In the 7 Feb. 2010 issue of the journal Nature, scientists at the Genome Institute of Singapore (GIS), report that a genetic molecule, called Tbx3, which is crucial for many aspects of early developmental processes in mammals, significantly improves the quality of stem cells that have been reprogrammed from differentiated cells.

Tiny circles of DNA are the key to a new and easier way to transform stem cells from human fat into induced pluripotent stem cells for use in regenerative medicine, say scientists at the Stanford University School of Medicine. Unlike other commonly used techniques, the method, which is based on standard molecular biology practices, does not use viruses to introduce genes into the cells or permanently alter a cell's genome.

High-coverage human papillomavirus (HPV) vaccinations among adolescents and young women may result in a rapid reduction of genital warts, cervical cell abnormalities, and diagnostic and therapeutic procedures, researchers report in a new study published online February 5 in the Journal of the National Cancer Institute. Some of these genital abnormalities are precursors of cervical, vulvar, and vaginal cancers.

(PhysOrg.com) -- How two butterfly species have evolved exactly the same striking wing colour and pattern has intrigued biologists since Darwin's day. Now, scientists at Cambridge have found 'hotspots' in the butterflies' genes that they believe will explain one of the most extraordinary examples of mimicry in the natural world.

JamJam writes "The Lancet, a major British medical journal, has retracted a flawed study linking the measles, mumps, and rubella vaccine to autism and bowel disease. British surgeon and medical researcher Andrew Wakefield and his colleagues originally released their study in 1998. Since then 10 of Wakefield's 13 co-authors have renounced the study's conclusions and The Lancet has said it should never have published the research. Wakefield now faces being stripped of his right to practice medicine in Britain. The vaccine-autism debate should now end."
