# s-evol: Burmese python, mechanisms underlying post-feeding regenerations

<< A research team at the University of Texas at Arlington (..)  has been exploring the genomes of snakes and lizards to answer critical questions about these creatures' evolutionary history >>

<< For instance, how did they develop venom?

How do they regenerate their organs?

And how do evolutionarily-derived variations in genes lead to variations in how organisms look and function? >>

# s-gst: coupled solitons jiggle like molecules

<< The first direct observations of how "molecules of light" can vibrate have been made by >> AA << who have characterized the motions of soliton laser pulses that interact with each other in an optical fibre >>

AA << map the internal motion of a soliton pair molecule [..] revealing different categories of internal pulsations, including vibrationlike and phase drifting dynamics >>

AA results << agree well with numerical predictions and bring insights to the analogy between self-organized states of lights and states of the matter >>

# 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-behav: individuality among Amazon mollies

<< Genetically identical Amazon mollies raised individually and under identical environmental conditions, nevertheless develop different personality types. Additionally, increasing the opportunity for social interactions early in life appears to have no influence of the magnitude of personality variation. >>

AA << team used the Amazon molly, a livebearing Poecilid species. These animals are natural clones, meaning all the offspring of one mother have exactly the same genetic material. >>

# s-brain: all rely on one central function: emulation

<< Our brain's fronto-parietal network is responsible for a range of highly diverse functions, from planning and executing movements to mental rotation, and from spatial attention to working memory. But how can a single network participate in such a wide variety of functions? >>

[AA]  << have recently put forward an original hypothesis — all these cognitive functions rely on one central function: emulation. This function creates an abstract dynamic 'image' of movements, thereby enabling the brain to strengthen its motor skills and construct a precise and lasting representation of them. >>

Acting and thinking — are they the same for our brain?

# e-ai: an intriguing hypothesis: cheating that system will become near impossible

<< Blockchain is an online global  database that anyone with an  internet connection can use  anywhere in the world. Unlike  traditional databases that are  owned by central figures like  banks and governments a  blockchain doesn’t belong to  anyone. And with an entire  network looking after it, cheating  the system by faking documents, transactions and other  information will become near  impossible. >>
