Fitting a right hand in a left-handed mitten

Many biomolecules come in two versions that are each other's mirror image, like a left and a right hand. Cells generally use the left-hand version of amino acids to produce proteins, and uptake mechanisms were thought to ...

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.

Determining what binds to mucus

The human body is full of mucus. This viscous goo isn't just a nuisance that gets coughed up or sneezed out—it can bind to drugs, toxins or microbes, potentially impacting human health. However, relatively little is known ...

Renaissance for artisanal mortar

To adapt mortar to new building materials and industrial methods, the content in walls and plaster changed during the 20th century. The change meant that knowledge of historical materials and methods for producing mortar ...

Mechanism of iron-based hydrogen bond cleavage revealed

Hydrogen-based fuel cells hold promise for sustainable power generation, but to become practical they need to be more efficient and cost effective. Scientists at Pacific Northwest National Laboratory's (PNNL's) Center for ...
