Attosecond Bursts Trace the Electric Field of Optical Laser Pulses
The familiar textbook sketch of light’s oscillating electric field can now be drawn directly from measurements.
New All-Electrical Measurement Schemes Can Detect the Spin State of a Single Electron
Spin-to-charge conversion improves prospects for semiconductor-based quantum information processing.
Intense X-Shaped Pulses of Light Propagate Without Spreading in Water and Other Dispersive Media
The nonlinear interaction of light with matter can imbue optical pulses with surprising and potentially useful properties.

NASA Bows to Pressure to Save Hubble
In a turnaround, NASA may extend the life of the Hubble Space Telescope by servicing it robotically. But doubts remain over the feasibility of such a mission, and over how NASA would pay for it.
Panel Chooses Superconducting Option for the International Linear Collider
Articles
Were Fundamental Constants Different in the Past?
Atomic physics, nuclear physics, and cosmology enable physicists to probe changes in the fine-structure constant over time scales ranging from a few years to nearly the age of the universe.
R-Process Nucleosynthesis in Supernovae
The heaviest elements are made only in cataclysmic events. Finding out whether supernovae are cataclysmic enough requires extensive astronomical observation and sophisticated computer modeling.
Shallow-Water Acoustics
Extracting a signal from noise can be complicated, especially along a coastline filled with marine life, shipping lanes, undersea waves, shelves, and fronts that scatter sound.
