My article for the Telegraph:
In 1934, in their spare time, two American biologists, Pearl Kendrick and Grace Eldering, developed a vaccine for whooping cough, then the biggest killer of children in the United States. Within four years their vaccine was being used throughout Michigan and within six it was being used nationwide. Whooping cough rapidly retreated.
Since then there have been spectacular advances in biology, including the identification of the genetic material, the ability to read its code, an understanding of the structure of viruses and the proteins from which they are made, plus knowledge of how immunity works. So why are we facing a wait of at least a year, maybe much more, for a vaccine for coronavirus? It has been one of the shocks of recent weeks to realise how little progress vaccine development has made. It’s still a bit of an art.
My article for The Telegraph:
In the 19th century Ignaz Semmelweis was vilified and ostracised when he tried to make doctors wash their hands after doing autopsies on women who had died from childbirth fever before going straight upstairs to deliver more babies. We have come a long way since then in public health, but we can go much further still.
The fruit of a narrow-leaved campion, buried in permafrost by a ground squirrel 32,000 years ago on the banks of the Kolyma river in Siberia, has been coaxed into growing into a new plant, which then successfully set seed itself in a Moscow laboratory. Although this plant species was not extinct, inch by inch scientists seem to be closing in on the outrageous goal of bringing a species back from the dead. I don't expect to live to see a herd of resurrected mammoths roaming the Siberian steppe, but I think my grandchildren just might.
The mammoth is the best candidate for resurrection mainly because flash-frozen ones with well-preserved tissues are regularly found in the Siberian permafrost. Occasionally these have been fresh enough to tempt scientists to cook and eat them, usually with disappointing results. Just last week a Chinese paleontologist in Canada, Xing Lida, filmed himself frying and eating what he said was a small mammoth steak. Cells from such carcasses have been recovered, encouraging a rivalry between Japanese and Russian scientists to be the first to revive one of these huge, elephant-like mammals by cloning. Four years ago the mammoth genome was sequenced, so we at least now know the genetic recipe.
The news of the resurrected flower does, apparently, remove one obstacle. After 32,000 years the plant's DNA had not been so damaged by natural radioactivity in the soil as to make it unviable, which is a surprise. Mammoth carcasses are often much younger - the youngest, on Wrangel Island, being about 4,700 years old, contemporary with the Pharoahs. So the DNA should be in even better shape.
