Do you have a rare blood group or are you concerned about contracting a disease such as HIV from a blood transfusion? The first ever European Blood Substitutes project (‘EuroBloodSubstitutes’) is designing molecules which will be able to replace the need for blood during transfusions in the future. Researchers are modifying the genes of the oxygen-carrying part of the blood (haemoglobin) and using cell factories to mass produce artificial molecules which will be able to oxygenate the body’s cells as efficiently, but without the possibility of contamination with disease.
Dr Ken Lowe (University of Nottingham, UK) who is coordinating the project says “We are using genomics to modify the haemoglobin as well as looking at ways to attach it to large molecules so that it stays in the body longer during transfusions. We are aiming to find the optimum molecules for oxygen-binding and transport as well as the best culture conditions for mass producing it for the future.” Dr Lowe will be reporting his results at the Society for Experimental Biology Annual Meeting in Barcelona on Tuesday 12th July [session E3.2].
This initiative is set to revolutionise blood transfusions which will become largely safe especially in emerging countries such as Eastern Europe and Africa where there are still relatively high risks of contamination.

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.
