Sometimes science gets weird. Sure, it's responsible for every incredible advancement we take for granted today, but there have been, and still are, a few oddballs in the community. From human-animal hybrids to the real-life Frankenstein's pet dog, let's explore some of the strangest scientific experiments ever conducted.

You're listening. You're listening. You're listening.

You're listening to be amazed.

Number 10.

Pig human hybrids.

Until recently, it seemed human-animal hybrids were purely the stuff of science fiction.

But recent developments in genetic engineering are making those sci-fi tales a reality.

In 2016, part-human, part-pig embryos were successfully created by scientists.

The purpose was to create healthy animals that can grow transplantable human organs when needed

to ease the global shortage of organ donors.

To create the chimeras, scientists used an advanced gene editing technique known as CRISPR

to delete the parts of the fetal pig's DNA responsible for developing the specific organ.

Then, human stem cells are inserted into pig fetuses.

Stem cells are genetically blank cells that can adapt to almost any purpose in the body,

depending on the chemical commands they're subject to.

In early stages, when the pig fetuses haven't yet developed their immune systems,

their bodies don't reject the foreign human stem cells.

With the human cells in place, they're able to grow into human organs.

For now, the scientists conducting the study won't let the pigs develop beyond the fetal

stages, but authorities have already raised concerns.

After all, what would the ethical implications be if a modified pig was given a human

brain, and hence more human-like intelligence?
