Early diagnosis of a heart attack may now be possible using only a few drops of saliva and a new nano-bio-chip designed by John McDevitt, of the University of Texas. The nano-bio-chip assay, the size of a credit card, could be used to analyse a patient's saliva on board an ambulance, at the dentist's office or at a chemist's shop, helping save lives and prevent damage from cardiac disease.

Extracts from a mushroom used for centuries in Eastern Asian medicine may stop breast cancer cells from growing and could become a new weapon in the fight against the killer disease, scientists said. Laboratory tests using human breast cancer cells show the mushroom called Phellinus linteus has a marked anti-cancer effect, probably by blocking an enzyme called AKT. Dr Daniel Sliva of the Methodist Research Institute in Indianapolis said the it reduced uncontrolled growth of new cancer cells, suppressed their aggressive behavior and blocked new tumor-feeding blood vessels.

Out on the American farm, the ducks and pheasants are losing ground. Thousands of farmers are pulling their fields out of the government's biggest conservation program, spurning guaranteed annual payments for a chance to cash in on the boom in wheat, soybeans, corn and other crops.
