Randall Parker of FuturePundit has more on new research aimed at developing medical nanomachines - to deal with arterial plaque in this case. He makes a good point: "This is another example of development of a treatment that falls within the typology of 7 Strategies for Engineered Negligible Senescence (SENS) to halting and rejuvenate bodies by the removal of accumulated extracellular junk. ... Widespread acceptance of SENS for rejuvenation is not necessary for the development of many SENS treatments. My guess is that for at least the next decade most treatments which will accomplish objectives which support SENS will be justified under the old paradigm of development of treatments against specific diseases. Efforts such as this one develop tools that will be useful for rejuvenation. So we are making progress toward the goal of engineered negligible senescence or perpetual youth."
