Alter-ego of @DrStuartFraser1 obsessed with the etymological origins of scientific terms

[Dr Stuart Fraser @DrStuartFraser1]

Incredibly proud of my last PhD student from medical sciences at USYD @chancolonne. Not only was her abstract for the American Society of Hematology meeting selected for an oral presentation but it just was just selected for the ASH-HSANZ abstract achievement award!

Very proud of this work where we introduce the proof of concept for intracellular magnetic cell sorting where we use plasma-treated magnetic particles and histochemical dyes to separate populations according to intracellular traits.

The Greek alphabet has two letters ‘O’. A mega big one called Omega. And micro small one called Omicron. They were probably pronounced differently in Ancient Greek.

Our ANAT3888 students were spectacular with the cardiac etymology session today. The group google doc worked brilliantly. Thanks to @Biologist_Bobby @NataLazzza and @anh_sydney for a great time. And the words cordial and courage come from the Latin “cor” for heart

[Etumon-Au @StuartF11392758]

To offer a brief scientific distraction during these tough times I’m offering to find the origins of your favourite scientific words and terminology. Send along words and I’ll find the origins. Starting with virus; latin for slimy poison

@DrKristjanT It can be adapted easily to etymology in anatomy, physiology, chemistry, physics

[Etumon-Au @StuartF11392758]

@DrKristjanT But the main task was students presenting to each other the origins of the words for cells, tissues, organs, genes really quickly using their phones and a white board wall

[Etumon-Au @StuartF11392758]

@DrKristjanT It was great fun and happy to share our experience with anyone interested. That day was focused on words in development and at Sarah’s great suggestion we finished with pioneering female developmental biologists.

M is for morphometry-the measurement (metron) of shape or form (morph). Form morphs into morf. Morpheus was the Greek god who shaped dreams. And the drug linked to him (add inus at the end to mean ‘pertains to’) and you get morphine.

[Etumon-Au @StuartF11392758]

L is for laryngology, the study of the larynx, Greek origin meaning upper windpipe. Also for laryngoscopy-seeing the larynx; laryngography-imaging the larynx;and laryngotomy, slicing or cutting the larynx

[Etumon-Au @StuartF11392758]

The word “oil” comes from the Middle English/old French word “oile” or “oyl”. These in turn came from the Latin word “oleum” which means olive oil. Petroleum is oil from rocks.

[Etumon-Au @StuartF11392758]

From my histology teaching of bone development. The manubrium-part of the sternum-means handle or hilt, like something held in the hand (manus in Latin-as In manual work). It looks like a swords hilt

[Etumon-Au @StuartF11392758]

K is for karyotype. Karyo is from Greek karuon meaning kernel and refers to the nucleus. Type is also from the Greek tupos which become latinised to typus meaning impression or figure. So karyotype is the impression of the nucleus, or the imaging of chromosomes

Got stuck on J. But J is for japanology-a subject I would love to devote time to

[Etumon-Au @StuartF11392758]

I is for Immunology study of the im/mune -or "not mune"-system. -Mune refers to a tax and comes from the same origin as municipal. "Immune" is exempt from a tax-in this case the tax of dying from an infectious disease.

@DrStuartFraser1 practicing on iMovie with the beauty of Alizarin Red-watch the separation of the dye at high pH

[Etumon-Au @StuartF11392758]

H is also for Helminthology-the study of worms (helmins in greek) such as the wonderful planaria we looked at this week. Here's the head of one, stained with an antibody against neural processes. The eye spots are the darker bean shapes.

[Etumon-Au @StuartF11392758]

Check out my new Youtube channel Histo2dye4 to see the beauty of histological dyes. https://t.co/spHMgP1X74

[Etumon-Au @StuartF11392758]

H is for Histology. The study of tissues (histos-in greek. Mix it with chemistry and you have histochemistry-the use of chemical dyes and probes to detect differences in tissue composition.
