The covid vaccine was used on apes at San Diego zoo. In the start of 2021 four orangutans and five bonobos became the first great apes at a US zoo to recieve the vaccine for covid. An outbreak in that zoo have caused some panic amog the staff after the virus had spread to the animals, it is suspected that they got infected from a asymptomatic zookeeper. Eight gorillas tested positive with minor symptoms like for example a runny nose or coughs. For now the great apes had recovered but it is still concerning as some experts said that it could even wipe out populations of chimpanzees, gorillas and orangutans because of their genetic proximity to humans.  It is very worrying that the virus is now spreading among animals. Because of that the zookepers and the tourists have been following strict social-distancing rules around the animals. A lot of sientists from the US and from Russia are now working on a vaccine for this problem, but who knows how long it will take them and its sad...

Hummingbirds are easily recognisable by the sound that they make but the cause of the sound has been a mystery for a really long time. That's why scientists started reaserching the way they produce the sound. They have found out that the answer lies in the aerodynamic forces, and hence pressure changes produced as the wings move. They executed many experiments and tests to get this information for example they measured the lift and drag forces produced by the flapping of the wings. I think that it's great that we start looking more into the animal world because it's really interesting and we can find out interesting facts like this. I would have never thought that the sound is actually produced with their wings. I really enjoy reading reaserches on various animals because I think that their world is so fascinating and we know very little for example about the underwater world or even the animals that live with us on the land. https://www.theguardian.com/science/2021/mar/16/...
