Brian Hedlund and Ariel Friel collect microbes living for tens of thousands of years in the subsurface of the earth. By studying these microorganisms, they hope to gain clues about potential life on Mars and other planets.

“The butterfly and the buckwheat” may not sound like a match made in heaven, but the Spring Mountains dark blue butterfly depends heavily on this yellow, flowering plant from birth until new eggs are laid the following season.

Martin Schiller’s research lab at UNLV is creating far more than just experiments. The research completed inside the Schiller Laboratory of Applied Bioinformatics has led to Schiller’s Heligenics, a startup that could help genetics testing companies shine a light on undiagnosed diseases.

Some bears hibernate in hollowed out tree-trunks. Some take a months-long rest beneath thick brambles and brush. Others dig into the hills to forge snug dens. And still others discover caves to hide away from the biting winter chill.

The public outcry over the selective thinning of beautiful — but non-native — pine trees from Oak Opening Preserve Metropark is being tempered by science that now shows the controversial Metroparks Toledo decision from years past is paying off.

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.

Diamonds, the super-strong and brilliant crystals of carbon atoms produced under the Earth’s crushing pressures, are typically valued for their beauty and durability. But scientists also value them for another reason: They contain all kinds of hidden messages about the Earth’s mantle. You just need the right tools to read them.

A new report published today in Science suggests that pockets of liquid water may exist up to 500 miles beneath Earth’s surface—far deeper that previous estimates. This conclusion was reached after scientists discovered a rare form of crystalized water known as ice VII in diamond samples recovered in Africa and China. These ice VII samples are the first time this form of crystalized water has been seen in nature and led the International Mineralogical Association to declare ice VII as a new type of mineral.

X-ray spectroscopy helped to investigate the diamond crystals collected on the fields in Africa, China, Zaire and Sierra Leone, and to find in them microinclusions ordinary water ice, but in a rare cubic phase of ice VII. The find, which scientists report in an article published by the journal Science, may lead to a reassessment of our ideas about the amount of water hidden in the bowels of the Earth.

Trapped in the rigid structure of diamonds formed deep in the Earth’s crust, scientists have discovered a form of water ice that was not previously known to occur naturally on our planet.

A team of researchers from the U.S., China and Canada has found evidence in diamonds of free-flowing water in the boundary between Earth's upper and lower mantle. In their paper published in the journal Science, the group describes analyzing inclusions in diamonds spewed from volcanoes and what they found.

The Curiosity rover made big news in late 2014 when it first detected organic matter on Mars. But in detailed studies of the sites in Gale Crater studied by Curiosity, called Yellowknife Bay and Sheepbed Mudstone, the concentration of organic molecules were much lower than scientists had expected.
