Male fin whales surprise scientists by swapping songs

Until now, scientists believed the male fin whale sings just one song pattern, which is unique to the males in his particular group—but new research has blown this theory out of the water. The study, published in Frontiers in Marine Science, suggests that these endangered deep-sea giants actually sing multiple different songs, which may spread to different parts of the ocean through migrating individuals. Understanding the complexity of fin whale song provides new insights into how their populations move and change over time, helping efforts to better protect and manage the world's second largest mammal.

Phytoplasma effector proteins devastate host plants through molecular mimicry

Phytoplasma are a type of bacteria that live within the cells and cause devastating diseases with damaging effects. For example, in many cases plants infected with phytoplasma are no longer able to develop flowers. These plants have actually been described as "zombies," since they allow the reproduction of phytoplasma but are unable to reproduce themselves anymore. A group of biologists based at Friedrich Schiller University and the Fritz Lipmann Institute in Germany are working to help better understand exactly how phytoplasma cells bring about the so-called zombification of plants.

History shows that societies collapse when leaders undermine social contracts

All good things must come to an end. Whether societies are ruled by ruthless dictators or more well-meaning representatives, they fall apart in time, with different degrees of severity. In a new paper, anthropologists examined a broad, global sample of 30 pre-modern societies. They found that when "good" governments—ones that provided goods and services for their people and did not starkly concentrate wealth and power—fell apart, they broke down more intensely than collapsing despotic regimes. And the researchers found a common thread in the collapse of good governments: leaders who undermined and broke from upholding core societal principles, morals, and ideals.
