Enhancing the sensing capabilities of diamonds with quantum properties

When a nitrogen atom is next to the space vacated by a carbon atom, it forms what is called a nitrogen-vacancy center. Now, researchers have shown how they can create more NV centers, which makes sensing magnetic fields easier, using a relatively simple method that can be done in many labs.

'Labyrinth' chip could help monitor aggressive cancer stem cells

Inspired by the Labyrinth of Greek mythology, a new chip etched with fluid channels sends blood samples through a hydrodynamic maze to separate out rare circulating cancer cells into a relatively clean stream for analysis. It is already in use in a breast cancer clinical trial.

Unique property of critical methane-producing enzyme discovered

An unexpected discovery has given a group of scientists a greater understanding of an important methane-producing enzyme called methyl-coenzyme M reductase, or MCR. Their findings overturn what was previously believed to be true in the field: that a set of unique modifications present in MCR were essential to how the enzyme functions.

Rapid imaging of granular matter

Granular systems such as gravel or powders can be found everywhere, but studying them is not easy. Researchers have now developed a method by which pictures of the inside of granular systems can be taken 10,000 times faster than before.
