And as we tampered with the elements in our hubris, an ancient city emerged from the depths…

There are a number of ways in which climate change, and the effect it’s having on our planet, is absolutely fascinating. We get to see species and ecosystems evolve in response to things that have never happened in human history, let alone the history of the scientific method. If it wasn’t for all the death and misery, this would be a golden opportunity for research.

It still is an opportunity for research, despite the tragic circumstances, and we are learning things about our world, and also about ourselves. A drought in Iraq has dried up a reservoir to the point where a Bronze Age city has been uncovered.

Iraq is one of the countries in the world most affected by climate change. The south of the country in particular has been suffering from extreme drought for months. To prevent crops from drying out, large amounts of water have been drawn down from the Mosul reservoir – Iraq’s most important water storage – since December. This led to the reappearance of a Bronze Age city that had been submerged decades ago without any prior archaeological investigations. It is located at Kemune in the Kurdistan Region of Iraq.

This unforeseen event put archaeologists under sudden pressure to excavate and document at least parts of this large, important city as quickly as possible before it was resubmerged. The Kurdish archaeologist Dr. Hasan Ahmed Qasim, chairman of the Kurdistan Archaeology Organization, and the German archaeologists Jun.-Prof. Dr. Ivana Puljiz, University of Freiburg, and Prof. Dr. Peter Pfälzner, University of Tübingen, spontaneously decided to undertake joint rescue excavations at Kemune. These took place in January and February 2022 in collaboration with the Directorate of Antiquities and Heritage in Duhok (Kurdistan Region of Iraq).

[…]

Within a short time, the researchers succeeded in largely mapping the city. In addition to a palace, which had already been documented during a short campaign in 2018, several other large buildings were uncovered – a massive fortification with wall and towers, a monumental, multi-storey storage building and an industrial complex. The extensive urban complex dates to the time of the Empire of Mittani (approx. 1550-1350 BC), which controlled large parts of northern Mesopotamia and Syria.

“The huge magazine building is of particular importance because enormous quantities of goods must have been stored in it, probably brought from all over the region,” says Puljiz. Qasim concludes, “The excavation results show that the site was an important center in the Mittani Empire.”

The research team was stunned by the well-preserved state of the walls – sometimes to a height of several meters – despite the fact that the walls are made of sun-dried mud bricks and were under water for more than 40 years. This good preservation is due to the fact that the city was destroyed in an earthquake around 1350 BC, during which the collapsing upper parts of the walls buried the buildings.

I want to pause here to say that the United States in particular owes the people of Iraq for decades of meddling and war. No politician of that country can claim to care about peace or justice until reparations have been made, and that’s just one of many countries on that list.

I don’t know the exact damage this drought is doing, but given the condition the country was already in, this just feels like the universe is piling on. That said, I’m glad they’re able to take the chance to study this piece of history. Some of what they’re finding is pretty neat!

Of particular interest is the discovery of five ceramic vessels that contained an archive of over 100 cuneiform tablets. They date to the Middle Assyrian period, shortly after the earthquake disaster struck the city. Some clay tablets, which may be letters, are even still in their clay envelopes. The researchers hope this discovery will provide important information about the end of the Mittani-period city and the beginning of Assyrian rule in the region. “It is close to a miracle that cuneiform tablets made of unfired clay survived so many decades under water,” Pfälzner says.

I’m generally frustrated by the way society is just carrying on as if we’re not facing an existential threat, but one big exception to that is the various fields of academia. Despite popular mythology, most of this stuff is woefully underfunded (understanding the past doesn’t seem to be profitable), and I’m honestly glad that these researchers are continuing to push ahead with their work as circumstances allow.

Nature says Happy Pride Month!

I’ll have something else up today, but I wanted to share this incredible rainbow waterfall with y’all. I know the tweet says “potentially sensitive content”, but that’s bullshit, and we can talk about why that might be some other time, perhaps

Edit: Turns out I was wrong. I got sidetracked by other projects, so this is all you get from me until tomorrow.

For now, enjoy the pretty video:

 

I’m gonna make a pollinator garden!

