Nano particules may trigger cancer

Lab experiments find that nickel particles with diameters billionths of a meter wide can trigger a cellular pathway that promotes cancer growth.  All the excitement about nanotechnology comes down to this: Structures of materials at the scale of billionths of a meter take on unusual properties. Technologists often focus on the happier among these newfound capabilities, but new research by an interdisciplinary team of scientists at Brown University finds that nanoparticles of nickel activate a cellular pathway that contributes to cancer in human lung cells.

  Left you see it, right you don’t see

When human lung epithelial cells are exposed to equivalent doses of nano-sized (left) or micro-sized (right) metallic nickel particles, activated HIF-1 alpha pathways (stained green) appear mostly with the nanoparticles.

Fujitsu Siemens focuses on the future nanocomputer


Rugged nano computer for industrial applications

 

A particularly compact design and the Atom processors of the power-optimized E6xx series from Intel are the key features of the new Simatic IPC227D Nanobox PCs and the Simatic HMI IPC277D, launched in may this year. These computers are  Nanopanel PCs from the Siemens Industry Automation Division. The devices belong to a new product line of particularly compact and energy-saving industrial PCs in the nano-format. A new step towards the coming first nanocomputer.
Siemens is one of the leading manufacturers of industrial computers in Europe. The company’s plant in Karlsruhe develops and manufactures all of the computer parts on its own — from the motherboard to the housing. These computers are used in industrial facilities, for building management, and in transportation systems.
