Fitness Reduces Inflammation, Study Suggests
A number of studies have suggested that regular exercise reduces inflammation -- a condition that is predictive of cardiovascular and other diseases, such as diabetes. If such a link exists, the nature of the relationship is by no means fully understood. A recent study provides new evidence that may help explain some of the underlying biological mechanisms that take place as the result of regular exercise. Eclipses yield first images of elusive iron line in the solar corona
Solar physicists attempting to unlock the mysteries of the solar corona have found another piece of the puzzle by observing the sun's outer atmosphere during eclipses. Non-maternal Care Linked To Reduced Physical Aggression In Children Of
Among children of mothers with low education levels, those who receive regular care from other adults during preschool years may be less likely to have problems with physical aggression, according to a new article. Alzheimer's detection: What's his name again? How celebrity monikers c
Famous mugs do more than prompt us into buying magazines, according to new research. Scientists explain how the ability to name famous faces or access biographical knowledge about celebrities holds clues that could help in early Alzheimer's detection. Martin Luther King, Jr. Day of Service
"The King Day of Service is a way to transform Dr. Martin Luther King, Jr.'s life and teachings into community service that helps solve social problems."Includes a tool for finding an MLK Day service project in your area, plus project tips, PR resources, logos, reading lists, and more. From the Corporation for National &Community Service, "a federal agency that gives more than a million Americans opportunities to improve communities through service." The A to Z Guide to Political Interference in Science
Descriptions of several situations in which "scientists who work for and advise the federal government [in the 21st century] have seen their work manipulated, suppressed, [and] distorted."Also includes a link to a list from December 2006 of "names of more than 10,000 scientists of all backgrounds from all 50 states -- including 52 Nobel Laureates"who "signed a scientist statement on scientific integrity, denouncing political interference in science."From the Union of Concerned Scientists. Women Still Face Cancer Risk 25 Years After Treatment
Women are still at risk of developing invasive cancer of the cervix or vagina 25 years after being treated for precancerous lesions, according to a new study. Women who have had severe cell changes in the cervix and who have been operated on for them run twice the risk of developing cancer later in life, compared with other women. Cancer experts are now calling for cytological smears to be offered at regular intervals for at least 25 years after a woman has had severe dysplasia/CIS (carcinoma in situ). Micro RNAs And Musculature
In an effort to understand the biological function of the microRNA mir1, Drs. Nicholas Sokol and Victor Ambros (Darmouth Medical School) have studied the expression profile, transcriptional regulation and loss-of-function phenotype of Drosophila mir-1 (Dmir-1). Strikingly, their study shows that, in Drosophila embryos, mir-1 expression is not required for mesodermal cell fate decisions or cell proliferation during embryogenesis, but rather, that it appears to act to reinforce and maintain cell identity during times of rapid growth. UN Issues Analysis Of Global Investors'Sustainable Energy 'Gold Rush'
Climate change worries coupled with high oil prices and increasing government support top a set of drivers fueling soaring rates of investment in the renewable energy and energy efficiency industries, according to a trend analysis from the UN Environment Programme. Light That Travels ... Faster Than Light!
A team of researchers from the Ecole Polytechnique Fédérale de Lausanne (EPFL) has successfully demonstrated, for the first time, that it is possible to control the speed of light -- both slowing it down and speeding it up -- in an optical fiber, using off-the-shelf instrumentation in normal environmental conditions. Their results, to be published in the August 22 issue of Applied Physics Letters, could have implications that range from optical computing to the fiber-optic telecommunications industry.
