Electrons in atomically thin carbon sheets behave like massless particles
Traditionally found in particle-physics and cosmology contexts, the relativistic Dirac equation also describes how electrons move in a unique two-dimensional condensed matter system, graphene.
Densely packed positronium atoms interact chemically
For the first time, experimenters have seen atoms made from an electron and a positron exchange spins and perhaps form diatomic molecules.
Optical trap resolves the stepwise transfer of genetic information from DNA to RNA
The assembly of RNA can now be tracked with a precision finer than the distance between its bases.
Issues and Events
Basic science funding flat, as war, deficit, and hurricane recovery squeeze federal budget
Most R&D agencies barely held their own in yet another year of modest science funding. A proposed across-the-board 2% cut could push many science programs into the red.
Mauna Kea telescopes step up collaborations
Tight budgets and pricey instruments are spurring a trend among observatories to swap time. To work, though, cultural, technical, financial, and administrative wrinkles need to be ironed out.
Evolution wins in Pennsylvania, loses in Kansas
A slate of “real-world” candidates swept the intelligent design majority off the Dover, Pennsylvania, school board, while in Kansas antievolutionists not only weakened science standards, but redefined science itself.

Oil on troubled waters: Benjamin Franklin and the honor of Dutch Seamen
Men who worked at sea knew of the calming effects of oil on water long before Franklin began his investigations. Was their practical knowledge any different from the later scientific knowledge of the learned?
Benjamin Franklin and lightning rods
Franklin’s work on electricity and lightning earned him worldwide fame and respect—ideal assets for brokering aid from France during the American Revolution.
Vehicle design and the physics of traffic safety
Light trucks cannot safely coexist with passenger cars under existing conditions. The problem becomes particularly urgent as more and more light trucks are used simply as car substitutes.
