Smartphones, electric vehicles and wind turbines rely on environmentally destructive rare earth mining operations. Harnessing electric fields could make this mining more sustainable

A proponent of the Great Barrington Declaration is comparing rejection of its "natural herd immunity" approach to the pandemic to the rejection of Ignaz Semmelweis and his findings. It's a deceptive comparison beloved of all manner of scientific cranks.

The post The Semmelweis gambit: A red flag for defending bad science and quackery first appeared on Science-Based Medicine.

Between NASA, other space agencies, and the commercial space sector, there are some truly ambitious plans for humanity’s future in space. These plans envision the creation of permanent infrastructure on and around the Moon that will enable a permanent human presence there, complete with research, science, and commercial operations. They also call for the first crewed missions to Mars, followed by the creation of surface habitats that will allow for return visits. These plans present many challenges, ranging from logistical and technical issues to health and human safety.

Another challenge is coordinating operations across the lunar surface with those in orbit and back at Earth, which requires a system of standardized time. In a recent study, a team of NASA researchers developed a new system of lunar time for all lunar assets and those in cis-lunar space. They recommend that this system’s foundation be relativistic time transformations, known more generally as “time dilation.” Such a system will allow for coordination and effective timekeeping on the Moon by addressing discrepancies caused by gravitational potential differences and relative motion.

The study was conducted by Slava G. Turyshev, James G. Williams, Dale H. Boggs, and Ryan S. Park, four research scientists from NASA’s Jet Propulsion Laboratory (JPL). The preprint of their paper, “Relativistic Time Transformations Between the Solar System Barycenter, Earth, and Moon,” recently appeared online and is currently being reviewed for publication in the journal Physical Review D.

Relativistic time transformations (RTT), as predicted by Lorentz Transformations and Einstein’s Special Theory of Relativity (SR), describe how the passage of time slows for the observer as their reference frame accelerates. When Einstein extended SR to account for gravity with his theory of General Relativity (GR), he established how acceleration and gravity are essentially the same and that the flow of time changes depending on the strength of the gravitational field. This presents a challenge for space exploration, where spacecraft operating beyond Earth are subject to acceleration, microgravity, and lower gravity.

As Turyshev told Universe Today via email, RTT will become a major consideration as humans begin operating on the Moon for extended periods of time:

“[RTT] account for how time flows differently depending on gravitational potential and motion. For example, clocks on the Moon tick slightly faster than those on Earth due to the weaker gravitational pull experienced at the Moon’s surface. Though these differences are small—on the order of microseconds per day—they become significant when coordinating space missions, where even a tiny timing error can translate to large positional inaccuracies or communication delays. In space exploration, precise timing is critical. Various time scales serve different roles, depending on the frame of reference.”

In their paper, the team identified three major timescales that come into play. They include:

• Terrestrial Time (TT): this timescale is used for Earth-based systems, representing time at mean sea level with corrections for Earth’s gravitational potential.
• Barycentric Coordinate Time (TCB): the time coordinate in the Barycentric Celestial Reference System (BCRS), centered at the Solar System barycenter. TCB accounts for relativistic effects due to both gravitational potentials and the motion of bodies relative to the barycenter, making it essential for high-precision modeling of celestial mechanics and dynamics.
• Barycentric Dynamical Time (TDB): derived from TCB but adjusted to run at the same average rate as Terrestrial Time (TT), this adjustment prevents a long-term secular drift relative to TT, ensuring that ephemerides remain consistent with Earth-based observations over long periods.

“Relativistic corrections link these time scales, ensuring consistent timekeeping for spacecraft navigation, planetary ephemerides, and communication,” added Turyshev. “Without such corrections, spacecraft trajectories and mission timings would quickly become unreliable, even at relatively short distances.”

NASA’s Artemis Program includes multiple elements operating in cislunar space and on the lunar surface around the south pole region. These include the orbiting Lunar Gateway, multiple Human Landing Systems (HLSs), and the Artemis Base Camp – which will consist of the Lunar Terrain Vehicle (LTV), the Habitable Mobility Platform (HMP), and the Foundation Surface Habitat (FSH). In addition, the ESA plans to create its Moon Village, consisting of multiple transportation, power, and in-situ resource utilization (ISRU) elements.

China and Russia also have plans for a lunar habitat around the Moon’s south pole region, known as the International Lunar Research Station (ILRS). Based on multiple statements, this station could include a surface element (possibly in a lava tube), an orbital element, and other elements similar to the Artemis Base Camp and Moon Village. These will be followed and paralleled by commercial space interests, which could include harvesting, mining, and even tourism. And, of course, these operations must remain in contact with mission control as the Moon orbits the Earth.

As lunar exploration accelerates, says Turyshev, defining a dedicated Lunar Time (LT) scale and a Luni-centric Coordinate Reference System (LCRS) becomes increasingly important. Hence, he and his colleagues developed a TL scale to ensure precise timekeeping for activities on and around the Moon. Their approach involves applying relativistic principles used for Earth and adapting them to the Moon’s environment, including:

1. Weaker gravity on the Moon leads to a faster tick rate for lunar clocks than Earth clocks.
2. The Moon’s motion around Earth and the Sun introduces periodic time variations.
3. Local gravitational anomalies, known as mascons, subtly influence the Moon’s gravitational field and, thus, the flow of time.

“Our results show that lunar time drifts ahead of Earth time by about 56 microseconds per day, with additional periodic variations caused by the Moon’s orbit,” said Turyshev. “These periodic oscillations have an amplitude of around 0.47 microseconds, occurring over a period of approximately 27.55 days.”

