Choreographed origami: folding ribosomal RNA studied at EMBL, ILL and IBS

Building ribosomes – the cell’s protein factories – is like a strictly choreographed dance. Other ‘machines’ inside the cell have to produce specific RNA molecules and fold them into the right shape, then combine the folded RNA with proteins to form a working ribosome.  The study combined nuclear magnetic resonance experiments performed at EMBL and neutron scattering experiments performed at the ILL in Grenoble, France.

ESRF and ILL: X-rays and neutrons open new paths for energy scavenging

Harvesting unused energy has been the object of research since the days of the windmill and the waterwheel. In recent years, thermo-electric materials have enabled the re-use of otherwise wasted thermal energy as electrical power. Driven by the quest to efficiently cool densely packed micro-electronics chips, they are also used as solid-state refrigerators. One of the difficulties involved in developing thermo-electric systems that convert heat into electric current is the need for materials exhibiting high electrical conductivity but low thermal conductivity, which is only possible with complicated crystal structures. Scientists have now discovered a way of suppressing thermal conductivity in sodium cobaltate, opening new paths for energy scavenging.

X-rays reveal uptake of nanoparticles by soya bean crops

Metals contained in nanoparticles can enter into the food chain. Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analysed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant tissue. The results contribute to the controversial debate on plant toxicity of nanoparticles and whether engineered nanoparticles can enter into the food chain.

Breast cancer scans possible with a 25 times reduced radiation dose

Synchrotron X-rays confirm a new method for X-ray image processing.

Scientists have developed a way to produce three-dimensional X-ray images of the breast at a radiation dose that is lower than the 2D radiography methods used in clinics today. The new method enables the production of 3D diagnostic computed tomography (CT) images with a spatial resolution 2-3 times higher than present hospital scanners, but with a radiation dose that is about 25 times lower.

Myoglobin can perform without water

Understanding will help protein’s potential application in biochemical gas sensors or in state-of-the-art wound dressing.
Proteins do not need to be surrounded by water to carry out their vital biological functions, according to scientists from the IBS and the ILL, along with the University of Bristol, the Australian National University, the Forschungszentrum Jülich.  Knowing that proteins can function outside of water opens them up to use in real life applications because it shows that there are other alternatives if water is unavailable.

Quasi-crystals as studied on the epn science campus

Congratulations to Daniel Shechtman on the award of his Nobel Prize for Chemistry! Shechtman's discovery of quasicrystals was an extremely important step in fundamental solid-state chemistry and physics, and it has changed the way we see crystals and long range order.

There has been substantial related work done in this area both with neutrons at the ILL and with x-rays at the ESRF. Marc de Boissieu, a CNRS researcher at SIMAP (CNRS/Grenoble INP/ UJF), has been leading for more than 20 years now cutting-edge experiments on the structure and dynamics of quasi-crystals. “Although progress has been made, much remains to be done to understand  fascinating quasicrystals and the related complex metallic alloys”, says de Boissieu.

Precise measurements of cholesterol transport rates give new hope for Alzheimer’s treatment

Neutrons have shown the movement of cholesterol between and within cells takes far longer than previously thought. Findings could impact the treatment of a range of diseases linked to abnormal rates of cholesterol transfer.

Scientists using neutron scattering at the Institut Laue Langevin (ILL) and at the NIST Center for Neutron Research have discovered that cholesterol moves far slower within and between cells than previously thought. Their findings reveal how different concentrations of cholesterol within cells are maintained and shed light on severe disorders linked to cholesterol transport abnormalities, including Alzheimer’s, which may help in their treatment.

Identification of the Elusive Hydronium Ion Replacing a Proton in an Enzyme

A  collaborative effort between scientists at the ILL, Los Alamos National Laboratory, Keele University, ISIS, and the University of Toledo has resulted in the remarkable observation of hydroxonium ions that are thought to be involved in proton transfer during enzyme-catalysed reactions.

The work, which used ILL's D19 diffractometer, exploits the remarkable ability of neutron diffraction to visualise hydrogen atoms and therefore to be able to distinguish between hydroxonium ions and water molecules - this is typically impossible using X-ray crystallography.  The enzyme studied was xylose isomerase - this is an enzyme of high biological and biotechnological significance, and one where changes in the location of hydrogen atoms are crucial to catalytic activity that is associated with converting D-xylose to D-xylulose. It turns out that hydroxonium ions replace metal ions and may be involved in the templating specific sites for the binding of metal ions. The work explains how the activity of the enzyme decreases dramatically at low pH.

IBS : Intrinsic disorder in measles virus nucleocapsids

Researchers of the IBS, in collaboration with their colleagues of the UVHCI and the AFMB, report the first in situ observation of the intrinsically disordered domain of the nucleoprotein of measles virus.

Using nuclear magnetic resonance spectroscopy, small angle scattering, and electron microscopy, they have obtained a structural characterization of the intrinsically disordered C-terminal domain of the nucleoprotein in the context of the entire N-RNA capsid. Their results, published online by PNAS, suggest that this intrinsically disordered part plays an important role in infection by measles virus.
