Biological aggregation is a critical, yet often overlooked factor in the medical application of nanoparticles. Here scientists systematically characterize the effects of aggregation on both radiofrequency heating and magnetic resonance image (MRI) contrast of magnetic iron oxide nanoparticles, including detailed analysis of the aggregate morphologies based on quasi-fractal descriptions.

In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now scientists have figured out an elegant way to stop a molecule from tumbling so that its potential for new applications, such as quantum computing, can be harnessed: shine a single laser on a trapped molecule and it instantly cools to the temperature of outer space, stopping the rotation of the molecule.

Scientists have been studying the effects of embedding magnetic spins onto the surface of a superconductor. They report that the spins can interact differently than previously thought. This hybrid platform could be useful for quantum simulations of complex spin systems, having the special feature that the interactions may be controllable, something quite unusual for most condensed matter systems.
