Modern men’s genes suggest that something peculiar happened 5,000 to 7,000 years ago: Most of the male population across Asia, Europe and Africa seems to have died off, leaving behind just one man for every 17 women.
This so-called population “bottleneck” was first proposed in 2015, and since then, researchers have been trying to figure out what could’ve caused it. One hypothesis held that the drop-off in the male population occurred due to ecological or climatic factors that mainly affected male offspring, while another idea suggested that the die-off happened because some males had more power in society, and thus produced more children.
Now, a new paper, published May 25 in the journal Nature Communications, offers yet another explanation: People living in patrilineal clans (consisting of males from the same descent) might have fought with each other, wiping out entire male lineages at a time. Read more.
NOT!Anatomy but still interesting.
I took this picture in Beijing last week, and posted it to my FB, asking followers to guess what the stick the cop was holding, was for.
One person got it right.
The Library by Rem Koolhaas
The physical impact of books has been important in terms of my entire formation. The first books that fascinated me were the fairy tales of Grim illustrated by Gustave Doré. I still remember the physical nature of those books as one of the strongest memories of my entire life. In the 1950s I would spend time in the library of the Stedelijk Museum – almost like in a living room. My first intersection of writing and architecture was Delirious New York, which I wrote in the New York Public Library, going through microfilms, old newspapers, and books. I made one particular seat my own, almost day and night.
One similarity between architecture and bookmaking is that both have unbelievably long traditions but are also forced to be of the moment, constantly updating in order to survive. We have designed many libraries and built a few. Libraries, as a typology, are so exceptionally suitable to produce radical architecture. Apparently, there is a paradox that such a traditional form produces inventive solutions, and that is the case for the Qatar National Library. The building is 138 meters long, equivalent to the length of two 747s. This is not to boast about scale but because from the beginning the idea was to make reading as accessible and as stimulating as possible to the population of Qatar as a whole. We thought we could achieve that by creating a building that was almost a single room, not divided in different sections, certainly not into separate floors.
We took a plate and folded its corners up to create terraces for the books, but also to enable access in the center of the room. You emerge immediately surrounded by literally every book – all physically present, visible, and accessible, without any particular effort. The library is a space that could contain an entire population, and also an entire population of books…
the thing about organic chemistry is that you finally get to use all the aesthetically pleasing mad scientist looking chemistry apperatuses that you’ve been waiting to use for years but when u finally get to use them they all turn out to do surprisingly boring things