To derive these transformations, Turyshev and his team relied on high-precision data from NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, twin satellites that studied the Moon between 2011 and 2021. In addition to mapping the lunar surface, the twin satellites also mapped the Moon’s gravitational field in fine detail. This was combined with measurements made by Lunar Laser Ranging (LLR) experiments, which measure the Earth-Moon distance with millimeter-level precision. Said Turyshev:

“Using this data, we modeled the Moon’s gravitational potential and orbital dynamics, ensuring sub-nanosecond accuracy in the resulting time transformations. Key constants were introduced to describe the transformations, analogous to those used for Earth-based time systems. The most critical of these constraints are:

• LL, which represents the average rate of time transformation between the Moon’s center and its surface, compensating for the combined gravitational and rotational potential at the selenoid level.
• LM, analogous to LB for Earth, compensates for the average rate in time transformation between Barycentric Coordinate Time (TCB) and Lunar Time (TL).
• LH, representing the long-time average of the Moon’s total orbital energy in its motion around the solar system barycenter. It defines the rate difference between TCB and the luni-centric coordinate system time (TCL) and includes contributions from gravitational interactions with the Sun and planets.
• LEM, which represents the long-time average of the Moon’s total orbital energy in its motion around Earth, as observed from the Geocentric Celestial Reference System (GCRS).
• PEM, which accounts for periodic relativistic corrections arising from the Moon’s elliptical orbit and gravitational perturbations by the Sun and planets, resulting in time-dependent oscillations.

“These transformations form the basis of our highly accurate lunar timekeeping system, which is crucial for future mission planning and operations.”

As Turyshev and his colleagues establish in their paper, there are many reasons why creating a unified lunar time system is essential for mission success. These include:

1. Precision Navigation and Landing: With numerous missions targeting the lunar surface, from orbiters to landers and rovers, synchronized timekeeping will ensure precise positioning and reduce the risk of errors during critical mission phases.
2. Seamless Communication: Coordinating activities between Earth, orbiters, and lunar bases requires consistent time synchronization to avoid communication delays and ensure the correct ordering of data transmission.
3. Collaborative Science: A common time standard enables multiple missions—conducted by different space agencies and organizations—to share and compare data accurately, supporting large-scale studies of lunar geology, seismic activity, and gravitational anomalies.
4. Autonomous Operations: As lunar missions grow in complexity and duration, a dedicated lunar time system will allow bases and spacecraft to operate independently from Earth, reducing dependence on Earth-based timekeeping during periods when Earth is not visible. 

New systems of timekeeping are one of many adaptations that humanity must make to become an interplanetary species. A coordinated system of lunar time will become increasingly important as humanity’s presence on the Moon grows and becomes permanent in this century. Similar measures will need to be taken once regular crewed missions to Mars begin, and those efforts have already begun in earnest!

The post If We Want to Live on Other Worlds, We're Going to Need New Clocks appeared first on Universe Today.

I’ve often said that if I could have been any rock star, it would have been Stephen Stills. Well, make that any American rock star, for if I could chose one musician from around the world, it would be Paul McCartney. Both men were incredibly handsome, a prerequisite for my fantasy, but more important, both were immensely talented, able to write great songs, sing wonderfully, and play a number of instruments with dexterity. It’s just that McCartney produce a greater variety of music, and overall better music, than did Stills.

But Stills, who celebrated his 80th birthday on January 3, remains underrated. His greatest years were with Buffalo Springfield, as well as with Crosby, Nash (and somtimes Neil Young), but I will put up a few songs that he wrote and played on his own or with other groups.

First comes one of my favorite Stills songs, “4 + 20,” which did appear on a CS&N album, but is solely the work of Stills. He was indeed 24 when he wrote it, a remarkable achievement for someone that young. I loved it so much that I taught myself to play it back when I played acoustic guitar and did three-finger picking. Wikipedia says this:

Stills stated: “It’s about an 84-year-old poverty stricken man who started and finished with nothing.” However, the lyrics state that the narrator was born 24 years ago, making him about a year younger than Stills was when the song was recorded.

. . . . Stills recorded the song in one take and planned to use it on his upcoming debut solo album, but when his bandmates heard it, they implored him to use it on the Déjà Vu album. He planned to have bandmates David Crosby and Graham Nash sing harmony parts, but they refused. “They told me they wouldn’t touch it,” said Stills. “So it always stood alone.” On the highly-collaborative Déjà Vu album, “4 + 20” stands out as the only song which was both written and performed solo by one member of the band, justified by Crosby who recalled “We just said, ‘It’s too damn good, we’re not touching it.”)

Here he sings and plays it on the Dick Cavett show, and you might recognize Joni Mitchell beside him as well as David Crosby sitting nearby.  The lyrics are slightly different from the recorded version (here), as Stills seems to forget the one line: “And he wasn’t into selling door to door.”

In this part of his life, Stills was also into wearing ponchos.

“Do for the others” is remarkable in that the entire song—all the vocals and instrumentation—was performed by Stills. (he also wrote it). It’s from his first solo album, the 1970 Stephen Stills. All that Wikipedia says about it is this:

“Do For the Others” was written for David Crosby about the death of his girlfriend Christine Hinton.

Below we have the song “It doesn’t matter” from the 1972 Manassas album, by a group in which he shared guitar leads with former Byrd Chris Hillman.  I wanted to put up a live version of another great song from that album, “So begins the task,” but I couldn’t find a live version. You can hear the recorded version here.

The song is clearly about a lost love, and that love is apparently Judy Collins, with whom Stills had a torrid relationship. One site says this:

[Stills] wrote the song about his breakup with Judy Collins; that same lost romance was fodder for “Suite: Judy Blue Eyes” and “You Don’t Have to Cry.” “So Begins the Task” is believed the first song Stills wrote about/for Collins.

“Suite: Judy Blue Eyes” is one of Stills’s best songs, sung on the 1969 album “Crosby, Stills & Nash” (original recording here). But here are CS&N doing it live, and it’s a very good version, showing the harmony that made the group famous (they first sang together at a party at Joni Mitchell’s home in 1968).

Here’s a translation of the Spanish lyrics at the song’s end:

How happy it makes me to think of Cuba,
the smiles of the Caribbean Sea,
Sunny sky has no blood, and how sad that
I’m not able to go
Oh go, oh go go

What a great tribute to Judy!

Finally, Blonde in the Bleachers,” an underrated song by Joni Mitchell from her great 1972 album “For the Roses.” On this song Stills plays the bass and drums.  The two never had a romance, but did work together a few times.  My theory (which is mine) is that Mitchell wrote the song about Stills and his groupies.

