(Or at least partly factual, I don't know if we've proved that they can't read.)

  1. They can go a lifetime without water

Birds are experts in conserving water.

Along with mammals, they’re the only animals capable of concentrating urine, and this helps them reduce the water they need, thus reducing their weight and making flight a heck of a lot easier – even if they choose not to fly much.

These birds can go an entire lifetime without drinking water (technically, so can everything else, but at least in roadrunners that lifetime isn’t reduced by it), and get their moisture entirely from their diets.

Chuck Jones did the research!

Inuvik, NWT, with a 2021 census population of 3,137 is the fifth largest settlement in Northern Canada (north of the 60th parallel). At "only" 68°22′ north, it doesn't even quite make it to Wikipedia's list of northernmost settlements. But that is the most populated town in Canada whose antipodal point lies within the continent of Antarctica. The antipodal point is the point you would get to if you could drill directly down through the centre of the Earth and come out the other side (also, it is the most distant point on the surface of the Earth, which is always approx. 20,000 km from the original point). Yellowknife and Iqaluit, the capitals of the Northwest Territories and Nunavut, respectively, have antipodal points that lie at sea close to the Antarctic mainland, within a few hundred kilometres from shore.

I found that interesting because while Inuvik is certainly cold most of the time, it's still surrounded by a lush boreal forest and the warmest couple of months of summer are fairly pleasant. I've personally never been, but a friend of a friend lived there for years and still goes there. The antipodal point though is a white desert. About 300 km from that point, on the much milder coast (the antipodal point itself is more than 2000 metres above sea level), one finds Dumont d'Urville Base, a a French scientific station, which is completely barren of vegetation and is barely above freezing during summer (at least they have penguins).

The reasons for the difference in climate are many, but the Antarctic Circumpolar Current is probably mainly to blame, together with the high elevation of the surface and high albedo of the ice.

The 638 acres (2.58 km2) of land [We Build the Wall] built on is part of farmland that belongs to Neuhaus and Sons, and the wall added over $20 million in taxable land improvement, increasing the tax burden by 75 times. In January 2020, Fisher Industries started a lease-purchase agreement with Neuhaus and Sons for the land under the wall, but had not completed the ownership transfer by their court hearing on December 12, 2020, citing a problematic land survey by Fisher. Fisher's attorney, Mark Courtois, was hopeful the US government would become owners of both the wall and land. U.S. Customs and Border Protection (CBP) Public Affairs Officer Thomas Gresback said that the wall was privately paid for and on private property, and CBP does not have anything to do with the project. CBP is constructing its RGV-03 project wall outside the floodplain 0.3 miles (0.48 km) away.[66] As of July 2021, the property had been reassessed at 100 times its original value, and Fisher was hoping to sell a 3-mile section of wall (4.8 km) that had cost $30 million to build.[67]

The Shiva hypothesis, also known as coherent catastrophism, is the idea that global natural catastrophes on Earth, such as extinction events, happen at regular intervals because of the periodic motion of the Sun in relation to the Milky Way galaxy.

Initial proposal in 1979

William Napier and Victor Clube in their 1979 Nature article, ”A Theory of Terrestrial Catastrophism”,[1] proposed the idea that gravitational disturbances caused by the Solar System crossing the plane of the Milky Way galaxy are enough to disturb comets in the Oort cloud surrounding the Solar System. This sends comets in towards the inner Solar System, which raises the chance of an impact. According to the hypothesis, this results in the Earth experiencing large impact events about every 30 million years (such as the Cretaceous–Paleogene extinction event).

In other terms, West Virginia's 2020 population size was 8.3% of Florida's. As someone that grew up in Florida most of their life, I find that the culture has made a pronounced change since my childhood.

Boustrophedon is a style of writing in which alternate lines of writing are reversed, with letters also written in reverse, mirror-style.

The original term comes from Ancient Greek: "like the ox turns [while plowing]". It is mostly seen in ancient manuscripts and other inscriptions. It was a common way of writing on stone in Ancient Greece.

A fun variation is the reverse boustrophedon: the text in alternate lines is rotated 180 degrees rather than mirrored.

The reader begins at the bottom left-hand corner of a tablet, reads a line from left to right, then rotates the tablet 180 degrees to continue on the next line from left to right again. When reading one line, the lines above and below it appear upside down.

I heard about it on a podcast about the Rapa Nui people of Easter Island. They use used the reverse boustrophedon style for their system of glyphs called Rongorongo, which remains undeciphered.

From Wikipedia

Stampede events that involve humans are extremely rare and are unlikely to be fatal.[5] According to Keith Still, professor of crowd science at Manchester Metropolitan University, "If you look at the analysis, I've not seen any instances of the cause of mass fatalities being a stampede. People don't die because they panic. They panic because they are dying".[5] 

Paul Torrens, a professor at the Center for Geospatial Information Science at the University of Maryland, remarks that "the idea of the hysterical mass is a myth".[5] Incidents involving crowds are often reported by media as the results of panic.[16][17] However, the scientific literature has explained how panic is a myth which is used to mislead the attention of the public from the real causes of crowd incidents, such as a crowd crush.[18][19][20] […] [M]ost major crowd disasters can be prevented by simple crowd management strategies.[22] Crushes can be prevented by organization and traffic control, such as barriers. […] Such incidents are invariably the product of organisational failures.[4]

Replacing a broken set of blinds in my house and apparently no one sells the old standard kind where you pull the cord to raise them, I guess because kids and/or pets could tangle in the cord? Bit of an education in miniblinds today.

Relevant excerpt, emphasis is mine:

Rubio's maternal grandfather, Pedro Victor Garcia, immigrated to the U.S. legally in 1956, but returned to Cuba to find work in 1959. When he fled communist Cuba and returned to the U.S. in 1962 without a visa, he was detained as an undocumented immigrant and an immigration judge ordered him to be deported. Immigration officials reversed their decision later that day, the deportation order was not enforced, and Garcia was given a legal status of "parolee" that allowed him to stay in the U.S. Garcia re-applied for permanent resident status in 1966 following passage of the Cuban Adjustment Act, at which point his residency was approved. Rubio enjoyed a close relationship with his grandfather during his childhood.

Something shady happened, y'all.

At the age of six, Obama and his mother had moved to Indonesia to join his stepfather. From age six to ten, he was registered in school as "Barry"[31] and attended local Indonesian-language schools: Sekolah Dasar Katolik Santo Fransiskus Asisi (St. Francis of Assisi Catholic Elementary School) for two years and Sekolah Dasar Negeri Menteng 01 (State Elementary School Menteng 01) for one and a half years, supplemented by English-language Calvert School homeschooling by his mother.[32][33] As a result of his four years in Jakarta, he was able to speak Indonesian fluently as a child.[34] During his time in Indonesia, Obama's stepfather taught him to be resilient and gave him "a pretty hardheaded assessment of how the world works".[35]

In 1971, Obama returned to Honolulu to live with his maternal grandparents, Madelyn and Stanley Dunham. He attended Punahou School—a private college preparatory school—with the aid of a scholarship from fifth grade until he graduated from high school in 1979.
