Nice Rocket

Revenge porn is a horrible thing, and Twitter should definitely continue to ban anyone who attempts to post it on the app. That being said, a video of a rocket taking off — an actual rocket, you pervs — does not revenge porn make, and shouldn't be flagged as such.

It seems like a silly thing to have to say, but such is the exact situation that spaceflight photographer John Kraus found himself in earlier this week. Kraus, who was on site to photograph the historic Artemis I launch, took to Twitter to post a mesmerizing video of the liftoff — only to find himself kicked off of the app shortly thereafter, due to the fact that his post, for whatever inexplicable reason, had been marked as revenge porn.

"I’d like to acknowledge that our good friend and rocket photography extraordinaire, [John Kraus], has been completely locked out of twitter since yesterday, for an arbitrary and silly reason, the day of the biggest launch of his career," read an angry tweet from the Tim "Everyday Astronaut" Dodd. "Worst possible timing."

Let Freedom Ring

Twitter finally let Kraus back online today. But for a rocket photographer, getting kicked off of Twitter on the day of the Artemis I launch really is a nightmare scenario.

"Almost two days later, I'm back. Twitter just acknowledged that they falsely locked my account instantly after I posted a benign video/caption of the Artemis I launch," he tweeted upon his return. "This was an unfortunate error after one of the biggest launches of my career."

While there was some speculation that new Twitter owner Elon Musk — who fired waves of employees, then effectively forced a mass exodus of quitters, and has reportedly been begging employees to come back so the ship that is Twitter doesn't fully sink beneath the digital waves — was to blame for Kraus' unfortunately-timed ban, given the chaos that's ensued on the tech side since Musk's takeover. Kraus, however, denied that Musk had anything to do with it.

"Anyone speculating it had to do with [Elon Musk] / new Twitter policy / not wanting NASA content instead of SpaceX, or that it was an ITAR violation — you are WRONG," he clarified. "It was falsely auto-flagged by software/AI."

So, maybe not Musk's fault, but a screwup that now falls directly on his presumably still-full plate. Anyway. We're glad that Kraus is free. And, for the record, here's the video that led to the whole debacle:

For reference, this was the original, exact tweet that got my account falsely locked for almost two days. It is now visible. Enjoy! https://t.co/Rpnaqfw6yX

No Photos, Please

NASA barred the press from photographing the launch site of its Space Launch System after it boosted the agency's Artemis I Moon mission into space earlier this week.

Multiple space reporters said on Twitter that the agency had sent them a message telling them they were prohibited from photographing the Artemis 1 launch tower after the liftoff.

"NASA did not provide a reason," Eric Berger, Ars Technica's senior space editor, tweeted. The reporter added that according to his sources, the ban was apparently an attempt to save face after the launch damaged the tower.

"So now sources are saying that yes, Launch Complex-39B tower was damaged during the Artemis I launch on Wednesday morning," Berger tweeted. "Basically, there were leaks and damage where there weren't supposed to be leaks and damage."

Damaging Reports

Later, Washington Post space reporter Christian Davenport posted a statement from NASA that seemed to corroborate Berger's sources, though he emphasized that there was "no word on damage" to the launch pad.

"Because of the current state of the configuration, there are [International Traffic in Arms Regulations license] restrictions and photos are not permitted at this time," the statement given to Davenport read. "There also is a launch debris around the pad as anticipated, and the team is currently assessing."

Whatever NASA's reasoning, it's pretty clear that the agency doesn't want unapproved photos of its expensive and overdue Space Launch System rocket going out to the public. NASA loves positive publicity, it seems — but not negative.

Worst Case Scenario

Elon Musk's Twitter-buying experiment is somehow going even worse than expected, amid reports that he's locked employees out of the company's office buildings.

As reported by Platformer's Zoë Schiffer, an email sent to Twitter staff yesterday evening informed them out of the blue that they wouldn't be able to get into their offices for the rest of the week.

"We're hearing this is because Elon Musk and his team are terrified employees are going to sabotage the company," Schiffer wrote. "Also, they're still trying to figure out which Twitter workers they need to cut access for."

Then, the saga somehow got even stranger today when Musk emailed staff asking them to come to the 10th floor of Twitter's headquarters — which, remember, they'd just been told they were locked out of — for a meeting on the 10th floor.

Ultimatums

All told, the aura of chaos surrounding Twitter since Musk's acquisition late last month has deepened to a comical degree.

News of the office closure, you'll recall, comes not long after Musk issued an ultimatum to the staff who survived his first purge the company's employees, in which he said that if "tweeps" didn't come into the office, they would be effectively tendering their resignations.

Just before the office closure announcement, Musk gave his new employees another apparent threat: that if they are not prepared "to be extremely hardcore" and work long in-office hours, they can cut and run with three months severance.

Unsurprisingly, many Twitter employees have chosen the latter — a move that some described to CNN's Darcy as a "mass exodus."

And in the face of all this contradiction and whiplash, who could blame them?

Above all else, FTX advertisements wanted you to know two things: that cryptocurrency is a force for good, and that you don't need to be an expert to buy and trade it. In fact, you don't even have to understand it at all. You just need to get involved, because if you don't, you'll get left behind.

If a bit cheesy then, those same promotions — an array of of television commercials, social media posts, and print ads featuring an impressive lineup of A-list celebrities and athletes, in addition to appearances by the now-bankrupt exchange's ex-CEO Sam Bankman-Fried — are surreal, if not troubling, to watch now, roughly a week after the exchange's spectacular collapse.

