Early embryos yield stem cells,(photo courtesy of BBC news www.bbc.co.uk/news)
The Uk’s fertility regulator Human Fertilisation and Embryology Authority (HFEA) has given the green light to two teams of scientists for the creation of hybrid human-animal embryos.
Scientists, research institutions and patient groups have challenged the UK government for much of the last year: the Department of Health wanted […]

US researchers have recently discovered a new virus they believe may be linked to a rare but extremely lethal type of skin cancer. Merkel cell carcinoma mostly afflicts the elderly and people with weaker immune systems, including AIDS and transplant patients. The newly discovered virus belongs to the […]
In evolutionary terms bats and mice are separated by millions of years.
An MD Anderson team led by Dr Richard Behringer successfully switched the mouse Prx1 gene regulatory element with the Prx1 gene regulatory region from a bat - the resulting transgenic mice displayed abnormally long forelimbs.
While forelimb length is just one of several key […]
Grace at Kids Health Notes and Kristina at Autism Vox have both written about the gene CNTNAP2 being unequivocally implicated in Type 1 Autism.
In her article CNTNAP2, an autism susceptibility gene which I highly recommend, Kristina writes a personal account of her ongoing experience with her son Charlie’s autism and discusses the recent research findings.
Do read […]
Over the last month I have written articles on the rapid advances in genome sequencing (Knome) and SNP analyses (23andme and deCodeme), all of which are truly awesome. So when Helicos Biosciences announced it is on track to ship its first next generation sequencing unit called the HeliScope, very soon, it came as no surprise. However …. what […]
Male Down’s Syndrome with trisome at chromosome 21
People with Down’s Syndrome are less likey to get solid tumor cancers, research from Johns Hopkins University has revealed.
Up to 95% of Down’s syndrome cases are caused by “trisomy 21″, in which the baby has three, rather than two, copies of chromosome 21, and the hundreds of genes it […]
(Stylized rendering of a cross section of the AIDS virus)
New HIV infections are averaging around 2.5m per annum worldwide, and growing.
Most people infected with HIV produce antibodies against the virus within several weeks following infection, these antibodies rarely prevent the infection from progressing to symptomatic AIDS.
However a recent study involving a group of women from […]
Being able to sequence a human genome for $1,000 or less (which is the price most insurance companies are willing to pay) could open a new era in personal medicine, making it possible to precisely diagnose the cause of many diseases and tailor drugs and treatment procedures to the genetic make-up of an individual.
Professor Aleksei […]
Brain cells
I just love this following article which tells us that there could be enough computing ability in just one brain cell to allow human and animals to feel! There is one question that springs to mind, though … if we have so many billion neurons each with the capability of storing vast amounts of information … why […]
Further to my article on Fragile X Syndrome the BBC health website has posted this article:
“Genetic engineering has been used to alleviate symptoms Fragile X in mice, which is a leading cause of inherited learning difficulties and autism. There is currently no treatment for Fragile X syndrome, also linked to epilepsy and abnormal body growth, […]
