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.
The use of asbestos continues to increase in Asia despite clear health hazards. A recent Respirology review notes that with approximately 4.3 billion people and a growing population, Asia will likely see a large crop of asbestos-related lung diseases in the next few decades. Some of the cases will be benign, but it is likely that there will be many cases of mesothelioma and lung cancer.
Efforts are needed to improve the recognition and diagnosis of asbestos-related lung diseases, and government and non-government groups must cooperate to take steps to prevent them.

A broccoli variety modified to have two to three times more of the naturally occurring compound glucoraphanin, which is linked to antioxidants and other health benefits, also reduces blood LDL-cholesterol levels by around 6%, according to results of human trials. Glucoraphanin is thought to work by helping maintain cellular metabolism. Mitochondria, the energy factories of the cell, convert sugars and fats into energy, but if they aren't working efficiently, one response is to channel excess into cholesterol.
Light is a useful tool for quantum communication, but it has one major disadvantage - it travels at the speed of light and sometimes things need to be kept in place, or at least slowed down. Like with trains all sharing a track, you can't have one express line with no brakes for very long. A team researchers has demonstrated they can put the brakes on light, and not in some arcane quantum system but rather in glass fiber networks we are already using today. By coupling atoms to glass fibers light was slowed down to train speed - 90 miles per hour - and they even managed to bring the light to a complete stop and to retrieve it again later.
Life has adapted to all sorts of extreme environments on Earth, among them, animals like the deer mouse, shimmying and shivering about, and having to squeeze enough energy from the cold, thin air to fuel their bodies and survive.
In a new paper, Scott, Cheviron et al., have examined the underlying muscle physiology from a group of highland and lowland deer mice. Peromyscus maniculatus - deer mice - were chosen because they exhibit the most extreme altitude range of any North American mammal, occurring below sea levels in Death Valley to more than 4,300 meters high in the mountains.
Researchers have taken a step toward using the implantation of stem cell-generated neurons as a treatment for Parkinson's disease.
Parkinson's, which affect as many 10 million people in the world, is linked to a depletion of dopamine-producing neurons in the brain. Current treatments include medications and electrical implants in the brain which cause severe adverse effects over time and fail to prevent disease progression. Several studies have indicated that the transplantation of embryonic stem cells improves motor functions in animal models but the procedure has shown to be unsafe, because of the risk of tumors upon transplantation.
Clearing grasslands to make way for biofuels may seem counterproductive, but University of Wisconsin-Madison researchers show in a study today (April 2, 2015) that crops, including the corn and soy commonly used for biofuels, expanded onto 7 million acres of new land in the U.S. over a recent four-year period, replacing millions of acres of grasslands.
Is there any point to the World Health Organization (WHO) making a recommendation that 3 people out of 1,000 can achieve? If not, Americans won't take WHO seriously, and the British respect those guidelines even less. Only 1 in 1,000 in the UK can meet WHO's targets for potassium and sodium.The World Health Organization recommends we consume no more than 2,000 mg of sodium a day - less than a teaspoon of salt - supposedly because of studies showing it impacts heart disease and stroke. And they recommend at least 3,510 mg of potassium daily, again to lower our odds of heart disease and stroke.
A new study of 311 childless Danish women initiating assisted reproduction using donor semen finds that single women seeking treatment are no different than cohabiting women seeking treatment when it comes to sociodemographic characteristics or attitudes toward motherhoodThe authors used baseline data collection in a multicenter cohort study from alll nine public fertility clinics in Denmark to examine sociodemographic characteristics, family backgrounds, reproductive histories, and attitudes towards motherhood in single vs. cohabiting women seeking treatment with donor semen.
If you ever thought your spouse makes your blood pressure go up, you now have a study to show it.Sociological and epidemiological papers have long linked stress and negative marital quality to changes in mortality and blood pressure but there has not been much to show how those correlate to married couples over time. Using systolic blood pressure as a gauge, researchers assessed whether an individual’s blood pressure is influenced by their own as well as their partner’s reports of chronic stress and whether there are gender differences in these patterns.
Japan is famous for committing suicide - as many people kill themselves using rope as Americans, with a much larger population, do with guns - but they may have more accurate numbers than western countries, according to a new paper. In western countries, suicide or accident is determined by a coroner. When it's a drug overdose versus a suicide is subjective, only guns are sure to be consistently implicated in a suicide, because gun control is part of a control war, where no one is quite sure what to make of drugs.
A new paper links eating disorders in adolescent females with lower levels of educational attainment and personal income in early adulthood. They were also less likely to own a home.
Osteoporosis is a medical condition characterized by bones becoming brittle and fragile. Age-related loss in muscle mass and strength is considered analogous to osteoporosis but this “sarcopenia” is not recognized as a clinical condition even though it is linked to impaired physical function and contribute to disability, falls, and hospitalizations. Lower muscle mass and strength are also associated with lower bone mineral density and greater risk for osteoporotic fractures.Why isn't sarcopenia
more accepted? No valid diagnostic criteria whereas osteoporosis can be diagnosed based on widely accepted clinical standards.
