Theoretical physicists of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz are working on a theory that goes beyond the Standard Model of particle physics and can answer questions where the Standard Model has to pass - for example, with respect to the hierarchies of the masses of elementary particles or the existence of dark matter. The central element of the theory is an extra dimension in spacetime. Until now, scientists have faced the problem that the predictions of their theory could not be tested experimentally. They have now overcome this problem in a publication in the current issue of the

Joint press release of Johannes Gutenberg University Mainz and Paul Scherrer Institute PSI
In experiments at the Paul Scherrer Institute PSI, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than ever before. With the aid of the new value, fundamental physical theories can be tested and natural constants can be determined even more precisely. For their measurements, the researchers needed muons – these particles are similar to electrons but are around 200 times heavier. PSI is the only research site in the world where enough so-called low-energy muons are produced for such experiments. Their results were published in the journal

The technology used in COVID-19 vaccines may also be used to prevent other viral infections and to treat cancer and multiple sclerosis. Advertisement
The same messenger RNA (mRNA) technology used in the Moderna and Pfizer/BioNTech coronavirus vaccines, which are around 95% effective at preventing symptomatic COVID-19, could potentially be used to prevent or treat a wide variety of other diseases.
Moderna recently announced that it has started new programs to design mRNA vaccines for HIV, seasonal influenza and Nipah virus, adding to the company’s development portfolio for several other viral diseases and cancer.
