Biofuel research boosted by discovery of how cyanobacteria make energy

Posted: 15 Dec 2011 11:16 AM PST

Research expected to help scientists to discover new ways of genetically engineering bacteria to manufacture biofuels overturns a generally accepted 44-year-old assumption about how certain kinds of bacteria make energy and synthesize cell materials. With this better understanding of how cyanobacteria make energy, it might be possible to genetically engineer a cyanobacterial strain to synthesize 1,3-butanediol -- an organic compound that is the precursor for making not only biofuels but also plastics.

New light on medicinal benefits of plants

Scientists are about to make publicly available all the data they have so far on the genetic blueprint of medicinal plants and what beneficial properties are encoded.

How cells limit inflammation in lung injury

Researchers have found in an animal model of acute lung injury a molecular mechanism that allows cells of the immune system to reduce tissue damage from inflammation.

New genetic program converts static cells into mobile invasive cells

Posted: 15 Dec 2011 06:48 AM PST

Researchers have identified the gene GATA 6 as responsible for epithelial cells -which group together and are static- losing adhesion and moving towards a new site. This process, which is common to developing organisms, is very similar to one that occurs in metastasis, when tumor cells escape from the original tumor and invade new tissue.
