Meet the Penguin MisfitsScience | The Biological World Looks are important for Adelie penguins, but they may not be as critical for breeding as biologists previously thought. New research shows Adelie penguins with unusual coloring still manage to breed successfully, contrary to what biologists had predicted. Aug

Coldest, Driest, Saltiest Antarctic Soils Might Be Inhospitable To LifeScience | The Biological World Some Antarctic soils might be the only environments on Earth microbes can't colonize, a finding that goes against scientists' expectations of our planet's habitability. Most scientists assume microbes can inhabit every environment on Earth, given enough time, but new research finds that some of the coldest, saltiest, and driest soils in the Transantarctic Mountains show no signs of viable microbial life.

Cruising for MollusksScience | The Biological World Scientists are going to the ends of the Earth to discover all they can about an obscure group of sparkly, worm-like mollusks. There's lots of these critters living on the seafloor surrounding Antarctica, but they're not easy to get at and only a few scientists are studying them. Mar

Charting a Genetic Sea ChangeScience | The Biological World Scientists are mapping the coastline of ancient Antarctica using DNA from underwater invertebrates alive today. In October, despite the ongoing COVID pandemic, a team of researchers sailed from California to Antarctica to bring back the sea creatures with evidence of a long-lost transantarctic sea coded into their genes.

On the Wings of PetrelsScience | The Biological World Ecologist Donna Fraser carefully makes her way across a low rocky ridge towards a mass of gray feathers with a beak. It's the baby chick of a southern giant petrel. Feb

Counting on SealsScience | The Biological World Seal science in Antarctica continues, even as the COVID-19 pandemic spread across the world. Fewer researchers and support staff traveled to Antarctica in 2020 to reduce the risk of introducing the virus to the continent. One of the few science teams that did go is working on the long-term study of Weddell seals in McMurdo Sound. Jan

Weddell Seals Sing Songs Humans Can't HearScience | The Biological World The seals of McMurdo Sound are more vocal than previously thought. A new research paper published in the December edition of The Journal of the Acoustical Society of America shows that Weddell seals vocalize underwater at frequencies too high for humans to hear. Nov

An Aerial Assessment of Adelie PenguinsScience | The Biological World Flying robots are helping scientists track the population of Adelie Penguins. This past austral summer, researchers flew a small fleet of coordinated unmanned aerial vehicles, or "UAVs," over Cape Crozier, one of the largest Adelie penguin colonies in the world, photographing it in greater detail than ever before.

Detecting Anomalous Life SwarmsScience | The Biological World The seas around Antarctica are alive, but that life is not evenly distributed everywhere. Vast regions of barren ocean are punctuated by oases of concentrated nutrients that create hotspots of biological activity. Jun

Insects in the ExtremeScience | The Biological World Scientists are taking a close look at Antarctica's largest land animal. It's a small insect called the Antarctic midge, and they don't grow much bigger than a fingernail. May

Facing the Ultimate Acid TestScience | The Biological World Some of the Southern Ocean's smallest animals are facing big challenges. The once-exceedingly stable Southern Ocean around Antarctica is warming, and as it absorbs carbon dioxide from the atmosphere, it is also growing more acidic. Apr

Masses of MossesScience | The Biological World As the continent warms, Antarctica is getting greener. Plants are taking hold where glaciers once covered the landscape. Moss in particular is sprouting up in new spots where it had been previously inhospitable. While moss isn't a new arrival to the continent, its spread could mean big changes for the ecosystems of Antarctica. Apr

A Seal Grows In AntarcticaScience | The Biological World Weddell seals thrive in some of the coldest conditions on the planet, but scientists aren't quite sure why they don't freeze when they're first starting out.
