Asteroid mining companies are finally getting off the ground, and that is raising some concerns about the impact those activities will have on the space environment. A new paper published in Acta Astronautica from Anna Marie Brenna of the University of Waikato in New Zealand discusses a framework that she thinks might work to solve the legal challenges facing those who want to protect the space environment and those who want to exploit it.

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, revealing surprising twists in how it flows through our galaxy.

We have a timely contribution, and a bit of duck-related drama in New Jersey, from Jan Malik, whose captions and story are indented below. (The duck was, in the end, unharmed.) You can enlarge the photos by clicking on them.

Here is a short series of pictures from Barnegat Light that I took about twelve years ago. I was sitting on the rock jetty one February day, scanning for any passing seabirds, when something in the corner of my eye caught my attention: a commotion farther out in the inlet channel. A duck was being attacked by a large gull.

Trigger warning and spoiler alert: the gull went hungry— the duck escaped that morning.

The prey: Long‑tailed Duck (Clangula hyemalis)

This isn’t the actual bird that was attacked; I think I photographed this one later that day. But like the victim, it was probably an immature male. Long‑tailed Ducks form large flocks outside the breeding season, wintering offshore from the Arctic Ocean, Norway, Greenland, and Canada, and reaching New Jersey when the weather turns especially cold. Unfortunately, their IUCN status is Vulnerable, and based on my very unscientific observations over twenty years of winter trips to the Jersey shore, their numbers seem to be declining.

The drama begins: the duck is caught by a Great Black‑backed Gull (Larus marinus).

These gulls—the largest species in the family Laridae—are powerful scavengers and opportunistic predators. I don’t see them often at Barnegat Light or other exposed coastal areas; they seem to prefer city dumps and places with more edible refuse than the clean, wind‑swept inlet.

Each bird pulls in a different direction.  The duck tries to dive, while the gull attempts to lift its prey and carry it to land, where it can kill it properly by violent shaking.

Given the size difference, the duck can’t fight back All it can do is try to slip free:

A second gull arrives The possibility of a meal attracts another gull, which immediately tries to steal the catch. This actually helps the duck—when raptors (if we can stretch the term to include gulls) quarrel over prey, they often drop it:

The gull’s grip is weak.  Here it’s clear that not all is lost for the duck. The gull’s smooth, non‑serrated bill has only a tenuous hold on the duck’s feathers, and it’s far from securing a proper grip:

The gull’s feet offer no help. Like other gulls, Great Black‑backed Gulls have webbed feet built for paddling, not grasping. Their only real weapon is the bill, and in this case it wasn’t placed well enough to subdue the duck:

The hunt ends unsuccessfully.  The duck breaks free and immediately dives. Long‑tailed Ducks can dive 100–200 feet (30–60 m) and swim underwater using both their feet and wings, much like penguins:

Another Long‑tailed Duck in flight.  I include this photo to show why the species is called “long‑tailed,” although this individual doesn’t have the longest tail I’ve seen. These ducks were once called “Oldsquaw” in the United States and “Old Wife” in parts of England, but in the early 2000s the name was changed because it was considered offensive. I agree with the change, though I sometimes wonder whether it marked the beginning of the slippery slope that later led to Audubon being “canceled” and many other biological names being flagged as candidates for revision.

JAC:  All’s well that ends well.

Scientists have proposed a surprising connection between solar flares and earthquakes. When solar activity disturbs the ionosphere, it may generate electric fields that penetrate fragile fracture zones in Earth’s crust. If a fault is already critically stressed, this extra electrostatic pressure could help trigger a quake. The idea doesn’t claim direct causation, but it offers a fresh way to think about how space weather and seismic events might interact.

If you’ve been following exoplanet research over the last couple of years, you’ve definitely heard of K2-18b. Located 124 light years away in the constellation Leo, it’s attracted a lot of attention as it sits squarely in its red dwarf host star’s habitable zone, and measurements of the James Webb Space Telescope show its atmosphere is rich in carbon dioxide and methane. It’s one of the prime candidates for a “Hycean” world - one where a thick hydrogen-rich atmosphere covers a global liquid water ocean. It is such an intriguing target for Search for Extraterrestrial Intelligence (SETI) researchers that they turned two of the most powerful radio telescopes in the world to watch K2-18b’s system. A recent paper, available in pre-print on arXiv, shows that there is likely no artificial narrow-band radio signals that are equivalent to our technology level coming from the planet, despite millions of potential hits.

