Organelles grow in random bursts

New experiments that show that eukaryotic cells can robustly control average fluctuations in organelle size. By demonstrating that organelle sizes obey a universal scaling relationship that scientists can predict theoretically, a new framework suggests that organelles grow in random bursts from a limiting pool of building blocks.

New discovery of sunscreen-like chemicals in fossil plants reveals UV radiation played a part in mass extinction events

New research has uncovered that pollen preserved in 250 million year old rocks contain compounds that function like sunscreen, these are produced by plants to protect them from harmful ultraviolet (UV-B) radiation.
