Scientists have pulled back the curtain on one of the most extreme solar regions seen in decades, tracking it almost nonstop for three months as it unleashed powerful space weather. By combining views from two spacecraft--one near Earth and one ...

At extreme pressures and temperatures, water becomes superionic -- a solid that behaves partly like a liquid and conducts electricity. This unusual form is believed to shape the magnetic fields of Uranus and Neptune and may be the most common type of ...

Honey bees can normally keep their hives perfectly climate-controlled, but extreme heat can overwhelm their defenses. During a scorching Arizona summer, researchers found that high temperatures caused damaging temperature fluctuations inside hives, . ...

Scientists tracking Earth's water from space discovered that El Niño and La Niña are synchronizing floods and droughts across continents. When these climate cycles intensify, far-apart regions can become unusually wet or dangerously dry at the same ...
