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.

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.

Turning an old enemy into a helpful friend

Half our genome is basically foreign, derived from viruses. Obviously, the invasion of such foreign elements can deregulate critical biological processes, and lead to disease. This is why animals, including humans have evolved ...

New method to create ultrafast 3-D images of nanostructures

Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyse complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. ...

Can we cure cancer by finding out how two proteins interact?

In a paper published in the Journal of Biological Chemistry, Dr. Özdemir has studied two protein families named Rho GTPases and IQGAPs, which are known to play an important role in cancer metastasis. These two "suspicious" ...
