For almost two years, the honeybees that support almost all human agriculture have fought a plague right out of a sci-fi movie. Varroa mites, a deadly parasite, have hid in the labyrinthine combs of beehives, feeding off the juices of still-living insects, and causing the the problem we know as Colony Collapse Disorder.
To help our bee allies fend off the alien invaders, the Agriculture Research Service division of the Department of Agriculture has created a new breed of super-vigilant bees that will take the fight to the mites.
In an attempt to both strengthen the US's negotiating hand in the upcoming Copenhagen climate talks, and to prod domestic lawmakers into swifter action on lasting legislation, the White House has told the Environmental Protection Agency to move forward with new rules regulating greenhouse gas emissions.
America’s first National Park, Yellowstone, is home to some of the richest wildlife on Earth beyond the plains of Africa.

We here at PopSci enjoy our green dreams for future buildings as much as any other geek. So imagine the excitement when Beijing-based MAD Ltd. unveiled its solar eco-skin design for the Taichung Convention Center in Taiwan.
The landmark building design aims to meld future tech with natural shapes that evoke mountains dotted with crater-like openings. We can only hope that a recovering post-apocalyptic landscape would look so pleasing.
Publishing in the journal Nature, a group of 29 scientists have established a comparative scale for rating the immediate threat posed by nine environmental hazards--everything from climate change to ocean acidification. And while our warming climate gets most of the attention, more immediate problems may be brewing in our intensifying lack of biodiversity and out-of-whack nitrogen cycle.
Today, heads of state from around the globe met at the United Nations to face a problem that affects all of their constituencies: climate change. In a day-long conference on global warming, President Obama lamented that the United States was slow to recognize and respond to the problem of global warming, and vowed to move swiftly to counter it. President Hu Jintao of China echoed those statements, listing a four-point plan to combat carbon emissions.
In the hope of combating anorexia, 50 members of the French Assembly have proposed a bill that would require magazines to label any portraits that have been digitally altered. They claim that slimmed-down pics of celebs lead to anorexia in young women looking to attain unrealistic body sizes.
A decade ago, the bells of doom started to sound for carefree, swinging koalas. A new, HIV-like retrovirus had begun to attack the koala population, decimating its ranks and threatening extinction.
Now, the Australian researchers have launched an effort to stop the spread of the virus before it's too late.
A new kind of energy-efficient light bulb may provide an alternative to existing compact fluorescent (CFL) and Light Emitting Diode (LED) bulbs. The new bulbs, made by Seattle-based Vu1, use a technology called electron stimulated luminescence (ESL) to produce incandescent-quality light.
The ESL bulbs generate light by firing electrons to stimulate phosphor, and the whole setup is encased in normal light-bulb glass. The bulbs are estimated to last up to 6,000 hours, which is comparable to CFLs, and three to four times as long as incandescent bulbs.
