First in human nanotherapy brain cancer trial launched at CTRC
A CTRC neurosurgeon used a tiny catheter to insert radioactive liposomes, only 100 nanometers across, into the stubborn tumor in David Williams' brain. The therapy, developed at the CTRC in San Antonio, offers hope to those suffering from the most devastating brain cancers, and could be expanded to treat other types of cancer as well.

Nanospheres cooled with light to explore the limits of quantum physics
A team of scientists at UCL led by Peter Barker and Tania Monteiro has developed a new technology which could one day create quantum phenomena in objects far larger than any achieved so far. The team successfully suspended glass particles 400 nanometers across in a vacuum using an electric field, then used lasers to cool them to within a few degrees of absolute zero. These are the key prerequisites for making an object behave according to quantum principles.

Imperfect graphene opens door to better fuel cells
A major challenge in fuel cell technology is efficiently separating protons from hydrogen. In a study of single-layer graphene and water, Northwestern University researchers found that slightly imperfect graphene, with just a few tiny holes, shuttles protons -- and only protons -- from one side of the graphene membrane to the other in mere seconds. The membrane's speed and selectivity are much better than that of conventional membranes, offering engineers a new and simpler mechanism for fuel cell design.

Graphene 'gateway' discovery opens possibilities for improved energy technologies
Graphene, a strong, lightweight carbon honeycombed structure, only one atom thick, holds great promise for energy research and development. Recently scientists with the Fluid Interface Reactions, Structures, and Transport Energy Frontier Research Center, led by the US Department of Energy's Oak Ridge National Laboratory, revealed graphene can serve as a proton-selective permeable membrane, providing a new basis for streamlined and more efficient energy technologies such as improved fuel cells.

'Additive manufacturing' could greatly improve diabetes management
Using a process similar to ink jet printing, engineers have created an improved type of glucose sensor for people with type 1 diabetes. It will be part of an 'artificial pancreas' system that should work better, cost less and be more comfortable, and may find use by diabetic patients around the world.

Spherical nucleic acids set stage for new paradigm in drug development
A Northwestern University-led research team led is the first to show spherical nucleic acids (SNAs) can be used as potent drugs to effectively train the immune system to fight disease, by either boosting or dampening the immune response. By increasing the immune response toward a specific cell type, SNAs could be used to target anything from influenza to different forms of cancer. If used to suppress the immune response, SNAs could target autoimmune disorders, such as rheumatoid arthritis and psoriasis.

Catalyst destroys common toxic nerve agents quickly
Northwestern University scientists have developed a robust new material, inspired by biological catalysts, that is extraordinarily effective at destroying toxic nerve agents that are a threat around the globe. The material, a zirconium-based metal-organic framework, degrades in minutes one of the most toxic chemical agents known to mankind: Soman, a more toxic relative of sarin. Computer simulations show the MOF should be effective against other easy-to-make agents, such as VX.

Molecular ruler sets bacterial needle length
University of Utah biologists report how a disposable molecular ruler or tape measure determines the length of the needle salmonella bacteria use to infect target cells. The findings have potential long-term applications for developing new antibiotics and anticancer drugs and for helping people design machines at the nanoscopic or molecular scale.

New technology may double radio frequency data capacity
Columbia engineers have invented a technology -- full-duplex radio integrated circuits -- that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies. Electrical engineering professor Harish Krishnaswamy's team is the first to demonstrate an IC that can accomplish this.

High performance, lightweight supercapacitor electrodes of the future
Many scientists are working to develop green, lightweight, low-cost supercapacitors with high performance, and now two researchers from the S.N. Bose National Centre for Basic Sciences, India, have developed a novel supercapacitor electrode based on a hybrid nanostructure made from a hybrid nickel oxide-iron oxide exterior shell and a conductive iron-nickel core. Its core/shell structure could mean faster charging time and longer battery life in electric vehicles and portable electronics.
