Nicknamed the atmospheric garbage disposal, the hydroxyl molecule is one of the most potent oxidizers throughout the atmosphere. Among its habitual targets is ozone.
A surprising new class of middleweight black holes, perhaps 10 000 times more massive than the Sun, may have much to teach us about how galaxies form.
For thousands of years, code‐makers and code‐breakers have been competing for supremacy. Their arsenals may soon include a powerful new weapon: quantum mechanics.
The prospects for meeting the Kyoto Protocol for greenhouse‐gas reductions will be brighter if the US can develop technologies to lower its energy use.
Recent insights from this well‐studied model have led to many new applications—from river networks to oil recovery, and from electrodeposition to string theory.
