2/12/19 ***NO REPRO FEE*** Decarbonisation will involve most profound social transformation since the Industrial Revolution. Pictured are Dr Elizabeth Eide American Geosciences Institute, Professor Murray Hitzman Director of ICRAG, Dr Sarah Gordon University of Otago and John Thompson Cornell University. Decarbonisation will involve the most profound social adjustments and transformations since the Industrial Revolution. That’s according to Professor Murray Hitzman, Director of iCRAG the SFI Research Centre for Applied Geosciences at the iCRAG2019 conference - Resources for a Sustainable Future - which is taking place in Dublin today. The conference brings together 250 members of the academic geoscience community as well as industry and government to deliver insights into future directions for Irish geoscience research and how the geoscience research sector can play a leading role in addressing the Climate Action Plan and Ireland's commitments to the UN Sustainable Development Goals.

Climate change is known to be dominantly caused by the increased concentration of greenhouse gases in the atmosphere, in particular CO2. To prevent excessive accumulation of CO2 in the atmosphere and the perturbation of natural carbon cycles, carbon capture and sequestration (CCS) is urgently needed. In this review, a brief overview is provided for both biotic and abiotic CO2 sequestration pathways. Special focus is given to sequestration approaches pertaining to clathrate hydrates. CO2 hydrate, a solid compound made of molecular CO2 enclathrated in crystalline lattices formed by water molecules, is an attractive option for long-term CO2 sequestration due to its higher density than seawater, stability below moderate oceanic/permafrost depths, low susceptibility to fluid flow perturbation when formed in sediments. This review compiles and summarizes the research efforts made on CO2 sequestration as hydrates. Various approaches of CO2 sequestration via gas hydrates are discussed, including storage in seawater, sediments under the sea floor, permafrost regions, methane hydrate reservoirs via CO2–CH4 exchange, and depleted gas fields. The technical feasibility and potential storage capacity of these approaches are analyzed. Finally, the key scientific challenges and prospects are identified and highlighted. Issues related to economics, scale-up, and relative attractiveness versus non-hydrate methods are touched upon but are not the focus of this work.

In his one-hour Archive interview, John Walsh discusses his start in the hotel business and speaks openly about the kidnapping of his son, Adam. Walsh shares how he was approached by producers Linda Otto and Alan Landsburg to be involved with a television movie, Adam, based on Adam's kidnapping and murder. The overwhelming, positive response to the movie led to a sequel, Adam: His Song Continues, and to Walsh and his wife becoming active in getting legislation passed to aid in the recovery of missing children. Walsh discusses his initial reluctance to hosting America's Most Wanted, on the fledgling FOX network, but soon saw the huge potential of the show to assist in the capture of fugitives. He also briefly hosted a daytime talk show, The John Walsh Show, and continues to fight for the creation of a national DNA Database. Walsh was the recipient of the prestigious Governors Award at the 2011 Creative Arts Emmys. Melody Chen conducted the interview on October 28, 2008 in North Hollywood, CA.

Glioblastoma progression involves multifaceted changes in vascularity, cellularity, and metabolism. Capturing such complexities of the tumor niche, from the tumor core to the periphery, by magnetic resonance imaging (MRI) and spectroscopic imaging (MRSI) methods has translational impact. In human-derived glioblastoma models (U87, U251) we made simultaneous and longitudinal measurements of tumor perfusion (Fp), permeability (Ktrans), and volume fractions of extracellular (ve) and blood (vp) spaces from dynamic contrast enhanced (DCE) MRI, cellularity from apparent diffusion coefficient (ADC) MRI, and extracellular pH (pHe) from an MRSI method called Biosensor Imaging of Redundant Deviation in Shifts (BIRDS). Spatiotemporal patterns of these parameters during tumorigenesis were unique for each tumor. While U87 tumors grew faster, Fp, Ktrans, and vp increased with tumor growth in both tumors but these trends were more pronounced for U251 tumors. Perfused regions between tumor periphery and core with U87 tumors exhibited higher Fp, but Ktrans of U251 tumors remained lowest at the tumor margin, suggesting primitive vascularization. Tumor growth was uncorrelated with ve, ADC, and pHe. U87 tumors showed correlated regions of reduced ve and lower ADC (higher cellularity), suggesting ongoing proliferation. U251 tumors revealed that the tumor core had higher ve and elevated ADC (lower cellularity), suggesting necrosis development. The entire tumor was uniformly acidic (pHe 6.1-6.8) ...
