Citlally Lopez is under the microscope, as all eyes are on the Las Vegas native for her research into finding a cure for the second leading cause of death in the world.

Humans began to alter environments long before records were kept of the things that lived in them, making it difficult for scientists to determine what healthy ecosystems should look like. The researchers have now shown that the recent fossil record preserves an authoritative snapshot of marine environments as they existed before humans.

As we plunge into Earth’s sixth stage of mass extinction (that we are aware of), biologists looking to conserve and restore ecosystems that have been stripped of plant and animal life can face a pretty daunting task. However, help is on the way in the form of some of the ocean’s worms, mollusks, and crabs. A study published July 11 in the journal PeerJ, finds that fossils from these groups are actually preserved in the fossil record in proportion to their diversity, making for a solid source of information about past ecosystems.

Around 1,800 miles beneath your feet lies a giant, blazing-hot ball of metal. It's the innermost part of our planet, Earth's core. It has a profound impact on your life, though none of us can even glimpse this impossibly remote, hostile place. The core is about the size of Pluto, yet scientists found that distant world in our solar system nearly a century ago, before discovering proof of the core.

Although disposable storage bags are so handy, it can be wasteful to use a zip-top plastic baggie just once and then throw it away. But, in the name of being environmentally conscious, is it actually safe to wash and reuse the plastic bags?

Swatting is a form of domestic terrorism that is sometimes deadly and has become more widespread in the US, according to a March report from Hal Berghel, a computer science professor at University of Nevada, Las Vegas.

Re “Titan submersible implosion: another safety lesson learned through tragedy” (Editorial, June 24): Despite our ability to adapt and our incredible intelligence, humans can’t live in the extreme conditions of the deep ocean. The use of an experimental submersible that was not tested with the full rigor necessary to operate it as a commercial vessel should never have been allowed.

High schoolers could read about the Great Unconformity in a geology textbook, or they could stand on a trail on Frenchman Mountain, notice that the rocks look different and wonder why.

For the first time, an international team caught a rapidly spinning pulsar that had just finished snacking on its companion star and was ready to destroy it with strong wind and radiation.

Questions still remain after a missing Titanic submersible suffered a 'catastrophic implosion' and left five people dead.

All stories start somewhere – even the incomprehensibly vast expanse above us has a beginning. Scientists have long studied the cosmos, searching for answers to the “how’s” and “why’s” of life, and that effort continues to this day.

The report of an alien sighting at a Las Vegas home made headlines around the world. The reported sighting was triggered when a mysterious fireball was seen falling from the sky. That's when numerous calls came to 911 with one Las Vegas caller claiming an alien was in their backyard. Astrophysicist Jason Steffen says it was a meteor, not a spaceship, and it probably landed in the ocean. Inside Edition's Jim Moret returned to the Las Vegas home that reportedly spotted the aliens.
