  • 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.

Mini-brains attach to spinal cord and twitch muscles

A new method of growing mini-brains produces some startling results.

(Lancaster, et al)
  • 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.

Brazilian scientists produce mini-brains with eyes

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.

Lab-grown meat's steady march to your plate

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?
