Paving the way for methane hydrate formation on metal–organic frameworks (MOFs)

The presence of a highly tunable porous structure and surface chemistry makes metal–organic framework (MOF) materials excellent candidates for artificial methane hydrate formation under mild temperature and pressure conditions (2 °C and 3–5 MPa). Experimental results using MOFs with a different pore structure and chemical nature (MIL-100 (Fe) and ZIF-8) clearly show that the water–framework interactions play a crucial role in defining the extent and nature of the gas hydrates formed. Whereas the hydrophobic MOF promotes methane hydrate formation with a high yield, the hydrophilic one does not. The formation of these methane hydrates on MOFs has been identified for the first time using inelastic neutron scattering (INS) and synchrotron X-ray powder diffraction (SXRPD). The results described in this work pave the way towards the design of new MOF structures able to promote artificial methane hydrate formation upon request (confined or non-confined) and under milder conditions than in nature.

New Orleans, Louisiana Census tracks and blocks, 1960 (Image 2 of 2) (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: New Orleans, Louisiana, by census tracts and blocks: 1960. It was published by The Census Bureau ca. 1960. Scale [ca. 1:17,500]. This layer is image 2 of 2 total images of the two sheet source map. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Louisiana State Plane Coordinate System, South NAD83 (in Feet) (Fipszone 1702). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, or other information associated with the principal map. This map shows features such as Census block and tract numbers and boundaries, roads, canals, drainage, and more. Includes inset and legend. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

Paving the Way for Micro-, Small- and Medium-Sized Enterprises in the Southern Mediterranean. CEPS Policy Brief No. 314, 14 January 2014

The upheavals of the Arab Spring in the southern Mediterranean led to domestic and international demands on the governments in the region to implement reforms aimed at enhancing business and investment conditions especially for micro, small- and medium-sized enterprises (MSMEs), which carry out an overwhelming majority of the region’s economic activity. A comprehensive survey among some 600 high-growth potential MSMEs in Algeria, Egypt, Morocco and Tunisia identified and ranked the key obstacles impeding their high-growth potential. This Policy Brief summarises the main results and policy recommendations that can be drawn from this survey, which has been analysed in depth by Ayadi & De Groen (2014).

The European Court of Justice blocks the EU’s accession to the ECHR. CEPS Commentary, 8 January 2015

The goal of accession to the European Convention of Human Rights (ECHR) is to place the EU under the external oversight of the specialised court in Strasbourg. But in its Opinion of 18 December 2014 the Luxembourg-based European Court of Justice ruled that the draft accession agreement is not compatible with the EU treaties. In this commentary the authors argue that this would force EU member states to renegotiate the terms of accession to the ECHR. But meeting the demands made by the Court of Justice will prove to be very difficult.

The proteasome inhibitor MLN-273 blocks exoerythrocytic and erythrocytic development of Plasmodium parasites.

Protein degradation is regulated during the cell cycle of all eukaryotic cells and is mediated by the ubiquitin-proteasome pathway. Potent and specific peptide-derived inhibitors of the 20S proteasome have been developed recently as anti-cancer agents, based on their ability to induce apoptosis in rapidly dividing cells. Here, we tested a novel small molecule dipeptidyl boronic acid proteasome inhibitor, named MLN-273 on blood and liver stages of Plasmodium species, both of which undergo active replication, probably requiring extensive proteasome activity. The inhibitor blocked Plasmodium falciparum erythrocytic development at an early ring stage as well as P. berghei exoerythrocytic progression to schizonts. Importantly, neither uninfected erythrocytes nor hepatocytes were affected by the drug. MLN-273 caused an overall reduction in protein degradation in P. falciparum, as demonstrated by immunoblots using anti-ubiquitin antibodies to label ubiquitin-tagged protein conjugates. This led us to conclude that the target of the drug was the parasite proteasome. The fact that proteasome inhibitors are presently used as anti-cancer drugs in humans forms a solid basis for further development and makes them potentially attractive drugs also for malaria chemotherapy.
