I usually tend to downplay worries about research in genetics, but I was quite concerned after reading “Expanding the genetic code” (SN: 4/2/05, p. 222). The researchers surely have plans to keep whatever they create contained. But adding a fifth base to the DNA of bacteria with a genetic mutation rate 10,000 times that of […]

The direct approach “An Exploitable Mutation: Defect might make some lung cancers treatable” (SN: 9/11/04, p. 164: An Exploitable Mutation: Defect might make some lung cancers treatable) may have missed a “magic bullet” that would be effective against many forms of cancer. The researchers concentrate on a drug that blocks a mutated form of the […]
