Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
Predicting metabolic potential in bacteria from limited genome data
How bacteria eat food, and what kinds of products they can make from that food, is dictated by the metabolic network of enzyme patterns encoded in their genomes. Using computational methods to learn these patterns across a large number of known bacte.....»»
