Record low ice concentrations found in the Arctic’s “Last Ice Area”

The Arctic's "Last Ice Area," a region where summer sea ice is expected to survive the longest and therefore act as a refuge for the wildlife that depends on it, is already feeling the effects of climate change, new research shows.

Willow trees used to produce helpful substances while treating sewage

Even with today's various sewage-treatment technologies, a great deal of municipal wastewater is still released back into waterways either partially or completely untreated. According to a new study, however, plots of willow trees could be used to clean it up – while also producing useful materials.
