Scientists have discovered that the extinct megalodon shark was warm-blooded, as indicated by the isotopes in its tooth enamel. Their research suggests that the megalodon could maintain a body temperature about 13 degrees Fahrenheit warmer than the surrounding water, a significant difference compared to other contemporary sharks. A killer, yes. But analysis of tooth minerals reveals how the warm-blooded predator maintained its body temperature. Researchers have determined that the extinct megalodon shark was warm-blooded, able to maintain its body temperature higher than the surrounding water. However, the energy needed for this temperature regulation might have contributed to the megalodon’s extinction...

Water found in ancient Moon rocks might have actually originated from the proto-Earth and even survived the Moon-forming event. Latest research into the amount of water within lunar rocks returned during the Apollo missions is being presented by Jessica Barnes at the European Planetary Science Congress in London on Monday 9th September. The Moon, including its interior, is believed to be much wetter than was envisaged during the Apollo era. The study by Barnes and colleagues at The Open University, UK, investigated the amount of water present in the mineral apatite, a calcium phosphate mineral found in samples of the...

KIROVSK, Murmanskaya Oblast - The 30,000 inhabitants of this Arctic town in the middle of the vast Kola Peninsula pride themselves on being happy and hospitable. There are reasons for this: For an industrial town, the multicolored buildings look refreshingly pristine and the view is panoramic, especially this time of year, when the sun always hangs in the sky, except for an occasional dip behind the barren and breathtaking Khibiny mountains. But life hasn't always been so idyllic. Like hundreds of other outcroppings in Stalin's gulag system, Kirovsk was designed as a labor camp of death and detainment. It is...

With the help of a self-developed computer model, a team of researchers forecasted how apatite would have crystalized from cooling bodies of lunar magma early in the Moon's history. The model proved that the abnormally hydrogen-rich apatite crystals seen in many Moon rock samples may not have developed within a water-rich environment as previously though. "The mineral apatite is the most widely used method for estimating the amount of water in lunar rocks, but it cannot be trusted," said Jeremy Boyce of the UCLA Department of Earth, Planetary and Space Sciences in a statement. "Our new results show that there...