The Atlantic has waded into perilous waters by publishing what turns out to be quite a good article about transgender women competing in athletics against biological women. The fact that this liberal and prestigious magazine even writes about the issue is, to me, a good sign: a sign that the issue needs discussing.  And I’m glad to see that the author, staff writer Helen Lewis, concludes with a solution that is virtually identical to mine.

To read her piece, click below, or find it archived here.

Lewis begins by citing recent controversies involving transgender women competing—and winning—against biological women. They include the now well-known story of Lia Thomas, who will swim no more against women, as well as the San Jose State women’s volleyball team, which included what seemed to be a trans woman (they won’t publicly admit it, but most team members do). This story isn’t as well known:

In September, the San Jose State co-captain Brooke Slusser and the associate coach Melissa Batie-Smoose went public with their concerns about their own team’s trans player. “Safety is being taken away from women,” Batie-Smoose later told Fox News. “Fair play is taken away from women.” Both women told Quillette that they believed players and coaches were being pressured not to make a fuss. The next month, Liilii told me, she and her Nevada teammates voted, 16–1, to boycott their next match against San Jose State. The Nevada players were not alone: Teams from Boise State, the University of Wyoming, Southern Utah, and Utah State also forfeited games rather than face the trans player.

 

San Jose State kept competing despite all that—and despite a lawsuit aimed at barring the school from the Mountain West Conference postseason tournament in Las Vegas in November. (The lawsuit failed, and the team finished second in the finals.) The season ended in acrimony. “I will not sugarcoat our reality for the last two months,” San Jose State’s head coach, Todd Kress, said in a statement after the tournament. “Each forfeiture announcement unleashed appalling, hateful messages individuals chose to send directly to our student-athletes, our coaching staff, and many associated with our program.” Afterward, seven of the team’s athletes requested to enter the transfer portal. The disputed player, who is a senior, will not compete again.

 

The problem is, as the references below show, trans women who go through male puberty retain substantial athletic advantages over biological women, even if testosterone suppressors are used to try to equalize the categories.  But the suppressors don’t do that, for somebody who goes through male puberty develops the musculature, bone density, grip strength, and other indices of athletic success that give them pronounced advantages over natal women (equestrian sports may be an exception).  And this advantage appears to last for years—perhaps forever.

Well, why not allow trans women to compete who have transitioned before puberty? The problem is that there are almost none of these, for male puberty occurs some time between ages 9 and 14, and that is simply too young for adolescent males to decide to take hormones and/or have surgery to develop something closer to a woman’s body. If future research shows that transitioning at a very young age makes females athletically equal on average to natal females, then we can reassess. But existing data show that trans women, or some with disorders of sex determination, have an innate athletic advantage over women, and thus shouldn’t be competing in women’s sports.

Republicans have made hay of this, of course, and if you polled Democrats versus Republicans over whether trans women should compete against natal women in sports, Republicans would say “no” at a higher rate. But just because this view is more pervasive in the GOP doesn’t mean it’s wrong. In fact, Democrats themselves are starting to realize that such competition is unfair:

Greater awareness of Thomas and other trans athletes in women’s sports did not translate into greater approval. If anything, the opposite occurred: In 2021, 55 percent of Democrats supported transgender athletes competing in the team of their chosen gender, according to Gallup. Two years later, however, that number had fallen to 47 percent. Overall, nearly seven out of 10 Americans now think athletes should compete in the category of their birth sex.

Nevertheless, the Biden Administration’s early executive order prohibiting discrimination on the basis of gender identity implied that this would also hold for sports participation. Now, as Lewis notes, Biden has backed off on this construal of the order, perhaps because the wokeness of Harris and Biden (the subject of GOP attack ads) may have played a role in their November defeat.

Regardless, as I’ve learned in the past week or so, those who say that “trans women are women” will accept no exceptions to that mantra: trans women are to have every perquisite of natal women, including sports participation.  But, unlike gay rights, trans rights conflict with the rights of other groups far more often (I can’t think of any case in which gay rights conflict with other people’s rights, except for those cases of religious people asked to make cakes for gay weddings). The last sentence in Lewis’s paragraph below is telling (I’ve bolded it):

“People like to say that it’s a complicated issue, and I don’t actually think it is … It all boils down to: Do you actually think that trans women and intersex women are real women—and are really female or not?” the transgender cyclist Veronica Ivy told The Daily Show’s Trevor Noah in 2022. “It’s an extreme indignity to say, ‘I believe you’re a woman, except for sport.’” She added that the enforcement of traditional categories was about “protecting the fragile, weak cis white woman from the rest of us.” Noah’s studio audience in New York heartily applauded Ivy’s words. Sports was only one part of a seamless whole: If you believed, as good liberals did, that trans women were women, no carve-outs were justifiable.

Many women and men think otherwise, as do I. But the carve-outs, as I see them, are very few. Still, if you’re a extremist gender ideologue, they are impermissible.

Democrat Seth Moulton’s breaking ranks from the Biden-ish gender ideology may have been a telling moment, as it made it acceptable for Democrats to discuss the issue in public, though many, including the FFRF, appear to still think the issue shouldn’t be discussed, much less raised. Moulton still got savaged, of course, which reflects poorly on his fellow Democrats:

After the 2024 election, a handful of Democrats broke ranks. “I have two little girls,” Representative Seth Moulton of Massachusetts told The New York Times. “I don’t want them getting run over on a playing field by a male or formerly male athlete.” His campaign manager subsequently resigned, protesters gathered outside one of his offices, and he was rebuked by the state’s Democratic governor. But many of Moulton’s fellow Democrats were notably silent. “Asked for comment on Mr. Moulton’s remarks, each of the 10 other members of the state’s congressional delegation, all Democrats, declined to comment or did not immediately respond,” the Times reported. Further evidence that a taboo had been broken came on the Friday before Christmas. The White House abandoned its proposed rule change forbidding blanket bans on trans athletes after 150,000 public responses, acknowledging that the incoming Trump administration will set its own rules.

