Laughing Gas May Have Helped Warm Early Earth and Given Breath to Life

Georgia Institute of Technology

Laughing gas and the mystery of Carl Sagan's Faint Young Sun Paradox: When the sun shone dimmer an eon ago, Earth remained warm in spite of it likely thanks to a mix of greenhouse gases. Biogeochemists have now shown how N20, known today for its use as a dental anesthetic, may have made it into the mix.

Demonstrated Natural Refrigerant Replacements Could Reduce Energy Costs and Conserve the Environment

American Institute of Physics (AIP)

The 1987 Montreal Protocol and the 1997 Kyoto Protocol called for countries around the world to phase out substances that deplete the ozone layer and cause global warming, but many HVAC systems still use synthetic refrigerants that violate those international agreements and inflict environmental damage. Recently, Iranian researchers investigated how natural refrigerants could be used in geothermal heat pumps to reduce energy consumption and operating costs. They report their findings in the Journal of Renewable and Sustainable Energy.

Sight Unseen: Novel Method Detects Evidence of Unmarked Human Graves

Oak Ridge National Laboratory

A new approach to find unmarked gravesites could help narrow the scope and potentially speed up the search for clues during crime scene investigations. Geospatial researchers with the Department of Energy’s Oak Ridge National Laboratory and forensic scientists at University of Tennessee used LIDAR to detect telltale signs of recently buried human remains.

Chemistry Research ‘Rocks’ New Data about Ancient Life

University of California San Diego

Sulfur isotopes can serve as tracers of atmospheric oxygen, and new data collected from the present-day atmosphere in China by an international team of researchers, led by the University of California San Diego, indicate remarkable similarity to the isotopic footprint found in ancient rocks. This opens up new interpretations of the Archean Period’s sulfur isotope sedimentary signature—a proxy for the origins and evolution of atmospheric oxygen and early life on Earth.
