Air Pollution Can Be So Cool — ing
Fossil-fuel pollution has been offsetting global warming to the tune of about 30 percent per year. Cleaning up that pollution, a must, threatens to accelerate warming unless humanity changes its fuel-use strategy.

Squid beaks are hardly soft
Water softens squid beaks toward their base, so they don't cut into the squid's own soft tissue.

Live Another Day: African insect survives drought in glassy state
When dehydrated, the larvae of an African fly replace the water in their cells with a sugar, which solidifies and helps keep cellular structures intact.

Too speedy for gravity?
A new analysis suggests that five different spacecraft gained more speed as they flew past Earth than can be accounted for by Einstein's theory of gravitation.

Black Hole of Light: Laser pulses create model of event horizon
Physicists have created the optical analog of a black hole's surface of no return, a setup that could help test whether actual black holes glow.

Birds network too
Starlings in a flock adjust their trajectories to those of their closest neighbors, which helps the flock stay together when under attack.

Extreme Measures
Physicists use atom interferometry to measure gravity and other forces with unrivaled precision, and the technique could potentially guide airplanes and uncover buried caches of oil and diamonds.
