Philadelphia, PA, July 7, 2014 – Sedentary lifestyle and not caloric intake may be to blame for increased obesity in the US, according to a new analysis of data from the National Health and Nutrition Examination Survey (NHANES). A study published in the American Journal of Medicine reveals that in the past 20 years there has been a sharp decrease in physical exercise and an increase in average body mass index (BMI), while caloric intake has remained steady.

MADISON — When it comes to science, socioeconomic status may widen confidence gaps among the least and most educated groups in society, according to a new study by researchers at the University of Wisconsin-Madison's Science, Media and the Public research group.
The findings, published in June in the journal Science Communication, show that similar levels of attention to science in newspapers and on blogs can lead to vastly different levels of factual and perceived knowledge between the two groups.
An important development in understanding how the bacterium that causes pneumonia, meningitis and septicaemia remains harmlessly in the nose and throat has been discovered at the University of Liverpool's Institute of Infection and Global Health.
Streptococcus pneumoniae is a 'commensal', which can live harmlessly in the nasopharynx as part of the body's natural bacterial flora. However, in the very young and old it can invade the rest of the body, leading to serious diseases such as pneumonia, sepsis and meningitis, which claim up to a million lives every year worldwide.
COLUMBIA, Mo. – Problematic eating behaviors and dissatisfaction with one's body are familiar struggles among women. To combat those behaviors, which have led to higher healthcare premiums and medical trends, employers have offered worksite wellness programs to employees and their families. However, the vast majority of wellness programs limit their approach to promoting diets, which may result in participants regaining the majority of their weight once the programs end.
In addition to providing regular assessments of scientific literature, the Intergovernmental Panel on Climate Change Process (IPCC) also produces a "Summary for Policymakers" intended to highlight relevant policy issues through data.
PROVIDENCE, R.I. [Brown University] — When landlords have followed Rhode Island's law requiring them to protect tenants from exposure to lead, their compliance has significantly reduced blood levels of the toxic metal in children. But in four of the state's major cities, only 20 percent of properties that are covered by the law were in compliance with the law even more than four years after it took effect, according to a study by researchers at Brown University, The Providence Plan, HousingWorks RI, and the Rhode Island Department of Health.
Scientists from North Carolina State University and the University of Florida have combined cookies, citizen science and robust research methods to track the diversity of ant species across the United States, and are now collaborating with international partners to get a global perspective on how ants are moving and surviving in the modern world.
Age limits on clinical trials need to be more flexible to allow more teenage cancer patients the chance to access new treatments, according to a report from the National Cancer Research Institute (NCRI), published in the Lancet Oncology.
The study, funded by the National Institute for Health Research and Teenage Cancer Trust, found that trials designed with broader age limits resulted in more teenagers and young adults going on clinical trials.
(PHILADELPHIA) -- In the largest study to date comparing sutures (stitches) versus surgical staples for closing a C-section, researchers found a 57 percent decrease in wound complications in women who were sutured versus those who received staples. By carefully addressing the concerns that previous studies had raised, the research shows a clear benefit of suture for women.
July 7, 2014, Shenzhen, China— Researchers from BGI, working within the Metagenomics of the Human Intestinal Tract (MetaHIT) project, and in collaboration with other institutions around the world , have established the highest quality integrated gene set for the human gut microbiome to date- a close-to-complete catalogue of the microbes that reside inside us and massively outnumber our own cells.
China's richest provinces have an outsized environmental impact on the country's water-scarce regions, according to new research from the International Institute for Applied Systems Analysis (IIASA) and the University of Maryland.
Researchers at Karolinska Institutet in Sweden have headed a study that provides new knowledge about the EphA2 receptor, which is significant in several forms of cancer. This is important knowledge in itself – but just as important is how this study, which is published in the highly respected journal Nature Methods, was conducted. The researchers used the method of DNA origami, in which a DNA molecule is shaped into a nanostructure, and used these structures to test theories about cell signalling.
Alicia Boole Stott, the third daughter of mathematician George Boole, is probably best known for establishing the term "polytope" for a convex solid in four dimensions. Alicia was also a long time collaborator of HSM Coxeter, one of the greatest geometers of the 20th Century.
The 64th Lindau Nobel Laureate Meeting ended with a panel discussion entitled "Science for the benefit of mankind" on Mainau Island, Lake Constance, Germany, today." 37 Nobel laureates and more than 600 selected young scientists from 80 countries had participated in the week-long meeting in the Bavarian city of Lindau since last Sunday. A boat trip to Mainau at the invitation of the State of Baden-Württemberg marked the finish of the programme which was devoted to medicine and physiology.
Institute for Basic Science (IBS), the main organization of the International Science and Business Belt project in South Korea, has announced that a group of researchers, led by professor Won Do Heo, have developed a new technology in the field of optogenetics that can remotely control specific receptors by light. They have named this new technology "OptoTrk" and it has succeeded with neuronal differentiation inducement.
