NANOTECHNOLOGY: The Nobelists and Their Molecular Machines. “While these incremental steps remain pretty far from the self-repairing machines envisioned by Eric Drexler in his book ‘Engines of Creation: The Coming Era of Nanotechnology,’ Granja believes these steps are what will eventually lead us there. One of the things that seems to be increasingly clear is that nanomachines are looking to be more biological than machine-like bots.”

FLASHBACK: InstaPundit Is Not A News Service.

EARLIER I MENTIONED THIS POST by Eugene Volokh, on other people’s insistence that he blog topics of interest to them, regardless of whether they were of interest to him. (Pejman also weighs in on this, offering to blog anything the demanders demand, for an adequate fee: “Kids, I’m a lawyer. I’m trained to do this kind of thing!” That’s why I quit practicing law, Pej.)

I don’t have much trouble resisting people’s efforts to bully me into advancing their agendas. What worries me more, in a way, are the friendly emails from people saying that they get all their news from InstaPundit.

Don’t do that! It’s “InstaPundit,” not “InstaNews Service.” And this is, as Eugene properly notes, an amateur activity. I don’t even get to blog all the stuff that interests me — I’ve really fallen behind on space, guns, and even nanotechnology lately– much less stuff that’s important, but that doesn’t interest me.

What you get here — as with any blog — is my idiosyncratic selection of things that interest me, as I have time to note them, with my own idiosyncratic comments. What’s more, to the (large) extent that it’s shaped by my effort to play up stories that Big Media are ignoring, it’s even more idiosyncratic. I hope you like it, but making it your sole source of news is probably not a good idea. It’s like living solely on appetizers and desserts: there’s no “four food groups” approach here. [Maybe InstaPundit is more like a dietary supplement — providing essential nutrients, not basic sustenance? — Ed. That’s it: “InstaPundit: The Cod Liver Oil of the Media World!” Actually, now that I think about it, I like the dessert analogy better. –Ed.]

I mention this because (1) Trump’s dominating the news like nobody’s business; and (2) InstaPundit is, to a huge degree, a media-criticism blog. So Trump stuff is taking up a bigger share of space than maybe it should. I’ll do my best to counterbalance that (and so will the cobloggers) but bear in mind, InstaPundit wasn’t a news service in 2003, and it’s still not one in 2017. That is all.

CHANGE: Indium Selenide Takes on the Mantle of the New Wonder Material. “The semiconductor bit has always been the showstopper for graphene. Because it lacks a natural band gap, that property has to be engineered; but that takes away some of its attractive properties in terms of electron mobility. The form of indium selenide the Manchester researchers have developed has an inherent band gap, and thus requires no gerrymandering that might compromise its high electron mobility. In research published in the journal Nature Nanotechnology, the Manchester researchers found that the indium selenide had a room-temperature electron mobility of 2,000 square centimeters per Volt-second, which is significantly higher than that of silicon and even higher than few-layer dichalcogenides.”

Their finding, which involves nanofabrication and catalysis science, was serendipitous.”

NANOTECHNOLOGY UPDATE: Nobel Prize in chemistry goes to scientists who made molecular machines.

Three scientists whose independent work led to the development of molecular machines with controllable movement won the 2016 Nobel Prize in chemistry, the organization announced Wednesday.

The Royal Swedish Academy of Sciences awarded the prize to Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa, who will share a prize of nearly $1 million.

“The development of computing demonstrates how the miniaturization of technology can lead to a revolution,” The Royal Swedish Academy of Sciences wrote in a statement. “The 2016 Nobel laureates in chemistry have miniaturized machines and taken chemistry to a new dimension.” . . .

The academy added that this year’s chemistry Nobel laureates took “molecular systems out of equilibrium’s stalemate and into energy-filled states in which their movements can be controlled.”

“In terms of development, the molecular motor is at the same stage as the electric motor was in the 1830s, when scientists displayed various spinning cranks and wheels, unaware that they would lead to electric trains, washing machines, fans and food processors,” the academy wrote. “Molecular machines will most likely be used in the development of things such as new materials, sensors and energy storage systems.”

I’ve been writing about this stuff for a long time. It’s nice to see it becoming reality. Meanwhile, the Foresight Guidelines for responsible nanotechnology development are worth mentioning again.

NANOTECHNOLOGY UPDATE: Less Talk, But Plenty Of Action:

Nobody in the stock market gets excited about the phrase “nanotech” anymore. Which is strange, because nanotechnology itself – that is, the science and engineering conducted on a molecular scale, measuring less than 100 nanometers – is yielding applications and products in a number of industries, just as its more sensible supporters have long predicted. . . .

According to Google Trends, searches on “nanotechnology” have steadily trended downward to between 15% and 20% of the levels of a decade ago. Searches for “nanotech” – the catchy buzzword preferred by investors – have grown even quieter. And yet each year there are more interesting applications that wouldn’t be possible without nanotechnology.

One better-known example is semiconductors, which began employing a 65-nanometer manufacturing process in 2007. Intel this year announced a processor with transistors measuring 14 nanometers, small enough to fit 1.3 billion transistors on a chip, and is pushing for a 10-nanometer process.

Meanwhile, research for new drug therapies are increasingly relying on molecular-level science, while gold nanoparticles are being developed as way to diagnose and treat cancers. Touchscreens, LEDs, displays, batteries, water desalination, energy efficiency – all are areas that are benefiting from nanoscience, with products already in the market or approaching there. IBM, for example, is looking into carbon nanotubes as a promising alternative to silicon, which isn’t useful in transistors below 10 nanometers.

Nanotechnology never had its Facebook, its multibillion dollar blockbuster IPO that made clear how a new technology is changing the world. Instead, it’s enabling a lot of mostly incremental change in older industries. It may not be as visible as a social network, but it’s even more widespread. Most of the investments, however, have been coming not from VCs but from governments or deep-pocketed, diversified giants like IBM or GE.

That’s good.
