Prize4Life has a post about the founder of that organization, Avi Kremer, and his fight against ALS. He's asking for $1 donations to the prize foundation, a
non-profit organization that seeks to create breakthroughs in effective ALS/MND (Lou Gehrig's disease) treatments using the leverage of large inducement prizes. Inspired by the success of other inducement prizes, Prize4Life recently launched a $1 Million ALS/MND Biomarker Challenge to stimulate scientific breakthroughs in ALS/MND. The organization will be launching several other multi-million dollar challenges in the near future.
Here's there Dollar4Life site, and you can see portraits of people who are fighting ALS here. Each dollar donated lights up another pixel in the portraits.
