What does it take to bring back an extinct animal?

We hear from scientists who push the boundaries of creation, whether that's building wild and wacky snack flavours (successfully) or cloning extinct tropical frogs (unsuccessfully … so far).

And since President Donald Trump retook office, the state of health and science research in the US has been precarious for many who work in those areas.

But there is a silver lining. Other countries such as Australia are implementing programs to recruit US researchers looking to relocate.