Duplicating the information held in quantum computers was thought to be impossible thanks to the no-cloning theorem, but researchers have now found a workaround

There have been plenty of attempts to resolve the “Hubble Tension” in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on different values depending on how you measure it. A new NASA Institute for Advanced Concepts (NIAC) Phase I report on the Cosmic Positioning System (CPS) details another potential solution to it - this one involving a network of five far-flung satellites spread throughout the solar system.

Titan, the largest moon of Saturn, may have been even more instrumental to the system’s evolution than we thought, forming its rings, shaping its moons and even affecting the planet itself

CU Boulder researchers have designed microscopic “racetracks” that trap and amplify light with exceptional efficiency. By using smooth curves inspired by highway engineering, they reduced energy loss and kept light circulating longer inside the device. Fabricated with sub-nanometer precision, the resonators rank among the top performers made from chalcogenide glass. The technology could lead to compact sensors, microlasers, and advanced quantum systems.

A sweeping nationwide study has found that U.S. counties located closer to operating nuclear power plants have higher cancer death rates than those farther away. Researchers analyzed data from every nuclear facility and all U.S. counties between 2000 and 2018, adjusting for income, education, smoking, obesity, environmental conditions, and access to health care. Even after accounting for those factors, cancer mortality was higher in communities nearer to nuclear plants, particularly among older adults.

Our solar system is home to a wide diversity of planetary bodies, boasting eight planets, five officially recognized dwarf planets, and almost 1,000 confirmed moons. The eight planets consist of the four rocky (terrestrial) planets of the inner solar system and the four gas giant planets of the outer solar system. The largest planet in our solar system is Jupiter, measuring a radius and mass of 11 and 318 times of Earth, respectively. However, the discovery of exoplanets quickly altered our understanding of planetary sizes, as several have been discovered to have masses and radii several times that of Jupiter. So, how big can planet get, and are there limits to their sizes?

One way of studying and understanding distant, hard-to-reach locations elsewhere in the Solar System is to find analogues of them here on Earth. For example, deserts and lava fields are often used to understand aspects of the Martian surface. In new research, scientists collected samples from natural geysers in the Utah desert to try to understand the Solar System's icy ocean moons.

I’m not sure who Frederick Alexander is, but he’s written an intriguing article at The Gadfly (click below to read for free)

Alexander lists five types of “progressives”, and although their characteristics are distinct, he avers that their natures interlock to reinforce “progressivism”, which he sees, as most of us do, as performative wokeness that serves as a form of virtue signaling.  And yes, two of the subspecies really believe the ideology. I’ll give the five types (indented), but it’s fun to try to think of examples of each one.  I have omitted some of the descriptions in the interest of space.

The True Believers are the rarest and most dangerous type. Usually found in university admin or HR, they genuinely think that questioning any aspect of progressive orthodoxy constitutes harm. The moment they make eye contact with reality, their pupils dilate, and they assume a glazed, faraway look like someone’s talking to them through an earpiece only they can hear.

It’s the Tavistock clinician who dismissed parents’ concerns about rushing children into transition as “transphobia”. It’s the university administrator who considers “women” a radioactive word and the niqab an expression of female empowerment. It’s the civil servant who enforces unisex toilets because questions of “dignity” matter more than safeguarding.

The Careerists know it’s all nonsense but have mortgages. They privately roll their eyes at the latest pronoun updates but champion them in the board meeting with the enthusiasm of a North Korean newsreader.

Examples include the BBC editor who knows “pregnant people” is absurd but issues the apology on behalf of the female presenter who corrected the autocue to “women”. It’s the museum curator who rewrites exhibition labels to acknowledge “problematic legacies” to satisfy the demands of the True Believer, who controls the money.

The Cowards are everywhere. They know exactly what’s happening, hate it, but will never say so out loud. They’re the sort who’ll text you “100% agree!” after you’ve been fired but somehow missed every opportunity to back you up before the True Believer called you in about your unconscious bias.

When Kathleen Stock was hounded out of Sussex University, the Coward thought it was outrageous right up to the moment they realised they could be next. Then they recalibrated the events in their mind and took a different view.

