Kinetics and RNA sequence dependence of measles virus nucleocapsid

Measles virus RNA genomes are packaged into helical nucleocapsids (NCs), comprising thousands of nucleo-proteins (N) that bind the entire genome. N-RNA provides the template for replication and transcription by the viral polymerase and is a promising target for viral inhibition. The nucleocapsid assembly process regulating this process has been described for the first time by IBS researchers thanks to a combination of real-time NMR, fluorescence spectroscopy and electron microscopy. This observation is reported in Angewandte Chemie on June 06. More on the IBS website

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.

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.

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.

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.

Le Lorem Ipsum est simplement du faux texte employé dans la composition et la mise en page avant impression. Le Lorem Ipsum est le faux texte standard de l'imprimerie depuis les années 1500, quand un peintre anonyme assembla ensemble des morceaux de texte pour réaliser un livre spécimen de polices de texte. Il n'a pas fait que survivre cinq siècles, mais s'est aussi adapté à la bureautique informatique, sans que son contenu n'en soit modifié. Il a été popularisé dans les années 1960 grâce à la vente de feuilles Letraset contenant des passages du Lorem Ipsum, et, plus récemment, par son inclusion dans des applications de mise en page de texte, comme Aldus PageMaker.

PSB Student day

On the 7th of March 2016, the eight edition of the PSB student day was opened with a seminar on “Broadly neutralizing HIV-1 antibodies” by group leader Pascal Poignard who recently joined the Institut de Biologie Structurale (IBS), followed by a presentation from Matthias Haffke (Novartis, Switzerland), highlighting the various career opportunities which exist for post-doctoral fellows, especially in industry.

Throughout the day, the IBS Seminar room has seen second and third year PhD students: Benjamin Brocco (ILL), Etienne Raimondeau (EMBL), Charles Arnaud (IBS) and Xuelei Lai (ESRF) giving talks about their research projects.

A large audience attended the event and took the opportunity to discuss around posters during the lunch and coffee breaks in a friendly atmosphere.

During two clip sessions, 17 first year PhD students introduced themselves and their work. The afternoon session was closed by a presentation from Timothé Flenet (IMAG, Grenoble), highlighting the diverse opportunities which exist for pre and post-docs to create they own start-up.

The day’s proceedings were drawn to a close with the usual prize ceremony for the Best Poster and Best Clip. Best poster prize was awarded to Marko Nedeljkovic (IBS) and Best Clip prize went to Sylvain Aumonier (ESRF).

On behalf of the PSB student committee, I would like to sincerely thank our PSB scientific coordinator, Florent Bernaudat, for his precious help.

 

Congratulations to all the participants who took part and we look forward to seeing you next year!