Lewis is too good a writer not to give her own opinion after weighing the controversy. At the end, she suggests the “empathic compromise” given below, and I must say that I agree with almost every word of it:

In my view, the way forward lies in an empathetic compromise, one that broadly respects transgender Americans’ sense of their own identity—for example, in the use of chosen names and pronouns—while acknowledging that in some areas, biology really matters. Many sports organizations have established a protected female category, reserved for those who have not experienced the advantages conferred by male puberty, alongside an open one available to men, trans women, trans men taking testosterone supplements, and nonbinary athletes of either sex. Unlike Veronica Ivy, many voters who support laws protecting trans people from housing and employment discrimination don’t see trans rights as an all-or-nothing deal; in fact, a few limited carve-outs on the basis of biological sex might increase acceptance of gender-nonconforming people overall.

Not everything has to be an entrenched battle of red versus blue: As more and more Democrats realize that they shouldn’t have built their defense of trans people on the sand of sex denialism, Republicans should have the grace to take the win on sports and disown the inflammatory rhetoric of agitators such as Representative Nancy Mace, who responded to the election of the first trans member of Congress by deploying anti-trans slurs. As the second Trump administration begins, the lesson from the college-volleyball rebellion is that institutions cannot impose progressive values by fiat. Attempts at social change will not survive without the underlying work of persuasion.

My only beef with the above is that it may be dangerous to trans men or “nonbinary athletes of either sex” to compete against biological men, as the greater strength of the latter could be dangerous. This is probably why World Rugby, as well as the International Rugby League, have banned the participation of transgender women in international competitions, presumably because although they are biological men, suppressing testosterone could reduce their ability to withstand injury in this heavy-contact sport.

The athletic effects of testosterone suppression in males:

An opinion piece by Robyn Blumner in Skeptical Inquirer cites references I’ve mentioned before, showing that testosterone suppression isn’t a way to equalize the athletic performance of transgender women and natal women. As she writes:

If we eliminated sex categories for most sports, there would rarely be female winners. For natal women to be able to compete in a way that gives them a fair chance at victories, there have to be sex segregated sports.

The question then becomes whether that advantage can be mitigated through testosterone suppression. That is a matter of scientific inquiry, and the longitudinal biomedical findings to date suggest that “the effects of testosterone suppression in male adulthood have very little impact” on physiological outcomes such as muscle strength, muscle mass, or lean body mass, according to a paper titled “When Ideology Trumps Science” by six international leading researchers (Devine et al. 2022). They cite a cross-sectional study from 2022 that measured the performance of transgender women and found the “advantage may be maintained after 14 years of testosterone suppression.” (For a thorough vetting of the subject, read “Transgender Women in the Female Category of Sport: Perspectives on Testosterone Suppression and Performance Advantage” by researchers Emma Hilton and Tommy Lundberg, published in the journal Sports Medicine [Hilton and Lundberg 2021].)

*I applaud Jonathan Haidt for his battle against cellphones in schools, and at The Free Press Olivia Reingold tells us “How Jonathan Haidt won the fight against smartphones in schools” (article archived here).

This past fall, the Seaside School District became one of the first in Oregon to ban cell phones for both middle and high schoolers, forcing kids to lock their devices in pouches near the school entrance until the end of the day. Seaside has joined thousands of schools nationwide in recently banning smartphones, as a growing body of evidence shows they’re linked to falling test scores and rising rates of teen mental illness. This January, just over two million students will return to phone-free schools as statewide bans go into effect in Virginia and South Carolina. The following month, the Los Angeles Unified School District, the second-largest in the nation, will join them.

. . . So why is this movement finally getting results now? I spoke to a dozen people—educators and activists and parents—and they all offered the same answer: Jonathan Haidt.

In March, the New York University social psychologist, who has studied the negative effects of phones on kids for years, published a book called The Anxious Generation, which immediately became a No. 1 New York Times bestseller. It has remained on the list ever since, thanks to a range of influential boosters on both sides of the political aisle. It’s impossible to think of another book that’s been equally celebrated by both Democrats and Republicans: Barack Obama recently named Haidt’s book one of his favorites of the year, while Sarah Huckabee Sanders, the GOP governor of Arkansas, posted an Instagram video of herself with Haidt, promoting his message to her 885,000 followers. Even Bill Gates, who helped wire America by co-founding Microsoft, has listed The Anxious Generation as one of his top four reads of 2024.

Cookbook author Jessica Seinfeld, who has three children with her husband, comedian Jerry Seinfeld, was one of Haidt’s earliest and most vocal online advocates. She told me Haidt’s book “came along at just the right time”—when the negative effects of the Covid-era reliance on screen learning were being widely reported. Even The New York Times, which encouraged social restrictions during the pandemic, is now finally acknowledging that school closures damaged an entire generation.

“We have the first generation of kids who are native to phones and social media,” Seinfeld said, and “the addiction got really real” during Covid. “I can’t tell you how many moms have come up to me and said, ‘My kids hate me because I won’t let them get a phone, and I’m the only one.’ ”

Part of the book’s power is its simplicity. Haidt spells out four “foundational rules” to inspire a “Great Rewiring of Childhood.” They are: no smartphones before high school, no social media before age 16, no phones at school, and more unsupervised play and independence for kids. Haidt has consistently repeated these talking points at talks around the country and on his Instagram page, where he has 341,000 followers.

Even so, Haidt told me he is “astounded” by how quickly the movement has spread throughout America, even rippling across the pond to the UK. “The only other example of social change I’ve seen that has moved this quickly is the fall of the Iron Curtain,” he told me. When I asked him why it took so long, he called it a “collective action problem,” in which the general public resents the status quo, but individuals are too scared to challenge it.

The man should get a damn medal for what he did! Imagine the changes (or rather reversion to the “good old days”) that will happen when phones are widely banned from schools. People will talk to each other!

*The NYT answers the nagging question, “Could monkeys really type all of Shakespeare?” (archived here). You might already have guessed that the answer is “no” unless time is infinite. But time is not infinite.

