WUSTL researchers are investigating how to infuse grains with folate typically found in green vegetables such as broccoli.A team of researchers led by Karel Schubert, Ph.D., affiliate research biology professor in Arts & Sciences at Washington University in St. Louis, recently achieved a breakthrough to enhance levels of folate, a vitamin essential to human and animal health, in the model plant Arabidopsis.

People who are enrolled in Medicare Choice HMO plans with drug coverage die at about the same rate as those in traditional fee-for-service Medicare plans, but mortality rates for those in Medicare HMO plans without drug coverage are substantially higher. That’s the conclusion of a recent study done by Gautam Gowrisankaran, Ph.D., an assistant professor of economics at the Olin School of Business of Washington University in St. Louis, with University of Minnesota colleague Robert J. Town. The researchers’ estimates imply that a 10-percentage point shift in coverage from fee-for-service to HMO plans without drug coverage could result in 51,000 additional deaths per year among the elderly.

An electron micrograph of strep bacteria infecting muscle tissueMicrobiologists at the School of Medicine discovered that Strep A, the bacteria responsible for strep throat and other more serious disorders, has a wasplike “stinger” it uses to infect cells. Scientists had expected to find a random profusion of pumps for spraying infection-related compounds. The newly discovered, dedicated stinger could prove to be an easier target for new infection-preventing drugs.

Joe Angeles / WUSTL PhotoA new book co-authored by a memory researcher at Washington University in St. Louis is one-stop shopping for all the questions we have about memory and how serious our lapses might be as we grow older. Mark A. McDaniel, Ph.D., professor of psychology in Arts & Sciences at WUSTL, says his book, Memory Fitness: A Guide for Successful Aging, relies on many rigorous academic studies but is written for the lay person. “Our mission is to give the general public a good idea of what they can reasonably expect from their memory capabilities as they age,” says McDaniel about the book he co-authored with Gilles O. Einstein, Ph.D., professor and chair of the psychology department at Furman University. “It also outlines some reasonable expectations about things people can do to perhaps increase their memory performances.”

It can happen at any time of year for any number of reasons: a strong spring thunderstorm; an increased demand for air conditioning; heavy snow or ice on power lines or tree limbs; or even a wayward driver crashing into a utility pole. Whatever the cause, a power outage can spoil more than just that TV show you’re watching or the book you’re reading. A lack of refrigeration can jeopardize the safety of food. But what do you need to pitch and what can you keep once the power comes back on?

“Give me a one-armed economist,” President Harry S. Truman once demanded as he vented his frustration over economic advisors who offer straightforward recommendations, then hedge their bets by tacking on a slew of caveats, often beginning with the phrase “but, on the other hand…” Now, Murray Weidenbaum, the chairman of President Ronald Reagan’s first Council of Economic Advisers, has published a compilation of essays that offers the clear, no-nonsense economic policy analysis that Truman craved. Titled One-Armed Economist: On the Intersection of Business and Government, the book provides a distillation of four decades of Weidenbaum’s writings on key public policy issues.

Washington University has a number of internationally recognized experts and researchers on terrorism and homeland security who can address issues including intelligence, critical infrastructure, cybersecurity, target identification, and many other areas of concern related to the latest news on threats to the U.S. Faculty associated with the University’s Center for Security Technologies may be of […]

Everyone sweats, but it’s unlikely many people ever consider the social and economic impact of our bodies’ built-in air conditioning system. With summer’s hottest days likely still to come, Michael Heffernan, assistant professor of dermatology at the School of Medicine, helps St. Louis Post-Dispatch writer Jeff Daniels take a closer look at this hot topic.

Scientists have known for years that eating less tends to make animals live longer, but no one is quite sure why. Several School of Medicine researchers studying the effects of caloric restriction on humans may help provide an answer to that question. This story was written by Tina Hesman and published by the St. Louis Post-Dispatch.
