Unregulated trash burning around the globe is pumping far more pollution into the atmosphere than shown by official records. A new study led by the National Center for Atmospheric Research estimates that more than 40 percent of the world's garbage is burned in such fires, emitting gases and particles that can substantially affect human health and climate change.

Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions?

Verizon announced today that it will invest nearly $40 million to expand the on-site green energy program that it launched in 2013. This year, Verizon will install 10.2 megawatts of new solar power systems at eight Verizon network facilities in five states – California, Maryland, Massachusetts, New Jersey and New York. This investment nearly doubles the amount of renewable power generated by solar energy systems installed at six Verizon facilities last year.

Ever wonder how lizards like Geckos can walk up walls and even across the ceiling? Is it sticky feet, anti-gravity, or what?
Researchers at Oregon State University have developed a model that explains how geckos, as well as spiders and some insects, can run up and down walls, cling to ceilings, and seemingly defy gravity with such effortless grace.
This ability, outlined today in the Journal of Applied Physics, is a remarkable mechanism in the toes of geckos that uses tiny, branched hairs called "seta" that can instantly turn their stickiness on and off, and even "unstick" their feet without using any energy.

A strong earthquake hit the Napa valley yesterday.
The US Geological Survey has provided a detailed summary of the quake and the possibilities of both strong aftershocks and the remote potential of an aftershock stronger than the quake (Magnitiude 6.0)
The earthquake occurred within a 70-km-wide (44 miles) set of major faults of the San Andreas Fault system that forms the boundary between the Pacific and North American tectonic plates. The persistent northwestward movement of the Pacific plate relative to North America primarily causes right-lateral slip across the major faults, but also causes deformation between the major faults. The ongoing complex deformation field is revealed by modern geodetic surveys and earthquake patterns as well as the regional geologic structure.
