As Biden Leaves Office, the US Empire is Desperate to Maintain Its Hegemony


This November, US president Joe Biden will leave office with the world in turmoil and US fingerprints on the bodies of untold thousands across the globe: in Gaza and Lebanon, Yemen and Syria, Cuba and Venezuela, Pakistan and Haiti, and elsewhere.

While Biden attempted to cast his foreign policy actions as defending “democracy” against “authoritarianism,” this framing is a lie. The real motive force behind the Biden administration’s bloody foreign policy is a fear of waning hegemony – of losing the benefits the US economy derives from political and economic domination of the global majority.

In that vein, the US is still trying to suffocate the model of socialist Latin American integration forwarded by Cuba and Venezuela. Washington is still arming the Israeli genocide in Palestine, the invasion of Lebanon, and other Israeli aggressions against “Axis of Resistance” forces in the region, namely Iran. On top of this, the US is still supporting or carrying out airstrikes against Yemen and Syria, still hoping to bleed Russia dry in Ukraine, still backing a Pakistani military dictatorship imposed with US backing, still engineering the re-invasion of Haiti, and still plotting an economic war (and perhaps a hot one) against China.

The Biden administration genuinely believed it could remake the world in its vision, and particularly the Middle East à la the neoconservatives of the George W. Bush administration. A Nation article by Aída Chávez laid out Biden’s disturbing plan for the Middle East and wider world, a plan that relies on Israel successfully carrying out the ethnic cleansing of Palestine:

One goal of the “Biden doctrine,” as New York Times columnist Thomas Friedman called it, is to achieve the “global legitimacy” necessary to “take on Iran in a more aggressive manner.” With Hamas out of the picture and a demilitarized Palestinian state under the influence of the Gulf regimes, the thinking goes, the US will have Arab cover in the region to be able to counter Iran – and the cheap drones they’re worried about – and then put all of its energy toward a confrontation with China.

Following Israel’s killing of Hamas leader Yahya Sinwar, US officials jumped at the chance to push “a much wider agenda – including an opening for the next stage of America’s geopolitical ambitions.” This “next stage” includes the ethnic cleansing of Palestine, the signing of a US-Saudi defence treaty, and the Gulf monarchies leading Gaza’s so-called “reconstruction” as a pro-US “emirate,” in the words of Republican Senator Lindsey Graham.

Following the killing of Sinwar, Democratic Senator Richard Blumenthal stated, “After recent conversations w/leaders of Israel, Saudi Arabia & UAE, I have real hope that Sinwar’s death creates truly historic opportunities for Israel’s security, cessation of fighting & regional peace & stability through normalization of relations. The moment must be seized.” Lindsey Graham elaborated on the “historic opportunities” of which Washington hopes to take advantage. “MBS and MBZ at the UAE will come in and rebuild Gaza,” he said in a recent interview. “[They will] create an enclave in the Palestine.”

According to Bob Woodward’s new book War, Graham reportedly told Biden, “It’s going to take a Democratic president to convince Democrats to vote to go to war for Saudi Arabia.” To which Biden responded, “Let’s do it.”

While Washington aims to violently remake the Middle East to serve its geopolitical aims – a stark contrast to China’s recent peacemaking between Saudi Arabia and Iran – other targets of imperialism continue to suffer as well.

In April 2022, the Biden administration helped engineer the removal of popular Pakistani president Imran Khan from office. The US wanted Khan ousted because he entertained positive relations with China and Russia, two powers that Washington views as a threat to its hegemony. As Assistant Secretary of State for the Bureau of South and Central Asian Affairs Donald Lu stated in a now infamous cypher to the Pakistani military, “if the no-confidence vote against the Prime Minister succeeds, all will be forgiven in Washington.”

Since the US-backed coup against Khan, the Pakistani military has taken extreme measures to prevent the ousted president’s return to power, including legal onslaughts, the arrest of thousands of supporters, crackdowns on social media activists, the imprisonment and torture of independent journalists such as Imran Riaz Khan, the decimation of Khan’s party Pakistan Tehreek-e-Insaf (PTI), and the rigging of an election earlier this year.

In other words, a de facto military junta has seized total power in Pakistan, and Washington backs them because they have reversed Khan’s non-aligned position and returned the country to the US orbit.

