The ability to keep CO2 out of the atmosphere to help prevent climate change is a global issue. The challenge is to use materials that can capture the CO2 and easily release it for permanent storage. Researchers at the University of Calgary and University of Ottawa have provided deeper insights to CO2 capture by "seeing" the exact sites where CO2 is held in a capture material. Their discovery, published in prestigious journal Science, will allow scientists to design better materials to capture more CO2. The findings can be likened to learning about a better fit between ...

Extra-virgin olive oil can protect the liver from oxidative stress. Researchers writing in BioMed Central's open access journal Nutrition and Metabolism exposed rats to a moderately toxic herbicide known to deplete antioxidants and cause oxidative stress, finding that those rats fed on a diet containing the olive oil were partially protected from the resulting liver damage. Mohamed Hammami from the University of Monastir, Tunisia and King Saud University, Riyadh, Saudi Arabia, worked with a team of researchers to carry out the experiments in a group of 80 rats. He said, ...

Mayer Hillman, Senior Fellow Emeritus at the Policy Studies Institute, argues that the effect of doing so would be to increase the number of 'accessible' daylight hours and thus encourage more outdoor activity throughout the year. A major public health problem contributing to the incidence of chronic illnesses in the UK is caused by lack of exercise, writes Hillman. Adults are recommended to engage in at least 30 minutes of moderate or vigorous activity daily and children at least one hour. However, surveys have revealed a trend towards declining fitness and it has been ...

DETROIT – Developing a molecular fingerprint for head and neck cancer tumors could help improve diagnosis and treatment for this deadly and often-times disfiguring form of cancer, according to researchers at Henry Ford Hospital in Detroit. Their new study has taken the first step toward doing that by identifying five risk factors for late-stage head and neck cancer – two genes, tumor grade, and vascular invasion and location of the tumor. Race, however, was not an independent predictor for late-stage disease, contrary to other research findings. In fact, 88 percent ...

Expert typists are able to zoom across the keyboard without ever thinking about which fingers are pressing the keys. New research from Vanderbilt University reveals that this skill is managed by an autopilot, one that is able to catch errors that can fool our conscious brain. The research was published in the Oct. 29 issue of Science. "We all know we do some things on autopilot, from walking to doing familiar tasks like making coffee and, in this study, typing. What we don't know as scientists is how people are able to control their autopilots," Gordon Logan, Centennial ...

GRAND RAPIDS, MICH., October 28, 2010 –The majority of Americans report getting a cold or flu in the past year, and more than a third say they'll make lifestyle changes to prevent getting sick again this year. However, 40 percent of Americans don't plan to take what is arguably the easiest and tastiest step to help potentially prevent illness this cold and flu season – eat more fruits and vegetables daily. (1) According to a newly released report, America's Phytonutrient Report: Immune Health by Color, American adults who fall short in meeting their recommended daily ...

Pittsburgh, PA— During the winter months the days grow colder and the nights longer causing households to use more electricity, often resulting in higher bills. Most households have no way of monitoring how much electricity is being consumed; however, researchers in Pittsburgh believe a new monitoring system may soon be available for residential use. The research is published in a special issue of Yale's Journal of Industrial Ecology on environmental applications of information and communication technology sponsored by CSC's Leading Edge Forum. "There are many opportunities ...

Two people can learn to cooperate with each other intuitively – without communication or any conscious intention to cooperate. But this process breaks down in groups of three or more. A study by members of the University of Leicester's School of Psychology and Department of Economics set out to explain how two people learn to cooperate without even knowing that they are interacting with each other. In larger groups, explicit communication is needed to coordinate actions. Professor Andrew Colman, Dr Briony Pulford, Dr David Omtzigt, and Dr Ali al-Nowaihi carried out ...

Is there a relation between the structure of specific regions of the brain and nicotine dependence? This is the question researchers of the Charité – Universitätsmedizin Berlin and of the Physikalisch-Technische Bundesanstalt (PTB) Berlin have been investigating lately. The results of these investigations extend and specify those of preceding studies: A specific region of the cerebral cortex of smokers is thinner than that of people who have never smoked in their lives. This region is decisive for reward, impulse control, and the making of decisions. The questions of whether ...

A new Danish study from LIFE - Faculty of Life Sciences at the University of Copenhagen shows that the parasitic disease, commonly known as snail fever, or schistosomiasis, almost eats its way into women's reproductive organs. Today researchers from all over the world are gathering in Copenhagen to find out what can be done to halt the disease which is affecting millions of women in Africa. Six hundred million people in, for example, Africa live with the daily risk of being infected with the parasitic disease schistosomiasis, otherwise known as snail fever. It happens ...

A pilot system has been launched in Tampere enabling the police to test the equipment. The aim is to develop the test equipment to match police requirements as closely as possible. The database is ...

