Semiconductor quantum dots take first steps toward spin-based quantum computation
Using nanosecond voltage pulses, researchers can entangle and rotate spin qubits in a double quantum dot—on demand.
Enormous magnetic reconnection event washes over three spacecraft millions of kilometers apart
How large can reconnection events in plasmas get? Theory provides no easy answer. But the solar wind beyond Earth’s cramped magnetosphere is a good place to look.

Outlook for French science still uncertain, even as CNRS crisis subsides
Two years after their massive street protests, French researchers are worried that science remains underfunded and that the government is grabbing increasing control over the directions of research.
Bush budget boosts NSF, DOE, and NIST science for FY 2007
Although nearly all non-defense spending takes a big hit under Bush’s proposed FY 2007 budget, basic research and science education get strong support.

Fifty years of seeing atoms
Beyond imaging atoms, clusters, and defects on a surface, today’s microscopes can distinguish elements, monitor their diffusion and redistribution near the surface, and even create designer nanostructures and reactions.
Two hundred years of capillarity research
Two centuries after seminal work by Pierre-Simon Laplace and Thomas Young, capillarity’s modern applications arise in fields ranging from biology and oceanography to propulsion, materials science, and novel devices.
Macromolecular phasing
Several techniques, well established and newly developed, allow crystallographers to reconstruct large molecular structures after recovering the phases that are lost in x-ray diffraction patterns.
