Dating apps like Tindr, Bumble, Hinge haven’t shaped modern relationships – it’s the other way round
https://scroll.in/article/956335/dating-apps-havent-shaped-modern-relationships-its-the-other-way-round
Anthropologist Daniel Miller and his colleagues addressed this point in their 2016 study, How the World Changed Social Media, which looked at social media use in nine different locations around the world. Unsurprisingly, it found different cultural contexts led to completely different uses of social media. The apps didn’t alter how people were behaving but rather people changed and repurposed the way the platforms worked for them.

🔴 NEUROANATOMY

🔸 The nervous system is going to get born at around 15-to-20 days of gestation.

🔸 At the beginning of this point, the embryo is a few dozen cells, and it's divided into three layers — the ectoderm, the mesoderm, and the endoderm.
And we're going to concentrate on the outer layer, the ectoderm, because that is going to become the nervous system and the skin.

🔸 Because nervous system and the skin share a developmental origin, there are disorders that happen that involve both skin and nervous system effects.

🔸 Around 15-20 days of gestation, a piece of the ectoderm becomes special — and it turns into what we call 'neuroectoderm'. And the neuroectoderm is going to form the entire nervous system.

🔸 It's going to do that in two parts.
The central part of this neuroectoderm — called neural tube — is going to become the central nervous system, which is the spinal cord and the brain.
The peripheral nervous system is formed by migratory cells, which are called neural crest cells.

🔸 And the neural crest is going to form three different types of cells of the peripheral nervous system.

1️⃣ Sensory cells: Cells that send information into the central nervous system.

2️⃣ Autonomic ganglia neurons: These are the neurons that innervate things like sweat glands, hair, folliclesm heart, the air ways, the lung, the bronchi.

🔸 And they do things that we're not in conscious control of — such as sweating, piloerection, speeding up our heart rate or slowing down our heart rate. And these all come from the autonomic ganglia.

3️⃣ Enteric Nervous System: The enteric nervous system lines the gut from the esophagus all the way down through the colon.

🔸 And this is responsible for the automatic movement of the contents of the gastrointestinal tract through the entirety of that tract from from your esophagus out until you void feces.

🔸 There are situations where there is no enteric nervous system, or more commonly where there is a reduced number of neurons in the enteric nervous system. This typically happens at birth — a newborn will be born with something called megacolon, which is exactly what it sounds like; It means that the colon is really big because it contains a lot of feces that have not been pushed out.

🔸 One of the amazing features about neural crest is that it's not devoted only to the nervous system. It also produces many other tissues that are non-neural.

🔸 For example, the pigment-containing cells, that you have both in your skin and in your hair, are called melanocytes.

🔸 The neural crest is also responsible for producing your cornea, for your aorta, for the meninges that cover the brain.

🔸 And it's also required for the correct development of teeth, for the the bones and the muscles in the face, and for the inner ear.

🔸 So, if there is a problem with the neural crest, the result will be a combination of both neural and non-neural problems. And the best example of that is a syndrome called Waardenburg syndrome.

#TIL In its original incarnation, the code points U+0A81..U+0AD0 were a direct copy of the Gujarati characters A1-F0 from the 1988 ISCII standard. The Devanagari, Bengali, Gurmukhi, Oriya, Tamil, Telugu, Kannada, and Malayalamblocks were similarly all based on their ISCII encodings.

Also, does #Gujarati not use the daṇḍa as punctuation mark? I couldn't find it on my SwiftKey keyboard; the character is not even on #Unicode. I even looked for some Gujarati articles online, hoping that they might be using the Devanagari danda, and they too were using the full-stop or period instead of the daṇḍa.

Mercury, the closest planet to the Sun, surely has no frozen water, right? Guess again: Solar winds form ice • The Register
https://www.theregister.co.uk/2020/03/17/water_mercury_ice/
❄ Here’s how they form: charged particles from the solar winds bombard the soil on Mercury’s surface. When a proton (H+) smashes into molecules containing hydroxyl groups (OH), it kicks off a chemical reaction to form water (H2O).

These water molecules rise above the surface. Sometimes they don’t survive and break apart under the sunlight. But in some cases, they float around and land in the shadows of #Mercury’s craters.

These nooks and crannies receive little light and are kept at -200 degrees Celsius. Over time, the water molecules that settle here freeze and turn into ice.

One of Darwin's evolution theories finally proved by Cambridge researcher | EurekAlert! Science News

Laura van Holstein, a PhD student in Biological Anthropology at St John's College, University of Cambridge, and lead author of the research published today (March 18) in ‘Proceedings of the Royal Society’, discovered mammal subspecies play a more important role in evolution than previously thought.
