A rack-and-pinion device at the molecular scale

Christian Joachim, has lead a research team that has made a molecular rack-and-pinion device for which an STM tip drives a single pinion molecule at low temperature. The pinion is a 1.8-nm-diameter molecule functioning as a six-toothed wheel interlocked at the edge of a self-assembled molecular island acting as a rack. They monitor the rotation …

Space articles roundup

An article discussing evidence for and against ice on the moon I agree that we should continue with sending the robotic probes necessary to be absolutely certain about what ice is or is not there and what can be used. An article that discusses getting energy from space or deflecting sunlight to counter global warming. …

Futurehype is an interesting book

Futurehype by Bob Seidensticker is an interesting book and there are excerpts at his website He does point out some problems that make technology and societal predictions hard. However, I believe it is possible to be quite accurate. I agree with him that understanding the past and the past of technology matters.I agree with him …

Superscale pyrosequencer for 2009/2010 full genome sequencing

Mostafa Ronaghi, one of the inventors of this sequencing chemistry, group at Stanford is working on an inexpensive superscaler pyrosequencer. It would use $10 CMOS imaging instead of $100,000 CCDs. The objective is to run 400 million sequencing reactions in parallel that can produce between 60 and 100 gigabases of data per run with 200-base …

World Future Society predictions are wrong

The World Future Society makes forecasts which show that the forecasters do not seem to really understand some of the technology that they are forecasting. Forecast #2: The era of the Cyborg is at hand. Researchers in Israel have fashioned a “bio-computer” using the DNA of living cells instead of silicon chips. This development may …

Leading DNA sequencing scientist predicts 2007 as year of personal genomics

George Church predicts 2007 as the year of personal genomics The price to sequence the 1% of the genome that differentiates people will drop to a street price of $3000 in 2007. Momentum is thus building for millions of people to volunteer to have their genome data correlated with their physical-traits to benefit the billions …

More from the Steve Chen Supercomputer Interview

The Chinese government supports university research and gives them money to pay for the use of the service [supercomputer grid]. That is better than to spend money on buying thousands of separate smaller systems and none of them can do significant work. China only has two supercomputer centers now. Steve Chen is recommending and apparently …

Speculation: Room temperature superconductors : milestone to complete master of energy and matter

By getting superconducting theory right (or making enough progress from theory and better experiment), we could guide material design of room temperature superconductors, higher current density material, better electronics, better power grid, possible magnetically ground launched space craft. Room-temperature superconductors would be an important milestone on the path to complete mastery (within the actual limits …
