1948 Discovery of warfarin

  • Warfarin is an anticoagulant and pesticide. It was initially used as a pesticide but was later found to be effective and relatively safe for preventing thrombosis and embolism in many disorders and is currently the most widely used anticoagulant worldwide. It was discovered by Karl Paul Link and chemists at the University of Wisconsin–Madison.[37]

To fellow Medical Technologists, next time you run a coagulation test remember this. Wierd. But true!!

POST-IT anywhere!

 I love Post-it notes. These great little self-stick papers are useful for forgetful people like me.

The story? No one actually burned a brow overnight to invent Post-it notes. Like many other things, it was invented by accident. A guy named Spencer Silver was working in 3M Research laboratory in 1970 trying  to make a strong adhesive. What turned out was a weak adhesive that could easily be lifted off. Silver however did not discard the failed invention.

Four years later, Silver’s colleague Arthur Fry in church choir was using markers in his hymnal. It was such an inconvenience for they kept falling out of the book. Remembering Silver’s weak  adhesive, he used some and it was…bingo!

In 1980, 3M Research began distributing Post-it notes nationwide. Today, there is no denying that Post-it notes invention was not really a failure.
