High-precision argon dating was used to analyze tektites and bentonites derived from a bolide impact associated with the mass extinction event at the boundary of the Cretaceous and Paleogene periods.
This paper uses total internal reflection microscopy (TIRF) to visualize single molecules of proteins that are important in decoding, copying, and rearranging DNA.
In this manuscript, the authors labeled cancer cells with magnetic beads and held them in place using a magnetic-pin array. This method may clarify how cancer cells invade tissues.
