Phosphate polymer forms a cornerstone of metabolic control

In a changing climate, understanding how organisms respond to stress conditions is increasingly important. New work led by Carnegie's Arthur Grossman and Emanuel Sanz-Luque could enable scientists to engineer the metabolism ...

Assessing controls on ocean productivity—from space

Phytoplankton determine how much life the ocean is able to support and play a role in controlling atmospheric carbon dioxide concentrations, thereby regulating our climate. These tiny marine plants depend on sunlight as well ...

The benefit of redundancy in biological systems

When viewed from an engineer's perspective, biology is often messy and imperfect. For example, redundancy is a common feature of biological systems, with the job of one biological component overlapping with that of another.

Major limnology paradigm questioned by new study

Shallow lakes can take on two alternative stable states, according to a theory on ecological equilibrium in the study of inland waters (limnology). This paradigm has now been called into question by a study conducted by the ...
