Biosensor to battle cancer

A powerful new biosensor developed by European researchers will help identify cells in the immune system that actively suppress tumour growth, then put them to use. Enlisting the patient's own immune system would be like sending reinforcements for resistance fighters.

Physicists turn to radio dial for finer atomic matchmaking

Investigating mysterious data in ultracold gases of rubidium atoms, scientists at the Joint Quantum Institute of the National Institute of Standards and Technology (NIST) and the University of Maryland and their collaborators have found that properly tuned radio-frequency waves can influence how much the atoms attract or repel one another, opening up new ways to control their interactions.

Using self-assembly to make molecule-sized particles with patches of charge

Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.

New material could boost data storage, save energy

North Carolina State University engineers have created a new material that would allow a fingernail-size computer chip to store the equivalent of 20 high-definition DVDs or 250 million pages of text, far exceeding the storage capacities of today's computer memory systems.

0.2 second test for explosive liquids

New research explains how a new form of spectroscopy, a scientific method that uses electromagnetic radiation to identify materials, and a novel nanoelectronic device to detect signals, can identify explosive liquids, or liquid components for the fabrication of explosives, in usual plastic bottles almost instantly.

Die meisten Deutschen haben keine Vorstellung von Nanotechnologie

Die Nanotechnologie weckt diffuse Hoffnungen. Ihr Nutzen wird vom ueberwiegenden Teil der Deutschen hoeher eingeschaetzt als die moeglichen Risiken. Gleichzeitig hat nur ein geringer Teil der Bevoelkerung eine klare Vorstellung davon, was unter dem Begriff ueberhaupt zu verstehen ist.
