Astrophotographer Adam (AJ) Smadi caught this image a few hours ago from Washington state. A thin crescent Moon, sunlight illuminating the rugged lunar surface. And 2,400 times farther away—and on the other side of the Sun—mighty Jupiter, and its moons Io (left) and Ganymede (right).
A crescent Moon seen during the day, arcing from upper left to lower right of the frame. At lower centre is the full disk of Jupiter; the small dots to its upper left and lower right and Io and Ganymede, respectively.

Once again, child dies in gene-editing trial in China, rekindling debate on transparency and safety
With a second delayed report of a child's death in China, criticism is rising of a looser form of clinical trial. One expert: what "bothers me is the lack of transparency."
