• ITMO Physicists Found New Way to Optimize Nanoparticles and Light Interaction

  ITMO scientists have been the first to describe new features of dielectric nanoparticles’ optical response using an improved method for electromagnetic field analysis that can take into account more complex configurations of bias currents inside the objects. These effects allow to better understand the processes in nanoparticles and adjust their behavior for more efficient light control in devices such as nanolasers or sensors. The results have been published in Laser and Photonics Reviews and selected as materials for the issue cover.

• Russian Scientists Conduct Research on European XFEL

  The European XFEL is a research facility with the most powerful X-ray laser in the world, which provides scientists with ultrashort X-ray flashes, allowing them to observe chemical reactions, decipher the structure of complex biological objects and solve other topical tasks. Russian researchers had already participated in the European XFEL’s projects, but only as part of an international research group. In October 2018, a group of scientists from ITMO University gained independent access to the facility’s equipment and conducted research on a new class of materials.

• Scientists Create First Topological Nanostructures Which Make Infrared Light Visible

  An international group of physicists has developed a topological nanostructure that converts infrared radiation into green light. It is represented by zigzag arrays of silicon nanodisks with diameters of 500 nanometers placed on a glass substrate. The results have been published in Nature Nanotechnology.

• Innovative Method for Microcirculation Diagnosis Gives New Insights into Migraines

  Russian scientists developed a new optical method for non-invasive diagnosis of blood circulation in capillaries. The method is based on video recording of the skin surface with simultaneous registration of light absorption by red blood cells. Using this method, scientists found out that people suffering from migraines displayed malfunctions in capillary regulation. This technique can also be applied to studies of strokes and diabetes, as well as for monitoring blood circulation during brain surgeries. The results are published in The Journal of Headache and Pain.

• Scientists Develop Improved Model for Study of Zika Virus

  An international research team has developed a new animal model used to study the pathogenesis of the Zika virus. Scientists were able to make the disease develop in mice in a way that is similar to what happens in humans. The new model reflects the most dangerous manifestation of the Zika virus: infection of the fetus from a pregnant woman, which leads to developmental problems. Such an advancement was achieved due to a new, more pathogenic virus strain, as well as a specially bred group of mice with a human-like immune response. The new model paves the way for more detailed study of the Zika virus, which should result in a more effective fight against it. The research is published in Cell Host & Microbe.

• ITMO PhD Student on Doing Medical Modeling at University of Sheffield

  Can computer modeling help us solve problems of people suffering from cardiovascular diseases? Scientists from ITMO University in collaboration with colleagues from the Netherlands and the United Kingdom have been conducting research over the last few years to reduce the risk of complications after coronary stenting. These stents are special dilating frames that are placed in the coronary vessels and are designed to restore blood supply to the heart. Pavel Zun - a PhD student at ITMO University’s The High-Performance Computing Department and one of the project’s authors - spent the last month at the University of Sheffield, where he worked with biologists on a model for tissue growth inside the vessel after the stent is installed. He shared some details about the research with ITMO.NEWS and explained why design of computer models for medicine is one of today’s most promising areas of work.

• ITMO Researchers Study the Prospects of Switching to Driverless Transport

  The rapid development of driverless vehicles makes it quite possible that in the coming decades, the role of drivers in transport will gradually peter out. ITMO’s researchers decided to model a situation  when all private transport in St. Petersburg is replaced by autonomous cars that work as taxis. It turned out that the amount of taxis necessary to meet the city’s transport demand is ten times less than the number of private cars in the city, the average ride through the city will take about 16 minutes, and the wait time for 85% of the rides will be less than 10 minutes. Valentina Solovyova, staff member for ITMO's “Optimal Transport Systems” Laboratory expanded on the research in an interview for ITMO.NEWS.

• DataArt Reveals The Face Of A "Typical Programmer"

  Surely, you know well the stereotype of “typical” programmer who is bearded, gloomy and always wearing a sweater? And though Steve Wozniak doesn’t look anything like Linus Torvalds, much like thousands of IT-specialists are really different from their colleagues in the way they look, most people would still use the same old attire when thinking of how a programmer looks like. Still, does one’s profession really affect one’s outward appearance? This is the question that specialists from DataArt, an international company that focuses on design, development, and support of IT solutions, tried to answer. Having analyzed several thousands of photographs featuring developers from eight different countries, the project’s authors succeeded in creating the portrait of a typical programmer.