A new paper by Stephen Woodcock, a mathematician at the University of Technology Sydney, suggests that those efforts may have been for naught: It concludes that there is simply not enough time until the universe expires for a defined number of hypothetical primates to produce a faithful reproduction of “Curious George,” let alone “King Lear.” Don’t worry, scientists believe that we still have googol years — 10¹⁰⁰, or 1 followed by 100 zeros — until the lights go out. But when the end does come, the typing monkeys will have made no more progress than their counterparts at the Paignton Zoo, according to Dr. Woodcock.

“It’s not happening,” Dr. Woodcock said in an interview. The odds of a monkey typing out the first word of Hamlet’s famous “To be or not to be” soliloquy on a 30-key keyboard was 1 in 900, he said. Not bad, one could argue — but every new letter offers 29 fresh opportunities for error. The chances of a monkey spelling out “banana” are “approximately 1 in 22 billion,” Dr. Woodcock said.

The idea for the paper came to Dr. Woodcock during a lunchtime discussion with Jay Falletta, a water-usage researcher at the University of Technology Sydney. The two were working on a project about washing machines, which strain Australia’s extremely limited water resources. They were “a little bit bored” by the task, Dr. Woodcock acknowledged. (Mr. Falletta is a co-author on the new paper.)

If resources for washing clothes are limited, why shouldn’t typing monkeys be similarly constrained? By neglecting to impose a time or monkey limit on the experiment, the infinite monkey theorem essentially contains its own cheat code. Dr. Woodcock, on the other hand, opted for a semblance of reality — or as much reality as a scenario featuring monkeys trying to write in iambic pentameter would allow — in order to say something about the interplay of order and chaos in the real world.

Even if the life span of the universe were extended billions of times, the monkeys would still not accomplish the task, the researchers concluded. Their paper calls the infinite monkey theorem “misleading” in its fundamental assumptions. It is a fitting conclusion, perhaps, for a moment when human ingenuity seems to be crashing hard against natural constraints.

*Glory be! According to the WSJ and many other sites, the U.S. has agreed to sell a lot of weapons to Israel (archived here).

The Biden administration notified Congress of an $8 billion weapons package for Israel, including thousands of bombs, missiles and artillery shells, in one of the largest new arms sales since the war in Gaza began in 2023.

The weapons package, which congressional officials received notification of late on Friday afternoon, also includes the planned sale of thousands of bombs, air-to-air missiles and precision munitions, according to U.S. officials familiar with the sale.

The new weapons package includes some items that could draw objections from Democrats who have opposed the transfer of large bombs to Israel amid concerns over the civilian toll of the war in Gaza. The proposed sale includes a set of guidance kits designed to be fitted to large MK-84 2,000-pound bombs, as well as BLU-109 bunker buster bombs, one of the officials said. Also included are AMRAAM and Hellfire missiles and 155mm artillery rounds.

The planned weapons sale, which comes just weeks before President Biden hands over power to President-elect Donald Trump, is the largest the U.S. government has authorized for Israel since the massive $20 billion weapons package the administration approved in August. Israel was also informed of the move, said an Israeli official, who said that the country expected the weapons to begin arriving in 2025.

“We will continue to provide the capabilities necessary for Israel’s defense,” said an administration official familiar with the deal, which still requires congressional approval to move forward. The office of Israeli Prime Minister Benjamin Netanyahu declined to comment. The new weapons package was reported earlier by Axios.

Arms sales to Israel have been a troublesome issue for the Biden administration, which organized an airlift of bombs and other munitions to Israel in the aftermath of Hamas’s Oct. 7, 2023 attack on southern Israel, in which about 1,200 people were killed and militants seized some 250 hostages.

Given that Israel is at war with seven countries or territories (Iran, Syria, Lebanon, Gaza, Yemen, and likely Syria, not to mention militia in Iraq), and that Israel has the $8 billion (its economy is doing well), this is a well-timed benefit for Israel, and Yahweh knows they need it.

*Joe Biden is trying to leave a “green” legacy, and has done something good to further it, just prohibiting oil drilling under a huge amount of federally-owned waters (archived here). But will Trump manage to overrule it? It doesn’t look like it.

President Joe Biden will move Monday to block all future oil and gas drilling across more than 625 million acres of federal waters — equivalent to nearly a quarter of the total land area of the United States, according to two people briefed on the decision who spoke on the condition of anonymity because the announcement is not yet public.

The action underscores how Biden is racing to cement his legacy on climate change and conservation in his last weeks in office. President-elect Donald Trump, who has described his energy policy as “drill, baby, drill,” is likely to work with congressional Republicans to challenge the decision.

Biden will issue two memorandums that prohibit future federal oil and gas leasing across large swaths of the Atlantic Ocean, the Pacific Ocean, the eastern Gulf of Mexico and the Northern Bering Sea in Alaska, the two people said. The oil and gas industry has long prized the eastern Gulf of Mexico in particular, viewing the area as a key part of its offshore production plans.

Some details of the expected decision were first reported by Bloomberg News. The total acreage and the inclusion of the Northern Bering Sea have not previously been reported.

The White House did not immediately respond to a request for comment.

Karoline Leavitt, a spokeswoman for the Trump transition team, said in an email: “This is a disgraceful decision designed to exact political revenge on the American people who gave President Trump a mandate to increase drilling and lower gas prices. Rest assured, Joe Biden will fail, and we will drill, baby, drill.”

Environmentalists praised Biden’s plans, saying they would prevent future oil spills that threaten coastal communities and marine wildlife.

“No one wants an oil spill off their coast, and our hope is that this can be a bipartisan historic moment where areas are set aside for future generations,” Joseph Gordon, climate and energy campaign director for the conservation group Oceana, said in a phone interview.

Biden plans to invoke the 1953 Outer Continental Shelf Lands Act, which gives the president broad powers to withdraw federal waters from future leasing. A federal judge ruled in 2019 that such withdrawals cannot be undone without an act of Congress.

The question is whether the new Republican Congress can undo this order.  If that takes overriding a Senate filibuster, Biden’s ruling may stand.

*Although Jimmy Carter was a “man of faith”, which I don’t consider a compliment, he was also a great human being and a superb ex-President, despite his coolness towards Israel. At the AP, Paul Newberry wrote an engaging piece about what it was like to go to Carter’s Sunday school classes, which he taught for years. I would have gone!

