HKUST Unlock Genomic Secrets of Deep-sea Tubeworm

Researchers from The Hong Kong University of Science and Technology (HKUST) have decoded the chromosomal-level genome of a deep-sea gutless tubeworm and the genome of its co-living "partner" - a kind of bacteria that provide nutrients they generate from inorganic compounds to the worm for the first time, explaining how the pair adapts to the extreme habitat.

Assessment of Ammonia as a Biosignature Gas in Exoplanet Atmospheres

Assessment of Ammonia as a Biosignature Gas in Exoplanet Atmospheres

Ammonia (NH3) in a terrestrial planet atmosphere is generally a good biosignature gas, primarily because terrestrial planets have no significant known abiotic NH3 source.

The Reflectance Spectra of CV-CK Carbonaceous chondrites from the Near Infrared to the Visible

The Reflectance Spectra of CV-CK Carbonaceous chondrites from the Near Infrared to the Visible

Carbonaceous chondrite meteorites are so far the only available samples representing carbon-rich asteroids and in order to allow future comparison with samples returned by missions such as Hayabusa 2 and OSIRIS-Rex, is important to understand their physical properties.

Cellular Remains in A ~3.42-billion-year-old Subseafloor Hydrothermal Environment

Cellular Remains in A ~3.42-billion-year-old Subseafloor Hydrothermal Environment

While Earth may have been a habitable planet long before the Paleoarchean Era [3.6 to 3.2 billion years ago (Ga)], as rocks of this age retain a diversity of fossil evidence for life the complexity of life's cellular constituents, range of metabolic pathways, the niches it occupied locally, and global diversity of its habitats remain largely unknown.

Hubble Finds First Evidence of Water Vapor at Jupiter's Moon Ganymede

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas.
