Pathology4Kids
"The simplest way to inspire the next generation of pathologists, brought to you by the real professionals." Pathologists and scientists turned what they see under the microscope into bright pictures and a few plain words a child could enjoy, and shared them under the hashtag #Pathology4Kids.
The idea was small on purpose. A pathologist spends the day looking at cells; a child has never heard the word. One picture with an arrow and a name ("these pink dots are eosinophils") closes that distance in a few seconds.
One activity on the old site was called "draw with your microscope": a cartoon picture made under a microscope and scanned at 20× magnification, so children could zoom into it the way a pathologist zooms into tissue.
Who made it
Contributors were pathologists and scientists in the UK and the USA, sharing on Twitter and LinkedIn. The old page pointed to the hashtag instead of listing them, so we won't guess names here.
Meet them · in the spirit of #Pathology4Kids
Meet four blood cells
A drop of blood, stained and seen under a microscope, looks like a crowd. Here are four of the regulars. An AI drew them for this site, simplified on purpose: they are not photographs of real cells.
Red blood cell
A squashed disc with no nucleus, thinner in the middle. It is the most common cell in blood, and it carries oxygen around your body.
Neutrophil
Its nucleus is split into lobes, like a short string of beads. It is one of the first defenders when an infection starts.
Eosinophil
Two round lobes like a pair of glasses, and big orange-pink dots. It responds to parasites and to allergies.
Lymphocyte
Small, with one big, dark, round nucleus that almost fills it. It is part of the body's immune defences.
What the words say comes from: Loyola University Medical Education Network, “HistoLab Part 5: Blood and Capillaries” (J. A. McNulty; web page, updated 1996); Y. Clermont, M. Lalli and Z.
