How sperm recognises the egg The discovery of a protein on mammalian sperm almost a decade ago, sparked the search for the corresponding receptor on the egg. Now researchers in the UK have found this receptor in mouse egg cells. They propose to call it Juno, after the Roman Goddess of fertility and marriage.

And in humans, it could lead to early screening of couple to decide which appropriate fertility treatment they require.Dogs as clinical models Dogs play an important companion role in society, but man's best friend can suffer from hundreds of different diseases.
