New evidence gathered in a study funded by the National Institute of Environmental Health Sciences suggests that asthmatic children who use maintenance medication are particularly vulnerable to the effects of ground-level ozone, even at levels well below the federal standard set by the Environmental Protection Agency.
Their research results were published Oct. 8 in the Journal of the American Medical Association. The study was conducted at the Yale University School of Medicine. NIEHS is one of the federal National Institute of Health.
"Although the 1-hour average ozone levels in our study were well below the federal standard, statistical analysis revealed that for every 50 parts per billion increase in ozone, the likelihood of asthma symptoms the following day increased by more than 35 percent among asthmatic children on maintenance medication," said Brian Leaderer, Ph.D., the Susan Dwight Bliss Professor of Epidemiology at Yale University and principal investigator for the study.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