A new study from the University of Washington reported obese children are at increased mortality risk in later years following primary liver transplantation (LT). Pediatric patients who are thin or severely thin, experience an early mortality risk—within the first year post-LT. Details of the ten-year survival analysis are published in the November issue of Liver Transplantation, a peer-reviewed journal of the American Association for the Study of Liver Diseases (AASLD). Childhood obesity is a serious public health concern worldwide. According to the World Health Organization ...

The researchers, in partnership with the Cancer Council, Australia, studied 12,618 food advertisements from 11 countries and found that 67 per cent endorsed unhealthy food. The research builds on a previous study at Liverpool which revealed that children would consume twice as many calories from snacks after watching food adverts compared to after viewing advertising for toys and games. The research reveals that Germany, Spain and Greece have the highest frequency of adverts promoting unhealthy foods during children's peak viewing time, compared to other European countries ...

Researchers from North Carolina State University have found a way to optimize the development of DNA self-assembling materials, which hold promise for technologies ranging from drug delivery to molecular sensors. The key to the advance is the discovery of the "Goldilocks" length for DNA strands used in self-assembly – not too long, not too short, but just right. DNA strands contain genetic coding that will form bonds with another strand that contains a unique sequence of complementary genes. By coating a material with a specific DNA layer, that material will then seek ...

(Boston) A team of researchers from Boston University's Center for Regenerative Medicine and the Pulmonary Center have generated 100 new lines of human induced pluripotent stem cells (iPSC) from individuals with lung diseases, including cystic fibrosis and emphysema. The new stem cell lines could possibly lead to new treatments for these debilitating diseases. The findings, which appear in the current issue of Stem Cells, demonstrate the first time lung disease-specific iPSC have been created in a lab. iPSCs are derived by reprogramming adult cells into a primitive stem ...

More than 251 million years ago, at the end of the Permian period, Earth almost became a lifeless planet. Around 90 percent of all living species disappeared then, in what scientists have called "The Great Dying." Thomas J. Algeo, has spent much of the past decade investigating the chemical evidence buried in rocks formed during this major extinction. The University of Cincinnati professor of geology has worked with a team of scientific colleagues to understand the ancient catastrophe. Algeo will present his latest findings at the annual meeting of the Geological Society ...

PHILADELPHIA - A recently identified immune cell that directs other cells to fight infection plays a critical role in regulating the immune system in both health and disease. Researchers from the University of Pennsylvania School of Medicine have discovered how a stimulatory molecule and a protein found on the membrane of another immune cell make T helper 17 cells multi-taskers of sorts. Th17 cells protect the body against infection and cancer, but are also culprits in some autoimmune diseases and out-of-control, cancerous cell growth. This new understanding that Th17 ...

With Election Day right around the corner, political egos are on full display. One might even think that possessing a "big ego" is a prerequisite for success in politics, or in any position of leadership. High achievers–CEO's, top athletes, rock stars, prominent surgeons, or scientists–often seem to be well endowed in ego. But when does a "healthy ego" cross the line into unhealthy territory? Where is the line between confident, positive self-image and grandiose self-importance, which might signal a personality disorder or other psychiatric illness? More fundamentally, ...

The virus, called enterovirus 71, is closely related to poliovirus, and was first detected in California in the 1960s. Since then the virus has spread across Asia, affecting mostly children and some adults. Serious cases of the disease can include neurological disorders such as meningitis, paralysis and encephalitis. As a result of a global health campaign, polioviruses have almost been eradicated in many areas of the world. Enterovirus 71, however, has caused major outbreaks of hand, foot, and mouth disease and it is still unclear why such a high number of cases occur ...

Ancient gardens are the stuff of legend, from the Garden of Eden to the Hanging Gardens of Babylon. Now researchers at Tel Aviv University, in collaboration with Heidelberg University in Germany, have uncovered an ancient royal garden at the site of Ramat Rachel near Jerusalem, and are leading the first full-scale excavation of this type of archaeological site anywhere in the pre-Hellenistic Levant. According to Prof. Oded Lipschits and graduate student Boaz Gross of Tel Aviv University's Department of Archaeology, this dig is an unparalleled look into the structure ...

Millions of Medicare recipients have been forcibly reassigned to different prescription drug plans because Part D reimbursements to insurance companies covering low-income patients are lower than the actual costs incurred, according to a study released online today by Health Affairs. The report describes how a system designed to encourage competition and to subsidize care for low-income Medicare patients instead has led companies to raise their premiums in an effort to price themselves out of the low-income segment of the Part D market. "These insufficient payments create ...

MINNEAPOLIS / ST. PAUL Minn. (October 28, 2010) – University of Minnesota Medical School and Minneapolis Veterans Affair Medical Center researchers have discovered a correlation between increased circuit activity in the right side of the brain and the debilitating, involuntary flashbacks triggered by post traumatic stress disorder (PTSD). The ability to objectively diagnose PTSD through concrete evidence of neural activity, its impact and its manifestation is the first step towards effectively helping those afflicted with this severe anxiety disorder. PTSD often stems ...
