I'm going to tell two stories here, two very different stories. One's about bad guys hurting good guys that made me think the world is going to hell; the other is about good guys outfoxing bad guys and made me smile — made me think there's hope, always hope. I found them in different books.
Scientists are reporting an advance in the science of aging and maybe even a clue how to reverse some of aging's effects. They have evidence that lifestyle changes already known to be good for you, like healthy diet, exercise, reducing stress may prevent the chromosomes in our cells from unraveling.
NPR's Richard Knox reports that it's all about little caps on our chromosomes called telomeres.
How often do whales clean their ears? Well, never. And so, year after year, their earwax builds up, layer upon layer. According to a study published Monday, these columns of earwax contain a record of chemical pollution in the oceans.
The study used the earwax extracted from the carcass of a blue whale that washed ashore on a California beach back in 2007. Scientists at the Santa Barbara Museum of Natural History collected the wax from inside the skull of the dead whale and preserved it. The column of wax was almost a foot long.
From the standpoint of global warming, burning natural gas can be better than burning coal, a study published this week suggests.
This is a contentious issue among people who are opposed to the natural gas drilling practice known as fracking. That technique involves injecting water, sand and chemicals into wells to release far more gas than conventional drilling can. Opponents of fracking have been concerned not only about local environmental issues, but also about the potential for methane leaks to make global warming worse.
Five years ago this week, a Canadian company proposed building a pipeline to send heavy crude oil from Alberta to U.S. refineries. Although the Obama administration's answer on the Keystone XL pipeline is not expected anytime soon, politicians in Washington and Canada are ramping up the pressure for the project, while environmentalists are pushing hard against it.
Scientists watching Antarctica's Pine Island Glacier from space have noticed with some alarm that it has been surging toward the sea.
If it were to melt entirely, global sea levels would rise by several feet.
The glacier is really, really remote. It's 1,800 miles from McMurdo, the U.S. base station in Antarctica, so just getting there is a challenge. Scientists have rarely been able to get out to the glacier to make direct measurements.
Darwin the 'Ikea monkey' will no longer be hitting the superstores with a Canadian woman who calls him her son after a judge in Ontario ruled that the primate is not a pet and should remain at an animal sanctuary.
As we wrote in December, Darwin, a Japanese macaque dressed in a heavy shearling coat, attracted considerable attention when he escaped from a locked crate in owner Yasmin Nakhuda's car in Toronto. He made his way through rows of parked cars and ended up inside a nearby Ikea store before staff there cornered him and called in animal control officials.
Human DNA is the ultimate fingerprint. A single hair can contain enough information to determine someone's identity — a feature that's been invaluable for identifying the unnamed casualties of natural disasters and war. But forensic scientists who use DNA say the technology isn't always available where it's most needed, like in poor countries, or in war zones like Syria.
For several weeks now, two unmanned spy planes have been flying over the Atlantic on an unusual mission: gathering intelligence about tropical storms and hurricanes.
The two Global Hawk drones are a central part of NASA's five-year HS3 (Hurricane and Severe Storm Sentinel) Mission investigating why certain weather patterns become hurricanes, and why some hurricanes grow into monster storms.
