các nhà khoa học china tìm ra cách làm cốc nhựa từ... tinh dịch cá hồi :D
Scientists have discovered a wholly novel use for semen (tinh dịch) — if you can stomach it.
The promising substance was created by extracting strands of DNA from the sperm of salmon — though the stuff could come from just about any living thing — and dissolving the genetic matter in water with ionomers, a type of polymer commonly found in adhesives (chất kết dính), to produce a gel that’s pliable (dễ uốn, nặn) enough to be molded into various forms. The material is then freeze-dried to set the shape.
Their experimentation (thử nghiệm) led to the creation of a rumpled-looking mug, as well as puzzle (mảnh ghép xếp hình) pieces, all made of what they call “DNA-based plastic.”
Both DNA and plastics are made of polymers, which may be naturally occurring or synthetic — the former abundantly available in plants, animals and bacteria, and the latter relying on petroleum oil, a k a fossil fuels.
