Recombinant Spidroins Fully Replicate Primary Mechanical Properties of Natural Spider Silk - Biomacromolecules (ACS Publications)
So they got bacteria to build silk proteins with are almost twice as long as real spider silk proteins, thus the doubled protein is now a near match in performance to true spider silk fiber (true spider silk fiber benefits from good protein design and spinner design though). They seem to think it should be possible to use the fusing method to build even longer proteins to up the strength.

Octopus-Inspired Smart Adhesive Pads for Transfer Printing of Semiconducting Nan...
Interesting material, where heating it causes micropore suction cups to open up so it sticks when slapped onto something, but the pores close when cold. Reusable glue of a sorts?

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.

PROJECT FALCON
Concept for an electric ornithopter backpack airplane. Hrm, I wonder if a turbine powerplant might work here, if the turbine can switch between shaft power mode for electricity generation, and gas jet mode for flight where the wings are fixed like a glider to have more conventional flight like a motorized glider.
