Bringing information into the cell

Researchers at the Paul Scherrer Institute (PSI) have elucidated an important part of a signal pathway that transmits information through the cell membrane into the interior of a cell.

New sensor detects rare metals used in smartphones

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds ...

DNA managed like climbing rope to avoid knots

A process that cells use to unravel knotted strands of DNA – resembling a method used to control climbing ropes – has been uncovered by scientists.

Taming the genome's 'jumping' sequences

The human genome is fascinating. Once predicted to contain about a hundred thousand protein-coding genes, it now seems that the number is closer to twenty thousand, and maybe less. And although our genome is made up of about ...

Multiple modes for selectivity of transmembrane transport

LMU researchers utilized a biophysical approach to understand how bacterial import proteins bind and selectively convey their cargoes across membranes. The results reveal an unexpectedly wide variety of transfer mechanisms.
