Carp aquaculture in Neolithic China dating back 8,000 years

Researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.

Welcome indoors, solar cells

Scientists have developed organic solar cells optimized to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.

Hiding in plain sight

(Washington University in St. Louis) Early rice growers unwittingly gave barnyard grass a big hand, helping to give root to a rice imitator that is now considered one of the world’s worst agricultural weeds. The new research from biologist Kenneth Olsen in Arts & Sciences is published this week in Nature Ecology & Evolution.

New study shows common carp aquaculture in Neolithic China dating back 8,000 years

(Max Planck Institute for the Science of Human History) In a recent study, an international team of researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.
