Jason Palmer of BBC News brings us an AFM image from IBM Zurich which is simply wonderful:

Their measurement of a pentacene molecule using this carbon monoxide tip shows the bonds between the carbon atoms in five linked rings, and even suggests the bonds to the hydrogen atoms at the molecule’s periphery.

Breathtaking work by Leo Gross and team!  And sure to be of use on the pathways to molecular nanotechnology.  —Chris Peterson

Scientists have developed a new molecular sensor that can reveal the amount of zinc in cells, which could tell us more about a number of diseases, including type 2 diabetes.

Researchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.

The purpose of the OECD Series on the Safety of Manufactured Nanomaterials is to provide up-to-date information on the diverse activities at OECD related to human health and environmental safety. The latest publications are available for download .

In time for the 2009 Microscopy Conference in Graz, Austria, Carl Zeiss is presenting an integrated solution for correlative microscopy in materials analysis.

The National Science Foundation has awarded Clemson University researchers $2 million to study ways to mimic the suction mechanism used by butterflies and moths to feed so that the same method can be used in medical diagnostics.

Nanometrics Incorporated, a leading supplier of advanced process control metrology systems used primarily in the manufacturing and packaging of semiconductors, solar photovoltaics and high-brightness LEDs, today announced that Vincent Coates, company founder and vice-chairman of the board, has resigned from the Board of Directors.

With more than 20 years of research and teaching experience, Professor Holz will also develop NanoChemistry chapters of the NanoProfessor Program curriculum. The NanoProfessor Program aims to advance the field of nanoscience at the high school and university level, and address the need for a skilled workforce of nanotechnologists within various fields of science.

Was Silizium fuer die Entwickler von Computerchips, ist fuer Laserphysiker eine Substanz namens Lithiumniobat. Diese Stellung verdanken die durchsichtigen Kristalle vor allem einer schoenen Eigenschaft: Sie koennen die Farbe von Laserlicht veraendern. Dazu muessen sie allerdings ausreichend sauber sein. Und diese Reinigung war bislang ein schwieriges und teures Unterfangen. Forscher um den Bonner Physiker Professor Dr. Karsten Buse konnten freien Elektronen nun mit einem Besen aus Licht aus dem Kristall kehren.
