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.
A recent study has revealed a breakthrough in asthma research might be on the horizon. Following extensive research carried out across a number of institutions, it has been discovered that protein molecules - known as calcium-sensing receptors - have a vital role in asthma. Although they have not previously been used to treat asthma, there is already medication available (calcilytics) that could be used to block these proteins.
In asthmatics, the immune system essentially misidentifies harmless substances, such as pollen for example, as a threat. The airways then restrict in an attempt to keep the ‘harmful’ substances from entering the lungs leading to the body facing constricted airways and, therefore, less ability to breathe properly.
About 2.5 billion people worldwide don't have access to sanitary toilets. Latrines are an option for many of those people, but these facilities' overwhelming odors can deter users, who then defecate outdoors instead. To improve this situation, fragrance scientists paired experts' noses and analytical instruments to determine the odor profiles of latrines with the aim of countering the offensive stench. Their report appears in the ACS journal Environmental Science & Technology.
A global-scale study has estimated how forest emitted compounds affecting cloud seeds via formation of low-volatility vapours. According to the latest projections, terrestrial vegetation emits several million tons of extremely low-volatility organic compounds (ELVOCs) per year to the atmosphere.
U.S. Congress members' social circles are more important in how they vote than their liberal or conservative beliefs or constituents' opinions, according to a new model of voting behavior created by Dartmouth College researchers.
The study appears in the journal Research & Politics. A PDF is available on request.
The standard model of voting behavior basically assumes there is only one factor that matters: where a legislator lives on the liberal-conservative axis. That position, derived from their roll call votes, serves as an ideological marker that presumably summarizes the various forces that can influence the legislators' votes, including personal preferences, party preferences and constituent opinion.
Giant strides have been taken in the early care of very premature infants in postnatal intensive care units during the past two decades. Doctors can now support the function of especially the lungs, heart and the circulatory system so as to guarantee the survival of most of even extremely premature infants.
Despite a good start, many of these may still have lifelong problems with brain function, such as attention deficit disorders or difficulty with visual function. For this reason, the primary focus of developing care for premature infants has been on securing brain development.
A Virgin Birth - parthenogenesis - may be a big deal in human culture but among wild sawfish in Florida it is apparently downright common. A new study finds that around 3 percent of the sawfish living in a Florida estuary are apparently the products of this type of reproduction, the first evidence of this in the wild for any vertebrate animal.
Researchers have observed a sudden increase of ice loss in a previously stable region of Antarctica. Using measurements of the elevation of the Antarctic ice sheet made by a suite of satellites, the researchers found that the Southern Antarctic Peninsula showed no signs of change up to 2009. Around 2009, multiple glaciers along a vast coastal expanse, measuring some 750 kilometers in length, suddenly started to shed ice into the ocean at a nearly constant rate of 60 cubic kilometers, or about 55 trillion liters of water, each year.
The room is loud with chatter. Glasses clink. Soft music, perhaps light jazz or strings, fills the air. Amidst all of these background sounds, it can be difficult to understand what an adjacent person is saying. A depressed individual, brought to this cocktail party by a well-meaning friend, can slide further into himself, his inability to hear and communicate compounding his sense of isolation.
"A lot of research has suggested that these people with elevated depression symptoms have a bias towards negative perception of information in this kind of environment," said Zilong Xie, a graduate student in the SoundBrain Lab in the Department of Communication Sciences and Disorders at the University of Texas at Austin.
Tropical rainforests have long been considered the Earth's lungs, sequestering large amounts of carbon dioxide from the atmosphere and thereby slowing down the increasing greenhouse effect and associated human-made climate change. Scientists in a global research project now show that the vast extensions of semi-arid landscapes occupying the transition zone between rainforest and desert dominate the ongoing increase in carbon sequestration by ecosystems globally, as well as large fluctuations between wet and dry years. This is a major rearrangement of planetary functions.
A new study shows that semi-arid ecosystems, savannahs and shrublands, play an extremely important role in controlling carbon sinks and the climate-mitigating ecosystem service they represent.
A new study found that esophageal cancer patients treated with proton therapy experienced significantly less toxic side effects than patients treated with older radiation therapies.
The researchers looked at nearly 600 patients and compared two kinds of X-ray radiation with proton therapy, which targets tumors while minimizing harm to surrounding tissues. found that proton therapy resulted in a significantly lower number of side effects, including nausea, blood abnormalities and loss of appetite.
Hallucinations and delusions in the general population are more common than previously thought, according to a study which found that hearing voices and seeing things others cannot impacts about five percent of the general population at some point in their lives.
Queensland Brain Institute researcher Professor John McGrath said the study, involving more than 31,000 people from 19 countries, was the most comprehensive ever completed.
Several genes have been lost from the Y chromosome in humans and other mammals but essential Y genes are rescued by relocating to other chromosomes, according to a new study.
The Y chromosome is dramatically smaller than the X chromosome and has already lost nearly all of the 640 genes it once shared with the X chromosome.