I’m often slow to do new things, but when I’m already feeling overwhelmed – as I was with the international move last year – I become downright glacial. I’ve been meaning to do some gardening since we moved here, but I’ve had trouble getting around to actually DOING it. Now, I’ve decided that I’m going to get a set of window boxes, and plant a pollinator garden on the roof of our storage shed. I’ll share pictures of the process as it goes forward, but for now I wanted to talk about why I’m doing this.

On the surface, it’s obvious, right? Insect populations around the world seem to be in a state of collapse, and that includes the ones that pollinate not just our food crops, but also the many wild plants that inhabit the ecosystems around us. There’s very little I can do about global use of pesticides, but I can at least try to make the landscape a bit more hospitable. There are a lot of flowering plants in my neighborhood, which is very nice, but I honestly don’t know if they meet the needs of everything that might be living around here. At the very least, adding another patch of flowers should help.

That’s not the only reason I’m doing this, though. I’m mainly doing it for my personal mental wellbeing. With everything going on in the world, it’s hard not to be consumed by apathy and despair. From what I can tell, the best counter to that is to find some way to take action. It’s not because the actions of any individual are going to change things, or even the idea that “if we all do it the world will be saved”. It’s more that our brains have a much easier time contemplating problems if we feel like something is being done about them. The more certain of that we are, the easier it is to think about something terrifying, like climate change. If the “something” that’s being done is being done by us, then there’s zero question about whether something’s being done, right? Because we’re the ones doing it.

So I’m gonna make a pollinator garden.

I’m also looking into things like neighborhood or river cleanup groups, because while I’d be perfectly happy with the life of a hermit, I feel I ought to practice what I preach. This may not be the most important work I could do, but I think it could help me make good connections, and get a better idea of what sort of thing I might prefer doing if this approach doesn’t work out

For the garden, I’m going to start by researching local pollinator species, and looking for gaps I might be able to fill. I’m also going to get some window boxes to put on top of my portion of the storage shed, as that seems like it might be a nice, out-of-the-way spot. I’m not sure if it gets enough sun, but I suppose that’ll depend on what seeds I can get. I can also see it out of the window of my workroom, so it should be pretty easy to keep an eye on the plants and see how they’re dong. I’ve seen a few bumblebees around this spring and summer, but nothing like what I’d expect for the weather, or the number of flowers around. I don’t know if that means my contribution won’t make a difference, and it feels a bit too little/too late, but I might as well try. I’ll also take pictures of the project as it develops.

Video: Disinvestment is class war

It’s not just the private sector that works to funnel money to the top. The government also plays its role in ensuring that poverty is miserable and dangerous enough to make people desperate for any wage they can get, no matter how bad the working conditions. It’s not a coincidence that the bipartisan response to people refusing to go back to work was to cut unemployment assistance, and try to use poverty to force people to go back. The United States, as a rule, treats poverty as a moral failing. Even as it’s made impossible to escape, poverty itself is seen as justification for mistreatment of poor people. It also justifies poor working conditions and poverty wages, because if they “deserved more” they’d have better jobs. It’s a vicious circle designed to deflect attention away from the simple fact that poverty is a policy choice.

 

Golden flying salamanders? In your redwoods? It’s more likely than you might think!

When I was in college, a fellow student bought several “flying” geckos to look into how much they actually steered while in the air. I honestly don’t recall what the verdict was, but I think they did fall differently when blindfolded. Helping with this research project also gave me a small insight into the exotic pet trade. These geckos were all wild-caught, and they all had worms when they arrived. In the end, seven of ten died before an effective treatment was found, and one not long after that. I’m sure that the stress of capture and transportation made everything worse. At the end, I took the two surviving geckos as pets, and they lived with me for about another year before dying.

It was always fun to see them catching the moths I gave them, and to watch them seemingly teleport from one side of the terrarium to the other, and it was fascinating to watch them steer towards the best landing spot (either the slanted sheet that was used as a net below the balcony, or the person holding that sheet). The way various lizards and frogs have evolved to be able to glide and navigate in the air has always fascinated me, but I have to admit that I never expected to hear of an arboreal, gliding salamander.

Salamanders that live their entire lives in the crowns of the world’s tallest trees, California’s coast redwoods, have evolved a behavior well-adapted to the dangers of falling from high places: the ability to parachute, glide and maneuver in mid-air.

