US to report major fusion breakthrough

December 12, 2022
MThomas

The Financial Times reported Sunday that scientists in the California-based Lawrence Livermore National Laboratory (LLNL) had achieved a “net energy gain” from an experimental fusion reactor.

This is being spread across various websites. FT and Washington Post wrote the most details, but both are behind paywalls (boo) so I cited NDTV instead.

If…a BIG if…this report is true, it would still take a decade or more to commercialize fusion to the point where it would make even a dent in climate change.

But it would be a big first step.

A BIG if.

(FWIW, European scientists claimed this back in February …and in June… and again in September, and then it all fizzled out. So I’m not holding my breath on yet another politically charged, puff out our nationalist chest claim until I see scientific evidence that the reaction can be sustained and repeated elsewhere.)

Can you say “billlyons and billyons of dollars”?

Neuroscience and the ethics of mind control

“Embedding a similar type of computer in a soldier’s brain could suppress their fear and anxiety, allowing them to carry out combat missions more efficiently.”

Sounds like science fiction, but it’s pretty close to reality. BCI (brain computer interface) is being tested in patients who lack muscle control but imagine if this tech gets weaponized (and what hasn’t been, eventually).

But what if BCI were used to suppress emotions in a healthy brain? Or used to implant thoughts? Or worse?

“…if a BCI tampers with how the world seems to a user, they might not be able to distinguish their own thoughts or emotions from altered versions of themselves…”
(same website as above…note that the PC version of WordPress does not do “quotations” correctly any more…)

PKD fans will instantly recognize this.

Androids don’t just dream of electric sheep. 🐑

(Fans of Ghost in the Shell and more importantly its movie sequel Innocence should also recognize the potential hacking danger…imagine if the government could control our emotions, thoughts, and memories…)

Why Japan and JAXA are definitely NOT the future of space exploration

Falsified space research? No problem. The “apology bow” (sha zai, 謝罪) makes it all better.

There is a reason why Japan’s newest “micro” satellite spectacularly failed to do, well, anything.

The Japan version of NASA (Japan Aerospace Exploration Agency, called “JAXA” for some reason rather than “JAEA” — maybe the founder was a fan of X-Japan?) is riddled with incompetency and sycophancy.

Much like the rest of Japan’s government, one of the most corrupt of the world’s industrialized countries thanks to its strict “senpai-kohai” hierarchy where those at the top do no work and those at the bottom have no choice but to do what those at the top say – even if it’s illegal or immoral.

DART did it! 🎯

“For the first time ever, humanity has changed the orbit of a planetary body,” said NASA planetary science division director Lori Glaze.
https://www.sciencenews.org/article/dart-mission-deflected-asteroid-for-planetary-defense

A change of 32 minutes in orbit — but only 4% of the total orbital period. To deflect an asteroid away from Earth, it’d better be done several years in advance. 🌏

Still, it can be done. An amazing first.

Attack of the Killer Drones — Non-fiction not fiction?

These aren’t the drones that deliver your online order. Loaded with cameras, sensors, and explosives, their mission is to drive themselves to a target with an algorithm in the driver’s seat. They destroy themselves along with the target, leaving behind just a pile of electronic detritus.

Oh, joy. I can’t wait to see what happens when we program 3D printers to churn them out.

Or just simply make them self-replicating. What could possibly go wrong?

Carl Sagan at the Illinois ACLU: A lost 1987 lecture on civil liberties

July 1, 2022
MThomas

…there has been a serious erosion of the tradition of skeptical inquiry, of vigorous challenging of government leaders, of public exposure of what the government is actually doing, rather than mere pomp and rhetoric. And it is in this area—skeptical scrutiny, public exposure—where the largest strides, in my opinion, are needed.

Thank you, Stephen Pinker and Harvey Silverglate, for transcribing this. And Ann Druyan, for permitting it.

The University of Tokyo just covered a robot finger with real skin. The jokes write themselves…

Skin is also just the first step in combining organic matter with machines, and opens the door for incorporating nerves and sensory organs such as olfactory receptors which can detect scents.
https://soranews24.com/2022/06/16/robot-finger-covered-in-living-skin-developed-by-university-of-tokyo/

The original report was published online by the U of Tokyo before it was covered last week by several online sources, including WebMD, the Independent, France 24, and ABC7, but the Sora News is the only one to post Japanese reader comments about, well, what fingers can do. Ahem.

The final quote of the researchers was posted on WebMD as:

“We believe this is a great step toward a new biohybrid robot with the superior functions of living organisms.”

Eek. Maybe might wanna rethink this…

Plants can grow in lunar soil (barely)

May 16, 2022
MThomas

The samples were extremely hydrophobic, and repelled water as if it were the most disgusting thing ever invented. Researchers labored to get the lunar soil to gradually soak up water. They also added a nutrient solution.
https://www.washingtonpost.com/science/2022/05/12/plants-grow-in-lunar-soil/

Turns out that it is possible to grow plants on the Moon…

…although you might want to wear gloves while farming, since the “soil” contains tiny pieces of glass from constant bombardment.

Let’s make rocket fuel with E. Coli!

In short, the algae will use sunlight to transform CO2 into sugars that are then enhanced by bio-engineered E.coli into 2,3-butanediol. Interestingly, 2,3-BDO is not entirely conceptual as it currently exists and is mainly used to produce rubber components. It has just never been thought of as fuel before.
https://www.universal-sci.com/article/producing-rocket-fuel-on-mars-using-microbes?utm_campaign=Universal-Sci%20Weekly&utm_medium=email&utm_source=Revue%20newsletter

Neat. So all the astronauts have to do is bring, uh, how much algae we talking here?

The article doesn’t say, but it does mention a by-product of the process: Oxygen!

That would seem rather helpful. Mars or bust?

Meet the man who was Shatner’s eye

www.washingtonpost.com/magazine/2022/03/22/star-trek-movie-shatners-eyeball/

The iconic “retina scan” scene in Star Trek II: Wrath of Khan was not Shatner’s own eye.

It was an “eye double” software engineer.

(As the man himself says, your iPhone can take a more detailed picture these days, but it was high tech for 1982…)
