After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
Using ESA’s Rosetta spacecraft, scientists have identified more than a hundred patches of water ice a few meters in size on the surface of Comet 67P/Churyumov-Gerasimenko. Rosetta arrived at the comet in August 2014 at a distance of about 100 kilometers and eventually orbited the comet at 10 kilometers or less, allowing high-resolution images of the surface to be acquired.
A new paper discusses the current barriers which limit opportunities to own a pet among older adults, going into detail about physical and financial risks for older adult pet ownership and how it can be diminished.Medical problems that arise with older adults, such as physical illness and emotional issues, have the potential to be mitigated by companionship of pets because it reduces social isolation and enhances physical activity. But illnesses that are often associated with aging, ranging from arthritis to diabetes, make it hard or impossible for older adults to provide routine care for their pets. Financial barriers are another issue that older pet owners face.
New research published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, reports that younger patients, those who are married, and those with Child-Pugh C disease—the most severe measure of liver disease—are more likely immigrants, divorced patients and those at the lowest income levels were less likely to have a potential live donor volunteer for liver donation.
21 states have opted not to expand Medicaid under the Affordable Care Act (ACA), arguing that the expansion would be too expensive. And since California had to convince taxpayers with a state government mandate to remain revenue neutral on the program, based on promises by Democrats in Washington, D.C., and are looking at an $80 million deficit the moment Federal subsidies expire, it seems like those 21 states are right.
But economists at Northwestern University and Columbia University’s Mailman School of Public Health argue that the cost to hospitals from uncompensated care in those states roughly equals the cost of Medicaid expansion.
Nitric oxide (NO) is a highly stable molecule that is also highly reactive and a free radical, meaning a single, unpaired electron is present in its molecule. NO plays the role of a mediator between elements and helps them combine. Radicals are regularly generated in many metabolic pathways. Some of these radicals can exist in a free form and subsequently interact with various tissue components resulting in dysfunction.
The land planarian Platydemus manokwari, or New Guinea flatworm, is a highly invasive species, already reported in many territories in the Pacific area, and as well as in France. This is the only land planarian in the '100 worst invasive alien species' list and it has now been found in additional localities including islands in the Pacific area, Puerto Rico, the first record in the Caribbean, and the first report in mainland U.S., in Florida.
We can use lightning rods to increase the probability of it striking at a specific location but its exact path remains unpredictable.
Perhaps not for long. At a smaller scale, discharges between two electrodes behave in the same manner, streaking through space to create electric arcs where only the start and end points are fixed. Knowing that, it may be possible to control the current so that it follows a predetermined path, say Professor Roberto Morandotti and colleagues from

who have discovered a way to guide electric discharges - and even steer them around obstacles - using lasers at the Advanced Laser Light Source (ALLS) facility.
A rigorous analysis of more than 20,000 medical records concludes that erectile dysfunction drugs, such as Viagra, are not a cause of melanoma, an often deadly form of skin cancer, despite the higher risk for the disease among users of these drugs.
The analysis, led by researchers at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center, of medical records for some 20,235 mostly white men suggests instead that the likely source of the observed uptick in malignant melanoma risk among users of erectile dysfunction drugs is socioeconomic and lifestyle based.
Renewable energy targets mandates and subsidies now in place in 164 countries powered the growth of solar, wind and other green technologies to record-breaking energy generation capacity in 2014. So to advocates that means CO2 emissions and growth do not have to go hand-in-hand. To critics, the fact that these alternative energy schemes only work when there are mandates and subsidies means fossil fuels should be cleaner, not eliminated.
According to REN21's latest Renewables Global Status Report, policymakers continued to focus on adapting existing policies to keep pace with rapidly changing costs and circumstances.
Men with an elevated, genetically inherited risk for prostate cancer could be routinely identified with a simple blood or urine test, scientists at UC San Francisco and Kaiser Permanente Northern California have concluded, potentially paving the way to better or earlier diagnosis.
The study, which compared 7,783 men with prostate cancer to 38,595 men without the disease, is available online and will be published in an upcoming issue of the journal Cancer Discovery.
An international team of scientists has found some of the best evidence yet that Venus, Earth's nearest neighbor, is volcanically active.
In combing through data from the European Space Agency's Venus Express mission, the scientists found transient spikes in temperature at several spots on the planet's surface. The hotspots, which were found to flash and fade over the course of just a few days, appear to be generated by active flows of lava on the surface.
"We were able to show strong evidence that Venus is volcanically, and thus internally, active today," said James W. Head, a geologist at Brown University and co-author of a paper describing the new research. "This is a major finding that helps us understand the evolution of planets like our own."
High in the sky where the cirrus ice crystal clouds form, jet contrails draw their crisscross patterns. Now researchers have found that these elevated ice cloud trails can influence temperatures on the ground and affect local climate.
For contrails to form, the atmosphere at the level the jet is flying must be cold enough that the moisture from the jet exhaust freezes into ice crystals. There also must be enough moisture in the air that the clouds that form remain in the sky for at least a few hours as persisting contrails.
