Consumers of content about serial killers watch and read it to experience intense emotions that are often lacking in everyday life and to understand the reasons that drive people to commit crimes. However, such content does not contribute to increased aggression. These conclusions were drawn by sociologists from HSE University. The results of their study have been published in Crime, Media, Culture: An International Journal.

Researchers at HSE University's St Petersburg School of Economics and Management have been exploring methods for the efficient allocation of resources in systems involving multiple players. The scientists have proven the existence of strategies for optimal decision-making in competition for limited, discrete resources in four different cases. The developed mathematical model can be applied in various fields, ranging from education and medicine to managing networks and computing power. The paper has been published in Games and Economic Behaviour.

A team of researchers at HSE University investigated the neural mechanisms involved in how the brain processes persuasive messages. Using functional MRI, the researchers recorded how the participants' brains reacted to expert arguments about the harmful health effects of sugar consumption. The findings revealed that all unpersuaded individuals' brains responded to the messages in a similar manner, whereas each persuaded individual produced a unique neural response. This suggests that successful persuasive messages influence opinions in a highly individual manner, appearing to find a unique key to each person's brain. The study findings have been published in PNAS.

Researchers have proposed using polymer membranes modified with copper, zinc, and chromium metal ions for water purification. These polymers were used for the first time in water purification via electrodialysis. Copper-based membranes demonstrated record selectivity for monovalent ions, opening new possibilities for sustainable water recycling. The study has been published in the Journal of Membrane Science. 

Researchers at HSE MIEM have developed a model for calculating the electrical conductivity of aqueous electrolyte solutions; for the first time, it considers the spatial distribution of ion charges instead of assuming their localisation at a single point. The model remains effective even at high electrolyte concentrations and across a wide temperature range. This breakthrough will contribute to the development of more efficient batteries and enable the calculation of electrical conductivity without the need for experimental testing. The study has been published in the Journal of Chemical Physics.

A group of Russian scientists led by Professor Natalia Kryzhanovskaya at HSE Campus in St Petersburg has been researching microdisk lasers with an active region based on arsenide quantum dots. For the first time, researchers have successfully developed a microdisk laser coupled with an optical waveguide and a photodetector on a single substrate. This design enables the implementation of a basic photonic circuit on the same substrate as the radiation source (microlaser). In the future, this will help speed up data transfer and reduce equipment weight without compromising quality. The study results have been published in Semiconductors.
