Clinical pathways have been used in surgeries since the 1980s, but their nature and usefulness are still subjects of much debate, especially as procedures such as hip and knee joint replacement represent a significant cost to hospitals. Now authors publishing in the open access journal BMC Medicine have concluded that using clinical pathways can effectively improve the quality of the care provided to patients undergoing joint replacement.

Use of several older and newer biomarkers appears to offer minimal added benefit in the prediction of cardiovascular events compared to conventional risk factors such as high cholesterol and high blood pressure, according to a study in the July 1 issue of JAMA.

ANN ARBOR, Mich.---Researchers at the University of Michigan have devised a microscale tool to help them understand the mechanical behavior of biofilms, slimy colonies of bacteria involved in most human infectious diseases.

Most bacteria in nature take the form of biofilms. Bacteria are single-celled organisms, but they rarely live alone, said John Younger, associate chair for research in the Department of Emergency Medicine at the U-M Health System. Younger is a co-author of a paper about the research that will be the cover story of the July 7 edition of Langmuir.

It's a frequent scene in television crime dramas: Clever police technicians zoom in on a security camera video to read a license plate or capture the face of a hold-up artist. But in real life, enhancing this low-quality video to focus in on important clues hasn't been an easy task. Until now.

The Institute of Medicine (IOM) Committee on Comparative Effectiveness Research (CER) released its recommendations today for setting health care priorities for research and funding by the U.S. government. Co-chairs of the committee, Harold C.

While screening for possible pulmonary emboli using pulmonary CT angiography, a new study shows that radiologists can effectively lower the patient radiation dose by approximately 44% and improve vascular enhancement without deterioration of image quality, according to a study performed at Brigham and Women's Hospital and Harvard Medical School, Boston, MA.

The vast amount of carbon stored in the arctic and boreal regions of the world is more than double that previously estimated, according to a study published this week.

The amount of carbon in frozen soils, sediments and river deltas (permafrost) raises new concerns over the role of the northern regions as future sources of greenhouse gases.

"We now estimate the deposits contain over 1.5 trillion tons of frozen carbon, about twice as much carbon as contained in the atmosphere", said Dr. Charles Tarnocai, Agriculture and Agri-Food Canada, Ottawa, and lead author.

Researchers in the Department of Physics and Astronomy at the University of Leicester have developed a new synthesis method, which has led them to the discovery of fluorescent silicon nanoparticles and may ultimately help track the uptake of drugs by the body's cells.

A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology--similar to that found in computers and cell phones. The new processor is far from conventional, however, in that it uses the potent power of quantum mechanics to bring the dream of quantum computing a small but significant step closer to reality.

The UK spends around £2.5 billion each year on dental materials to replace or strengthen teeth*. The Chewing Robot is a new biologically inspired way to test dental materials and it will be shown to the public for the first time at this year's Royal Society Summer Science Exhibition [30 June to 4 July].

Researchers at the University of Bristol's Department of Mechanical Engineering in collaboration with the Department of Oral and Dental Science have developed the Chewing Robot to study dental wear formation on human teeth.
