A novel aerosol version of the most common tuberculosis (TB) vaccine, administered directly to the lungs as an oral mist, offers significantly better protection against the disease in experimental animals than a comparable dose of the traditional injected vaccine, researchers report this week in the Proceedings of the National Academy of Sciences.
NIST researchers reported at the March Meeting of the American Physical Society how they have improved manipulation of so-called block copolymers - polymers made of a mixture of two or more different molecule building blocks that are tethered at a junction point - which can form arrays of tiny dots that could be used as the basis for electronic components that pack terabytes (1000 gigabytes) of memory in something as small as a pack of gum.
Researchers in the United States and Austria report an advance toward the next generation of plastic solar cells, which are widely heralded as a low cost, environmentally-friendly alternative to inorganic solar cells for meeting rising energy demands.
In yet another twist on the strangeness of the nanoworld, researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park have discovered that materials such as silica that are quite brittle in bulk form behave as ductile as gold at the nanoscale. Their results may affect the design of future nanomachines.
Bottom-up manufacturing may hold the key to production of tiny medical devices capable of testing for multiple molecules like viruses or cancer markers, according to an interdisciplinary team of Penn State researchers.
'Tehran is ready to make available to Jakarta its achievements and its valuable experience in a variety of fields, including in nuclear engineering, nanotechnology and economics,' Mahmoud Ahmadinejad said at a joint news conference with Indonesian President Susilo Bambang Yudhoyono, who is on a two-day official visit to Tehran.
IMEC reports a variability-aware modeling (VAM) flow that analyzes process variability of sub-45nm technologies which enables designers to optimize their system design for timing, energy and yield versus expected application load.
MEDi 2008, the most comprehensive medical device conference and exhibition, will be held at the new Connecticut Convention Center in Hartford, Tuesday and Wednesday, September 9-10. MEDi 2008 will showcase the latest developments in nanomedicine, drug delivery vehicles, drug/device combination products, robotic surgery, orthopedic implants and prosthetic devices, artificial organs and eHealth, while also providing conferences addressing important issues and business challenges related to the manufacture and commercialization of these devices.
Food, packaging and agricultural products containing manufactured nanomaterials pose a toxic health risk and should be suspended from sale until new safety testing, laws and appropriate labelling are created, a new report says.
