A team of researchers at the Universitat Autònoma de Barcelona, co-ordinated by Professors Josep Egozcue and Cristina Templado, has shown for the first time that the older a man is, the more probable it is that his spermatozoa will present chromosome anomalies. This is the first time that a lineal relationship has been established with precision between these two factors. The conclusions of this study, published in the European Journal of Human Genetics, increase the importance of the father’s age in evaluating the risk of the foetus suffering from chromosomal anomalies.
The advanced age of the mother is one of the greatest risk factors in the foetus suffering from anomalies in the number of chromosomes, which leads to miscarriages and the birth of babies with physical and mental handicaps. The evaluation of the influence of the father’s age in the appearance of these anomalies, however, has always been pending. There are studies that point towards this relationship, but it has always been difficult to clearly assign the role of the father in cases with anomalies in the number of chromosomes.
A team of researchers in the Cellular Biology, Physiology and Immunology Department at the Universitat Autònoma de Barcelona, co-ordinated by Dr Josep Egozcue and Dr Cristina Templado, has looked at the research from another perspective – that of investigating the relationship between the father’s age and the chromosomes in his sperm. The objective was to thereby deduce the relationship between the father’s age and foetus anomalies.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
