What gives us color now may give rise to our cyborg future.
- Eumelanin is a mildly conductive type of melanin that produces dark pigmentation in hair, eyes, and skin.
- Researchers have just found a way to boost its conductivity without adding foreign materials.
- Eulemanin may be useable as a coating for implanted devices the body won't reject.
A new method of growing mini-brains produces some startling results.
- Researchers find a new and inexpensive way to keep organoids growing for a year.
- Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
- The mini-brains took control of muscles connected to the spinal cords.
Using a new process, a mini-brain develops retinal cells.
- Mini-brains, or "neural organoids," are at the cutting edge of medical research.
- This is the first one that's started developing eyes.
- Stem cells are key to the growing of organoids of various body parts.
As costs go down and the benefits become more clear, can we afford not to eat lab-grown meat?
- Just a few years ago, the price of a lab-grown hamburger had five figures.
- Today, that price has gone down to just $11.
- Even if it's cheap, tastes the same, and preserves the environment, will people actually eat meat grown in a lab?
