Bead-shaped brain cells, self-healing metal, oil-eating sponges — how well are you keeping up with science news?

This week's science headlines are full of surprises: rewritten neuroscience textbooks, self-repairing materials, and biological oil-spill cleanup. Tell us what you think!

1. Researchers say brain cell axons aren't smooth tubes, as textbooks have shown for over a century, but bead-like structures instead. How surprised are you that such a fundamental fact is only being discovered now?
2. Researchers have developed a 'smart' metal coating that activates the moment damage occurs, preventing rust. Would you use such a coating at home, for example on your car or fence?
3. Israeli researchers have developed an oil-eating-bacteria-soaked sponge to clean up ocean oil spills. How much do you trust such biological methods compared to traditional chemical cleanup?
4. Some analysts argue that technology export restrictions — like the ones the US imposed on China — actually strengthen the restricted country in the long run by forcing it to invest in its own research. Which view do you lean toward?
5. North Korea's underground nuclear tests had lasting geological consequences under the test site, discovered only years later. How important do you think it is for science to closely track the long-term environmental effects of military tests?
6. Of the recent science headlines, which fields interest you most? (choose up to 3)
7. András Stipsicz has been asked to lead Hungary's HUN-REN research network on an interim basis, while the network is also being restructured. How important is it to you that a national research institute network runs stably and predictably even during leadership changes?
8. How old are you?
9. Which county do you live in?
10. What size settlement do you live in?
11. How would you describe your living environment?
12. How many people live in your household (including yourself)?
13. What citizenship do you hold?
14. How long have you lived at your current residence?
