Ghost stories and Christmas go together like Salmonella and mayonnaise. So I've written my contribution to this long tradition over at MicrobiologyBytes:
By 3 o'clock the light had almost gone from the room and the candles were already lit. Antonie van Leeuwenhoek had been working all d o'clock the light had almost gone from the room and the candles were already lit. Antonie van Leeuwenhoek had been working all day in his draper's shop, pausing only briefly to return to his house for a short lunch with his wife Barbara. His eyes were tired and the threads on the linens became finer year by year as the weaving machinery improved. But without a close examination of each sample of cloth it was impossible to know what was a fair price to pay and how much his customers would be willing to part with for it. He rubbed the square of linen between his finger and thumb, trying to gauge the evenness of each thread, to predict how hardwearing this sample would be. In fatigue and frustration he cast the cloth aside onto his work bench.
