Hundred Rabbits, a small Canadian collective, documents its life sailing the world while running its technology entirely off-grid, using solar power and low-energy tools. The group shares research on resilient, energy-efficient computing and slow travel from its home base in Canada, drawing fresh interest from readers curious about self-sufficiency, alternative lifestyles and running digital work without relying on grid infrastructure.
- 2RIT Thesis Defense Examines Diffractive Solar Sail Radiation Pressure▼Imaging Science Thesis Defense: Radiation Pressure on a Hybrid Diffractive Solar Sail | Events | RIT
A doctoral candidate at the Rochester Institute of Technology is defending a thesis on radiation pressure acting on a hybrid diffractive solar sail. Diffractive sails are a proposed advance on reflective solar sails, using diffraction to steer a spacecraft without propellant. The defense, listed among RIT's public events, covers how such a sail responds to sunlight and what that means for future solar-sail missions.

The SETI Institute has announced its largest-ever observing campaign with the Allen Telescope Array, a technosignature survey targeting the anti-Solar point on the sky. By staring at the region directly opposite the Sun, astronomers hope to catch signals from alien spacecraft that might be solar-sailing toward Earth, screening themselves against sunlight. The campaign marks a major expansion of the institute's search for extraterrestrial intelligence.

The Cornell Daily Sun has published a column titled 'SOLAR FLARE | Sailing Into Yacht Rock', looking at the smooth, sailing-themed soft rock sound of the late 1970s and early 1980s. The piece appears to be a student commentary or music feature discussing the genre and its appeal, though little detail is available beyond the headline.
- 5Planetary Society shows concept for coilable stacked solar sails▼Coilable Stacked Solar Sails artist's concept
The Planetary Society has released an artist's concept of a coilable stacked solar sail, a lightweight propulsion design in which multiple sails can be compactly coiled for launch and unfurled in space. Solar sails use sunlight pressure for propulsion without fuel, and stacking could allow larger reflective surfaces than current single-sail craft like LightSail.
