According to a study reported in the American Journal of Obstetrics and Gynecology, twins conceived through in vitro fertilisation (IVF) are more likely to be born prematurely and delivered by Caesarean than those conceived through sexual intercourse. Researchers at the University of Ottawa, Ontario, Canada compared 2,302 twins conceived through...
According to research published in the British Journal of Obstetrics and Gynaecology, women who deliver their first child through a Caesarean are more likely not to get pregnant again. In addition, those who do conceive a second time may take longer to do so, say the scientists. A study performed...
US President George Bush has restated his intention to veto any new law extending his policy on human embryonic stem (ES) cell research, if the Senate passes it. Current policy, set by the President on 9 August 2001, only allows state funds to be used for research on ES cell...
Three-week old Jodie Fletcher, the first 'saviour sibling' conceived in the UK, is a perfect genetic match for her three-year old brother, Joshua, who suffers from Diamond Blackfan anaemia (DBA), an incurable blood disorder. In September 2004, the Human Fertilisation and Embryology Authority (HFEA) granted Joe and Julie Fletcher permission...
Scientists at the University of Pittsburgh, US, report that they have discovered that amniotic epithelial (AE) cells, found in the human placenta, have properties similar to those of embryonic stem (ES) cells. Like ES cells, the AE cells can develop into a number of different tissues. The team, led by...
After much patience and perseverance, dogs can now officially be added to the list of animals, including sheep, cats and horses, that have been successfully cloned. Researchers in South Korea led by Professor Woo Suk Hwang - the team that created the world's first cloned human embryos - have cloned an Afghan...
Advances in genome sequencing technologies are bringing scientists one step closer to a time when it would cost as little as $1000 to read the entire genetic code of a person, two US teams say. A group based at Harvard Medical School has developed a method using beads and fluorescent...
Scientists at the National Institute of Genomic Medicine in Mexico launched the Mexico Genome Project last week. They hope the study, the first phase of which is expected to cost $2.5 million, will identify genes involved in common conditions such as diabetes, asthma and high blood pressure. Gerardo Jimenez, who...
