There is a kind of mouse in the world that protects humans with its life, but unfortunately many people do not know it
Just as the so-called "street rats everyone shouts and beats"; rats are the number one nemesis of human beings, they reproduce amazingly, carrying hundreds of bacterial viruses, not only spoiling human food will also endanger the health of the human body, but due to the strong environmental adaptability of rats, humans have no feasible plan to deal with rats, although rats are hateful, but not all rats are harmful to humans, such as mice.
The genetic combination of mice is extremely similar to humans, and in many diseases that are difficult for humans to treat, people can find similar traits in mice and use them for research, and genes also determine the occurrence and development of many genetic diseases.
What you may not know is that most mice suffer from genetic diseases, such as melanoma, hereditary anemia, familial obesity, and through the free combination and recombination of genes in inbred mice, their offspring can be used as a tool for genetic analysis, which can be used for the localization of genes and polymorphisms.
In addition, scientists can also use the way to inactivate or miss some specific genes to understand what role a gene plays in an organism, the technology is also called gene knockout, and we often call "genetically modified organisms", in addition to being used in agricultural products, in mice are also the most often used as research.
In terms of drug safety testing, mice are often used as toxicity experiments and drug quantity identification, including teratogenicity, carcinogenicity, genetic mutations, etc. It can be said that behind every drug that people use now, there are thousands of mice who have sacrificed their lives.
In addition, there is a larger "mouse" that is silently protecting humans with its life, which is the African giant cheeked sac rat. African giant-cheeked sacrats, also known as Gambian giant rats, this species of rat can grow up to 1 kg, body length of up to 25 cm, after training, African giant cheeked sacs will be thrown into the dangerous area where landmines may be planted, becoming a "minesweeper".
Mine clearance work is extremely dangerous, people first trained minesweepers to clear mines, canines have more than thirty times the sense of smell of human beings, you can smell the smoke of explosives, but compared with minesweepers, minesweepers are susceptible to external influences due to unstable personality problems, and excessive weight, in the process of mine clearance many minesweepers are sacrificed, and minesweepers do not need to worry about this problem.
Weighing only 1 kilogram, the African giant cheeked sac rat will not explode even if it steps on the mine, and their sense of smell is sensitive, they can smell the explosives across the soil, and when they confirm the location of the mine, they will gently pull away the soil and signal to the staff.
It is understood that an African giant cheeked sac rat can be trained when it grows to 4 weeks, and can be put on the job after 9 months, and the African giant cheek sac rat is extremely efficient, they sweep a tennis court-sized minefield in only half an hour, compared with humans using professional instruments, it takes 4 days, and the African giant cheek sac rat has a long lifespan, usually living to 8 years old.
So far, there have been no incidents of African giant cheeked sacrats dying in the process of mine clearance, and in Cambodia there has even been a "hero rat", the African giant buccal sacrat named Maggawa has found 71 mines and 38 bombs in the past five years, and the area it has cleared has reached 225,000 square meters.
Cambodia says there is still a long way to go in the future of demining, with about 60,000 people killed by landmines and bombs and as many as 25,000 amputated every year since 1979, while the United Nations says it will take at least 1,100 years to get to know all the remnants of the world's mines.
