In this paper, we report a fully automated, end-to-end (sample-in/data-out) capillary electrophoresis system.
The surface and subsurface of worlds beyond Mars remain largely unexplored. Yet these worlds hold keys to fundamental questions in planetary science – from potentially habitable subsurface oceans on icy […]
The search for signatures of life beyond Earth has been a major goal of space research and astrobiology for decades. The combination of expanded knowledge on Solar System bodies from […]
![Overview. (a) Composition of a bacterial cell by weight, with a breakdown of the chemical constituents [21]. About 40% of these compounds are not properly covered in existing datasets. (b) Multi-step workflow used to construct QCell, beginning with the selection of building blocks, followed by conformational sampling and fragment selection, pre-optimization with DFTB+MBD, and finally hybrid PBE0+MBD(-NL) calculations. (c) Coverage of molecular species at the PBE0+MBD(-NL) level of theory, including entries from existing databases and newly generated QCell data for nucleic acid fragments, lipids, sugars, solvated ions, and dimers. -- AI for Science](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/04/Mapping-The-Molecules-Of-Life.png?resize=1200%2C719&ssl=1)
Machine learning force fields (MLFFs) are rapidly transforming molecular simulations by combining the accuracy of quantum mechanics with the speed of classical approaches. However, training reliable MLFFs for biological systems […]
After years of lab work, the results are in: A rock that NASA’s Curiosity Mars rover drilled and analyzed in 2020 includes the most diverse collection of organic molecules ever […]
Saturn’s moon Titan is a prime destination for investigating prebiotic chemistry beyond Earth, particularly at impact crater sites where transient liquid water may have enabled aqueous reactions between organic molecules.
Editor’s note: with recent speculation about the potential habitability of other worlds and understanding the processes whereby other biospheres arise and evolve, thought needs to be given to developing sensor […]
Full report Exploration as a scientific endeavor exemplifies great American innovation. The first human steps on Mars will be a watershed moment for humanity and for science. The endeavor to […]
Debris-covered glaciers (DCGs) at the mid latitudes of Mars preserve ice accumulated in multiple episodes of high obliquity during the Amazonian age. The englacial debris layers formed during interglacials are […]
The Perseverance rover recently began exploring the Jezero crater rim after traversing the crater floor, fan deposits, and margin unit. In the rim deposits, several plagioclase-rich light-toned float rocks (LTF) […]