Bankman-Fried, widely believed to be the cryptosphere's alleged savior, is under investigation by both the SEC and the CFTC, having lost virtually all his personal wealth in a single day. Meanwhile, an estimated $11 billion's worth of user funds — including that of the retail investors targeted by those shiny ads, many of whom have lost their savings — have vanished. But just six or so months ago? Unretired Buccaneers quarterback Tom Brady was asking people if they were "in"; basketball star Steph Curry coolly told users that, like him, they didn't need to be a crypto "expert" to invest in digital assets; comedian Larry David told retail investors to ignore their crypto-skepticism; supermodel Gisele Bündchen, in a print campaign with Bankman-Fried, promised that she and FTX would save the world.

"The blood's on [Sam Bankman-Fried's] hands," Joseph Kaye, a Partner at the Moskowitz Law Firm in Florida, told Futurism. "And as far as we're concerned, it's on the hands of anybody who has been promoting this product."

Kaye's firm, alongside that of New York's David Boies, is representing thousands of dismayed FTX retail investors in a class action lawsuit filed this week against FTX, its founder, and its many celebrity sponsors, accusing those named of intentionally preying on low-information investors.

Of course, consuming a celebrity endorsement is like breathing air at this point. They're soaked into every corner of the culture, and most every public figure has their influencing hustle — makeup, clothes, shoes, cars, gummies and the like. And sure, a fair share of celebs have inspired rage over, say, Instagram posts touting diet suppressant lollipops.

FTX accounts, however, are a different story. You'd be hard-pressed to find someone who bought a celeb-endorsed lollipop and woke up to find thousands — if not millions — of their savings gone, and a balance sheet marking an eight billion dollar hole to show for it.

Like the now-also-defunct Voyager Digital's Earn Program, FTX accounts were yield-bearing, promising its investors high returns for their investments — so, basically, the markings of a security, just without the actual label. (The Moskowitz firm is also representing plaintiffs in a class action suit brought against Voyager and Mark Cuban, billionaire of "Shark Tank" fame.)

"A lot of people get confused and think that 'oh, well, investing in cryptocurrency is inherently risky,'" Kaye said. "But the issue here is not so much 'did they make an investment in cryptocurrency. It's the function of the account."

And while that's risky enough to begin with, it now appears that FTX — which hasn't officially been charged with anything yet — was using its investors' cash like a piggy bank, funding its own lending activities with the user money with which it'd been trusted.

"When you make statements like [those celebrities did] — and you don't disclose how much you're making or what your arrangement with them is — and it ends up being an unregistered security," Kaye continued, "you're liable as a promoter to the same extent as if you're the FTX exchange."

No one's saying that Brady or Bündchen or anyone else knew that FTX was potentially involved in any malpractice. They were likely taken in by Bankman-Fried's efforts to build a reputation for himself as Mr. Trustworthy Crypto Man, which he admitted shortly after the collapse had largely been a "front." It's also unlikely that they knew, or even really understood, that they were or could be hawking what might just shake out to be an unregistered security.

That's exactly the point, though. We believe, as they told us, that they weren't "experts." Not in the slightest. There doesn't appear to have been much — if any — due diligence here, and a lot of real people have been badly hurt because of it. Did Curry stand on a street corner and hand out FTX accounts? No, but it can be argued that he and the other figures named in the suit played a serious role in FTX's adoption by the masses, downplaying the instability and messiness of the blockchain world while promising that FTX had their back.

And considering how central they may have been to FTX's rise, it would be heartening to see them take some kind of responsibility after its fall.

"I remember our first meeting and we were speaking to the FTX guys… They started to explain it to us and I said, 'I don't know if you can tell over Zoom when our eyes glazed over, but I still don't understand it," David told The Hollywood Reporter back in February, shortly after his Super Bowl commercial aired. "But that's OK. I don't have to know everything.'"

All-Encompassing

The universe is so vast and old that we can't possibly fathom it all. But we can make some pretty admirable efforts.

Take this stunning new map, put together by astronomers at Johns Hopkins University, that displays the entire known universe in all its glory, showcasing some 200,000 galaxies as tiny dots that span all the way to the cosmos' observable limits.

Using data gathered over 20 years by the Sloan Digital Sky Survey, it shows the real positions and colors of the galaxies in a densely packed celestial slice which lets users easily scroll through billions of years.

You've probably seen other maps of the universe before, but likely none this impressive. Excitingly, it uses data previously unreleased to the public, and it might be the most comprehensive cosmic map made for the average Joe yet.

"Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries." said the map's creator and John Hopkins professor Brice Ménard, in a press release.

"But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists," he continued. "Our goal here is to show everybody what the universe really looks like."

Cosmic Cartography

The map's narrowest point originates from our home, the Milky Way, surrounded by light blue dots of spiral galaxies up to two billion light years away from Earth. Further away, yellow briefly takes over, where elliptical galaxies outshine the dimmer spiral ones.

Then the map takes us into a vibrant gradient of red. These are also elliptical galaxies, but thanks to the phenomenon aptly known as redshifting, their yellow light gets stretched into red.

Lurking behind is a tremendous ocean of blue, where the dots represent quasars, the luminous supermassive black holes at the center of distant galaxies.

