of parlor trick, before scales became widely available through mass production.”

TrinkausNew research published by Erik Trinkaus, Ph.D., professor of anthropology in Arts & Sciences, establishes a late persistence of Neadertals in southwestern Europe some 40,000 years ago. The research sheds light on what were probably the last Neandertals on earth.

As President-elect Barack Obama continues to fill key cabinet positions from the ranks of D.C.-based public policy think tanks, a new book by longtime policy adviser Murray Weidenbaum examines how the nation’s top think tanks came to play such critical roles in U.S. politics.

Using what cognitive psychologists are discovering in the laboratory to improve learning in the classroom is the goal of a $6.47 million collaborative activity grant to Washington University from the James S. McDonnell Foundation.
