Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports. Molecular chlorine, from sea salt released by melting sea ice, reacts with sunlight to ...
A team of researchers with North-West University in Potchefstroom, South Africa has for the first time captured on video, a freshwater fish leaping out of the water and into the air to grab a flying bird. The video was part of research the ...