Even a few errant red dots, depicting redshifted quasars, are speckled across the universe's penultimate boundary that's shrouded in hydrogen gas.

Finally, the map terminates at 13.7 billion light years away, or years ago, where all that can be discerned is the cosmic microwave background.

Stayin' Alive

NASA's astronaut social media handbook just dropped — and they've got some staunch guidelines for space tweeting.

As part of a public records request, NASA released to Vox an almost entirely unredacted copy of its current social media handbook for astronauts, and it offers a fascinating look into the agency's policies for the online astronauts it sends to space.

Overall, it's a reasonable document. One particularly interesting detail? It advises astronauts to please lay off of posting when their lives are in jeopardy. Good advice for us all!

Socialing

In a 2018 memo from the Johnson Space Center included in the records provided to Vox, NASA notes that along with not posting for personal or financial gain or exposing state secrets, "social media efforts should always be considered secondary to the safety of the crew and vehicle."

In another section of the guidelines, a slide reminds astronauts that "social media is voluntary and should be considered secondary to safety of mission and crew cohesion."

Politicking

Beyond bodily safety, political discretion is also repeatedly advised in the guidelines — an important detail, given the past and current tensions between the ISS' main players, the United States and Russia.

While some have criticized NASA for doing a bit too much social networking — the agency operates a whopping 700 social media accounts, including on Reddit, Twitch, and LinkedIn — it clearly takes a backseat to onboard safety.

Given how much can go wrong on both a mortal and interpersonal level while floating above the Earth, that's definitely a good thing.

NASA Tells Astronauts That Tweeting Isn't As Important as Staying Alive

NASA says it can't find any record that James Webb, the State Department and NASA leader for whom the agency's groundbreaking new space telescope is named, was aware of homophobic government purges — but a bunch of astronomers are clapping back at the agency's claims.

"After an exhaustive search of U.S. government and Truman library archives," administrator Bill Nelson was quoted as saying in the agency's press release about its decision, "NASA’s historical investigation found, ‘To date, no available evidence directly links Webb to any actions or follow-up related to the firing of individuals for their sexual orientation.'"

In their own statement — which follows a 2021 Scientific American editorial and numerous other calls urging NASA to rename the telescope — astronomy experts Chanda Prescod-Weinstein, Lucianne Walkowicz, Sarah Tuttle and Brian Nord are calling shenanigans in the strictest terms.

"NASA’s press release utilizes a practice of selective historical reading," the open letter reads, pointing to the agency's insistence that the original Webb was unaware of the firing of Clifford Norton, a NASA budget analyst who was canned in 1963 after being arrested for making a "homosexual advance" on someone. At the time, Webb was head of NASA.

The argument — which makes sense, if you think about it — is basically that Webb was either aware of the institutionalized homophobia in a way that didn't survive in existing documentation, or unaware of a key dynamic at the workplace he was in charge of. Neither option is flattering.

"Because we do not know of a piece of paper that explicitly says, 'James Webb knew about this,' they assume it means he did not," the experts wrote. "In such a scenario, we have to assume he was relatively incompetent as a leader: the administrator of NASA should know if his chief of security is extrajudicially interrogating people."

"We are deeply concerned by the implication that managers are not responsible for homophobia or other forms of discrimination that happens on their watch," they continued, noting that such a stance is "explicitly anti-equity, diversity and inclusion" that puts "responsibility on the most marginalized people to fend for ourselves, and it is in conflict with legal norms in many US jurisdictions."

It's "deeply unscientific," the astronomy luminaries added, that "NASA is engaging in historical cherry picking" with a figure who was, along with the state-sanctioned homophobia that occurred on his watch, accused of engaging in Cold War-era "psychological warfare," in which, as The Atlantic noted in 2018, then-Undersecretary of State Webb assembled a team of hard and soft scientists to figure out the best ways to conduct anti-Soviet propaganda.

NASA and the scientific community at large should, the astronomers wrote in Scientific American, "name telescopes out of love for those who came before us and led the way to freedom."

A provocative manslaughter case is about to kick off in Los Angeles later this month, involving a fatal crash caused by a Tesla vehicle that had the company's controversial Autopilot feature turned on.

It's the first case of its kind, and one that could set a precedent for future crashes involving cars and driver-assistance software, Reuters reports.

We won't know the exact defense until the case gets under way, but the crux is that the man who was behind the wheel of the Tesla is facing manslaughter charges — but has pleaded not guilty, setting up potentially novel legal arguments about culpability in a deadly collision when, technically speaking, it wasn't a human driving the car.

"Who's at fault, man or machine?" asked Edward Walters, an adjunct professor at the Georgetown University, in an interview with Reuters. "The state will have a hard time proving the guilt of the human driver because some parts of the task are being handled by Tesla."

The upcoming trial is about a fatal collision that took place in 2019. The crash involved Kevin George Aziz Riad, who ran a red light in his Tesla Model S, and collided with a Honda Civic, killing a couple who were reportedly on their first date.

According to vehicle data, Riad did not apply the brakes but had a hand on the steering wheel. Perhaps most critically, though, the Tesla's Autopilot feature was turned on in the moments leading up to the crash.

Riad is facing manslaughter charges, with prosecutors arguing his actions were reckless.

Meanwhile, Riad's lawyers have argued that he shouldn't be charged with a crime, but have so far stopped short of publicly placing blame on Tesla's Autopilot software.

