A new study demonstrates that ambient temperatures can influence the growth or loss of brown fat in people. Cool environments stimulate growth, warm environments loss. The study results clearly show the 'plasticity' of brown fat in humans. Brown fat, also known as brown adipose tissue, is a special kind of fat that burns energy to generate heat. It keeps smallRead more

Iranian researchers from Isfahan University of Technology in association with researchers from Singapore National University produced nanofibers for the treatment of surface and deep wounds. The nanofibers are made of cheap and available materials and they are able to control humidity and oxygen diffusion into the wound. Delivery of nutritious materials to cells and removing the wastes are among otherRead more

Never stop learning. That's the takeaway from a new study that suggests a lifetime of feeding the brain new information can delay the onset of dementia by up to nine years. That staying mentally active helps keep dementia and Alzheimer's at bay isn't entirely new wisdom; it's been a refrain of both expert and amateur health advocates for years. ButRead more

People who live in neighborhoods that are conducive to walking experienced a substantially lower rate of obesity, overweight and diabetes than those who lived in more auto-dependent neighborhoods, according to a pair of studies. Researchers in Canada compared adults living in the most and least "walkable" metropolitan areas in southern Ontario and found a lower risk of developing diabetes overRead more

Iranian researchers from Isfahan University of Technology modified the properties of a magnetic material by using nanotechnology, which has many applications in various industries. Barium ferrite is a magnetic material that is used in the production of permanent magnets, magnetic sorption environment and microwave adsorbents. Size, structure, and magnetic properties of the material highly depend on the production conditions andRead more

Health-related buzzwords, such as "antioxidant," "gluten-free" and "whole grain," lull consumers into thinking packaged food products labeled with those words are healthier than they actually are, according to a new research study conducted by scholars at the University of Houston (UH). That "false sense of health," as well as a failure to understand the information presented in nutrition facts panelsRead more

The vicious fight for survival and power among disparate kingdoms and clans may have led some ancient people to evolve facial traits more quickly than others, a study said Thursday. New research on 17 skulls from a collection of 430,000-year-old remains found at the base of an underground shaft in Spain suggests that big jaws were the first prominent featureRead more

Americans who have been out of work for a year or more are much more likely to be obese, which could lead to even longer stints of unemployment for workers applying for jobs that require hard physical labor, Gallup found in a poll released Wednesday. Long term joblessness -- unemployment lasting longer than 27 weeks -- continues to be atRead more

Iranian researchers from Materials and Energy Researcher Center tried to modify the properties of thermal insulations used in turbines and thermal engines through nanotechnology. Results of the research may help the increase in thermal efficiency and lifetime of gas turbines and diesel engines. Thermal block coating (TBC) is a thermal insulation that is used in gas turbines and engines. AmongRead more

Iranian researchers applied a protecting layer to increase the resistance of stainless steel against corrosion in corrosive environments such as human body. Results of the research have applications in medical industries, specially in material implants. Metals are the oldest materials that have been used in medical industries and surgeries. The most important problem with these materials is the negative effectsRead more
