One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton's law of gravity to their visible matter, despite those ...
Astronomers, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China's Guizhou Province, have found an abundance of gas-rich galaxies in the distant universe.
What if your earbuds could do everything your smartphone can do already, except better? What sounds a bit like science fiction may actually not be so far off. A new class of synthetic materials could herald the next revolution ...
Silent discos started back in the 1970s as a convenient way to get around noise restrictions. In those days that meant everyone bringing their own music loaded onto a Walkman. Later, DJs would set up their own radio channels ...
The sun is increasing its intensity on schedule, continuing its approach to solar maximum. In just over a 24-hour period on May 5 and May 6, 2024, the sun released three X-class solar flares measuring at X1.3, X1.2, and X4.5. ...
Pulsar timing enables the most stringent tests of fundamental physics. By monitoring the pulse times of arrival (ToAs) of an ensemble of stable millisecond pulsars (MSPs), known as a pulsar timing array (PTA), it is possible ...
A perspective published in PNAS Nexus explores lessons learned from recent deadly wildfires and proposes a strategy for managing wildfire risk.
In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking ...
Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) have identified a way for plants to gain resistance to cesium, a radioactive toxin that can be found in contaminated soil. After manipulating a specific ...
Among the jagged peaks of the North Cascades, lush alpine meadows rich with berries and wildflowers blanket valleys carved by glaciers, some threaded with trickling creeks.
