Understanding insulators with conducting edges

Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled ...

How does potassium enter cells?

For decades, it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers at Goethe University Frankfurt and University Groningen have ...

Study describes cellular factories in greater detail

Many important natural products such as antibiotics, immunosuppressants and cancer drugs are derived from microorganisms. These natural products are often small proteins or peptides generated in the cell by NRPS enzymes similar ...

Made-to-measure silicon building blocks

The broad spectrum of applications for silicones includes medical implants, cosmetics, hydraulic oils, sealants and corrosion protection—an important topic, in view of global corrosion damage to the tune of about US$ 3.3 ...

Physicists set limits on size of neutron stars

How large is a neutron star? Previous estimates varied from eight to 16 kilometres. Astrophysicists at the Goethe University Frankfurt and the FIAS have now succeeded in determining the size of neutron stars to within 1.5 ...

Black holes from an exacomputer

Even after the direct measurement of their gravitational waves, there are still mysteries surrounding black holes. What happens when two black holes merge, or when stars collide with a black hole? This has now been simulated ...

For how long will the USA remain the Nobel Prize leader?

Since first being awarded in 1901, most Nobel Prizes for science have gone to the U.S., the United Kingdom, Germany and France. An empirical study by Professor Claudius Gros from the Institute for Theoretical Physics at the ...
