  • Missing link in metal physics explains Earth’s magnetic field

    Earth’s magnetic field is crucial for our existence, as it shields the life on our planet’s surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth’s core. Iron is a metal, which means it can easily conduct a flow

  • Low level inspection flight over Holuhraun lava field, Iceland

    Comprehensive cross-section measurements from air from December 30, 2014 and January 21, 2015 show that the lava field has thickened substantially during these three weeks and that the volume of the lava field is now little less than 1.4 km³. The flow of magma, dur

  • Long series of droughts doomed Mexican city 1000 years ago

    Archaeologists continue to debate the reasons for the collapse of many Central American cities and states, from Teotihuacan in Mexico to the Yucatan Maya, and climate change is considered one of the major causes.A University of California, Berkeley, study sheds new ligh

  • The winners and losers of ocean acidification

    The population balance of some marine ‘pests’ could be drastically changed as the world’s oceans become increasingly acidic.Populations of certain types of marine organisms known collectively as the ‘biofouling community’ – tiny

  • New climate change projections for Australia

    CSIRO and the Bureau of Meteorology released climate change projections for Australia that provide updated national and regional information on how the climate may change to the end of the 21st century.The projections are the most comprehensive ever released for Austral

  • Swarm of scientific microprobes to the clouds of Jupiter in 2030

    A swarm of tiny probes each equipped with a different sensor could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere, according to a recently presented concept in International Journal of Space Scie

  • Fluorescent blue, harmful algal bloom along the Hong Kong shores

    A bioluminescent algal bloom created by Noctiluca scintillans, commonly known as Sea Sparkle, is turning Hong Kong's seashores into a spectacular and disturbing sight this week. Scientists say the fluorescent blue glow is an indicator of a harmful algal bloom. Altho

  • 67P – The violent birth of a comet

    The electric comet idea forces us to consult the astronomical testimony of our earlier forebears, where independent accounts, told with different words and different symbols in different parts of the world, convey a story of planetary catastrophe. Watch Update #1: The R

  • A 3D view of the age and structure of the Greenland Ice Sheet

    Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first-ever comprehensive map of layers deep inside the Greenland Ice Sheet. This new map allows scientists to determine the age of lar
