CODE BREAKER -- YOUNG READERS EDITIONWhen Jennifer Doudna was a sixth grader in Hilo, Hawaii, she came home from school one afternoon and found a book on her bed. It was The Double Helix, James Watson's account of how he and Francis Crick had discovered the structure of DNA, the spiral staircase molecule that carries the genetic instruction code for all forms of life. This book guided Jennifer Doudna to focus her studies not on DNA, but on what seemed to take a backseat in biochemistry:

My dogs love plush chew toys, and this one was definitely a hit. My dog really enjoyed it, especially the squeaker, and the rope was his favorite part. It is a super cute toy with vibrant colors and a variety of interactive features, including a cotton rope, different textures, crinkle paper, and a built in squeaker, which kept him engaged. This toy is great for small to medium sized dogs. However, for larger dogs or strong chewers, it probably will not last very long. My dog had it for only a few days before he started tearing up the rope. For the price, I feel it is reasonably priced and comparable to other toys of similar quality. It works well for games like fetch or tug-of-war, and I also like that it is machine washable. Once it gets dirty, you can simply toss it in the wash, which is very convenient. Overall, it is a fun and interactive toy, just not ideal for aggressive chewers.
