How plants' threat-detection mechanisms raise the alarm

New work led by Carnegie's Zhiyong Wang untangles a complex cellular signaling process that underpins plants' ability to balance expending energy on growth and defending themselves from pathogens. These findings, published ...

Tracing the remnants of Andromeda's violent history

A detailed analysis of the composition and motion of more than 500 stars has revealed conclusive evidence of an ancient collision between Andromeda and a neighboring galaxy. The findings, which improve our understanding of ...

How do plants know how big to grow?

Organisms grow to fit the space and resources available in their environments, leading to a vast diversity of body sizes and shapes within a population of the same species. What are the genetic and physiological mechanisms ...

Can algae unlock the secrets of photosynthesis?

A team led by current and former Carnegie plant biologists has undertaken the largest ever functional genomic study of a photosynthetic organism. Their work, published in Nature Genetics, could inform strategies for improving ...

What can plants learn from algae?

Algae have a superpower that help them grow quickly and efficiently. New work led by Carnegie's Adrien Burlacot lays the groundwork for transferring this ability to agricultural crops, which could help feed more people and ...
