Whether you sleep with the fishes, drink like a fish, or have a waterproof — you probably have blood and would like more on occasion. Now you can bleed like a fish (so to speak) with the new artificial blood vessels made from salmon skin collagen at Hokkaido University. The seafood industry there discards about 600 tons of collagen a year, in salmon skin form, and unlike most other collagen sources, there is exceedingly low risk of cross-species viral infection (unlike with cow or pig sources). Previously salmon collagen was not an option since it melts at only 19°C, but new techniques have raised its melting point to 55°C. So if your salmon blood vessels are melting, odds are, so are you.
