CHAPEL HILL - A group of University of North Carolina Lineberger Comprehensive Cancer Center researchers is calling for an overhaul of the process that determines which cancer drugs used off-label -- or beyond their approved use -- are reimbursed by federally-funded health insurance in the United States.

PHILADELPHIA - A new biomaterial can be used to study how and when stem cells sense the mechanics of their surrounding environment, found a team led by Robert Mauck, PhD, the Mary Black Ralston Professor for Education and Research in Orthopaedic Surgery, in the Perelman School of Medicine at the University of Pennsylvania. With further development, this biomaterial could be used to control when immature stem cells differentiate into more specialized cells for regenerative and tissue-engineering-based therapies.
Google "telecommuting" and you'll find business articles like:
"Four reasons why telecommuting is bad for business" or: "Is telecommuting an effective way to work" and, of course: "Four reasons telecommuting is good for employees"
Clearly, the jury is still out on the practice. Some companies do it, some don't. Others, like Yahoo, used to do it but have now said no more.
Scientists have identified a new "multicomponent" virus -- one containing different segments of genetic material in separate particles -- that can infect animals, according to research published today in the journal Cell Host & Microbe.
Can the woolly mammoth be brought back from the dead? Scientists say it's only a matter of time.
In fact this year, the International Union for Conservation of Nature issued its first official set of guidelines on resurrecting extinct species. What's more, university research labs and non-governmental agencies have projects in motion to bring back extinct species. But is all of this a good idea?
Scientists have discovered an alternative way to create a stronger binding between pharmaceutical drugs and the part of the body they are targeting - a development that can be used to fight a variety of diseases, including breast cancer. The study published in PLOS Computational Biology shows that flexible molecules, instead of rigid ones, as previously thought, can bind more effectively to the proteins causing the disease.
BOSTON - (August 25, 2016) - Diabetes heightens the risk of vascular damage to heart and limbs, and impairs the ability to repair damage with new growth of blood vessels, called angiogenesis. There are no established drugs to improve angiogenesis in diabetes. However, researchers at Joslin Diabetes Center now have identified a gene called CITED2 in a molecular pathway that may offer targets for drugs that treat these conditions by strengthening angiogenesis.
COLUMBIA, Mo. - More than 15 million Americans live within a one-mile radius of unconventional oil and gas (UOG) operations. UOGs combine directional drilling and hydraulic fracturing, or "fracking," to release natural gas from underground rock. Scientific studies, while ongoing, are still inconclusive on the potential long-term effects fracturing has on human development.
WHAT:
PHOENIX - Researchers at Barrow Neurological Institute have traced the roots of humane medical practices to a pioneering French physician who treated people with deformities as humans instead of "monsters," as they were commonly called.
CAMBRIDGE, Mass. -- A new device developed by researchers at MIT and a physician at Connecticut Children's Medical Center could greatly improve doctors' ability to accurately diagnose ear infections. That could drastically reduce the estimated 2 million cases per year in the United States where such infections are incorrectly diagnosed and unnecessary antibiotics are prescribed. Such overprescriptions are considered a major cause of antibiotic resistance.
Human noroviruses - the leading viral cause of acute diarrhea around the world - have been difficult to study because scientists had not found a way to grow them in the lab. Now, more than 40 years after Dr. Albert Kapikian identified human noroviruses as a cause of severe diarrhea, scientists at Baylor College of Medicine have, for the first time, succeeded at growing noroviruses in laboratory cultures of human intestinal epithelial cells.
Despite years of research, cellular mechanisms contributing to cancers like esophageal adenocarcinoma have remained elusive. What has puzzled researchers was how genes in the healthy cells lining the esophagus turned the normal cells into malignant ones. Now, researchers from Case Western Reserve University School of Medicine have characterized structurally abnormal genes in esophageal adenocarcinoma, the findings of which could pave way for developing new biomarkers in this fatal disease.
Researchers from the RAND Corporation and the Lawrence Livermore National Laboratory have joined forces to combine high-performance computing with innovative public policy analysis to improve planning for particularly complex issues such as water resource management.
In 1963, Irish surgeon Denis Parson Burkitt airmailed samples of an unusual jaw tumor found in Ugandan children to his colleague, Anthony Epstein, at Middlesex Hospital in London. Epstein, an expert in chicken viruses and an early adopter of the electron microscope, cultured the tissue and took a look. What he found has become known as Epstein-Barr virus, the cause of mononucleosis, the "kissing cold", and also, it turns out, an ingredient of the jaw tumor in which it was originally found, now known as Burkitt's lymphoma.
