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.

Algae bloom covers northern Lake Pontchartrain

Large areas of Lake Pontchartrain are now covered with algae that may be the so-called blue-green version, which are often toxic and can cause a variety of health effects in humans and pets, officials with the Lake Pontchartrain Basin Foundation announced Monday (March 26).

That conclusion is based on aerial photographs taken by Patrick Quigley with Gulf Coast Air Photo, and observations by boaters, both of which found a large area of green to blue-green material on the surface of the lake along the North Shore and on both sides of the northern third of the Lake Pontchartrain Causeway.

Blue-green algae is actually made up of cyanobacteria, which can produce a variety of toxins -- or poisonous substances -- that can affect the liver, kidney and the reproductive system, and can cause abdominal pain, headaches, sore throats, nausea, diarrhea,  pneumonia, tingling or burning sensations, numbness, drowsiness, and respiratory paralysis, according to the Environmental Protection Agency.
