Scientists explain TOPPIX like real life gene control
Boyer describes creating a DNA segment that reorders gene expression in E coli to produce an enzyme digesting. The artificial DNA displaces a repressor, allowing the gene to activate. Scientists connect repressor molecules to developmental outcomes in humans, such as hand or nose formation.

New VD Strain Spreading. 4th Resistant Gonorrhea Emerges
The nation reports a pencillin resistant gonorrhea strain first found last February now in 10 states, posing a grim outlook for control. Dr. Paul Wiesner of the CDC warns resistance to many antibiotics could wipe out protection, with spe tinomycin as the only effective drug yet curing 4 of 10 patients. Officials fear rapid resistance growth could negate current defenses and doctors must avoid injudicious spe tinomycin use while penicillin remains the preferred cure in most cases.
