That level of regeneration may be out of the question for humans right now, but at the University of Nevada, Las Vegas (UNLV), one lab team is researching the possibility of animal eye regeneration, and how that might impact human eyecare.

Nearly every one of Big Basin's old-growth redwoods survived the wildfire. As University of Nevada, Las Vegas biologist Drew Peltier observed in 2023, just three years after the blaze, "coastal redwoods are supremely fire-adapted … and they seem to be recovering."

A 2018 study from UNLV and the local nonprofit Tortoise Group estimated that more than 150,000 desert tortoises are being kept as pets throughout the Valley. Backyard breeding is a major driver of this overpopulation problem, and there simply aren’t enough people to house all of them. Ill-suited for the wild, roughly 1,000 of these captive creatures are displaced or put up for adoption annually.

Gardening and bird watching often go hand-in-hand with the feathered visitors bringing joy to many a British home, but experts say there are six things to avoid if you want to attract more avians.

Foxes are vital to ecosystems, helping reduce rodent and rabbit populations. However, they can also dig holes in yards, get into trash, tear up fencing, and steal fruits and vegetables from gardens. While they certainly are important, you may not want them in your yard all the time. Fortunately, there are ways to naturally and humanely deter them—here, we spoke with experts about a few go-to methods.

Since mid-November, bird enthusiast Skye Marsh of Las Vegas had been hoping to get the call she received Wednesday afternoon. The lost toucan, appropriately named Sam, had been found.

Birding experts say your outdoor space could be missing several key elements.

Las Vegas is not a good environment for a toucan to be in the wild with its too-hot summers and cold winters, said Donald Price, a professor and biologist at the University of Nevada in Las Vegas who studies how winged animal species adapt to different environments.

Rising temperatures, diminished rainfall and steadily increasing usage have taken a serious toll on the Colorado River and the water it contains. Some question whether the Las Vegas Valley will have enough water to last into the future.

A trio of Nevada professors is working with NASA to investigate what drives life deep underground, hoping to create a better understanding of how ecosystems can thrive miles beneath the surface of Earth— and potentially on other planets.

The Nevada team, which will include researchers from the Desert Research Institute, the University of Nevada, Reno, and the University of Nevada, Las Vegas, will collect samples from underground sites in Nevada and the southwest to study how microbial communities use radiation byproducts to survive.

The cute acrobats are fun to watch—that is, until they dig through your flower beds, damage your tree trunks, or nest in your attic. Here's what you can do to get rid of squirrels on your property without harming them.
