We haven't found a reliable cure for chronic sinusitis that works for the majority of sufferers.

open Global / Unspecified, Global

Chronic sinus inflammation affects a large number of people and current treatments, from medication to surgery, often only partially resolve symptoms long-term. A more definitive treatment remains undeveloped.

We can't reliably regenerate damaged cartilage in joints without surgery.

open Global / Unspecified, Global

Cartilage has very limited ability to heal itself, which is why joint damage from injury or arthritis often leads to chronic pain or eventual joint replacement. Better regeneration methods could delay or eliminate the need for many of these surgeries.

We can't yet fully prevent the loss of coastal dune ecosystems that naturally buffer storm surge damage.

open Global / Unspecified, Global

Coastal dunes provide a natural barrier against storm surges, but development and recreational use continue to erode them faster than they can naturally rebuild. Protecting these ecosystems remains an underappreciated but unresolved coastal resilience challenge.

We haven't found a way to make electric grid infrastructure resilient enough to handle sudden surges from mass electric vehicle charging.

open Global / Unspecified, Global

As electric vehicle adoption grows, local power grids in many areas aren't yet built to handle the sudden, concentrated demand spikes from many vehicles charging simultaneously. Upgrading this infrastructure fast enough remains an unresolved challenge.
