Phys.org / Roman telescope will spot distant black holes that shred stars

How do black holes at the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances that existed much earlier in the universe's history. ...

Phys.org / 'Amazing moths': Study pinpoints insect habitat that draws grizzlies to glacier peaks

When grizzly bears clamber onto the talus slopes high in Glacier National Park, they're searching for an abundant, fatty meal: army cutworm moths. The inch-long (2.5-centimeter-long) moths hatch on the Great Plains and fly ...
