Canadian researchers have discovered that women who have a high probability of developing ovarian cancer might be able to reduce the risk by having their Fallopian tubes tied. They have shown that tubal ligation surgery is an alternative to the removal of ovaries in young women with mutations in the...
New embryo research guidelines were issued last week by the main research funding agency in Germany, the Deutsche Forschungsgemeinschaft (DFG). The guidelines would allow German researchers to use imported human embryonic stem cells. Currently, Germany law allows scientists to work on fetal stem cells but not those derived from embryos...
Researchers at the Whitehead Institute for Genome Research in Cambridge, Massachusetts have found that the majority of people of Northern European ancestry are likely to be descendants of a tiny prehistoric population. They used a technique made possible by the Human Genome Project (HGP) to show that Northern Europeans went...

Rival scientists and companies have been challenged to a 'gene count' showdown. In February, draft sequences of the entire human genome were published by the publicly funded human genome project (HGP) and Celera Genomics, both estimating the total number of genes to be between 30,000 and 40,000. But some biotech...
