What's Not to Like About Butterflies?

Katie L. Burke

2015-05SpotlightBurkeF1.jpgClick to Enlarge Image A snippet of conversation as associate editor Katie L. Burke interviews Erik Aschehoug about what finds compelling and what others may find compelling about his work to conserve the rare, cryptic butterfly called the Saint Francis satyr.

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.

Expanding with the Cosmos

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.

The Many Personalities of Animals

Katie-Leigh Corder, Fenella Saunders

AndySih

Have you ever wondered whether animals have personalities the way people do? Dr. Andy Sih, a professor of ecology at the University of California, Davis, researches animal personalities and shows that traits, such as an individual’s level of aggressiveness versus passivity, can impact an individual’s survival as well as the well-being of its surrounding group. Dr. Sih's work on insects even has implications for understanding how human behaviors are controlled by personality.

From Balloons to Space Stations: Studying Cosmic Rays

Katie-Leigh Corder, Fenella Saunders

CREAM Inflating

Cosmic rays have mysterious qualities about them that scientists continue to research in order to better understand their origins and composition. Dr. Eun-Suk Seo, a professor of physics at the University of Maryland, and her colleagues, fly enormous balloons as large as a football stadium and a volume of 40-million-cubic feet for extended periods over Antarctica to reach as close to the top of the atmosphere as possible. The instruments in the balloons can then record the particles coming from cosmic rays before they break up in the atmosphere. Dr. Seo further explains how her work can help humans understand the origins of cosmic rays and why they are so highly energetic.

Behind the Porpoise's Echolocation

Katie-Leigh Corder, Lee Miller, Fenella Saunders, Jamie L. Vernon, Magnus Wahlberg

2015-01WahlbergF1.jpgClick to Enlarge ImagePorpoises navigate through their environment, find prey, and avoid potential dangers with biological sonar, or echolocation clicks. These clicks are one of the most high-pitched signals produced by any animal. The time between the released clicks and the returning echo tells the porpoise the distance and location of the nearby object. If this object is prey, the porpoise will close in on it. The closer the porpoise gets the more clicks it will release. The click rate increases to several hundred clicks-per-second right as the prey is captured.

From Biology to Military History: Patterns in Animal Weaponry

Katie-Leigh Corder, Katie L. Burke, Sandra J. Ackerman

EmlenBookCoverWhat are the parallels between an ancient war ship and a dung beetle? More than you would think, actually! Douglas J. Emlen, PhD, a professor in the Division of Biological Sciences at the University of Montana, has a unique perspective on animal weaponry.

When he started to examine how humans engaged in warfare throughout time, Dr. Emlen discovered a consistent pattern that connects all the way back to animal weaponry. The pattern is so striking that he has made it the focus of his new book, Animal Weaponry: The Evolution of Battle.

Revealing the Logic Behind Candy Crush

Katie-Leigh Corder, Fenella Saunders, Toby Walsh

2014-11WalshF2.jpgClick to Enlarge Image In this animation, Candy Crush is turned into a model electrical circuit, which can be used to structure the equivalent of a logic puzzle. Besides justifying Candy Crush addictions, this information could be used to harness the player power of this game for bigger concerns, including computer security. Watch the behind-the-scenes movements and how it is truly a logic puzzle.

Hydrangea Colors: It’s All in the Soil

Katie-Leigh Corder, Fenella Saunders, Henry Schreiber

The Hydrangea macrophylla (big-leafed hydrangea) plant is the only known plant that can 'detect' the pH level in HydrangeaAnimationsurrounding soil!

One of the world’s most popular ornamental flowers, it conceals a bouquet of biological and biochemical surprises.  The iconic “snowball” shaped hydrangea blooms are a common staple of backyard gardens.

Hydrangea colors ultimately depend on the availability of aluminum ions(Al3+) within the soil.
