Regular exercise does more than strengthen the heart. New research reveals that it actually reshapes the nerves controlling how the heart functions, and the changes are surprisingly different on the left and right sides of the body.

A simple liquid painted onto teeth in seconds can stop cavities without drilling, injections, or anesthesia, according to a major clinical trial involving young children. The inexpensive treatment could spare thousands of children painful dental procedures and surgery while paving the way for broader FDA-approved use.

A solar eclipse recorded more than 2,700 years ago is revealing surprising secrets about Earth's rotation and the Sun's ancient behavior. By correcting an eight-kilometer error in the location of an ancient Chinese capital, scientists were able to reconstruct a total solar eclipse that occurred in 709 BCE and obtain more accurate measurements of how fast Earth was spinning at the time.

Researchers have developed a groundbreaking 3D invisibility cloak that can hide complex objects from infrared cameras while protecting them from extreme heat and cold. Instead of blocking heat, the device guides it around an object, making the object appear invisible to thermal imaging from virtually any direction. Successfully built and tested, the cloak could transform electronics cooling, thermal protection, and stealth technology.

Scientists have filmed tiny magnetic vortices called skyrmions melting out of an organized lattice for the first time, revealing new ways to manipulate these unusual structures. The breakthrough could help make brain-like computers a reality, potentially enabling dramatically smaller and more energy-efficient technology.
