The pair of "tweezers" is made of dna and the opening and closing of the tweezers is the opening and closing of a circuit. These are truly useful tweezers.

Ian, >...story on researchers being able to manipulate Salmon DNA using it as a pair of tweezers to precisely place molecules on a substrate. Only problem I can see is that it would take all of eternity to make a single 4Mb chip which would have a useful value of $0.00 You have to start somewhere. ;-) Semiconductor memory (DRAM) started on an obsolete PMOS process, at 1Kb (actually 256 and 512 bits, but those chips never got to market). The 1Kb was the Intel 1103 and I designed a system around a bunch of them (showing my age). Anyway, IBM's latest research does push out that Buck Rogers stuff, hopefully another decade. Tony
