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.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
