New improved processes, doubling the capacity of Pfizer's biotechnology facility in Strangeness. Now the factory is rewarded with a prestigious award.

Researchers in Japan have for the first time demonstrated that stem cells themselves can form new, complex body.  Stem cells from mice were developed in the lab to the precursor of a retina.

The primitive eye, which is published in this week's issue of the journal Nature, is the most advanced bodies so far made in the laboratory from embryonic stem cells.

esearchers at the Japanese research institute Riken started from embryonic stem cells from mice that were cultivated in a carefully selected environment.  The cells were divided and unorganized spontaneously to a three-dimensional structure with several layers of cells.

The whole thing is similar to how the eye develops naturally in the womb. The outer layer consists of a pigment-filled tissue that provides support to an inner layer where the light-sensitive pins and rods are. The next step is to test whether the retina can also register light and leading impulses on. It is hoped that the research will lead to new implants that can be formed by human stem cells.

Genetically modified bacteria make hydrogen from light

By blocking the ability of certain bacteria that fix carbon dioxide during photosynthesis can get them to produce hydrogen for use in fuel cells. Hydrogen is a promising transportation fuel, using only water as waste product.
