Department of WTF, Nobel bureau

This year's winners of the Nobel Prize in physics studied graphene, which is basically a flat layer of benzene rings all connected together. They had an unconventional way of the obtaining the material:
Graphene is a form of carbon in which the atoms are arranged in a flat hexagon lattice like microscopic chicken wire, a single atom thick. It is not only the thinnest material in the world, but also one of the strongest. If scaled up to the thickness of plastic refrigerator wrap, a sheet of graphene stretched over a coffee cup could support the weight of a truck bearing down on a pencil point, according to tests conducted by two Columbia University researchers, Jeffrey Kysar and James Hone...

Graphene is closely related to two other forms of carbon that have generated intense interest in recent years: buckyballs, which are soccer-ball arrangements of carbon atoms, and nanotubes, which are rolled-up sheets of carbon atoms. It was long thought, however, that an essentially two-dimensional sheet of carbon atoms would be unstable and would warp or fold up. Dr. Geim and Dr. Novoselov first succeeded in creating flakes of graphene by peeling them off piles of graphite — the material that is in your pencil lead — using Scotch tape.
Science is awesome.

Why Did Reality Winner Leak to the Intercept?

So Reality Winner, former NSA contractor, is in federal prison for leaking classified information — for five years and three months, the longest sentence of any whistleblower in history. She gave documents on how Russia had attempted to hack vendors of election machinery and software to The Intercept , which completely bungled basic security procedures (according to a recent New York Times piece from Ben Smith, the main fault lay with Matthew Cole and Richard Esposito ), leading to her capture within hours. Winner recently contracted COVID-19 in prison, and is reportedly suffering some lingering aftereffects. Glenn Greenwald has been furiously denying that he had anything at all to do with the Winner clusterfuck, and I recently got in an argument with him about it on Twitter. I read a New York story about Winner, which clearly implies that she was listening to the Intercepted podcast of March 22, 2017 , where Greenwald and Jeremy Scahill expressed skepticism about Russia actually b

Varanus albigularis albigularis

That is the Latin name for the white-throated monitor lizard , a large reptile native to southern Africa that can grow up to two meters long (see pictures of one at the Oakland Zoo here ). In Setswana, it's called a "gopane." I saw one of these in my village yesterday on the way back from my run. Some kids from school found it in the riverbed and tortured it to death, stabbing out its eyes, cutting off its tail, and gutting it which finally killed it. It seemed to be a female as there were a bunch of round white things I can only imagine were eggs amongst the guts. I only arrived after it was already dead, but they described what had happened with much hilarity and re-enactment. When I asked why they killed it, they said it was because it would eat their chickens and eggs, which is probably true, and because it sucks blood from people, which is completely ridiculous. It might bite a person, but not unless threatened. It seems roughly the same as killing wolves that

The Conversational Downsides of Twitter's Structure

Over the past couple years, as I've had a steady writing job and ascended from "utter nobody" to "D-list pundit," I find it harder and harder to have discussions online. Twitter is the only social network I like and where I talk to people the most, but as your number of followers increases, the user experience becomes steadily more hostile to conversation. Here's my theory as to why this happens. First is Twitter's powerful tendency to create cliques and groupthink. Back in forum and blog comment section days, people would more often hang out in places where a certain interest or baseline understanding could be assumed. (Now, there were often epic fights, cliques, and gratuitous cruelty on forums too, particularly the joke or insult variety, but in my experience it was also much easier to just have a reasonable conversation.) On Twitter, people rather naturally form those same communities of like interest, but are trapped in the same space with differe
