World Solve

Wealthier countries can screen for many rare genetic conditions at birth, but most of the world's newborns are never tested. Expanding this access could catch treatable conditions before irreversible damage occurs.

Detecting serious illness usually still requires multiple separate tests, doctor visits, and significant cost, which many people simply skip. A single affordable screening test could catch problems that currently go unnoticed for years.

Depression, anxiety, and other mental health conditions often go undetected until symptoms are already severe. Earlier, more reliable prediction could allow prevention instead of just treatment after the fact.

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.

By the time illegal logging is discovered, the trees are often already gone and the damage is done. Real-time detection and enforcement could protect forests before, not after, they disappear.

Fake videos and voice clones are now realistic enough to fool most people, and detection tools often lag behind the technology creating them. Left unresolved, this threatens trust in video and audio evidence itself.

AI can now produce convincing text, images, and video in seconds, and detection tools are struggling to keep up. Without a reliable way to tell real from fake, public trust in what we see online keeps eroding.

Current detectors cost billions of dollars and can only catch the largest cosmic collisions. A cheaper detection method would let us study the universe's most violent events far more often.

We can now detect many dangerous asteroids years in advance, but we still lack a proven way to redirect or destroy one heading for Earth. One unlucky strike could cause damage on a civilization-ending scale.

Dark matter and dark energy make up roughly ninety five percent of the universe, yet we've never directly detected either. Everything we can see and touch is a small fraction of what's really out there.

Every search so far has come back empty, but our tools for detecting distant life are still crude. Knowing the answer would reshape biology, philosophy, and how we think about our place in the universe.

Despite recognition of its importance, reliable methods for real-time systems for detecting and responding to food safety threats across supply chains are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

A persistent gap exists in realizing practical, scalable solutions for affordable methods for the early detection and treatment of the major cancers in LMICs. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.

Build affordable monitoring and response systems that identify local environmental threats before they become chronic public-health crises. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.

Translate quantum sensing advances into rugged, affordable tools for detecting pollutants, groundwater changes, magnetic anomalies, and infrastructure defects.

Develop practical biomonitoring and exposure assessment for workers in recycling, dyeing, tanning, metalwork, and small manufacturing.

Develop accurate sensors, sampling methods, building diagnostics, and remediation guidance for homes, schools, and workplaces.

Develop privacy-respecting tools that help detect progression and treatment response in Parkinson's, epilepsy, dementia, and other disorders outside specialist centers.

Develop detection, remediation, legal accountability, secure-device access, and emergency support systems for targeted civil-society actors.
