 The **stray dogs** now have a gene pool that differs markedly from that of dogs living anywhere else in the world. Although these animals are descendants of pets left behind at the time of the accident, continuous radiation exposure and isolation have resulted in the emergence of a genetically unique population. In the wild, animals born with severe physical mutations (such as two heads or deformed limbs) almost never survive to adulthood and are therefore unable to reproduce. Those living in the zone today are the //‘gene pool of the survivors’// : subtle molecular changes that help them survive in the face of an invisible threat.  The **stray dogs** now have a gene pool that differs markedly from that of dogs living anywhere else in the world.

-DNA tests have shown that the dogs’ genetic makeup has evolved in such a way that their immune systems and cell division processes are more resistant to radiation-induced cancer. Similarly to the frogs mentioned earlier, some researchers hypothesise that darker fur may offer an advantage in terms of radiation protection, although this has not yet been proven as conclusively in dogs as it has in amphibians.+DNA tests have shown that the dogs’ genetic makeup has evolved in such a way that their immune systems and cell division processes are more resistant to radiation-induced cancer. Similar to the frogs mentioned earlier, some researchers hypothesise that darker fur may offer an advantage in terms of radiation protection, although this has not yet been proven as conclusively in dogs as it has in amphibians.
  
 These changes are not beneficial for all species. Many **birds** (such as the sooty swift) have been observed to have smaller brain sizes, more frequent tumours and discolouration of the plumage (//partial albinism//), which is a sign of genetic damage.  These changes are not beneficial for all species.

 In 2020, researchers sent one such fungal species, **Cladosporium sphaerospermum** to the **International Space Station**(//ISS//) to investigate whether the fungus could be used for radiation protection in space.   In 2020, researchers sent one such fungal species, **Cladosporium sphaerospermum** to the **International Space Station**(//ISS//) to investigate whether the fungus could be used for radiation protection in space.  
  
-A Petri dish was used for the experiment, with only one half coated with the fungus and the other left empty. Radiation detectors (Geiger counters) were placed beneath the dish to compare the amount of radiation that passed through. A layer of fungus just 2 millimetres thick was able to absorb around 2 per cent of cosmic radiation. This may seem like a small amount at first glance, but the researchers calculated that a //‘living wall’// would be sufficient to block a significant proportion of the radiation on Mars. +A Petri dish was used for the experiment, with only one half coated with the fungus and the other left empty.

 The greatest advantage of the fungus over conventional materials (such as lead or aluminium) is that it is alive and reproduces. If the shield is damaged, or if more protection is needed, the fungus simply needs to be //‘fed’// and it will regenerate itself.  The greatest advantage of the fungus over conventional materials (such as lead or aluminium) is that it is alive and reproduces.

 According to long-term plans, cavities built into the walls of Martian bases would be filled with this fungus, so that settlers would not need to transport radiation shields weighing several tonnes from Earth; it would be enough to take a small sample and //‘grow’// the protection on site. Interestingly, the fungus grew even faster in the microgravity conditions of the ISS than it did on Earth, making it even more suitable for use in space. According to long-term plans, cavities built into the walls of Martian bases would be filled with this fungus, so that settlers would not need to transport radiation shields weighing several tonnes from Earth; it would be enough to take a small sample and //‘grow’// the protection on site.
