Researchers have studied the dynamics of active swarms using computer simulations and experiments on unicellular algae. The team not only found full analogy of the active motion in a field to magnetic hysteresis but also managed to quantify the controllability of the swarm and identify the signatures of collective behavior of the active agents.

Researchers have succeeded in developing a new microscope capable of observing the magnetic sensitivity of photochemical reactions believed to be responsible for the ability of some animals to navigate in the Earth's magnetic field, on a scale small enough to follow these reactions taking place inside sub-cellular structures.

Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect-free materials break? Until recently, the question was purely theoretical; making a defect-free material was impossible. Now that nanotechnological advances have made such materials a reality, however, researchers have shown how these defects first form on the road to failure.
