The Dish

Are there equally as many neurons in the human brain as stars in the Milky Way? Bradley Voytek provides the latest data on the subject, then walks us through how scientists arrived at the numbers:

Even though we can’t conceive of the number of stars in the Milky Way or the number of neurons in the human brain, equating the two gives people a sense of enormity. And as conscious beings we like to find patterns, and we find equivalencies interesting, especially when the things being equated are “important” or “epic” (like neurons and stars).

For a long time, neuroscientists would say that there are about 100 billion neurons in the human brain. Interestingly, no one has ever published a peer-reviewed scientific paper supporting that count. Rather it’s been informally interpolated from other measurements. A recent study from 2009 published by Azevedo and colleagues took a crack at a more precise estimate. Their answer?

Approximately 86 billion neurons in the human brain. The latest estimates for the number of stars in the Milky Way is somewhere between 200 and 400 billion. So close, but the human brain certainly doesn’t quite stack up!

On the heels of new discoveries by the International Institute for Species Exploration (IISE), Sarah Soat explains why taxonomy matters:

Only about two million of the estimated 10 to 12 million living species have been identified. (We’re talking plants and animals; microbes are another 20 million-plus story.) And in an era where the rate of species extinction may exceed species discovery, [IISE founding director Quentin] Wheeler reasons that millions of species may not survive the 21st century. So it’s important—urgent, even—to establish a baseline of species to give us the necessary facts to monitor these changes as they happen. Without a major taxonomic initiative, Wheeler told me, “We are literally flying blind into a storm and hoping for a safe landing.”

The Maria Bamford Show is the brainchild of standup comic Maria Bamford, whose sensibility is, according to Madeleine Davies, “as unique as it is necessary”:

Perhaps what’s most special about Bamford’s goofy, surreal and stylized brand of humor is that it doesn’t end up seeming stylized at all. At times, she comes off as so intensely fragile and vulnerable that you want to hug her and tell her that everything will be alright. Then, with remarkable skill, she’ll flip it around and force you to stare your own reaction in the face — why do you assume that there’s something wrong with a person who gets on stage and says something hard and honest? Why should that kind of bravery be perceived as weakness that needs comforting rather than empathy?

While acknowledging that international observers sometimes overstep their role, Judith Kelley pushes back against calls to replace them with African counterparts:

[I]t is not quite the time to boot out the observer organisations from the wider international community. Despite their problems, they have made important contributions, particular where they’ve worked with local officials to improve voter registries, implement other institutional reforms to bolster election processes, improve the legitimacy of competitive elections, and train domestic observer groups. Furthermore, whatever legitimate concerns there are around the role of international observers, African organisations have the same problems, only worse. With so many autocratic states and tentative democracies still on the continent, African monitoring organisations still have some way to go before they are ready to hold each other accountable.

A woman feels less alone after reading this post:

He had this long knife in his hand. He had a rag over his head so I could not see his face even though it (and he), were dark as death at the time. He was inside me. He smelled like he had been sleeping in shit-garbage for weeks. His dick was soft and he was struggling to have his orgasm.

And my body moved against him. Just once. Maybe a few seconds of time that in my memory has always been a long and very sick movie. One of those dreams that leaves you with a hole-in-your-heart feeling that never goes away.

I do not know who was more shocked. Me or him. He froze. I froze. I know what a cold sweat is. It is instant, wet and freezing. I thought he would kill me right then for sure. The knife blade was shining. He said “What are you doing?” He said it roughly. I kept silent. I did not know what to say. I have never known what to say about this. Not known what to think of myself.
