Keeping atherosclerosis in-check with novel targeted inflammation-resolving nanomedicines
Nanometer-sized 'drones' that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis, according to a study in pre-clinical models by scientists at Brigham and Women's Hospital and Columbia University Medical Center. These findings are published in the Feb. 18 online issue of Science Translational Medicine.

A novel approach for high performance field emission electron sources
Enhancing the electron emission of multi-wall carbon nanotubes (MWCNT) is key for applications ranging from cold cathodes used in high-resolution electron microscopes to portable X-ray imaging systems. In a paper recently published in Nanotechnology, a team led by professor My Ali El Khakani, from the Energie Matériaux Télécommunications Research Centre of INRS, has reported an original approach for the development of novel graphenated-MWCNTs with enhanced field electron emission properties.

Novel crumpling method takes flat graphene from 2-D to 3-D
Researchers at the University of Illinois at Urbana-Champaign have developed a unique single-step process to achieve three-dimensional texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3-D texturing, or 'crumpling,' allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.

Leading scholar presents advances in research of electric car batteries at AAAS
Lithium-sulphur batteries promise to extend the range of electric cars at least three times over current lithium ion cells and at much lower cost, making electric cars practical and potentially more appealing to a mass market. Linda Nazar, professor of chemistry from the Faculty of Science at the University of Waterloo, will present a perspective on the promise and reality of lithium-sulfur batteries at the American Association for the Advancement of Science Annual Meeting in San Jose, Calif.

Exotic states materialize with supercomputers
Supercomputers used to find new class of materials that exhibit exotic matter state known as the quantum spin Hall effect. The researchers published their results in the journal Science in December 2014, where they propose a new type of transistor made from these materials. They calculated state-of-the-art first principles approximation method on the XSEDE computational resources Stampede and Lonestar supercomputers of the Texas Advanced Computing Center.

Making teeth tough: Beavers show way to improve our enamel
Beavers don't brush their teeth or drink fluoridated water, but a new Northwestern University study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron. This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride. This discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.

DNA 'cage' could improve nanopore technology
Researchers from Brown University have designed a tiny cage that can trap a single strand of DNA after it has been pulled through a nanopore. While caged, biochemical experiments can be performed on the strand, which can then be zipped back through the nanopore. The device could enable researchers to look for probe a DNA before and after a reaction takes place.
