Emissions and asthma | Autoimmunity | Dopamine in addiction

April 21, 2020 Edition COVID-19 is an emerging, rapidly evolving situation, and we at NIH are doing everything we can toward the development of diagnostics, therapeutics, and vaccines. You can find the latest public health information from CDC at www.coronavirus.gov and the latest research information from NIH at www.nih.gov/coronavirus. Meanwhile, science continues to progress on many other fronts, and we will continue to try to bring you stories across a wide range of topics. Drop in coal power plant emissions associated with asthma improvements Reductions in sulfur dioxide emissions from coal-fired power plants were associated with fewer local hospitalizations and emergency department visits due to asthma. Marker of autoimmunity increases in U.S. Autoimmunity may be on the rise, based on a study of antinuclear antibodies in blood samples collected nationwide from 1988-2012. Dopamine modification on chromatin linked to addiction Researchers found that dopamine can modify the structure that DNA is packed into and alter gene expression following cocaine exposure.
