A group of scientists from 17 countries, formed by researchers of the Universidad de Granada, has proved that the sources of the most energetic particles ever detected do not come from directions uniformly distributed in the firmament, but they aim at areas in which there are galaxies with active nuclei in the centre from a relatively close distance.

Scientists of the Pierre Auger Collaboration have announced in Malargüe (Mendoza, Argentina) that the Active Galactic Nuclei are probably responsible for the most energetic particles or cosmic rays that reach the Earth, thanks ...
Water or food of natural origins (from plants or animals) that we consume on a daily basis can contain unwanted ‘supplies’ for our organism, such as pesticides or antibiotics. A doctoral thesis carried out by Jorge Juan Soto Chinchilla, from the Department of Analytical Chemistry at the University of Granada (Universidad de Granada), and directed by professors Ana María García Campaña and Laura Gámiz Gracia, proposes new analysis methods for the detection of pesticide residue (carbamates) and antibiotic residue (sulfonamides) in water, plant foods and food of animal origin (...
José Rivera Utrilla and Manuel Sánchez Polo, who are both scientists from the department of Inorganic Chemistry of the University of Granada, have designed a material that can dispose of 100 % of the halide ions such as bromide, iodide and chloride in the water used for human consumption. Under certain conditions, the presence of these ions gives the water undesired properties and, in the worst case scenario, they cause the creation of highly toxic by-products during the water purification process.

Water chlorination has played an essential role in public health, since it has protected us from infectious diseases ...
