Offsetting global warming: Targeting solar geoengineering to minimize risk and inequality

Posted: 21 Oct 2012 10:39 AM PDT

By tailoring geoengineering efforts by region and by need, a new model promises to maximize the effectiveness of solar radiation management while mitigating its potential side effects and risks.

Fishy physics: Adaptation lets silvery fish reflect light without polarization, may help them evade predators

Posted: 21 Oct 2012 10:39 AM PDT

Silvery fish such as herring, sardine and sprat have evolved special skin that gets around a basic law of physics, according to new research. Reflective surfaces polarize light, a phenomenon that fishermen or photographers overcome by using polarizing sunglasses or polarizing filters to cut our reflective glare. However, researchers found that these silvery fish have overcome this basic law of reflection -- an adaptation that may help them evade predators.
