A precise X-ray thermometer for warm dense matter

Warm dense matter (WDM) measures thousands of degrees in temperature and is under the pressure of thousands of Earth's atmospheres. Found in many places throughout the universe, it is expected to have beneficial applications ...

Fusion breakthrough is a milestone for climate, clean energy

Scientists announced Tuesday that they have for the first time produced more energy in a fusion reaction than was used to ignite it—a major breakthrough in the decades-long quest to harness the process that powers the sun.

Hot stuff: Lab hits milestone on long road to fusion power

With 192 lasers and temperatures more than three times hotter than the center of the sun, scientists hit—at least for a fraction of a second—a key milestone on the long road toward nearly pollution-free fusion energy.
