Flushing nitrogen from seawater-based toilets

A novel salt-tolerant bacterium cultured from the Red Sea effectively removes nitrogen from salty wastewater, suggests research from Pascal Saikaly's team at KAUST. The bacterium could be used to treat sewage coming from ...

Utah soil's slippery grip on nutrients

Lawns in the Salt Lake Valley up to 100 years old are not yet saturated in the nutrient nitrogen, which is added by fertilizer, according to a new study from University of Utah researchers. The result is surprising, since ...

Research bolsters possibility of plate tectonics on Europa

A Brown University study provides new evidence that the icy shell of Jupiter's moon Europa may have plate tectonics similar to those on Earth. The presence of plate tectonic activity could have important implications for ...

Pluto's 'heart' sheds light on a possible buried ocean

Ever since NASA's New Horizons spacecraft flew by Pluto last year, evidence has been mounting that the dwarf planet may have a liquid ocean beneath its icy shell. Now, by modeling the impact dynamics that created a massive ...

Global warming's next surprise: Saltier beaches

Batches of sand from a beach on the Delaware Bay are yielding insights into the powerful impact of temperature rise and evaporation along the shore that are in turn challenging long-held assumptions about what causes beach ...
