1. Scientists from the Peter the Great St. Petersburg Polytechnic University, the First St. Petersburg State Medical University. I.P. Pavlova(PSPbGMU) and the Institute of Macromolecular Compounds of the Russian Academy of Sciences have developed a matrix that can be used as a vascular implant. They implanted her into the abdominal aorta of laboratory rats and observed her for 16 months. During this time, an artificial vessel was formed in place of the matrix, very similar to the real one.

2. Scientists from the St. Petersburg University ITMO, together with colleagues from the Institute of Physics of Microstructures of the Russian Academy of Sciences, will develop a research methodology and methods for producing compact emitters(subwavelength resonators) of a new type. The main advantage of such compact emitters is the ability to be placed on the elements of common silicon electronics, thus creating a new type of smooth interface between optical and electrical systems.

3. Russian scientists have developed a new method for diagnosing liver neoplasms based on optical technologies. It consists in the use of a special fine-needle probe through which light enters the tissues, and then the collection of reflection and fluorescence signals carrying diagnostic information occurs. With more accurate tumor detection, doctors can improve the speed and effectiveness of treating patients with liver cancer.

4. Researchers at the Hybrid Photonics Laboratories in Skoltech and Southampton(UK), in collaboration with Lancaster University(UK), have demonstrated a new optical method to synthesize artificial solid-state crystal structures for cavity-polaritons using only laser light. The results could be useful in a variety of applications from optical based communications and information processing, to high sensitivity detectors for biomedical purposes and topologically protected lasing.

5. In addition to preparing a joint Venera-D mission with the United States, Russia plans to develop its own program, as announced on Tuesday to reporters at the HeliRussia-2020 exhibition by the head of Roscosmos Dmitry Rogozin.
