Cloned Dogs to Be Mated as Test

The world's first cloned dog will be mated with the world's second dog clone, in an experiment to see whether they can reproduce normally. // Snuppy, an Afghan hound who was the first dog to be created through a cloning process, will be mated later this year with second-in-line Bona, researche...

Herbal treatment should be estimated

According to a new study in Texas, Hay fever sufferers should be turning to their garden for help, not trying to avoid it,. The study has found that a herbal treatment called butterbur is as effective as antihistamines with less side effects. A team headed by Andreas Schapowal, from the Allergy ...

Scientists Use Non-Embryonic Stem Cells to Create Healthy Mice

... (out of the six lines available) successfully resulted in the production of dozens of healthy mouse pups. What's more, the iPS-generated pups were mated as adults and were fertile enough to produce more than 200 healthy offspring, who subsequently produced a third generation. The current work has no...

Environmental Toxin Causes Heritable Adult-Onset Diseases

...erm counts and a high incidence of adult-onset diseases. Despite their low fertility, those males were still able to produce offspring. When they were mated with females that had not been exposed to the toxins, their offspring had the same problems. The effect persisted through four generations, with about...

Why do we choose our mates? Ask Charles Darwin, prof says

For this research study, the scientists mated the tame with the aggressive rats and identified regions in the rat genome that cause a rat to be tamer or more aggressive. "For thousands of years...

Mating that causes injuries

...at these structures serve another purpose and that the injury is an unfortunate side effect. "Females' injuries as such do not benefit the male she mated with. It has been suggested rather that the injuries are a side effect of other benefits the males reap from the barbs. Now, for the first time, we a...

New research suggests diabetes transmitted from parents to children
