Arguably the oddest beast in Nature’s menagerie, the platypus looks as it if were assembled from spare parts left over after the animal kingdom was otherwise complete.
Now scientists know why. According to a study released Wednesday, the egg-laying critter is a genetic potpourri — part bird, part reptile and part lactating mammal.
The task of laying [...]

US scientists say they have produced embryos that are clones of two men, in an attempt to produce patient-specific stem cells.
Researchers removed DNA from donated human eggs, and replaced it with DNA from the skin cells of two volunteers.
They produced embryos with genetic material that matched the men’s, but did not go on to [...]

The textbook rule that says activated human genes almost always express both of their copies — the one inherited from mum and that inherited from dad — seems not to be true. Instead, a good chunk of our genome could prefer the ’single life’, according to new research.
Whether the maternal or paternal copy gets switched [...]
