Colorful eco-textiles thanks to nano-sized enzymes

The problems encountered by the traditional European dyes industry go from lack of innovation and weak market competitiveness to toxicity, environmental hazards and health risks for those working in it. To address them scientists have developed a new and environmentally friendly way to produce dyes.

Nanotechnology education is lacking in dermatology training

Members of the Nanodermatology Society (NDS), a physician-led organization dedicated to the scientific and medical aspects of nanotechnology and dermatology, recently published a pilot study evaluating knowledge, perceptions and attitudes regarding Nanotechnology amongst dermatologists in the United States.

Microspiders' polymerization reaction drives micromotors

Though it seems like science fiction, microscopic "factories" in which nanomachines produce tiny structures for miniaturized components or nanorobots that destroy tumor cells within the body and scrape blockages from our arteries may become reality in the foreseeable future. Nanomotors could transport drugs to specific target organs more rapidly or pilot analytes through the tiny channels on microchip diagnostic systems.

Digital quantum simulator realized

The physicists of the University of Innsbruck and the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck have come considerably closer to their goal to investigate complex phenomena in a model system: They have realized a digital, and therefore, universal quantum simulator in their laboratory, which can, in principle, simulate any physical system efficiently.

Physicists capture microscopic origins of thinning and thickening fluids

In things thick and thin: Cornell physicists explain how fluids -- such as paint or paste -- behave by observing how micron-sized suspended particles dance in real time. Using high-speed microscopy, the scientists unveil how these particles are responding to fluid flows from shear -- a specific way of stirring.

Superconductivity-related materials retain shape but change properties under strain

A University of Arkansas physicist and his colleagues have found that ultra-thin films of superconductors and related materials don't lose their fundamental properties when built under strain when built as atomically thin layers, an important step towards achieving artificially designed room temperature superconductivity. This ability will allow researchers to create new types of materials and properties and enable exotic electronic phases in ultra-thin films.

A diagnostic biological "computer" network incorporated in human cells

Researchers led by ETH professor Yaakov Benenson and MIT professor Ron Weiss have successfully incorporated a diagnostic biological "computer" network in human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction.