Tesla is not directly implicated in the upcoming trial and isn't facing charges in the case, according to Reuters.

A separate trial, however, involving the family of one of the deceased is already scheduled for next year — but this time, Tesla is the defendant.

"I can't say that the driver was not at fault, but the Tesla system, Autopilot, and Tesla spokespeople encourage drivers to be less attentive," the family's attorney Donald Slavik told Reuters.

"Tesla knows people are going to use Autopilot and use it in dangerous situations," he added.

Tesla is already under heavy scrutiny over its Autopilot and so-called Full Self-Driving software, despite conceding that the features "do not make the vehicle autonomous" and that drivers must remain attentive of the road at all times.

Critics argue that Tesla's marketing is misleading and that it's only leading to more accidents — not making the roads safer, as Tesla CEO Elon Musk has argued in the past.

In fact, a recent survey found that 42 percent of Tesla Autopilot said they feel "comfortable treating their vehicles as fully self-driving."

Regulators are certainly already paying attention. The news comes a week after Reuters revealed that the Department of Justice is investigating Tesla over Autopilot.

Last year, the National Highway Traffic Safety Administration (NHTSA) announced an investigation of accidents in which Teslas have smashed into emergency response vehicles that were pulled over with sirens or flares.

This month's trial certainly stands the chance of setting a precedent. Was Riad fully at fault or was Tesla's Autopilot at least partially to blame as well?

The answer now lies in the hands of a jury.

Core Dump

Scientists studying a group of stars made an astonishing but "serendipitous" discovery when they realized that Gamma Columbae, a fairly average celestial body, might actually be the "stripped pulsating core of a massive star," according to a study published this week in Nature Astronomy.

If true, that means Gamma Columbae is missing the envelope, or vast shroud of gas, that hides a star's nuclear fusion powered core.

What caused the stripping of this atmospheric envelope is not definitively known, but the scientists posit that Gamma Columbae running out of hydrogen could've caused its envelope to expand and swallow up a nearby star, likely its binary partner. But in the middle of that relatively common process, something appears to have horrifically gone wrong and ejected the envelope — and possibly even led to the two stars merging.

Naked Core

Before the disaster, the scientists believe Gamma Columbae could have been up to 12 times the mass of our Sun. Now, it's a comparatively meager 5 stellar masses.

Although a naked stellar core missing its envelope has been theorized to exist, it's never been observed in a star this size.

"Having a naked stellar core of such a mass is unique so far," said study co-author Norbert Pryzbilla, head of the Institute for Astro- and Particle Physics at the University of Innsbruck, in an interview with Vice.

Astronomers had an idea of what the cores of massive and low mass stars looked like, Pryzbilla continued, but there wasn't "much evidence" for cores of masses in between.

Star Power

It's an exceedingly rare find because the star is in a "a short-lived post-stripping structural re-adjustment phase" that will only last 10,000 years, according to the study.

That's "long for us humans but in astronomical timescales, very, very short," Przybilla told Vice. "It will always stay as a peculiar object."

The opportunity to study such a rarely exposed stellar core could provide scientists an invaluable look into the evolution of binary star systems. And whatever astronomers learn from the star, it's a fascinating glimpse at stellar destruction at a nearly incomprehensible scale.

Fill 'Er Up

A team of Chinese researchers say they managed to convert actual lunar regolith samples into a source of rocket fuel and oxygen — a potential gamechanger for future space explorers hoping to make use of in-situ resources to fuel up for their return journey.

The researchers found that the lunar soil samples can act as a catalyst to convert carbon dioxide and water from astronauts' bodies and environment into methane and oxygen, as detailed in a paper published in the National Science Review.

"In situ resource utilization of lunar soil to achieve extraterrestrial fuel and oxygen production is vital for the human to carry out Moon exploitation missions," lead author Yujie Xiong said in a new statement about the work. "Considering that there are limited human resources at extraterrestrial sites, we proposed to employ the robotic system to perform the whole electrocatalytic CO2 conversion system setup."

That means we could have a much better shot at carrying out longer duration explorations of the lunar surface in the near future.

Set It, Forget It

According to the paper, which builds on previous research suggesting lunar soil can generate oxygen and fuel, this process can be completed using uncrewed systems, even in the absence of astronauts.

In an experiment, the team used samples from China's Chang'e-5 mission, which landed in Inner Mongolia back in December 2020 — the first lunar soil returned to Earth since 1976.

The Moon soil effectively acted as a catalyst, enabling the electrocatalytic conversion of carbon dioxide into methane and oxygen.

"No significant difference can be observed between the manned and unmanned systems, which further suggests the high possibility of imitating our proposed system in extraterrestrial sites and proves the feasibility of further optimizing catalyst recipes on the Moon," the researchers conclude in their paper.

Liquified

But there's one big hurdle to still overcome: liquifying carbon dioxide is anything but easy given the Moon's frosty atmosphere, as condensing the gas requires a significant amount of heat, as New Scientist reported earlier this year.

Still, it's a tantalizing prospect: an autonomous machine chugging away, pumping out oxygen and fuel for future visitors. But for now, it's not much more than a proof of concept.

Now that Tesla CEO Elon Musk has taken over Twitter, the billionaire has been frantically shuffling through ambitious plans to turn the ailing social media platform into a revenue-driving business.

Case in point, according to internal email obtained by The Washington Post, Musk is plotting for Twitter to charge users to view videos posted by content creators and take a cut of the proceeds — a highly controversial idea that's already been met with internal skepticism.

