Recently, cyanobacteria have gained attention in space exploration to support long-term crewed missions via Bioregenerative Life Support Systems. In this frame, cyanobacteria would provide biomass and profitable biomolecules through oxygenic […]
NASA astronauts Butch Wilmore and Suni Williams, who flew to the International Space Station on Boeing’s Starliner spacecraft, spent June 12 focusing on lab maintenance and researching advanced biotechnology.
![Distribution of the Galactic P-normal stars with [P/Fe]< 1 on the [Fe/H]−[P/Fe] plane and illustration of the predicted evolutionary path of the “ONe nova” scenario (wide gray line). Observational results for P-normal stars ([P/Fe]< 1) from (i) Roederer et al. (2014, 2016), (ii) Maas et al. (2022), and (iii) Caffau et al. (2016, 2019), M20, Maas et al. (2022), and Nandakumar et al. (2022) are plotted by filled circles, open circles, and crosses, respectively. The gray line just illustrates how [P/Fe] evolves with [Fe/H]: the exact details of the evolutionary paths (e.g., [Fe/H] at the maximum [P/Fe]) from the present chemical evolution model can be different from this line. Characteristic features of the models are explained with short phrases at appropriate places (e.g., “CCSN only” at [Fe/H]< −2.4). -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/05/Phosphorus-enrichment.png?resize=1200%2C720&ssl=1)
Recent observations have shown that [P/Fe] in the Galactic stars decreases with increasing [Fe/H] for [Fe/H] > -1 whereas it is almost subsolar for [Fe/H]< -2. These [P/Fe] trends with […]
Expedition 70 Flight Engineer and NASA astronaut Matthew Dominick works inside the BioFabrication Facility using the portable glovebag aboard the International Space Station’s Columbus laboratory module.
The beginning of life on Earth and its evolution over billions of years continue to intrigue researchers worldwide. The central dogma or the directional flow of genetic information from a […]
Editor’s note: although NASA did not sponsor research wherein tardigrade proteins were tested in human cells to see if they work – someone did. This emerged as the result of […]
Some soil bacteria can acquire sets of genes that enable them to pump the heavy metal nickel out of their systems, a study has found. This enables the bacteria to […]
Space biology research aims to understand fundamental effects of spaceflight on organisms, develop foundational knowledge to support deep space exploration, and ultimately bioengineer spacecraft and habitats to stabilize the ecosystem […]
At first glance, the search for life beyond Earth might not seem related to human illness. But to biochemist Steven Benner, the connection is clear.
Ten years ago, it was predicted that the multi-omics revolution would also revolutionize space pharmacogenomics. Current barriers related to the findable, accessible, interoperable, and reproducible use of space-flown pharmaceutical data […]
