  1. California’s Prop 13 has pushed a record share of home transfers into inheritance—about 18% last year. That makes inheriting a house a major path into homeownership and reduces normal market turnover.
  2. Data centers suddenly switching to backup power can cause rapid drops in electricity demand that threaten grid stability, and operators worry that larger simultaneous disconnects could do serious damage.
  3. Solar is gaining both technological and political momentum—efficiency records and manufacturing are increasingly centered in China while solar finds new allies in U.S. political circles—and at the same time U.S. nuclear safety rules were substantially pared back in a recent rewrite.

  1. 3D printing is becoming a game changer in manufacturing, with companies like Lego now able to mass-produce 3D-printed parts, improving design options.
  2. The average age of first-time homebuyers is often reported to be rising, but some data suggests it might actually be declining, highlighting issues with survey methods.
  3. Old technologies, like the filings coherer used in early radios, were simple to implement but led to better designs as the technology advanced over time.

  1. Airborne microplastics are a serious health concern. They're found in homes and car cabins, and people may be inhaling a lot more of them than previously thought.
  2. Spinlaunch is developing a new way to launch satellites using a giant centrifuge. This could cut costs and increase launch frequency compared to traditional rockets.
  3. The U.S. car industry has not collapsed but has moved production out of traditional hubs like Detroit. Job growth happened in other parts of the country, despite the perception of decline.

  1. A tiny electric motor was created by William McLellan, inspired by Richard Feynman's ideas on miniaturization. It opened the door to the world of nanotechnology, despite having no practical use.
  2. California is easing environmental rules under the California Environmental Quality Act (CEQA), making it easier to build new housing. This change aims to address the state's housing crisis and high costs.
  3. Volvo is leading the electric truck market with nearly half the market share in Europe and North America. They delivered their 5,000th electric semi truck, showing strong growth in this sector.

  1. Commercial fusion energy is making progress with a new reactor that could generate power for many homes and create jobs.
  2. Boom Technology secured $100 million to develop a supersonic airliner, but its future remains uncertain due to challenges in airplane engine development.
  3. There's growing interest in using airships for cargo transport, as they can be more efficient than ships and planes for certain distances.
