Technology | WaveCel
Interesting engineered structure to provide protection from linear and rotational impacts, as an alternative to traditional EPS foam helmets. Seems to use a slipping/buckling triangle design? I wonder what kinds of improvements there would be using a smaller microstructure?

Nitrogen fixation in a landrace of maize is supported by a mucilage-associated diazotrophic microbiota
Corn/maize variant that doesn't need fertilizer in poor soil because it has weird aerial root structure actively secreting goop that support nitrogen fixation bacteria, so in theory easier/more sustainable agriculture without fertilizer, but the thing is a bit more tree-like and takes 2-3x as long to grow ears. Still neat though.

Idea is if you have large enough structures (booms), then you can do some interesting attitude control and propulsion tricks

Self-Deployed Space or Planetary Habitats and Extremely Large Structures
NIAC phase 1 results. NRO research related as well for deployable space telescopes. Rigidized UV cured polymer thin film bubbles for space applications. Possible flat primary mirrors/solar sails, but if they are making spheres, making curved mirror segments should be doable. If you use 6 stabilizing hoops as cut lines, can get 6 sphere segments without much waste (waste could be repurposed as additional mirror segments)

In-drop capillary spooling of spider capture thread inspires hybrid fibers with mixed solid–liquid mechanical properties
So spider silk has a watery glue that also functions as a local spool to pull in loose silk thread. Now that has been emulated with oil droplets and plastic filament.

Called Heliofloat, it sounds like a variation of a classical PSP platform, using semi-flexible barrel/cylinder side walls to absorb some wave motion. Using a marine concrete PSP sounds more durable, though at greater weight/cost?
