Thin-film zeolite membranes with tiny, molecule-sized pores are one step closer to replacing the energy-intensive processes now used in industrial separations, a group of academic researchers is reporting.
Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.
A team of researchers from DuPont and Lehigh University has reported a breakthrough in the quest to produce carbon nanotubes (CNTs) that are suitable for use in electronics, medicine and other applications.
In an article published in the July 9 issue of Nature, the group says it has developed a DNA-based method that sorts and separates specific types of CNTs from a mixture.
The next time an overnight snow begins to fall, take two bricks and place them side by side a few inches apart in your yard.
In the morning, the bricks will be covered with snow and barely discernible. The snowflakes will have filled every vacant space between and around the bricks.
Biologists at Lehigh University and the University of Maryland have identified a cricket living in Hawaii's forests as the world's fastest-evolving invertebrate. Finicky mating behavior appears to be the driving force behind the speedy speciation of the Laupala cricket, the scientists wrote in the Jan. 27 issue of Nature magazine. Females in the Laupala genus detect tiny differences in the pulse rates of male courtship songs, which differ from one Laupala species to the next. They refuse to mate with males of other species, thus promoting the formation of new species.
The location of the recent earthquake that triggered a deadly tsunami in the Indian Ocean came as no surprise to geologists, says Anne Meltzer, a world-renowned seismologist at Lehigh University. "Earthquakes like this one happen only once every 50 to 100 years and they happen in very specific locations," says Meltzer, who has supervised two major international seismology research projects in the Himalayas.
Two physicists have produced a rainbow of visible and invisible colors by focusing laser light in a specially designed optical fiber that confines light in a glass core whose diameter is 40 times smaller than that of a human hair. The researchers are among the few scientists in the world to achieve and study the phenomenon, which is called "supercontinuum generation in nonlinear fibers."
