Over the last decade, energy drinks like such as Red Bull, Monster and Rockstar have become nearly popular on college campuses. The global market for these types of drinks currently exceeds $3 billion a year and new products are introduced annually.
Although research on the effect of energy drink consumption remains sparse, a researcher at the University at Buffalo's Research Institute on Addictions (RIA) says there are links between energy drinks and public health concerns like substance abuse and risky behaviors.
Two new research reports by RIA Research Scientist Kathleen E. Miller, Ph.D., examine the relationships between energy drink consumption and risk-taking in college students as well as "toxic jock identity" -- characterized by hyper-masculinity and risk-taking behaviors among college-age athletes.
Bring on the bad weather. A single typhoon in Taiwan buries as much carbon in the ocean (in the form of sediment) as all the other rains in that country all year long - combined.
The study published in Geology the first to examine the chemistry of stream water and sediments that were being washed out to sea while a typhoon was happening at full force. This new knowledhe should help scientists develop better models of global climate change.
Anne Carey, associate professor of earth sciences at Ohio State, said that she and her colleagues have braved two typhoons since starting the project in 2004. The Geology paper details their findings from a study of Taiwan's Choshui River during Typhoon Mindulle in July of that year.
Along with all the other changes that come with age, healthy older people also lose some capacity for sleep, according to a new report published online on July 24th in Current Biology, a Cell Press publication. When asked to stay in bed for 16 hours in the dark each day for several days, younger people get an average of 9 hours of shuteye compared to 7.5 for older people, the researchers report.
The study also found that most healthy people, and young people in particular, don't get as much sleep as they need.
The idea that sleep changes markedly across the life span isn't new. In fact, insomnia is a common complaint among older people. But whether age-related changes in sleep were due to changes in social factors, circadian rhythms, or shifts in an internal "set point" for sleep need or the ability to sleep had remained unresolved.
UC Irvine researchers have found a molecular link between circadian rhythms, our body clock, and metabolism. The discovery reveals new possibilities for the treatment of diabetes, obesity and other related diseases.
Circadian rhythms of 24 hours govern fundamental physiological functions in almost all organisms. The circadian clocks are intrinsic time-tracking systems in our bodies that anticipate environmental changes and adapt themselves to the appropriate time of day.
Disruption of these rhythms can profoundly influence human health and has been linked to metabolic disorders, insomnia, depression, coronary heart diseases and cancer.
One of the reasons people on low-carbohydrate diets may lose weight is that they reduce their intake of fructose, a type of sugar that can be made into body fat quickly, according to a researcher at UT Southwestern Medical Center.
Dr. Elizabeth Parks, associate professor of clinical nutrition and lead author of a study appearing in a current issue of the Journal of Nutrition, said her team's findings suggest that the right type of carbohydrates a person eats may be just as important in weight control as the number of calories a person eats.
Current health guidelines suggest that limiting processed carbohydrates, many of which contain high-fructose corn syrup, may help prevent weight gain, and the new data on fructose clearly support this recommendation.
Livestock manure, left to decompose naturally, emits two particularly potent greenhouse gas emissions (GHGs) – nitrous oxide and methane. According to the Intergovernmental Panel on Climate Change, nitrous oxide warms the atmosphere 310 times more than carbon dioxide, methane does so 21 times more.
Converting livestock manure into a domestic renewable fuel source could lead to a significant reduction in GHGs and generate enough electricity to meet up to three per cent of North America's entire consumption needs, according to research published in the Institute of Physics' Environmental Research Letters.
The paper, 'Cow Power: The Energy and Emissions Benefits of Converting Manure to Biogas', has implications for all countries with livestock as it is the first attempt to outline a procedure for quantifying the national amount of renewable energy that herds of cattle and other livestock can generate and the concomitant GHG emission reductions.
