The massive skull bones and horn plates of muskoxen do not prevent the formation of brain damage after continuous fierce fights
Arctic volcano caused ancient global cooling
Not a volcanic eruption in Greece, but a much larger eruption in Alaska led to global cooling about 3,600 years ago.

The history of Antarctica (almost) within reach
A lake discovered under the East Antarctic Ice Sheet may hold information about its 34-million-year history.
Precipitation influenced distribution of Arctic dinosaurs
Precipitation played a more important role than temperature in the distribution of dinosaur species in Late Cretaceous Alaska, researchers found.

Another giant iceberg calved in East Antarctica
Authorities from the U.S. and Australia report another “birth” of a more than 400-square-kilometer iceberg there, where an ice shelf first broke apart in March.
Atmospheric rivers led to ice shelf collapse
The trigger of the collapse of the two smaller parts A and B of the Larsen Ice Shelf was, according to the latest findings, warm and humid air currents.
Lots of ice, lots of penguins – and vice versa
Where there is still sufficient sea ice along the Antarctic Peninsula, Adélie penguin populations are also stable. Where it is now too warm, unfortunately not.
Do Antarctic fish ingest microplastics?
Two Swiss scientists are addressing the question by studying Antarctic fish and invertebrates for microplastics.
Not a fertilization effect caused less CO2 in ice-age atmosphere
During the ice ages, it was not iron-rich dust and its fertilizing effect that provided CO2 storage in the Antarctic Ocean, but other mechanisms.
Falkland Islands recognized as globally significant seabird hotspot
The Falkland Islands serve as a breeding ground for hundreds of thousands of penguins, albatrosses and other seabirds, and are now considered a Key Biodiversity Area for seabirds.

Cause of earthquake series near Antarctic Peninsula found
The series of earthquakes that occurred between August 2020 and February 2021 between the South Shetlands and the Antarctic Peninsula has been resolved thanks to new methods.
Greenland sharks — anything but voracious
The largest Arctic fish needs just a handful of food per day to survive.
Hunting ban helped the walrus on Svalbard
