Discovery of space soot casts doubt on dark energy theory

Guardian Unlimited: In space, no one can hear you scream — which is no bad thing, because scientists have discovered that it is a lot filthier than they thought.
Researchers revealed yesterday that limitless stretches of space are strewn with interstellar soot, making it harder to see very distant objects such as exploding stars or supernovae.

Physicists discover a different way to board a plane

Nature: Fermilab’s Jason Steffen became so frustrated over the delays in boarding an aircraft that he decide to do something about it. He has applied a computational technique commonly used to map the movement of atoms and molecules to simulate how passengers move around a gridded space on an aircraft. According to his research the most common way airlines use to board passengers on an aircraft is mathematically, an extremely inefficient technique. Instead he suggests applying a strictly ordered optimal sequence that cuts boarding times by a factor of 7.
