Could lights stop shark attacks

Researchers develop counterillumination technology to trick great white sharks' visual systems, making them less likely to attack humans. By using LED lights in specific patterns and brightness, the device disrupts the shark's silhouette, reducing the risk of bites.

How did the division of labor emerge in animals and humans? Little-known organisms hold clues

A new study offers insight into how some colony-forming animals, like ants or bees, may have evolved their own system for divvying up work millions of years ago. Bryozoans, small aquatic animals, discovered to have evolved unique abilities after losing feeding ability, survived by sharing resources with other members of the colony.

Mental fatigue leads to loss of self-control by putting brain areas to sleep

A study published in PNAS found that prolonged mental fatigue can lead to a decrease in self-control, causing individuals to behave more aggressively. The researchers discovered that areas of the frontal cortex dedicated to executive functions showed sleep-like activity when subjects were subjected to demanding mental tasks.
