On June 17, NASA’s MAVEN (Mars Atmosphere and Volatile Evolution Mission) will celebrate 1,000 Earth days in orbit around the Red Planet. Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.

California’s winter rains and snow depress the Sierra Nevada and Coast Ranges, which then rebound during the summer, changing the stress on the state’s earthquake faults and causing seasonal upticks in small quakes, according to a new study by University of California, Berkeley seismologists.

The weight of winter snow and stream water pushes down the Sierra Nevada mountains by about a centimeter, or three-eighths of an inch, while ground and stream water depress the Coast Ranges by about half that. This loading and the summer rebound – the rise of the land after all the snow has melted and much of the water has flowed downhill – makes the earth’s crust flex, pushing and pulling on the state’s faults, including its largest, the San Andreas.

Reducing meat consumption and using more efficient farming methods globally are essential to stave off irreversible damage to the environmental, a new study says.

The research, from the University of Minnesota, also found that future increases in agricultural sustainability are likely to be driven by dietary shifts and increases in efficiency, rather than changes between food production systems.

Researchers examined more than 740 production systems for more than 90 different types of food, to understand the links between diets, agricultural production practices and environmental degradation. Their results are published today in the journal Environmental Research Letters.

A scientific breakthrough has taken an emerging biotechnology a step closer to being used to treat wastewater in the Developing World.

Researchers at the University of the West of England (UWE Bristol) (Ieropoulos & Greenman) have discovered that technology they have developed which has already been proven to generate electricity through the process of cleaning organic waste, such as urine, also kills bacteria harmful to humans.
