(Phys.org) —A team of researchers from Grenoble University in France has found that under experimental conditions, roughly half of the noise created by drying wood is due to cavitation. The team made this discovery while ...
Many factors—including climate change, overfishing or loss of food supply—can push a wild animal population to the brink of collapse. Ecologists have long sought ways to measure the risk of such a collapse, which could ...
