Can bleach help solve the origin of life in the primordial soup?
A chemical found in hair bleach may help answer questions about the origins of life and explain why new life does not emerge on modern Earth.
How stick insects honed friction to grip without sticking
When they're not hanging upside down, stick insects don't need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort required to 'unstick' again with every step.
Gecko-inspired adhesion is self-cleaning and reliable
Geckos outclass adhesive tapes in one respect: Even after repeated contact with dirt and dust do their feet perfectly adhere to smooth surfaces. Researchers of the KIT and the Carnegie Mellon University, ...
Reliance on social groups for answers pre-empts motivation for independent analytical thinking
