Silks are among the toughest materials known, stronger and less brittle, pound for pound, than steel. Now scientists at MIT have unraveled some of their deepest secrets in research that could lead the way to the creation of synthetic materials that duplicate, or even exceed, the extraordinary properties of natural silk.

The recent review of the past 10 years of the National Nanotechnology Initiative--as presented by the President's Council of Advisors on Science and Technology--suggested the rise of nanomanufacturing as the near future of nanotechnology. But the actual proposed funding reflects a cautious approach, even about nanotech in general.

Scientists at the Biodesign Institute at Arizona State have hit on a new, versatile method to significantly improve the detection of trace chemicals. The technique—electrochemical imaging microscopy—was able to detect and identify TNT particles weighing less than a billionth of gram on the ridges and canals of a fingerprint.

At 1.3 million cubic feet, the Goddard Space Flight Center’s High Bay Clean Room, where the components of the James Webb Space Telescope are now being assembled, circulates a staggering one million cubic feet of air per minutes, ensuring no more than 10,000 particles larger than 0.5 microns. Progress on the telescope can now be viewed by webcam.
