Reduced energy density in foods can create healthier food environment, may help to reduce obesity

Reduced energy density in foods can create healthier food environment, may help to reduce obesity

On the heels of new research showing that 16 major food and beverage companies have collectively cut 6.4 trillion calories from U.S. food products, The Obesity Society (TOS) issues an official position statement pointing to the pervasive availability of foods high in calories per unit of weight, or energy density, as a contributing factor for weight gain and obesity. The Society goes further to urge food companies to test and market foods that will help individuals reduce the energy density in their diets and better manage body weight. Continue reading

Environmental costs, health risks, and benefits of fracking examined

Environmental costs, health risks, and benefits of fracking examined

A strange thing happened on the way to dealing with climate change: Advances in hydraulic fracturing put trillions of dollars’ worth of previously unreachable oil and natural gas within humanity’s grasp. The environmental costs — and benefits — from “fracking,” which requires blasting huge amounts of water, sand and chemicals deep into underground rock formations, are the subject of new research that synthesizes 165 academic studies and government databases. The survey covers not only greenhouse gas impacts but also fracking’s influence on local air pollution, earthquakes and, especially, supplies of clean water Continue reading

Cancer patients: How strongly does tissue decelerate the therapeutic heavy ion beam?

Cancer patients: How strongly does tissue decelerate the therapeutic heavy ion beam?

Irradiation with heavy ions is suitable in particular for patients suffering from cancer with tumours which are difficult to access, for example in the brain. These particles hardly damage the penetrated tissue, but can be used in such a way that they deliver their maximum energy only directly at the target: the tumour. Research in this relatively new therapy method is focussed again and again on the exact dosing: how must the radiation parameters be set in order to destroy the cancerous cells “on the spot” with as low a damage as possible to the surrounding tissue?

Cure for dry eye could be a blink away

Cure for dry eye could be a blink away

A treatment for dry eye — a burning, gritty condition that can impair vision and damage the cornea — could some day result from computer simulations that map the way tears move across the surface of the eye. Kara Maki, assistant professor in Rochester Institute of Technology’s School of Mathematical Sciences, contributed to a recent National Science Foundation study seeking to understand the basic motion of tear film traversing the eye Continue reading

A new study published today in Obesity , the journal of The Obesity Society, confirms that drinking diet beverages can help people lose weight. Continue reading

New neural pathway found in eyes that aids in vision

New neural pathway found in eyes that aids in vision

A type of retina cell plays a more critical role in vision than previously known, a team led by Johns Hopkins University researchers has discovered. Working with mice, the scientists found that the ipRGCs — an atypical type of photoreceptor in the retina — help detect contrast between light and dark, a crucial element in the formation of visual images. The key to the discovery is the fact that the cells express melanopsin, a type of photopigment that undergoes a chemical change when it absorbs light Continue reading

Living conditions in Iraq must improve if investment in health system is to yield results

Living conditions in Iraq must improve if investment in health system is to yield results

Despite enormous investment in Iraq’s health system in the 10 years since the US-led invasion, the health condition of Iraqis has deteriorated and will fail to improve unless more is done to improve living conditions. A review published today in the Journal of the Royal Society of Medicine concludes that continual investment in health services is crucial to elevate the health status of the Iraqi population, but that progress will be limited without improvements in housing, water and sanitation, electricity, transport, agriculture, education and employment Continue reading

Cause of many preterm births discovered: Premature aging of placenta from oxidative stress

Cause of many preterm births discovered: Premature aging of placenta from oxidative stress

A new study by researchers at the University of Texas Medical Branch at Galveston is the first to show that premature aging of the placenta due to oxidative stress is the cause of many preterm births. The study appears today in the American Journal of Pathology. Continue reading
