Researchers at the National Institute of Standards and Technology (www.nist.gov) have developed a new method to produce uniform, self-assembled nanocells for drug therapies, such as chemotherapy, in which dosage depends critically on the size of the nanocells. The new method uses micrometer-size channels etched into a device to produce self-assembled liposomes—a type of artificial nanocell—of specific sizes from 100 to 240 nm. A stream of lipids dissolved in alcohol is directed at an intersection of two channels while a water-based liquid containing medicines or other substances is sent toward the lipid stream from two opposing directions. Self-assembled nanocells are formed when the lipids surround the water rather than mixing with it.
Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
