At a Smaller Dose, Solar Geoengineering Could be Safe

At a Smaller Dose, Solar Geoengineering Could be Safe

Sometimes half a dose of medicine is enough. A new study published in Nature Climate Change says that might also be true with solar geoengineering if we want to avoid its potential side effects. Solar geoengineering involves spraying the atmosphere with tiny particles...
Firefly-inspired LEDs Shine Bright On Less Energy

Firefly-inspired LEDs Shine Bright On Less Energy

Symmetry isn’t always appealing. By mimicking the lopsided structures found on firefly bellies, researchers have come up with a new light-emitting diode (LED) that could use less energy than today’s LED light bulbs. The design, reported in the journal Optik, consists...
New Artificial Leaf Ready to See Light of Day

New Artificial Leaf Ready to See Light of Day

Scientists have for years tried to mimic plants’ ability to convert carbon dioxide and water into energy. But artificial leaf devices made so far have not worked quite as well in the real world as they do in the laboratory. For a practical design, researchers at the...
New Technique Converts Plastic Waste to Fuel

New Technique Converts Plastic Waste to Fuel

One strategy to fight plastic pollution is to convert oceans of plastic trash into something valuable. The latest in this approach comes from a team at Purdue University, which has devised a method to convert a commonly used plastic into oil. The process, reported...