Meanwhile, Haiti has become a target of Washington once more. Earlier this year, the Biden administration courted Kenya’s President William Ruto to lead a US-funded invasion force into Haiti, which is wracked by violence after over a century of exploitation and underdevelopment by the US and allies, including Canada. The mission’s ostensible goal is to free Haiti from warring paramilitary gangs – however, the invasion force and its backers ignore the reality that the paramilitaries are a consequence of the brutally unequal political, economic, and social hierarchies imposed on Haiti by Global North powers. In reality, Haiti requires sovereignty and respect, not a new spiral of bloodshed and misery.

Haiti’s Caribbean neighbours, Cuba and Venezuela, have also endured immense suffering due to Biden’s imperialist policies. Cuba and Venezuela have long been targets of US imperialism – Cuba for over sixty years, Venezuela for twenty-five – and the Biden era continued this brutal interventionism. In the case of Cuba, Biden kept in place the hundreds of additional sanctions and the egregious “state sponsor of terrorism” designation imposed by Donald Trump. The Trump-Biden sanctions are harsher than any previous president’s, depriving the small Caribbean nation of billions of dollars per year. “The sanctions today,” says political scientist William LeoGrande, “have a greater impact on the Cuban people than ever before.” People are going hungry, hundreds of thousands hope to migrate, and most recently, the country’s power grid collapsed under the weight of Biden’s coercive measures.

As Drop Site news contributor Ed Augustin wrote in early October:

Government food rations [in Cuba] – a lifeline for the country’s poor – are fraying. Domestic agriculture, which has always been weak, has cratered in recent years for lack of seeds, fertilizer, and petrol, forcing the state to import 100 percent of the basic subsidized goods. But there’s not enough money to do that. Last year the government eliminated chicken from the basic food basket most adults receive. Last month, the daily ration of bread available to all Cubans was cut by a quarter. Even vital staples like rice and beans now arrive late. Food insecurity on the island is rising, according to a recent report by the Inter-American Commission on Human Rights. Vulnerable groups – older people, pregnant women, children and people with chronic illnesses – are most affected by the knock-on effects of US policy.

In all the cases described above, the Biden administration has taken extreme measures to snuff out challenges to its imperialist hegemony – measures that manifest first and foremost in the physical destruction of Palestinians and Lebanese by US-made weapons, the imposition of hunger, desperation, and migration crises on Cuba and Venezuela, the US-backed occupation of Haiti, the violent repression of Pakistanis’ desire for sovereignty and non-alignment, and more. Meanwhile, one-third of the world’s nations – and 60 percent of poor countries – face some type of US sanctions for having displeased the imperial hegemon.

The prevailing world system, a system defined by US imperialism and the imposition of the neoliberal Washington Consensus around the globe, is facing an array of challenges, from Latin America and the Caribbean to Palestine to East Asia.

How is Washington responding? Through the economic strangulation of countries like Cuba and Venezuela that present an alternative model; through a “day after” plan in the Middle East that would reduce Gaza to a neocolony of Washington and the Gulf monarchies; through coups against popular non-aligned leaders like Imran Khan; through the re-invasion of Haiti, a nation whose sovereignty has long been subverted by imperialism; through pressuring the Ukrainian government to lower the draft age so Kyiv can continue sending its young people into the meat grinder on behalf of Washington’s geopolitical aims; and through continuing to trudge the path toward war with China.

Ironically, the US empire’s violent response to its waning hegemony is expediting the emergence of an alternative world order, one marked by the de-dollarization and South-South cooperation of the BRICS group. As Biden leaves office and Trump returns to the White House, we can safely assume that the violence of imperialism will continue, perhaps intensify, and at the same time, the global majority will continue its efforts to forge new relationships outside the umbrella of US unilateralism.

