Beata Halassy , a virologist at the University of Zagreb in Croatia , made herself a test subject.

She injected herself with two types of viruses that she cultivated in a lab.

Her homegrown remedy caused her tumour to shrink, enabling surgeons to remove it.

Halassy joins a long line of researchers who have tested medical theories on themselves.

Halassy and her co-authors wrote that the study did not undergo a review by an ethics committee because it involved self-experimentation.

Opponents of the practice argue that publicizing cases like Halassy ’s risks encouraging less qualified patients to self experiment in more dangerous ways.

“Not every experiment is research,” Charo said.

Space Forge wants to send satellites equipped with tiny clean rooms into space, where they’ll grow semiconductor crystals before transporting them safely back to Earth .

Manufacturing semiconductors in space has the potential to provide efficiencies that could create superior versions of military tools such as radar.

Space Forge has piqued the interest of the 1 billion ($ 1bn ) NATO Innovation Fund ( NIF ).

The NIF is a defense-focused version of the World Bank .

The fund acts as a conduit to link European defense ministries and startups.

One billion euros is not enough to fix Europe , a region whose issues are a mix of strategic and economic.

In theory, the NIF will become a funding model that’s self-sustaining for NATO innovation priorities.
