Saharan silver ants use hair to survive Earth’s hottest temperatures
In a study published online June 18 in the journal Science, the researchers demonstrate how the ant’s uniquely shaped silver hairs work across an extremely broad range of the electromagnetic spectrum to reflect sunlight and shed heat. The findings could lead to biologically inspired coatings for passive radiative cooling of objects such as buildings, vehicles or even clothing.

Mantis Shrimp Inspires New Body Armor and Football Helmet Design
The mantis shrimp is able to repeatedly pummel the shells of prey using a hammer-like appendage that can withstand rapid-fire blows by neutralizing certain frequencies of “shear waves,” according to a new research paper by University of California, Riverside and Purdue University engineers.

Researchers grind nanotubes to get nanoribbons
A simple way to turn carbon nanotubes into valuable graphene nanoribbons may be to grind them, according to research led by Rice University. The trick, said Rice materials scientist Pulickel Ajayan, is to mix two types of chemically modified nanotubes. When they come into contact during grinding, they react and unzip, a process that until now has depended largely on reactions in harsh chemical solutions.
