Craigslist's entry into a market results in a 15.9 percent increase in reported HIV cases, according to research from the University of Minnesota published in the December issue of MIS Quarterly.
Researchers revamp a common 'data structure' so that it will work with multicore chips.
The discoveries, in Clark County in southern Nevada and across the border in northwestern Arizona, suggest that asbestos may be more widespread than previously thought; they also raise questions about the potential health hazards of naturally occurring asbestos.
The close of the Permian Period around 250 million years ago saw Earth's biggest extinction ever. At this time large volcanic eruptions were occurring in what is now Siberia. The volcanoes pumped out gases that led to acid rain. Falling on the supercontinent Pangaea, the acid rain killed off end-Permian forests. The demise of forests led to soil erosion and the production of organic-rich sediments in shallow marine waters.
Alex John London and Yael Schenker question the impact of health information that is available online, specifically hospital advertisements. London and Schenker argue that while the Internet offers patients valuable data and tools -- including hospital quality ratings and professional treatment guidelines - that may help them when facing decisions about where to seek care or whether to undergo a medical procedure, reliable and unbiased information may be hard to identify among the growing number of medical care advertisements online.
In a finding vital to effective species management, a team including City College of New York biologists has determined that the lined seahorse (Hippocampus erectus) is more a permanent resident of the western mid-Atlantic Ocean than a vagrant.
Two new fluorescent dyes attracted to cancer cells may help neurosurgeons more accurately localize and completely resect brain tumors, suggests a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
More than three-fourths US neurosurgeons practice some form of defensive medicine -- performing additional tests and procedures out of fear of malpractice lawsuits, reports a special article in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
'Bio-molecular interaction analysis, a cornerstone of biomedical research, is traditionally accomplished using equipment that can cost hundreds of thousands of dollars,' said Wyss Associate Faculty member Wesley P. Wong, Ph.D., senior author of study. 'Rather than develop a new instrument, we've created a nanoscale tool made from strands of DNA that can detect and report how molecules behave, enabling biological measurements to be made by almost anyone, using only common and inexpensive laboratory reagents.'
Mobile devices are everywhere and children are using them more frequently at young ages. The impact these mobile devices are having on the development and behavior of children is still relatively unknown. In a commentary in the journal Pediatrics, researchers review the many types of interactive media available today and raise important questions regarding their use as educational tools, as well as their potential detrimental role in stunting the development of important tools for self-regulation.
