but it will require carbon emissions to be cut by 45% by 2030. to help get us there i have proposed a climate solidarity pact in which all big emitters would make extra efforts to cut emissions and wealthier countries supporting emerging economies to do so. scientists have created a synthetic human embryo using no egg or sperm. they could be used for research. they re described as embryo models rather than real embryos. researchers from university of cambridge and california institute of technology behind it. this hasn t been published in a scientificjournal yet. and obviously all this all raises big ethical questions. scientists say they have created synthetic human embryos using stem cells, bypassing the need for spurn or eggs.
we followed them around and came up with, no solid conclusions really about the origins of covid i9 and the who was supposed to have a further inquiry in supposed to be a new team coming to china and i don t know whatever i m to the team being put together and there was a report in the scientific journal put together and there was a report in the scientificjournal saying that the who had effectively shelved this and since then, without the who saying no, we have not given up on the origins of covid i9 but where is the origins of covid i9 but where is the team, the new team of scientists looking into this? so questions over that investigation but still no scientific evidence pointing to a lab leak. which brings us to the other theory that scientists say is more likely. the natural origin theory that covid originated from a natural spill over from infected animals. supporters of that theory say covid emerged in bats, thenjumped to humans, most likely through another animal.
of dinosaur evolution. laura foster, bbc news, at the natural history museum in london. it isa it is a fascinating story, let s explore it a bit more with the doctor we just saw in the report, research fellow at the natural history museum and who named and described the dinosaur in a scientificjournal. first of all, it is fascinating there should be a filing error like this, explain more about what happened. goad filing error like this, explain more about what happened. good morning. as i said in about what happened. good morning. as i said in the about what happened. good morning. as i said in the report about what happened. good morning. as i said in the report you about what happened. good morning. as i said in the report you just - as i said in the report you just showed, the museum s collections are really fast. this material was actually discovered back in the 50s and had been worked on a bit, someone had written part of their phd thesis on this material but it had neverfor
causing covid 19. the study published in a scientificjournal found that the molecule produced by the pit viper reduced the virus s ability to multiply in monkey cells by seventy five percent. they hope to test the substance in human cells at some stage but gave no timeline. as you can see, we as you can see, we were as you can see, we were able to see that the peptides not only inhibited the development of the virus, inside the cell, but we are also able to see here that it was able to inhibit one of the proteins that is very important for the development of the virus. and the propagation of new viruses. the environmental campaigner, greta thunberg, says she will only attend the un climate change conference in glasgow later this year, if the event is safe and democratic . for her, that means ensuring participants from poorer countries are fully vaccinated and able to travel to take part. 0ur environment correspondent kevin keane reports
