ROCHESTER, Minn. -- Cologuard stool DNA testing for colorectal cancer was found to be an accurate noninvasive screening option for Alaska Native people, a population with one of world's highest rates of colorectal cancer, concluded researchers from the Alaska Native Tribal Health Consortium and Mayo Clinic.

Washington, DC - October 30, 2015 - Biofilms--mats of bacteria similar to the plaque that grows on teeth--frequently coat the surfaces of catheters, and of various medical implants and prostheses, where they can threaten lives or lead to failure of the implants. Antibiotics are impotent against biofilms. Now Jakub Kwiecinski, PhD, Tao Jin, MD, PhD, and collaborators show that coating implants with "tissue plasminogen activator" can prevent Staphylococcus aureus, the leading cause of hospital-acquired infections, from forming biofilms.

MADISON, Wis. -- Couples raising a child with developmental disabilities do not face a higher risk of divorce if they have larger families, according to a new study by researchers from the Waisman Center at the University of Wisconsin-Madison.

The study, published in the American Journal on Intellectual and Developmental Disabilities, also compares divorce rates of couples who have at least one child with a developmental disability to that of their peers who have typically developing children.

The Ebola virus acts fast. The course of infection, from exposure to recovery, or death, can take as little as two weeks. That may not leave enough time for the immune system to mount an effective response.

KNOXVILLE--Lack of adequate sleep can do more than just make you tired. It can short-circuit your system and interfere with a fundamental cellular process that drives physical growth, physiological adaptation and even brain activity, according to a new study from the University of Tennessee, Knoxville.

Albrecht von Arnim, a molecular biologist based in the Department of Biochemistry and Cellular and Molecular Biology, studied plants but said the concepts may well translate to humans.

An international group of pollination experts - including a University of Guelph professor - has published a second summary in as many years on the scientific evidence about the effects of neonicotinoid pesticides on bees.

The report was published this week in Proceedings of the Royal Society B.

A promising new metal alloy system could lead to commercially viable magnetic refrigerants and environmentally friendly cooling technologies, according to a scientist at Rochester Institute of Technology.

Reptiles are often chosen as pets when an allergy risk exists within a family and the choice is made to avoid potentially allergenic pets such as dogs, cats or guinea pigs. Researchers at the Messerli Research Institute, however, recently described a noteworthy clinical case in which an eight-year-old boy developed nightly attacks of severe shortness of breath four months after the purchase of a bearded dragon.

At the University of Cologne, biophysicists in the lab of Professor Berenike Maier were now able to show how differential mechanical forces can lead to cell sorting in biofilms, thereby determining their architecture. In their publication in the journal eLife, the team headed by the biophysicist Enno Oldewurtel showed how specific mechanical forces can be the key to the structure of a biofilm. Bacteria with different surface structures organized themselves in a "tug of war": the cells actively moved in the direction in which they could pull the strongest onto neighboring bacteria.

There is a hint of a benefit of pulse oximetry screening as an add-on test to existing standard examinations for detection of critical congenital heart defects in newborns: More cases are detected by additional screening than by the two clinical examinations U1 and U2 alone. This means that newborns can be treated at an early stage and may be protected from severe late complications.

Online services in the EU are highly fragmented: Europeans surf mostly on US-based websites which account for about 54% of online activity, while activity on EU-based websites accounts for 42%, according to a new JRC report. Only 4% of the EU's online services activity takes place on websites from other parts of the world.

HONOLULU - A panel of markers have been discovered that helps identify if a person is pre-diabetic by measuring the fatty acids in their blood. This discovery by University of Hawai'i Cancer Center researchers may allow physicians to warn patients years before the onset of diabetes, therefore allowing them to change their lifestyle patterns potentially avoiding the diagnosis of a chronic disease.

"This 'rotation model', which made the cover of BioEssays, represents a true paradigm shift in the membrane receptor field," stated Prof. Pierre De Meyts, a renowned researcher of insulin and receptor binding for almost half a century and one of the reviewers of the paper by Prof. Ichiro Maruyama, the head of the Information Processing Biology Unit at Okinawa Institute of Science and Technology Graduate University (OIST).

A novel and affordable diagnostic test for chikungunya will soon be available thanks to the work of researchers at the University of Texas Medical Branch at Galveston in partnership with a commercial lab.

Chikungunya, a mosquito-borne illness that while not often deadly causes severe, incapacitating and often chronic joint pain, is spreading throughout the Americas. It can be difficult to diagnose and most tests available now are expensive and challenging to develop.

A recent study conducted by The University of Texas Medical Branch at Galveston shows that severely obese women who maintained or lost weight during pregnancy had healthier babies and lower health care costs.
