With 302 neurons, 200 of them in their heads, hermaphrodite female roundworms reveal surprising sex-specific differences in the nervous system and how these differences influence behavior, reproduction, and aging. Researchers at Northeastern University compared brain activity in male and hermaphroditic Caenorhabditis elegans, a microscopic worm widely used in biological research to understand how sex wires males and female nervous systems differently.

Archaeologists have discovered a faience workshop at a major temple complex in the ancient Nubian capital of Napata, showing how the rulers of ancient Kush used specialized craft production to reinforce royal power.

More than 99% of the US population lives under light-polluted skies, according to a 2016 study published in Science Advances. With streetlights, brightly lit parking lots, arenas, and passing headlights brightening the night, it can be easy to forget how dark the sky actually is and how many stars appear when you get away from populated areas. Seeing that many stars for the first time can make you pause and remember where you truly are. You are on a rock spinning through space, surrounded by a universe filled with stars, planets, and galaxies larger than anything you can imagine. A remote mountain excursion can combine a dark sky encounter with a day of hiking and sightseeing. After sunset, bright stars emerge above the slopes and ridgelines. These American mountains lie within officially designated dark sky locations that protect natural darkness and the views of the universe it reveals. In northeastern New Mexico, Capulin Volcano sits among volcanic cones, mesas, and buttes in one of the darker areas of the lower 48 states. These landforms help shield the night sky from distant lights, while the rugged terrain has discouraged development in the area.
