Osteoporosis screening guidelines miss many younger post-menopausal women
(University of California - Los Angeles Health Sciences) To reduce the risk of bone fractures and associated complications, the United States Preventive Services Task force recommends that postmenopausal women aged 50 to 64 get bone mineral density screenings if their 10-year probability of suffering a is 9.3 percent or greater. But a new study finds that the United States Preventive Services Task force strategy predicted only slightly more than one-fourth of the women who went on to experience major osteoporotic fractures within 10 years.

UT Arlington researcher's device could detect vapors in environment or a person's breath
(University of Texas at Arlington) A University of Texas at Arlington researcher has received a three-year, $400,369 National Science Foundation grant to build a handheld device that could analyze a person's breath to reveal whether certain dangerous gasses are present that need more immediate medical attention.

UT Arlington to host international gathering of mind, brain and education experts
(University of Texas at Arlington) University of Texas at Arlington prepares for major role in international gathering of mind, brain and education experts.

When the isthmus is an island: Madison's hottest, and coldest, spots
(University of Wisconsin-Madison) In a new study published this month in the Journal of Applied Meteorology and Climatology, University of Wisconsin-Madison researchers highlight the urban heat island effect in Madison: the city's concentrated asphalt, brick and concrete lead to higher temperatures than its nonurban surroundings.

NC State researchers advance genome editing technique
(North Carolina State University) Customized genome editing -- the ability to edit desired DNA sequences to add, delete, activate or suppress specific genes -- has major potential for application in medicine, biotechnology, food and agriculture.Now, in a paper published in Molecular Cell, North Carolina State University researchers and colleagues examine six key molecular elements that help drive this genome editing system, which is known as CRISPR-Cas.

Case Western Reserve University School of Medicine dean, department chair elected to IOM
(Case Western Reserve University) Case Western Reserve University School of Medicine Dean Pamela B. Davis, MD, PhD, and Department of Physiology and Biophysics Chair Walter Boron, MD, PhD, have won election to the Institute of Medicine of the National Academies, one of the nation's most prestigious societies for health and medicine.

Preservation technique for marginal livers prevents biliary stricture
(Wiley) New research shows that a preservation technique known as sequential subnormothermic ex vivo liver perfusion (SNEVLP) prevents ischemic type biliary stricture following liver transplantation using grafts from donations after cardiac death (DCD). Findings published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, indicate that the preservation of DCD grafts using SNEVLP versus cold storage reduces bile duct and endothelial cell injury post transplantation.

UNH hosts oil spill response forum Oct. 28-29
(University of New Hampshire) It's been 25 years since the Exxon Valdez spilled 11 million gallons of crude oil into Prince William Sound, and nearly five years since the explosion of the Deepwater Horizon oil rig in the Gulf of Mexico gushed 200 million gallons of crude oil. On Oct. 28-29, 2014, nearly 40 experts and eyewitnesses from science, government, industry and NGOs will gather to look back -- and forward -- at oil spill response.

Resetting the circadian clock: Shift workers might want to skip high-iron foods
(University of Utah Health Sciences) A study sheds light on higher incidence of metabolic diseases among those who work off-hours.

Kung fu stegosaur
(Geological Society of America) Stegosaurs might be portrayed as lumbering plant eaters, but they were lethal fighters when necessary, according to paleontologists who have uncovered new evidence of a casualty of stegosaurian combat. The evidence is a fatal stab wound in the pubis bone of a predatory allosaur. The wound -- in the conical shape of a stegosaur tail spike -- would have required great dexterity to inflict and shows clear signs of having cut short the allosaur's life.
