...There is a very large gap between recognizing how addiction looks on a brain scan and developing therapies that are effective enough to safely abolish addictive behavior. Once a safe and effective candidate drug is discovered, a minimum of five years is needed before the Food and Drug Administration can deem it safe to administer to millions of addicts. We are at least a decade away from even starting such trials. Addiction is a side effect of the positive evolutionary pressures to respond to pleasurable stimuli by seeking repeat stimulation. Alcoholics Anonymous is one form of therapy that...
...happening in Queensland's clouds before, during and after materials like silver iodide and salt are sprayed into them from planes. Working in tandem with other ground radars and forecasting equipment, the technology will be able to do a three-dimensional reading of the atmosphere - similar to a body scan. Not only will this mean better information about when conditions are right to send the seeding planes, but it will enable scientists to "watch" how the water and ice particles in the cloud are affected by the chemical. "This has not been done in any program anywhere in the world...

...routinely used diagnostic nuclear stress test, which also detects plaque deposits, but only those that are big enough to block 70% of the artery. "The risk-benefit assessment is in favor of cardiac CT to be used in a judicious fashion," says Lepor, who describes good candidates for the scan as male, over age 40 with at least one risk factor. But there's no need to image patients who don't have any risk factors. "This is not a test that should be done in any routine or repetitive fashion," says Lepor...
