Igor Ivanov (CFTP, Instituto Superior Tecnico, Lisbon) will give at DLNP a lecture course on neutrino mass models. The lectures will start with basics on Dirac and Majorana neutrinos and their mass terms and will proceed with various tree-level and radiative examples of the seesaw mechanism. Then, after a gentle introduction to the theory of finite groups, an example will be shown of how symmetry-based lepton sectors shape the PMNS mixing matrix.

On 29 October at 17:00 the lecture “Memory and Learning: How It Works” will be given by Asya Kazantseva at the Blokhintsev Universal Library with support from DLNP.

A popular science journalist Asya Kazantseva will speak about the latest achievements in neurobiology and experimental psychology. What allows memorizing more information? Is it possible to get rid of fears? Why is the seashell an ideal object for studying memory mechanisms?

In the past decades, neurobiologists have seriously advanced in understanding processes that occur in the brain as one learns new information. They can already rewrite memories in the experiments on rats and dim emotions of the past in volunteers. At what moment can people recall everything and is it necessary? What techniques are even now able to improve preparation for seminars, lectures, and exams?

For the first time in the scientific inquiry of a star, our Sun, measurement of the stellar power at the moment of its production has been achieved by the Borexino collaboration which announced their results in an article published today by the prestigious, interdisciplinary, scientific journal Nature.

This very important achievement was obtained by detecting solar neutrinos, which are produced by nuclear reactions deep within the Sun, and which then pass right through the Sun, taking just over eight minutes to reach the Earth. Until now, all solar energy measurements were based on light from the Sun's photosphere - the familiar sunlight which lights up our skies and warms the Earth. But the energy carried by this sunlight was produced in solar fusion reactions about 100,000 years ago – the average time for energy to percolate from the central regions of the Sun and reach its surface.

Russian science, the Joint Institute for Nuclear Research have suffered an irredeemable loss. Venedikt Petrovich Dzhelepov,an eminent Russian scientist and organizational leader of science, a corresponding member of the Russian Academy of Sciences, who devoted over 60 years of his fruitful work to atomic nucleus and elementary particle physics,technology, and applications of powerful accelerators, died on 12 March 1999 at the age of 85.

V.P. Dzhelepov, renowned Russian scientist, was one of the founders of the Institute of Nuclear Problems (1948) and later of the Joint Institute for Nuclear Research in Dubna, where he was director (1956-1988) and since 1988 honorary director of the Laboratory of Nuclear Problems.
