Differences in gene usage dramatically change bacteria’s ‘lifestyles’
When and where a bacterium uses its DNA can be as important as what’s in the DNA, according to WUSM researchers. Scientists found significant differences in two bacterial organisms’ use of a gene linked to antibiotic resistance. The distinction alters the bacteria’s “lifestyles,” or their ability to survive in different environments.
Gene D. Thin Elk, creator of the Red Road Approach, to lecture Nov. 30 at the George Warren Brown School of Social Work
Gene D. Thin Elk, one of the nation’s leading authorities on treatment for alcoholism, will present a lecture on the “Red Road Approach to Wellness and Healing” 4:30 p.m. Nov. 30 in Brown Lounge. The Red Road approach, created by Thin Elk, uses Native American traditions and values as part of a drug and alcohol rehabilitation program. The lecture, which is free and open to the public, is sponsored by the Kathryn M. Buder Center for American Indian Studies at the George Warren Brown School of Social Work and the American Indian Student Association.
Heart responds to fasting by remodeling vital energy-producing components
Researchers at the School of Medicine have identified a previously unsuspected response by mouse heart muscle cells to fasting conditions: the cells’ power generators, the mitochondria, appear to remodel and consume extra internal walls or membranes in an effort to supply energy to the rest of the cell.
Planning Reform in the New Century conference to be held Dec. 3-4
Legal scholars, planners and political scientists from the Midwest will come together at WUSTL School of Law Dec. 3-4 to discuss the opportunities for reform in planning and land use regulation. Rep. Marcy Kaptur and Paul Farmer, president of the American Planning Association, will service as conference keynote speakers. The conference features two days of panel discussions on political leadership in planning statute reform, contemporary planning efforts, sprawl and urban growth, housing and regulatory streamlining, and the impact of state and local planning programs.
Study details how Bush might reshape U.S. Supreme Court
Sandra Day O’ConnorPresident Bush’s re-election, coupled with strengthened Republican control of the Senate, has fueled speculation that the next four years could bring about dramatic shifts in political composition of the U.S. Supreme Court. While Bush may be poised to push the court in a more conservative direction, a forthcoming study suggests his ability to make dramatic ideological changes still hinges on whether he has the opportunity to replace Justice Sandra Day O’Connor.
Washington University CubeSat readied for NASA/Air force competition
David Kilper / WUSTL PhotoFailure at a university is a word with bad connotations, unless you are involved in building experimental satellites that the U.S. Air Force and NASA find interesting. An aerospace engineer at Washington University in St. Louis who works with students building experimental spacecraft says student-built spacecraft, which he calls “university-class,” have a strong advantage over aerospace industry-built spacecraft: the freedom to fail.
Depression, suicide are the major health issues facing college students, says student health director
One in three college students is depressed.The numbers are startling. National studies have shown that one in three college students is depressed and one in four contemplates suicide. Why are young people so much more anxious and stressed than previous generations? What can be done to solve this problem? Alan Glass, M.D., director of Student Health and Counseling at Washington University in St. Louis, says recognizing the signs of depression and suicidal tendencies and keeping the lines of communication open are key to diverting a tragedy.
Imaging technique detects plaques in Alzheimer’s disease
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.
Old habits, both good and bad, are hard to break, suggests study of human memory
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.
Magneprint technology licensed to TRAX Systems, Inc.
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.