Before the former president entered the sanctuary, with a bomb-sniffing dog outside and Secret Service agents scattered around, a strict set of rules would be laid out by Ms. Jan — Jan Williams, a longtime church member and friend of the Carters. She would have made quite a drill sergeant.

It felt like a good-cop, bad-cop routine. Ms. Jan barking out rules you knew had come straight from Mr. Jimmy, who studied nuclear physics and approached all things with an engineer’s orderly mind.

Most important for those wanting a photo with the Carters — and nearly everyone did — you had to stay for the main 11 a.m. church service. Picture-taking began around noon.

If you left the church grounds before that, there was no coming back. If you stayed, you followed rules. No autographs. No handshakes. No attempts at conversation beyond a brief “good morning” or “thank you.”

Carter, consistently in sports jacket, slacks and bolo tie, would start his lesson by moving around the sanctuary, asking with a straight face if there were any visitors — that always got a laugh — and where they were from. In my many trips to Maranatha, I’m sure I heard all 50 states, not to mention an array of far-flung countries.

If anyone answered Washington, D.C., the answer was predictable. “I used to live there,” the one-term president would say, breaking into that toothy grin.

Carter’s Bible lessons focused on central themes: God gives life, loves unconditionally and provides the freedom to live a completely successful life. But the lesson usually began with an anecdote about what he’d been up to or his perspective on world affairs.

Carter could talk about building homes with Habitat for Humanity or bemoan U.S. conflicts since World War II. He could talk about his work with The Elders, a group of former world leaders, or a trip out West to go trout fishing with Ted Turner. He could talk about The Carter Center’s successes in eliminating the guinea worm, or his long friendships with Willie Nelson and Bob Dylan.

“Willie Nelson is an old friend. He used to come visit me in the White House,” Carter related once, touching ever so gently on Nelson’s affection for weed.

“I don’t know what Willie and my children did after I went to bed. I’ve heard rumors,” the former president said, with a sly grin and a wink that suggested he believed every word.

There a fair bit more, and it’s worth reading. Carter’s official funeral begins this week as his cortege heads towards Atlanta where he’ll lie in state before heading to D.C., where he’ll also lie in state in the Capitol. His body will then be returned to Plains, Georgia, where he’ll be buried next to his beloved Rosalynn.

Meanwhile in Dobrzyn, Hili is angling for noms.

The launch of a rocket into orbit should never become routine. There was a time, probably around the 50’s and 60’s that a rocket launch hit the headlines. Now its just another launch. Last year (2024) saw a record breaking 263 launches. The US launched 158, China launched 68 and other countries/regions like Europe, Russian and Japan. Last year just 224 launches were completed and two years ago in 2022, 168 launches were completed. Surprisingly perhaps, prior to 2020 the record was set at 141 back in 1967, the future of rocket flight still seems quite alive! 

Surprisingly perhaps, rocket flight in its purest form dates back centuries with its origins in ancient China. The 9th century Chinese were recorded to have fired gunpowder propelled bamboo tubes at their enemies in the first examples of rocket flight. Modern rocketry only began to take shape in the 20th century thanks to the work from engineers and scientists like Konstantin Tsiolkovsky and Robert Goddard. 

Tsiolkovsky’s theoretical work laid the foundations for rocketry, while Goddard successfully launched the first liquid-fuelled rocket in 1926 in the United States. During World War II, rocket technology advanced rapidly driven sadly for the search for weaponry not exploration. The development of the V-2 rocket by Germany marked the first long-range ballistic missile while the Cold War rivalry between the United States and the Soviet Union further accelerated rocket development. Eventually this lead to the launch of Sputnik 1 in 1957 and the Apollo 11 Moon landing in 1969 and in the years that followed rocket launches for missions to explore distant planets and the establishment of space stations.

Perhaps one of the most spectacular developments over recent years and 2024 saw this demonstrated beautifully, spacecraft landing back successfully under rocket control. SpaceX have been driving this technology forward at pace firstly with the landing of their Falcon rockets on drone ships but last year saw a real milestone.

October saw the 5th test flight of the SpaceX Starship launch vehicle. Its the tallest launch vehicle to have flown, beating the Apollo Saturn V rocket by 11 metres. After its launch on 13 October and the upper stage being delivered into a suborbital trajectory (reached space but didn’t complete an orbit before returning) the booster returned! It didn’t just disintegrate or flat down attached to parachutes, it used the powerful Raptor engines to return to the launch pad. After descent, it slowed, almost hovering in mid air, before manoeuvring sideways to line up with launch pad before touching back down. As it returned to the arms of the launch tower, the arms grabbed the rocket and the engines shut down!

It is no doubt that 2024 saw some amazing developments in rocket flight including but not limited to the SpaceX booster landings. What of 2025? What can we look forward to in the year ahead? Well I’m not sure we are going to see any pure rocket launch landmarks this year but there are some exciting missions ahead; NASA launching SPHEREx (new space observatory to map the sky in optical and near-infrared,) SpaceX launching to missions to surface of Moon (Texas built Blue Ghost and a Japanese lander,) a new commercial space station called Haven-1 and if all goes to plan we may finally see the return to Earth of Suni Williams and Butch Wilmore who have been stuck on the ISS since June after their planned 1 week mission!

The post There Were Over 260 Orbital Launches in 2024. A New Record appeared first on Universe Today.

Mars is well-known for its dust storms, which occur every Martian year during summer in the southern hemisphere. Every three Martian years (five and a half Earth years), these storms grow so large that they are visible from Earth and will engulf the entire planet for months. These storms pose a significant threat to robotic missions, generating electrostatic charges that can interfere with their electronics or cause dust to build up on their solar panels, preventing them from drawing enough power to remain operational.

While scientists have studied these storms for decades, the precise mechanisms that trigger them have remained the subject of debate. In a new study, a team of planetary scientists at the University of Colorado Boulder (CU Boulder) has provided new insight into the factors involved. According to their findings, relatively warm and sunny days may kick off the largest storms every few years. These could be the first step toward forecasting extreme weather on Mars, which is vital for future crewed missions to Mars.

