Forever chemicals lingering in Antarctic marine mammals

Science | The Biological World

New research finds Antarctic seals and killer whales still have persistent organic pollutants stored in their blubber, despite many countries having phased out production of these toxic chemicals, some as long as 50 years ago.

The stone thieves

Science | The Biological World

Adelie penguins often steal stones from each other's nests, but new research shows the wily birds target some nests more than others.

Scoping out the seal mating scene

Science | The Biological World

Biologists have been observing how male Weddell seals secure prime locations when courting females to learn more about the southernmost mammal's mysterious breeding behavior.

Meet the Penguin Misfits

Science | 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.

Coldest, Driest, Saltiest Antarctic Soils Might Be Inhospitable To Life

Science | 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 Mollusks

Science | 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.

Charting a Genetic Sea Change

Science | 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 Petrels

Science | 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.

Counting on Seals

Science | 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.

Weddell Seals Sing Songs Humans Can't Hear

Science | 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.

An Aerial Assessment of Adelie Penguins

Science | 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 Swarms

Science | 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.
