Scientists investigate the antiviral properties of the plant Graptopetalum paraguayense

The antiviral properties of the ornamental plant Graptopetalum paraguayense are being investigated by scientists from five scientific organisations. The plant is a drought-tolerant member of the Crassulaceae family that is grown as an ornamental houseplant in temperate climates. It is native to Mexico and is widespread in tropical and subtropical regions as an ornamental plant, but is used in Chinese medicine as a medicinal herb. It has a healing effect on people with conjunctivitis and herpes simplex, causing scientists to investigate its phytochemical composition and antimicrobial action. […]

New discovery at CERN with the participation of scientists from INRNE-BAS – first experimental observation of the odderon

First on the list of exciting results at CERN for 2021 is the experimental observation of odderon exchange in elastic proton-proton and proton-antiproton interactions. One of the lead scientists of this experiment is Dr. Georgi Antchev from the Institute for Nuclear Research and Nuclear Energy of BAS. He is the author of the data acquisition and processing systems and the coordinator of both the installation of these systems in the LHC tunnel and the testing and putting into operation of detectors. Odderons (a family of virtual, color-neutral states composed of an odd number of gluons) were predicted theoretically in 1973. The TOTEM, experiment, conducted at the LHC at CERN , studies the elastic scattering of protons which yields important information about the interaction and structure of these elementary particles.
