• ITMO Researchers Develop Algorithm for Rapid DNA Analysis

  Scientists from ITMO University have unveiled Strainy, an algorithm that identifies DNA bacteria within microbiomes and discerns between heterogenous strains with a high degree of accuracy. With the help of this software, researchers should be able to quickly determine the pathogenicity and antibiotic resistance of specific bacterial communities, as well as learn more about their evolutionary paths. The corresponding paper has been published in Nature Methods.

• ITMO Physicists Simplify Thin Film Anodization for Allergy Diagnostics

  Researchers from ITMO’s International Research and Educational Center for Physics of Nanostructures have simplified the synthesis of thin films based on anodic aluminum oxide: the process now takes two minutes instead of seven hours and can be used to produce films with specific optical properties. The new method can be applied in sensors for allergy diagnostics, affordable solar cells, and beam splitters for laser distance meters and spectral devices. The method was described in a paper published in Optical Materials.

• ITMO Scientists Create Cheaper Carbon Dot-Based LEDs

  Researchers from ITMO University have found a simple and cheap way to produce bright light-emitting diodes (LEDs) using carbon dots treated with polyethylene glycol during synthesis. Nanoparticles produced in this way demonstrate brighter photoluminescence with no additional energy demands and can be used to create stable diodes that are as bright as their more challenging-to-produce analogs. The study was described in a paper published in Small Structures.

• Classification From ITMO To Help AI Generate Random Noise on Request

  Random noise is useful for generating truly random numbers, such as for stronger passwords and data protection, but it’s also what helps reconstruct full-scale images obtained from small cameras placed within the body during medical screenings. Using machine learning and fractal analysis methods, researchers from ITMO University have studied a source of random noise – the textures inside a layer of liquid crystal – and created a classification based on the analysis of large- and small-scale fractal dimensions. Using this data, it's possible to train a neural network to select the parameters for random noise generation, adjusting it for various purposes. The results of the study have been published in Journal of Molecular Liquids.

• ITMO Physicists Twist Electrons for Particle Accelerator Experiments

  Researchers from ITMO University are the first to have found a way to twist electrons with a laser beam, opening up a path towards experiments with twisted electrons in particle colliders – a feat previously considered impossible. The discovery will make it possible to learn more about the structure and behavior of protons and neutrons that make up atom nuclei, as well as look into the nature of quarks, some of the smallest known matter particles. The results of the study are described in a paper published in Physical Review A.

• More Lung Cancer Cases Discovered Thanks to Computer Tomography

  In the late 2010s, there was a surge in lung cancer incidence in Russia – however, there wasn’t a related rise in death rate. According to a team of researchers from ITMO headed by oncoepidemiologist Anton Barchuk, this can be explained by the spread of computer tomography for screening and diagnostics. Their study was published in Cancer Epidemiology.
