First study to show that when counting frozen as well as fresh embryos, single embryo transfer does not reduce the chances of having a baby
Doctors in Australia have found that transferring one embryo instead of two during an IVF cycle does not reduce the chances of a woman having a baby, when frozen as well as fresh embryos are taken into account. Dr Jim Catt, Embryology director of Sydney IVF, Australia, and his colleagues have conducted the first study looking at cumulative... view more... (2003-06-27)

Genetic factors in smoking also increase risk of chronic bronchitis
Smoking is a known risk factor for respiratory diseases like chronic bronchitis, but genes also play a significant role in its development, according to researchers in Sweden, who studied more than 40,000 Swedish twins to determine the extent to which behavior, environment and genes each play a role ion the development of chronic bronchitis.   view more (2008-02-29)

Acid reflux is not just caused by lager and curry, but also our genes
Almost half the chance of developing acid reflux, which doctors refer to as GORD, may be down to our genes, and not just what we eat and drink, a twin study in Gut suggests. Acid reflux (gastro-oesophageal reflux disease) is one of the most common digestive disorders in the developed world. It is thought that up to one in five people suffers from... view more...

The penalty of having a sister — why sibling sex matters for male saiga antelopes
Having a twin sister could put male saiga antelopes at a reproductive disadvantage, says new research published today. The study shows that male twins with a sister are born lighter than those with a brother, making them smaller than the optimal size for males.   view more (2007-03-07)

Genes and environment interact in first graders to predict physical but not social aggression
