Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the ...

Tree rings hold clues about ancient solar storms. New research shows tree growth and carbon storage can shift those signals across years.

By Ruth Kamnitzer Regenerating tropical forests pull carbon dioxide from the air, but a lack of nitrogen in the soil could ...

Long-term data from real forests indicate leaf stomata constrain gains: carbon uptake is traded for water, keeping biomass and storage uneven.

Answer: It is a miracle, isn’t it? A small seed can grow into a mighty oak tree. That tiny seed has all the genetic code, directions, and information to become an exquisite tree with its roots, trunk ...
