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.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
