China's Missing 'Bat Woman' with Secrets of Wuhan Virus

By -
There were also questions about her absence since December last year when the virus began spreading in Wuhan and then the rest of China and the world.   A leading Chinese virologist from the Wuhan Institute of Virology (WIV), whose mysterious disappearance sparked speculation about the deadly novel coronavirus emanating from the laboratory, has denied reports of her defection to West with the secrets about the COVID-19. Shi Zhengli, known as the "Bat Woman" for her passionate research about bats and the viruses associated with them, refuted rumours of her defection on her Chinese social media WeChat account, the state-run media here reported on Saturday.  Denying "rumours" of "defecting to the West", Shi on her WeChat account wrote, "Everything is alright for my family and me, dear friends!" She also posted nine photos of her recent life, the Global Times reported. In the post, Shi, reported to be the Director of the WIV, said,...

'Plant Lamp' Draws Electricity from Soil.

Inspired by real and immediate problems in remote areas of the country, researchers at Peru’s Universidad de Ingeniería y Tecnología (UTEC) have developed a remarkable piece of technology — a low-cost LED lamp that uses plants and soil as its batteries. The delightfully named Plantalámpara — or “plant lamp” — technically draws its power from microorganisms in the soil that are released by plants as they grow. By way of an energy producing mesh buried beneath the surface, the system can generate enough power to supply two hours of light per day, per lamp. “We put the plant and soil into a wooden plant pot together with a previously established and properly protected irrigation system,” says Elmer Ramirez, professor of Energy and Power Engineering, on UTEC’s   project page . “Then inside the pot we place the energy generation system that we created which stores soil and electrodes capable of converting plant nutrients into electric energy.” The plant lamp system was ...

China's Tiangong-1 space station will crash to Earth within weeks

Experts say it is impossible to plot where module will re-enter the atmosphere, but the chance is higher in parts of Europe, US, Australia and New Zealand. China’s first space station is expected to come crashing down to Earth within weeks, but scientists have not been able to predict where the 8.5-tonne module will hit. The US-funded  Aerospace Corporation  estimates Tiangong-1 will re-enter the atmosphere during the first week of April, give or take a week. The European Space Agency says the module will come down  between 24 March and 19 April . In 2016  China  admitted it had lost control of Tiangong-1 and would be unable to perform a controlled re-entry. The statement from Aerospace said there was “a chance that a small amount of debris” from the module will survive re-entry and hit the Earth. “If this should happen, any surviving debris would fall within a region that is a few hundred kilometres in size,” said Aerospace, a research organisa...
