Biologists Discover Unique Properties of MiR-93-5p MicroRNA in Prostate Cancer
Researchers at the International Laboratory of Microphysiological Systems of the HSE Faculty of Biology and Biotechnology investigated how different isoforms of the same microRNA influence gene function in prostate adenocarcinoma. The study found that in some cases, microRNAs can reinforce each other’s effects by targeting and suppressing the same genes. This finding offers a fresh perspective on the molecular mechanisms underlying tumour development and on the search for disease biomarkers. The results have been published in PeerJ.

HSE Economists Use Search Queries to Forecast Birth Rates
Researchers from the HSE Faculty of Economic Sciences have shown that the accuracy of birth rate forecasts for Russia can be improved by almost 50% by incorporating the dynamics of online search queries related to pregnancy and childbirth into forecasting models. In the best-performing models, the forecasting error fell from 4.6% to 3.2%. The findings have been published in Populations and Economics.

Особенности поведения микроволнового излучения активных областей на Солнце перед корональными выбросами массы

С. 15–18.
Bakunina I. A., Мельников В. Ф., Абрамов-Максимов В. Е., Моргачев А. С., Шаин А. В.

Solar flares and coronal mass ejections (CME) are the most powerful manifestations of solar activity. Both phenomena associated with the evolution of the spatial structure of the magnetic field of active regions (AR). It is known that not all powerful flares accompanied by CME. In some cases, CME are observed, associated with very low intensity bursts. At the same time, the observational signs that determine the ability of AR to cause the eruption of matter from AR into the high layers of the solar corona are still not clear. This makes it difficult to understand the physical mechanism of eruption initiation (CME trigger). The purpose of this work is to search for observational signs of the onset of the eruptive process. For this, we conducted a comparative analysis of pre-flare and flare conditions for 6 flare events, accompanied by CME, and 5 events not accompanied by CME.

Взаимное расположение магнитных жгутов и источников микроволнового излучения в эруптивных вспышках
И.А. Бакунина, В.Ф. М., А.В. Ш. et al., Геомагнетизм и аэрономия 2025 Т. 65 № 9 С. 1363–1373
Рассмотрена связь особенностей положения и ориентации магнитных жгутов в активной области (АО) с источниками микроволнового (17 ГГц) излучения и излучения в крайнем ультрафиолетовом диапазоне (EUV) при возникновении эруптивных вспышек, сопровождающихся корональными выбросами массы, и вспышек с "запертой" эрупцией. Приведены примеры эруптивных событий, демонстрирующие пространственное совпадение микроволновых источников с расположением магнитных жгутов в АО, восстановленных при ...

Spatial Position of Magnetic Flux Ropes in Flare Active Regions with and without Coronal Mass Ejections
I. A. Bakunina, Melnikov V. F., Shain A. V. et al., Geomagnetism and Aeronomy 2024 Vol. 64 No. 8 P. 1237–1249
Using statistics from 15 X-ray class M flare events, the features of the position and orientation of magnetic flux ropes in the general spatial structure of the magnetic field of the active region (AR) during flares and coronal mass ejections (CME) were studied by reconstructing the coronal magnetic field from the photosphere to the corona ...

Preflare Fluctuations of Radio Emission from Active Regions of the Sun According to Observations at RSTN
Abramov-Maximov V. E., Bakunina I. A., Geomagnetism and Aeronomy 2024 Vol. 64 No. 7 P. 1054–1058
For the first time, several flare events are analyzed based on multifrequency observations using the Radio Solar Telescope Network. The purpose of the analysis is to identify signs of flare preparation. In all considered cases, preflare quasi-periodic fluctuations (QPFs) of radio emission were detected. The duration of preflare wavetrains is 6–20 min. Wavetrains consist of 3–5 pulses. QPFs ...

It is shown on a sample of 15 M-class X-ray flares that CMEs occur in events with «open» magnetic ropes reconstructed in the NLFFF approximation. Magnetic ropes coincide with radio brightness maxima at 17 GHz. Several hours before the flare, in the region of magnetic ropes, a glow of loops in the EUV (94, 131 ...

The dynamics of the magnetic field reconstructed in the nonlinear force-free approximation in the pre-flare and post-flare phases of M-class X-ray flares in seven active regions is considered: two flares with a coronal mass ejection (CME), two flares with eruption but no CMEs, and three flares without eruption.

We present a study of the frequency of occurrence of quasi-periodic fluctuations (QPFs) of microwave radiation from solar active regions at the pre-flare stage. We used correlation curves obtained with the Nobeyama Radioheliograph (NoRH). We analyzed 529 flares of classes X, M, and C (according to the GOES classification). In a significant number of considered events (approximately 75% ...

P.A.Bespalov, O.N.Savina, Geomagnetism and Aeronomy 2023 Vol. 63 No. 7 P. 910–915
According to modern concepts, Type I noise storms in the meter wavelength range (30–400 MHz), consisting of a large number of narrow-band short bursts, are excited in the rarefied solar corona. These radiations are characterized by a high brightness temperature and circular polarization. Despite many advances in theory and confidence that the mechanism of radiation ...
