The Fierce People. That's what anthropologist Napoleon Chagnon called the indigenous Ya̧nomamö Indians of Venezuela in his 1968 book Ya̧nomamö: The Fierce People. It's one of the best-selling anthropology texts of all time and is still in wide use.

Wild Bees Are Good For Crops, But Crops Are Bad For Bees

Wild bees, such as this Andrena bee visiting highbush blueberry flowers, play a key role in boosting crop yields.

Some of the most healthful foods you can think of — blueberries, cranberries, apples, almonds and squash — would never get to your plate without the help of insects. No insects, no pollination. No pollination, no fruit.

Texas Study Points To A Longer Natural Gas Boom

A natural gas drilling rig just east of downtown Fort Worth, Texas. A new decade-long study finds the region's Barnett Shale formation has sufficient gas reserves to last another 25 years.

There are few things in life more joyful than discovering a giant oil or natural gas field in Texas. You're suddenly rich beyond your wildest dreams. When the scope and size of the natural gas reservoir in the Barnett Shale in North Texas first became apparent, there were predictions that the find would last 100 years.

Well, that was over the top. But University of Texas geology professor Scott Tinker, who designed and authored a new study of the Barnett Shale, says there's still a lot of gas down there, even after a decade of drilling.

The world's first space tourist is financing a project that aims to launch an American man and woman on a mission to fly by Mars in 2018.

Back in 2001, businessman Dennis Tito shelled out about $20 million to ride a Russian spaceship up to the International Space Station. Now he's unveiled a new nonprofit group called the Inspiration Mars Foundation.

Attack By Chondrite: Scientists ID Russian Meteor

Researchers who studied pieces of the meteor collected near Lake Cherbarkul say it was a common chondrite meteor. The largest of the 53 fragments was one centimeter in diameter. Photo provided by the Urals Federal University Press Service.

The meteor that caused at least 1,000 injuries in Russia after a startling and powerful daytime explosion one week ago has been identified as a chondrite. Russian scientists who analyzed fragments of the meteor, whose large size and well-documented impact made it a rarity, say that its composition makes it the most common type of meteor we encounter here on Earth.

Earth As Art: 'How Did Nature Do That?'

Carnegie Lake, Australia, 1999 Carnegie Lake in Western Australia fills with water only during periods of significant rainfall. In dry years, it is reduced to a muddy marsh. Flooded areas appear dark blue or black, vegetation appears in shades of dark and light green, and sands, soils and minerals appear in a variety of colors.

Satellites are powerful tools. They beam our TV signals, phone calls and data around the planet. They help us spy, they track storms, they power the GPS signals in our cars and on our phones. But they also send back striking, totally disarming images of planet Earth.

This set of images is all about showing off the "beauty of the Earth," says Lawrence Friedl, the director of NASA's Applied Sciences Program and the editor of a project called Earth as Art. "We want people to look at these images and say, 'How did nature do that?' "

Honey, It's Electric: Bees Sense Charge On Flowers

Adam Cole NPR

Originally published on Fri February 22, 2013 7:47 am

Flowers are nature's ad men. They'll do anything to attract the attention of the pollinators that help them reproduce. That means spending precious energy on bright pigments, enticing fragrances and dazzling patterns.

Now, scientists have found another element that contributes to flowers' brand: their distinct electric field.

Anne Leonard, who studies bees at the University of Nevada, says our understanding of pollinator-flower communication has been expanding for decades.

The Filibuster Solution, Or 'What If Honeybees Ran The U.S. Senate?'

Adam Cole NPR

Originally published on Tue February 19, 2013 10:08 am

Bees are democrats. They vote. When a community of bees has to make a choice, like where to build a new hive, they meet, debate and decide. But here's what they don't do: they don't filibuster. No single bee (or small band of bees) will stand against the majority, insisting and insisting for hours. They can't.

Bee biology prevents it.

If you've ever played around with one of those carbon or water footprint calculators, you probably know that meat production demands a lot from the environment — a lot of oil, water and land. (Check out the infographic we did on what goes into a hamburger last year for Meat Week.)

When it comes to treating a lazy eye, there's evidence that turning the lights off may help — if you're a kitten.

A study in the latest issue of Current Biology reports that kittens with a type of visual impairment known as amblyopia, or lazy eye, were able to regain normal eyesight after being plunged into total darkness for 10 days.

When the X-ray was invented, people clamored to get one. Not for any medical reason, but just to see what was typically hidden inside their bodies.

Something like that seems to be happening with DNA sequencing technology. First it was companies offering to sequence people's genomes. Now it's learning all about your microbiome, the collection of microorganisms living on and in your body.
