A team led by Caltech's André Hoelz has solved the architecture of the nuclear pore complex's complicated inner ring, a subcomplex that is central to the cellular machine's function. In the process, they disproved many previously held ideas about how the inner ring works.

Caltech's Thomas F. Rosenbaum and colleagues at the University of Chicago and the Argonne National Laboratory recently used a synchrotron X-ray source to investigate the existence of instabilities in the arrangement of the electrons in metals as a function of both temperature and pressure, and to pinpoint, for the first time, how those instabilities arise.

The finding of cold gas flowing into a galaxy-in-the-making provides strong support for the cold-flow model of galaxy formation in the early universe.

Mosquitoes use olfactory, visual, and thermal clues to hunt down a human host for their next meal—and avoiding their annoying bites might be next to impossible, a recent Caltech study says.
