Mosquitoes can be said to be public enemies of the whole people. Wearing short-sleeved shorts in summer will inevitably be bitten by mosquitoes, and often when you come back from the door, your legs are full of bags. In this incident, the news said that the professor cultivated cold-resistant mosquitoes, which can also come out in winter. Let's not talk about whether there are other unconfirmed non-directional mutations in mosquitoes that have mutated this gene. If a large number of mosquitoes with frost resistance are released, it will definitely cause changes in the mosquito gene pool, and it is possible that the overall frost resistance of mosquitoes will gradually increase. Maybe there will be mosquitoes in winter, and mosquitoes are no longer exclusive to summer.
We really can't exclude all useless inventions like this, or useless inventions at this stage. After all, maybe this is the hobby or ambition of other experts. We have no right to prohibit experts from studying these directions, but I think patents and inventions of this level need to be discouraged to a certain extent. For example, some partial patents are not uncommon in our country's patent library, such as mutton kebabs with stinky tofu, artificial fan smog and so on. The richness of imagination and the boldness of innovation are staggering. I dare not say that these patents are useless, but the research direction is somewhat biased, not popular, or difficult to achieve, and even if it is realized, the effect is not significant.
At present, ZTE and Huawei in China are sanctioned by the United States. It can be seen that the patents in some high-tech fields in our country are much worse than those in the United States, otherwise our enterprises would not be hit so hard. I don't think there are many patents, and high-quality and high-level patents are what we need.
