A new study out of Canada reveals a surprising side-effect that hunting may have on wolves.
Researchers wanted to compare the hormone levels in wolves that often deal with hunters’ fire, versus wolves that are hunted very little. They were able to measure levels of progesterone, testosterone and the stress hormone cortisol by looking at samples of wolf hair from different parts of northern Canada.
Could there be plate tectonics on other worlds? One former Idaho scientist thinks it’s possible. Until now, the movement of pieces of a planet’s crust was found nowhere else in the universe except Earth.
It was the late 1990s and University of Idaho planetary geologist Simon Kattenhorn was looking at one of Jupiter's moons named Europa. NASA’s Galileo orbiter took the pictures of it. Using those images, Kattenhorn discovered something remarkable.
Most Idaho kids went back to school this week, meaning for many, a return to school lunches. Food in public schools has changed significantly since new federal nutrition guidelines were passed in 2010.

The northern arm of the Rocky Mountains is sometimes called "the crown of the continent," and its jewels are glaciers and snowfields that irrigate large parts of North America during spring thaw.
But the region is getting warmer, even faster than the rest of the world. Scientists now say warming is scrambling the complex relationship between water and nature and could threaten some species with extinction as well as bring hardship to ranchers and farmers already suffering from prolonged drought.
It might seem like fire season is as bad as it’s ever been. But there’s a group of researchers who question that prevailing wisdom.
Three fresh science papers from separate institutions each makes the case that today's forest fires in the West burn less than in historical times. One of the co-authors is Dominick DellaSala, chief scientist at the Geos Institute in Ashland, Oregon.
More Idaho babies are being born outside of marriage than ever before, and the state's marriage rate is at a 60-year low, that's according to a recent report from the Idaho Department of Health and Welfare.
Fire season has come alive in the Northwest. On Monday, 20 homes in Idaho's Sun Valley area were briefly under evacuation when a fire broke out in a nearby canyon. A 5,000-acre fire north of Wenatchee, Washington, continues to threaten houses in the area.
Fires can be devastating to people's lives. But according to new research, at least certain types of forests recovery fairly quickly.
Most of the people who use the Boise Greenbelt have a college degree. And last year, more people used it on weekdays. Those are two big conclusions from two years’ worth of surveys on the 45-year-old trail system.
Jaap Vos is director of the Community and Regional Planning Program at Boise State University. BSU has done surveys on the Greenbelt two years in 2012 and 2013.
Many parts of the U.S. have been getting warmer over the past several decades, and also experiencing persistent drought. Wildlife often can't adjust. Among the species that are struggling is one of the American West's most highly prized fish — the cutthroat trout.
In springtime, you can find young cutthroats in the tiny streams of Montana's Shields Basin. Bend over and look closely and you might see a 2-inch fish wriggling out from under a submerged rock — the spawn of native cutthroats.

This week, scientists at the Smithsonian's National Museum of Natural History will start unpacking some rare and precious cargo. It's something the Smithsonian has never had before — a nearly complete skeleton of a Tyrannosaurus rex.
Geologists plan to install three portable devices known as seismometers or seismographs in the Challis area in central Idaho to help experts better understand a recent flurry of earthquakes.
The U.S. Geological Survey has recorded a sequence of quakes rumbling the area, the largest of which was a 4.9-magnitude quake on Saturday which shook pictures off walls. Challis residents also felt earthquakes above 4.0-magnitude on Monday and April 10.
The chemical BPA, or bisphenol A, is commonly found in plastics, soup cans, and store receipts. Scientists continue to study how the chemical affects people. New research from the University of Idaho may sound a cautionary note for humans.
Gordon Murdoch is an associate professor of physiology at the University of Idaho. He focused on fetal heart development in rhesus monkeys.
For the study, pregnant monkeys were fed fruit containing BPA. “Our question was did it affect the genes in the fetal heart?” he asked, “And to our surprise and dismay, it did.”