The team of Twitter engineers has "identified the risk as high" in the email, citing "risks related to copyrighted content, creator/user trust issues, and legal compliance."

In short, Musk is blazing ahead with his infamously ambitious timelines — a "move fast and break things" approach that could signify a tidal change for Twitter's historically sluggish approach to launching new features.

Musk has already made some big structural changes to Twitter, having fired high-up positions at the company and dissolved its board of directors.

The company will also likely be facing mass layoffs, according to The Washington Post.

The new feature detailed in the new email, which is being referred to as "Paywalled Video," allows creators to "enable the paywall once a video has been added to the tweet" and chose from a preset list of prices, ranging from $1 to $10.

"This will also give Twitter a revenue stream to reward content creators," Musk tweeted on Tuesday, adding that "creators need to make a living!"

But whether Twitter users will be willing to pay for stuff that was previously free remains anything but certain.

Musk has already announced that he is planning to charge $8 a month for Twitter users to stay verified, which has been met with derision.

The billionaire CEO is facing an uphill battle. Now that the company is private, he has to pay around $1 billion in annual interest payments, a result from his $44 buyout, according to the WaPo.

Compounding the trouble, Reuters reported last week that Twitter is bleeding some of its most active users.

Meanwhile, Musk's chaotic moves are likely to alienate advertisers, with the Interpublic Group, a massive inter-agency advertising group, recommending that its clients suspend all paid advertising for at least the week.

That doesn't bode well. It's not out of the question that a paywalled video feature may facilitate the monetization of pornographic content, which may end up scaring off advertisers even further — but Twitter's exact intentions for the feature are still unclear.

According to Reuters, around 13 percent of the site's content is currently marked not safe for work (NSFW).

It's part of Musk's attempt to shift revenue away from advertising on the platform. In a tweet last week, he promised advertisers that Twitter wouldn't become a "free-for-all hellscape."

But that hasn't stopped advertisers from already leaving in droves.

All in all, a paywalled video feature could mark a significant departure for Twitter, a platform still primarily known for short snippets of text.

For now, all we can do is watch.

COP Out

Ever since she lambasted world leaders at a UN conference in 2018 when she was only 15 years old, Swedish environmental activist Greta Thunberg has had the ear of the international community.

Now, Thunberg says she's skipping out on next week's COP27 UN climate summit in Egypt. Why? Because it's rife with "greenwashing."

"I'm not going to COP27 for many reasons, but the space for civil society this year is extremely limited," Thunberg said at a press event for her book, "The Climate Book," as quoted by The Guardian. "The COPs are mainly used as an opportunity for leaders and people in power to get attention, using many different kinds of greenwashing."

Ultimately, in Thunberg's view, the COP conferences "are not really meant to change the whole system" and instead only promote incremental change. Bluntly put, they're feel-good events that don't accomplish much, so she's bowing out.

Wasted Breath

It's not an unfair assessment. For all the pledges made to drastically cut back emissions and achieve net carbon zero by 2050, very few nations have followed through in the short term. And in Europe, the energy crisis in the wake of the war in Ukraine has further sidelined those climate commitments.

So we can't blame her for not going. But it's a bit disheartening that even a tenacious young spokesperson like Thunberg has given up on convincing world leaders at the biggest climate summit in the world.

Maybe it's indicative of the frustrations of her generation at large. When Thunberg was asked what she thought about the recent wave of Just Stop Oil protests that included activists throwing soup on a Van Gogh painting, she said that she viewed what many detractors perceived as a dumb stunt to be symptomatic of the world's failure to effect meaningful environmental change.

"People are trying to find new methods because we realize that what we have been doing up until now has not done the trick," she replied, as quoted by Reuters. "It's only reasonable to expect these kinds of different actions."

Maybe the real question is: if even a UN climate conference isn't the place to get the message out and change hearts, where's the right place, and what's the right way? If the headlines are any indication, zoomers are struggling to figure that out.

Greta Thunberg Says UN Climate Conference Is a Scam and She's Not Attending

Astronomers are puzzled by the strange behavior of certain crooked clusters of stars, which appear to be violating our conventional understanding of gravity.

Massive clusters of stars usually are bound together in spirals at the center of galaxies. Some of these clusters fall under a category astrophysicists call open star clusters, which are created in a relatively short period of time as they ignite in a huge cloud of gas.

During this process, loose stars accumulate in a pair of "tidal tails," one of which is being pulled behind, while the other moves ahead.

"According to Newton’s laws of gravity, it’s a matter of chance in which of the tails a lost star ends up," Jan Pflamm-Altenburg of the University of Bonn in Germany, co-author of a new paper published in the Monthly Notices of the Royal Astronomical Society, in a statement. "So both tails should contain about the same number of stars."

But some of their recent observations seemingly defy conventional physics.

"However, in our work we were able to prove for the first time that this is not true," Pflamm-Altenburg added. "In the clusters we studied, the front tail always contains significantly more stars nearby to the cluster than the rear tail."

In fact, their new findings are far more in line with a different theory called "Modified Newtonian Dynamics" (MOND).

"Put simply, according to MOND, stars can leave a cluster through two different doors," Pavel Kroupa, Pflamm-Altenburg's colleague at the University of Bonn and lead author, explained in the statement. "One leads to the rear tidal tail, the other to the front."

