1953 coup exposed true face of US to Iranian people

American history prof. told MNA


TEHRAN, Aug. 18 (MNA) –Prof. Yaghoubian says, " The US orchestrated 1953 coup itself and subsequent American-enabled abuses of the Pahlavi dictatorship (such as the horrors of SAVAK) exposed the true face of Washington to the Iranian people."

1953 coup in Iran, coup d’état in Iran that occurred in August 1953. Funded by the United States and the United Kingdom, it removed Mohammad Mosaddegh from power and restored Mohammad Reza Shah Pahlavi as Iran’s King. Some 300 people died during fighting in Tehran.

With its strategic location and vast oil reserves, Iran was of special interest to the United States, the United Kingdom, and other powers. Britain had established a presence in the country during World War II to protect a vital supply route to its ally the Soviet Union and to prevent the oil from falling into German hands. After the war, the United Kingdom effectively retained control over Iran’s oil through the establishment of the Anglo-Iranian Oil Company.

This arrangement changed abruptly in 1951 when the Iranian parliament, led by Mosaddegh’s nationalist and democratically elected government, voted to nationalize the country’s oil industry. Seeing its interests thus threatened, the UK embarked on a secret campaign to weaken and destabilize Mosaddegh. At first the British government tried to convince the shah to remove Mossadegh from office by engineering a parliamentary decree, a ploy that both failed and enhanced Mosaddegh’s reputation while diminishing the shah’s. When the push to remove Mosaddegh evolved into the idea of a coup to overthrow the government, Britain, reluctant to shoulder the responsibility alone, persuaded the U.S. to join forces by playing on Cold War fears. 

To know more about the US and the UK goals behind the coup, we reached out to Dr. David Yaghoubian, a Professor of History at California State University, San Bernardino. 

Here is the full text of the interview: 

1953 coup exposed true face of US to Iranian people

What were the goals behind the US and UK orchestrated coup? 

The 1953 coup in Iran was orchestrated to fulfill the goal of the UK and the US to simultaneously crush the oil nationalization movement and replace Iran’s democratically elected government with the dictatorship of the puppet Pahlavi regime. It enabled a consortium of western companies to subsequently control Iranian oil, and Mohamad Reza Pahlavi to remain on the throne to serve foreign interests, against the will of the Iranian people and to their collective detriment. Although the 1953 coup was not intended to sow the seeds of revolution in Iran, ultimately this was its primary accomplishment.

Why was the nationalization of the Iranian oil industry so important for them that they couldn't tolerate Iran's democratic then government? 

As the largest source of crude under the control of the UK, the nationalization of the AIOC in 1951 was intolerable for a dying British empire, which initially resorted to enforcing a global boycott of Iranian oil, before successfully manipulating Cold War fears of the new American presidential administration in 1953 to motivate collective action to carry out the coup. Paralleling Eisenhower administration concerns about potential Soviet interests was a clear desire to exert American control over Iranian oil (and thus over British energy resources) evidenced by the equal US/UK division of spoils via the 1954 consortium. Dividing Iran’s oil wealth among this consortium of foreign companies would never be an acceptable proposition to democratically elected Iranian leadership, thus the coup was designed to implant a compliant and subservient comprador government in Iran to serve overlapping British and American interests.

How has the US-orchestrated coup affected the relations between the two countries since then up to now? 

The 1953 US-orchestrated coup was the crucible of modern Iran-US relations. The coup itself and subsequent American-enabled abuses of the Pahlavi dictatorship (such as the horrors of SAVAK) exposed the true face of the United States government to the Iranian people, who rose up collectively to expel the American Shah, and the tens of thousands of US military advisors and contractors that his regime employed. The success and durability of the Iranian revolution since 1979 simply drives American imperialists mad. Nearly a half century of failed attempts at coercion, bullying, provocation, vilification, global ostracization, and even starvation (according to former US Secretary of State Mike Pompeo) since the revolution have only served to isolate the United States and further point out its rapid decline. Having failed to keep the Iranian nation down via their puppet dictator (1953-1979), failed to destroy Iran via support of the Iraqi Baathists (1980-1988), and subsequently failed to contain, retard, control, or otherwise influence the trajectory of the Islamic Republic and its alliances, US empire has been effectively checked in the region.

Do you see any changes in the colonial policies of the US?  Have they stopped it or just changed the methods?

