Astrophysicists working with the JWST have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang. How does that fit in with our understanding of the universe?
Many organizations, from community sporting groups to the United Nations, have set themselves a target of gender parity: ensuring half of staff or members are women. Gender parity is desirable because training and retaining ...
The idea that protons and neutrons were composed of even smaller particles, with non-integral electric charges, was proposed in 1963/64 by Andre Petermann, George Zweig and Murray Gell-Mann, who dubbed them "quarks." It was ...
For the past few decades, physicists and materials scientists around the world have been busy developing computer codes that simulate the key properties of materials, and they can now choose from a whole family of such tools, ...
Researchers are working tirelessly to find new materials for future technologies that are essential for the energy transition—as electrocatalysts, for example. Due to their versatile properties, materials consisting of ...
Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen—casting new light on how heavy elements are made.
After a journey of seven years and nearly 4 billion miles, NASA's OSIRIS-REx spacecraft landed gently in the Utah desert on the morning of Sept. 24, 2023, with a precious payload. The spacecraft brought back a sample from ...
Researchers have discovered a way to make ceramics tougher and more resistant to cracking. By building these materials using a blend of metal atoms possessing more electrons in their outer shell, a team led by engineers at ...
The universe is flooded with billions of chemicals, each a tiny pinprick of potential. And we've only identified 1% of them. Scientists believe undiscovered chemical compounds could help remove greenhouse gases, or trigger ...
Some asteroids have measured densities higher than those of any elements known to exist on Earth. This suggests that they are at least partly composed of unknown types of "ultradense" matter that cannot be studied by conventional ...
