    American media focuses on "portable laboratory" to detect coronavirus: only credit card sized American media said that engineers at the University of Cincinnati in the United States have developed a micro portable laboratory that can be plugged into a mobile phone, and the customized application developed by the university can automatically send test results to doctors The credit card sized lab can diagnose infectious diseases such as coronavirus infection, malaria, AIDS or Lyme disease, as well as countless other health problems such as depression and anxiety The research report was published in the journal micro systems and Nano Engineering, a subsidiary of nature Http:// scientists invented the software robot "sweating" In a study published in science robot, the research team of Cornell University designed a software mechanical grab that can cool down through "sweating" Each mechanical grab contains three "fingers" that can be bent synchronously to grasp the object These fingers are made of hydrogel 3D and store a lot of water The fingers have channels in the substrate that allow the liquid to flow; the surface layer contains small holes When the temperature is low, the stomata are closed When the temperature reaches 30 degrees, the surface hydrogel expands and the stomata expand Its cooling efficiency is 107 watts per kilogram, higher than that of mammals This technology can help robots working for a long time to dissipate heat and avoid overheating Http://digitalpaper.stdaily.com/http_ Div = - 1 neural network technology helps autonomous vehicles identify phantom objects Researchers from the Research Center for Internet Security in Negev, Ben Gurion University, Israel, said that projecting images on the road to form phantom objects can lead to misjudgment and sudden braking of semi autonomous or fully autonomous driving vehicles, thus endangering the lives of drivers and passengers in the vehicles The neural network technology they are working on will solve the problem that autonomous cars cannot recognize phantom objects Http://digitalpaper.stdaily.com/http_ HTM? Div = - 1 Scientists have found in the glaciers of the Qinghai Tibet Plateau in China that the ancient virus never seen before, the glaciers of the Qinghai Tibet Plateau block millions of micro organisms per square inch In 2020, researchers from the United States and China found evidence that there are ancient viruses in glacier ice, including 28 new virus genera The results were published on the preprint server biorxiv Records of ancient microbes, such as those found in glacial ice, allow scientists to understand the evolution and climate history of the earth Scott O Rogers, a professor at Bowling Green State University in the United States, put forward a more frightening view: "the risk of being wrapped in ice is real, and as the global ice melts, the risk of the release of pathogenic microorganisms increases." Http://news.bioon.com/article/6750215.html is air also toxic? The novel coronavirus pneumonia is also a low risk factor in the aerosol The experts said that the probability of being caught in the aerosol is lower than that in a car accident Recently, a leading group of epidemic prevention and control work in Shanghai revealed that a new epidemic of crown pneumonia was mainly caused by direct transmission, aerosol transmission and contact transmission Experts from the China Center for Disease Control and Prevention said that the new coronavirus can only be spread by aerosols under some special conditions, such as professional medical operations such as clinical tracheal intubation If it is in the normal clinical care and general working and living conditions, it is enough to protect the general public without infection to take the correct protective measures of wearing masks http://
