How plants' threat-detection mechanisms raise the alarm

New work led by Carnegie's Zhiyong Wang untangles a complex cellular signaling process that underpins plants' ability to balance expending energy on growth and defending themselves from pathogens. These findings, published ...

Developing wet circuits for biology research

You don't have to be an engineer to know that water and electronics don't mix. But if you want to use a sensing circuit to study small-scale features in a community of cells, the electronics must find a way to accommodate ...

How mice choose the best escape route

Escaping imminent danger is essential for survival. Animals must learn a new environment fast enough for them to be able to choose the shortest route to safety. But how do they do this without ever having experienced threat ...

Cooling speeds up electrons in bacterial nanowires

The ground beneath our feet and under the ocean floor is an electrically-charged grid, the product of bacteria "exhaling" excess electrons through tiny nanowires in an environment lacking oxygen.

Researchers create self-assembled logic circuits from proteins

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital circuits that take advantage ...

Extraterrestrial mining would emulate 'tears of wine' phenomenon

Tears of wine is a phenomenon frequently observed as a ring of wine formed near the top of the glass generates droplets that fall back into the wine. This phenomenon can be explained by the Marangoni effect driven by the ...

Ranking nanodevice functionality methods

As the demand for nanodevices grows so too does the need to improve the functionality of such devices, which is vulnerable to changes in the charge distribution, energy levels or conformation. Hence the desire to assess the ...
