Atmospheric blocking as a traffic jam in the jet stream
Atmospheric blocking due to anomalous, persistent meandering of the jet stream often causes weather extremes in the mid-latitudes. Despite the ubiquity of blocking, the onset mechanism is not well understood.

Single-crystal x-ray diffraction structures of covalent organic frameworks
The crystallization problem is an outstanding challenge in the chemistry of porous covalent organic frameworks (COFs).
