“The 2020 heat wave in the Russian Arctic shows how—even at high latitudes—really warm weather conditions can develop that can lead to fires that burn intensely and can grow to be very large,” says Isla Myers-Smith, an ecologist at the University of Edinburgh who studies the region but wasn’t involved in this new work.
Recently, Genge has been interpreting messages the space dust carries, not about its origins, but about its destination: Earth at different points in the planet’s history.
These neutrinos that Anita was searching for would be classified among the most energetic particles in the universe, which physicists believe are produced by the same processes that generate jets of charged particles called ultrahigh-energy cosmic rays.
But step into the Martian-like dry valleys and you’ll be treading on a bustling community of tiny organisms, like nematode worms and ultra-hardy water bears and mites.“Really, that's the charismatic megafauna of continental Antarctica,” says evolutionary ecologist Byron Adams of Brigham Young University, who is currently surveying life on the continent.
Now those records – plus millions of daily observations made by early explorers, people on whaling ships, cargo ships and lighthouses around New Zealand and the Southern Ocean before the 1950s – are needed by scientists trying to find out more about climate change.
Rather, these penguins, who were mummified by the cold, dry Antarctica environment, likely died from weather on the opposite end of the spectrum: two extremely rainy and snowy events that happened over the past 1,000 years, a new study finds.