"However, the first is much narrower than the second — so it’s less likely that a star will leave the cluster through it," he added. "Newton’s theory of gravity, on the other hand, predicts that both doors should be the same width."

The researchers' simulations, taking MOND into consideration, could explain a lot. For one, they suggest that open star clusters survive a much shorter period of time than what is expected from Newton's laws of physics.

"This explains a mystery that has been known for a long time," Kroupa explained. "Namely, star clusters in nearby galaxies seem to be disappearing faster than they should."

But not everybody agrees that Newton's laws should be replaced with MOND, something that could shake the foundations of physics.

"It’s somewhat promising, but it does not provide completely definitive evidence for MOND," University of Saint Andrews research fellow Indranil Banik told New Scientist. "This asymmetry does make more sense in MOND, but in any individual cluster there could be other effects that are causing it — it’s a bit unlikely that would happen in all of them, though."

The researchers are now trying to hone in on an even more accurate picture by stepping up the accuracy of their simulations, which could either support their MOND theory — or conclude that Newton was, in fact, correct the first time around.

Rock of Riches

After disappointing setbacks and a delay over the summer, NASA says it's finally reviving its mission to explore a tantalizing and giant space rock lurking deep in the Asteroid Belt.

Known as 16 Psyche, the NASA-targeted asteroid comprises a full one percent of the mass of the Asteroid Bet, and is speculated to be the core of an ancient planet. But Psyche's size isn't what intrigues scientists so much as its metal-rich composition, believed to be harboring a wealth of iron, nickel, and gold worth an estimated $10 quintillion — easily exceeding the worth of the Earth's entire economy. Although, to be clear, they're not interested in the metals' monetary value but rather its possibly planetary origins.

Back On Track

Initially slated to launch in August 2022, NASA's aptly named Psyche spacecraft became plagued with a persistent flight software issue that led the space agency to miss its launch window that closed on October 11.

But after surviving an independent review determining whether the mission should be scrapped or not, NASA has formally announced that its spacecraft's journey to Psyche will be going ahead, planned to launch aboard a SpaceX Falcon Heavy rocket as early as October 10, 2023.

"I'm extremely proud of the Psyche team," said Laurie Leshin, director of NASA's Jet Propulsion Laboratory, in a statement. "During this review, they have demonstrated significant progress already made toward the future launch date. I am confident in the plan moving forward and excited by the unique and important science this mission will return."

Although the new launch date is only a little over a year late, the expected arrival at the asteroid Psyche is set back by over three years — 2029 instead of 2026 — due to having to wait for another opportunity to slingshot off of Mars' gravity.

Peering Into a Planet

Once it arrives, the NASA spacecraft will orbit around the asteroid and probe it with an array of instruments, including a multispectral imager, gamma ray and neutron spectrometers, and a magnetometer, according to the agency.

In doing so, scientists hope to determine if the asteroid is indeed the core of a nascent planet known as a planetesimal. If it is, it could prove to be an invaluable opportunity to understand the interior of terrestrial planets like our own.

AI-lands in the Stream

Sorry, but not even Dolly Parton is sacred amid the encroachment of AI into art.

Holly Herndon, an avant garde pop musician, has released a cover of Dolly Parton's beloved and frequently covered hit single, "Jolene." Except it's not really Herndon singing, but her digital deepfake twin known as Holly+.

The music video features a 3D avatar of Holly+ frolicking in what looks like a decaying digital world.

And honestly, it's not bad — dare we say, almost kind of good? Herndon's rendition croons with a big, round sound, soaked in reverb and backed by a bouncy, acoustic riff and a chorus of plaintive wailing. And she has a nice voice. Or, well, Holly+ does. Maybe predictably indie-folk, but it's certainly an effective demonstration of AI with a hint of creative flair, or at least effective curation.

Checking the Boxes

But the performance is also a little unsettling. For one, the giant inhales between verses are too long to be real and are almost cajolingly dramatic. The vocals themselves are strangely even and, despite the somber tone affected by the AI, lack Parton's iconic vulnerability.

Overall, it feels like the AI is simply checking the boxes of what makes a good, swooning cover after listening to Jeff Buckley's "Hallelujah" a million times — which, to be fair, is a pretty good starting point.

Still, it'd be remiss to downplay what Herndon has managed to pull off here, and the criticisms mostly reflect the AI's limited capabilities more than her chops as a musician. The AI's seams are likely intentional, if her previous work is anything to go off of.

Either way, if you didn't know you were listening to an AI from the get-go, you'd probably be fooled. And that alone is striking.

The Digital Self

Despite AI's usually ominous implications for art, Herndon views her experiment as a "way for artists to take control of their digital selves," according to a statement on her website.

"Vocal deepfakes are here to stay," Herndon was quoted saying. "A balance needs to be found between protecting artists, and encouraging people to experiment with a new and exciting technology."

Whether Herndon's views are fatalistic or prudently pragmatic remains to be seen. But even if her intentions are meant to be good for artists, it's still worrying that an AI could pull off such a convincing performance.

A team of neuroscientists at the University of Wisconsin claim to have found a way to control how high mice can get on a given amount of cocaine.

And don't worry — while that may sound like a particularly frivolous plot concocted by a team of evil scientists, the goal of the research is well-meaning.

The team, led by University of Wisconsin neuroscientist Santiago Cuesta, was investigating how the gut microbiome can influence how mice and humans react to ingesting the drug.

