Molecular tools make the cut

Researchers in Japan have developed a pair of molecular-scale scissors that open and close in response to light. The tiny scissors are the first example of a molecular machine capable of mechanically manipulating molecules by using light, the scientists say. The scissors measure three nanometers in length, small enough to deliver drugs into cells or manipulate genes and other biological molecules. The research will be presented in March at the American Chemical Society meeting in Chicago.

   If there were a pill that would cut your risk of breast cancer in half, would you take it? What if you were told your risk of breast cancer was already below average? In a newly published survey, women who were told their risk of breast cancer was above average were more likely to endorse taking the hypothetical pill than women who were told their risk was below average.

   Any machinist will tell you that a little grease goes a long way toward making a tool work better. And that may soon hold true for plastic electronics as well. Carnegie Mellon University chemists have found that grease can make some innovative plastics vastly better electrical conductors. This discovery, published June 25 in Advanced Materials, outlines a process that could become widely adopted to produce the next generation of tiny transistor switches.

6. Researchers identify cells that make relapse inevitable in acute lymphoblastic leukemia
   11-09-2006 · EurekAlert!
   Scientists in Australia have discovered that in acute lymphoblastic leukemia (ALL) there are "good" and "evil" clones of the same type of ALL cell. The "evil" cells are clones that have a pre-existing resistance to drugs used for treating ALL, and their presence in a patient means that person will inevitably relapse after chemotherapy, according to research presented at the 18th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics.

10. Breaking the nanometer barrier in X-ray microscopy
    11-09-2006 · EurekAlert!
    Argonne National Laboratory scientists in collaboration with Xradia have created a new X-ray microscope technique capable of observing molecular-scale features, measuring less than a nanometer in height. Combining x-ray reflection together with high resolution x-ray microscopy, scientists can now study interactions at the nanometer-scale which often can exhibit different properties. Improving our understanding of interactions at the nanoscale holds promise to help us cure the sick, protect our environment and make us more secure.
