Late Friday, Feb. 2, an overcast day in St. Louis, the twitter feed for the Super-TIGER cosmic ray experiment burst into life, as the Super-TIGER team received word that NASA’s Columbia Scientific Balloon Facility, which provides operations support for scientific ballooning in Antarctica, had decided to terminate the flight of the balloon carrying their detector aloft in the polar vortex.

Regina (Gina) F. Frey, PhD, associate professor of STEM education in the department of chemistry in Arts & Sciences and executive director of the Teaching Center, will be installed as the initial Florence E. Moog Professor of STEM Education on January 31, 2013.The professorship honors two of WUSTL’s women scientists, one past and one present, while also recognizing its deep commitment to excel in teaching the disciplines of science, technology, engineering and mathematics (STEM).

A massive earthen mound constructed about 3,200 years ago by Native Americans in northeastern Louisiana was built in less than 90 days, and perhaps as quickly as 30 days, according to new research in the journal Geoarchaeology. The site was recently nominated for a place on the UNESCO list of Word Heritage sites.

Coverage of the recent shipping crisis on the Mississippi River assumes that the appropriate response to a problem like low water levels is to find an engineering solution. Washington University in St. Louis hydrogeologist Robert E. Criss disagrees. He feels the river has been over-engineered and that many of the engineering “solutions” are not economic if all of their costs, including those to the taxpayer and to the environment, are taken into account.

Healthy men and women show little difference in their hearts, except for small electrocardiographic disparities. But new genetic differences found by Washington University in St. Louis researchers in hearts with disease could ultimately lead to personalized treatment of various heart ailments.

Over the holiday weekend, the WUSTL-led cosmic ray experiment Super-TIGER set a record for the longest flight ever made by a heavy-liftscientific balloon. Now aloft for 45 days, shattering the previous record of 42 days, it has recorded more than 50 million “events,” or hits by cosmic rays arriving from space. The scientists are ecstatic to have such a great balloon because the longer the it stays up, the more data they will collect and the more they will learn about the mysterious mechanism that accelerates these particles and sends them streaming across space.

Scientists at Washington University in St. Louis long suspected that dueling findings about the impact of invasive species on biodiversity reflect the different sizes of study sites. Now field work confims that the impact of invasive species is different at small scales than at large ones. The scientists hope an understanding of this “scale dependence” will help settle arguments that have broken out in the scientific community and discourage recent popular science articles downplaying the damage invasives cause.

Washington University’s business, engineering, and law schools are collaborating on a new course in 2013 that will embed students in the center of the thriving entrepreneur community in downtown St. Louis. Students will trade their campus classroom for working space at T-REx, a new St. Louis tech incubator that offers startup companies affordable offices in the historic Railway Exchange Building.

We would all like to believe that there is a kind of karma in life that guarantees those who cheat eventually pay for their bad behavior, if not immediately, then somewhere down the line. But a study of a new gene in the amoeba Dictyostelium discoideum suggests that, at least for amoebae, it is possible to cheat and get away with it.

 Super-TIGER  the WUSTL-led cosmic ray experiment, has just been given the green light for  a third circuit around Antarctica. If the balloon stays up for a complete circuit it will probably break the heavy-lift scientific ballooning record of 42 days — and bring in a rich haul of data about cosmic rays, charged particles that continually bombard the Earth from space. The team has gone positively piratical over the prospect of more booty.
