Reducing nitrogen use key to human and planetary health: study
Better management of nitrogen-rich fertilizers through alternating crops, optimizing use and other measures can yield huge environmental and health benefits, but must boost food production at the same time, researchers warned Wednesday.
DNA reveals large migration into Scandinavia during the Viking age
We often think of the Vikings as ultimate explorers, taking their culture with them to far-off lands. But we may not typically think of Viking age Scandinavia as a hub for migration from all over Europe.
Coral bleaching causing 'unnecessary' fish fights
Fish that have lost food due to mass coral bleaching are getting into more unnecessary fights, causing them to expend precious energy and potentially threatening their survival, new research said Wednesday.
‘Holy grail’ wheat gene discovery could feed our overheated world
Harvests that form a vital element of the diets of 4.5 billion people are being devastated by global heating. Now research has found a key to create a heat-resistant varietyIt is the plant that changed humanity. Thanks to the cultivation of wheat, Homo sapiens was able to feed itself in ever-increasing numbers, transforming groups of hunter-gatherers struggling to survive in a hostile world into...

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.
