Researchers discover how cells modulate macropinocytic activity

Macropinocytosis is one of the major pathways by which cells non-selectively internalize extracellular fluids. The laboratory strain Dictyostelium discoideum serves as a valuable model for studying the regulation of macropinocytosis.

Polarity proteins shape efficient 'breathing' pores in grasses

Grasses have "respiratory pores" (called stomata) that open and close to regulate the uptake of carbon dioxide for photosynthesis on the one hand and water loss through transpiration on the other. Unlike many other plants, ...

Researchers solve pre-harvest sprouting in rice and wheat

Seed dormancy is an important survival tool for plants because it allows them to weather conditions not conducive to survival. At the same time, excessive dormancy may lessen cultivation time. In response, farmers often plant ...

The evolution of evolutionary developmental biology

Studying evolution by focusing solely on fossils would leave many questions unanswered, but evolutionary developmental biology (otherwise known as "evo-devo") helps fill in the gaps.

Researchers study adolescents' life aspirations in Cambodia

Adolescents are tasked with navigating competing priorities, including whether to marry, have children, pursue a job/career, go to college, and contribute to society. A paper recently published in Developmental Psychology ...
