September-October 2015
Volume 103, Number 5

Oil rigs, such as this one in the North Sea off the Scottish coast, are often subjected to pummeling ocean waves. Other powerful waves, such as seismic and magnetic ones, can also cause great damage. Researchers are exploring concepts from cloaking technology that might be used to protect structures or objects from such waves...


FEATURE ARTICLES

The Most Powerful Movements in Biology

S. N. Patek

From jellyfish stingers to mantis shrimp appendages, it takes more than muscle to move extremely fast.


The Past and Future Space Suit *

David P. Cadogan

These single-occupant spacecraft enable human exploration outside of Earth’s atmosphere, and new designs and materials promise even greater functionality.


Do Humans Possess a Second Sense of Hearing? *

Neil Todd

The cochlea is a recent evolutionary development. Mammalian ears, including our own, still also rely on features from our early vertebrate ancestors.


A Protective Cloak Against Earthquakes and Storms *

Gregory J. Gbur

Invisibility cloaking is not close on the horizon, but shielding from other types of damaging waves may be more feasible.
