“We’ve shown that it’s possible to move away from the traditional, highly labour-intensive way of describing a new species. Developments in molecular biology have made it possible to determine the genetic code for selected parts of DNA both quickly and cheaply.”
Swedish species – and the two researchers have opened the door to new methods for determining species.
the link between the name and the species, and prevents the same name from being used for different species. An international committee keeps track of all valid species names.“The description of the species is an extremely important part of the naming process. A species without a name just doesn’t ‘exist’. Without valid names for species, our perception of biological diversity is skewed.”
However, this is a time-consuming process that in many cases involves expensive special techniques and specialist expertise. As a result, many new species are not described, but instead remain unprocessed.Ribbon worms are an example of creatures that are traditionally described using anatomical characteristics, in other words how their internal organs such as intestines, blood vessels and brain are organised and what they look like. The recently published species description means that the two Gothenburg researchers are paving the way for more new species to be registered by linking
a species-specific DNA code to a name.
Malin Strand and Per Sundberg from the University of Gothenburg both have links with the Swedish Species Information Centre.The article A DNA-based description of a new nemertean (phylum Nemertea) species has been published in the scientific journal Marine Biology Research.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
