HMM: Study: Nanoparticle therapy restores prostate cancer’s tumor suppressor.

Using nanotechnology, researchers have developed a way to treat prostate cancer by restoring tumor suppressors, based on preclinical models in the lab.

The loss of tumor suppressors, including genes such as PTEN and p53, helps cancer cells grow uninhibited.

Researchers from the Harvard-affiliated Brigham and Women’s Hospital and Children’s Hospital in Boston, as well as the Memorial Sloan Kettering Cancer Center in New York, published their findings Monday in Nature Biomedical Engineering.

While other researchers have focused on developing cancer therapies to target proteins and pathways highly active in cancer cells, the Boston-led team is studying ones that have been lost. . . .

In mouse studies, there was significant suppression of tumor growth and progression of prostate cancer. This includes prostate cancer in bones, which is the most common site to which prostate cancer can spread. The mice showed no significant side effects, including changes in body weight and organ toxicity.

Faster, please.

FASTER, PLEASE: Nanoparticles Take Solar Desalination to New Heights.

For at least the last decade, “solar thermal” technologies, in which sunlight is used to convert water into steam that runs electric turbines or performs desalination, has been a kind of darling of the investment community. About six years ago, nanoparticles started to get into this solar-thermal game when Rice University researchers added some nanoparticles to cold water and were able to make steam when they exposed the combination to sunlight.

Since then, a lot of work in what is now termed photothermal conversion has turned to the field of plasmonics, which exploits the wave of electrons that is produced when photons strike a metallic surface. However, producing plasmonic nanostructures is certainly not as straightforward as just adding some nanoparticles to water.

Now, researchers in China have combined the ease of adding nanoparticles to water with plasmonics to create a photothermal conversion process that exceeds all plasmonic or all-dielectric nanoparticles previously reported.

Cheap, easy desalination would be huge.

NANOTECHNOLOGY UPDATE: Nanomedicine inhibits progression of pancreatic cancer in mice. “The scientists performed RNA profiling and analysis of samples taken from pancreatic cancer patients. The molecular profiling revealed the same genomic pattern found earlier in mouse models of pancreatic cancer. The scientists then devised a novel nanoparticle that selectively delivers genetic material to a tumor and prevents side effects in surrounding healthy tissues.”

FASTER, PLEASE: Carbon-based filter which turns seawater into drinking water could help millions.

Reporting their findings in the Nature Nanotechnology journal, researchers from the University of Manchester have claimed that the process of desalination – filtering salt-water to produce fresh water – could lead to cheaper filtration systems in the developing world.

They explained that by controlling the size of the pores in the membranes the team was able to filter out common salts passing through the material.

“Realization of scalable membranes with uniform pore size down to atomic scale is a significant step forward and will open new possibilities for improving the efficiency of desalination technology,” Rahul Nair, professor of material physics at the University of Manchester, said in a statement.

If I’m understanding this technology correctly, it has far wider purification applications than just desalinating seawater.

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.
