'Dayglo', the latest play by the Y Touring Theatre Company, skilfully and thoughtfully explores pharmacogenetics, and is much more than just another educational story...

TV Review: Brave New World - Health

31 October 2011 - by Louisa Petchey

'Science is on the brink of changing your life'. It's a bold and risky opening statement, but I find my initial scepticism quelled. Whether this is due to the promise coming from the revered Professor Stephen Hawking, or because I've allowed myself to get caught up in the increasingly dramatic soundtrack is hard to say. But either way, the addition of flashy sound bites from enthusiastic scientific celebrities coupled with epic landscape shots from exotic destinations is sufficient to convinc... [Read More]

US bioethics panel urges privacy protection in new era of genome sequencing

15 October 2012 - by Louisa Petchey

Whole genome sequencing is getting faster and cheaper but the huge healthcare benefits this data promises must be balanced by policies that protect patient privacy, says a report by the President's Commission of Bioethics in the USA... [Read More]

The most extensive catalogue of the trillions of microbes that live in and on humans - called the human microbiome - has been published by an international team of scientists... [Read More]

Melanoma sequencing reveals genetic effects of sun damage

15 May 2012 - by Louisa Petchey

Whole genome sequencing of melanoma, the deadliest form of skin cancer, has confirmed the long held belief that greater sun exposure raises cancer risk by increasing the frequency of genetic mutation. The study also identifies one gene, PREX2, that is mutated in 14 percent of cases... [Read More]

IVF increases risk of pre-eclampsia by 40 percent, study claims

24 October 2011 - by Louisa Petchey

Women who have conceived through IVF may be more likely to develop pre-eclampsia during pregnancy than pregnant women who have not, according to a recent study in the US. The researchers, who are presenting their findings at this year's American Society for Reproductive Medicine conference in Orlando, suggest exposing embryos to laboratory conditions during IVF may lead to poor development of the placenta and its blood supply....
