Canada will require passengers seeking to board international flights into the country to show their airline proof of a negative coronavirus test, in addition to entering an already existing, mandatory 14-day quarantine on arrival.

The new rule, which the government announced on Thursday, will take effect on Jan. 7 and will require proof of a negative PCR test taken in the previous 72 hours. PCR tests must be sent to a lab and can take several days to process, unlike the rapid antigen test, which gives a result in about 30 minutes.

Biological membranes can achieve remarkably high permeabilities while maintaining ideal selectivities by relying on homogeneous internal structures in the form of membrane proteins. In new research, a team of scientists led by Penn State University and the University of Texas at Austin applied such design strategies to desalination polyamide membranes.

Dr. Enrique Gomez, Dr. Manish Kumar and their colleagues from Iowa State University, Penn State University, the University of Texas at Austin, DuPont Water Solutions, and Dow Chemical Co. found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes.
