Soil bacterium from Earth can both make and repair bricks made from Moon-materials
Researchers in India have now discovered that the same soil bacterium from Earth they used to manufacture bricks made from Moon-materials can also act to repair cracks in those bricks.
A few years ago, researchers at the Department of Mechanical Engineering (ME), IISc developed a technique that uses a soil bacterium called Sporosarcina pasteurii to build bricks out of lunar and Martian soil simulants. The bacterium converts urea and calcium into calcium carbonate crystals that, along with guar gum, glue the soil particles together to create brick-like materials. This process is an eco-friendly and low-cost alternative to using cement.
… In a new study, they created different types of artificial defects in sintered bricks and poured a slurry made from S. pasteurii, guar gum, and lunar soil simulant into them. Over a few days, the slurry penetrated into the defects and the bacterium produced calcium carbonate, which filled them up. The bacterium also produced biopolymers which acted as adhesives that strongly bound the soil particles together with the residual brick structure, thereby recovering much of the brick’s lost strength. This process can stave off the need to replace damaged bricks with new ones, extending the lifespan of built structures.
These results are encouraging but not necessarily for space exploration. This research can likely be applied with great profit here on Earth to repair damaged materials already in place.
As for using it in space or on the Moon, great uncertainties remain, such is whether the bacteria could even survive or function in a different gravity environment. The team hopes to test this on one of India’s planned Gangayaan manned missions.

Minnesota school brings sanity back to the classroom by banning smart phones
The smart phone: Proven very bad for kids
Making schools productive again: A Minnesota middle school has found that banning smart phones from all students during the school day has improved behavior both in and out of the classroom while improving the learning and social environment.
“I believe (the ban) is game-changing and will have lasting impacts on our students for years to come,” Maple Grove Middle School Principal Patrick Smith told WCCO. “There was no cross-the-table conversations, there was no interaction in the hallways,” he said. “And let’s be real, with these devices, our students – especially our teenagers – there’s a lot of drama that comes from social media, and a lot of conflict that comes from it.”
Last year, school officials banned student cell phone use for the entire school day, from 8:10 a.m. to 2:40 p.m., following a variety of issues at the school tied to the devices. “We have a culture and climate concern. We see issues that kids are getting on their phones through interactions of bullying, of setting up fights, just the gambit of a lot of the negative things kids are going back and forth on social media,” Smith said on the Chad Hartman Show, adding that the distraction from learning was also a major concern.
After a year school officials and parents are enthused by the results. Not only has the social atmosphere improved at the school, parents are reporting improvements in learning in their kids.
None of this is a surprise. » Read more

Rollerman – Downhill extreme
In U.S. sales of dumb phones are up
It appears that American users of mobile phones are shifting every so slightly away from smart phones, with sales of simple flip-phones lacking a screen rising in the past year.
In the U.S., feature flip phone sales were up in 2022 for HMD Global, with tens of thousands sold each month. At the same time, HMD’s global feature phone sales were down, according to the company.
In 2022, almost 80% of feature phone sales in 2022 came from the Middle East, Africa and India, according to Counterpoint Research. But some see that number shifting, as a contingency of young people in the U.S. revert back to dumb or minimalist phones. “In North America, the market for dumb phones is pretty much flatlined,” said Moorhead. “But I could see it getting up to 5% increase in the next five years if nothing else, based on the public health concerns that are out there.”
Companies like Punkt and Light are catering to the trend, selling devices geared toward those with a desire to spend less time on their phones and social media. On YouTube, you will find a slew of influencers touting these phones.
It is not clear if this is a real trend, or merely a bit of press release salesmanship by HMD and others. If it is however I think it is a good trend. Smart phones do very little to make people smarter. Instead, they foster a shallow thinking process focused on emotion. The more people who get away from them the better.

Touring the largest organ in the world
An evening pause: Specifically, this tour takes us from the bottom to the top of the largest pipe, and then shows us what comes out when you play it.
Hat tip Judd Clark, who provides this additional information:
Constructed between May 1929 and December 1932, the Main Auditorium Organ is the “Poseidon”, built by the Midmer-Losh Organ Company, and is the world’s largest pipe organ. Also included in this organ are pipes operating on 100 inches of pressure, the Grand Ophicleide being the loudest and also most famous. The instrument has an estimated 33,113 pipes and requires approximately 600 horsepower (450 kW) of blowers to operate.

Last 747 rolls off assembly line
Boeing earlier this week completed assembly of its very last 747 airplane, the 1,574th such plane built in the past half century.
Still in its iridescent green protective coating, the giant aircraft was towed out of the widebody aircraft factory in a low-key exercise without any fanfare. Once the 747 has been cleared, it will be flown to another Boeing facility where it will be painted in the Atlas Air livery in anticipation of final delivery to the customer next year.
The 747 was born out of a failed bid by Boeing to market a large jet transporter to the US military in the 1960s. That contract for what became the C-5A Galaxy eventually went to Lockheed, but Boeing was convinced that its basic design, with its high-bypass turbofan engine, could be reworked for the civilian market, which was booming at the time.
On January 9, 1969, the first 747 prototype took to the skies over Washington state. It was a staggering 225 feet (68.5 m) long, had a wing area larger than a basketball court, and the tail was as high as a six-story building.
Without question the 747 was one of the safest and well designed airplanes ever built. It was years after that first flight before one was involved in an accident, and that was not due to a failure of the plane itself. It also flew like a dream, its large size making it look like it was lumbering slowly in the air. Its retirement is almost entirely related to fuel cost-savings, since the 747 has four engines and thus more fuel than more modern planes.

Dumping Windows and Apple and switching to Linux
My regular readers know about my utter contempt for Microsoft and its terrible Windows operating system. Any company that treats its customers like dirt, as Microsoft routinely does, does not deserve the business of anyone. I realized this reality two decades ago, and successfully switched to Linux back in 2006. I have never regretted it.
Moreover, the increasingly intolerant behavior of big tech companies like Microsoft to free speech increases the need for people to free themselves from them. The willingness of these companies to also treat your privacy and personal data as a plaything for their use, without your permission, is another rational reason to stop depending on them.
Linux accomplishes this, in that its open source software structure is really controlled by no one. There is also no software company using the operating system to gather your data for its own purposes.
In 2016, after seeing a number of my posts noting the advantages of Linux (or anything) over Windows, one of my readers, James Stephens, offered to write a series for Behind the Black describing step-by-step the process by which one gets and installs Linux on either a desktop or laptop computer. Below are the links to this series. I have since used it myself as a guide to convert two used Windows 7 notebooks (purchased for $35 and $80) to my favorite flavor of Linux, both of which I use regularly as my travel computers.
I wish more people would do the same, which is why I am reposting the links to this series again. Though six years have passed, James instructions still apply perfectly, as I can attest as I used this series to convert the second laptop only a year ago. Nonetheless, James has added an addendum to Part 2, which brings the entire series up to date.
I am sure almost everyone has an old computer they don’t use anymore. It will work like new with Linux. Dig it out, follow James’ instructions below and free yourself from Windows. I guarantee you will not be disappointed.
