Protein pathway to molecular nanotechnology

Jonathan Pugh asked about the protein pathway and how the recent breakthrough to apply variational analysis to allow for the calculation of protein folding a billion times simpler could advance molecular nanotechnology. One of Eric Drexler earliest papers discussed using proteins for molecular nanotechnology. A major milestone would be to make a version 2.0 of …

IBM to build Opteron-Cell hybrid supercomputer

IBM has won a bid to build a supercomputer called Roadrunner that will include not just conventional Opteron chips but also the Cell processor used in the Sony Playstation, CNET News.com has learned. This computer when completed should have sustainable petaflop level performance. Previous studies show that a modified cell chip could get 20 times …

Recent nanotechnology related news

Applying variational principles may allow streamlining of protein folding calculations from trillions of steps to hundreds. A variational principle is a principle in physics which is expressed in terms of the calculus of variations. The new application of the old physics method is faster because it allows them to spend less time calculating motions of …

Nanoscale oscillaters work together for stronger signal

Groups of nanoscale magnetic oscillators are known to synchronize their individual 10-nanowatt signals to achieve a signal strength equal to the square of the number of devices. Now scientists at the National Institute of Standards and Technology (NIST), Seagate Research Center (Pittsburgh, Pa.) and Hitachi Global Storage Technologies (San Jose, Calif.) have discovered how—the oscillators …

Understanding Gene Therapy boosting T-cells to beat cancer

The human immune system has about 2 trillion lymphocytes. About one trillion are t-cells T lymphocytes develop from precursor stem cells in fetal liver and bone marrow and differentiate into mature cell types during residence in the thymus. Mature T lymphocytes (antigen responding, response control, and response mediating cells) are present in thymus, spleen, lymph …
