Astronomers used RR Lyrae stars to trace the early Milky Way, revealing a rapid formation of its halo and disk, with chemical patterns similar to Andromeda.

UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally ...

A logarithmic spiral with a diameter of 500 μm, approximately half the diameter of a sewing needle. Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led ...

Clues about how galaxies like our Milky Way form and evolve and why their stars show surprising chemical patterns have been revealed by a new study. When scientists study stars near the Sun, they find ...

A computer simulation shows metallic alloy where atoms (colored spheres) are arranged in subtle chemical patterns beneath a network of dislocations (green lines). These tangled defects move during ...

Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. This new study shows that the mathematical basis of these patterns also governs how sperm tail ...
