Newsroom Stories

Some WUSTL news stories never get old, and some just get better with time. WUSTL news editors picked 11 stories from 2011 — some new, some old — but all worth a second look as we head into 2012.

Lead pipes once used routinely in municipal water distribution systems are a well-recognized source of dangerous lead contamination, but new research from Washington University in St. Louis suggests that the partial replacement of these pipes can make the problem worse. The research shows that joining old lead pipes with new copper lines using brass fittings spurs galvanic corrosion that can dramatically increase the amount of lead released into drinking water supplies.

Any multicellular animal poses a special difficulty for the theory of evolution. Most of its cells will die without reproducing, and only a privileged few will pass their genes. Given the incentive for cheating, how is cooperation among the cells enforced? In the Dec. 16 issue of the journal Science, Washington University in St. Louis biologists Joan Strassmann and David Queller suggest the answer is frequent population bottlenecks that restart populations from a single cell.

Rita A. Stanley arrived at the School of Law in 1995. Since then, the scenery and her duties changed, but a constant was excellent co-workers. “People were the reason I loved it here,” Stanley says. Stanley, along with the other 102 staff members who retired from the university this past year, contributed a total of 2,023 years of service to the university — more than two millennia.

Freshman Matt Burkhardt (left) visits with Ian MacMullen, PhD, assistant professor of political science in Arts & Sciences. MacMullen and his wife, Lola Fayanju, MD, research fellow in the WUSTL Department of Surgery, co-hosted the party in their Gregg House residence. Faculty Fellows help integrate academic and residential life by living in the residential colleges with students for three-year stints.

With the holidays right around the corner, many parents are scanning the latest “recommended toy” lists as they make their final purchases. An education expert at Washington University in St. Louis says that, while educational toys are a fine idea, children receive the most benefit when their parents play with them and engage them in their new gifts. R. Keith Sawyer, PhD, associate professor of education in Arts & Sciences, offers advice to parents worried about making the right toy choices for their children.

Career Center advisers are encouraging students to make the most of the upcoming holiday break. The extended time off is a great chance to network and put plans into action, they say. Students are urged to self-evaluate, review their interests and options and update their resumes with recent experiences and new skills. 

High levels of tau protein in fluid bathing the brain are linked to poor recovery after head trauma, according to a study from Washington University School of Medicine in St. Louis and the Fondazione IRCCS Ca Granda-Ospedale Maggiore Policlinico in Milan, Italy. The results were reported online Nov. 23 in the journal Brain.

Michael Sherraden’s book, Assets and the Poor: A New American Welfare Policy, broke new ground on social policy in 1991. Twenty years later, its impact still is being felt around the world. In Assets and the Poor, Sherraden, PhD, the Benjamin E. Youngdahl Professor of Social Development at the Brown School at Washington University in St. Louis, writes that asset accumulation is structured and subsidized for many non-poor households, primarily via retirement accounts and home ownership. He argues that these opportunities should be available to all and proposes establishing individual savings accounts for the poor — also known as Individual Development Accounts (IDAs). Since Sherraden first proposed IDAs, they have been adopted in federal legislation and in more than 40 states.