The Dying — and Constantly Lying — U.S. Empire


On 25 July 1945, U.S. President Harry Truman accepted the advices from both his personal hero General Dwight Eisenhower and Winston Churchill, to 100% reverse his predecessor Franklin Delano Roosevelt’s carefully designed plan to prevent a WW3 by creating a fully armed democratic federal government of the world to create adjudicate and enforce international laws and NO national laws, and to outlaw and end the cause that had produced both World Wars, which was imperialism and the contests between them, and so he created the basis for what he named “the United Nations” to do that, but his immediate successor Truman’s version of the U.N. was/is instead a mere talking forum, with no such powers. This would allow him and Eisenhower to create the military-industrial complex to take over the entire world starting with Russia and all of its neighbors. His plan failed, but nonetheless then the Soviet Union itself failed, because of its Marxian economics and dictatorship; and, on 24 February 1990, Truman’s successor President GHW Bush started secretly to inform America’s European colonies that though the Soviet Union and its communism and its military alliance against America’s NATO, the Warsaw Pact, would likely all soon end, the U.S. side of the Cold War would secretly continue on until Russia itself will be defeated, because, as Bush said to Helmut Kohl, “We prevailed, they didn’t!” In other words, he was telling them to continue on until Russia itself becomes just another U.S. colony like they were, because “we” can do it. He was telling them that “we” will do it, because we can. And none of them objected, because they all would be cut in on the take. But all of this was in blatant violation of repeatedly made verbal promises that the U.S. regime and its agents had made to the Soviet leader Gorbachev that NATO wouldn’t be expanded and take in Warsaw Pact nations if the Soviet Union would break up.

Fast-forward a few more decades, and the U.S. regime invaded a nation that was friendly toward Russia, Iraq, on 20 March 2003, and destroyed it.

On 5 January 2020, Iraq’s Government ordered the U.S. out of Iraq. The Trump regime refused. A reporter for CNN, Manu Raju, tweeted from the Air Force 1 press pool, “Trump … tells pool he will slap Iraq with ‘very big sanctions’ if they force US troops to leave. ‘We have a very extraordinarily expensive air base that’s there. It cost billions of dollars to build. Long before my time. We’re not leaving unless they pay us back for it.’ Trump added: ‘If they do ask us to leave, if we don’t do it in a very friendly basis, we will charge them sanctions like they’ve never seen before ever. It’ll make Iranian sanctions look somewhat tame.’”

The next day, on January 6, Sajad Jiyad of The Century Foundation blogged from Baghdad, “On the issue of US bases, Iraqi sovereignty and sanctions” and reported and presented the legal documents proving that (quoting now from the contract that both Iraq and U.S. had signed) “Iraq owns all the buildings and installations, the nontransferable structures on the ground that are located in the areas and installations agreed upon, including those the U.S. utilizes, constructs, changes or improves.” Furthermore, he noted that, “The US troops that are currently in Iraq are part of a request for assistance to combat ISIS that was sent in 2014. These troops are meant to advise, train and assist Iraqi troops. This request was sent by the Iraqi government and can be revoked at any time.”

On 7 January 2020, Time magazine headlined “Iraq’s Outgoing Prime Minister Says U.S. Troops Must Leave.” Trump responded that only the U.S. Government will decide when to leave Iraq.

On January 24, “The Chief of Police in Baghdad just estimated the number of Iraqis protesting against the US’ presence in Iraq today to be in excess of one million people.” The march in Baghdad was 5 miles long.

On 17 February 2020, I headlined “Trump plans to keep US troops permanently in Iraq under NATO command.” On 24 November 2020, NATO headlined “Denmark assumes command of NATO Mission Iraq.” But Iraqis don’t want any alien military force occupying their country. On 24 February 2021, NATO headlined “NATO Mission in Iraq” and reported, based only upon Iraq’s having requested and received in October 2018 additional training so as to defeat ISIS — that temporary request for training became NATO’s excuse to extend permanently America’s occupation. That NATO report ignored the demand by Iraq’s parliament in January 2020 for all U.S. troops to leave Iraq immediately and ignored the millions of Iraqis who subsequently demonstrated against the U.S. and who demanded the U.S. to leave immediately. (Trump responded to that Iraqi demand by threatening to destroy Iraq if Iraq’s Government would continue its demand.)

And, of course, America’s invasion of Iraq on 20 March 2023 was based totally on lies which the U.S.-and-allied press refused to expose at the time — or even now — to be lies, but instead trumpeted those lies to the public stenographically from the regime’s mouthpieces as being ‘news’. And, likewise, the U.S.-and-allied ‘news’-media hide from their public that the overthrow of Ukraine’s Government during 20-27 February 2014 was a U.S. coup intead of the ‘democratic’ ‘revolution’ they all trumpeted it as being. On 3 July 2023, I headlined “Comparing Two U.S.-Government Catastrophes: Bush’s 2003 Invasion of Iraq, and Obama’s 2014 Coup in Ukraine.”

