Carbon dioxide makes fresh water "sour." scientists at Ruhr University in Bohong, Germany found that as the partial pressure of carbon dioxide increases, some freshwater ecosystems become more acidic Laboratory studies have also shown that an increase in the CO2 partial pressure of freshwater can have an adverse effect on at least one key species, making them unable to perceive and protect themselves from predators These findings suggest that increasing levels of carbon dioxide may have a wide range of impacts on freshwater ecosystems Current biology http:// (17) 31655-x gene editing control gender will become a reality Scientists at the University of California, Davis, have created a bull that will only have male offspring: either a normal calf, or a calf that not only has two X chromosomes, but also carries the SRY gene that determines the male, with no conventional cow at all This is of great value to beef farmers, who are bigger, grow faster and produce far more steaks Beef is already the most valuable agricultural product in the United States MIT Technology Review https:// first potential therapy for Middle East respiratory syndrome phase 1 clinical safety SAB The results of phase 1 clinical trial of anti mers immunotherapy (sab-301) funded by National Institutes of Health (NIH) of biotherapeutics showed safety This is the first study to show the potential therapeutic safety of mers To produce sab-301, scientists inoculated transgenic cattle with mers antigen provided by Novavax Soon the cattle produced a large number of complete human antibodies to fight the virus After bovine plasma was collected in a similar way to human plasma, the antibody was purified to produce sab-301 National Institutes of health https:// the investigation results of sexual harassment case of Professor Florian Jaeger of University of Rochester in the United States have been controversial In early December 2017, nine researchers (including eight in-service or former members of the college and one doctoral student) filed a lawsuit in the federal court, claiming that President Joel Seligman and Provost Robert Clark had failed to perform their duties in the investigation of sexual harassment complaints related to Professor Jaeger To this end, the school introduced an independent third-party investigation into Jaeger's case On January 12, the results of the investigation were released, saying that the school did not neglect their duties, and denied that the school had retaliated against the teachers and students who reported and prosecuted On the same day, President Seligman announced his resignation before the results of the investigation were released Nature https://w w w.nature.com/articles/d41586-018-00422-w scientists found traces of amino acids and liquid water on ancient meteorites a few days ago, a joint team of NASA and the Open University of England found amino acids and liquid water necessary for life on two ancient meteorites that fell on the earth 20 years ago, which is also the same as NASA's discovery in NASA's in recent years The data collected by the Dawn spacecraft are corroborated The two 4.5-billion-year-old meteorites came from the asteroid belt between the orbits of Mars and Jupiter and landed on earth 20 years ago, but the technology at that time could not detect the presence of amino acids Express https://
