Artificial Golgi may provide new insight into key cell structure

Scientists in New York and North Carolina are reporting assembly of the first functioning prototype of an artificial Golgi organelle. That key structure inside cells helps process and package hormones, enzymes, and other substances that allow the body to function normally.

A multifunctional storage device for light

Physicists have for the first time realized a microresonator that combines all the desired properties, i.e., long storage time, small volume, and tunability to arbitrary optical frequencies, in a single monolithic device.

Nanoparticles affect brain development in mice

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.

Jet-propelled imaging for an ultrafast light source

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.

Tiny X-ray tubes for cancer research packed with carbon nanotubes

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.

Nanoparticles package cancer-killing isotopes and deliver them into cancer cells

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.