Rather than changes in colonial policies or employment of different methods I see abject failure, continuity, and self-defeating stupidity on a vast scale, in conjunction with the inexplicable attempt to double down on unsuccessful policies of the past. Until American imperialists can come to grips with the fact that the United States will never achieve global hegemony and “full spectrum dominance,” and that their efforts to promote such US unipolar primacy are demonstrably absurd and counterproductive, the United States will continue to pursue policies and short-term objectives that will ultimately benefit only the military-industrial complex, while hastening the demise of American power, legitimacy, and relevance. Consider American policies that sustained the criminal occupation of Iraq, Syria, and Afghanistan, the carnage in Yemen and Libya, as well as the ongoing attempt to destroy Palestinian society in a wholly US-enabled genocidal project. Murder, destruction, and chaos continue to be the hallmarks of US foreign policy in West Asia. While the more sociopathic members of the American political establishment would claim that these results constitute success in the context of “containment,” area denial, and the twisted concept of “constructive instability,” the US position across the region, physically as well as diplomatically, becomes weaker and more perilous by the day. Its global reputation and legitimacy have never been lower in history. Yet on this 71st anniversary of the 1953 coup in Iran, in light of history and current events—including but not limited to the daily slaughter of Palestinian civilians—what does the United States continue to promote in the region besides more waste, tension, division, conflict, color revolution, war, and genocide? Nothing.

US, UK-backed 1953 coup shattered Iran's democratic process

TEHRAN, Aug. 18 (MNA) – August 19, is the anniversary of the coup d'état that was launched in 1953 by the US and the UK against Prime Minister Mohammad Mossadegh and the democratic process in Iran.

UK, US role in coup d'état; It’s Always About Oil

1953 coup in Iran that occurred in August 1953 funded by the United States and the United Kingdom, removed Mohammad Mosaddegh from power and restored Mohammad Reza Shah Pahlavi as Iran’s king. Some 300 people died during the fighting in Tehrān.

With its strategic location and vast oil reserves, Iran was of special interest to the United States, the United Kingdom, and other powers. Britain had established a presence in the country during World War II to protect a vital supply route to its ally the Soviet Union and to prevent the oil from falling into German hands. After the war, the United Kingdom effectively retained control over Iran’s oil through the establishment of the Anglo-Iranian Oil Company.

Prime Minister Mohammed Mosadegh; Iran's Oil Nationalization

Mohammad Mossadegh became Prime Minister of Iran in 1951 and was hugely popular for taking a stand against the Anglo-Iranian Oil Company, a British-owned oil company that had made huge profits while paying Iran only 16% of its profits and often far less. His nationalization efforts led the British government to begin planning to remove him from power.

In October 1952, Mosaddegh declared Britain an enemy and cut all diplomatic relations. Britain was unable to resolve the issue unilaterally and looked to the United States for help.

US, UK-backed 1953 coup shattered Iran's democratic process

CIA Overthrew Iran's Democracy In 4 Days

The plot, known as Operation Ajax, centered on convincing Iran’s monarch to issue a decree to dismiss Mossadegh from office.

In early August, Iranian CIA operatives threatened Muslim leaders with “savage punishment if they didn't oppose Mossadegh,” thereby giving the impression that Mossadegh was cracking down on dissent.

On August 16, 1953, Mohammad Reza Pahlavi formally dismissed Mossadegh and nominated the CIA’s choice, General Fazlollah Zahedi, as Prime Minister. The decrees were dictated by Donald Wilber, the CIA architect of the plan.

Soon, massive protests, engineered by the US, took place across the city to assist the coup. Mosaddegh was imprisoned for three years and then put under house arrest until he died in 1967.

Anglo-US coup condemned Iran to decades of oppression 

The coup not only encouraged the Shah’s descent towards dictatorship, but it would later become a rallying cry in anti-US protests during the 1979 Iranian Revolution. Even now, Mossadegh is one of the most popular figures in Iranian history.

Indeed, Mosaddeq would not have fallen from power without actions undertaken by Iranians. But it is misleading to elide the US role in the coup, the memory of which continues to continue to haunt US-Iran relations. Even more importantly, the United States played a major role in stabilizing the Shah’s post-coup regime. Focusing on the events of August 19 alone obscures Washington’s ultimate aim with the coup: the return of Iran’s oil resources to foreign control, an objective the United States achieved roughly one year after Mosaddeq’s dramatic fall from power.

Consequences of the 1953 Coup in Iran, West Asia

Iran, West Asia, and, arguably, the whole world may well have been profoundly different. Apart from rewriting the destiny of Iran and its neighbors, the coup paved the way for a series of imperialist interventions and the toppling of democratically elected governments across the global south.

The coup altered the geopolitical landscape in West Asia, became a blueprint for a succession of covert US efforts to foster coups and destabilize governments in the '50s, and provided the Soviet Union with ideological ammunition during the Cold War.
Following the 1953 coup in Iran, the CIA orchestrated the successful Guatemalan coup one year later, failed to oust Syria's president in 1957; and suffered a black eye backing the unsuccessful military invasion of Cuba in 1961.

US, UK-backed 1953 coup shattered Iran's democratic process

CIA publicly acknowledges involvement  in the 1953 coup

For decades, the United States denied playing any part in the Iranian coup. But that position ended in 2009 when President Barack Obama acknowledged Washington's role.

In Britain, meanwhile, the government-funded BBC provided details in 2011 of how it broadcast anti-Mossadegh programs to undermine his government.

