# e-bot: mimicking the structure of the "powdery alligator-flag" (Thalia dealbata)

<< Versatile, light-weight materials that are both strong and resilient are crucial for the development of flexible electronics, such as bendable tablets and wearable sensors. Aerogels are good candidates for such applications, but until now, it's been difficult to make them with both properties. Now, researchers report in ACS Nano that mimicking the structure of the "powdery alligator-flag" plant [Thalia dealbata] has enabled them to make a graphene-based aerogel that meets these needs. >>

# s-gst: lastly, they indicate the generality of that

<< Lastly, [AA] indicate the generality of this phenomenon by demonstrating suppression of chaotic oscillations by coupling to a common hyper-chaotic system. These results then indicate the easy controllability of chaotic oscillators by an external chaotic system, thereby suggesting a potent method that may help design control strategies. >>

# s-acad: null results also to be published

<< Translational Behavioral Medicine, a major scientific behavioral medicine journal, now publishes research studies that have null results. >>

<< Some in the scientific community view null results research as a failure because, by its very definition, a null result means what you expected would happen in your study did not happen. >>

<< But Translational Behavioral Medicine (TBM) Editor-in-Chief Suzanne Miller-Halegoua, PhD, disagrees with that assessment. >>

# s-evol: just three traits to explain, by Tereza & John

AA << found that just three traits explained most variation in diversification and species numbers among phyla: the most successful phyla have a skeleton (either internal or external), live on land (instead of in the ocean), and parasitize other organisms. >>

<< Other traits, including those that might seem more dramatic, had surprisingly little impact on diversification and species numbers: evolutionary accomplishments such as having a head, limbs, and complex organ systems for circulation and digestion don't seem to be primary accessories in the evolutionary "dress for success."  >>

<< "Parasitism isn't correlated with any of the other traits, so it seems to have a strong effect on its own," said Wiens [John Wiens]. >>
