New Insight Into Climate Impacts of Deforestation
Deforestation is likely to warm the climate even more than originally thought, scientists warn.
Marijuana Farms Expose Spotted Owls to Rat Poison in Northwest California
Wildlife species are being exposed to high levels of rat poison in northwest California, with illegal marijuana farms the most likely source point, according to a study led by the University of California, Davis, with the California Academy of Sciences.
NASA's Great Observatories Team Up to Find Magnified and Stretched Image of Distant Galaxy
An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing.