Flying squirrels, not to mention numerous species of gliding frogs, geckos, and ants and other insects, are known to use similar aerial maneuvers when jumping from tree to tree or when falling, so as to remain in the trees and avoid landing on the ground.

Similarly, the researchers suspect that this salamander’s skydiving skills are a way to steer back to a tree it’s fallen or jumped from, the better to avoid terrestrial predators.

“While they’re parachuting, they have an exquisite amount of maneuverable control,” said Christian Brown, a doctoral candidate at the University of South Florida (USF) in Tampa and first author of a paper about these behaviors. “They are able to turn. They are able to flip themselves over if they go upside down. They’re able to maintain that skydiving posture and kind of pump their tail up and down to make horizontal maneuvers. The level of control is just impressive.”

The aerial dexterity of the so-called wandering salamander (Aneides vagrans) was revealed by high-speed video footage taken in a wind tunnel at the University of California, Berkeley, where the salamanders were nudged off a perch into an upward moving column of air simulating free fall.

“What struck me when I first saw the videos is that they (the salamanders) are so smooth — there’s no discontinuity or noise in their motions, they’re just totally surfing in the air,” said Robert Dudley, UC Berkeley professor of integrative biology and an expert on animal flight. “That, to me, implies that this behavior is something deeply embedded in their motor response, that it (falling) must happen at reasonably high frequencies so as to effect selection on this behavior. And it’s not just passive parachuting, they’re not just skydiving downwards. They’re also clearly doing the lateral motion, as well, which is what we would call gliding.”

I always love it when scientists discover something new about a species they thought they knew. I also love discovering animals with cool metallic coloring – just look at this little amphibious gold nugget!

I think this story is really cool, and there’s more in the article I linked. I wanted to focus on one bit in particular. See, I’ve noticed that when it comes to discerning the evolutionary purpose for a given trait, I feel like one of the questions on any dichotomous key would have to be “does this conserve energy?”

Brown suspects that their aerial skills evolved to deal with falls, but have become part of their behavioral repertoire and perhaps their default method of descent. He and USF undergraduate Jessalyn Aretz found, for example, that walking downward was much harder for the salamander than walking on a horizontal branch or up a trunk.

“That suggests that when they’re wandering, they’re likely walking on flat surfaces, or they’re walking upward. And when they run out of habitat, as the upper canopy becomes drier and drier, and there’s nothing else for them up there, they could just drop back down to those better habitats,” he said. “Why walk back down? You’re already probably exhausted. You’ve burned all your energy, you’re a little 5 gram salamander, and you’ve just climbed the tallest tree on Earth. You’re not going to turn around and walk down — you’re going to take the gravity elevator.”

I’m of the opinion that life exists because it’s better at breaking things down than non-life. On a cosmic time scale, the entropy “lost” in the development of life is “regained” as we break down our environment to survive. That said, conserving energy is still a big concern for most organisms, so if there’s gonna be an arboreal salamander, it absolutely makes sense that controlled falling would be preferable to all that bothersome climbing.

Beyond parody…

We live in the shittiest, most obnoxious timeline.

For those who can’t see, the image in the top tweet is two images pf a bomber dropping bombs. The first, labeled “Republicans”, is just a photo of a bomber. The second, labeled “Democrats” is the same bomber, with a rainbow, a BLM sign, and a “Yes she can!” sign photoshopped onto them. The bottom tweet is from the United States Marine Corp, and it’s a digital camo helmet with six rifle shells held by a band. The bullets are painted with rainbow colors.

It reminds me of a folk song I heard a while back, pointing out the absurdity of the military’s resistance to having specifically homosexual soldiers killing poor villagers for the U.S. empire, except now instead we’re supposed to celebrate that. It is progress, in a way. The advancement of civil rights, even within a flawed society, is 100% a win, and we should be glad that it’s gotten to the point where the marines of all organizations wants to be seen as supporting Pride.

But holy shit does this feel like a grim commentary on our society.

Is it June already?

