NBC News calls it “the ghostly signal that reveals the engine of the universe.” Long-time Slashdot reader fahrbot-bot shares their report:

In research published Wednesday in the journal Nature, scientists reported that they’ve made the first detection of almost-ethereal particles called neutrinos that can be traced to carbon-nitrogen-oxygen fusion, known as the CNO cycle, inside the sun. It’s a landmark finding that confirms theoretical predictions from the 1930s, and it’s being hailed as one of the greatest discoveries in physics of the new millenium. “It’s really a breakthrough for solar and stellar physics,” said Gioacchino Ranucci of the Italian National Institute for Nuclear Physics (INFN), one of the researchers on the project since it began in 1990.

The scientists used the ultrasensitive Borexino detector at the INFN’s Gran Sasso particle physics laboratory in central Italy — the largest underground research center in the world, deep beneath the Apennine Mountains, about 65 miles northeast of Rome. The detection caps off decades of study of the sun’s neutrinos by the Borexino project, and reveals for the first time the main nuclear reaction that most stars use to fuse hydrogen into helium… Scientists calculate that the CNO cycle is the primary type of fusion in the universe. But it’s hard to spot inside our relatively cool sun, where it accounts for only 1 percent of its energy…

Ranucci said the Borexino detector has spent decades measuring neutrinos from the sun’s main proton-proton chain reaction, but detecting its CNO neutrinos has been very difficult — only about seven neutrinos with the tell-tale energy of the CNO cycle are spotted in a day. The discovery required making the detector ever more sensitive over the last five years, Ranucci said, by shielding it from outside sources of radioactivity so that the inner chamber of the detector is the most radiation-free place on Earth.

ABC News tells the story of Indonesia-based budget airline Lion Air, which had ordered over 200 Boeing 737 MAX 8s at a cost of $22 billion — and what happened on a flight the day before a fatal crash on October 29th, 2018:

[A]fter its first flight in May 2017, the 737 MAX 8 went 17 months without incident. Then, on Oct. 28, 2018, Lion Air Flight 610 from Bali to Jakarta experienced an in-flight emergency as the plane suddenly began to nosedive after take-off. “All of us were screaming like we are in a roller coaster,” said Rakhmat Robbi, a passenger on the flight. “To be honest, I [was] think[ing] it’s almost like my last flight and this is my last day.” The aircraft nosedived four times as the pilots struggled to regain control, according to Indonesia’s National Transportation Safety Committee (NTSC). A third pilot who just happened to be in the cockpit was able to help the two pilots resolve the situation and the plane landed safely in Jakarta.

However, according to the NTSC, the crew left incomplete notes about the details of the emergency. “The pilot reported that he had a problem with the speed and altitude indicated on [the] captain’s side,” said Capt. Nurcahyo Utomo, senior safety investigator of the NTSC. Nurcahyo said the captain failed to mention the plane’s trim system had suddenly activated, causing it to repeatedly nose dive. “The pilots were able to control it,” said aviation attorney Steven Marks. “They knew they had a problem. But they didn’t understand exactly what the nature of the problem was.”

Early the next morning, on Oct. 29, 2018, the same plane departed from Jakarta to Pangkal Pinang, Indonesia. Just 13 minutes after takeoff, Lion Air Flight 610 plummeted into the Java Sea. Authorities launched a search and rescue mission immediately, but all 189 people on board died.

The flight data recorder from Lion Air 610 revealed that the plane had gone out of control — it had moved up and down over 24 times before it finally dove into the sea at full speed. “I never knew… any case of the [sic] aircraft that fly down and up and up and down like this,” Nurcahyo said. “I knew that the pilot was fighting with the plane.” Nurcahyo said the NTSC asked Boeing about the kind of system on the 737 MAX that could have caused it to behave in such a manner. He said investigators were surprised to learn that Boeing had installed a flight control software program that could force the plane into a dive without the pilots’ knowledge… MCAS was accidentally triggered on both Lion Air flights because a defective angle of attack (AOA) sensor had transmitted incorrect information about the position of the plane’s nose. Although there are two AOA sensors on the 737 MAX, MCAS was only connected to one of them.

