The effects of global climate change are being felt in the West’s continuing drought, according to a panel discussion at UNLV last week. Wildfires have increased over the last several years, something one of Colby Pelligrino’s mentors told her years ago would show that climate change is legitimate.

While most people can appreciate the beauty of the grasslands and rocky canyons of Northern Arizona, the land holds a special meaning for Ka-Voka Jackson.

Ka-Voka Jackson wants to replace invasive plants with native ones at the Glen Canyon National Recreation Area.

In a remote canyon off the northern reaches of Lake Powell, a fourwing saltbush is growing deep roots as part of Ka-Voka Jackson's experimental plots of native plants. The silvery, sea-green shrub is joining grasses and succulents in Jackson's efforts to remedy ravenna grass infestations that threaten native flora and fauna in the sacred ancestral lands of her tribe and others around the Colorado River.

A team of scientists has discovered a new crystal form of DDT that is more effective against insects than the existing one. Its research, which appears in the journal Angewandte Chemie, points to the possibility of developing a new version of solid DDT—a pesticide that has historically been linked to human-health afflictions and environmental degradation—that can be administered in smaller amounts while reducing environmental impact.

A thaw is underway in Russia, and it has nothing to do with presidential politics. Inside a cave in Russia's Ural Mountains, where Europe and Asia meet, a team of UNLV researchers has found evidence of steady warming since the end of the last ice age.

Maybe you've heard about the permafrost that is proving not so permanent in the world's colder places.

A dry wash cuts through rolling hills dotted by desert plants at Lindsay Chiquoine’s research site near Lake Mead, but the only scenery that seems to interest her is right at her feet.

A week full of exploration and discovery is underway with more than 40 educational events throughout the Las Vegas Valley as part of the Science & Technology Festival. Hands-on exhibits, debates and tours of various facilities are scheduled, even an appearance by a creator of infamous “Star Wars” vehicles on May the Fourth.

Las Vegas is known for demolishing most of its past, at least above ground.

The earth remains chock full of prehistoric relics. Now, for the first time in years, a key find is in public hands.

UNLV researchers are excavating a remote undisclosed site in Nye County after remains of a Columbian Mammoth were discovered. For the past five months, a team of faculty and students at UNLV have made the two-hour trip to learn more about the discovery of intact mammoth tusks dating back more than 20,000 years.

UNLV has named Eric Chronister, professor and former chair of chemistry at the University of California, Riverside, as the new dean for the College of Sciences, effective July 1. Chronister replaces sciences professor Stan Smith, who served as acting dean for the past year.
