Tiny pump builds polyrotaxanes with precision

Northwestern University researchers have developed the most precise way to build polyrotaxanes, a mechanically locked polymer for slide-ring gels, battery electrode materials and drug-delivery platforms.

Chemists fabricate novel rewritable paper

First developed in China in about the year A.D. 150, paper has many uses, the most common being for writing and printing upon. Indeed, the development and spread of civilization owes much to paper's use as writing material.

Simulating how the Earth kick-started metabolism

(Phys.org) —Researchers have developed a new approach to simulating the energetic processes that may have led to the emergence of cell metabolism on Earth – a crucial biological function for all living organisms.

Unexpected allies help bacteria clean uranium from groundwater

(Phys.org) —Since 2009, SLAC scientist John Bargar has led a team using synchrotron-based X-ray techniques to study bacteria that help clean uranium from groundwater in a process called bioremediation. Their initial goal ...

Mimicking nature, scientists can now extend redox potentials

(PhysOrg.com) -- New insight into how nature handles some fundamental processes is guiding researchers in the design of tailor-made proteins for applications such as artificial photosynthetic centers, long-range electron ...

Researchers demonstrate control of living cells with electronics

E. coli bacteria and an electronic device might seem to have little in common, but in a recent experiment, University of Maryland researchers linked them into the first closed-loop system able to communicate across the technological–biological ...
