Episode notes
Tiny Tractor Beam
- MIT engineers created a chip-based tractor beam for manipulating biological particles like cells.
- This miniature device uses silicon photonics and light to trap particles, offering a smaller and potentially cheaper alternative to traditional optical tweezers.
Crystal Palace Construction
- The Crystal Palace, built in 1851, was constructed remarkably quickly.
- Standardized screw threads, a relatively new innovation at the time, played a key role in its rapid assembly.
Botany's Dark Spots
- Botanists identified 33 "dark spots" globally with potentially thousands of unknown plant species.
- Many of these undiscovered species are at risk of extinction due to habitat loss and inefficient documentation.
