A year of full-sky observation by the newly rechristened Wilkinson Microwave Anisotropy Probe greatly strengthens the case for inflationary Big Bang cosmology.

At modest magnetic fields and microwave excitations, the resistance of a 2D semiconductor can oscillate all the way to zero.

The attophysics frontier is about to expand, thanks to the newly won ability to control the phase of amplified laser pulses.

Martin Fisher puts his mind to using technology to facilitate microentre-preneurs in East Africa.

Russia and other former Soviet republics inherited a massive nuclear weapons program they could no longer afford. Thousands of former weapons scientists have been subsidized by US grants, but finding them permanent, civilian jobs has proven to be extremely difficult.

No longer threatened by a rival superpower, the US now faces the growing danger of clandestine terrorist groups. Effectively countering terrorists requires that physicists actively contribute to the nation’s defense.

It’s not your grandfather’s quantum mechanics. Today, researchers treat entanglement as a physical resource: Quantum information can now be measured, mixed, distilled, concentrated, and diluted.

Using very distant supernovae as standard candles, one can trace the history of cosmic expansion and try to find out what’s currently speeding it up.
