Andy Wain had to abandon the Sunday league match between Peterborough North End and a Royal Mail side in the 63rd minute after throwing down his whistle and marching up to confront North End's keeper. Research Casts Doubt On Circulating Stem Cells
Although adult stem cells taken from bone marrow are able to migrate into the muscle fibres, they do not generally take on any tissue-specific functions. This result of a study currently being conducted at Bonn's University Clinic means the cells would not serve as a substitute for defective muscle cells. The study is reported in the online section of the science journal PNAS (www.pnas.org, PNAS Early Edition). Car Buyers Say Silence Isn't Golden: Researchers Help Customers Litera
The technology improvements that are giving us ever quieter cars are not proving popular with many car drivers. Car manufacturers now want to restore to the inside of a car the sounds their customers want to hear while preserving the reduction in exterior noise. But what exactly do their customers want to hear? Researchers at the University of Warwick's Warwick Manufacturing Group are helping them answer that question. Discovery Links Blood Cell Defect To Common Lung Disorder, Leads To No
A persistent scarcity of oxygen in body tissues -- a widespread problem in patients with heart or lung disease -- can create a defect of red blood cells that further exacerbates the condition by constricting blood vessels in the lung, Howard Hughes Medical Institute researchers at Duke University Medical Center have found.

This exhibit looks at squamates (lizards and snakes), "[an] ancient group, whose scientific name is Latin for 'scaled,' [and which] is more diverse than mammals, as old as dinosaurs."Features photos and diagrams, essays on specific squamates and the relationships among these animals, video and sound clips, a webcam, and classroom materials. From the American Museum of Natural History. Biology of emergent Salmonella exposed: Deadly bug targets vulnerable
Researchers have characterized a deadly new strain of Salmonella, which emerged over an 18-month period. This type of Salmonella normally causes diarrhea and is rarely fatal but, by becoming resistant to antibiotics, acquiring the ability to spread from person to person, the new strain has become a health care challenge in Africa, killing up to one in four patients. The team suggests that emerging infections can be effectively tracked in the future using DNA sequencing technologies. Linguistic Research Moving In New Direction
Some linguistics researchers are applying larger scientific principles that describe natural forces to the study of language. This represents a major shift in linguistics research done over the last several decades. 3-D Ultrasound Identifies Women At Risk For Impending Preterm Birth
To help physicians non-invasively identify women at risk for preterm birth, 3-D ultrasound was used to measure the size of fetal adrenal glands, according to an abstract presented by Yale School of Medicine researchers at the Society for Maternal-Fetal Medicine Conference February 8 in San Francisco.
