For the sake of their professional health, most scientists feel an instinctive need to stay as far away from these toxic areas as possible. This is truer for some scientists than others. Cosmologists, for instance, seem happy to explore wacky ideas without worrying about the consequences. Fred Hoyle, one of the most famous cosmologists of all, once claimed that seasonal viruses come to Earth from outer space. A lot of people argued with him, but because of his speciality, no one thought any less of him for being a bit eccentric.
Biologists are a different breed.
The experiment itself seemed almost like a stunt. Perhaps this is one reason why no laboratory in the world picked up where Isamu Suda left off. No other biologist repeated his work to verify it, and no one tried adjusting the variables to get better results. In fact the whole field of cryobiology has become extremely cautious since the 1960s. These days, at the annual conferenced sponsored by the Society for Cryobiology, you will find no trace of the bold work that was done three decades ago.
