[quick news] December 3, 2018 new research reveals the immune escape mechanism of "superbacteria"

The new study reveals the immune escape mechanism of superbacteria According to an international research team led by Max Planck Institute for colloids and interfaces in Germany, they found a previously unknown protein on methicillin-resistant Staphylococcus aureus (MRSA) and named it tarp The protein acts like a cloak of invisibility, keeping methicillin-resistant Staphylococcus aureus from being detected by the human immune system and preventing the immune system from producing antibodies against the bacteria, the researchers said The findings provide a new target for the treatment of bacterial infection in the future Relevant research results are published in the British journal Nature Https://www.mpg.de/12545371/mrsa-bacteria-staphylococus-immune-system the latest research found that mobile phones are seven times more dirty than toilet seats Researchers use handheld devices to extract samples from smart phones to detect the distribution of active microorganisms on mobile phones, and compare the detection results of bacteria on mobile phones with toilet seats The results showed that 220 bacteria were detected in each toilet seat, but 1479 bacteria were detected in each cell phone A survey of office workers found that 40% of them would take their mobile phones to the bathroom in the workplace, but only 20% would clean them after going to the bathroom Before the relevant personnel to mobile phone inspection found that some of the mobile phone bacteria exceeded the standard, and may even make the owner of the mobile phone feel serious stomach discomfort Https://www.dailymail.co.uk/sciencetech/article-6447979/mobile-phones-seven-times-dirtier-toolet-sets-finds-new-study.html ultramicroscopic observation of lithium ion migration in double graphene by scientists from Max Planck Institute for solid state research and Ulm University ）It was found that the performance of lithium ion in the process of electrochemical charge and discharge showed by atomic resolution, which proved the reversible lithium ion absorption of double graphene in a single nano battery Experiments show that when the voltage is applied to the nanocell, lithium ions migrate from the electrolyte drop to the gap of graphene double layer and accumulate there; when the potential difference is removed, the accumulated lithium dissolves and migrates back to the electrolyte drop At the atomic level, this process is difficult to observe in situ According to relevant researchers, ultramicroscopy provides a unique way to understand the nano battery It is a huge scientific challenge to observe the diffusion of light elements such as lithium in graphene interlayer, which can not be done by traditional transmission electron microscopy (TEM) Https://www.nature.com/articles/s41586-018-0754-2 deputy director of Higher Education Department of Ministry of Education According to the 9th Xinhua Education Forum, there is no doubt that one of the hot spots of this year's education work is to attach importance to and revitalize the undergraduate course The next step is to launch a three-level professional certification system, namely "guarantee the qualification, improve the level and pursue the excellence" The three-level professional certification is also an impetus for colleges and universities Fan Hailin said that at present, a prominent problem in China's colleges and universities is that they attach great importance to scientific research and neglect teaching, and the lack of leadership energy, teachers' energy, students' energy and resource condition allocation is widespread Talking about how to revitalize the undergraduate education in an all-round way, fan Hailin said that we should first rectify the undergraduate teaching order by thundering and iron discipline Http://www.chinanews.com/gn/2018/11-30/8689753.shtml Microsoft has announced a new $480 million contract for the US Army to develop smart glasses for soldier training, which will use Microsoft's hybrid reality (MR) smart glasses hololens to train soldiers The $480 million will be spent on the military's integrated vision enhancement system (IVAS) program, which will require Microsoft to develop hololens prototype equipment to provide "lethality, mobility and situational awareness" training for U.S soldiers, and is expected to launch the finished product in the army by the end of 2020 https://comicbook.com/gaming/2018/12/02/microsoft-xbox-hololens-us-army-480-million-contract/