The study was led by Heshani Pieris, a graduate student at the Laboratory for Atmospheric and Space Physics (LASP) at CU Boulder. She was joined by Paul Hayne, a researcher at LASP and an associate professor at the Department of Astrophysical and Planetary Sciences at CU Boulder. Their findings were presented at the 2024 meeting of the American Geophysical Union, which took place from December 9th to 13th in Washington, D.C.

Mars experiences dust storms regularly, which often begin as smaller storms that form around the polar regions, usually during the second half of the Martian year. These storms can grow rapidly as they move towards the equator until they cover millions of square kilometers. While these dust storms are not very powerful due to Mars’ thin atmosphere (roughly 0.5% as dense as Earth’s), they can still pose a significant hazard. In fact, global dust storms were responsible for the loss of the Opportunity rover in 2018 and the InSight lander last year.

“Dust storms have a significant effect on rovers and landers on Mars, not to mention what will happen during future crewed missions to Mars. This dust is very light and sticks to everything,” said Pieris in a recent NASA press release. “Even though the wind pressure may not be enough to knock over equipment, these dust grains can build up a lot of speed and pelt astronauts and their equipment,” added Hayne. “We need to understand what causes some of the smaller or regional storms to grow into global-scale storms. We don’t even fully understand the basic physics of how dust storms start at the surface.”

For their study, Pieris and Hayne focused on “A” and “C” storms, two weather patterns that tend to occur every year on Mars. This consisted of analyzing data gathered by the Mars Climate Sounder instrument aboard NASA’s Mars Reconnaissance Orbiter (MRO) over the course of 15 years (eight Mars years). Specifically, they searched for periods of unusual warmth, when more sunlight filtered through Mars’ thin atmosphere to heat the planet’s surface. They discovered that roughly 68% of major storms on the planet were preceded by a sharp rise in temperatures at the surface, which led to dust being kicked up.

While these results don’t definitively prove that warmer conditions cause dust storms, they indicate that the same phenomena that trigger storms on Earth may be at work on Mars. During hot summers in dry regions, warm air near the surface can rise through the atmosphere, leading to large gray clouds that signal rain. Said Pieris:

“When you heat up the surface, the layer of atmosphere right above it becomes buoyant, and it can rise, taking dust with it. This study is not the end all be all of predicting storms on Mars. But we hope it’s a step in the right direction.”

Pieris and Hayne are now gathering more recent observations of Mars to continue investigating these explosive weather patterns. Eventually, they hope that scientists will be able to predict weather patterns on Mars based on live data from the planet.

Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!

Chemistry researchers have taken a key step toward next-generation optical computing and memory with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back again.

Bioengineers have developed a new construction kit for building custom sense-and-respond circuits in human cells. The research could revolutionize therapies for complex conditions like autoimmune disease and cancer.

CubeSats can be used in many different scenarios, and one of their most important uses is providing an easy path to understanding how to design, plan, and launch a mission. That was the idea behind AlbaSat, a 2U CubeSat currently under development by a team at the University of Padova with an impressive four different functional sensors packed into its tiny frame.

AlbaSat was initially developed as a student project at the University of Padova as part of ESA’s Fly Your Satellite (FYS) program, which, through its two iterations, has helped students get their CubeSat ideas off the ground – literally. AlbaSat was one of the more ambitious projects in the program, with four different key scientific objectives.

First was a study of the prevalence of space debris, which is becoming a growing problem, as the team noted in their paper describing the mission’s feasibility when they discussed Kessler Syndrome. Tracking small debris floating in orbit is a challenge from the ground, but a satellite in orbit itself could do better. To do so, the team developed the Impact Sensor, which would detect debris hitting AlbaSat itself. It consists of a resistive sensing element placed on top of some PTFE, which was prototyped in a project called DRAGONS by researchers at the Fraunhofer Institute for High-Speed Dynamics.

AlbaSat will also carry a tri-axial MEMS accelerometer to complement that instrument to detect any micro-vibrations the satellite experiences in its orbit. It is important to understand what impact, if any, those vibrations might have on either satellite performance or orbital decay.

Another complementary payload is the laser rangefinder. This is intended to keep precise track of the satellite’s orbit by reflecting a laser from a ground station off of a series of “Corner Cube Retroreflectors” that can reflect the laser to the transmitting station. Understanding the orbital path is key to ensuring the other payloads onboard the tiny CubeSat work properly.

The final functional payload is a test rig for optical receivers that might someday be useful in proving novel communications technology. Known as the “QPL,” this subsystem consists of an active reflectometer that can receive signals intended for use in quantum communications systems. 

A NanoMind A3200 central computer, a NanoCom AX100 communication system, the necessary electrical subsystems, solar panels, and the functional payloads for energy collection. The mission is designed to last as long as possible, but its orbit will decay in less than 12 years, per ESA debris mitigation guidelines.

Fraser talks about the danger posed by Kessler Syndrome, one of the primary study areas of the AlbaSat mission.

Students from the University of Padova have been diligently working on the system. In February, they passed environmental testing of the impact sensor, which garnered them a press release from ESA itself. More recently, Space Voyaging published a detailed profile that tracked the team as they interfaced with ESA experts, helping them get their satellite into space.

When they do, it will be the University of Padova’s first foray into the CubeSat space. Hopefully, it will be a worthy addition to the stable of student-designed CubeSats that contribute valuable scientific data. It hopes to launch sometime this year, and it will carry many students’ hopes.

Fast radio bursts (FRBs) are notoriously difficult to study. They are flashes of radio light that can outshine a galaxy but often last for only a fraction of a second. For years, all we could do was observe them by random chance and wonder about their origins. Now, thanks to wide-field radio telescopes such as CHIME, we have some general understanding as to their cause. They seem to originate from highly magnetic neutron stars known as magnetars, but the details are still a matter of some debate. Now a team has used a method known as scintillation to reveal more clues about this mysterious phenomenon.

Most FRBs occur in distant galaxies, meaning that their light must travel through the intergalactic medium and through the interstellar medium of the Milky Way to reach us. As a result, the light can be affected by gas and dust, causing it to distort a bit in frequency and polarization. Since different media affect different wavelengths of radio light, this can help us understand the origins of an FRB.

