TL;DR: The cytotoxicity and oxidative stress caused by 20-nm cerium oxide (CeO2) nanoparticles in cultured human lung cancer cells was investigated and it was concluded that free radicals generated by exposure to 3.5 to 23.3 μg/ml CeO2 nanoparticles produce significant oxidative stress in the cells.

TL;DR: Exposure to both sizes of ZnO particles leads to dose- and time-dependent cytotoxicity reflected in oxidative stress, lipid peroxidation, cell membrane damage, and oxidative DNA damage, as well as a much steeper dose–response pattern unseen in other metal oxides.

TL;DR: In this article, a cross-correlation analysis on the data from Advanced LIGO's second observing run (O2) is presented, which combines with the results of the first observing run, and upper limits on the normalized energy density in gravitational waves at the 95% credible level of ΩGW < 6.0 × 10−8 at 25 Hz for a background of compact binary coalescences.

TL;DR: In this article, the sky localization of the first observed compact binary merger is presented, where the authors describe the low-latency analysis of the LIGO data and present a sky localization map.
