Modifying Mosquitoes with CRISPR - AMNH SciCafe

- Опубликовано: 29 янв 2017
- CRISPR gene editing is widely used by biologists as the DNA programming tool of choice to alter the genome of organisms and even populations. By modifying the DNA of mosquitoes, we could prevent them from reproducing-potentially eradicating them completely. But is that something we should actually want to see? Join Rockefeller University professor Leslie Vosshall as she demonstrates what is-and what will be-possible.

While we're at editing genes, would it be possible to shift the female mosquitoes' needs from blood to pollen, just as the male mosquitoes?
No. Females feed on blood because this is the protein for their eggs.
My opinion is, we deleted smallpox without worrying about the outcome. We defeated one subset of species of hookworm, we should do the same with this subset of species of mosquitos.
What could possibly go wrong?
Covid 19? Cured with anti malaria drugs
Anyway great talk, what an exciting area of interest!
nice talk
How would it get to other insects i wonder.
Parasites that feed on both species, maybe? Viruses work by injecting RNA or DNA to hijack the host's resources and reproduction facilities, and that material can make its way into the host's permanent genome (some large percentage of human DNA is from this). I think there's some risk of horizontal gene transfer that way. It's probably a tiny risk, but you have to consider it before going through with something like this.
it's a very sensitive subject because killing mosquitoes isn't the solution and it will shift enormously the balance in nature, we need to study all the consequences before doing anything
You just heard that hundreds of thousands of people die a year because of one species of misquito and you want to wait? We can never study all consequences before doing anything because we would be paralyzed, and never do anything. We must act, because that is the only possible solution.
sereminar4 this subject is a big dilemma, if you ask a biologist or ecologist about the consequences of such act, he will tell you surely that the impact is huge and drastic on the environment, specifically on the food chain of the ecosystem and the interacting between mosquitoes and other animals and plants, the key solution here is finding another set of genes, by which we can stop mosquitoes from biting humans without eradicate them entirely, i think it would be a fair solution for us and for the equilibrium of nature
We aren't talking about eradicating all mosquitos, only like 1 species that mainly (specifically) preys on humans. The bats and birds will just have to eat something else, we've certainly caused mass extinctions and ecological catastrophes for worse reasons. (not that it would really probably be as impactful as the oil spill in the gulf of mexico, for example)
Every human intervention in nature is bound to generate disequilibrium. We've been doing it since we originated as species, so you can view the extinction of mosquitoes as something really big and really dangerous or something trivial. The thing is, even if we kill all mosquitoes, people are still going to die for other many (new) reasons.
Incorrect use of scientific method. There are over 1 million species of bugs. Mosquitos cause disease & discomfort. There are many other species to choose from for carnivorous insects. Don't you read a science book?
Is it possible to spread mosquitoes which are immune to malaria and other diseases instead of eradicating the mosquito population?
No. Easier to eradicate via this Darwinian process. The malaria is due to paramecium. Mosquitos still carry other diseases.
Would it be possible to give the females a gene that satisfies their nutritional needs so we are eliminated from their menu and the natural balance is maintained?
Have a video of a scientist looking at a scared little mosquito in the face. Telling it that the game is over… its whole stinking race will be extinct… and somehow the mosquito understands and is looking scared.
Pandemic of the
un-vaccinated remember?
14:10 "efficacious" Rofl, smart people are changing words to sound smarter. The word you were looking for is "effective".
R.B. both have the same definition
And both words are around 500 years old...
Terrible idea
