According to a new survey of America's beekeepers, almost a third of the country's honeybee colonies did not make it through the winter.
That's been the case, in fact, almost every year since the U.S. Department of Agriculture began this annual survey, six years ago.
Over the past six years, on average, 30 percent of all the honeybee colonies in the U.S. died off over the winter. The worst year was five years ago. Last year was the best: Just 22 percent of the colonies died.
Some things you just count on. Like if we ever meet a space alien, it should have eyes (and maybe a head). Like somewhere out there, there are planets like ours. Like we have an ordinary solar system — "ordinary" because you know what it looks like ...
It's got a sun in the middle, little planets on the inside, bigger ones farther out. That's what most of them should look like, no?
American companies that do business with China make good money. They also lose a lot of money there to cyberthieves, who routinely hack into the computers of the U.S. firms and steal their trade and technology secrets.
The economy may be on the rebound, but many cultural institutions are still struggling to regain their financial footing. That's especially true for one of the country's most recognized museums — the Field Museum of Natural History in Chicago. Known internationally for its research as well as its exhibits, the Field Museum must pay off millions in bond debt — and toe an ethical line as it does.
The Earth's wettest regions are likely to get wetter while the most arid will get drier due to warming of the atmosphere caused by increased levels of carbon dioxide, according to a new NASA analysis of more than a dozen climate models.

A smartphone can tell you where to get a cup of coffee, but it can't go get the coffee for you. Engineers would like to build little machines that can do stuff. They would be useful for a lot more than coffee, if we could figure out how to make them work.
But the rules of mechanics change at small scales. Friction becomes dominant; turbulence can upend a small airplane.
NASA is raising awareness for its upcoming launch of the Mars Atmosphere and Volatile Evolution spacecraft with its Going to Mars project. The MAVEN spacecraft is scheduled for launch this November, to study the Red Planet's upper atmosphere; the craft will examine why Mars lost its atmosphere, and how that catastrophe affected the history of water there.
NASA is calling it "The Rose." By any other name, it's a mammoth storm on Saturn's north pole. Its eye spans an estimated 1,250 miles — 20 times the size of an average hurricane's eye on Earth. Winds in the Saturn storm's eye wall are believed to be four times as fast.
The stunning image of the spinning vortex was given "false colors" to emphasize low clouds (in red) versus high clouds (in green). NASA estimates that the clouds at the outer edge are moving at up to 330 miles per hour.
