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.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
