Nanoscientists have transformed a molecule of chlorophyll-a from spinach into a complex biological switch that has possible future applications for green energy, technology and medicine.

In Salmonella, structural changes to the molecular infection apparatus also signal an end to its further assembly. The mechanistic details of this sophisticated feedback system, which takes place at molecular level, have now been published in Nature. Better understanding of how this pathogen’s needle-like secretion injectisome is formed will offer new approaches to preventing the infection process in future. The results obtained by the team of Thomas Marlovits, joint IMP-IMBA Group Leader and head of the new “Spot of Excellence” at the Campus Vienna Biocenter, have now been explained by using modern techniques of three-dimensional cryo electron microscopy.

Nanotechnology may one day help physicians detect the very earliest stages of serious diseases like cancer, a new study suggests. It would do so by improving the quality of images produced by one of the most common diagnostic tools used in doctors' offices—the ultrasound machine.

Regulatory oversight of nanotechnology is urgently needed and the Environmental Protection Agency (EPA) should act now, reports a new study released today. In EPA and Nanotechnology: Oversight for the 21st Century, former EPA assistant administrator for policy, planning and evaluation, J. Clarence (Terry) Davies, provides a roadmap for a new EPA to better handle the challenges of nanotechnology. New nanomaterials and nanotechnology products are entering the market each week, and an adequate oversight system is necessary to identify and minimize any adverse effects of nano materials and products on health or the environment. Davies’ report sets out an agenda for creating an effective oversight system as nanotechnology advances—the technology that some have hailed as “the next industrial revolution.”

Nanoscience Instruments announces the release of the Nanosurf® Nanite automated Atomic Force Microscope (AFM). Innovators and makers of the most compact and easy-to-use AFMs on the market, Swiss-based Nanosurf AG, have applied their inventive designs to the challenge of automated multiple measurements—the result, a new easy to use AFM that provides true walk-away time. The Nanite is designed for use in a variety of nanoscale surface analysis applications ranging from coatings, polymers, fabrics and fibres—to semiconductors, wafers, optical and holographic surfaces, and data storage.
