Antiviral Activity of Metal-Containing Polymers—Organotin and Cisplatin-Like Polymers (open access)

Antiviral Activity of Metal-Containing Polymers—Organotin and Cisplatin-Like Polymers

This article examines the use of metal-containing polymers as a novel class of antivirals. Polymers containing platinum and to a lesser extent tin, have repeatedly demonstrated antitumor activity in vitro and in vivo against a variety of cell and tumor types. The mechanisms responsible for the antitumor activity include inducing a delay in cell proliferation and sister chromatid exchanges blocking tumor growth.

Delayed Antarctic melt season reduces albedo feedback (open access)

Delayed Antarctic melt season reduces albedo feedback

Article discusses how Antarctica's response to climate change varies greatly both spatially and temporally. The authors used a 43-year record of Antarctic snow melt seasons from space-borne microwave radiometers with a machine-learning algorithm to show that both the onset and the end of the melt season are being delayed.
