Mitochondria, ageing and separate sexes This seminar was given at the kind invitation of Prof. Dr. Mariusz Nowacki. I received excellent questions and comments from members of an expert audience. There seemed to be agreement on my view of the experiment we should do next. It was a pleasure to meet Mariusz’s lab members, including… Continue reading 30 May | Institute of Cell Biology, University of Bern

Energy, ageing, fidelity and sex. Oocyte mitochondrial DNA as a protected genetic template A lively audience packed into a small lecture theatre in the beautiful UNAM Campus Juriquilla. Good questions introduced many ideas new to me. I thank Dr Alfredo Varela, the newly-appointed director of the Institute of Neurobiology, for generous hospitality. This included an… Continue reading 4 May | Instituto de Neurobiología UNAM

Regulation of photosynthesis. Control of chloroplast DNA transcription and membrane protein phosphorylation I felt at home in the research laboratory of Dr. Carlos Gómez of the Department of Biochemistry. I saw a French Press, spectrophotometers and fluorimeters, SDS-PAGE, sucrose gradient centrifugation, and cultures of fascinating cyanobacteria. I learned that Spirulina, once a Mexican speciality and… Continue reading 3 May | Departamento de Bioquímica, CINVESTAV

A formidably well-informed audience volunteered numerous good questions during and after my presentation Energy, ageing, fidelity and sex. Oocyte mitochondrial DNA as a protected genetic template. I sensed a degree of polite scepticism. Good. There is no point in explaining things to people who already agree. Such an appreciative and critical audience is definitely good… Continue reading 29 April | Instituto de Fisiología Celular, Universidad Nacional Autónoma de México

Why chloroplasts and mitochondria retain their own genomes and genetic systems I felt I had to truncate the advertised title, that of my 2015 PNAS paper. I feared that the original title would put too much text on the first slide, tending to sap the will to live amongst members of a general audience. I… Continue reading 28 April | Fisiología Biofísica y Neurociencias, CINVESTAV

A redox switch hypothesis for the evolutionary origin of oxygenic photosynthesis It could be quite wrong. If it is, this great lab may well be the first to find out. I told them this at the outset, and asked them to let me be the first to know. This caused amusement, while I was actually… Continue reading 27 April | Instituto de Ecología, Universidad Nacional Autónoma de México
