Uncovering the tricks of nature's ice-seeding bacteria

Like the Marvel Comics superhero Iceman, some bacteria have harnessed frozen water as a weapon. Species such as Pseudomonas syringae have special proteins embedded in their outer membranes that help ice crystals form, and ...

Ribosome research takes shape

In a new state-of-the-art lab at SLAC National Accelerator Laboratory, components of ribosomes – tiny biological machines that make new proteins and play a vital role in gene expression and antibiotic treatments – form ...

Atomic insights into how plant steroid hormone makes plants grow

If one wants to better understand how plants grow, one must analyse the chemistry of life in its molecular detail. Michael Hothorn from the Friedrich-Miescher-Laboratory of the Max Planck Society in Tübingen and his team ...

Hybrid material as gold-leaf substitute

(Phys.org) —A team of researchers headed by Professor Raffaele Mezzenga has created a hybrid material out of gold and milk proteins that looks like a wafer-thin gold leaf. Thanks to its properties, it could be used in a ...

A long-sought goal: Crystallizing an elusive protein

(Phys.org) —Plants use an enzyme known as "rubisco" to capture carbon dioxide from the atmosphere and, with energy from the sun and nutrients from the soil, build up the shoots, leaves, and stems that make up the plant ...

First-ever determination of protein structure with X-ray laser

(Phys.org) —An international team of researchers, including LLNL physicist Matthias Frank and postdoc Mark Hunter, have for the first time used an ultra-intense X-ray laser to determine the previously unknown atomic-scale ...

Researchers develop chemically specialised germanium surface

Researchers at the Ruhr Universität Bochum have developed a new method for attaching proteins to the surface of germanium crystals – for the first time also membrane proteins. This enables time-resolved tracking of the ...
