A protein mines, sorts rare earths better than humans, paving way for green tech      (via sciencedaily.com)     Original source 

Rare earth elements, like neodymium and dysprosium, are a critical component to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth's crust and from one another. Scientists have discovered a new mechanism by which bacteria can select between different rare earth elements, using the ability of a bacterial protein to bind to another unit of itself, or 'dimerize,' when it is bound to certain rare earths, but prefer to remain a single unit, or 'monomer,' when bound to others.

Source-shifting metastructures composed of only one resin for location camouflaging      (via sciencedaily.com)     Original source 

Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.

Watch these cells rapidly create protrusions for exploration and movement      (via sciencedaily.com)     Original source 

In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
