ANCHORAGE, Alaska (Reuters) - Earth’s ice is melting faster today than in the mid-1990s, new research suggests, as climate change nudges global temperatures ever higher.

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.

At dawn, people began to gather, quietly planning for survival after Hurricane Irma.

They started with the grocery stores, scavenging what they needed for sustenance: water, crackers, fruit.

But by nightfall on Thursday, what had been a search for food took a more menacing turn, as groups of people, some of them armed, swooped in and took whatever of value was left: electronics, appliances and vehicles.
