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.

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.

Under the electron microscope - a 3D image of an individual protein

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.
