Swiss researchers have produced a map of the global economic structure, showing the intricate, interconnectedness among companies, similar to the relationships found in nature. This article was covered by The Huffington Post, NewScientist, and Forbes.

How do woodpeckers avoid brain injury while pecking at high speeds? Scientists reveal how the woodpecker’s unique skull structure could provide insight to more effective headgear design. Watch the slow motion video illustrating the forces experienced during a woodpecker’s pecking. This article was covered by Wired, The Independent and International Business Times

Researchers collected and analyzed data from the FDA’s Adverse Event Reporting System (AERS) database, spanning 1998 through September 2010. The results indicate that of 3,249 reported cases of suicidal/self-injurious behavior or depression, 90% reported use of varenicline, an anti-smoking drug sold under the brand Chantix.

New evidence reveals how unique vocal cord anatomy allows lions and tigers to roar loudly with little effort. Researchers previously thought that the enormous sounds were attributed to the large animal’s substantial vocal cords. However, a new study shows that this may not be the only factor. A layer of fat tissue, as well as a flat, square-shaped vocal cord, as opposed to the triangular shape found in most mammalian species, generates the terrifyingly loud and low vibrations.  This article was covered by The Smithsonian, Scientific American and The New York Times.
