...hoice and male contest could come into action. The experiment was carried out on fruit flies of a wide variety of age groups. The scientists measured offspring in terms of their viability, their wing size, asymmetry of features and the number of tooths on their sex combs which are used to purport females. The ...

Failure of Drug-Coated Stent

...at risk of a heart attack. The stents used in his experiment had a relatively thick plastic sleeve. The body's cells may have attacked the plastic, thinking it was a foreign body, leading to an accumulation of cells. The reblockage of the vessels could be a reaction to the plastic sleeve, and not necessarily a...

Herbs With Estrogen Action Aggravate Cancer Risk

Researchers also suggests that the women should err on the side of caution and approach the use of these herbs judiciously, particularly if they are at risk for any estrogen-related cancers. This ...

Passive smoking may be harmless

...ase the risk for lung cancer and heart disease. An experiment was conducted on more than 35,000 California residents. Those who were part of the study were non-smokers, but their spouses were active smokers. The researchers said they found no significant increase in the death rate from heart disease, lung cance...

Stem cells offer hope for muscular dystrophy

...niversity of Pavia, who worked on the study. The experiment proves a theory but some real-world stumbling blocks remain. For instance, the approach would work best if a patient's own mesoangioblasts were used, but these cells have so far only been isolated from fetuses. "I'm convinced this is an important res...

Islets May Lead to Diabetes Cure

A separate experiment also found the regrowth of islet cells can occur in animals that have immune system re-education to eradicate their diabetes, but do not receive the donor cells.Researchers have developed a protocol to test this approach in humans, but additional gra...
