On a basic level, it seems that most of the universe can be divided into two kinds of big objects: stars and planets.

For all this week, we are focusing on women who have unique and inspiring jobs. Yesterday, you met a captain from the Clark Country Fire Department. Today, we are introducing you to a scientist whose work will reach all the way to Mars.
No fantasy world is complete without a fire-breathing dragon. SpaceX founder Elon Musk even wants to make a cyborg version a reality, or so he tweeted April 25. But if someone was going to make a dragon happen, how would it get its flame? Nature, it seems, has all the parts a dragon needs to set the world on fire, no flamethrower required. The creature just needs a few chemicals, some microbes — and maybe tips from a tiny desert fish.
Research into the regeneration of eye tissue in embryonic frogs could support work to restore human tissue.
A UNLV scientist and her team have found that frog embryos can fully regrow their eyes after injuries, a breakthrough that may lead one day to the ability to orchestrate tissue regeneration in humans.
Xenopus laevis embryos of the African clawed frog, a species that had been used for decades to detect pregnancy in the United States, (only to be later released into U.S. waters after they were no longer needed in labs), has the capability to regenerate fully functioning eyes, according to researchers with the University of Nevada at Las Vegas.
Imagine solving prehistoric mysteries by sifting through the ashes of ancient volcanoes.

Pollen is in the air in Las Vegas — and that means allergy season is in full swing.
It's one of the biggest mysteries of recent human evolution. Roughly 70,000 years ago, Homo sapiens went through a genetic bottleneck, a period when our genetic diversity shrank dramatically. But why? In the late 1990s, some scientists argued that the culprit was a massive volcanic eruption from what is now Lake Toba, in Sumatra, about 74,000 years ago, whose deadly effects reduced our species to a few thousand hardy individuals. Now, new evidence suggests we were right about the volcano—but wrong about pretty much everything else.
Water may be more common than expected at extreme depths approaching 640 kilometres and possibly beyond -- within Earth's lower mantle, says a study that explored microscopic pockets of a trapped form of crystallised water molecules in a sampling of diamonds from around the world.
Early humans survived a massive volcanic eruption 74,000 years ago as well as flourished during the resulting climate change, finds a new study.

Diamonds are a geoscientist’s best friend — this is especially true for a group of researchers who recently found hard evidence that water exists deep within Earth’s mantle by examining diamonds from around the world.

To most of us, ice is just ice. But scientists have categorized no less than 16 types, created under different conditions and featuring different crystalline structures. Most of these have only been created in the lab, but now, geoscientists at the University of Nevada Las Vegas (UNLV) have discovered a type known as Ice VII (seven) locked inside diamonds. This marks the first time the substance has been directly detected in nature, and it suggests that the Earth's mantle is home to huge pockets of water.
