Loneliness Is A Molecule
Changes in the immune system may explain why social factors like loneliness are linked to an increased risk of heart disease, viral infections and cancer. It's already known that a person's social environment can affect their health, with those who are socially isolated--that is, lonely suffering from higher mortality than people who are not. Now researchers have identified a distinct pattern of gene expression in immune cells from people who experience chronically high levels of loneliness. The findings suggest that feelings of social isolation are linked to alterations in the activity of genes that drive inflammation, the first response of the immune system. Positioning Pelvic Cancer Patients On Stomachs For Radiation Yields Be
Positioning pelvic cancer patients on their stomachs rather than their backs is a better method for delivering radiation therapy, according to new research. Because patients return for multiple therapies, being able to reproduce the positioning of the patient allowed more precision, which reduces toxicity. Mouse Genome Will Help Identify Causes Of Environmental Disease
Research on the DNA of 15 mouse strains commonly used in biomedical studies is expected to help scientists determine the genes related to susceptibility to environmental disease. The body of data is now publicly available in a catalog of genetic variants, which displays the data as a mouse haplotype map, a tool that separates chromosomes in to many small segments, helping researchers find genes and genetic variations in mice that may affect health and disease. Many Deaths Still Expected With Earth-penetrating Nuclear Weapons
A nuclear weapon that is exploded underground can destroy a deeply buried bunker efficiently and requires significantly less power to do so than a nuclear weapon detonated on the surface would, says a new report from the National Academies' National Research Council. Over 700,000 Children Die Needlessly Every Year In The Eastern Mediter
Over 700,000 babies and children could be saved every year in the Eastern Mediterranean region if countries adopted some simple low cost health measures, say researchers in this week's British Medical Journal. USGS Scientists Document Widespread Increases In Streamflow And Change
U.S. Geological Survey (USGS) scientists have identified nationwide trends toward increasing streamflow in many areas of the nation since 1940 based on data collected from long-term USGS streamgages. This conclusion and several more interesting trends in our nation's streamflows can be found in four new fact sheets recently issued by the agency. Progeny Of Blind Cavefish Can 'Regain'Their Sight
Hybridizing blind cave fish from different cave populations can partially restore the vision of their offspring, biologists have found. The study suggests that genetic engineering can override, at least in part, half a million years of evolutionary change in one generation. [Ironic] Professional beggars prowling about the streets of Moroccan c
The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Genes, Brain Chemistry May Dictate Nicotine Cravings
Individual brain chemistry and genes could be key to understanding why some people become addicted to nicotine and why the chemical compound's effects appear to diminish at night. Diesel Exhaust May Increase Risk In Patients With Heart Disease
Air pollution could be putting patients with heart disease at risk by affecting blood vessels and clotting, researchers warn. A recent study measured the effects of diesel exhaust on heart and blood vessel function in men who have previously experienced a heart attack. The research found that inhalation of diesel exhaust caused changes in the heart's electrical activity, suggesting that air pollution reduces the amount of oxygen available to the heart during exercise.
