Physicists at Brown University have developed a novel procedure to map a person's genome. They report in the journal Nanotechnology the first experiment to move a DNA chain through a nanopore using magnets. The approach is promising because it allows multiple segments of a DNA strand to be read simultaneously and accurately. Since the human genome was sequenced six years ago, the cost of producing a high-quality genome sequence has dropped precipitously. More recently, the National Institutes...

Chemists at New York University and Harvard University have created a bipedal, autonomous DNA "walker" that can mimic a cell's transportation system. The device, which marks a step toward more complex synthetic molecular motor systems, is described in the most recent issue of the journal Science. For a video demonstration of the walker, go to http://www.nyu.edu/public.affairs/videos/qtime/biped_movie.mov.Two fundamental components of life's building blocks are DNA, which encodes instructions...

Even within cells, the left hand knows what the right hand is doing. Molecular motors, the little engines that power cell mobility and the ability of cells to transport internal cargo, work together and in close coordination, according to a new finding by researchers at the University of Virginia. The work could have implications for the treatment of neurodegenerative disorders. "We found that molecular motors operate in an amazingly coordinated manner when moving an algal cell one way or the...

In an upcoming issue of Proceedings of the National Academy of Sciences, Yale researchers used newly developed mathematical models to analyze huge amounts of data on physical characteristics such as temperature and salinity in different ocean habitats and metabolic activity in marine micro-organisms. They were able to see in unprecedented detail how environment influences molecular changes within living organisms. As the technology dubbed "metagenomics" progresses, scientists might be able to...

By Hoppe, Adam D Shorte, Spencer L; Swanson, Joel A; Heintzmann, Rainer ABSTRACT Analysis of cellular pathways requires concentration measurements of dynamically interacting molecules within the three- dimensional (3D) space of single living cells. Forster resonance energy transfer (FRET) microscopy from widefield, from confocal, and potentially from superresolution microscopes can access this information; however, these measurements are distorted by the inherent 3D blurring of optical...

Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. That's the promise of artificial versions of photosynthesis, the process by which green plants have been converting solar energy into electrochemical energy for millions of years. To get there, however, scientists need a far better understanding of how nature does it, starting with...
