When the SARS-CoV-2 virus mutates, this initially only means that there is a change in its genetic blueprint. The mutation may lead, for example, to an amino acid being exchanged at a particular site in a viral protein. In order to quickly assess the effect of this change, a three-dimensional image of the viral protein is extremely helpfu...
Last modified on Wed 12 May 2021 23.19 EDT Andrew Thomson, who has died aged 80 after a stroke, played a crucial role early in his career in the discovery of a widely used anti-cancer drug, cisplatin, before going on to do pioneering work in the field of spectroscopy, enhancing our understanding of the functioning of substances vital to life, such as haemoglobin. As an Oxford research chemist with a background in platinum chemistry, in 1967 Andrew was invited to Michigan State University by a group of biophysicists who had found that passing an electric current, using platinum electrodes, thr...
E-Mail Researchers have genetically engineered a probiotic yeast to produce beta-carotene in the guts of laboratory mice. The advance demonstrates the utility of work the researchers have done to detail how a suite of genetic engineering tools can be used to modify the yeast. "There are clear advantages to being able to engineer probiotics so that they produce the desired molecules right where they are needed," says Nathan Crook, corresponding author of the study and an assistant professor of chemical and biomolecular engineering at North Carolina State University. "You're not just deliveri...
