scientists were able to use Mark as a baseline for how the long spaceflight had changed Scott.) In 2017 Russia temporarily cut the number of its ISS crew from three to two, and American astronaut Peggy Whitson extended her mission to 289 days, which at that time was the longest single spa...
TheJames Webb Space Telescope (JWST)has helped astronomers see what could be three of the universe's earliest galaxies. The galaxies are seen as they were when the13.8 billion-year-old cosmoswas between 400 million and 600 million years old. The threegalaxies are in the process of formingas ...

The structure of nanocrystal superlattices has been extensively studied and well documented, however, their assembly process is poorly understood. In this work, we demonstrate an in situ space- and time-resolved small angle X-ray scattering measurement t
By virtue of their different group velocities, the wave packets gradually separate in time by a group delay that depends on the difference between their group velocities and the propagation distance. Fig. 1: Concept of a free-space optical delay line using ST wave packets. a Overall layout. ...
To quantitatively evaluate the biosynthetic chemical space of marine prokaryotes, we first determined the relationship between chemical similarity and BGC similarity for a set of 1087 bacterial BGCs with known metabolites from the MIBiG database. As shown in Fig. 2A, the median Tanimoto similarity of...
