World Solve

Diet and exercise advice hasn't solved the obesity epidemic, and the biological reasons weight loss is so hard to sustain remain only partly understood. A deeper understanding could lead to treatments that actually last.

Some people reach old age with sharp minds and healthy bodies, while others decline much earlier, and genetics only explains part of it. Understanding this gap could extend healthy years of life for far more people.

Some cancers are caught early and treated successfully, while others are found too late simply because no cheap, accurate screening exists for them. Broader early detection could save far more lives than treatment breakthroughs alone.

Methane is a far more potent greenhouse gas than carbon dioxide in the short term, and much of it leaks unnoticed from pipelines and wells. Better detection and faster repairs could meaningfully slow near-term warming.

Millions of tons of plastic enter the ocean every year, and cleanup efforts remove only a small fraction of it. Without cutting the source and scaling removal, marine ecosystems will keep absorbing the damage.

Machine translation is fast and often accurate, but it still misses jokes, idioms, and cultural context that change meaning entirely. Real cross-cultural communication needs more than word-for-word accuracy.

Modern software is built from thousands of smaller components, any of which could be secretly tampered with. Without full traceability, a single compromised piece can quietly infect software used by millions.

Hospitals, power plants, and water systems increasingly run on connected computer systems that can be targeted remotely. A serious attack on any of these could cause harm far beyond the digital world.

Once powerful enough quantum computers exist, they may crack the encryption that currently protects banking, health records, and private communication. Most of the internet still isn't ready for that shift.

We know roughly when life began, but not the exact chemical steps that turned non-living matter into something that could reproduce. Solving this would also tell us where else in the universe life might arise.

Develop public budgeting tools that reveal spending, contracts, service outcomes, and tradeoffs in ways ordinary residents can meaningfully use.

The absence of robust, context-adapted solutions for grid-forming control for fully inverter-based power systems creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.