“It’s a lack of redundancy that appears to me to be unacceptable in airplane design,” said aviation journalist Christine Negroni, author of the book “The Crash Detectives…”

Boeing later told the pilots union of American Airlines it hadn’t revealed the existence of MCAS in the 737 flight manual “on the grounds that it didn’t want to inundate pilots with unnecessary information,” according to the article.

ABC also points out that a later investigation by the U.S. Congress “uncovered internal Boeing emails that showed some employees had raised concerns about the 737 MAX while it was still in development, and that they had questioned the safety culture of the company as well.”

RockDoctor (Slashdot reader #15,477) is a professional geologist, and asks: Did anyone feel a sudden wind through their hair at about 17:19+00:00 on Monday, particularly in the mid Pacific? No?

Good. Nobody else did. Nobody noticed the asteroid whizzing past just above the Earth’s atmosphere (for certain values of “above” including “not very far” and “373km above ground”). That’s the closest natural body (i.e., not a spacecraft) documented in near-Earth space which hasn’t actually hit the thick-enough parts of the atmosphere to glow, fragment, make sonic booms and dent automobiles.

So, we dodged another bullet, and no windows were broken. This one probably wouldn’t have done significant damage even if it had touched down in fire and fury — it was about half the size of the 2013 Chelyabinsk meteor, and so around one eighth of the energy (and potential damage). Everyone can go back to bed and sleep easy. Right?

But one tiny thing to disturb your sleep : we didn’t see this one coming until after it had gone past us. Nor did we see it in it’s close approaches on 2014-10-26.60152 or 2017-11-06.57008. And with another 39 projected Earth approaches before the next turn-of-century, it’s pretty obvious that one day this is going to hit us.

For those who know what an MPEC is [a Minor Planet Electronic Circular], Bill Grey has written up one of his “pseudo-MPECs” with links to other work on this object here, while the actual discovery record is here. The object has been given a formal name of 2020 VT4 unless the discoverers at the ATLAS Mauna Loa Observatory choose to give it a name (“COVID”, or “hair-parter”, or “hats-off”, perhaps. Or just “Rupert”.)

Wikipedia has caught up too.

There will be another close-pass, and an impact, one day. This doesn’t change the odds of that happening (probability 1), but it might make it feel a little more immediate.

Remember when Microsoft was criticized for enabling “workplace surveillance” over “productivity scores” in its Microsoft 365 office software which gave managers highly detailed profiles of each individual employee’s activity. Long-time Slashdot reader theodp writes:
The Microsoft 365 Productivity Score apparently has roots in another Microsoft patent application for Systems, Methods, and Software for Implementing a Behavior Change Management Program, which also lays out plans for as yet unimplemented features to automatically schedule hundreds of employees for months of productivity re-education, including preventing employees from scheduling meetings with others if the service deems it counter-productive. So, could the HAL 9000’s “I’m sorry Dave, I’m afraid I can’t do that” be considered prior art?

But Microsoft “has even bigger ideas for using technology to monitor workers in the interest of maximizing organizational productivity,” reports GeekWire:
Newly surfaced Microsoft patent filings describe a system for deriving and predicting “overall quality scores” for meetings using data such as body language, facial expressions, room temperature, time of day, and number of people in the meeting. The system uses cameras, sensors, and software tools to determine, for example, “how much a participant contributes to a meeting vs performing other tasks (e.g., texting, checking email, browsing the Internet).”

The “meeting insight computing system” would then predict the likelihood that a group will hold a high-quality meeting. It would flag potential challenges when an organizer is setting the meeting up, and recommend alternative venues, times, or people to include in the meeting, for example… A patent application made public Nov. 12 notes, “many organizations are plagued by overly long, poorly attended, and recurring meetings that could be modified and/or avoided if more information regarding meeting quality was available.” The approach would apply to in-person and virtual meetings, and hybrids of the two…

The filings do not detail any potential privacy safeguards. A Microsoft spokesperson declined to comment on the patent filings in response to GeekWire’s inquiry. To be sure, patents are not products, and there’s no sign yet that Microsoft plans to roll out this hypothetical system. Microsoft has established an internal artificial intelligence ethics office and a companywide committee to ensure that its AI products live by its principles of responsible AI, including transparency and privacy. However, the filings are a window into the ideas floating around inside Microsoft, and they’re consistent with the direction the company is already heading.
