Good mothering can cancel out a genetic predisposition to aggressive behaviour in monkeys, a new US study suggests. Scientists at the National Institutes of Health say that a nurturing environment can curb antisocial behaviour in rhesus monkeys born with low levels of certain brain chemicals. Their findings, which will be...
US scientists have uncovered the genetic basis of a form of sudden infant death syndrome (SIDS) - or 'cot death' - associated with testes abnormalities. Team leader Dietrich Stephan says the findings, which will appear in the Proceedings of the National Academy of Sciences, could help save some babies at risk of...
The Human Fertilisation and Embryology Authority (HFEA) has decided that no distinction should be between the cases of the Hashmi family and the Whitaker family: that preimplantation genetic diagnosis (PGD) for the sole purpose of tissue typing should be allowed. The news gives hope to many families who may now...
Environmental and genetic factors are both important triggers in the development of late-onset Alzheimer's disease (AD), a new US study of twins confirms. Researchers at Duke University Medical Centre presented their research, carried out on more than 200 male twins who served during World War II, at the recent International...
A research team from Cold Spring Harbour Laboratory has found a surprising degree of variation in repeated regions of the human genome. The discovery was made whilst researchers were looking for repeated DNA that might cause cancer, using a new laboratory technique. The results, published this week in the journal...
An independent television production company, based in the UK, has announced that it is in the process of developing a reality television in which men compete in a 'sperm race' to get a childless woman pregnant. The company - Brighter Pictures - is owned by Endemol, the company that produces Big Brother...
Researchers have overcome one of the major hurdles in using gene therapy to treat muscle diseases: delivery of the gene to muscles throughout the body. The study, to be published in the journal Nature Medicine next month, is further progress towards treating diseases such as Duchenne muscular dystrophy (DMD), which...
The Human Fertilisation and Embryology Authority (HFEA) is to merge with the proposed Human Tissue Authority (HTA) to become the Regulatory Authority for Fertility and Tissue (RAFT). The amalgamation of these two bodies is part of the Department of Health's (DoH) review of Arm's Length Bodies (ALB), which the Health...

Saviour siblings: have we slipped down the slope?
by Juliet Tizzard
The Human Fertilisation and Embryology Authority (HFEA) has announced a relaxation of the rules surrounding PGD and tissue typing, otherwise known as saviour siblings treatment. Predictably, the decision prompted a rash of media comment. But, perhaps unpredictably, nearly all the comment was positive and in support of the HFEA's decision...
Embryo freezing: is it safe?
by Dr Maureen Wood
Embryo freezing is generally seen as a routine part of IVF and ICSI treatment. It offers many benefits, not least the fact that embryos left over from a fresh cycle can be stored for future use. This has implications for the patient's health and wellbeing - it avoids unnecessary gonadotrophin stimulation...
