Two Boise State University professors have received a $15,000 grant from the National Endowment for the Arts to study the relationship between three western universities and their local arts scenes.

An Idaho woman is studying the migration patterns of a rare bird in Central America. The three-wattled bellbird makes bell-like calls, and those sounds can travel half a mile. Some experts believe it’s the loudest bird in the world.

Driverless cars are one step closer to joining Idaho citizens on the roads.

By a one vote margin, the Idaho Senate passed a bill allowing companies to test self-driving cars in Idaho. The bill also sets some regulations and guidelines aiming to improve safety.

Senate Transportation Committee Chairman Sen. Bert Brackett told lawmakers Thursday he hopes the bill will attract innovative businesses to Idaho.

But the plan's insurance and liability requirements faced bipartisan opposition on the floor.

Jeffrey Johnson got quite a wakeup call this week. The assistant professor of geosciences at Boise State University is working in Pucon, Chile on a Fulbright grant to study volcanoes. He was just ten miles away when the Villarrica volcano had a large eruption Tuesday morning.

Johnson's work includes listening to low frequency sounds that volcanoes make. Here’s the low-frequency sound his sensors recorded during this week's eruption; the sound is normally too low for us to hear, so it's been sped up:

A Boise State University professor wants to make it easier to decide whether it's worth it to spend a little more on organic produce, or purchase the cheaper non-organic option.

"Eighty percent of American grocery stores now sell organic food and people have to decide for themselves is this worth it to buy to feed myself and my family?" says Cynthia Curl. "We don't have a lot of guidance to give to those people and so I think it's a really important thing to study."

NPR social sciences correspondent Shankar Vedantam is speaking Thursday in Ketchum at the Sun Valley Center for the Arts.

Vedantam regularly connects public radio listeners to scientific studies that show how unconscious factors can influence people without their awareness. Vedantam has written a book on the topic and calls these subconscious drivers the “hidden brain.”

Attending state-funded prekindergarten substantially reduces the likelihood that students will end up in special education programs later on, according to a new study by researchers at Duke University.

A Boise State professor is looking for clues about Earth's origin by studying planets around distant stars.

Brian Jackson is an assistant professor in Boise State’s Department of Physics. He’s using a $271,000 grant from NASA and data from the Kepler space observatory to study planets that are very close to their host stars.

An Idaho State University study has found most high school football players are wearing helmets that don't fit and aren't property maintaining the inflatable lining inside their helmets.

The University’s research finds nearly 98 percent of its participants played football in a helmet that required regular inflation of the liner, 43 percent of those respondents said they’ve never re-inflated their helmet liners.

According to researchers at Washington State University, shoppers may be more likely to accept bad customer service from a company if they know that company supports causes they agree with.

The College of Idaho has received a $2.45 million grant spread over five years for biomedical research.

The school in southwest Idaho in a statement Monday says that about a third of the money will be used to investigate the medical properties of sagebrush.

A similar amount will be used to research small molecule inhibitors that could be used to fight pathogenic microorganisms.

The school says the rest of the money will be used for other research projects.

The money comes from the National Institutes of Health's IDeA Network of Biomedical Research Excellence.

New research could have implications for cattle and sheep grazing in the habitat of a ground-dwelling bird that environmentalists say needs federal protection across the Rocky Mountain region.

A study published in the December issue of Wildlife Biology examines the relationship between nesting success by the greater sage grouse and the height of grass nearby.

Environmental groups including WildEarth Guardians say the study is cause for concern about livestock grazing in sage grouse habitat. Others say grazing can improve habitat for sage grouse.

Scientists have found that, contrary to what many people think, killing wolves does not always reduce attacks on livestock.

Researchers at Washington State University found that for every wolf killed in Idaho, Montana and Wyoming over the past 25 years, there was a 5 percent increase in the sheep and cattle killed the next year. Livestock kills only started going down after overall wolf numbers were reduced by more than 25 percent.

The study was published Wednesday in the journal PLOS One.

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.

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.

Buzzworthy Breeding To Bring Back Bumble Bees

Aug 10, 2014

Some scientists are going to great lengths to help the agreeable Western bumble bee make a comeback.

Research geologists have just finished a field trial to test a less invasive way to complete seismic hazard surveys.

A fungus found in Chobani yogurt produced at its Twin Falls facility last year that led to a voluntary recall was more virulent than first thought.

In August and September 2013 more than 200 people were made sick by the Greek yogurt after a strain of fungus called Mucor circinelloides was detected in the product.