As my long-time readers are well aware, this whole “posting daily” thing is a new development for me as of 2022. I’m figuring out how to manage my ADHD, but I’ve had some difficulty balancing daily posting with other things, like writing posts that are actually good, writing fiction, housekeeping, and so on. All of this is to say that I’m still not great at delivering on themed content as much as I’d like to, so I’m going to do some of that this month.

In our rather interesting tradition of designating months for awareness of particular causes, it seems that June 2022 is the month for at least three issues that I feel I ought to address. The first (in order of my becoming aware of it) is Pride Month – an international celebration of the diversity of human gender and sexuality, and a time for furthering the cause of ensuring human rights for LGBTQIA people. In particular, I want to talk about the ways in which the United States is becoming more dangerous for trans people, because there’s a lot happening in that area, and it’s quite frankly horrifying.

The second is Canada’s National Indigenous History Month, for which I’ll be writing about the contents of one or more of these reports. Someone I follow on Twitter made a general request that settler types do so, and that’s a good enough reason for me. That said, it’s not the only reason. There’s been a lot of news in recent years demonstrating just how much of a façade Canadian “niceness” turns out to be when it comes to its indigenous population, and I think that the citizens of one or two other countries would do well to consider how these lessons might apply to their own homes.

The third is Gypsy, Roma and Traveller History Month in the United Kingdom. I have to admit I know very, little about these groups of people. For one thing, in the U.S. and other parts of the world, “Gypsy” is considered a slur, but apparently it’s been reclaimed by at least some groups in Europe, similar to how some Native Americans refer to themselves as “Indians”. Terminology is important for interacting with, and talking about people, but in my opinion it doesn’t count as learning about their culture, so much as showing the bare minimum of decency to one’s fellow humans. So I’m going to learn more, and write about it.

I think I had intended to have one of these published today, but subjects like this fall into the category of “if I’m going to do it, I should take the time to do it as well as I’m able. For me that means allowing myself to not rush the job, so instead you get this I.O.U. for posts on these topics some time this month.

In the meantime, I hope you’re all doing as well as possible as we head into the summer. News about the state of the world continues to feel relentlessly grim, so I hope you are all taking time to do things that are important to you. We’re fighting for a better world because we believe, at least in part, that those humans who come after us deserve a habitable planet and a just society, in which to lead fulfilling lives. That means that we also deserve to lead fulfilling lives, to whatever degree we can in the world as it is today. Do things that are fun. Do things that make you proud. Do things that give you meaning. It’s part of your duty to yourself.

Tegan Tuesday: Disabled activists are using South Korea’s lack of accessibility to fight for human rights

My first introduction to disability rights was at a mock trial when I was a teenager. For those unfamiliar with the structure of mock trials, schools all across the US are given the same fake trial, and students must prepare both prosecution and defense against other school districts. It’s an introduction to the law process in the US and an interesting bit of mental competition. I remember one of the years that I was competing, the plaintiff was a disabled newscaster suing a news network for discriminatory hiring practices, stating that the network was not interesting in working with a newscaster in a wheelchair.

Among the many things our team had to learn to work on this case was what counts as discrimination, and what categories of people counted as a “protected class”. In the U.S., race, color, religion, sex, national origin, disability, and age are the current protected classes. Partial protection from disability discrimination was from the Rehabilitation Act of 1973, with additional protection from the Americans with Disabilities Act of 1990 (ADA). Our fictional law case had the news station only paying attention to the original Civil Rights Act of 1964, which only protects discrimination based on race, color, religion, sex, and national origin. As an able-bodied person with no disabled people in my immediate family, I hadn’t ever considered the discrimination disabled people face. My mock trial team knew about how much effort went into getting the Civil Rights Act, and we assumed that a similar amount of effort was put in for all subsequent additions. And that’s where we left it; no actual research was done on the disability activists who made the relevant law happen.

