An international team of astrophysicists has discovered a galaxy 65 million light years away with so little dark matter that it may contain none at all.
Cavities propel charged particles by transferring energy from electromagnetic waves to the particles, speeding them up. Superconducting cavities are made of material that can conduct electric currents without resistance at a very low temperature.
There's a new scientific path in Princeton, New Jersey. Out of the loam of a vacant lot, a cluster of quasicrystals winks at some pink plasma. Tectonic plates shift, and neurons connect in a hippocampus curve of bamboo.
The highest-energy particle accelerator in the world, Fermilab's Tevatron, boasts four miles of particle-accelerating circumference. But during thunderstorms it can become a bull's-eye for stray lightning bolts that demonstrate the intimidating power of nature.
In the early 1950s, Nobel-Laureates-to-be Norman Ramsey and Ed Purcell created cards of physical constants they found themselves using most frequently.
Stanford Linear Accelerator Center librarian Lesley Wolf needed a creative idea for the next library display. Ten-year-old Connor Reed had lots of free time this summer and an extensive set of K'nex, the flexible equivalent of Lego.