So: all of this is old news, which is never reported in the U.S.-and-allied press, which instead starts from assumptions that are false about both the Iraq and the Ukraine matters. And the U.S.-and-allied media never apologize to the public about their having lied, because they say that they make only mistakes, no lies. That’s a lie about their lying.

NAFTA 2/USMCA

Adios amigos? What Trump 2.0 means for Canada and Mexico

 not in Canada’s interest to throw Mexico under the bus.

THE CONVERSATION
Published: November 18, 2024

United States President-elect Donald Trump has vowed to implement an across-the-board tariff of at least 10 per cent on all imports into the country.

While there could be some exemptions for American imports of oil, gas and other natural resources, it’s not yet clear whether Canada will be protected by the Canada-United States-Mexico Agreement (CUSMA).

In fact, when the deal comes up for a mandatory review in 2026, Trump has said: “I’m going to have a lot of fun.”

Our mission is to share knowledge and inform decisions.About us

Given that more than 77 per cent of Canada’s exports go to the United States, Canadians have understandably viewed Trump’s declarations with alarm.

And against the likely torrent of American protectionism, Canada has few good options. Responding in kind, for example, will likely lead to a rise in inflation.
Kicking out Mexico?

One idea, recently floated by Ontario Premier Doug Ford, is to abandon CUSMA’s trilateral framework and seek a bilateral Canada-U.S. trade deal. As Ford put it: “We must prioritize the closest economic partnership on Earth by directly negotiating a bilateral U.S.-Canada free trade agreement.”

The premier’s specific complaint is that the Mexican government has failed to prevent the trans-shipment of Chinese goods — especially auto parts and vehicles — through its country in order subvert tariffs imposed by the American and Canadian governments against China.

If Mexico won’t act to prevent trans-shipments or impose its own tariffs on Chinese goods, Ford explained, “they shouldn’t have a seat at the table or enjoy access to the largest economy in the world.”

Ford’s comments drew immediate criticism from Mexican trade officials, but Chrystia Freeland, Canada’s deputy prime minister and finance minister, was more sympathetic. Concerns about Mexican handling of Chinese goods “are legitimate concerns for our American partners and neighbours to have. Those are concerns that I share,” she said.

This is not the first time Canadians have expressed wariness about including Mexico in common North American arrangements.
Canada’s position on Mexico

In 1956, when U.S. President Dwight D. Eisenhower proposed a trilateral summit with Prime Minister Louis St. Laurent and Mexican President Adolfo Ruiz Cortines, Canadian diplomats expressed their opposition to anything that “would appear to equate the relations between the United States and Canada and the United States and Mexico.”

For Ottawa, it was essential to preserve the notion of a special relationship between Canada and the U.S.

Even though the three leaders eventually met in Warm Springs, Ga., the “summit” ultimately consisted of separate U.S.-Canada and U.S.-Mexico bilateral meetings.

Four decades later, Canada pressed to be included in what became the North American Free Trade Agreeement — known as NAFTA — not because of any fellowship with Mexico, but to ensure that its newly won market access to the United States (thanks to the 1988 Free Trade Agreement between the U.S. and Canada) was not undercut by a bilateral Mexico-U.S. deal.
Common front?

As we document in our new book, Canada First, Not Canada Alone, even if Canada’s suspicions of Mexico about trade matters aren’t out of the ordinary, they must be considered against the notion that in dealing with the U.S., there can be strength in numbers

Throughout the early phase of the CUSMA negotiations during the first Trump presidency, Freeland herself was adamant that Canada not abandon Mexico in favour of a bilateral deal.

Rather, she pointedly emphasized the need to work alongside Mexico to present a common front against the Trump administration’s efforts divide its two North American trading partners.

When faced with an overwhelming aggressor, she argued, it’s best not to stand alone.
U.S. made side deal

This position was backed by other ministers as well as by Ottawa’s trade negotiators even as prominent Canadians — including former prime minister Stephen Harper — called for ditching the Mexicans

At first, the Canadian approach appeared to succeed. Freeland herself earned a fearsome reputation among American officials, with Trump attacking her as a “nasty woman.”

