Manipulating chromosomes in living cells reveals that they are fluid

For the first time, scientists have been able to act physically on chromosomes in living cells. By subjecting the chromosomes to different forces using magnets, they discovered that chromosomes are in fact very fluid - almost liquid - outside cell division phases.

New method to promote biofilm formation and increase efficiency of biocatalysis

The researchers identified a library of synthetic polymers and screened them for their ability to induce biofilm formation in E. coli, a bacterium that is one of the most widely studied micro-organisms, and commonly used in biocatalysis.

Programming pH

Researchers have developed a technique to control pH at the local level, creating a dense array of microsites where the amount of protons is 100 to 1000 times higher than the average in the rest of the solution.

Scientists engineer living biosensors to track the genetic activity of cells

Researchers have developed a tool that logs a cell's genetic activity for days at a time. The biological device, named a Retro-Cascorder, records data within strands of DNA, which can then be analyzed at any time to get the cell�s activity log.

Evolutionary model predicts partitioning of molecules within cells

Scientists have developed a new theoretical method to study mixtures consisting of many different molecules. They analyzed how the molecules interact to reliably form different droplets, as happens continuously in living cells. With this model, particular droplet formation based on many interacting molecules can be predicted for the first time.
