If it moves, it's probably alive: Searching for life on other planets
(arstechnica.com)
The search for extraterrestrial life has always been a key motivator of space exploration. But if we were to search Mars, Titan, or the subsurface oceans of Europa or Enceladus, it seems like all we can reasonably hope to find is extremophile microbes. And microbes, just a few microns long and wide, will be difficult to identify if we’re relying on robots working with limited human supervision and without all the fancy life-detecting gear we have here on Earth.

The brain microbiome: could understanding it help prevent dementia?

Long thought to be sterile, our brains are now believed to harbour all sorts of micro-organisms, from bacteria to fungi. How big a part do they play in Alzheimer’s and similar diseases?

Bacterial World
(ox.ac.uk)
Bacteria survive, thrive, fight and die by the trillion every moment. They swim using nanoscopic motors, and battle with spears. They sense, communicate, remember. And as scientists discover more about these tiny organisms, it is becoming clear that bacteria wield huge influence over us, shaping Earth’s past, our present and the future for us all. We have only recently realised how much our lives are inextricably linked with the lives of bacteria. We really are living in a bacterial world.

Clinical microbiologist explains why you should never kiss a baby
(medicalxpress.com)
There is a cognitive bias called "the curse of knowledge" (sometimes also called "the curse of expertise"). It happens when you incorrectly assume that everyone knows as much as you do on a given topic. As a clinical microbiologist, I assumed everyone knew that it was a terrible idea to kiss a newborn baby anywhere on its head.