The research, detailed in a new paper published this week in the journal Cell Host & Microbe, sheds light on a vicious feedback loop that could explain cases of substance abuse disorders — and possibly lay the groundwork for future therapeutic treatments.

In a number of experiments on mice, the researchers found that cocaine was linked to the growth of common gut bacteria, which feed on glycine, a chemical that facilitates basic brain functions.

The lower the levels of glycine in the brain, the more the mice reacted to the cocaine, exhibiting abnormal behaviors.

To test the theory, the scientists injected the mice with a genetically modified amino acid which cannot break down glycine. As a result, the behavior of mice returned to normal levels.

In other words, the amino acid could curb cocaine addiction-like behaviors — at least in animal models.

"The gut bacteria are consuming all of the glycine and the levels are decreasing systemically and in the brain," said Vanessa Sperandio, senior author, and microbiologist from the University of Wisconsin, in a statement. "It seems changing glycine overall is impacting the glutamatergic synapses that make the animals more prone to develop addiction."

It's an unorthodox approach to treating addiction, but could be intriguing — if it works in people, that is.

"Usually, for neuroscience behaviors, people are not thinking about controlling the microbiota, and microbiota studies usually don't measure behaviors, but here we show they’re connected," Cuesta added. "Our microbiome can actually modulate psychiatric or brain-related behaviors."

In short, their research could lead to new ways of treating various psychiatric disorders such as substance use by adjusting the gut microbiome and not making changes to the brain chemistry.

"I think the bridging of these communities is what's going to move the field forward, advancing beyond correlations towards causations for the different types of psychiatric disorders," Sperandio argued.

Advertisers are fleeing Twitter in droves now that Tesla and SpaceX CEO Elon Musk has taken over control.

Ever since officially closing the $44 billion deal, Musk has been busy gutting the company's executive suite and dissolving its board. Senior executives, as well as Twitter's advertising chief Sarah Personette, have departed as well.

After all, Musk has been very clear about his disdain for advertising for years now.

The resulting uncertainty has advertisers spooked — major advertising holding company IPG has already advised clients to pull out temporarily — and the billionaire CEO is in serious damage mode.

Now, Reuters reports, Musk is spending most of this week meeting with advertisers in New York, trying to reassure them that Twitter won't turn into a "free-for-all hellscape."

According to one of Reuters' sources, the meetings have been "very productive" — but plenty of other marketers are far from satisfied.

Advertisers are reportedly grilling Musk over his plans to address the rampant misinformation being spread on the platform, a trend that Musk himself has been actively contributing to since the acquisition.

And if he's succeeding in ameliorating advertisers in private, he's antagonizing them publicly. On Wednesday, Musk posted a poll asking users whether advertisers should support either "freedom of speech," or "political 'correctness'" — a type of false dichotomy that echoes the rhetoric of far-right conspiracy theorists and conservative pundits.

"Those type of provocations are not helping to calm the waters," an unnamed media buyer told Reuters.

Some are going public with the same sentiment.

"Unless Elon hires new leaders committed to keeping this 'free' platform safe from hate speech, it's not a platform brands can/should advertise on," Allie Wassum, global media director for the Nike-owned shoe brand Jordan, wrote in a LinkedIn post.

So far, Musk's plans for the social media platform remain strikingly muddy. In addition to the behind-the-scenes advertising plays, he's also announced that users will have to pay to retain their verification badge, though he's engaged in a comically public negotiation as to what the cost might be.

He's also hinted that previously banned users — former US president Donald Trump chief among them — might eventually get a chance to return, but only once "we have a clear process for doing so, which will take at least a few more weeks."

The move was seen by many as a way to wait out the impending midterm elections. After all, Twitter has played a huge role in disseminating misinformation and swaying elections in the past.

While advertisers are running for the hills, to Musk advertising is clearly only a small part of the picture — even though historically, social giants like Twitter have struggled to diversify their revenue sources much beyond display ads.

Musk nodded to that reality in a vague open letter posted last week.

"Low relevancy ads are spam, but highly relevant ads are actually content!" he wrote in the note, addressed to "Twitter advertisers."

Big picture, Twitter's operations are in free fall right now and Musk has yet to provide advertisers with a cohesive plan to pick up the pieces.

While he's hinted at the creation of a new content moderation council made up of both "people from all viewpoints" and "wildly divergent views," advertisers are clearly going to be thinking twice about continuing their business with Twitter.

With or without advertising, Twitter's finances are reportedly in a very deep hole. The billions of dollars Musk had to borrow to finance his mega acquisition will cost Twitter around $1 billion a year in interest alone.

The company also wasn't anywhere near profitable before Musk took over, losing hundreds of millions of dollars in a single quarter.

Whether that picture will change any time soon is as unclear as ever, especially in the face of a wintry economy.

But, of course, Musk has proved his critics wrong before. So anything's possible.

Cat Burglar

Cats are known for not really minding their own business, getting their furry paws on just about anything they can.

And it turns out, this makes them effective vectors for DNA evidence, according to a study published last month in the journal Forensic Science International: Genetic Supplement Series.

Researchers collaborating with the Victoria Police Forensic Services Department in Australia found detectable human DNA in 80 percent of the samples collected from 20 pet cats, with 70 percent of the samples strong enough that they could be linked to a person of interest in a crime scene investigation.

