High-pressure cryocooling of protein crystals reveals gas transport channels in a hydrogen-converting enzyme

28-06-2016

Networks of hydrophobic tunnels transport substrate and inhibitory gases (i.e. oxygen) to/from the active sites of NiFe hydrogenases. Here, the tunnel network of an oxygen-tolerant NiFe hydrogenase has been mapped by combining single-crystal X-ray diffraction with the...

Let there be light: how silver clusters in nano-cages produce light

24-06-2016

Future LEDs might have been partly brewed at the ESRF’s beamline DUBBLE. An international team of researchers has shown that highly luminescent clusters of silver atoms can be assembled in the porous framework of minerals known as zeolites. The high efficiency of light...

The puzzle of the changing nanogold

14-06-2016

Sometimes scientists become detectives in their research, like in this story. Take an evasive nanogold cluster’s structure, a newly-developed investigative approach and three synchrotrons in different continents and you have a plot. And four years later, an outcome,...

Phonon-mediated passive transport in lipid membranes

13-06-2016

Through an experiment at the ESRF, scientists from Brookhaven National Laboratory have found evidence for propagating in-plane transverse phonon modes in a DPPC lipid membrane. These transverse phonon modes exhibit phononic gaps upon temperature increase, providing...

Iridescent flexible films see the light of day

03-06-2016

Stacking microscopic marbles into regular layers produces intriguing materials that scatter light in such a way that they produce intense colours. A team led by the University of Cambridge and including scientists from Germany, the Netherlands and Japan, has invented...

In search of the missing xenon

30-05-2016

The noble gases, also called rare gases, such as xenon, are the most inert atomic group, but can become reactive under extreme conditions. An international team of scientists used a combination of several synchrotron techniques and ab initio modelling to investigate...

3D structure sheds light on the mechanism of uromodulin self-polymerisation

30-05-2016

Urinary tract infection is the most common non-epidemic bacterial infection in humans. The urinary tract lacks a mucus layer to shield it against infections and mammals produce a molecular net that captures pathogenic bacteria in the urine and clears them from the body....

Fate of silver nanoparticles in agricultural soils amended with sewage sludge

23-05-2016

Silver nanoparticles released from consumer products end up in waste water treatment plants and may then be transferred to agricultural soils through the use of sewage sludge as fertiliser. Results from this study challenge the current idea that silver nanoparticles...

Nanoparticle uptake in worms

17-05-2016

This image shows a 3D rendering of the tiny roundworm Caenorhabditis elegans, which was exposed to cobalt nanoparticles in soil and then fixed in a quartz capillary. C. elegans is a model organism for exposure experiments because it has a short lifecycle and, being...

Experimental realisation of single-atom magnets

10-05-2016

The existence of single-atom magnets has been proven by X-ray magnetic circular dichroism. Monodisperse holmium atoms adsorbed on a nonmagnetic MgO thin film display magnetic hysteresis up to a temperature of 30 K and with magnetic relaxation time of the order of 1500...

09-05-2016

Norovirus, a highly contagious stomach bug, affects millions of people of all ages around the world. There are very few ways to prevent infections and the disease can be dangerous for babies, since they can quickly become dehydrated. Researchers have shown that components...

Getting to the heart of fossils

29-04-2016

Scientists have discovered, for the first time, a fossilised heart in a 119 million-year-old fish from Brazil called Rhacolepis. This has been possible thanks to the powerful X-rays of the ESRF, the European Synchrotron Radiation Facility, Grenoble, France. This breakthrough...
