The ozone hole that forms over the Antarctic each September is primarily driven by two factors: the amount of ozone-destroying chlorine in the polar stratosphere and the availability of ice crystals in stratospheric clouds for the chlorine to bind to. This year, the super-cold stratospheric temperatures measured by NOAA and NASA meant conditions were ripe for the development of ice clouds - and a big ozone hole.

Researchers at the University of Waterloo have developed a new system that could significantly speed up the discovery of new drugs and reduce the need for costly and time-consuming laboratory tests.
Autonomous Vehicles Could Shape the Future of Urban Tourism
In the first study of its kind, published in the Annals of Tourism Research, academics from the University of Surrey and the University of Oxford have examined how Autonomous Vehicles (AVs) may have a substantial impact on the future of urban tourism.
NASA Sees Tropical Cyclone Alcide Reach Hurricane Strength
NASA’s Terra satellite provided a visible image of a more organized Tropical Cyclone Alcide in the Southern Indian Ocean after it reached hurricane-force.
ASU Geoscientists Discover an Overlooked Source for Earth's Water
Where did Earth's global ocean come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents' Professor in ASU’s School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has found an answer in a previously neglected source. The team has also discovered that our planet contains considerably more hydrogen, a proxy for water, than scientists previously thought.
New Hope for World’s Most Endangered Mammal
New genetic analysis of white rhino populations suggests it could be possible to rescue the critically endangered northern white rhinoceros from extinction, using the genes of its less threatened southern cousin.
