The discovery of a mammoth skull near eastern Idaho’s American Falls reservoir recently made national headlines. But scientists' work on the mammoth has just begun.

A portion of a mammoth skull and tusk have been uncovered in southeastern Idaho near American Falls Reservoir.

Experts estimate the mammoth lived 70,000 years ago and was about 16 years old when it died.

The bones have been taken to the Idaho Museum of Natural history at Idaho State University in Pocatello where they will eventually be put on display.

The discovery of the bones on Oct. 18 by a volunteer with the U.S. Bureau of Reclamation followed heavy rains in August that caused additional erosion in the area.

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.

Antibiotics are ubiquitous in modern human life. Along with their well-known medical applications, they also are routinely used in agriculture, including our increasingly industrial production of meat.

But as resistant strains of bacteria continue to emerge, health authorities around the world are growing alarmed at the increasing impotence of antibiotics to fight disease. In fact, they worry we are on the verge of a total breakdown in the overall usefulness of these drugs. It’s a scenario of horrifying scope to those who understand the implications for human health.

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.

A skeleton that's about 9,000 years old is giving up a few of his secrets today. Monday, scientists who have a new book about the ancient remains found near Kennewick 18 years ago spoke to the press.

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.

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.

A swarm of central Idaho earthquakes that rattled Challis residents for more than a month appears to be dying out.

But seismologists say five portable seismographs have provided new information about the area that saw a sequence of quakes up to 4.9 in magnitude, peaking in mid-April.

Mike Stickney with the Montana Bureau of Mines and Geology based in Butte, Montana, says the earthquakes are occurring on a northwest trending zone on the west side of the Salmon River.

A disease-causing fungus thought to be confined to the deserts of the U.S. Southwest has been discovered in soil samples from eastern Washington.

Tuesday morning, Boise State University students will speak with astronauts aboard the International Space Station. They’ll get to ask the crew 20 questions. It’s all part of BSU’s Space Symposium.

All semester, BSU Space Broncos have been engaging with NASA, chatting online and taking part in the space agency’s research and programs. That work is culminating with a live chat with NASA astronauts Steve Swanson and Rick Mastracchio.

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.”
