Angewandte Chemie
The cyborgs era has started
Medical implants, complex interfaces between brain and machine or remotely controlled insects: Recent developments combining machines and organisms have great potentials, but also give rise to major ethical concerns. In their review entitled "The Chemistry of Cyborgs -- Interfacing Technical Devices with Organisms," KIT scientists discuss the state of the art of research, opportunities, and risks. The review is published now by the renowned journal Angewandte Chemie International Edition.

KIT researchers develop artificial bone marrow
Artificial bone marrow may be used to reproduce hematopoietic stem cells. A prototype has now been developed by scientists of KIT, the Max Planck Institute for Intelligent Systems, Stuttgart, and Tübingen University. The porous structure possesses essential properties of natural bone marrow and can be used for the reproduction of stem cells at the laboratory. This might facilitate the treatment of leukemia in a few years.

Battery development may extend range of electric cars
Electric cars could travel farther on a single charge and more renewable energy could be saved for a rainy day if lithium-sulfur batteries can last longer. PNNL has developed a novel anode that could quadruple the lifespan of these promising batteries.

Penn research helps lay out theory for metamaterials that act as an analog computer
A new study shows that metamaterials can be designed to do "photonic calculus" as a light wave goes through them. A light wave, when described in terms of space and time, has a profile that can be thought of as a curve on a Cartesian plane. This theoretical material can perform a specific mathematical operation on that wave's profile, such as finding its derivative, as the light wave passes through the material.

Columbia Engineering wins $3 million ARPA-E grant to raise efficiency, lower cost of power grid
A team led by Ken Shepard has won a $3 million ARPA-E grant for research targeted at developing next-generation power conversion devices that could dramatically transform how power is controlled and converted throughout the grid. Shepard is working with colleagues at MIT, IBM, and Veeco Instruments to develop a new method to fabricate vertical gallium nitride devices in a low-cost matter compatible with traditional silicon semiconductor manufacturing.

Researchers find that computer components can be damaged by key manufacturing processes
Manufacturers of increasingly minute computer chips, transistors and other products will have to take special note of research findings at the University of Huddersfield. The implications are that a key process used to transform the properties of nanoscale materials can cause much greater damage than previously realized.

Penn researchers grow liquid crystal 'flowers' that can be used as lenses
A team of material scientists, chemical engineers and physicists from the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures. Their earlier studies produced patterns of "defects," useful disruptions in the repeating patterns found in liquid crystals, in nanoscale grids and rings. The new study adds a more complex pattern out of an even simpler template: a three-dimensional array shaped like a flower.

DNA clamp to grab cancer before it develops
As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology. The results of this research is published this month in the journal ACS Nano.

Survey reveals regulatory agencies viewed as unprepared for nanotechnology
Three stakeholder groups agree that regulators are not adequately prepared to manage the risks posed by nanotechnology, according to a paper published in the peer-reviewed journal PLOS One. In a survey of nano-scientists and engineers, nano-environmental health and safety scientists, and regulators, researchers at the UCSB Center for Nanotechnology in Society and at the University of British Columbia found that those who perceive the risks posed by nanotechnology as "novel" are more likely to believe that regulators are unprepared.

UCLA researcher highlights advances in nanotechnology's fight against cancer
Among the most promising advances in the fight against cancer has been the rise of nanomedicine, the application of tiny materials and devices to detect, diagnose and treat disease. Researchers from the UCLA School of Dentistry and the National University of Singapore provide one of the most comprehensive assessments to date of research on nanomedicine-based approaches to treating cancer and offers insight into how researchers can best position nanomedicine-based cancer treatments for FDA approval.
