Human-caused climate change, ocean acidification and species extinctions may eventually threaten the collapse of civilization, according to some scientists, while other people argue that for political or economic reasons we should allow industrial development to continue without restrictions.

As the Appalachian Region feels the impact of the burgeoning shale-energy industry, a consortium of researchers and industrial partners led by West Virginia University, with the assistance of The Ohio State University, will conduct the first-ever long-term, comprehensive field study of a natural resource that has changed the country’s – and the world’s – energy supply.

With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents, should the need arise. In the American Chemical Society journal ACS Nano, they describe new spherical micromotors that rapidly neutralize chemical and biological agents and use water as fuel.

These two infrared images of C/2013 (Comet Siding Spring) were taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard NASA’s Mars Reconnaissance Orbiter (MRO) on Oct. 19, 2014. Comet Siding Spring — an Oort Cloud comet that may contain material from the formation of the solar system some 4.6 billion years ago — was making its first voyage through the inner solar system. CRISM and many other instruments and spacecraft combined to provide an unprecedented data set for an Oort Cloud comet.
