Scientists use nanosensors for first time to measure cancer biomarkers in blood.  From Eurekalert: New Haven, Conn.—A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings, which appear December 13 in the advanced online publication of Nature Nanotechnology, could dramatically simplify the… Continue reading Scientists use nanosensors for first time to measure cancer biomarkers in blood

Researchers show how proteins slide along DNA to carry out vital biological processes. For decades, scientists have known that proteins searching for genetic sequences are able to locate them at rates much faster than expected. They found that rather than moving around the entire three-dimensional space inside a cell, they moved in one-dimension, along DNA… Continue reading Researchers show how proteins slide along DNA to carry out vital biological processes

Technology Review: Blogs: arXiv blog: Self-Propelling Bacteria Harnessed to Turn Gears. No, it’s not harnessing the flagellar rotory motor to turn nanogears, it’s harnessing the entire beast, statistically, to turn microgears. Still interesting.

YouTube – IBM DNA Transistor. It isn’t really a transistor, it’s a gadget for sequencing DNA through a nanopore. But it’s getting close to the way one expects nanotech to read a molecule, as it it were a magnetic tape or the like. Now if they could only come up with a way to write… Continue reading IBM DNA "Transistor"
