San Diego, CA, USA. In a significant leap forward in the understanding the development of specific tissue types in mammals, an international team of scientists succeeded in mapping the entire network of DNA-binding transcription factors and their interactions. This global network, indicating which factors can combine to determine cell fate, appears in the journal Cell.
Transcription factors (TFs) are proteins that bind to specific DNA sequences in order to direct which genes should be turned on or off in a tissue. Tissue specificity (e.g. whether embryonic tissue develops into lungs or kidneys or skin) is determined by how and which TFs bind to genes.
Between 2,000 and 3,000 transcription factor proteins are encoded by the human genome, potentially creating more than 4 million potential protein pairings.

Washington, DC, USA. In Michigan, where many enterprises are struggling to survive, the renowned University of Michigan is in the midst of a construction boom and hiring spree.
Michigan State University, on the other hand, plans to lay off faculty and cut programs, blaming state funding that is lower than it was a decade ago.
Flagship universities in other states, including Colorado, Virginia, Vermont and Wisconsin, are also prospering, while their lesser-known counterparts suffer from |

Washington, DC, USA. Indiana soon could join at least 11 other states and allow residents to bring their guns to work, as long as they are stored out of sight in their cars. But a shooting in Portage, Ind., last week — in which a state worker frustrated over a poor performance review retrieved a gun from his car and fired at coworkers — is causing opponents to ramp up their pressure on Governor Mitch Daniels to veto the bill.
“This is further evidence that guns and the workplace si |

Stanford, CA, USA. Human blood is a trove of biological information, now accessible by a software algorithm that enables a common laboratory device to virtually separate a whole-blood sample into its different cell types.
This development has a near-term potential for adding a powerful tool to the toolset for biological investigations. The algorithm enables detection of medically important gene-activity changes that are specific to any one of the cell types present in the blood sample. T |

Vancouver, BC, CAN. People undergoing severe stress can resort to the use of anti-depressant drugs, but some of the same medications are associated with an increased chance of developing cataracts, according to a new statistical study by researchers at the University of British Columbia (UBC), Vancouver Coastal Health Research Institute and McGill University.
More than 200,000 Quebec residents aged 65 and older were in the database, with statistical relationships between a diagnosis of c |

Washington, DC, USA. Sixteen states raised their cigarette taxes last year to generate more revenue, and the trend shows few signs of slowing down in 2010. Georgia, Kansas, South Carolina and Utah are among the states that could force smokers to pay more as they try to balance their budgets.
Anti-tax activist Grover Norquist will lead a rally on the steps of the Georgia Capitol today (March 9) to protest a legislative plan to raise cigarette taxes by $1 per pack, to $1.37. The event is s |
