U.S: Tracking the virus in wastewater is helping respond to the most recent wave of the coronavirus, but a more coordinated national effort is needed, experts sa

As the highly contagious Omicron variant pushes national coronavirus case numbers to record highs and sends hospitals across the country into crisis mode, public health officials are eagerly searching for an indication of how long this surge might last.

The clues are emerging from an unlikely source: sewage.

People who contract the coronavirus shed the virus in their stool, and the virus levels in local wastewater provide a strong, independent signal of how much is circulating in a given community.

The sewage data reveal an Omicron wave that is cresting at different times in different places.

Researchers Make Progress Toward High-Performing Water Desalination Membranes

Sat, 2021-01-02 23:17 — mike kraft

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.
