An air-breathing bio-battery has been constructed by researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw. The core element providing the new power source with relatively high voltage and long lifetime is a carefully designed cathode taking up oxygen from air and composed of an enzyme, carbon nanotubes and silicate.
In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms.

The organizers of ImagineNano are pleased to announce France as the Invited Country at this year’s edition. Forty French invited speakers among 7 conferences and a pavilion featuring the nanoscience & nanotechn...
Scientists at Contipro have created materials that can be programmed to function for a specific duration in the body before being fully absorbed. They have also developed the new apparatus 4SPIN, capable of creating structured nanofibers from such materials.
Phillip B. Messersmith, a biomedical engineer at Northwestern University who takes inspiration from nature to develop new materials, will be the featured speaker at the University’s nanotechnology town hall meeting Monday, Feb. 18.
Physicists of the University of Vienna together with researchers from the University of Natural Resources and Life Sciences Vienna developed nano-machines which recreate principal activities of proteins. They present the first versatile and modular example of a fully artificial protein-mimetic model system, thanks to the Vienna Scientific Cluster (VSC), a high performance computing infrastructure. These "bionic proteins" could play an important role in innovating pharmaceutical research. The results have now been published in the renowned journal "Physical Review Letters".
Miniaturized laboratory-on-chip systems promise rapid, sensitive, and multiplexed detection of biological samples for medical diagnostics, drug discovery, and high-throughput screening. Using micro-fabrication techniques and incorporating a unique design of transistor-based heating, researchers at the University of Illinois at Urbana-Champaign are further advancing the use of silicon transistor and electronics into chemistry and biology for point-of-care diagnostics.
MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell’s DNA and passed on for dozens of generations.
With the recent launch of MIT’s Institute for Medical Engineering and Science, MIT News examines research with the potential to reshape medicine and health care through new scientific knowledge, novel treatments and products, better management of medical data, and improvements in health-care delivery.
An external panel of venture capitalists, entrepreneurs and medical device manufacturers has awarded $100,000 grants to two joint Arizona State University-Mayo Clinic research teams that are working to apply personalized medicine to the treatment of Alzheimer’s disease and cerebral aneurysms.
