A new study shows that difference in water temperature between the Pacific and the Atlantic oceans together with global warming impact the risk of drought and wildfire in southwestern North America. A new model proves capable of much longer-term forecasts of mega-drought and active wildfire seasons than those currently available to people in agriculture, water management and forestry.

The sun's core rotates nearly four times faster than the sun's surface, an international team of astronomers reports. The most likely explanation is that this core rotation is left over from the period when the sun formed, some 4.6 billion years ago.

As climate change brings new pressures on wildlife, species must 'move, adapt, acclimate, or die.' Researchers have reviewed the literature on acclimation through behavioral flexibility, identifying patterns among invertebrates, amphibians, reptiles, birds, mammals, and fishes with focus on the American pika.

Chemical contamination from pesticides is a serious problem. Detection methods can be complicated, difficult to implement, and expensive. However, researchers have discovered a method to reduce the cost and simplify the process for detecting a neurotoxin found in several pesticides called Nereistoxin. It is hoped that the method will bring about improved detection techniques.
