Implantable biocomputers

(via 3quarksdaily). From http://www.news.harvard.edu/gazette/2007/05.24/99-biocomputer.html:
"“Each human cell already has all of the tools required to build these biocomputers on its own,” says Harvard’s Yaakov “Kobi” Benenson, a Bauer Fellow in the Faculty of Arts and Sciences’ Center for Systems Biology. “All that must be provided is a genetic blueprint of the machine and our own biology will do the rest. Your cells will literally build these biocomputers for you.”

Evaluating Boolean logic equations inside cells, these molecular automata will detect anything from the presence of a mutated gene to the activity of genes within the cell. The biocomputers’ “input” is RNA, proteins and chemicals found in the cytoplasm; “output” molecules indicating the presence of the telltale signals are easily discernable with basic laboratory equipment."
There are also Indian names among the researchers:
"Benenson and Weiss worked in collaboration with undergraduate Keller Rinaudo, postdoctoral researcher Leonidas Bleris, and summer intern Rohan Maddamsetti, all at Harvard, and with Sairam Subramanian, a graduate student at Princeton. Their research is supported by Harvard University and a center grant from the National Institute of General Medical Sciences."
