• Scientists “Hack” Regulatory Mechanism of Immune Cell Activity

  An international research team has described new molecular mechanisms regulating the activity of macrophages, which are crucial elements of the immune response, in a breakthrough project. Macrophage activation is regulated by the level of itaconate, which has various effects on the production of substances causing inflammation. Regulatory pathways of itaconate and its derivatives are associated with the pathogenesis of some autoimmune diseases. Experiments on mice and isolated human cells have shown that these substances can significantly alleviate the symptoms of psoriasis. The results of this study are published in Nature.

• Physicists Propose New Mechanism of Radio Emission in Neutron Stars

  Young scientists from ITMO University have explained how neutron stars generate intense directed radio emission. They developed a model based on the transitions of particles between gravitational states, i.e. quantum states in gravitational field. The researchers were the first to describe such states for electrons on the surface of neutron stars. Physical parameters obtained with the developed model are consistent with real experimental observations. The results are published in The Astrophysical Journal.

• Researchers Use Nanoparticles to Study Proteins at High Temperatures

  Russian scientists have developed a multifunctional nanodevice based on dielectric nanoparticles coupled with a metal film. The device can be used to measure the temperature of surrounding molecules. Experiments have also shown that heat resistance in proteins can be increased by changing the nanoparticles’ chemical properties. The resulting nanostructures are very biocompatible, which makes them potentially useful in biomedicine. The results were published in Laser & Photonics Reviewers and the Journal of Biophotonics.

• ITMO Student Wins IEEE Undergraduate Scholarship

  This year six young scientists from the USA, Canada and Russia were awarded an IEEE MTT-S Undergraduate Scholarship. Maxim Masyukov, a fourth-year student at the Faculty of Photonics and Optical Information, was among the winners. MTT-S is the biggest international society of experts in microwave, millimeter-wave, and terahertz technologies. The society exists as part of the IEEE, the Institute of Electrical and Electronics Engineers, and provides scholarships to students and postgraduates. Maxim’s research concerned the development of a chiral metasurface with tunable polarizing properties in THz frequency range. ITMO.NEWS asked him some questions about how to win such a scholarship.

• Russian, German and French Scientists to Collaborate on Nanowhisker Research at European XFEL

  Scientists from ITMO University were granted the right to conduct an experiment on XFEL, the world's largest free-electron laser. The project will be carried out in collaboration with researchers from Germany and France. It will also be the first project at the European XFEL managed by a group of Russian scientists. The experiment is devoted to the study of nanowhiskers - nanomaterials with high spatial and energy resolution of the electronic structure and atomic formation. Among the potential applications of nanowhiskers, or threadlike nanocrystals, are various areas of electronics and medicine. Read out article to learn more about the project and its future prospects.

• ITMO Scientists Develop Topological Defect Detection Method

  An international scientific team has developed a new method of probing topological structures and their topological phase transitions. The method is based on examining the reflection spectrum of EM-waves reflecting off an object from different impact angles. The accuracy of the method’s results has been verified experimentally in both IR and microwave spectra. Results were published in Nature Communications.

• Physicists Create Crystal Lattice from Polaritons

  An international research team has produced an analog of a solid-body crystal lattice from hybrid photon-electron quasiparticles - polaritons. In the resulting polariton lattice, certain particles’ energy does not depend on their speed. At the same time, the lattice’s geometry, particle concentration and polarization properties can still be modified. This opens up new perspectives for study of quantum effects and the use of optical computing. Results of the study were published in Physical Review Letters.

• Scientists Invent Method of Catching Bacteria with ‘Photonic Hook’

  An international team of physicists has discovered a new type of curved light beams, dubbed a “photonic hook”. Photonic hooks are unique, as their radius of curvature is two times smaller than their wavelength. This is the first time that such a small curvature radius of electromagnetic waves has been recorded. A photonic hook can be used to improve the resolution of optical scanning systems, as well as to control the movement of nanoparticles, individual cells, viruses or bacteria. Results of this research were published in Optics Letters and Scientific Reports.
