We haven't solved how to make effective addiction treatment accessible to everyone who needs it, not just those who can afford it.

open Global / Unspecified, Global

Effective treatments for addiction exist, but cost and availability limits keep many people from accessing them, particularly in underserved communities. Closing this access gap remains as important as any treatment breakthrough.

We can't yet fully prevent the vision problems caused by prolonged screen use in children.

open Global / Unspecified, Global

Rates of myopia in children have been rising alongside increased screen time, and current prevention strategies remain limited and inconsistently applied. A clearer, more effective prevention approach remains an open need.

We haven't found a widely available way to prevent malaria transmission without relying primarily on bed nets and sprays.

open Global / Unspecified, Global

Current malaria prevention still depends heavily on physical barriers and insecticides, both of which face growing resistance and logistical challenges in the regions most affected. A more durable prevention method remains an urgent unmet need.

We can't yet fully explain why some people develop chronic pain conditions after relatively minor injuries.

open Global / Unspecified, Global

A minor injury sometimes triggers long-lasting chronic pain in some patients while similar injuries fully resolve in others, and the biological reason for this difference isn't fully understood. Solving this could improve treatment for a wide range of chronic pain conditions.

We don't have an effective way to prevent the recurrence of tonsillitis without resorting to surgery in many cases.
