Can you put gooey aliens in the microwave to keep them warm?

The science of aliens is very bizarre, we do not comprehend their cell-structure. It could appear to be gooey on the outside and have a crystalline structure like that of a diamond. Or vice versa, there have been many breakthroughs in the field regarding aliens and microwaves, and one experiment you can try at home is putting a peep in the microwave, some aliens may revert back to being corn syrup, but some aliens may not react as well to the waves, it all depends on the density, and molecular structure of said alien. With our current understanding of this science we cannot give a definitive answer, but Science Fiction leads us to believe that breakthroughs in the next 10 or 20 years may lead to a definitive answer. In conclusion, we cannot say for sure, all we can say for sure is that we can put them in toasters, because the science to conduction v. aliens is a lot simpler than microwave v. aliens.