Later, however, Canadian negotiators thought they saw an opening and offered the Americans a bilateral deal without notifying their Mexican colleagues.

Not only did Washington reject the offer, American officials approached Mexico City and concluded a separate side deal of their own. This time, it was Canada left unaware.
Warning signs

The threat of being cut out of a trade agreement was more imagined than real — the Trump administration could not replace NAFTA with a bilateral arrangement without congressional approval — but Canada still had to move quickly to restore a trilateral solution.

CUSMA subsequently came into effect on July 1, 2020.

The CUSMA negotiations should offer Ford and the entire Canadian negotiating team a warning.

If Canada is prepared to leave Mexico behind, Canadian officials should be prepared for their Mexican counterparts to do the same. And while it seems right now that the U.S. has problems with Mexico and its management of America’s porous southern border than it does with Ottawa, under the mercurial Trump, the situation can can change in an instant.

It’s therefore probably not in Canada’s interest to throw Mexico under the bus.

Teenage truancy rates rise in English-speaking countries





University College London



Working paper | Quantitative data analysis | People

Truancy rates have risen faster in developed English-speaking countries since the Covid-19 pandemic than in non-English-speaking countries, according to a new working paper by UCL researchers.

Teenage girls are also increasingly more likely to skip school than boys across Anglophone countries.

In 2022, 26% of all Year 11 pupils in England reported playing truant at least once in the last fortnight. This represented an increase from 2012 and 2018, the previous data capture points, when the figure was at 18% each time.

In the same year (2022), 29% of Year 11 girls in England reported skipping school in the past two weeks, compared to 23% of boys. This gender gap was widest in England, the USA, Ireland, New Zealand and Wales.

Teenagers from lower socio-economic backgrounds were more likely to skip school in England. Pre-pandemic, a fifth (21%) admitted to skipping school, compared to 13% for the most advantaged group. This increased in both groups post-pandemic, as nearly a third (29%) of disadvantaged teenagers admitted playing truant in 2022, compared to just over a fifth (22%) of advantaged teenagers.  

The findings, published by UCL’s Social Research Institute, mean the nine Anglophone countries in the developed world have the highest truancy rates for 15-year-olds – and experienced the sharpest rise in rates – out of all OECD countries. The results could have significant policy implications for schools in these countries.

Lead author Professor John Jerrim (UCL Social Research Institute) said: “The increase in Anglophone countries’ truancy rates shows that schools face a huge challenge in re-engaging students and addressing the underlying issues contributing to absences.

“We can attribute the rise largely to girls skipping school more often since the pandemic. It is therefore crucial that we develop and implement targeted interventions to support students and help them stay engaged in their education.”

Wales had the highest gender gap in 2022, with over 40% of girls admitting to truancy, compared to a third of boys.

The researchers also found there was no correlation between the length of school closures during the pandemic and truancy rates. Schools across OECD countries were typically closed for an average of five months, but the authors found no evidence of a direct link between this and the increase in proportion of students skipping school.

For the study, the researchers used data from the OECD Programme for International Student Assessment (PISA), which assesses the academic achievement of 15-year-olds in around 80 countries.

In addition to this, over 200 schools were randomly selected in each country, with around 40 students selected in each school, who were sent a questionnaire about their attendance.

The nine English-speaking countries in the study were England, Ireland, Scotland, Wales, the USA, Australia, Northern Ireland, Canada and New Zealand. The only non-Anglophone OECD countries that experienced a similar increase in truancy since the pandemic are Poland and Italy. The academics say that more research is needed to determine why these two countries have a similar rate to the Anglophone nations.

The researchers speculate that the increase in the proportion of girls skipping schools could be due to rising rates of poor mental health, partly as a result of the Covid-19 pandemic.

Professor Jerrim added: “It is as yet unproven, but possible, that teenage girls could be disproportionately affected by mental health challenges arising in the aftermath of the pandemic, meaning they are more likely to skip school on days when they’re experiencing heightened anxiety.”

The researchers stress that more work is needed to investigate the underlying reasons behind the gender gap in truancy rates.

World's first visual grading system developed to combat microplastic fashion pollution

Over 14 million tonnes of microplastics are estimated to be lying on the ocean floor with the fashion industry among the worst pollutants. 

 

But a new project led by textile experts at Heriot-Watt University in the Scottish Borders, is aiming to make fashion labels and consumers alike, more environmentally aware when manufacturing and buying new clothes. 

