Engineering Around Extreme Events

Katie-Leigh Corder, Fenella Saunders

AnaBarrosPodcast

Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.

Moving Science Towards Open Access

Katie-Leigh Corder, Katie L. Burke

Open-access research papers continue to be a debate in the world of scientific publishing. Public Library of Science (PLOS) forged the pathway for the open-access publishers and continues to be regarded as a role model for the movement's successes and challenges.

Biologist Michael Eisen, who is also one of the founders of PLOS, along with his postdoc mentor and cofounder Pat Brown, was motivated to pursue open-access publishing after discovering that the scientific community did not own their own literature.

And Then They Were Gone: Egypt’s Disappearing Wildlife

Katie-Leigh Corder, Tom Dunne, Katie L. Burke

YeakelAnimationUsing fossils and depictions in ancient art, Justin Yeakel and his colleagues reconstructed the food web of larger-bodies mammals over the past 11,000 years. As the climate became more arid and human population densities increased, the mammalian food web of Egypt lost its redundancy as more animals became locally extinct. Most notably, midsized herbivores—such as gazelles and antelope that link to the most carnivores—declined.

KosowskyImage1Click to Enlarge Image

Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.

Exploring Beneath a Painting's Surface

Katie-Leigh Corder, Katie L. Burke

FischerImage2Click to Enlarge ImageUsing laser technology called nonlinear pump-probe microscopy, Fischer and his team can study the pigments and layers to help determine, for example, the age of historic paintings. Such analysis reveals the artist’s techniques and further information about the artwork. By crossing the threshold into the art world, Fischer and his team can expand their research into new fields and assist a broader section of society in unique and scientific ways.
