Omega 3 fatty acid supplements in pregnancy | The ageing process and autophagy | Dark Winter: a book about biological attacks, accidents, and COVID-19

Fish oil supplements—aka omega 3 fatty acids—are taken by some women during pregnancy. What are the benefits, and who gets them?

Research into ageing has revealed a number of processes controlling its rate. Autophagy helps cells do a clean up. Researchers are wondering if it could be manipulated.

Is it possible to say whether a pandemic is a natural spillover from an animal, or an accidental release from a lab? In her new book, Dark Winter, Professor Raina MacIntyre warns that scientists may not be the people to identify the source of pandemics—rather that Intelligence and law enforcement services could have a better toolkit.
