A gene that allows ticks to produce an antifreeze protein to resist frostbite and lower the freezing point of blood. The ticks have a protein called IAFGP that is triggered during
winter months, which protects them from the
cold. Mice that were injected with the protein were able to not get frostbite at subzero temperatures. They then genetically engineered the mice and breed them to have babies with the gene and they produced the antifreeze protein, IAFGP. The mice resists frostbite. One
day, some humans could genetically
engineer themselves with the antifreeze tick gene. That way, there's no more frostbite at subzero temperatures(below 32 degrees Fahrenheit, 0 degrees Celsius) until much lower temperatures(like 5 degrees Fahrenheit, -15 degrees Celsius or
something). Eventually, the technology will be affordable to all.
