World Solve

Future progress on human development and planetary health depends on solving software updates stopping. Conventional approaches have proven insufficient. The required intervention must integrate community knowledge, data and appropriate technology while remaining affordable, privacy-preserving and operable with minimal external support. Strong solutions will articulate measurable impact metrics, risk mitigation strategies, and a plan for sustained operation by local actors after the pilot phase.

Addressing stop and search remaining unfair is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

The problem of stigma stopping people from seeking help continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals. Existing responses remain fragmented, under-resourced and poorly adapted to local contexts. A strong solution must operate effectively under severe constraints of skilled personnel, infrastructure, electricity and connectivity. It should define clear measurable outcomes, identify possible unintended harms, and demonstrate how the intervention can be sustained by local institutions long after initial funding ends.

Lifts that stop between floors to prompt destination second-thoughts can induce anxiety or delay. The challenge is allowing reflective moments without forcing hesitation as a system default.

The technical problem is coupled with a social allocation problem: production varies, meters may be imperfect, and residents need rules they trust. Tariff design, optimization, and transparent settlement tools could make shared generation investable. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with forecast uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Many connected devices become permanently vulnerable once their manufacturer stops issuing security updates, yet the devices often remain in active use for years afterward. A sustainable way to keep abandoned devices secure remains unresolved.

Recommendation systems tend to show users more of what they already agree with because that content performs better for engagement, gradually narrowing exposure to differing viewpoints. Correcting for this without reducing relevance remains an unresolved design challenge.

Counterfeit electronics, from chargers to batteries, sometimes skip proper safety certification entirely, creating fire and shock risks for unsuspecting consumers. Detecting and stopping these products at scale remains an unresolved supply chain challenge.

Companies sometimes stop providing security patches for older but still commonly used software or devices, leaving users vulnerable without clear warning. Establishing consistent, enforced support timelines remains an unresolved industry practice.

Content about topics like drug use, violence, or self-harm can be either genuinely educational or genuinely harmful depending on context and intent, and automated filters still struggle to reliably tell the difference. This creates ongoing tension between safety and access to legitimate information.

AI-powered chatbots can now conduct long, personalized, convincing conversations designed to manipulate victims into financial scams, operating at a scale no human scammer could match. Detecting and stopping this abuse remains an evolving challenge.

A few seconds of someone's voice is now enough to generate convincing fake audio of them saying anything, and current detection tools often fail to catch high-quality fakes in real time. This is already being used for financial scams targeting families and businesses.

Ransomware groups increasingly target hospitals, schools, and utilities precisely because the disruption pressures victims to pay quickly. Defenses have improved, but attackers are still winning often enough to make this an ongoing crisis.

Citizens navigate multiple portals and in-person visits for basic services. One-stop e-government platforms and identity systems can improve experiences.

Tech-driven initiatives can feel top-down, raising privacy and inclusion concerns. Co-design platforms and impact assessment tools could improve legitimacy.

Alternative theories predict deviations that current experiments are only beginning to probe. More sensitive tabletop experiments are needed.

Running couplings suggest possible metastability of the vacuum. Improved measurements of Higgs and top masses refine stability assessments.

Observed exoplanet diversity challenges simple core-accretion models. High-resolution imaging of disks and improved simulations are needed.

Dust growth, fragmentation, and migration shape planet formation but are complex. Combined observation and modeling efforts are needed.

Galaxies stop forming stars due to feedback and environment, but mechanisms vary. Surveys across environments and redshifts can clarify.