. . .The Opportunists don’t care either way but have spotted the angles. Young, ambitious, and morally vacant, they add a dozen causes to their personal website and say things like “centring marginalised voices” without meaning a word of it.

The Opportunist will launch a DEI consultancy today and charge an HR True Believer ten grand tomorrow to tell a roomful of Careerists they’re racists. Or they’ll be the author who went from wellness influencer to decolonisation expert in 18 months and set up a podcast in between. It’s the academic who discovered that adding “queer theory” to their research proposal tripled their funding chances.

. . .The Fanatics think they’re True Believers except they dial it up to eleven. Pronouns and watermelon emojis in the bio, sure. But they also believe in decolonising logic and think the world is going to end tomorrow if we don’t do what they tell us. Every cause connects to every other cause, and all causes connect back to the same enemy.

It’s the student activist who screams at a Jewish classmate for three hours about Zionism, then files a complaint claiming she felt unsafe. It’s the protester who glues himself to a motorway, causes an ambulance delay, then calls the criticism “ableist”. The Fanatic cannot maintain eye contact except when talking about Palestine, at which point his eyes fix unblinkingly on yours, daring you to push back on his claims of genocide.

I could name a specimen of each of these, but will refrain on the grounds that you wouldn’t know most of them. Fanatics, though, include Robin DiAngelo, and True Believers the many biologists who assert that sex is a spectrum. (Some of the latter could be “careerists” as well, knowing that they can sell books and write articles, advancing themselves, by supporting nonsense.

Then, in an analysis that I like a lot, Alexander explains why these types are self-reinforcing, advancing “progressivism” as a whole (I hate calling it that; how about “wokeness”?):

Identifying these types isn’t an exact science, and they overlap to various degrees. The crucial thing to understand is that they need each other.

True Believers provide the moral authority, write the policies, and enforce the rules with genuine conviction. They absorb the ideology and give it form. Without them, it would all feel like a game of pretend (which it is).

Careerists provide the manpower. They actually implement the nonsense without stopping to think much about what any of it means.

Cowards provide the silence and the illusion of consensus, allowing the system to expand unopposed.

The Opportunists provide the raw energy, finding new ways to monetise moral exhibitionism because they see progressive orthodoxy as a business opportunity. Celebrity activists – indeed the whole entertainment industry – fall into this category.

Fanatics provide the threat. They’re the enforcers who make the Careerists think twice about cracking a joke since every joke has a victim. The Coward looks at them and thinks at least I’m not that person in an effort to assuage the sense of disgust at their own lack of integrity.

The system rewards all of them. True Believers get authority. Careerists get promotions. Cowards keep their heads down and Opportunists get book deals. Fanatics get the attention they crave, which is why we’re forever seeing clips of them in our social feeds waving Palestinian flags or throwing soup at Van Gogh.

What they all get – every single one – is protection from consequences.

Why? Because progressive orthodoxy is sustained by particular incentives. It’s got nothing to do with the strength of the ideas, most of which are obviously terrible when examined under daylight. It’s about the incentives that come with compliance and the costs that come with dissent.

In the end, Alexander still thinks the ideology is doomed to disappear:

The good news is that every protection racket collapses eventually – and progressivism will be no exception. The lawsuits will become too expensive, the backlash too loud to ignore. Those politicians who told us that men can be women will explain with a frown that these were “challenging times” rather than a gruesome display of moral cowardice. Pronouns in bios will become so mortifyingly embarrassing that those who had them will pretend, even to themselves, that they never dreamt of anything so silly.

Well, I’m not so sure he’s right here, but one can hope. The Democratic Party has been influenced too long by “progressivism,” and that shows no signs of disappearing. Indeed, it’s growing, to the point where Nate Silver lists Gavin Newsom and Alexandria Ocasio-Cortez as the two top Democratic candidates for President. (Remember, though, that it’s early days.) AOC is clearly a progressive, a combination of Fanatic and Careerist, while Gavin Newsom used to be progressive but, starting to realize he can’t win the Presidency that way, has been moving towards the center. He’s clearly a combination of Careerist and Opportunist.

In the meantime, have fun by listing below individuals falling into the five classes given above.
