27 August 2008
Slow-moving nanoparticles hitting a surface bounce away, but surprisingly, fast-moving ones stick. New simulations explain that the sticking occurs because the fast particles absorb the collision energy by transforming their atomic structure.

11 August 2008
A large fraction of an antimatter beam can reflect off of a wall made of normal matter instead of annihilating. The surprising effect turns out to follow from standard, textbook physics.
