Dale Andersen’s Astrobiology Antarctic Status Report: 18 February 2026: Eclipse Watching And Base Camp Packing
Dale: A partial eclipse over Lake Untersee yesterday—an ordinary piece of celestial clockwork that felt anything but ordinary from the icy shores of Lake Untersee in the mountains of Antarctica. […]
Dale Andersen’s Astrobiology Antarctic Status Report: 15 February 2026: Diving Under The Ice At Lake Untersee
Keith, Sorry for the quiet—our days have been packed, and out here every usable hour feels borrowed. Since my last report the weather has changed its mind a few times. […]
Life In The Brine Of Lunenburg, Germany: Unveiling Microorganisms Associated With Zechstein Salt Deposits
Introduction: The presence of hypersaline brines on other planets and moons in the inner and outer Solar System has been well established.
Ocean World Genomic Assays: Searching For Terrestrial Cephalopod DNA
New DNA probes allow for efficient surveying of the hidden lives of squids and octopuses in the deep sea. This development by Kobe University provides an effective tool for marine […]
Ocean Planet Exploration Droids: Autonomous eDNA Collection Using An Uncrewed Surface Vessel
The collection of environmental DNA (eDNA) samples is often laborious, costly, and logistically difficult to accomplish at high frequency in remote locations and over large geographic areas.
Ocean World Genomics: Molecular Monitoring For Marine Change And Threats Using eDNA
New DNA* technology promises to improve efforts to monitor marine life in the Southern Ocean, and detect the presence of non-native marine species close to Antarctica.
Electricity From Electric Eels May Transfer Genetic Material To Nearby Animals
Editor’s note: as is stated in this press release, electroporation is a well-known way to deliver genetic information into a cell – in the laboratory. The fact that this happens […]
Tricorder / Away Team Tech: A Drone That Collects Environmental DNA From Trees
Ecologists are increasingly using traces of genetic material left behind by living organisms left behind in the environment, called environmental DNA (eDNA), to catalogue and monitor biodiversity. Based on these […]
