How Migraines Happen: Latest Research Reveals New Details
Despite the fact that one in every seven people worldwide experiences migraines, their exact mechanisms and treatment have not been completely explained. In pursuit of a cure, researchers use nitroglycerin injections to simulate migraines in animals. Though commonly known as a vasodilator, the drug has exhibited inverse properties in a recent study conducted by three Russian universities. The findings shed light on migraine triggers, paving the way for novel treatment strategies.

ITMO Researchers Develop New Terahertz Pulse-Based Data Encoding Method
Researchers around the world are working on ways to transfer data in the terahertz (THz) range, which would make it possible to send and receive information much faster than what is allowed by today’s technology. But the issue they’re facing is that it is much more difficult to encode data in the THz range than in the GHz range, which is currently used by 5G tech. A group of scientists from ITMO University have demonstrated the possibility of modifying terahertz pulses in order to use them for data transmission. An article on this subject was published in Scientific Reports.

ITMO University Scientists Present Record Amount of Works at the 2019 Genetic and Evolutionary Computation Conference in Prague
GECCO (Genetic and Evolutionary Computation Conference), which this year took place in Prague, Czech Republic, is one of the biggest and most prestigious scientific events in the field of evolutionary computation. ITMO University scientists have been active participants of the conference since 2011, regularly presenting the results of their work to the international community. But this year, ITMO’s representation reached a record high with 11 reports, tackling both fundamental and applied aspects of evolutionary computation, being presented by the staff and students of the Information Technologies and Programming Faculty. The research by the Bachelor’s graduate Vitaly Karavaev was recognized as the best in the student section.

Researchers Investigate Correlation Between Blood Flow and Body Position
For the first time ever, an international research group detected alterations in capillary blood flow around the face caused by body position change. This became possible through the use of imaging photoplethysmography. Using this method, scientists can examine blood vessels located in the carotid system in order to, for example, investigate the cerebral blood flow response to various stimuli in health and disease. The results of the research were published in Scientific Reports.

Researchers Use Silicon Nanoparticles For Bioimaging and Drug Delivery
An international research team has studied a new cell visualisation and drug delivery system based on nanoparticles coated with luminescent dye molecules. Scientists have found out that the particle material and the distance between the dye and the particle’s surface affect the intensity of the luminescent signal. It turned out that silicon nanoparticles coated with dye molecules are more efficient than similar particles made of gold. Thanks to their biocompatibility, silicon particles can be used for cell visualisation and drug delivery. The research was published in Scientific Reports.

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.

ITMO Scientists Study Properties of Terahertz Gauss-Bessel Beams
Scientists from ITMO University became the first to conduct a comprehensive study of the spatio-temporal and spatio-spectral properties of pulsed broadband terahertz Gauss-Bessel beams. This theoretical research looks promising in terms of practical application, as these beams can be used in wireless communications to increase data transfer speed and the number of simultaneously connected devices. The research results were published in the Scientific Reports journal.

ITMO-Developed Nanoparticle Technology Helps Stop Internal Bleeding
Scientists from ITMO University have developed magnetically-driven nanoparticles containing thrombin. A drug based on these nanoparticles can be injected intravenously and delivered straight to the site of a vascular injury to stop internal bleeding. It can accelerate local clot formation and reduce overall blood loss by up to 15 times. The nanoparticles are not toxic to humans and can potentially be used for safe treatment. The results were published in Scientific Reports.
