Chemists of the Ural Federal and Volgograd State Medical Universities have created a compound that suppresses the growth of cancer cells. A new powerful substance can become the basis for antitumor drugs, as it affects the pathology that leads to the development of such malign...
SCIENTISTS HAVE DEVELOPED BIODEGRADABLE NONWOVENS FOR ACCELERATED WOUND HEALING
2023-01-06 19:42
Wound healing is a complex, multi–stage process that can be accompanied by complications. Despite the abundance of wound treatment methods and a variety of dressings, the development of safe and effective materials for regenerative medicine that do not require replacement during the entire healing period remains an urgent task for researchers. Fibrous materials based on biodegradable polymers and modifying ...
ASTROCYTES WERE ABLE TO BOTH SUPPRESS AND STIMULATE THE TRANSMISSION OF NERVE IMPULSES
2022-12-30 16:04
Scientists have shown that astrocytes — auxiliary cells of the nervous system — with various types of light stimulation either help to conduct nerve impulses, or prevent it. So, if proteins were artificially embedded in the astrocyte membrane — ion channels that pumped calcium into the cell when illuminated — the signal was inhibited. When astrocytes had proteins of a different nature — receptors — the spee...
A "PHOTON FACTORY" is being built in RUSSIA
2022-12-23 15:24
One of the most interesting projects that is being implemented today at the National Research Institute of MEPhI is the creation of a unique multifunctional kilojoule laser installation "ELF" (ELF – Experimental Laser-Physical installation; English: ELF - Experimental Laser Facility). This laser is also needed by world science, but it is also needed by the university, since large, preferably unique installa...
UN honours pioneering initiatives to restore ecosystems worldwide

These groundbreaking efforts were on Tuesday declared World Restoration Flagships at the UN Biodiversity Conference, COP15, in Montréal, Canada, and a virtual gala ceremony. Spanning 23 countries from Central America to East Asia, they are preserving a combined area bigger than Myanmar, France or Somalia, and seek to create nearly 15 million sustainable jobs. Countering a triple crisis They were selected un...

The researchers used materials derived from seaweed to improve synthetic vascular grafts.
A team of researchers from the University of Waterloo and the Oregon Health and Science University has developed a new approach to create synthetic vascular grafts for bypass surgery. The addition of natural materials derived from seaweed stimulates the growth of vascular cells and prevents the formation of blood clot...
UN Conference on Biodiversity: will it be possible to adopt a historic agreement
2022-12-02 17:15
The UN Conference on Biodiversity (COP-15) will be held in Montreal from December 7 to 19, 2022. Its participants plan to adopt a historic agreement defining urgent measures to prevent the rapid loss of many species of flora and fauna. Scientists warn that today our planet is experiencing the largest loss of all kinds of species since the extinction of the dinosaurs. However, this trend can be reversed.
