We've all heard people say 'I won't kiss you, I've got a cold'. But a report just published warns that we may be far more at risk of passing on an infection by shaking someone's hand than in sharing a kiss.
Anyone heading out to the local skatepark with dreams of becoming the next Tony Hawk may want to take some precautions.
A research team led by Dr. Pierre Moffatt of the Shriners Hospital for Children in Montreal and McGill University’s Department of Human Genetics has uncovered the molecular mechanism by which the protein osteocrin controls bone growth – a discovery that may have important implications for people suffering from bone diseases affecting skeletal growth. The team’s findings appear in the December 14 edition of the Journal of Biological Chemistry.
‘Science’ has published the results of this research. The so-called Pierre Auger Collaboration, with headquarters in Argentina and participation from the UGR, has proved that there is an anisotropy in the arrival directions of the most energetic particles ever detected, correlated with areas in which there are galaxies with active nuclei in the centre. These conclusions have been obtained from the first data provided by the Pierre Auger Observatory of the Southern Hemisphere in Argentina.
A detailed analysis of soil samples taken from a forest ecosystem with artificially elevated levels of atmospheric carbon dioxide reveals distinct changes in the mix of microorganisms living in the soil below trembling aspen. These changes could increase the availability of essential soil nutrients, thereby supporting increased plant growth and the plants' ability to "lock up," or sequester, excess carbon from the atmosphere.
Using a large population survey in India, a new study from Harvard School of Public Health researchers has found an association between domestic violence and adult smoking.
A new report issued today by the Access Project and Brandeis University found that farm and ranch operators, like many Americans, are seriously challenged by the cost of health care. One in four said that health care costs contributed to financial problems for their families.
Using observations from ESO’s VLT, astronomers were able for the first time to reconstruct the site of a flare on a solar-like star located 150 light years away. The study of this young star, nicknamed ‘Speedy Mic’ because of its fast rotation, will help scientists better understand the youth of our Sun.
The astronomers [1] observed the star BO Microscopii [2] during two consecutive nights in October 2006, simultaneously with the UVES spectrograph on ESO’s Very Large Telescope and ESA’s XMM-Newton X-ray satellite.
Most parents would hotly deny favoring one child over another but new research suggests they may have little choice in the matter.
A study by Dr. Kitasato and colleagues demonstrated that cytokine stimulation induced iNOS expression and NO generation, which was sufficient to cause DNA damage in normal hamster gallbladder epithelial cells. These findings suggest that NO-mediated oxidative DNA damage produced by inflammatory cytokines through iNOS expression is involved in an initiation process that links chronic biliary inflammation to malignant transformation.
