The question of whether Mars ever supported life has captivated the imagination of scientists and the public for decades. Central to the discovery is gaining insight into the past climate of Earth’s neighbor: was the planet warm and wet, with seas and rivers much like those found on our own planet? Or was it frigid and icy, and therefore potentially less prone to supporting life as we know it? A new study finds evidence to support the latter by identifying similarities between soils found on Mars and those of Canada’s Newfoundland, a cold subarctic climate.

Local and national public-interest groups, as well as Havasupai Tribe members, delivered more than 17,000 petition signatures to Gov. Katie Hobbs today urging her to use her authority to close the Pinyon Plain uranium mine that threatens the waters of the Grand Canyon and the Havasupai Tribe.

Clark County School District teachers took a field trip on Wednesday—not with students, but with UNLV professors. They went to Late Night Trailhead to check out some of the rock formations unique to the Las Vegas Valley and to find ways to add new and exciting lessons that engage students on top of their existing curriculum.

Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists at Scripps Institution of Oceanography at UC San Diego and colleagues have analyzed on Earth.

When a meteorite smashed into Mars eleven million years ago, pieces of the Red Planet hurtled into space—and some of them landed on Earth in the form of meteorites, depositing unparalleled evidence of the planet’s makeup. Now, scientists at Scripps Institution of Oceanography at UC San Diego have released a report after their detailed study of the Martian meteorites collected from locations across the world, including Africa and Antarctica.

Three UNLV professors are working on an iron-production method that doesn’t generate carbon emissions, part of an effort to clean up one of the world’s dirtiest industries.

Two unknown people destroyed an ancient rock formation in Lake Mead National Recreation Area in Nevada, USA, in just a few seconds. A video showing the two men in the act has been circulating on X (formerly Twitter) since the beginning of April. The national park authorities have therefore initiated an investigation and are asking the public to help find the perpetrators.

A video posted to social media this month captured two men destroying ancient rock formations at Lake Mead National Recreation Area in Nevada. National park rangers are asking for the public’s help in identifying the visitors, who could face federal charges for vandalizing protected land.

A push for nuclear power is fueling demand for uranium, spurring the opening of new mines. The industry says new technologies will eliminate pollution from uranium mining, but its toxic legacy, particularly in the U.S. Southwest, leaves many wary of an incipient mining boom.
