Washington University physicians use PET scans to track cervical cancer

A machine developed at Washington University to reveal the inner workings of brains and hearts is emerging as a premier tool for tracking cervical cancer. The device, called a positron emission tomography (PET) scanner, is similar to MRI scanners but uses radioactivity instead of X-rays to create images of blood flowing through organs, brain activity and other processes.

Bacteria that cause urinary tract infections invade bladder cells

Scanning electron microscopy image of a filamentous bacterium from a patient with a UTIScientists at the School of Medicine have found definitive proof that some of the bacteria that plague women with urinary tract infections (UTIs) are entrenched inside human bladder cells. The finding confirms a controversial revision of scientists’ model of how bacteria cause UTIs. Previously, most researchers assumed that the bacteria responsible for infections get into the bladder but do not invade the individual cells that line the interior of the bladder.

Return to Europa: A closer look is possible

NASA/JPLThick or thin ice shell on Jupiter’s moon Europa? Scientists are all but certain that Europa has an ocean underneath its surface ice, but do not know how thick this ice might be.Jupiter’s moon Europa is just as far away as ever, but new research is bringing scientists closer to being able to explore its tantalizing ice-covered ocean and determine its potential for harboring life. William B. McKinnon, professor of earth and planetary sciences at Washington University in St. Louis, is discussing some of these recent findings and new opportunities for exploring Europa in a news briefing on Thursday, Dec. 13, 2007, at the meeting of the American Geophysical Union in San Francisco.

WUSTL researchers spearhead key genome initiative

Twenty-eight-day-old *Physcomitrella* gametophyte showing the leafy gametophores in the center and the protonemal filaments radiating outward.The complete collection of genes — the genome — of a moss has been sequenced, providing scientists an important evolutionary link between single-celled algae and flowering plants. Just as the sequencing of animal genomes has helped scientists understand human genomic history, the sequencing of plant genomes will shed light on the evolution of the plant kingdom, according to Ralph S. Quatrano, Ph.D., the Spencer T. Olin Professor of Biology in Arts & Sciences at Washington University in St. Louis and the corresponding author of the paper.
