Closed-loop In Situ Isolation Of Deep-sea Extremophiles Through Sensor-driven Microenvironment Preservation
[Nature Sensors] Deep sea microorganisms remain largely inaccessible because existing sampling and cultivation methods fail to preserve native high-pressure microenvironments from seafloor to laboratory.

How A Deep-sea Protein Adapts To An Extreme Environment
[Kyushu University] Life in the deep sea is under immense pressure—literally. Such extreme conditions can disrupt the delicate structures of proteins essential to life. Yet somehow, the proteins in deep-sea […]

Global Carbon Fixation In Earth’s Subsurface Biosphere
[biorxiv.org] The subsurface of our planet hosts 15% of Earth’s biomass and plays a key role in mediating the exchange of volatiles and elements between deep, long-residence-time geological reservoirs and […]

Potential Survivable Niches For Microbial Life On The Lunar South Pole
[astro-ph.EP]. Most lunar surface conditions are incredibly harsh for microbial survival. High ultraviolet radiation, temperatures, and energetic particle radiation limit survival over most unprotected lunar surfaces, particularly in equatorial regions […]

Antarctica Is Home To Microbes Found Nowhere Else On Earth
[CU Boulder] Scientists have often wondered about species that are unique to Antarctica. But the focus has mainly been on animals, like cute feathery penguins. But CIRES researchers wanted to […]

Rethinking The Origin Of Life At Seafloor Hydrothermal Vents
[PNAS] Alkaline vents have dominated a class of hypotheses for the origins of life since their discovery a quarter of century ago, but advances in understanding the nature of these […]

Cultivation Of Halophilic Archaea In Shallow Subsurface Martian Conditions Has Implications For Extant Life On Mars
[biorxiv.org] The present-day martian surface is generally considered inhospitable to life because of low atmospheric pressure, intense surface radiation, global desiccation, and oxidizing chemistry which has been increasing since the […]
