The structure and history of near-Earth asteroids are important to
study because they collide with Earth, sometimes with significant consequences for
climate and the survival of many species, including our own. If NASA is ever to deflect an asteroid on a collision course, it is crucial to know as much as possible about its size, composition, structure and boulder distribution. The boulder
distribution in turn helps to map the asteroid's gravitational field.
1992 UY4 is a near-Earth asteroid discovered in 1992. In August 2005, UY4 made a
``close" (for space) pass of Earth, about 15x farther than the Moon. It …

Photoredox catalysis has direct applications in sustainable chemistry and thus an immense impact on our environment. With the ability to harness energy directly from the sun to catalyze useful chemical reactions, photocatalysts can help to eliminate the need for harsh reaction conditions and reduce generation of hazardous chemical waste. Photocatalysts based on Earth-abundant metals such as copper have recently emerged as sustainable alternatives to rare-earth metals including iridium and ruthenium, which are no longer required for many photocatalyzed chemical transformations.
