Issues

Hole-doped carbon-60 crystals turn out to be better superconductors than their electron-doped cousins. And, if the critical temperature increases as the lattice expands, T _c might even exceed 100 K.

Super-Kamiokande data strongly disfavor hypothetical sterile neutrinos as partners in the oscillation of neutrinos from cosmic-ray showers.

A task force finds no showstoppers in developing the National Ignition Facility’s laser system.

A cross section of physicists has revived efforts to build a Gran Sassostyle underground facility in the US.

Synchrotron radiation with photon energies at or below 1 keV is giving new insights into such areas as wet cell biology, condensed matter physics and extreme ultraviolet optics technology.

We can’t just leave the design of frontier accelerators to the specialists. Inventing clever new ideas requires the same talents that it takes to do experimental physics.

Structurally, this metal oxide resembles the high-T_c cuprates, but its superconductivity is more like the superfluidity of helium-3.
