- A 2013 arXiv paper (1310.4546v1) and two follow-up PDFs explore how altruistic language—beneficial to hearers but costly to speakers—can evolve, offering a formal model relevant to AI alignment and human-machine communication.

- Centauri Dreams posts on Dyson-sphere-powered laser beacons and the “server-sky” concept argue that space-based data centers transmitting information (not power) are more feasible because microwave data links tolerate 90 dB loss versus ~10 dB for power beaming.

- A fingertip-implanted 1 mm × 3 mm parylene-coated neodymium magnet can lift an AA battery and is being upgraded with an untethered coil driver; the group debates ultra-low-power activation schemes such as back-EMF sensing, Hall sensors, or reed switches to create a silent, screen-free “sixth-sense” output channel.

- The implant doubles as a tactile/auditory interface: when the finger is touched to the ear, modulated magnetic pulses become audible, demonstrating a dual-mode human-computer interface that can convey orientation, UV index, or other sensor data as felt pulse trains.

- MIT’s glass 3-D printer (Vimeo + Hackaday) extrudes optically clear molten glass through a heated nozzle, enabling high-resolution transparent structures previously impossible with conventional additive manufacturing.

- A NASA high-voltage engineering workshop PDF provides practical design numbers—vacuum gaps withstand ~3 kV/mm normally and up to 20–40 kV at breakdown—guiding DIY or CubeSat-level high-voltage connector design.

- Scott Alexander’s short story “Five Thousand Years in an Alternate Universe” is recommended for its depiction of a prediction-market-based science funding model in which neutral “consultant scientists” run confirmatory experiments chosen by opposing investor groups.

- Technology Review coverage explains how next-generation telescopes could detect alien light-sails via reflected starlight, offering a concrete SETI observable tied to advanced propulsion engineering.