 

For four years, a small team headed by Dr Lisa Macintyre, associate professor of textiles at the University’s School of Textiles and Design in the Galashiels campus, has overseen painstaking research to co-develop the world’s first visual ‘fibre fragmentation scale’.

 

The five-point scale assesses the volume of fibre fragments shed from different clothing materials, with observers visually grading each between one and five. Grade one having the highest volume of shed fibres to grade five having the least.

 

This new method is faster and more cost effective when processing a large volume of materials than compared with alternative techniques. This holds significant advantages to manufacturers as they can quickly identify low shedding materials and select these for further testing to determine their suitability for garment production. Existing methods, such as those used by the International Organisation for Standardisation (ISO), are more expensive and time-consuming.

 

The findings have featured in a new paper, entitled, Low-cost, high-throughput quantification of microplastics released from textile wash tests: Introducing the fibre fragmentation scale, and published today in the peer-reviewed journal, Plastics.

 

Dr Macintyre said: “The microplastics problem is massive. Fashion and textiles is one of the biggest sources of secondary microplastics in the environment with fragments of plastic fibres, like polyester and nylon, being shed from clothing.

 

“There are fibre fragments absolutely everywhere, from icebergs to the deepest ocean to human lungs and our food, they’re in everything. 

 

“Visual scales are already used in the fashion industry to measure how much bobbling a material may suffer on its surface for example or, perhaps the most well-known is the grey scale, which measures colour fading or staining, but there was no such tool for fibre shedding. 

 

“This project aims to change that and allow manufacturers to not only make better choices in production but also to communicate to their customers in a very simple and straightforward way, the typical amount of fibres shed from a garment.”

 

Thousands of tiny fibres can be shed from some clothing through daily wear and tear, including laundry. They are typically very thin, ranging in size from a fraction of a millimetre to several centimetres in length. Despite their small size, they can inflict substantial harm on ecosystems, animals, and human health, potentially leading to cellular damage and inflammation.

 

In testing their new scale, the academics used a machine containing eight separate canisters, known as a ‘rotawash’.

 

Textile samples were placed within the canisters, filled with water and then churned to replicate a washing machine cycle. The wastewater was then filtered, allowing the testers and observers to visually grade the shed fibres against the scale.

Some 46 testers from the fashion industry, university students and the public volunteered in the project grading around 100 samples over two years.  

 

Sophia Murden is in her final year studying for a PhD in fibre fragmentation testing at Heriot-Watt University. She has been working alongside Dr Macintyre in developing the fibre fragmentation scale and says this is the first time that a visual scale has been developed. 

 

She said: “Our methodology is simple and cost effective. The filters used to collect fibre fragments from laundry wastewater can be graded against our five-point scale, which surprisingly is more accurate at assessing very low levels of fragmentation than the equivalent method of weighing fibres.

 

“The ultimate aim is for manufacturers to choose materials that are going to have the least impact on our environment but also allow consumers to make an informed decision when they buy their clothing.”

 

If adopted by industry, the fibre fragmentation scale could be displayed on clothing labels, similar to the way many UK food manufacturers display calorie information on packaging.

 

Dr Macintyre adds: “We’ve already been in contact with the likes of Helly Hansen and Lochcarron of Scotland who are very supportive of what we are doing.

 

“The next stage for us is to try and get some kind of industry agreement. Currently, we don’t have an ‘acceptable fragmentation’ rate for clothing but that’s not unusual. The environment is an important issue, and we’d want to get key industry leaders and policymakers to sit down and start agreeing standards, perhaps even legislating against high shedding materials.”

 

The project has been funded through the University’s James Watt Scholarship which is aimed at advancing research for the benefit of society.

Ytterbium  thin-disk lasers pave the way for sensitive detection of atmospheric pollutants

Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the atmosphere precisely, scientists at the Max Planck Institute for the Science of Light (MPL) have developed an advanced laser technology. A high-power ytterbium thin-disk laser drives an optical parametric oscillator (OPO) to generate high-power, stable pulses in the short-wave infrared (SWIR) spectral range. This allows researchers to detect and analyze a wide variety of atmospheric compounds. This novel method can play a crucial role in tracking greenhouse gas cycles and the effects of climate change and was recently published in the journal APL Photonics.

