<< It may not happen in our lifetime (..) but "the risk that Earth will get hit in a devastating event one day is very high." >>

# s-phyto: they may selectively kill part of the self

<< Plants adopt different strategies to survive the changing temperatures of their natural environments. This is most evident in temperate regions where forest trees shed their leaves to conserve energy during the cold season. In a new study, a team of plant biologists found that some plants may selectively kill part of their roots to survive under cold weather conditions >>

# 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? >>

# 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. >>
