Quantum teleportation succeeded through a 16km long free space channel

In previous experiments the photons were confined to fiber channels a few hundred meters long to ensure their state remained unchanged, but in the new experiments pairs of photons were entangled and then the higher-energy photon of the pair was sent through a free space channel 16 km long.

New technique turns proteins into glass: Could lead to new ways to deliver medication

Duke University researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology.

Study suggests that silver nanoparticles mitigate the cell damage caused by ethanol

The results of the study show that these clusters of small numbers of silver atoms catalyze ethanol oxidation at similar concentrations to those found in the blood of alcoholics and at values of membrane potential and pH that are compatible with those exhibited by mammalian cells.

Testing predictions in electrochemical nanosystems - from theoretical insights to the lab bench

Physicists at the Technische Universitaet Muenchen (TUM) are gearing up for experimental tests of findings they arrived at through theoretical considerations: that electrochemical reactions take place more rapidly on isolated, nanometer-scale electrodes than on their familiar macroscopic counterparts, and that this surprising behavior is caused by thermal noise.

Gas sensor chip paves the way to autonomous electronic nose

Imec and Holst Centre have developed very sensitive integrated sensing elements for gas detection. The polymer-coated microbridges in high-density arrays can detect ppm-level concentrations of vapors using on-chip integrated read-out techniques.

A new approach to finding and removing defects in graphene

Researchers pinpointed noncarbon atoms that create defects when graphene is produced through a technique called graphene-oxide reduction. The researchers also propose how to make that technique more efficient by precisely applying hydrogen - rather than heat - to remove the impurities.

Novel way of revealing 3-D internal cell structure

Three-dimensional imaging is dramatically expanding the ability of researchers to examine biological specimens, enabling a peek into their internal structures. And recent advances in X-ray diffraction methods have helped extend the limit of this approach.

Nanomedicine in The Netherlands - new report

Nanotechnology promises employment, sustainability and health. The Dutch government invests heavily in it. But how do we achieve these promises? In preparation for a parliamentary debate about nanotechnology on 21 April 2010, the Rathenau Institute initiated a working visit of MPs to one of the most promising areas of its application: healthcare.

Research team creates a quantum simulation that can be scaled to large systems

For most people, frustration is a condition to be avoided. But for scientists studying certain 'frustrated' ensembles of interacting components - that is, those which cannot settle into a state that minimizes each interaction - it may be the key to understanding a host of puzzling phenomena that affect systems from neural networks and social structures to protein folding and magnetism.
