A team of researchers have made a major breakthrough in the understanding of the genetic composition of a parasite they believe might be used to stop the spread of disease.

Dubbed Wolbachia bacterium, the parasite can influence the reproductive trend among insects and even go on to influence their future generations

In an effort to cut the risk of developing embryos with genetic defects, British scientists have come up with a new test that would detect disorders in embryos before implantation.

The new rapid screening test is applicable only to embryos created through IVF

A research by experts at University of Oulu, Finland has shown that chances of conception by in vitro fertilization in women between 36 to 39 were as likely as in younger women, and may be safer.

According to a report by Press Association, researchers believe that it was the quality of the embryo that matters for a successful pregnancy rather than the age of mother

A new study compiled by a group of researchers from Indiana University Bloomington has said that mouse sperm cells are capable of tracking the faintest of scents. Sperm cells were bang on target, even when ovary extracts were extremely diluted.

Stephen C. Jacobson, who led the group of researchers, said in a press release, "sperm are known to exhibit chemotaxis toward extracts from various female reproductive organs, but the role of chemotaxis in reproduction is not known

Researchers have long been trying to uncover modern factors explaining the different life expectancies of men and women, however researchers from the University of Michigan say the gap is actually ancient and universal.

Daniel J. Kruger, a U-M research scientist says, "Women live longer in almost every country, and the sex difference in lifespan has been recognized since at least the mid-18th century. It isn't a recent trend; it originates from our deep evolutionary history
