1915 👉🏼 Cecil Chubb buys English prehistoric monument Stonehenge for £6,600.
Perhaps the most famous prehistoric monument in the world, Stonehenge is also the most architecturally sophisticated, and served as an important ceremonial site and burial place from Neolithic times to the Bronze Age.
The earliest henge constructions date from 3000 BC. These took the form of circular ditches with timber structures.
From about 2500 BC the first stones were erected. Two types of stone were used, large saren stones and smaller bluestones, which were rearranged a number of times over 200-300 years and brought from considerable distance. The last major works which took place 1800-1500 BC were the digging of two rings of concentric pits.
Together with the nearby Avebury site it has been recognized as a UNESCO World Heritage site since 1986.

The feat was first performed in June 1811 at Newbury, Berkshire. John Coxeter, a mill owner, was boasting that with his new mill machinery he could perform such a task. His boasting was overheard by Sir John Throckmorton, a baronet, who set a wager of 1,000 guineas that it could not be done.

2017 👉🏼 Discovery of the first brainless animal that sleeps, the jellyfish Cassiopea, research published in “Current Biology” by Caltech scientists.
A group of students at the California Institute of Technology decided to find out one thing: if jellyfish sleep. This may seem innocuous, but jellyfish do not have brains, and scientists think sleep is rooted in a need to consolidate memory, among other things, in the brain.
So after months of late-night research, the students figured out that yes, the Cassiopea jellyfish exhibits sleep like behavior, suggesting that sleep is rooted more deeply in our biology than we realize. This makes the cassiopea the first known brainless animal to sleep – the jellyfish does not have a brain to speak of, just a diffuse set of nerve cells.
The study appears to show that sleep is a function developed very early on in the existence of life, and it has persisted, for reasons not clearly understood by scientists. Perhaps the brainless jellyfish is the answer…
