BEIJING -- Chinese scientists have discovered a nanomaterial that reduces the lead levels in rice, potentially helping improve the quality of rice, and ensuring food safety.Lead in soil can be absorbed by rice roots, seriously affecting rice quality and food safety. This calls for research on how to reduce the migration of lead from soil to rice, to minimize its threat to human health.Nano-hydroxyapatite (nHAP) is a nanomaterial that has been used in the restoration of lead-contaminated water and soil. Researchers from the Institute of Solid State Physics under the Chinese Academy of Sciences used hydroponic experiments to investigate nHAP's potential for reducing the toxicity and mobility of lead in rice.They found that nHAP existing in root cells was beneficial for reducing lead levels and restraining the movement of lead from the roots to shoots. The research was published in the journal "Environmental Science: Nano."The research provides a theoretical basis for environmental nanomaterials inhibiting lead. It also provides technical support for reducing the absorption and transfer of lead in rice. custom braceletsfuck cancer braceletevent wristbandsrubber band bracelets

[Photo/Agencies] The schoolchildren have had their say: A pair of futuristic digital characters will be the mascots for the Tokyo 2020 Olympics and Paralympics. Organizers unveiled the winning designs at a school in Tokyo on Wednesday. A total of 205,755 classes at 16,769 elementary schools took part in selecting three short-listed designs, with their classes casting a single vote. The winning pair, clad in the 'ichimatsu checkered pattern of the Games' official logo, received 109,041 votes. The Tokyo 2020 Olympic and Paralympic Games finally have their mascots, said Ryohei Miyata, head of the mascot selection panel. This means a lot, especially in Japan. I cannot wait to see these two characters coming to life in the stadiums, on the streets and on TV.Organizers say the mascots combine tradition with innovation.
