Researchers predict that this summer, the planet may once again approach its maximum rotation speed. The causes of this acceleration are not fully understood, and there is still no definitive scientific explanation. Leonid Zotov, Professor at the School of Applied Mathematics, MIEM HSE, notes that if, in the past, the so-called ‘leap second’ was added on New Year’s Eve, then for the first time in history, the question has arisen about whether it is time to subtract one.

This year marks the 10th anniversary of the HSE International Preparatory Year programme. The programme offers a one-year foundation course for international applicants preparing to enter Russian universities. HSE lecturers help future students acquire the knowledge and skills needed to successfully undertake a degree programme in Russia.

Researchers from the International Laboratory of Dynamical Systems and Applications at the HSE Campus in Nizhny Novgorod have developed a theory that enables a mathematical proof of robust chaotic dynamics in networks of interacting elements. This research opens up new possibilities for exploring complex dynamical processes in neuroscience, biology, medicine, chemistry, optics, and other fields. The study findings have been accepted for publication in Physical Review Letters, a leading international journal. The findings are available on arXiv.org.

On June 5, 2025, the top projects were presented as part of the Digital Solutions Marathon hackathon in a case study on forecasting and evaluating lost sales. First place went to a joint team of students from the HSE Faculty of Computer Science and the National University of Science and Technology MISIS, consisting of six students.

In 1968, American mathematician Paul Chernoff proposed a theorem that allows for the approximate calculation of operator semigroups, complex but useful mathematical constructions that describe how the states of multiparticle systems change over time. The method is based on a sequence of approximations—steps which make the result increasingly accurate. But until now it was unclear how quickly these steps lead to the result and what exactly influences this speed. This problem has been fully solved for the first time by mathematicians Oleg Galkin and Ivan Remizov from the Nizhny Novgorod campus of HSE University. Their work paves the way for more reliable calculations in various fields of science. The results were published in the Israel Journal of Mathematics (Q1).

The AI and Digital Science Institute at the HSE Faculty of Computer Science hosted a conference focused on cutting-edge recommender system technologies. In an atmosphere of active knowledge sharing among leading industry experts, participants were introduced to the latest advancements and practical solutions in recommender model development.

On June 27, 2025, the Faculty of Economic Sciences at HSE University hosted a delegation from the School of Economics at Shanghai University, a partner of the Faculty of Economic Sciences and the International College of Economics and Finance. The main goal of the meeting was to discuss the prospects for expanding cooperation between the partners, specifically the development of academic exchange and the organisation of joint events for students and faculty from both the School of Economics and the Faculty of Economic Sciences.

The XII Russian-Chinese Summer School on International Relations has opened at HSE University. This year’s theme is ‘Facets of the World Majority: Practice and Narratives.’ The school has brought together 27 master's and doctoral students as well as early-career researchers from leading universities in China and Russia.
