...radio waves. "Nobody knows the consequences of using cell phones from childhood and having radio waves reaching far into the brain," notes Dr. Leif Salford, a Swedish neurosurgeon who has found evidence that cell-phone radiation may weaken the brain's protection against potentially harmful substances in the bloodstream. Salford calls widespread cell-phone use "the world's largest biological experiment ever." He adds, "It would be sad if people found out 20 years from now that they have diseases...
...colleagues have launched a project to unravel exactly what--at the genetic level--makes some people benefit from drugs and others not. They suspect that one major factor is a class of proteins called membrane transporters. These proteins act as molecular gatekeepers, deciding which foreign substances in the bloodstream will be taken into and which rejected by individual cells. If, for example, people lack the gene for an inactivating enzyme, says Herskowitz, "a standard dose of a drug will be more potent. If they have an extra copy of the gene, a standard dose will be inadequate...
...opposite end of the technology scale, Eldrid Sequeira, a Utah State University graduate student, is designing microscopic "submarines"--drug-bearing capsules that someday could be propelled through the bloodstream by bacteria to attack disease. Looking even further ahead for alternative means of driving these tiny craft, he is considering building biomotors 100 billionths of a meter wide that would use only the bacteria's hairlike, propelling flagella to move ahead...
...that OxyContin sales increased 95% in one year, generating $600 million in sales for Purdue Pharma. Indeed, the drug, introduced in 1995, has been hailed as a miracle; it eases chronic pain because its dissolvable coating allows a measured dose of the opiate oxycodone to be released into the bloodstream (see PERSONAL TIME: YOUR HEALTH). However, abusers quickly found that by smashing the pills, they can get all the drug's potency in a rush of euphoria...
...each other's harvest"? I see them in her poems that breathe women in a blaze of upsweeps and backyards and ballads, in her children dancing between urine and violets, in her singing to us between the sleeping and the waking. And as she entered into our 21st century bloodstream, paddling a river of risks, she became the color of bells, set sail on the wind and sailed home. Said hello to our own goodbyes...
