In this opinion paper, we argue that global health crises are also information crises. Using as an example the coronavirus disease 2019 (COVID-19) epidemic, we (a) examine challenges associated with what we term "global information crises"; (b) recommend changes needed for the field of information science to play a leading role in such crises; and (c) propose actionable items for short-and long-term research, education, and practice in information science.

The Lewis acid–surfactant–SiO2-combined (LASSC) nanocatalyst synthesizes BIMs, and has the advantages of being non-toxic, multi-cycle, highly stable and efficient.

A new and general photocatalytic Kharasch-type addition/1,5-(SN′′)-substitution cascade of 1,7-diynes with alkyl halides such as BrCCl3 and CBr4 was reported for the first time, producing 65 hitherto unreported β-gem-dihalovinyl ketones/aldehydes with moderate to excellent yields.
