What Animals See in the Stars, and What They Stand to Lose
Humans aren’t the only species that navigate by starlight. Animals from birds to dung beetles may do it, too — and might become disoriented as our city lights drown out the heavens.

Middle Pleistocene fire use: The first signal of widespread cultural diffusion in human evolution
。
These archaeological data, as well as studies of ancient genomes, lead us to hypothesize that at the latest by 400,000 y ago, hominin subpopulations encountered one another often enough and were sufficiently tolerant toward one another to transmit ideas and techniques over large regions within relatively short time periods. Furthermore, it is likely that the large-scale social networks necessary to transmit complicated skills were also in place. Most importantly, this suggests a form of cultural behavior significantly more similar to that of extant Homo sapiens than to our great ape relatives.
Interaction with fire, including enhanced maintenance and production , is generally considered one of the most important processes within the cultural evolution of humankind. Fire afforded hominins protection against predators and cold, broadened the range of edible foods and the amount of energy that could be extracted from them through cooking allowed manipulation of materials extended the length of day, and impacted the character of social interactions .
Fire gave hominins a means to increase the productivity of their habitats, over time significantly transforming natural landscapes.

Single-celled organism has evolved a natural mechanical computer
https://youtu.be/CzAoJzlkzZ4 A single-celled organism that walks using 14 "legs" seems to control these legs with a mechanical computer made of fibres called microtubules . The finding might help explain how many other single-celled organisms engage in extraordinarily…

Eternal Change for No Energy: A Time Crystal Finally Made Real | Quanta Magazine
Like a perpetual motion machine, a time crystal forever cycles between states without consuming energy. Physicists claim to have built this new phase of matter inside a quantum computer.
