					<description><![CDATA[Researchers at the Harbin Institute of Technology have printed a 24 mm butterfly wing-inspired metamaterial that absorbs 21.9 times more impact energy than a standard honeycomb, swallows over 90% of radar power across most of the 2-40 GHz band and traps 90% of sound energy in the 600-900 Hz engine drone range, all at 36.9% of the thickness of conventional multi-material stacks.]]></description>
