Maternal exposure to nanoparticles of titanium dioxide (TiO2) affects the expression of genes related to the central nervous system in developing mice. Researchers writing in BioMed Central?s open access journal Particle and Fibre Toxicology found that mice whose mothers were injected with the nanoparticles while pregnant showed alteration in gene expression related to neurological dysfunction.
A particle gun that fires liquid droplets less than a millionth of a meter in diameter, faster than hundreds of thousands of times a second, is poised to revolutionize biological imaging. Tested at Berkeley Lab?s Advanced Light Source and soon to be installed at SLAC?s Linac Coherent Light Source, the sample jet injects a beam of droplets across a tightly focused x-ray beam in single file, each droplet so small it contains only a single protein or virus.
The tubes that power X-ray machines are shrinking, improving the clarity and detail of their Superman-like vision. A team of nanomaterial scientists, medical physicists, and cancer biologists at the University of North Carolina has developed new lower-cost X-ray tubes packed with sharp-tipped carbon nanotubes for cancer research and treatment.
A group of researchers at Johns Hopkins University has designed nanoparticles that can carry cancer-treating radioisotopes through the body and deliver them selectively to tumors. Today in Anaheim, CA, they will report the latest results of their research, including studies in animal models, at the 51st meeting of the American Association of Physicists in Medicine.
Ways to make lasers smaller are being discovered through collaborative efforts of researchers at Arizona State University (ASU) and Technical University of Eindhoven in the Netherlands. The work opens up possibilities for using nanoscale lasers to significantly improve the performance of computers and speed up Internet access.
Michigan State University (MSU) researchers have developed a composite material modified with nanoparticles that is economical and could also help automakers meet the new fuel efficiency standards recently announced by President Barack Obama.
The National Physical Laboratory (NPL) and the University of Surrey have signed an agreement to collaborate on the delivery of a GBP10m programme to translate the results of research into innovation that makes a real-world difference.
Chemists and engineers at the University of Warwick have found that exposing particular mixtures of polymer particles and other materials to sudden freeze-drying can create a high-tech armored foam that could be used for a number of purposes, including a new range of low power room temperature gas sensors.
FIZ Karlsruhe offers ICSD, the world's largest database with fully identified inorganic crystal structures / evaluated data of unique quality / customized access options and new web presence with cutting-edge search and analysis functions.
Researchers at Argonne National Laboratory's Midwest Center for Structural Genomics recently hit a milestone. They imaged more than 1,000 proteins, the building blocks of life. It is a feat that helps a wide array of scientists better understand dangerous pathogens as well as the basic mechanisms of human and organism survival.
At the International Conference on Magnetism today in Karlsruhe, Germany, IBM Fellow Stuart Parkin received the International Union of Pure and Applied Physics Magnetism award and the Louis Neel Medal for his pioneering work and fundamental contributions to the development of spintronic nano-materials and nano-devices for magnetic sensing, memory and logic devices.
Oxford scientists have created a transparent form of aluminium by bombarding the metal with the world's most powerful soft X-ray laser. 'Transparent aluminium' previously only existed in science fiction, featuring in the movie Star Trek IV, but the real material is an exotic new state of matter with implications for planetary science and nuclear fusion.
