Facebook founder Mark Zuckerberg and his wife Priscilla Chan have made an incredible pledge of $US3 billion, that'll go towards a plan to "cure, prevent or manage all disease without our children's lifetime".
The couple hosted a 'Facebook Live' event from San Francisco, to make the 'Chan Zuckerberg Initiative' announcement this morning.
Zuckerberg said their goal is to cure all disease, or at least turn catastrophic illnesses from terminal to manageable or preventable, within their daughter Max's lifetime.
Zuckerberg and Chan welcomed Max into the world last year.
Chan, a pediatrician, fought back tears at time, as she explained their goal of bringing together innovative scientists and engineers to build transformational tools that unlock a new era of accelerated progress in science and health.
"We're at the limit of what we understand about the human body, science and disease," she said.
"We want to push back that boundary, by investing in science today we hope to build a future in which all children can live long and rewarding lives."
"For this initiate, we'll be investing more than $3 billion over the next decade to achieve our collective mission."
Investments will include a bioscience research centre, and plans for a chip to diagnose diseases, continuous blood stream monitoring and a map of cell types in body.
Zuckerberg explained a letter the couple had written for baby Max when she was born, describing the hope she gave them for the future.
"Priscilla's a doctor. I'm an engineer. I think that that hope is part of the engineering mindset. It's that belief you can take any system and make it much better than it is today," he said.
"Whether it's code, government, biology - you can make it much much better than it is today."
"It's an area where we can all do something really important together. This is a big goal."
Other guests included Microsoft billionaire Bill Gates and neuroscience and genetics expert Dr Cori Bargmann.
Almost 3,000,000 people worldwide watched the announcement live.
