Stroke patients with obstructive sleep apnea (OSA) who undergo treatment with continuous positive airway pressure (CPAP) following their stroke may substantially reduce their risk of death, according to Spanish research to be published in the July 1 issue of the American Journal of Respiratory and Critical Care Medicine.

In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory. Scientists have long believed that other, similar vesicles handle the reverse function, importing life-supporting nutrients and proteins through an independent process.

COLLEGE PARK, M.D.. June 25 –– Fast and green. That's what it takes to get to the winner's circle in a new type of auto racing.

Called green racing, it's a meshing of the fast and furious world of auto racing with the quest for cleaner-burning fuels and more energy efficient engines. But make no mistake about it, being green does not mean being slow.

John C. Glenn, an environmental specialist with the U.S. Environmental Protection Agency (EPA), described green racing here today at the 13th Annual ACS Green Chemistry & Engineering Conference.

Baltimore, MD—Scientists working at the Carnegie Institution's Department of Embryology, with colleagues, have overturned previous research that identified critical genes for making muscle stem cells. It turns out that the genes that make muscle stem cells in the embryo are surprisingly not needed in adult muscle stem cells to regenerate muscles after injury. The finding challenges the current course of research into muscular dystrophy, muscle injury, and regenerative medicine, which uses stem cells for healing tissues, and it favours using age-matched stem cells for therapy.

Baltimore, MD, and Christchurch, NZ – June 25, 2009 – Veritide Ltd., a developer of innovative biological identification and detection solutions, today reported that new independent data to be presented at the Biodetection Technologies 2009 conference confirm the exceptional accuracy of its Ceeker™ (pronounced "seeker") portable bacterial detection device in discriminating between anthrax spores and similar-looking hoax substances.

Cincinnati, OH, June 25, 2009 -- Many parents worry about their child's exposure to phthalates, the chemical compounds used as plasticizers in a wide variety of personal care products, children's toys, and medical devices. Phthalate exposure can begin in the womb and has been associated with negative changes in endocrine function. A new study soon to be published in the Journal of Pediatrics examines the possibility that in utero phthalate exposure contributes to low birth weight in infants.

In addition to providing fundamental insights into the early evolution of the estrogen receptor, research by a team at the University of California, San Diego School of Medicine may lead to a contraceptive for female lampreys – a jawless fish considered an invasive pest species in the Great Lakes region of the United States. This could prove important to the Great Lakes region, where lampreys aggressively consume trout, salmon, sturgeon and other game fish.

Researchers at the University of California, San Francisco Center for Excellence in Primary Care, as lead authors on commentaries in two of the nation's leading medical journals this week, call for a national effort to revive primary care as part of health care reform legislation.

CHAMPAIGN, Ill. – A team of researchers at the University of Illinois has created the world's first acoustic "superlens," an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology.

ATLANTA—June 24, 2009—A new study suggests that a drop in colorectal cancer incidence seen nationwide has not occurred among people living in poorer communities, and suggests that barriers to health care may be to blame. The study appears online in the journal Cancer Causes and Control.
