SoT 170: A Big Year For Zircon
More details on Philae's rough landings, and the future of\xa0the first probe to land on a comet.\xa0Professor Monica Grady's\xa0reaction to the landing, the\xa0sound of\xa0the landing, and\xa0the\xa0comet 'sings'.
When a pair of scientists found their experiment contaminated from the DNA Isolation kits they were using, they set out to\xa0see if other experiments were similarly contaminated.
Researchers at Australia's James Cook University have discovered tiny zircon crystals on Vanuatu. But surprisingly, they\xa0seem to have originally come from Australia.
Scientists have\xa0descended into\xa0one of the\xa0three mysterious craters that have formed\xa0this year in Siberia, onto a frozen lake. The most likely explanation for the craters is a "catastrophic destabilization of Arctic methane stores due to human-caused warming".
