As Climate Warms American West, Iconic Trout In Jeopardy

Native Westslope cutthroat trout and bull trout swim in the cool waters of the Flathead River near Glacier National Park, Montana.

In the mountain streams of the American West, the trout rules. People don't just catch this fish; they honor it. And spend lots of money pursuing it.

But some western trout may be in trouble. Rivers and streams are getting warmer and there's often less water in them. Scientists suspect a changing climate is threatening this iconic fish.

I joined two such scientists from the U.S. Geological Survey as they drove up a mountain road in Montana, in the northern Rockies, a place dense with stands of Douglas fir and aspen trees and braided with mountain streams.

Could Hunger Make Us More Charitable?

Researchers have a hunch that because we often had to share food to survive, we're inclined to be more interested in giving when we're hungry.

Hunger can make people emotional, that's for sure. Some people get "hangry" when their blood sugar levels drop and their irritability rises. Others get greedy.

But new research suggests that we may have another, innate response to hunger: a desire to encourage others to share what they have.

Why Can We Taste Bitter Flavors? Turns Out, It's Still A Mystery

The first taste of an olive can be a bit shocking. But eventually, many of us start to enjoy bitter fruits, nuts and beverages.

For most of us, bitter foods aren't love at first bite. (Not convinced? Just watch the little girl in the video above taste an olive for the first time.)

But after a few espressos or IPAs, most of us warm up to bitter flavors and eventually throw our arms in the air, like the little girl in the video, declaring, "Yes, I love bitter foods!"

Why Typhoon Haiyan Caused So Much Damage

This map from the NOAA Environmental Visualization Laboratory shows the amount of heat energy available to Typhoon Haiyan between Oct. 28 and Nov. 3. Darker purple indicates more available energy. Typhoons gain their strength by drawing heat out of the ocean. The path of the storm is marked with the black line in the center of the image.

The deadly typhoon that swept through the Philippines was one of the strongest ever recorded. But storms nearly this powerful are actually common in the eastern Pacific. Typhoon Haiyan's devastation can be chalked up to a series of bad coincidences.

'Ferrari Of Space' Crashes And Burns In Earth's Atmosphere

An artist's rendition of the GOCE satellite shows the craft in its orbit around Earth. After four years of studying oceans and gravity fields, GOCE re-entered the atmosphere over the Southern Atlantic Ocean Sunday night.

More than a ton of advanced electronics, including an ion engine and sensors that help detect variations in gravity, crashed into Earth's atmosphere Sunday night, when the European GOCE satellite ended its four-year mission. Most of the 2,425-pound craft disintegrated when it re-entered the atmosphere over the South Atlantic Ocean; about 25 percent did not.

Lessons In Leadership: It's Not About You. (It's About Them)

Ronald Heifetz draws on his training as a psychiatrist to coach aspiring leaders at Harvard's John F. Kennedy School of Government.
Ben de la Cruz NPR

Originally published on Mon November 11, 2013 6:15 pm

Ronald Heifetz has been a professor of public leadership at Harvard's Kennedy School for three decades, teaching classes that have included aspiring business leaders and budding heads of state. Each year, he says, the students start his course thinking they'll learn the answer to one question:

As leaders, how can they get others to follow them?

Heifetz says that whole approach is wrong.

Lighting Up The Investigative Path With Polonium-210

Palestinian leader Yasser Arafat boards a helicopter in Ramallah, the West Bank, for the start of his journey to a hospital in France on Oct. 29, 2004. He died 2 weeks later.

With a Swiss forensics investigation pointing to polonium-210 as a possible cause of Yasser Arafat's death, the radioactive element is back in the news.

Confirming whether the Palestinian leader died from an assassination attempt will be difficult, given polonium's short half-life and the fact that Arafat has been dead nine years, science writer Deborah Blum says.

Whatever happened to Arafat, polonium does have a deadly history.

Can We Eat Our Way To A Healthier Microbiome? It's Complicated

While no one's sure which foods are good for our microbiomes, eating more veggies can't hurt.

When our colleague Rob Stein got his microbiome analyzed recently in the name of science journalism, we were totally fascinated.

As Stein noted, it may be possible to cultivate a healthier community of bacteria on and inside us by modifying our diets.

Stein was advised to eat more garlic and leeks for his. But we wondered: Are there other foods that promote a healthy microbiome in most people?

Which Is It? Hurricane, Typhoon Or Tropical Cyclone?

What's the difference between a hurricane, a typhoon and a cyclone? Nothing more than location.

As Super Typhoon Haiyan slams into the Philippines, we here at the Two-Way found ourselves revisiting old ground about the nature of tropical storms. In case you need a refresher (as we did), here is the lowdown:

Astronomers Find Bizarre 'Lawn Sprinkler' Asteroid

These NASA/ESA Hubble Space Telescope images reveal a never-before-seen set of six comet-like tails radiating from a body in the asteroid belt designated P/2013 P5.

Astronomers using both ground- and space-based telescopes have discovered a new kind of asteroid that sports not one, but six comet-like tails, and has been described as looking something like a rotating lawn sprinkler.

P/2013 P5 was first spotted with the Pan-STARRS 1 telescope at the top of Haleakala volcano in Maui, Hawaii, in August and then followed up with more detailed observations using the Hubble Space Telescope.

How Tall Is The Washington Monument? Surveyors Take To The Top

National Geodetic Survey crew members Roy Anderson, left, and Steve Breidenbach set up survey equipment used to measure the height of the Washington Monument.

Originally published on Fri November 8, 2013 12:23 pm

The National Geodetic Survey doesn't often get the opportunity to take detailed measurements of the massive stone obelisk that sits in the middle of Washington, D.C.

But a 2011 earthquake in nearby Mineral, Va., damaged the Washington Monument enough that to repair it, the tower had to be wrapped in scaffolding. That gave surveyors access to the very top of the structure.

The Myth of the Woolly Bear

Legend holds that the length of a woolly bear caterpillar's color bands can be used to forecast how severe the winter weather will be. The myth dates back to colonial American folklore but was popularized by a 1948 study. SciFri finds out if there's any truth to the lore, and what the caterpillar's fuzzy bristles are really used for.
