Spin Control A new system can smoothly guide a pendulum from stable to unstable motion and find the border between the two states. Similar set-ups might someday improve testing of auto or airplane parts. Image: J. Sieber et al./Univ. of Bristol A Nanoscale Tractor Beam A new theory on the interactions of nanoparticles with laser light predicts some surprising effects when more than one particle is involved, such as a particle being drawn toward the source of the beam, against the flow of photons.
