The DNA foundation model Evo 2, first released in February 2025 as a preprint, is now published in the journal Nature. Trained on the DNA of over 100,000 species across […]
Join ESA and NASA on 11 March 2026 (16:00-18:00 CET) for a seminar on how ESA omics data are shared, curated and accessed through NASA’s Open Science Data Repository (OSDR). […]
During spaceflight, astronauts are exposed to extreme conditions such as microgravity, cosmic radiation, and confinement, which can cause a wide range of health problems.
The SpaceX Inspiration4 mission provided a unique opportunity to study the impact of spaceflight on the human body.
The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that’s added to […]
The NASA Open Science Data Repository (OSDR) and Physical Sciences Informatics (PSI) provide open access to biological and physical science datasets from spaceflight and ground studies, enabling data reuse for […]
Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to […]
Editor’s note: If we aspire to mount expeditions to new worlds and then embrace the task of characterizing and quantifying whatever life forms we find, the ability to map and […]
![Adapted from fig. 1.8 of [2]. Modern protein synthesis; the anticodon at one end of a tRNA molecule binds to its complementary codon in mRNA derived directly from the genome. Sequence-to-sequence translation is not highly parallel, in this model, and the process can be characterized in terms of the Shannon uncertainty in the transmission of information between codon machinery and amino acid machinery. -- biorxiv.org](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/06/Biochemical-%E2%80%98Cambrian-explosion.png?resize=1200%2C720&ssl=1)
Tlusty’s topological analysis of the genetic code suggests ecosystem changes in available metabolic free energy that predated the aerobic transition enabled a punctuated sequence of increasingly complex genetic codes and […]
Translation of symbols in one chemical language into another defined genetics. Yet, the co-linearity of codons and amino acids is so commonplace an idea that few even ask how it […]
