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.

Coming out of the last glacial period, there was a sudden climate reversal observed throughout the tropical and subtropical regions of the Earth. The cause of these changes during this interval so enigmatic, so much so, the interval was informally referred to as the “Mystery Interval.” Many large shifts in climates in the past seem to be synchronized with climate in the poles as expressed in ice core records.

It’s a beekeeper’s nightmare: She lifts the lid on her carefully tended hive and is greeted with a whiff of rotting flesh. Further inspection finds that the young bees of the colony, who should be plump, pearly-white larvae, have melted into a puddle of brownish goo at the bottom of their cells. This colony is infected with American foulbrood disease—most likely a death sentence.
