Hard-to-burn ‘smart’ wallpaper even triggers alarms
Scientists have made wallpaper that won’t easily burn. And embedded nanowires can be linked to a sensor to sound an alarm when the paper gets too hot.

PhysicsClosing in on fusion energy
Scientists blasted a tiny capsule of hydrogen with laser beams, setting off a reaction that released more energy than in earlier experiments. Still, scientists remain a long way from creating a reaction that releases more energy than it needs to get started.
