To operate a nuclear power plant like Three Mile Island, hundreds of highly trained employees must work in concert to generate power from safe fission, all the while containing dangerous nuclear wastes. On the other hand, it’s been known for 30 years that Mother Nature once did nuclear chain reactions by her lonesome. Now, researchers at Washington University in St. Louis have analyzed the isotopic structure of noble gases produced in fission in a sample from the only known natural nuclear chain reaction site in the world in Gabon, Wes Africa, and have found how she does the trick.

Washington University in St. Louis has licensed a system developed by Washington University engineers that is meant to detect counterfeit credit cards by reading a unique magnetic “fingerprint” on the stripes of credit cards and other objects that carry magnetic information. The system — called Magneprint — was invented by Ronald Indeck, Ph.D., Das Family Distinguished Professor of Electrical Engineering at Washington University.

PET scans: normal (top 2 rows) and Alzheimer’s.After decades of searching, scientists finally may have identified a way to study Alzheimer’s disease changes in living human brains. Researchers at Washington University’s Alzheimer’s Disease Research Center (ADRC) have begun studies of an imaging agent developed at the University of Pittsburgh that could potentially detect amyloid plaques with a positron emission tomography (PET) scan, enabling earlier detection of the disease and improved testing of new treatments.

Is this a “cup” or a “mug?”No matter how hard we try to change our behaviors, it’s the old ways that tend to win out over time, especially in situations where we’re rushed, stressed or overworked, suggests a new study of human memory from Washington University in St. Louis. The findings are bad news for people struggling to change harmful behaviors, such as smoking or overeating, and good news for people who establish healthy lifestyles at an early age. Even when we consciously try to put new good intentions into place, those previously learned habits remain stronger in more automatic, unconscious forms of memory.

At issue in the Kelo v. City of New London case before the Supreme Court is a redevelopment project in the downtown and waterfront areas of this economically distressed Connecticut city. Private property must be taken by condemnation in eminent domain and turned over to the developer to carry out the project. “In Kelo v. City of New London, the Supreme Court has taken a major case that will test the ability of municipalities to carry out redevelopment projects to improve their downtowns and city neighborhoods,” says Daniel Mandelker, the Howard A. Stamper Professor of Law at Washington University in St. Louis and one of the country’s leading scholars and teachers in land use law. Mandelker believes the Connecticut court properly upheld the use of eminent domain in this case, but that abuses can occur in other cases where there is no clear redevelopment objective.

Tips for kicking the butts.The Great American Smokeout — the day each November the American Cancer Society encourages smokers to say “no thanks” to cigarettes for 24 hours — helps many people recognize how dangerous smoking is and how much they really want to quit, says a psychologist at Washington University in St. Louis who is an expert on helping people gain control of personal habits.

Keith Brandt performs a breast reconstruction using the TRAM flap procedure.When a breast cancer patient requires a mastectomy, cancer surgeons and reconstructive plastic surgeons at the Siteman Cancer Center at Barnes-Jewish Hospital and WUSM now perform a technique called the TRAM (traverse rectus abdominus myocutaneous) flap procedure, which allows surgeons to use the patient’s own tissues to recreate a natural breast.