In this study, the team focused on an FRB named 20221022A, which originated in a galaxy 200 million light-years away. As the light traveled to us, interaction with the intergalactic medium caused the burst to flicker in brightness, known as scintillation. It’s similar to the way stars twinkle because their light passes through turbulent layers of Earth’s upper atmosphere.

One of the classic ways to distinguish a star from a planet in the night sky is that stars twinkle, but planets don’t. The light of both passes through the atmosphere, but since planets appear as a small disk of light, we don’t see them flicker. Stars appear as points of light, so we can see the flicker. The apparent size of a light source is the key factor.

In the same way, by looking at the scintillation of the FRB, the team was able to determine the size and location of the FRB light source. In this case, they found that FRB 20221022A had to have happened within 10,000 kilometers of a highly magnetic pulsar. This means the FRB must have originated within the magnetosphere of the pulsar, which confirms magnetars as the source of this particular FRB.

This study not only confirms magnetars as the source of FRBs; it proves that it is specifically an effect of their intense magnetic fields. Further observations such as this should allow us to understand how these magnetic fields can generate such intense radio light so quickly.

Countries have pledged to phase out HFC-23, a powerful greenhouse gas, but atmospheric data shows that emissions are five times higher than governments are reporting

I’ve posted several times on the claim that humans have an innate longing for God that must be filled by either religion or some simulacrum of religion. This is the famous “God-shaped hole” in our psyche claimed by believers and those whom Dan Dennett called “believers in belief.” This trope appears regularly, and the last time I discussed the “God-shaped hole” was on Christmas Eve when a Free Press article described an atheist mother lamenting the absence of religious traditions to which she could expose her children on Christmas.

With the recent kerFFRFle in which some people (including me) argue that wokeness and gender activism have taken the form of a quasi-religion—a claim that’s the subject of a whole book by John McWhorter—some people have taken to blaming atheists for creating this hole and for the need for something to replace traditional faiths. By taking away people’s religion, they say, we have made society worse as erstwhile believers start glomming onto all kinds of nonsense. (Apparently religion is a good form of nonsense.)

Well, yes, some people do need god, but that need has declined steadily in the West, and in many places the hole doesn’t seem to be filled with quasi-religions.  Northern Europe and Scandinavia, for instance, have long become largely atheistic. Exactly 0% of Icelanders under 25 believe that God created the world, and 40% of them identify as atheists.  But is Scandinavia filled with especially woke people, clinging to crystals and other forms of woo, and being the most gender-activist people in the world? Not that I know of.  So my thesis is that while some people will always need God, many do not, and their numbers will decrease over time as the world population becomes better and better off. (Religiosity is negatively correlated with well being and other indices of happiness.)

And really, isn’t it condescending to say that we atheists should not publicly criticize belief in gods because it might create even worse forms of religion?  Are we supposed to shut up about the harms and false claims of traditional faiths? That’s simply a “little people” argument, one founded on “belief in belief.”

In today’s Spectator, Richard Dawkins takes up the god-shaped hole argument, though he concentrates largely on recent accusations that he himself helped dig that hole. Click the headline below to read, or find the article archived here.

Here are two people accusing Richard of wielding the Atheistic Shovel:

An irritating strain of the Great Christian Revival is the myth of the God-shaped hole. “When men choose not to believe in God, they then believe in anything.” The famous aphorism, which GK Chesterton never uttered, is enjoying one of its periodic dustings-off, following the vogue for women with penises and men who give birth. Whenever I sound off against this modish absurdity, I’m met with a barrage of accusations. “Frankly Richard, you did this. You defended woke BS for years” (of course I didn’t: quite the opposite but, for this believer in the God-shaped hole, discouraging theism is indistinguishable from encouraging woke BS). “But don’t you see, you helped to bring this about.” “What do you expect, if people give up Christianity?” Then there’s this, from a Daily Telegraph opinion column:

“New Atheists allowed the trans cult to begin. . . By discrediting religion, Dawkins and his acolytes created a void that a new, dangerous ideology filled.”

And here’s Debbie Hayton on The Spectator’s website, writing (mostly reasonably) about a recent episode in which Jerry Coyne, Steven Pinker and I resigned from the Honorary Board of an atheist organisation that’s been taken over by the trans cult:

“An atheistic organisation worth its salt would oppose these movements in the same way that it opposes established religion, so Coyne, Pinker and Dawkins are right to walk away. But maybe the key lesson from this sorry debacle is that it is not so easy to expunge the need for religion from human beings than atheists might like to think. If there is a God-shaped hole in us then without established religion, something else is likely to take its place.”

There are other arguments, but  Dawkinss concludes that the rejection of what he calls “trans nonsense” (I’d call it “gender-activist extremism”) should be based not on the fact that it replaces the supposed benefits of religion, but on science itself:

The scientific reasons are more cogent by far. They are based on evidence rather than scripture, authority, tradition, revelation or faith. I’ve spelled them out elsewhere, and will do so again but not here. I’ll just support the claim that the trans-sexual bandwagon is a form of quasi-religious cult, based on faith, not evidence. It denies scientific reality. Like all religions it is philosophically dualistic: where conventional religions posit a “soul” separate from the body, the trans preacher posits some kind of hovering inner self, capable of being “born in the wrong body”. The cult mercilessly persecutes heretics. It abuses vulnerable children too young to know their own mind, encouraging them to doubt the reality of their own bodies, in extreme cases inflicting on those bodies irreversible hormonal, and even surgical damage.

. . . How patronising, how insulting to imply that, if deprived of a religion, humanity must ignominiously turn to something equally irrational. If I am to profess a faith here, it is a faith in human intelligence strong enough to doubt the existence of a God-shaped hole.

This dispels the argument that people must hold irrational beliefs—”quasi religions”—to replace real religions.  I would extend the argument a bit further, though.  While admitting that it’s hard for some folks to let go of gods, I’ll also argue that quasi-religion nonsense can be laid at the door not of atheism, but of the kind of faith that leads people to embrace important beliefs without good evidence.
