Microbe metabolism: For the smallest organisms, size determines how microbes spend energy
Every living organism balances a budget of sorts — by allocating energy to various parts of its body to fuel essential life processes. Throughout its lifetime, an organism may rebalance this budget to ...

Climate sensitivity greater than previously believed
Many of the particles in the atmosphere are produced by the natural world, and it is possible that plants have in recent decades reduced the effects of the greenhouse gases to which human activity has given rise. One consequence ...

Model organism
A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. In particular, model organisms are widely used to explore potential causes and treatments for human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another.
