PopSci reports that scientists have managed to make a drop of oil successfully maneuver a maze using alkaline and acidic solutions.
The researchers devised the experiment as part of a project to develop new anti-cancer drugs. They were looking to solve a problem where drugs effective in the lab fail to cure the disease, due to the medicine's inability to navigate the maze of blood vessels leading to a tumor. With this discovery, the scientists may have found a way to encourage anti-cancer medication to migrate to the right spot, even after getting lost in the body's intricate circulatory system.
Medications that directly microtarget the source of the problem and don't waste time and energy spreading throughout the body. Imagine what will happen when somebody finds a way to do this with narcotics. You'll never have to leave the house again.
