NASA Scientists identify Molecule in Titan’s Atmosphere that’s never been seen before

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA scientists identified a molecule in Titan’s atmosphere that has never been detected in any other atmosphere. In fact, many chemists have probably barely heard of it or know how to pronounce it: cyclopropenylidene, or C3H2. Scientists say that this simple carbon-based molecule may be a precursor to more complex compounds that could form or feed possible life on Titan.

Researchers found C3H2 by using a radio telescope observatory in northern Chile known as the Atacama Large Millimeter/submillimeter Array (ALMA).

These infrared images of Saturn's moon Titan represent some of the clearest global views of the icy moon's surface. The views were created using 13 years of data acquired by the Visual and Infrared Mapping Spectrometer instrument onboard NASA's Cassini spacecraft.

American Heart Association: Environmental toxins linked to heart defects

 

American Heart AssociationDallas, TX – Children’s congenital heart defects may be associated with their mothers’ exposure to specific mixtures of environmental toxins during pregnancy, according to research presented at the American Heart Association’s Scientific Sessions 2013.

Congenital heart defects occur when the heart or blood vessels near the heart don’t develop normally before birth. Defects may be caused by chromosomal abnormalities, but the cause is unknown in most cases. «Read the rest of this article»
