It's hard to believe the landscape ever looked any different. But according to new research by UNLV climate scientists, the locations where those jungles exist today likely looked very different less than 9,000 years ago -- a blink of an eye by geologic standards.

Tourists today spend thousands of dollars to explore and enjoy the lush and thriving rainforests of Guatemala.

Emily Carter was interested in science from a young age. As she grew older though, and entered into her biology studies, she began to realize the problems for women in STEM fields.

The whole concept of an electromagnetic pulse sounds like science fiction, but they are very real.

No one enjoys boarding an airplane. It’s slow, it’s inefficient, and often undignified. And that’s without even getting into the ethical quandary of so-called gate lice, the anxious passengers who cluster at the gate before their group is called. But at least one part of the process doesn’t need to be disrupted. When it comes to shunting slow-moving passengers to the front of the queue, such as those requiring assistance or with small children, the airlines have it exactly right.

A team of researchers led from Norway used space-time geometry techniques to explore the factors that lead to a speedy take-off or an agonising delay on the tarmac.

Commercial airlines often prioritize boarding for passengers traveling with small children, or for those who need extra assistance—in other words, those likely to be slower to stow their bags and take their seats—before starting to board the faster passengers. It's counter-intuitive, but it turns out that letting slower passengers board first actually results in a more efficient process and less time before takeoff, according to a new paper in Physical Review E.

Dr. Ming-Wei Wu drives his son and daughter to the University of Nevada, Las Vegas, and escorts them to and from classes.

Molecules containing noble gases shouldn’t exist. By definition, these chemical elements — helium, neon, argon, krypton, xenon and radon — are the party poopers of the periodic table, huddling in the rightmost column and refusing to make molecules. Indeed, no one has ever seen any naturally occurring noble gas molecules on Earth. Earlier this decade, though, astronomers accidentally discovered one of these aloof elements in molecules in space.

When John Hiatt moved to southwest Las Vegas in 1976, the water level for his domestic well was 115 feet below the surface. A decade and a half later, it dropped to 140 feet.

Arizona’s Department of Environmental Quality is allowing a uranium mine operator to spray water laced with uranium and arsenic on the ground to keep dust down on its site, but it is considering the status of the mine’s permit.