The next time I heard much about disability activism was 2017 when activists were arrested outside Mitch McConnell’s office. The activist group ADAPT (Americans Disabled for Attendant Programs Today) had staged “die-ins” with wheelchair users abandoning their wheelchairs, making it harder to force the protesters to leave, as well as making the visual impact of removing said protesters stronger. In the many discussions and articles I read about the activists in 2017, I learned of how throughout much of the last fifty years disabled activists have been fighting. Not just for their lives, although they certainly have fought for that, but for the right to exist in public, to have jobs, to have families. One of the actions that ADAPT is known for are the protests throughout the 1980s for accessible buses. A quick summary from Wikipedia states:

Throughout the 1980s, the campaign for bus lifts expanded out from Denver to cities nationwide. ADAPTers became well known for their tactic of immobilizing buses to draw attention to the need for lifts. Wheelchair users would stop a bus in front and back, and others would get out of their chairs and crawl up the steps of an inaccessible bus to dramatize the issue. Not only city buses but interstate bus services like Greyhound were targeted. By the end of the decade, after protests and lawsuits, ADAPT finally saw bus lifts required by law as part of the Americans with Disabilities Act (ADA) in 1990.

As anyone who has ever seen or experienced the process of getting a wheelchair user onto a bus will know, the current system is still not particularly good. It varies from place to place, but it generally requires the bus to laboriously lower a ramp, let the rider wheel on, then equally-laboriously raise the ramp. The process is repeated when the rider needs to exit. It takes time, which delays the schedule, and there is often only space for one or two wheelchair users on a bus. But, technically, officially, wheelchair users are able to ride the bus with the non-wheelchair-using populace. There’s just the implied and hoped-for expectation that most wheelchair users will avoid the bus. In a world where punctuality is often so important, and time is often so short, the setup almost seems designed to focus attention – and impatience – on disabled people just trying to go about their day.

This situation isn’t limited to just the US. In both Scotland and Ireland, my experience has been that anyone requiring a mobility aid has had to make an ordeal of their entering a bus. Cue my lack of surprise to find that South Korea has a similar issue with public transit. Since mid-December, Hyehwa station in Seoul has been the center of a new fight for disability rights.

Disability rights activists, many of them in wheelchairs, have been staging subway protests to demand accommodations on public transit. And on [April 15th] the demonstrators chained themselves to each other and to a portable ladder, reenacting a 2001 protest where activists chained themselves to the subway tracks. Now they shouted, “Pass a budget for disabled citizens! No rights without a budget!” They boarded trains in groups, which requires transit workers to install and uninstall wheelchair ramps, thus causing delays. A few of the activists had recently shaved their heads in public, a monkish ritual of sacrifice.

Lee Hyoung-sook, who leads a local advocacy group, was among those with her head shaved. At Gyeongbokgung station, she tried to board the train en route to Hyehwa station. Subway workers brought out a ramp so her wheels wouldn’t get stuck in the large gap between the platform and the car. Four more wheelchair users waited their turn to board in other sections of the train. While workers moved their one ramp around to get every wheelchair activist on board, the subway doors kept closing in on them. “Fellow citizens, we sincerely apologize for the inconvenience,” Lee told her fellow passengers.

These subway protests are being led by the largest disability-rights activist group, Solidarity Against Disability Discrimination (SADD). This is far from the first time that SADD has been in the news. In 2016, the group was protesting the 6-tiered disability system that ranks the amount of support any individual can receive. The activists were visibly pulled from chairs and dragged out of an international social work conference. Current South Korean president, Yoon Seuk-yeol, is the head of the conservative People’s Power Party, and the official response from the government has been as helpful as 2016’s sanctioned violence. The head of the political party – and the president’s right-hand-man – Lee Jun-seok, has claimed that the activism is illegal, an “uncivilized backward strategy” and that the activists are “playing the minority card” to villainize the majority. My, that’s certainly a familiar conservative refrain.

According to 2020 surveys, 32% of disabled Koreans don’t have access to medical care, 85.6% of disabled Koreans have been unable to pursue higher education, and the majority of the people surveyed stated that lack of accessible transportation was the primary reason. The transit activism runs parallel to efforts to improve conditions in residential facilities, as current statistics indicate that fully half of disabled Koreans living in care homes die before age 50, and a third of them don’t even make it to 30. But care home residents are not as visible as subway stoppages, so awareness has to come from without. SADD’s demands are simple: they want the rights of disabled citizens guaranteed, same as any other citizen.

