Lineage-specific positive selection on ACE2 contributes to the genetic susceptibility of COVID-19OA

The Angiotensin-Converting Enzyme-2(ACE2) gene,located on Xp22.2, attracts a great deal of attention because the protein it encodes is believed to be the functional cellular receptor for the new coronavirus(SARS-CoV-2).However,recent studies are controversial,especially concerning the intrinsic link between ACE2 diversity and COVID-19 susceptibility.Here,we conduct a population genetic study on ACE2 in6354 individuals representing 210 present-day populations and 5 329 individuals of ancient or a...     

Wax from Pyrolysis of Waste Plastics as a Potential Source of Phase Change Material for Thermal Energy Storage

Over the past half-century, plastic consumption has grown rapidly due to its versatility, low cost, and unrivaled functional properties. Among the diff erent implemented strategies for recycling waste plastics, pyrolysis is deemed the most economical option. Currently, the wax obtained from the pyrolysis of waste plastics is mainly used as a feedstock to manufacture chemicals and fuels or added to asphalt for pavement construction, with no other applications of wax being reported. Herein, the th...
