Oceanographers examine mercury levels of pelagic fish in Hawaii
Over time, an invasive plant loses its toxic edge
In the open ocean, species of large predatory fish will swim and hunt for food at various depths, which leads to unique diets in these fish. Oceanographers and geologists in the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaiʻi at Mānoa (UHM) and colleagues have found that those fish that hunt deeper in the open ocean have higher mercury concentrations...
Scientists find genetic marker associated with ovarian cancer risk
Like most invasive plants introduced to the U.S. from Europe and other places, garlic mustard first found it easy to dominate the natives. A new study indicates that eventually, however, its primary weapon - a fungus-killing toxin injected into the soil - becomes less potent.
Some discrepancies exist between outcomes indicated in trial registration and later publications
A new genetic marker associated with ovarian cancer risk was recently discovered by an international research group, led by scientists from the Cancer Research Genetic Epidemiology Unit in the United Kingdom. Drs. Marc Goodman, Galina Lurie, Michael Carney, and Keith Terada of the University of Hawai'i at Mānoa's Cancer Research Center of Hawai'i participated in the validation of the...
Spacewalkers tackle hefty tank removal in space
Comparison of the primary outcomes of registered clinical trials with their subsequent publication appears to show some discrepancies, according to a study in the September 2 issue of JAMA.
Sugar cane to return to Angola in biofuel move
(AP) -- A pair of spacewalkers tackled a hefty tank removal job at the international space station Tuesday as their crewmates unloaded comedian Stephen Colbert's namesake treadmill for all "those famously fat astronauts."
The 'S' stands for surprise: Anticoagulant plays unexpected role in maintaining circulatory integrity
Angola will begin planting sugar cane for the first time in more than 30 years this month as the oil-rich country takes its first step toward biofuels.
US appeals court nixes Internet gambling challenge
Protein S, a well-known anticoagulant protein, keeps the blood flowing in more than one way, discovered researchers at the Salk Institute for Biological Studies. The protein contributes to the formation and function of healthy blood vessels.

NASA's New Moonship Passes Review Amid Rocket Uncertainty
A new study claims to have found the original date and birthplace of the first dogs.
Caring for the whole person -- using systems medicine
SPACE.com - NASA's new
spaceship intended to send astronauts into space and ultimately the moon has
passed an early design review amid uncertainty over whether the rocket slated
to launch it into orbit will ever fly.
Computational process zeroes in on top genetic cancer suspects
At a time when medicine tends to focus on patients as a "collection of visceral organs and a nervous system," systems medicine provides a new approach to medical practice that is "anticipated to result in more comprehensive and systematic patient care." In a commentary published today in the Journal of the American Medical Association (Sept 2), Howard J. Federoff, MD, PhD, executive vice...
Distribution of antibiotic for eye disease linked to low death risk among Ethiopian children
Johns Hopkins engineers have devised innovative computer software that can sift through hundreds of genetic mutations and highlight the DNA changes that are most likely to promote cancer. The goal is to provide critical help to researchers who are poring over numerous newly discovered gene mutations, many of which are harmless or have no connection to cancer. According to its inventors, the new...
Exercise alone shown to improve insulin sensitivity in obese sedentary adolescents
Children in Ethiopia who received the antibiotic azithromycin as a method for controlling the contagious eye disease trachoma had a lower odds of death compared to children who did not receive the antibiotic, according to a study in the September 2 issue of JAMA.
Getting better visualization of joint cartilage through cationic CT contrast agents
A moderate aerobic exercise program, without weight loss, can improve insulin sensitivity in both lean and obese sedentary adolescents, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Insulin is a hormone produced in the pancreas that permits glucose to enter cells to be used for energy or stored for future use by...
Gmail knocked offline for 'majority' of users
In its quest to find new strategies to treat osteoarthritis and other diseases, a Boston University-led research team has reported finding a new computer tomography contrast agent for visualizing the special distributions of glycosaminoglycans (GAGs) - the anionic sugars that account for the strength of joint cartilage.
Immediate intervention for patients with ACS not always more beneficial
(AP) -- Google Inc.'s Gmail service was knocked offline Tuesday in a severe outage that the company said affected a "majority" of users.
New information about how fat increases blood pressure could help identify those at risk
For some patients with acute coronary syndromes, the strategy of immediate intervention at a medical center does not appear to result in differences in outcomes in comparison with an intervention performed the next working day, according to a study in the September 2 issue of JAMA.
New report describes types of research conducted at academic medical centers
Some of the first information about how fat causes hypertension have been identified by researchers who say the findings should one day help identify which obese people - and maybe some thin ones too - are at risk for hypertension and which drugs would work best for them.
New study compares after-hours and daytime surgery success rates
A study from the Massachusetts General Hospital (MGH) Institute for Health Policy gives the first detailed look at the types of research currently being conducted within U.S. academic medical centers - medical schools and their affiliated hospitals. The report in the Sept. 2 Journal of the American Medical Association describes how the traditional way of categorizing life-science researchers as...
Researchers use newborn blood data to study cerebral palsy
Patients who have after-hour orthopaedic surgeries risk a slightly higher rate of necessary follow-up surgeries, according to a study published in the September 2009 issue of The Journal of Bone and Joint Surgery (JBJS). The data also suggests that patients whose surgeries took place during the day have the same healing, recovery time, and major complication rates as patients who have surgery...
Study finds Web no equalizer for civic engagement
A statewide team of researchers led by a Michigan State University epidemiologist are hoping Michigan's archive of newborn blood spots will help them uncover the causes of cerebral palsy, the most common disabling motor disorder in children with annual health costs of $12 billion.
(AP) -- Unlike some people have hoped, the Internet hasn't led to big changes in the socio-economic makeup of Americans engaged in civic activities, a new study from the Pew Internet and American Life Project finds.
