Fossil-Fuel Plastics May Fuel Toxic Algae Blooms, UCSD Study Finds

A new UC San Diego study finds that petroleum-based microplastics can help drive harmful algae blooms by wiping out tiny animals that normally keep algae in check. Biodegradable plastics tested in the same experiment had a much smaller impact.

Shrubs Turn China’s Largest Desert Rim Into a Carbon Sink

Along the rim of China’s Taklamakan Desert, a 40-year experiment in planting hardy shrubs is slowing desert expansion and quietly soaking up carbon dioxide. New satellite-based research shows even one of the world’s driest places can become a measurable carbon sink.

How Office Movement Is Helping Scientists Map Indoor Air Pollution

A Birmingham-led team has shown how everyday movement in offices can stir up indoor air pollution — and how radar and low-cost sensors could help engineers design healthier buildings.
