Glycogen is the key energy storage molecule in humans, animals and fungi. It’s where the glucose that fuels us is stored and release from. However, the precise mechanisms by which glycogen is formed at its very start have remained unclear until now. A recent study published in Nature uncovers how the enzyme that initiates glyconeogenesis works at a molecular level. The research was carried out by a team of the Institute of Theoretical and Compu ...

(Via ICN2) Heat transfer fluids are widely used as coolants in vehicles and industrial processes to dissipate heat and prevent overheating. However, the cooling potential of current fluids based on water and oils is typically too low to meet the ever more demanding needs of industry. In microelectronics, for instance, absolute temperature control is crucial for the adequate and reliable performance of electronic components. Additionally, new equa ...

(Via Phys.org) For the first time, physicists have developed a method to visually image the entanglement between electrons. As these correlations play a prominent role in determining a molecule's wave function—which describes the molecule's quantum state—the researchers then used the new method to produce the first images of the square of the two-electron wave function of a hydrogen (H2) molecule. Although numerous techniques already exist ...

Efficient energy transport in dense matter by laser-driven relativistic electron beams is crucial in many applications including the study of warm dense matter, inertial confinement fusion, and ion acceleration by laser. A recent research, which counted with the participation of the RES user Javier Honrubia (ETSIAE-UPM), demonstrates the relativistic electron beam transporting efficiently its energy in dense plasma with an externally imposed stro ...

(Via ICIQ) Alcohols and sugars are among the main derivatives of non-edible biomass. The transformation of these molecules into hydrogen or other chemicals by reforming technologies could lead to a more sustainable future. However, hydrogen production from long-chain alcohols has a very complex reaction networks. Even a simple alcohol like ethylene glycol goes through 75 intermediates and 250 different possible reactions. Understanding this mecha ...

(Via IAC) Researchers at the Instituto de Astrofísica de Canarias (IAC) have identified, using the Gran Telescopio de Canarias (GTC) one of the first stars formed in the Milky Way, which is a key to the formation of the first chemical elements in the Galaxy. The calculations needed to carry out this study were executed in the RES supercomputer LaPalma. The results of this research were published in the scientific journal The Astrophysical Journa ...

(Via ScienceNode) Turbulence is present in most fluids, like the ocean currents, the air around aircraft wings, the blood in our arteries or smoke from chimneys. Since turbulence is so prevalent, its study has many industrial and environmental applications. For instance, scientists model turbulence to improve vehicle design, diagnose atherosclerosis, build safer bridges, and reduce air pollution. Caused by excess energy that cannot be absorbed ...

(Via Nanotechweb and UCM) A new work published in the journal Nature Nanotechnology could be the basis to create faster and smaller electronic devices. The research has been carried out by researchers from the Materials Physics department of the UCM and the Institute of Materials Science of Madrid (ICMM-CSIC), users of RES resources, With the aim of keeping on with the fast pace of increase in storage capacity and computer speed (characterized ...

(Via CNB-CSIC) A study published in the journal PNAS describes what happens at the atomic level when a double-stranded nucleic acid molecule is stretched. Using computer simulation, scientists found a way to explain why DNA coils when it is stretched, whereas double-stranded RNA unwinds. If a DNA molecule is stretched, it will coil up on itself. If the same is done with an RNA double helix, it will unwind. Why do they behave so differently alt ...

(Via Universitat de Barcelona). Sugar or carbohydrate synthesis is important for the development of diagnostic tests, vaccines and new drugs. In a study co-led by a team of the Department of Inorganic and Organic Chemistry and the Institute of Theoretical and Computational Chemistry of the UB (IQTCUB), together with a research group of biological chemistry of the University of Oxford, have synthetized carbohydrates with enzymes through a reaction ...
