Bats don't rely on gut bacteria the way humans do Right now, there are trillions of bacteria living in your gut, making up about one percent of your body weight. They're supposed to be there—we need them to help us digest food and fight off diseases. The same is true for most mammals; in general, just about every mammal from dogs to dolphins relies on a community of helpful bacteria, called a microbiome, living inside them for health and survival. Many animals have even evolved along with their gut bacteria to better work together, to the point that closely related host species typically share more similar microbiomes. But a new study has identified one group of mammals that seems to buck that trend: bats. A new paper in mSystems reveals that the microbiomes of closely-related bats can be totally different from each other, which suggests that having a community of helpful gut bacteria may not be so important for this already eccentric group of mammals.
New research finds carbon nanotubes show a love/hate relationship with water Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
Study reveals breach of 'dancing' barrier governs crystal growth While crystals have been studied for centuries and are ubiquitous in daily life—they are in our bones, the food we eat and the batteries we use—scientists still don't fully understand how crystals grow or how to efficiently manufacture them. As a result, scientific efforts to improve a wide range of crystalline materials, from self-healing biomaterials to solar panels, have been limited.
