Research & Expertise News at HSE University

Scientists at HSE University have discovered that in preeclampsia—one of the most severe complications of pregnancy—the placenta remodels its lipid metabolism, reducing its own cholesterol synthesis while increasing cholesterol transfer to the foetus. This compensatory mechanism helps sustain foetal nutrition but accelerates placental deterioration and may lead to preterm birth. The study findings have been published in Frontiers in Molecular Biosciences.

HSE researchers evaluated the accuracy of technology forecasts in the transportation sector over the past 50 years and found that the average accuracy rate does not exceed 25%, with the lowest accuracy observed in aviation and rail transport. According to the scientists, this is due to limitations of the forecasting method and the inherent complexities of the sector. The study findings have been published in Technological Forecasting and Social Change.

A team of scientists, including researchers from HSE University, has proposed a method for assessing stress resilience using physiological markers derived from wearable devices and saliva samples. The participants who adapted better to stress showed higher heart rate variability, higher zinc concentrations in saliva, and lower potassium levels.  The findings were published in the Journal of Molecular Neuroscience.

HSE researchers have found that the likelihood of quitting smoking rises with increasing financial struggles. While low levels of financial difficulties do not affect smoking behaviour, moderate financial stress can increase the probability of quitting by 13% to 21%. Responses to high financial stress differ by gender: men are almost 1.5 times more likely to give up cigarettes than under normal conditions, whereas no significant effect is observed on women’s decisions to quit smoking. These conclusions are based on data from the Russia Longitudinal Monitoring Survey (RLMS-HSE) for 2000–2023 and have been published in Monitoring of Public Opinion: Economic and Social Changes. 

Researchers from the HSE Center for Language and Brain and the Mental Health Research Centre have proposed a new method of linguistic analysis that enables the distinction between normal and pathological ageing. Using this approach, they showed that patterns in patients’ word choices during verbal fluency tests allow clinicians to more accurately differentiate clinically significant impairments from subjective memory complaints. Incorporating this type of analysis into clinical practice could improve the accuracy of early dementia diagnosis. The results have been published in Applied Neuropsychology: Adult.

Career prospects in Russia prove to be more important for African students than climate, language barriers, or everyday difficulties. HSE researchers came to this conclusion after analysing survey results from students representing 28 countries across the continent. The key factor influencing their decision is the opportunity to start working while still studying.

On March 19, Academician and Professor Andrey Yaroslavtsev, Head of the Joint Department of Inorganic Chemistry and Material Science with the RAS Kurnakov Institute of General and Inorganic Chemistry, celebrated his birthday. To mark the occasion, he spoke with the HSE News Service about protons, membranes, and other areas of his research.

By 2030, the global education system will need 44 million new teachers. Schools have already started rehiring retired teachers and issuing licenses for accelerated programmes. Experts from the HSE University Institute of Education have analysed the educational policies of almost 50 countries and published the report ‘World Education Policy—2025.’
