Speed limit on the quantum highway

A quantum computer based on quantum particles instead of classical bits, can in principle outperform any classical computer. However, it still remains an open question, how fast and how efficient quantum computers really may be able to work. A critical limitation will be given by the velocity with which a quantum signal can spread within a processing unit. For the first time, a group of physicists has succeeded in observing such a process in a solid-state like system.

Scientists create first free-standing 3-D cloak

Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality. Whilst previous studies have either been theoretical in nature or limited to the cloaking of two-dimensional objects, this study shows how ordinary objects can be cloaked in their natural environment in all directions and from all of an observer's positions.

Chemists synthesize artificial cell membrane

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life.

Protein folding game Foldit functionally remodels enzyme

Foldit, which was initially funded by DARPA, is a game with an online community of 240,000 players that allows non-experts and experts alike to collaborate and solve protein folding puzzles. Solutions to these puzzles are sent to biochemistry researchers to analyze for advances in protein design prediction.

National Research Council issues new nanotechnology risk report

Despite extensive investment in nanotechnology and increasing commercialization over the last decade, insufficient understanding remains about the environmental, health, and safety aspects of nanomaterials. Without a coordinated research plan to help guide efforts to manage and avoid potential risks, the future of safe and sustainable nanotechnology is uncertain, says a new report from the National Research Council.

Jupiter's Trojans on an atomic scale

The planet Jupiter keeps asteroids on stable orbits - and in a similar way, electrons can be stabilized in their orbit around the atomic nucleus. Calculations carried out at the Vienna University of Technology have now been verified in an experiment.

Hacking the SEM: Crystal phase detection for nanoscale samples

Custom modifications of equipment are an honored tradition of the research lab. In a recent paper, two materials scientists at the National Institute of Standards and Technology (NIST) describe how a relatively simple mod of a standard scanning electron microscope (SEM) enables a roughly 10-fold improvement in its ability to measure the crystal structure of nanoparticles and extremely thin films.