"Collection of human DNA needs to become very important in crime scene investigations, but there is a lack of data on companion animals such as cats and dogs in their relationship to human DNA transfer," said study lead author Heidi Monkman, a forensic scientist at Flinders University, in a statement.

"These companion animals can be highly relevant in assessing the presence and activities of the inhabitants of the household, or any recent visitors to the scene."

Here Kitty

One possible takeaway is that cats — and other companion pets like dogs — could be harboring DNA that could help solve a case.

The bigger issue, though, is that pets could introduce foreign DNA that muddles a crime scene, possibly leading to an innocent person being implicated. A pet could be carrying the DNA of a complete stranger, or it might bring the DNA of its owner into a crime scene that they had nothing to do with.

Monkman's colleague and co-author of the paper, Maria Goray, is an experienced crime scene investigator and an expert in DNA transfer. She believes their findings could help clear up how pets might tamper a crime scene by carrying outside DNA.

"Are these DNA findings a result of a criminal activity or could they have been transferred and deposited at the scene via a pet?" Goray asked.

It's a question worth asking — especially because innocent people have been jailed off botched DNA science far too often.

Cats May Be Tampering With Crime Scenes, Scientists Say

Chinese scientists are reportedly planning to send monkeys to its new Tiangong space station for experiments that will involve the animals mating and potentially reproducing, the South China Morning Post reports.

It's a fascinating and potentially controversial experiment that could have major implications for our efforts to colonize space: can mammals, let alone humans, successfully reproduce beyond the Earth?

According to the report, the experiment would take place in the station's largest capsule, called Wentian, inside two biological test cabinets that can be expanded.

After examining the behavior of smaller creatures, "some studies involving mice and macaques will be carried out to see how they grow or even reproduce in space," Zhang Lu, a researcher at the Chinese Academy of Sciences in Beijing, said during a speech posted to social media earlier this week, as quoted by the SCMP.

"These experiments will help improve our understanding of an organism’s adaptation to microgravity and other space environments," he added.

Some simpler organisms, including nematodes and Japanese rice fish, have been observed reproducing in space.

But more complex life forms have struggled. In 2014, a Russian experiment to see whether geckos could produce offspring in space failed when all the critters died.

And the failure rate for mammals, so far, has been total. Soviet Union scientists got mice to mate during a space flight in 1979, but none of them gave birth after being returned to Earth.

In other words, getting monkeys to reproduce on board a space station will be anything but easy. For one, just dealing with living creatures in space can pose immense challenges. The astronauts will "need to feed them and deal with the waste," Kehkooi Kee, a professor with the school of medicine at Tsinghua University, told the SCMP.

Then there's the fact that astronauts will have to keep the macaques happy and comfortable, something that experts say will be challenging since long term confinement in the spartan environments of space habitats could cause immense stress for the simians.

And even if astronauts successfully set the mood for the monkeys, the physics of sex in space are predicted to be challenging.

"Firstly, just staying in close contact with each other under zero gravity is hard," Adam Watkins, an associate professor of reproductive physiology at University of Nottingham, wrote in a 2020 open letter highlighted by the SCMP. "Secondly, as astronauts experience lower blood pressure while in space, maintaining erections and arousal are more problematic than here on Earth."

With its new space station in nearly full operation, China isn't shying away from asking some big questions — but whether these experiments will play out as expected is anything but certain.

Spying @ Home

Ever since the COVID-19 pandemic drove a wave of working from home, companies have been relentless in their efforts to digitally police and spy on remote employees by using what's known as "bossware." That's the pejorative name for software that tracks the websites an employee visits, screenshots their computer screens, and even records their faces and voices.

And now, the National Labor Relations Board (NLRB), an agency of the federal government, is looking to intervene.

"Close, constant surveillance and management through electronic means threaten employees' basic ability to exercise their rights," said NLRB general counsel Jennifer Abruzzo, in a Monday memo. "I plan to urge the Board to apply the Act to protect employees, to the greatest extent possible, from intrusive or abusive electronic monitoring and automated management practices."

Undoing Unions

In particular, Abruzzo is worried about how bossware could infringe on workers' rights to unionize. It's not hard to imagine how such invasive surveillance could be used to bust unionization. Even if the technology isn't explicitly deployed to impede organization efforts, the ominous presence of the surveillance on its own can be a looming deterrent, which Abruzzo argues is illegal.

And now is the perfect moment for the NLRB to step in. The use and abuse of worker surveillance tech in general — not just bossware — has been "growing by the minute," Mark Gaston Pearce, executive director of the Workers' Rights Institute at Georgetown Law School, told CBS.

"Employers are embracing technology because technology helps them run a more efficient business," Gaston explained. "… What comes with that is monitoring a lot of things that employers have no business doing."

Overbearing Overlord

In some ways, surveillance tech like bossware can be worse than having a nosy, actual human boss. Generally speaking, in a physical workplace employees have an understanding of how much privacy they have (unless they work at a place like Amazon or Walmart, that is).

But when bossware spies on you, who knows how much information an employer could be gathering — or even when they're looking in. And if it surveils an employee's personal computer, which more often than not contains plenty of personal information that a boss has no business seeing, that's especially invasive.

Which is why Abruzzo is pushing to require employers to disclose exactly how much they're tracking.

It's a stern message from the NLRB, but at the end of the day, it's just a memo. We'll have to wait and see how enforcing it pans out.
