An experiment which forced E. coli bacteria to adapt or perish showed that, in a pinch, they were capable of improvising a novel molecular tool to save their skins.
"The bacteria reached for a tool that they had, and made it do something it doesn’t normally do," said James Bardwell, an associate professor of molecular, cellular and developmental biology at the University of Michigan. "We caught evolution in the act of making a big step."
This big step also turns out to be a new way of making molecular bolts called disulfide bonds, which are of particular interest to the biotechnology industry. Disulfide bonds are stiffening struts in proteins that also help the proteins fold into their proper, functional, three-dimensional shapes.

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