Short-lived pollutants play a critical role in global warming. For example, methane is of particular relevance to the global greenhouse effect because its warming potential is 25 times higher than that of carbon dioxide. However, detecting and monitoring these pollutants is challenging for two reasons. Firstly, water vapor interferes and overlaps with the absorption spectra of many gases in the standard infrared ranges normally used for detection. Secondly, these pollutants are difficult to detect due to their volatile presence in the atmosphere. By targeting the SWIR range, where pollutants such as methane absorb strongly while water absorption remains minimal, the new laser system offers unprecedented detection sensitivity and accuracy.

Central to this innovation is the ytterbium thin-disk laser, which produces high-power, femtosecond pulses at megahertz repetition rates. This allows the system to pump an OPO, converting laser pulses to the SWIR range with remarkable power and intensity. Operating at twice the repetition rate of the pump laser, the OPO delivers stable, tunable SWIR pulses optimized for high-sensitivity spectroscopic applications. The team’s pioneering approach also integrates broadband, high-frequency modulation of the OPO output, which allows the enhancement of the signal-to-noise ratio, providing even greater detection precision.

"The output of our laser system can be scaled to higher average and peak power, due to the power scalability of ytterbium thin-disk lasers. Employing the system for the accurate detection of pollutants in real time allows deeper insights into greenhouse gas dynamics. This could help address some of the challenges we face in understanding climate change." said Anni Li, PhD student at the MPL.

The laser's capacity to generate high-power, stable pulses in the SWIR range is a game-changer for field-resolved spectroscopy and femtosecond fieldoscopy, methods which enable re-searchers to detect and analyze a wide range of atmospheric compounds with minimal interference.

“This new technology is not only applicable to atmospheric monitoring and gas sensing, but also holds potential for other scientific fields such as earth-orbit communication, where high bandwidth modulated lasers are required.” said Dr. Hanieh Fattahi, the lead researcher on the project. The researchers plan to develop the system further with the goal of creating a versatile platform for real-time pollutant monitoring and earth-space optical communications.

Hundreds of 19th-century skulls collected in the name of medical science tell a story

Human Skull (AFP)

When I started my research on the Samuel George Morton Cranial Collection, a librarian leaned over my laptop one day to share some lore. “Legend has it,” she said, “John James Audubon really collected the skulls Morton claimed as his own.” Her voice was lowered so as not to disturb the other scholars in the hushed archive.

As my work progressed, I uncovered no evidence to substantiate her whispered claim. Audubon had collected human skulls, several of which he then passed on to Morton. But birds and ornithology remained Audubon’s passion.

Nevertheless, the librarian’s offhanded comment has proven useful – a touchstone of sorts that continues to remind me of the controversy and confusion long surrounding the Morton Collection.

Morton was a physician and naturalist who lived in Philadelphia from 1799 until the end of his life in 1851. A lecture he delivered to aspiring doctors at the Philadelphia Association for Medical Instruction outlined the reasons for his cranial compulsion:
“I commenced the study of Ethnology in 1830; in which year, having occasion to deliver an introductory lecture on Anatomy, it occurred to me to illustrate the difference in the form of the skull as seen in the five great races of men … When I sought the materials for my proposed lecture, I found to my surprise that they could be neither bought nor borrowed.”

He would go on to acquire almost 1,000 human skulls.

Morton used these skulls to advance an understanding of racial differences as natural, easily categorizable and able to be ranked. Big-brained “Caucasians,” he argued in the 1839 publication “Crania Americana,” were far superior to small-skulled American Indians and even smaller-skulled Black Africans. Many subsequent scholars have since thoroughly debunked his ideas.

Certainly, condemnation of Morton as a scientific racist is warranted. But I find this take represents the man as a caricature, his conclusions as foregone. It provides little insight into his life and the complicated, interesting times in which he lived, as I detail in my book “Becoming Object: The Sociopolitics of the Samuel George Morton Cranial Collection.”

My research demonstrates that studies of skulls and diseases undertaken by Morton and his medical and scientific colleagues contributed to an understanding of U.S. citizenship that valued whiteness, Christianity and heroic masculinity defined by violence. It is an exclusionary idea of what it means to be American that persists today.

