(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 ...

(Via LIGO and UIB) The LIGO Scientific Collaboration has made a third detection of gravitational waves. As was the case with the first two detections, the waves were generated when two black holes merged to form a larger black hole. LIGO is a group of more than 1200 researchers from more than 100 scientific institutions, spread over four different continents. From 2002, the Relativity and Gravitation Group from the Universitat de les Illes Balear ...

(Via Universitat de Barcelona) The research group leaded by Xavier Barril, user of the Spanish Supercomputing Network, has developed a more efficient computational method to identify new drugs. The study, published in the scientific journal Nature Chemistry , proposes a new way of facing the discovery of molecules with biological activity. Since it is based on a different approach, this method complements conventional tools and allows going fo ...

(Via ICIQ) The research group of Núria López has published a paper in Nature Materials explaining how massive simulations prove that certain surfaces are more disordered than previously thought. Prof. Núria López is a researcher in the Institut Català d’Investigació Química (ICIQ) and user of the Spanish Supercomputing Network. Surface terminations are responsible for the chemical and physical properties of materials. Understanding ...

(Via IFIMAC) A group of Spanish and French researchers has described in the journal Science the first real-time observation of the birth and subsequent evolution of an electronic wave packet. In addition to providing the first ‘movie’ of the electron wave packet dynamics, and of the interferences that such dynamics implies, the high degree of control and high temporal resolution achieved by the study opens the door to the design of electro ...
