“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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
