Hijacking sperm cells to create little robots might seem far out, but that's exactly what researchers from the Dresden Institute for Integrative Nanosciences have done. Their "spermbots" consist of live sperm cells in little tubes, that can be magnetically controlled to move in a desired direction until they reach their destination and do their job – they're currently robust enough to even guide a specific sperm cell to an egg cell. The scientists hope that further development will allow the technology to offer a viable alternative to parents trying to have a child through in-vitro fertilization. When perfected, the spermbots could also be used as a safe means for drug delivery and gene manipulation.
According to many people, meat and leather are an ethical and environmental nightmare, causing misery to billions of animals and wreaking havoc on the planet’s ecosystems. While mankind may not turn entirely vegan in the next generation, a more humane and cleaner type of leather could become available in the near future (and meat a few years later) thanks to the development of an in-vitro version of the material being developed by Modern Meadow.
