Mystery Crater In Nicaragua

Mystery crater: A 40-foot crater has appeared in the ground near Managua airport. Nicaraguan authorities said the hole was caused by a meteorite that broke off from the passing Pitbull, or 2014 RC, asteroid. But NASA officials said that was unlikely, because such a strike would have produced an enormous fireball streaking across the sky, yet nobody reported seeing anything […]

Drastic climate change

An analysis of isotopes in marine fossils from around the world yielded the most complete record of Earth’s temperatures yet—and showed that the planet is heating up at a rate unprecedented in the past 11,300 years. Scientists say that if it weren’t for greenhouse gas emissions, a cooling trend that began 5,000 years ago after a shift in the planet’s […]

Destroying Antarctica While Attempting To Save It

Destroying Antarctica

Are the scientists working to save Antarctica’s fragile ecosystem inadvertently contributing to its destruction? Could they possibly be Destroying Antarctica? A new study has linked a chemical used in flame-retardants—called polybrominated diphenyl ethers (PBDEs)—that is contaminating the Antarctic environment to Australia’s Casey research station. Researchers found that dust and treated wastewater at the station contained PBDEs and another chemical that […]

A new water world

Saturn’s ice-covered moon Enceladus could harbor a warm-water ocean beneath its frozen surface, opening up new possibilities for life beyond Earth. Enceladus has fascinated astronomers since 2005, when NASA’s Cassini probe caught geysers on the moon’s south pole spewing out plumes of salty water. Water that is thought to have originated in an ocean buried beneath the moon’s 25-mile-thick ice […]

Antarctic Fish Have Ice In Their Veins

Scientists have revealed that some fish that thrive in the freezing cold waters of the Antarctic actually have ice in their veins. A protein in their system called notothenioids not only keep the fish from freezing to death, but also keeps ice crystals in their veins. Although the ice crystals would melt at temperatures just slightly above freezing, the fish […]
