The fossilized, spherical eggs belong to a previously unknown dinosaur species and were found packed with calcite crystals. They were unearthed in the Qianshan Basin in East China's Anhui province.

Nearly 7,000 years ago during the late Neolithic, or New Stone Age, a local farming community may have gathered in this circular building, although its true purpose is unknown.

The coffin, carved from pink granite, was crafted for an official named "Ptah-im-wea," who, according to the hieroglyphs inscribed on it, lived during the time of Ramesses II (reign circa 1279 B.C. to 1213 B.C.) and managed a temple that Ramesses II had built at Thebes (modern-day Luxor).

So far, the results have been shown only in mice. But if follow-up studies show similar trends in humans, that could eventually lead to treatments for metabolic disease and obesity, said senior author Ivaylo Ivanov, an associate professor of microbiology and immunology at Columbia University Vagelos College of Physicians and Surgeons.

As the sun advances through its regular 11-year solar cycle, electromagnetic activity on the star's surface gets more and more chaotic. This turbulence inevitably leads to the appearance of sunspots — dark, planet-size regions that form in the sun's lower atmosphere as a result of intense magnetic disturbances. To most visible-light telescopes, sunspots appear black. But why do they look this way, and are they really black?

The findings could potentially reveal the existence of diamond rain on ice giants in our solar system and explain why these frigid worlds have such strange magnetic fields. The laser-blasting technique could also lead to more Earthly applications.
