Every time the temperature drops, a cloud passes overhead, or the sun sets, a plant makes a choice: Keep its microscopic ...

Throughout evolution, plants have continuously adapted to survive in changing environments. Apart from complex structural ...

WASHINGTON (AP) — A man who battled childhood cancer has received the first known transplant of sperm-producing stem cells, in a study aimed at restoring the fertility of cancer’s youngest survivors.

That capacity to open and close pores requires the plant to respond to subtle environmental changes by adjusting the pressure within the cells of the stomata — a complex ability that plants ...

However, they are difficult to observe in action. Each stomata is like a tiny, pressure-operated valve. They have "guard cells" surrounding an opening or pore which lets water vapour out and carbon ...

Plants shape Earth’s atmosphere by moving carbon and water vapour. New research sheds light on how they learned to do it – and how it may change in future climates.
