It's not just American cars that are hurting the environment, researchers in California and Colorado have set their sights on ... rocket launches?
Future ozone losses from unregulated rocket launches will eventually exceed ozone losses due to chlorofluorocarbons, or CFCs, which stimulated the 1987 Montreal Protocol banning ozone-depleting chemicals, said Martin Ross, chief study author from The Aerospace Corporation in Los Angeles. The study, which includes the University of Colorado at Boulder and Embry-Riddle Aeronautical University, provides a market analysis for estimating future ozone layer depletion based on the expected growth of the space industry and known impacts of rocket launches.

Here's another reason to hate leftovers. A research study in the Journal of Leukocyte Biology sheds light on one cause of arthritis: bacteria. In the study, scientists from the United States and The Netherlands show that a specific gene called NOD2 triggers arthritis or makes it worse when leftover remnants of bacteria cell walls, called muramyl dipeptide or MDP, are present. This discovery offers an important first step toward new treatments to prevent or lessen the symptoms of inflammatory arthritis.

Here's another reason why dieters should avoid all-you-can-eat buffets: When faced with a large variety of items, consumers tend to underestimate how much of each item is present, according to a new study in the Journal of Consumer Research.Authors Joseph P. Redden (University of Minnesota) and Stephen J. Hoch (University of Pennsylvania) investigated consumers' perceptions of quantity in a set of experiments that may help us understand how quantity perceptions influence portion sizes."Does a bowl with both red and blue candies seem to have more or less than a bowl with only one color candy?" the researchers asked. "Contrary to popular belief, the presence of variety actually makes it seem like there are fewer items."

Some consumers will opt for local products and others always prefer global brands.   A new study in the Journal of Consumer Research takes a look at why local goods can even beat out recognizable global brands like Coke or Pepsi."Due to rapid globalization, local products—products with specifications and packaging tailored for local markets, such as Mecca Cola (France) and Fei-Chang Cola (China)—and global products (products with the same specifications and packaging for consumers from around the world) such as Pepsi and Coke, routinely compete against each other," write authors Yinlong Zhang (University of Texas at San Antonio) and Adwait Khare (Quinnipiac University).

It has been revealed that 1 in 3 people in the UK are still struggling to find an NHS dentist, according to new research from Simplyhealth.
Simplyhealth's Annual Dental Survey has revealed that alarmingly just over a third of Brits (35%) struggled to find an NHS dentist over the last year, which has increased from 23% at the same time in 2008.
Perhaps more shocking is the fact that this figure soars in certain areas of the UK, with over half of the people in Plymouth finding it difficult to get an NHS dentist, closely followed by those in Southampton and Manchester, where 45% and 43% have struggled.
The severity of the situation this year has been heightened by the economic downturn, as almost half of people across the UK have put off visiting the dentist becaus

Researchers at the universities of Leicester and Oxford have made a discovery about plant growth which could potentially have an enormous impact on crop production as global warming increases.Dr Kerry Franklin, from the University of Leicester Department of Biology led the study which has identified a single gene responsible for controlling plant growth responses to elevated temperature.

Video games that involve high levels of action,like first-person-shooter games, can increase real-world vision, according to research in Nature Neuroscience, including discerning slight differences in shades of gray; an attribute of the human visual system that can't be improved, it has been believed. Daphne Bavelier, professor of brain and cognitive sciences at the University of Rochester, says that very practiced action gamers can actually become 58 percent better at perceiving fine differences in contrast.

Individuals with autism spectrum disorders (ASD) tend to stare at people's mouths rather than their eyes. A new study of 2-year-olds with the social deficit disorder suggests why they might find mouths so attractive: lip-sync—the exact match of lip motion and speech sound. Such audiovisual synchrony preoccupied toddlers who have autism, while their unaffected peers focused on socially meaningful movements of the human body, such as gestures and facial expressions. 

Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed. The researchers use stiff stilbene, a small, inert structure, as a molecular force probe to generate well-defined forces on various molecules, atom by atom. "By pulling on different pairs of atoms, we can explore what happens when we stretch a molecule in different ways," said chemistry professor Roman Boulatov. "That information tells us a lot about the properties of fleeting structures called transition states that govern how, and how fast, chemical transformations occur." 

The benefits to animals of omega 3 fatty acids in fish oils have been well documented – helping the heart and circulatory system.   Can they also help in improving meat quality and reducing methane emissions?Perhaps.   Methane given off by farm animals is a major contributor to greenhouse gas levels and researchers from University College Dublin have reported that by including 2% fish oil in the diet of cattle they achieved a reduction in the amount of methane released by the animals.

While physical exercise has been shown to trigger migraine headaches among sufferers, a new study describes an exercise program that is well tolerated by patients. The findings show that the program decreased the frequency of headaches and improved quality of life. The study is published in Headache: The Journal of Head and Face Pain.
The study used a sample of migraine sufferers who were examined before, during and after an aerobic exercise intervention. The program was based on indoor cycling (for continuous aerobic exercise) and was designed to improve maximal oxygen uptake without worsening the patients' migraines.

Chemists reported development of what they termed the first economical, eco-friendly process to convert algae oil into biodiesel fuel — a discovery they predict could one day lead to U.S. independence from petroleum as a fuel.One of the problems with current methods for producing biodiesel from algae oil is the processing cost, and the New York researchers say their innovative process is at least 40 percent cheaper than that of others now being used. Supply will not be a problem: There is a limitless amount of algae growing in oceans, lakes, and rivers, throughout the world.Another benefit from the "continuously flowing fixed-bed" method to create algae biodiesel, they add, is that there is no wastewater produced to cause pollution.
