[quick news] eating "sugar" on November 22, 2018 may slow down tumor growth

Eating "sugar" may slow down tumor growth, a British research team said recently that taking monosaccharide mannose alone or in combination with chemotherapy drugs can slow down tumor growth in mice The prospect of this research is considerable, but it still needs to be verified by further research Relevant papers were published online in nature Many tumors experience metabolic changes, showing increased glucose uptake, which raises the question of whether taking different types of sugar can affect tumor growth Kevin Ryan of Cancer Research UK and colleagues studied the effect of Mannose on the growth of tumor cells They report that mannose slows the growth of tumor cells and suggest that mannose may interfere with glucose metabolism Mannose therapy may represent a simple and safe way to target multiple tumors, the researchers said Https://www.nature.com/articles/s41586-018-0729-3 ultra thin porous new materials easily capture carbon dioxide Professor Wang Zhi's team and their collaborators in the school of chemical engineering, Tianjin University have successfully constructed metal induced ordered microporous polymer (MMPs) with ordered microporous structure for the first time, which is used for efficient separation of carbon dioxide and nitrogen Copper or zinc metal ions, organic coupling molecules and short chain polymers are used as structural units MMPs can be coated on commercial basement membrane, which not only has the characteristics of MOFs pore structure, but also overcomes its shortcomings, and has better film-forming property and better stability At the same time, the structure can make carbon dioxide with good affinity with the polymer unit penetrate, while nitrogen with poor affinity is blocked, thus realizing gas separation This study not only helps to alleviate greenhouse gas emissions, but also opens up a new field for gas separation technology The research results were recently published online in nature materials Https://www.nature.com/articles/s41563-018-0221-3 British institutions suggest to the government that Google and Apple should be forced to share map data ODI suggests to the government that "Google, apple, Uber and other technology companies should be forced to share map data with their competitors and public sectors" According to the report released by ODI, this data monopoly hinders innovation in the UK If their data is shared, new technologies like drone delivery services and driverless cars will benefit Geospatial data is an important resource in the digital era If it can be widely shared, it can bring 70 billion to 140 billion extra income to the country Https://www.theverge.com/2018/11/20/18104640/google-apple-uber-mapping-data-share-uk-open-data-institute instagram launched AI tools to combat "zombie powder" instagram is taking action to combat "zombie powder", "brush praise", "brush comments" and other behaviors, and launched new machine learning tools to find and eliminate such "false activities" In order to increase popularity, many users will buy "zombie powder" from a third-party company to brush their praise and comment Such behaviors not only violate instagram's community principles and terms of use, but also bring security risks Once such false concerns, compliments and comments are found, instagram will delete them, send warning messages to users, require users to change their passwords to ensure the security of their accounts, and even restrict users' access to "certain functions" Https://www.dailymail.co.uk/sciencetech/article-6407743/instagram-cracks-make-followers-firm-launches-ai-tools-spot-inauthentic-activity.html new roof equipment can supply power and reduce temperature Scientists at Stanford University have developed a roof top device that can collect solar energy while also releasing infrared radiation from buildings into space, helping to cool buildings, the daily science website reported recently Most of the radiation is reflected back to earth through particles in the atmosphere, but some of it escapes into space, the researchers explained In this way, the temperature of the surface emitting enough infrared radiation will be lower than that of the surrounding area, so as to achieve the purpose of cooling The research team proved that the combined device can provide 24 ℃ solar heating and 29 ℃ radiation cooling at the same time, and the solar absorber can also improve the performance of the radiation cooler by blocking the solar heat https://www.sciencedaily.com/releases/2018/11/181108142418.htm
