The James Webb Space Telescope could help scientists learn about the cosmic dark ages and how they ended.
Helplessness isn't learned — it's an instinctual response that can be overcome.
In 1990, we only knew of the planets in our own Solar System. Today, the exoplanet count is more than 5000. Here's what we've learned.
About six minutes after the heart stops, the brain essentially dies.
Every year, scientists like George Church get better at editing the genomes of human beings. But will genome editing help or hurt us?
Salk scientists studied complex decision-making capabilities in a worm with just 302 neurons and a mouth full of teeth. It's smarter than you would think.
We have a morbid curiosity about nautical disaster stories. The Irish "Wreck Viewer" offers a window into centuries of marine misfortune.
Empty, intergalactic space is just 2.725 K: not even three degrees above absolute zero. But the Boomerang Nebula is even colder.
Scientists at the San Diego Zoo are on a mission to resurrect the extinct northern white rhino.
When we started imaging the Universe with Hubble, every star had four "spikes" coming from it. Here's why Webb will have more.