SADD currently has been demanding the government to draw up four major bills relating to the basic rights of disabled. The disabled advocacy group has been also asking the government to secure budgetary funds for disability rights in the 2023 fiscal plan, in addition to an official meeting with the new administration’s finance minister.

Laws protecting the rights, freedoms, and safety of people have always been written in blood; I hope the South Korean government sees the value in the lives of disabled people before more blood is shed.

I learned two new things about termites today!

Ok, so the first thing I didn’t know was that termites are a type of cockroach. I had no idea.

The second thing – and this honestly makes a lot of sense, given what we know about termites – is that they apparently cross oceans every now and then.

Termites are a type of cockroach that split from other cockroaches around 150 million years ago and evolved to live socially in colonies. Today, there are many different kinds of termites. Some form large colonies with millions of individuals, which tend to live in connected tunnels in the soil. Others, including most species known as drywood termites, form much smaller colonies of less than 5000 individuals, and live primarily in wood.

Researchers from the Evolutionary Genomics Unit at the Okinawa Institute of Science and Technology Graduate University (OIST), alongside a network of collaborators from across the world, have mapped out the natural history of drywood termites—the second largest family of termites—and revealed a number of oceanic voyages that accelerated the evolution of their diversity. The research, published in Molecular Biology and Evolution, shines light on where termites originated and how and when they spread across the globe. It also confirms that some species have, in recent centuries, hitched a ride with humans to reach far-flung islands.

“Drywood termites, or Kalotermitidae, are often thought of as primitive because they split from other termites quite early, around 100 million years ago, and because they appear to form smaller colonies,” said Dr. Aleš Buček, OIST Postdoctoral Researcher and lead author of the study. “But very little is actually known about this family.”

Dr. Buček went on to explain how, before this study, there was very little molecular data on the family and the little understanding of the relationships between the different species that was known was based on their appearance. Previous research had focused on one genus within the family that contains common pest species, often found within houses.

To gain overarching knowledge, the researchers collected hundreds of drywood termite samples from around the world over a timespan of three decades. From this collection, they selected about 120 species, some of which were represented by multiple samples collected in different locations. This represented over a quarter of Kalotermitidae diversity. Most of these samples were brought to OIST where the DNA was isolated and sequenced.

Every now and then, I learn about a research project, and am given a new appreciation for the amount of work some scientists will do to expand our knowledge. There’s a degree to which some of this sort of thing can be less work than it necessarily sounds like. If I said I caught and measured hundreds of turtles every year, that could be just a couple weeks of work. That would be followed by a much longer period of analysis and whatnot, but a fairly small team can collect a lot of data in a very short time, if they know what they’re doing.

Doing it over 30 years, however, requires patience and persistence that I find admirable, not to mention reliable access to resources (funding educational and research institutions should be treated as a public investment in the future).

By comparing the genetic sequences from the different species, the researchers constructed an extensive family tree of the drywood termites.

They found that drywood termites have made more oceanic voyages than any other family of termites. They’ve crossed oceans at least 40 times in the past 50 million years, travelling as far as South America to Africa, which, over a timescale of millions of years, resulted in the diversification of new drywood termite species in the newly colonized places.

Furthermore, this study has cast doubt on the common assumption that drywood termites have a primitive lifestyle. Among the oldest lineages in the family, there are termite species that do not have a primitive lifestyle. In fact, they can form large colonies across multiple pieces of wood that are connected by tunnels underground.

“This study only goes to highlight how little we know about termites, the diversity of their lifestyles, and the scale of their social lives,” stated Prof. Tom Bourguignon, Principal Investigator of OIST’s Evolutionary Genomics Unit and senior author of the study. “As more information is gathered about their behavior and ecology, we’ll be able to use this family tree to find out more about the evolution of sociality in insects and how termites have been so successful.”

“They’re very good at getting across oceans,” said Dr. Buček. “Their homes are made of wood so can act as tiny ships.”

The researchers found that most of the genera originated in southern America and dispersed from there. It takes a scale of millions of years for one species to split into several after a move. The research also confirmed that, more recently, dispersals have largely been mediated by humans.

A good portion of my life has been spent learning about the ways in which humans move other species around, and the damage that can do. It’s neat to learn about species moving themselves around, over such vast distances.
