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.
It's official: The world's fastest movie was shot by DESY's X-ray laser FLASH in Hamburg. In its 2012 edition, the famous Guinness Book of World Records lists an interval of a mere 50 femtoseconds between two frames for FLASH.
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.
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.
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.
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.
A team of physicists from the Joint Quantum Institute (JQI), the Neils Bohr Institute in Copenhagen, Denmark, and Harvard University has developed a theory describing how to both detect weak electrical signals and cool electrical circuits using light and something very like a nanosized loudspeaker.
A University of Arkansas physicist and his colleagues have examined the challenges facing scientists building the next generation of materials and innovative electronic devices and identified opportunities for taking the rational material design in new directions.
At the Molecular Foundry, Berkeley Lab's acclaimed nanotechnology research center, Ren has pushed his Zeiss Libra 120 Cryo-Tem microscope to resolutions never envisioned by its German manufacturers, producing detailed snapshots of individual molecules. Today, he and his colleague Lei Zhang are reporting the first 3-D images of an individual protein ever obtained with enough clarity to determine its structure.
