Biofuel cells without the bio cells

Scientists have observed a first: direct electricity-shuttling from a protein to a mineral. Reporting in the current advance online edition of the Journal of the American Chemical Society, they suggest that proteins -- removed from the outer membrane of a versatile, metal-altering soil bacterium -- could make miniature bioreactor cells feasible. Biologically speaking, the feat is the bacterial equivalent of removing lungs and coaxing the disembodied tissue to breathe.

1. Pittsburgh-based team engineers muscle, bone cell differentiation with aid of ink-jet printer
   12-10-2006 · EurekAlert!
   A team of researchers from Carnegie Mellon University and the University of Pittsburgh has created and used an innovative ink-jet system to print "bio-ink" patterns that direct muscle-derived stem cells from adult mice to differentiate into both muscle cells and bone cells. The results, which could revolutionize the design of replacement body tissues, will be presented Sunday, Dec. 10 at the 46th annual meeting of the American Society for Cell Biology in San Diego.

2. New 'biofuel cell' produces electricity from hydrogen in plain air
   03-26-2007 · EurekAlert!
   A pioneering "biofuel cell" that produces electricity from small amounts of hydrogen mixed in ordinary offers significant potential as an inexpensive and renewable alternative to the costly platinum-based fuel cells that have dominated discussion about the "hydrogen economy" of the future. The work will be described at the March national meeting of the American Chemical Society in Chicago.

3. A twist of fate -- Reprogrammed fibroblasts resemble embryonic stem cells
   06-06-2007 · EurekAlert!
   Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline.

4. Nano technique allows precise injection of living cells
   06-14-2007 · EurekAlert!
   Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells. For the first time, researchers at Rensselaer Polytechnic Institute have analyzed this nanoscale injection process on living cells and discovered that minor changes in the intensity of the laser could mark the difference between a healthy cell and a dead one.

7. Scientists find stem cell switch
   07-26-2007 · EurekAlert!
   Scientists have discovered how plant stem cells in roots detect soil structure and whether it is favourable for growth. Poor soil structure is a problem in tropical agriculture, where soil becomes compact as it dries out. Professor Liam Dolan, of the John Innes Centre in Norwich, UK and his team determined that the plant hormone ethylene regulates cell division in root stem cells.

8. Forsyth scientists gain new understanding of adult stem cell regulation
   08-01-2007 · EurekAlert!
   Forsyth Institute scientists have discovered an important mechanism for controlling the behavior of adult stem cells. Research with the flatworm, planaria, found a novel role for the proteins involved in cell-to-cell communication. This work has the potential to help scientists understand the nature of the messages that control stem cell regulation -- such as the message that maintain and tells a stem cell to specialize and to become part of an organ (e.g., liver or skin).
