Hey what's goin' on I'm Amalia. I'm studying towards a MChem, chemistry degree at Smith College. My main research interests include neurochemistry, bioengineering, psychopharmacology, biopsychiatry, & synthetic biology.

According to the illegal chemist we talked to, not every Walter White wants to be more than a low-level highsmith.
6 Realities of Cooking Illegal Drugs (Not Seen on TV)

#6. Some People Get Into Manufacturing Drugs Because It Sounds Like a Fun Hobby
One day, a friend of mine mentioned in idle conversation that you could use nutmeg to get high. It’s true — I looked it up. Nutmeg contains a psychoactive chemical called myristicin, but what caught my eye was that it’s also about 2 percent safrole. It was a revelation. Safrole happens to be one of the main reagents for MDMA (Ecstasy). I thought to myself, “Oh. These aren’t manufactured out of thin air. These are from plants.”
I resolved to learn how to make it — mostly out of idle curiosity rather than criminal intent. I suspect a lot of nerdy kids get into this business because they love drugs and fall down the rabbit hole of studying how all these wacky chemicals affect their brains.

Human cortical neural stem cells
Cortical neurons are located in the cerebral cortex of the brain, a region responsible for memory, thought, language, and consciousness. Neural stem cells are “immature” cells committed to become neurons and helper cells of the brain. Neurons are the liaison between our brain and the world. When we eat a lemon, neurons connected to our taste buds tell the brain that it’s sour. Messages from the brain can also be sent elsewhere, as when neurons command muscles to contract while lifting a heavy object.

When companies develop antibacterial drugs, the Gram stain still draws an essential dividing line for judging the effectiveness of each type of compound. This is because the test reveals the makeup of the cell wall and so the penetrability of the wall by various drug types. Some antibacterials act against gram-positive bacteria and others against gram-negative, while those that act against both types are called wide-spectrum. A variation on the Gram technique gives a division between bacteria that are “acid-fast” or not.

Danish physician Hans Christian Joachim Gram was doing postdoctoral study at the University of Berlin in 1884 when he devised his differential staining of bacteria. In the first step, he dried a fluid smear on a glass slide over a burner flame and poured Gentian violet solution over it. After a water wash, he added potassium triiodide solution, which acted as a mordant to fix the dye if possible. Then he poured ethanol over the slide to wash away the dye. Bacteria cells that remained purple were positive, and those that did not retain the color were negative.

A few years later, pathologist Carl Weigert, director of the Senckenberg Foundation in Frankfurt, Germany, added a final step of staining with safranine. Today, bacteria are judged gram-negative if they retain the red color of safranine but not the first purple color of Gentian violet.

Gram-positive bacteria have thick cell walls of cross-linked polysaccharide that take Gentian violet well. Gram-negative bacteria have thin polysaccharide cell walls overlaid by lipid layers that resist staining by Gentian violet but that can be stained by safranine. In the acid-fast bacteria that cause tuberculosis and leprosy, the lipid layers are so waxy that only an etching stain like carbol fuschin can color them, but once colored, even ethanolic hydrogen chloride cannot decolorize them. Non-acid-fast bacteria take up a methylene blue secondary stain as a confirmation test.
