We are very grateful for the research support we receive and are keen to share our science, activities and experiences with the public. We hope you find them interesting!


The New Scientist Live! is a science public engagement event, which took place in Excel during September 2018 and showcases the ongoing research innovation in the UK. It attracts people of all ages and from various backgrounds, who are either interested in science or just a bit curious. The participants of this event come from a diverse range of fields, including physics, chemistry, biology, and engineering and they have the opportunity to inspire new generations, address concerns and most importantly inform their peers!
Stelios was at the SBSRC Nottingham stand, where a variety of activities took place. Attractions included a computer model of a biochemical pathway, an anaerobic cabinet, microscope drawing of some bacteria and some examples of potential products as well as a VR for a hands on experience in the lab.

International Women's Day

It’s International Women’s Day! One outstanding female scientist is Tu Youyou, a Chinese chemist who won a Nobel Prize in 2015 for her discovery of artemisinin, which is now one of the most important drugs in our arsenal against malaria.

Artemisinin was discovered by Tu Youyou’s group against the backdrop of the proxy war against the USA in Vietnam, where malaria was an enormous problem for both sides since it incapacitated a significant proportion of troops [1]. To find a solution, the Chinese turned to their well-documented heritage of traditional medicines. They methodically tested different herbs that were used against malaria and found that extracts from Artemisia annua displayed exceptional antimalarial activity. [2]

The active component was isolated and in 1975 its chemical structure was elucidated. Later, chemists developed similar drugs, some of which were even more potent, by making small alterations to the structure of artemisinin.

One problem shared by many plant-derived drugs is variability in the content of the active compound. It is possible to breed varieties that produce larger

amounts of artemisinin, but changes in environmental factors such as temperature, nutrient availability, time of harvest etc. can still cause variations in artemisinin levels [3]. To avoid gambling the supply of artemisinin on the vagaries of Nature, several other approaches for the production of artemisinin-type drugs have been devised.

One approach is “total synthesis” i.e. production of the drug from scratch using the methods of organic chemistry. However, since artemisinin is quite a complex molecule it is difficult to design a process which is efficient enough to compete with simply growing the plant. [4]

There’s an alternative approach to the production of artemisinin which uses biocatalysis - the same type of thing we do in the O’Reilly Group. This route obviates the need to grow the plant at all. The genes responsible for production of artemisinin are instead inserted into baker’s yeast, which is easily grown on a large scale to produce the drug at very low cost. [5]
