With support from the National Science Foundation, she and her team are using high speed cameras to help them study how dragonflies pull off complicated aerial feats that include...

Novel antimalarial drug development

submitted by: COMED2010
The main objective of the AntiMal Integrated Project is to generate novel antimalarial drugs with potential for use in humans, specifically to progress candidate molecules to the “first time into humans” stage of drug development. To achieve this goal, leading groups of malaria researchers from Europe and Africa with expertise in malaria biology, chemotherapy and drug development have come together to exploit new scientific and political opportunities to secure the development of a...
