Dr Lori Passmore is head of the Mechanisms of Macromolecular Machines group in the Structural Studies Division at the MRC Laboratory of Molecular Biology (LMB). She showed Isabel Baker around her shiny new office where she approaches biological questions using structural biology methods.
These coasters were made by a friend of mine who does glass fusing. She’s put some actual electron microscopy (EM) grids, which we use to image proteins, inside the glass. Each grid is 3mm in diameter, made of a disc of metal such as copper or gold, often with a layer of carbon on top. To use these grids in the lab, we pipette a few microlitres of protein in solution on top and remove the excess solution, leaving a thin layer containing the protein. For cryo-EM – where we freeze the samples at liquid nitrogen temperature to preserve them in the vacuum of the microscope – the carbon has holes in it. When you freeze the grid, the protein molecules are trapped in ice suspended across the holes. We then image the protein, in the suspension of ice across the grid. Read more
Think James Lovelock, and most people think about Gaia theory, his idea that the Earth is a self-regulating system that keeps the conditions for life in a delicate equilibrium. But for 20 years Lovelock was a scientist at the MRC National Institute for Medical Research, studying a wide range of areas from preventing burns to freezing tissues. Katherine Nightingale went to a Science Museum exhibition about his life and work to find out more from its curator Alex Johnson.

Much is made of James Lovelock’s decades as an independent scientist and inventor in a shed at the bottom of his garden. His thirst for scientific freedom and invention is well known ― even his adolescent short stories feature protagonists who just want to be left alone to pursue their own ideas.
Funny then, that Lovelock himself says that some of his most creative work was done while part of a large institution, the MRC National Institute for Medical Research, between 1941 and 1961.
He has been known to refer to his time at the NIMR as an extended apprenticeship, working in various research divisions across the institute, and being encouraged to solve his own problems and create his own equipment. Read more
