Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a "lying ...
Deep inside super-Earths—rocky planets with masses between 1 and 10 times that of Earth—high pressure can cause familiar minerals to take forms rarely seen on Earth. Understanding more about the temperature and pressure conditions ...
If scientists could find a material that acts as a superconductor—that is, one that transmits energy with zero resistance—at normal pressures and relatively high temperatures, it would open up a vast number of possibilities. ...
From routine surgeries to cancer treatment, modern medicine depends on drugs that can fight infections caused by microbes such as bacteria, viruses, fungi and parasites. But some microbes are becoming resistant to the drugs ...
Earth's oceans repeatedly lost oxygen and produced metal deposits during the planet's deepest ice ages. An international team of researchers analyzed manganese and other chemical signatures preserved in more than 27,000 ancient ...
For decades, scientists have asserted that the leakage of warm, salty Indian Ocean water south of South Africa into the Atlantic is a major contributor to the Atlantic Meridional Overturning Circulation (AMOC), a component ...
Butterflies are charismatic, colorful and cherished around the world. One of the most diverse groups of insects, with more than 19,000 described species, they inspire international organizations such as the North American ...
A drifting SpaceX rocket is on a collision course with the moon after launching a pair of lunar landers more than a year ago.
Every night, astronomers must carefully assess changing weather, the intensity of moonlight and shifting atmospheric conditions before deciding where to point a telescope. It's a constant balancing act designed to squeeze ...
In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Because of their small sizes and locations, these satellites have been difficult ...
