Here is a photo that will inspire you to wash your hands. A mother cultivated the bacteria present on her son’s hands. Almost the entire palm is covered with it.
No, it’s not art, but the only way a mother has found to get her son to wash his hands. Tasha Sturm, a biologist at Cabrillo College (California, USA), asked her 8-year-old son to put his hand in a petri dish after playing outside. She published the result on the platform imgur. A nice photo showing the shape of the hand. But the small forms that have hatched are a little less tasty than they appear: they are bacteria.
Not all bacteria are bad. As Tasha Sturm specifies in American Huffington Post, “Nothing in the box was terrible. Bacteria are everywhere. Our immune system develops from them. »Among the bacteria collected, some come from the soil, others from the digestive tract.
Only one organism raises the mystery: the one that developed outside the hand of the son of the biologist.
According to the researcher, the latter did not really learn anything from this little experience. “He thinks it’s the coolest thing on the planet,” she told the Huffington Post. It is therefore to bet that he will not wash his hands more often.
Similar results, although less aesthetic, were published in 2013 by a team from the University of Surrey (UK). This time, the researchers simply put their phone in a petri dish. When comparing the two pictures, some bacteria look very similar.
