Acellular Players In The High Cryosphere: Diversity, Function And Activity Of The Global Supraglacial DNA Viruses
Supraglacial environments mainly consist of four main types of habitats for microbes and viruses, including snow, ice, meltwater, and cryoconites (the granular sediment on glacier surfaces).

Cellular Antifreeze Developed In Animals Far Earlier Than We Thought
The globe was hot and humid. The sea was teeming with life. Early squids, eel-like fish and sea worms hunted smaller animals. Above ground, however, nothing stirred. The animals had […]

Away Team Update: DLR TRIPLE-IceCraft Expedition To Antarctica Part 2
At the time of our arrival at Neumayer Station III. Technically it is morning, but the long journey has messed up my internal clock.

Away Team Update: DLR TRIPLE-IceCraft Expedition To Antarctica Part 1
Some regions on Earth are as mysterious as distant celestial bodies – but equally explored. These include subglacial lakes in Antarctica. These lakes lie under a permanent layer of ice, […]
