Becoming a nerve cell: Timing is of the essence
A Belgian team of researchers led by Pierre Vanderhaeghen (VIB-KU Leuven) finds that mitochondria regulate a key event during brain development: how neural stem cells become nerve cells. Mitochondria influence this cell fate switch during a precise period that is twice as long in humans compared to mice. This highlights an unexpected function for mitochondria that may help explain how humans developed a bigger brain during evolution, and how mitochondrial defects lead to neurodevelopmental diseases.

Host cell fusion in bacteria infection alarms immune system, causing host cell destruction
NUS Medicine researchers have identified a new trigger for our immune system--abnormal fusion of host cells to form giant cells after infection by pathogens such as the bacterium Burkholderia pseudomallei. Cell fusion triggered the cGAS-STING pathway, activating a type 1 interferon response which kills pathogens. In extensive cell fusion, cGAS-STING caused the giant cells to self-destruct instead. Since the DNA in the giant cells was damaged, self-destruction likely prevents these cells from becoming cancerous. (2020-07-07)

The European viper uses cloak-and-dazzle to escape predators
Research of the University of Jyväskylä demonstrates that the characteristic zig-zag pattern on a viper's back performs opposing functions during a predation event. At first, the zig-zag pattern helps the snake remain undetected. But upon exposure, it provides a conspicuous warning of the snake's dangerous defense. Most importantly the zig-zag can also produce an illusionary effect that may hide the snake's movement as it flees. The research was published in Animal Behaviour in May 2020. (2020-05-21)
