DNA Molecules Used To Assemble Nanoparticles

...ll, either killing it from within or sending out a signal to identify it. But making the particles is notoriously difficult and time-consuming. The nanoparticle system used by Baker's lab is based on dendrimers, star-like synthetic polymers that can carry a vast array of molecules on the ends of their arms...

Researchers discover way to make cells in the eye sensitive to light

...ly, but the retinal ganglion cells, thecells which signal to the brain, remain intact. The researchers believethat by activating the melanopsin, these cells may gain the ability tosense and respond to light.Professor Mark Hankins, from Imperial College London and Charing CrossHospital, and one of the papers...

...les would be closeenough together to create a FRET signal at all," says Maag. "We werevery pleased just to be able to monitor it, and then we were surprisedand pleased by what we saw next."They had expected -- or at least hoped -- to see a shift in the colorof light once the RNA was mixed in. Instead, they ...

Researchers Uncover Key Step In Manufacture of Memory Protein

... be secreted. Once the cell receives an electrical signal from another neuron, these vesicles fuse with the cell’s outer membrane, open up, and release mBDNF. During their research, Dr. Loh and her colleagues observed mice genetically incapable of producing CPE. In these mice, proBDNF could not be delivere...

Color-blind method opens new doors in DNA sequencing

...E gives brighter signals and collects more of that signal by eliminating the need for a prism to separate the light into colors." Metzker is also seeking to develop a chip-based imager than could be used in his overall project on sequencing-by-synthesis (SBS), which is funded by the National Human Genome R...

BRCA1 causes ovarian cancer through indirect, biochemical route
