Spleen may be source of versatile stem cells
A year ago, Massachusetts General Hospital (MGH) researchers discovered that the spleen might be a source of adult stem cells that could regenerate the insulin-producing islets of thepancreas. In a follow-up to that unexpected finding, members of thesame team now report that these potential adult stem cells produce aprotein previously believed to be present only during the embryonicdevelopmen...Genes In The Interferon System Important In Systemic Lupus Erythematosus
Two genes with very strong associations withthe disease systemic lupus erythematosus (SLE) have been identified bya team of scientists headed by researchers at the Department of MedicalSciences at Uppsala University.

Throwing their lot with the group of scientists asking for more funding into stem cell research, 80 Nobel prize winners are faxing a letter to U.S. President George W. Bush asking him not to block stem cell research in any way. The debate on stem cell research is reaching a feverish pitch with both sides slamming each other on the pros and cons of stem cell research. While those...Passive smoking affects respiratory system
Scientists have produced strong evidence that passive smoking has a lasting impact on the respiratory systems of children. A team from the US National Center for Environmental Health in Atlanta studied data from 3,400 children aged 3 to 16 years.