Yet, at the same time, the collection is an unintended testament to the diversity of the U.S. population during a tumultuous moment in the nation’s history.

Men of science and medicine

As a bioarchaeologist who has studied the Morton Collection for many years, I have sought to better understand the social, political and ideological circumstances that led to its creation. From my work – analyzing archival sources including letters, laws, maps and medical treatises, as well as the skulls themselves – I’ve learned that, over a lifetime, Morton fostered a professional network that had far-reaching tentacles.

He had plenty of help amassing the collection of skulls that bears his name.

The physician connected with medical colleagues – many of whom, like him, received degrees from the University of Pennsylvania – gentleman planters, enslavers, naturalists, amateur paleontologists, foreign diplomats and military officers. Occupational differences aside, they were mostly white, Christian men of some financial means.

Their interactions took place during a pivotal moment in American history, the interlude between the nation’s revolutionary consolidation and its violent civil unraveling.

Throughout this stretch of time, Morton and his colleagues catalyzed biomedical interventions and scientific standards to more effectively treat patients. They set in motion public health initiatives during epidemics. They established hospitals and medical schools. And they did so in the service of the nation.

Not all lives were seen as worthy of these men’s care, however. Men of science and medicine may have fostered life for many, but they also let others die. In “Becoming Object,” I track how they represented certain populations as biologically inferior; diseases were tied to nonwhite people, female anatomy was pathologized, and poverty was presumed inherited.

From person to specimen

Such representations made it easier for Morton and his colleagues to regulate these groups’ bodies, rationalize their deaths and collect their skulls with casual cruelty from almshouse dissecting tables, looted cemeteries and body-strewn battlefields. That is, a sizable portion of the skulls in Morton’s collections were not culled from ancient graves but belonged to those of the recently alive.

It is no coincidence that Morton began his scientific research in earnest the same year Andrew Jackson signed the Indian Removal Act of 1830. Men of science and medicine benefited from the expansionist policies, violent martial conflicts and Native displacement that underpinned Manifest Destiny.

The collection reveals these acts of nation-building as necropolitical strategies – techniques used by sovereign powers to destroy or erase certain, often already vulnerable, populations from the national consciousness. These skulls attest to precarious existences, untimely deaths and trauma experienced from cradle to beyond the grave.

In the specific case of Native Americans, skeletal analysis testifies to the violent effects of U.S. military campaigns and forced removal. Native skulls that Morton labeled “warriors” have evidence of unhealed fractures and gunshot wounds. Children’s skulls bear the marks of compromised health; such pathology and their young ages at death are evidence of long-standing malnutrition, poverty and deprivation or stress.


To effectively transform subjects into objects – human beings into specimens – collected crania were ensconced in the institutional spaces of medical school lecture halls and museum storage cabinets.

There, Morton first numbered them sequentially. These numbers along with information about race, sex, age, “idiocy” or “criminality,” cranial capacity and provenance were inked on skulls and written in catalogs. Very rarely was the person’s name recorded. If used as teaching tools, Morton drilled holes to hang the skulls for display and notated them with the names of skeletal elements and features.

As dehumanizing as this process was, the Morton Collection does contain evidence of resilience and heterogeneous lives. There are traces of people with mixed-race backgrounds such as Black Indians. Several people may have also bent gender to navigate dire conditions or in keeping with social norms, such as native Beloved Women, who were active in warfare and political life.

What these bones mean today


As anthropologists now recognize, it is through the repatriation of the remains of the people in the Morton Collection to their descendants, among other types of reparations, that current practitioners may begin to atone for the sins of intellectual forebears. Indeed, all institutions housing legacy collections must contend with this issue.

There are other, valuable lessons – about diversity and suffering – that the Morton Collection has to impart in today’s interesting times.

The collection demonstrates that the American body politic has always been a diverse one, despite efforts of erasure by men like Morton and his colleagues. Piecing together the stories of past, disenfranchised lives – and acknowledging the silences that have made it difficult to flesh them out – counters past white nationalism and xenophobia and their current resurgence.

The collection, I believe, also urges the repudiation of violence, casual cruelty and opportunism as admirable attributes of masculinity. Valorizing men who embody these qualities has never served America well. Particularly in the mid-1800s, when Morton amassed skulls, it led to a nation divided and hardened to suffering, an unfathomable death count and the increasing fragility of democracy.
