Seeing 'living' nanofibers in real time

The Greek goddess Psyche borrowed help from ants to sort a room full of different grains. Cells, on the other hand, do something similar without Olympian assistance, as they organize molecules into robust, functional fibers. ...

Investigation of simple model cells resolves deformation mechanisms

Living cells must alter their external form actively, otherwise functions like cell division would not be possible. At the Technical University of Munich (TUM) the biophysicist Professor Andreas Bausch and his team have developed ...

Herschel reveals a ribbon of future stars

Star formation is taking place all around us. The Milky Way is laced with clouds of dust and gas that could become the nursery of the next generation of stars. Thanks to ESA's Herschel space observatory, we can now look inside ...

A new model for how twisted bundles take shape

In the current issue of Nature Materials, polymer scientists Greg Grason, Douglas Hall and Isaac Bruss at the University of Massachusetts Amherst, with Justin Barone at Virginia Tech, identify for the first time the factors ...

Research team identifies key step in process of Shigella infection

Researchers from the Massachusetts General Hospital (MGH) Division of Infectious Diseases are investigating the mechanism by which several important pathogenic species of bacteria deliver proteins into the cells of the organisms ...

World's first parallel computer based on biomolecular motors

A study published this week in Proceedings of the National Academy of Sciences reports a new parallel-computing approach based on a combination of nanotechnology and biology that can solve combinatorial problems. The approach ...

Black holes banish matter into cosmic voids

We live in a universe dominated by unseen matter, and on the largest scales, galaxies and everything they contain are concentrated into filaments that stretch around the edge of enormous voids. Thought to be almost empty ...
