Polymer Passage Takes Time

Rice University researchers have created a theoretical method to calculate the time it
takes long-chain polymers to pass through nano-sized pores in membranes. The researchers studied how membrane pore geometry affects the translocation of long polymers. They say the new method, which appears this month in the Journal of Chemical Physics, works for pores of any geometry, whether they're straight, conical or made of joined cylinders of different sizes.

Public immunization efforts may be
much more sensitive than previously realized to small changes in the perceived costs or risks of vaccination, scientists at Harvard University report this week. In some cases, the spread of vaccine avoidance via social networks can make the difference between a minor, localized outbreak and an epidemic four times as large.

Researchers in the lab of Pulickel Ajayan, Rice
University's Benjamin M. and Mary Greenwood Anderson Professor in Mechanical Engineering and Materials Science and of chemistry, have figured out how to make sheets of h-BN, which could turn out to be the complementary apple to graphene's orange.

A borrowed boat, a
small mountain lake and the inaugural run of a half-a-million-dollar, state-of-the-art multi-beam sonar system made history this month with the successful high-definition mapping of the bottom of Fallen Leaf Lake, a tributary lake just upstream from Lake Tahoe.

15,000 Beams of Light

One Chicago skyline is dazzling enough. Now imagine 15,000 of them. Northwestern University
researchers have done just that--drawing 15,000 identical skylines with tiny beams of light using an innovative nanofabrication technology called beam-pen lithography (BPL). BPL uses an array of pens made of a polymer to print patterns over large areas with nanoscopic through macroscopic resolution.

After years of concentrated effort, scientists from the North Greenland Eemian Ice Drilling (NEEM) project hit bedrock more than 8,300 feet below the surface of the Greenland ice sheet last week. The project has yielded ice core samples that may offer valuable insights into how the world can change during periods of abrupt warming.
Led by Denmark and the United States, and comprised of scientists from 14 countries, the NEEM team has been working to get at the ice near bedrock level ...

With its vast 1.5 million acres of mangrove swamps, sawgrass prairies and subtropical jungles, could the Florida Everglades--the famous river of grass--be affected by the Gulf oil spill?
While current estimates are that little if any oil entered the Loop Current or reached the Everglades, this area is a significant national natural resource, and to study the effects of the spill on seagrasses and mangrove forests in and near the Everglades, the National Science Foundation ...

Paleontologists scouring a river bank in Tanzania have unearthed a previously unknown crocodile from 105-million-year-old, mid-Cretaceous rock in the Great East African Rift System.
The discovery of a relatively lanky, cat-sized animal with mammal-like teeth and a land-based lifestyle supports a growing consensus that crocodiles were once far more diverse than they are today, dominating ecological niches in the Southern Hemisphere during the Cretaceous Period that were filled in the ...
