A forest in South Carolina, a supercomputer in Ohio and some glow-in-the-dark yarn have helped a team of field ecologists conclude that woodland corridors connecting patches of endangered plants not only increase dispersal of seeds from one patch to another, but also create wind conditions that can spread the seeds for much longer distances.

Footbridges, also commonly known as pedestrian bridges, used to link two areas are nowadays becoming beautiful works of engineering and architecture that add visual value to a landscape. While often wondrous to look at, these small structures can come at a high price if not constructed in a key location or if designed with typical materials.

Community levels of air pollution significantly reduce physical activity levels in Americans according to a new study published in PLOS One. The association of air pollution with physical inactivity was particularly strong in normal weight individuals as opposed to obese people. The study, carried out by researchers in the Uniformed Services University and The Unites States Air Force School of Aerospace Medicine, correlated levels of airborne pollutants including particulate matter and ozone with leisure-time physical inactivity in adult Americans.

Increasing energy efficiency in buildings requires substantial coordination between design engineers and architects. Researchers at Princeton University applied a common structural form-finding technique to predict the equilibrium shapes and elastic energies of dielectric elastomer minimum energy structures (DEMES).

In a surprising new finding, researchers have discovered that bacterial movement is impeded in flowing water, enhancing the likelihood that the microbes will attach to surfaces. The new work could have implications for the study of marine ecosystems, and for our understanding of how infections take hold in medical devices.

The widespread loss of forest to sugarcane fields on the island of Mauritius has forced kestrels living there to survive by speeding up their life histories, according to a report published online on February 20 in the Cell Press journal Current Biology. By getting an earlier start, the birds are managing to have just as many offspring, even though they die sooner.
