Creation without contact in the collisions of lead and gold nuclei

 E-Mail IMAGE: Semicentral or central collisions of lead nuclei in the LHC produce quark-gluon plasma and a cocktail with contributions of other particles. Simultaneously, clouds of photons surrounding the nuclei collide, resulting. view more  Credit: Source: IFJ PAN When heavy ions, accelerated to the speed of light, collide with each other in the depths of European or American accelerators, quark-gluon plasma is formed for fractions of a second, or even its cocktail seasoned with other particles. According to scientists from the IFJ PAN, experimental data show that there are underestimated actors on the scene: photons. Their collisions lead to the emission of seemingly excess particles, the presence of which could not be explained.

Fabiola Gianotti, Leader of European Nuclear Council

Fabiola Gianotti, Leader of European Nuclear Council Italian physics is the first woman to lead the European Council for Nuclear Research (CERN) in Geneva. The Woman Post | Carlex Araujo Listen to this article Your browser does not support the audio tag. This professional sector is dominated by just over 80% of men, where it has been very difficult to change that trend. In this sense, of incompatibility of the career with motherhood, and despite policies to promote the female presence in scientific careers, the percentages of scientists in these sectors barely move. Therefore, having Fabiola Gianotti directing with her leadership and communication skills, even with simplicity and humility, is considered to be and will be a positive example for young women who may consider following a scientific career, as expressed by Cristina Manuel Hidalgo, scientific researcher of the Higher Council for Scientific Research (CSIC) and author of the web portal Research and Science.

University of Tartu ranks among the world s top in materials science | Science

These updates are republished press releases and communications from members of the Science|Business Network University of Tartu ranks among the world’s top in materials science According to the recently updated Web of Science citations database, the University of Tartu now also ranks in the one percent of the world’s most highly cited research institutions in the field of materials science. This is the thirteenth field of research in which the University of Tartu belongs among the top institutions. Materials science is a rapidly developing field of research at the intersection of modern physics, chemistry and engineering, with the operational goal of developing new materials for different fields, such as photonics, electronics, energy and transport.
