Black pod disease destroys up to a quarter of the world's cacao every year, roughly 700,000 metric tons worth more than $2 billion. The water mold responsible across the Americas …
Without water, forests lose their ability to absorb CO₂
To survive periods of drought, trees halt photosynthesis, a highly water-intensive process. For every molecule of CO₂ absorbed by a tree leaf, an average of around 400 water molec…

Blue-light tools let researchers track, redirect and sever cells' transport routes
Light is fundamental to human life—without it, we'd be hungry, cold and blind. But what if the same light that sustains us could also be used to control and observe parts of cells…
