• Hundreds of hidden earthquakes found at Antarctica’s Doomsday Glacier

  Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near the marine edge of the Thwaites Glacier. Many appear to be glacial earthquakes caused when huge icebergs break off, capsize, and collide with the glacier. The surge in activity coincided with a period when Thwaites was flowing faster toward the ocean, hinting that changing ocean conditions may be destabilizing the ice.

• Researchers unveil sustainable spirulina solution to vitamin B12 deficiency

  Researchers have produced a form of Spirulina containing biologically active vitamin B12 at levels comparable to beef. By carefully controlling the light used to grow the algae, they overcame a major problem with conventional Spirulina, which mainly contains a form of B12 the human body cannot use. The carbon-neutral system could provide a more sustainable source of the essential vitamin.

• Australia’s red soil may be hiding a massive clean energy source

  Researchers have discovered that Western Australia’s iron-rich rocks can naturally generate hydrogen and that the process may be boosted to produce much larger amounts. If it can be scaled up, the vast formations beneath the Pilbara could become a major new source of low-emission energy for Australia and potentially the world.

• The next Cascadia megaquake could hit Oregon harder than expected

  The Juan de Fuca plate beneath northern Oregon appears to be shallower than previously estimated, potentially making shaking from a future Cascadia megathrust earthquake significantly stronger. Scientists also found a deep basin beneath Tillamook that could trap seismic waves and intensify the shaking even further.

• Ancient Egyptian princesses were buried with weapons. Their bones reveal why

  Weapons buried with ancient Egyptian princesses may have been more than ceremonial decorations. Researchers studying royal mummies from Dahshur found bone changes consistent with years of archery and other strenuous weapon use. Several women also showed evidence of healed injuries, suggesting surprisingly active lifestyles that may have included hunting or military training.
