Chewing, or mastication, is thought to impact jawbone structure as bone is continually reconstructed along with alterations in mechanical load. However, the underlying mechanisms are unknown. In a new study, mice fed a hard diet exhibited greater masticatory force, which enhanced growth factors in the osteocytes in the jawbone and enhanced bone formation. This change was predicted by computer simulation, and confirmed by in vivo micro-computed tomography. Thus, jawbone is able to adapt to the mechanical environment to which it is exposed.

Compostable food containers seem like a great idea: They degrade into nutrient-rich organic matter, reducing waste and the need for chemical fertilizers. But much of this packaging relies on per- and polyfluoroalkyl substances (PFAS) to repel water and oil. Now, researchers have shown that PFAS can leach from the containers into compost. However, the potential health effects of applying this material to crops are unknown.

DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine. However, these intriguing structures don't persist long in biological environments because of enzymes called nucleases that degrade DNA. Now, researchers have designed DNA nanostructures that can heal themselves in serum.
