Genetic tool aims to stem the tide of oyster virus
Initially, a new chip loaded with oyster DNA pieces will identify oysters resistant to the herpes virus, but in the future it may be able to identify oysters with other desirable characteristics, such as faster growth rates.

On GM foods, part 1: Let’s move this unproductive conversation forward
In the first part of a series on genetically modified foods, independent advisor Scott Nichols discusses the simplistic decision behind product labels and the more complex question of what could and should be the outcomes of its use.

Caveat emptor when seeking for EMS solutions
The development of polymerase chain reaction testing to detect the bacteria that cause EMS is important, but confirmation by bioassay of presumptive positives to ensure pathogenicity is a prudent intermediate step.
