Europium is a rare-earth metal responsible for the pure red glow in displays and other luminescent materials. For a long time, however, it refused to emit light when surrounded by certain organic molecules known as acylpyrazolone ligands. Chemists have now uncovered the reason: in europium complexes with these ligands, a 'black window' appears—a charge-transfer state in which the energy absorbed by the ligand is dissipated as heat rather than emitted as light. Understanding this mechanism opens the way to designing more efficient red-emitting materials for displays, fluorescent thermometers, and chemical sensors. The results have been published in Dalton Transactions.

June 27, 2026, marks three years since the launch of CubeSX-HSE-3, the third research satellite developed by HSE University. Equipped with an AIS system designed for operation in the Arctic, the satellite has completed more than 16,500 orbits of the Earth (covering approximately 720 million kilometres), operated for over 26,000 hours, and transmitted data more than a thousand times. It has captured over 150 images of the Earth, and these figures continue to grow.

Lucas Akolzin, from Brazil, is a third-year student of the International Programme 'International Relations and Global Studies.' In his interview with the HSE News Service, he spoke about why he decided to pursue education in international relations, what political leaders inspire him, and how his Russian background encouraged him to study in Moscow.

HSE researchers examined the careers of 600,000 graduates of Russian secondary vocational education programmes and found that at the start of their careers, the gender wage gap reaches 23%, doubling after three years. This disparity is largely due to male and female students choosing different occupations when enrolling in vocational schools. These were the findings made by Sergey Roshchin, Natalya Yemelina, and Ksenia Rozhkova from of the HSE Faculty of Economic Sciences. The article has been published in Educational Studies.

The annual Positive Psychology Day took place at Muzeon Arts Park (Moscow), organised by the University Open to the City project and the HSE Faculty of Social Sciences. More than 500 participants gathered to discuss a question that concerns everyone: how to maintain inner balance when the world around us is changing faster than we can adapt.

This year, Elizaveta Zorina is completing her Master’s degree in Artificial Intelligence Hardware and Software at the HSE Tikhonov Moscow Institute of Electronics and Mathematics (HSE MIEM). In autumn 2025, she spent six months in China as part of an academic mobility programme. In this interview, she shares her experience of studying at the School of Information Science and Engineering at Shandong University.

Chemists from HSE University have discovered a way to carry out a reductive addition reaction without using an external reducing agent. Instead, the required 'resource' is supplied by the aldehyde itself, one of the reaction participants. This approach helps prevent unwanted side reactions, reduces toxicity, and simplifies the production and synthesis of organic molecules, including those used in the manufacture of medicines. The study has been published in Journal of Catalysis.

Researchers from the Cognitive Health and Intelligence Centre at HSE University conducted the first-ever systematic review of studies on the specifics of emotion-from-motion perception in autism. The review showed that differences found between autistic and non-autistic individuals are largely associated with the experimental design and the types of tasks given to study participants. The review findings have been published in Research in Autism.

In early June, the Science Republic initiative of the Centre for Student Academic Development presented popular science projects at the Science and Ice Cream Festival at VDNKh. On June 5, 13, and 14, HSE University ran an extensive programme of events, from lectures to intellectual games. The events took place at the BIOTECH Museum, Museum of Urban Economy of Moscow, and Smart City pavilions.
