In collaboration with the National Cancer Center, Singapore, Van Andel Research Institute (VARI) researchers have identified an enzyme that could help diagnose and treat cholangiocarcinoma, a form of liver cancer that strikes up to 3,000 new patients each year in the United States.

Transportation engineering PhD student Zhixia Li was attracted to the University of Cincinnati because of the real-world education and experience the university provides. In return, he's headed a real-world project that every driver can relate to. It's a project on which he has presented and published nationally, and it looks at what he calls the "yellow light dilemma." Are you, as a driver, more likely to stop or to speed through a yellow light?

Scientists and others from 25 countries convened in April to focus on advancing new tools to humanely manage populations of pet and un-owned cats and dogs. The $75 million Michelson Prize & Grants in Reproductive Biology, launched in October 2008 by Found Animals Foundation, is inspiring researchers worldwide to focus on the goal of finding new non-surgical approaches to reproduction control.

Bodychecking in Pee Wee hockey (with players aged 11-12) more than triples the risk of concussion and injury, according to a new study by researchers at the University of Calgary.

An assessment of nearly 70 ambulatory surgical centers in three states found that lapses in infection control were common, including for practices such as hand hygiene, injection and medication safety and equipment reprocessing, according to a study in the June 9 issue of JAMA.

From 1997 to 2006, the number of long-term acute care hospitals doubled, the number of Medicare patients who were transferred to a long-term acute care hospital after a critical illness tripled, and the 1 year survival for these patients was poor, according to a study in the June 9 issue of JAMA.

An outbreak of infection due to linezolid and methicillin-resistant Staphylococcus aureus (LRSA) in 12 intensive care unit patients in Spain was associated with transmission within the hospital and extensive usage of the antibiotic linezolid, often used for the treatment of serious infections, with reductions in linezolid use and infection-control measures associated with resolution of the outbreak, according to a study in the June 9 issue of JAMA.

A comparison of hockey leagues in Canada for 11-12 year old players finds that compared with leagues that do not allow body checking, those that do have an associated three-fold increased risk of game-related injuries, including severe injuries and severe concussions, according to a study in the June 9 issue of JAMA.

This potentially paradigm-shifting procedure may successfully salvage brain cells for more than just the first three hours following a major stroke, with fewer risks.

Johns Hopkins experts have found that men enrolled in an active surveillance program for prostate cancer that eventually needed surgery to remove their prostates fared just as well as men who opted to remove the gland immediately, except if a follow-up biopsy during surveillance showed high-grade cancer.

A blood vessel-blocking drug called tasquinimod slowed the rate of disease progression in a clinical trial of 200 prostate cancer patients, according to experts at Johns Hopkins, Roswell Park Cancer Institute and Duke University.

The Tropical Rainfall Measuring Mission satellite, known as TRMM is a "flying rain gauge" in space, and can provide rainfall estimates from its position in orbit around the Earth. Data accumulated from TRMM enabled visualizers to create a map of rainfall generated by Cyclone Phet as it marched through the Arabian Sea from May 31 to June 6. The heaviest rainfall occurred over open waters, but Phet dropped very heavy rainfall over parts of Oman and Pakistan.

Surgeons at Johns Hopkins have safely and effectively operated inside the brains of a dozen patients by making a small entry incision through the natural creases of an eyelid to reach the skull and deep brain.

NASA has successfully completed a comprehensive pre-shipment review of the Fast, Affordable, Science and Technology Satellite, or FASTSAT, a small, microsatellite class spacecraft bus that will carry six experiment payloads to low-Earth orbit.

Queen's University Brian Amsden is hoping that in about 10 years a tendon, spinal cord or heart valve will be able to regenerate itself after an injury or disease. The chemical engineering professor, along with scientists from the University of Western Ontario and University of Toronto, is currently trying to develop microscopic polymer fibers to help rebuild human tissue and speed the healing process.
