Experiment finds Earth “dragging” spacetime, as Einstein predicted. Einstein knew his physics. Bending light, gravity lenses, shifting spacetime, spinning neutron stars: he called them all.

Could carbon storage help control warming? The oil industry already injects CO2 into deep rocks. Is it possible to capture CO2 from coal plants, and pump it deep underground?

Infrared survey of Milky Way shows massive star formation. How could a supernova cause stars to start?

The Spallation Neutron Source, a mammoth science project involving the collaboration of six national laboratories, is scheduled to be completed 2006.

Existing nukes may not exhaust the possible nukes. What other weapons could appear on the nuclear shelf?

New photovoltaic (PV) cells combine polymer and inorganic semiconductors — could be cheaper to manufacture.

Worldwide thirst for oil, Hurricane Katrina, political instability, conservation failures add up to record demand and record prices for fuel. Can inherently “safe designs” reduce the risk of meltdown? Should we support a revival of fission power?