Secret files and memoirs of CIA operatives show that the CIA played a pivotal role in initiating and planning Operation Ajax, as the covert operation to oust Mossadegh was called.

On Aug. 19, 2013, the CIA publicly admitted for the first time its involvement in the 1953 coup against Iran's elected Prime Minister Mohammad Mossadegh.

As we saw in the issue of the nationalization of Iran's oil industry and the withdrawal of this national strategic resource from British control, controlling the strategic natural resources of countries has always been one of the motivations of hegemonic powers such as the US to launch endless and multi-dimensional wars against oppressed nations.

Although superiority in the world economy is one of the powerful motivations of the US's involvement in any part of the world, interference in oil-rich countries, countries rich in mineral resources and natural wealth of the world such as Iran, Afghanistan, Iraq, Syria, Venezuela, and Ukraine have always required excuses such as fighting terrorism, defending freedom, guaranteeing security, pre-emptive defense strategy, etc., so that under their protection, the dominating countries, especially US, could implement their policies.

While the US considers itself the observer of other countries to follow all general and common laws, principles, and policies, does not obey these principles and laws

By reviewing the pages of this country's history in the world, there are many cases of violation of common laws and principles in the world by Washington against countries that oppose its policies and even in some cases friends of this country.

Iran court holds 1st trial session over US-plotted 1953 coup




TEHRAN, Aug. 18 (MNA) – An Iranian court has begun the trial of the US administration and its officials over the 1953 coup against the democratically-elected government of Prime Minister Mohammad Mosaddegh.

The first session of the trial was held at the 55th branch of the court dealing with international affairs in Tehran’s Imam Khomeini Judicial Complex on Sunday, on the occasion of the 71st anniversary of the coup.

The court will hear a lawsuit filed by some 402,000 Iranians against six American natural persons and legal enteritis over their role in the ousting of Mosaddegh that consolidated the rule of the pro-Western monarch, Mohammad Reza Pahlavi, until the 1979 Islamic Revolution.

Lawyer Shami Aghdam, representing the defendants, said documents show the US spy agency CIA, with the help of its British counterpart MI6, planned the coup by using internal and external agents against the legitimate government of Iran on August 19, 1953.

Washington and London, it added, “designed the military coup through violating international principles and rules, and interfering in the internal affairs of Iran, intending to maintain their influence and power in the government, securing their interests and looting the country’s property.”

It added that the coup was perpetrated by military and political figures affiliated with the US and the UK governments, as well as thugs.

“In fact, the coup marked the beginning of the US’s complete domination over Iran to make it more dependent than before and prevent its independence and progress. The domination lasted for more than 25 years and inflicted costs, as well as material and spiritual damage, on the country and the nation.”

The 1953 coup set off a series of events, including riots on the streets of the Iranian capital Tehran, leading to the ousting and arrest of Mosaddegh, who was popular in Iran for nationalizing the country’s oil industry and taking it back from largely British control.

It also enabled the return from exile of Mohammad Reza Pahlavi who remained in power until the victory of the Islamic Revolution, led by Imam Khomeini.

Mosaddegh, who was convicted of treason by a court martial after the coup, served three years in solitary confinement and eventually died under house arrest in exile in 1967.

In 2013, the US formally admitted its role in the coup in 2013 with the declassification of intelligence documents.

US to forever be ashamed of overthrowing Mossadegh's govt.

TEHRAN, Aug. 18 (MNA) – Iranian Foreign Ministry Spokesperson stated that the disgrace of overthrowing the popularly elected government of Mohammad Mosaddegh through the 1953 coup will always remain on the face of the US and UK regimes.

On the anniversary of the 1953 coup in Iran, Nasser Kan'ani wrote on his X social account that slavery, colonialism, coups, and military interventions in other countries are only a part of the dark and shameful history of American and British interventions in the world.

The disgrace of overthrowing the popularly elected government of Mohammad Mosaddegh in Iran through the 1953 coup d'état and the political, security, and military support of tyranny will always remain on the face of the US and UK regimes, Kan'ani stated.

He noted that these two countries with such a dark record are currently supporting the fake and racist Israeli regime and the genocide in Gaza, while they consider themselves the flag bearers of human rights and democracy.

DENVER, Aug. 18, 2024 — If you’ve visited a trendy café in the past few years, you might have noticed “golden” turmeric milk on the menu. Though recently advertised as a caffeine-free, healthy coffee alternative, the drink is a fancified version of haldi doodh — a traditional Indian beverage often used as an at-home cold remedy. And now, researchers have developed an efficient method to make a plant-based, instant version that maintains the beneficial properties of the ingredients while also extending its shelf life.

The researchers will present their results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2024 is a hybrid meeting being held virtually and in person Aug. 18-22; it features about 10,000 presentations on a range of science topics.

Golden milk — also called golden or turmeric latte — consists of milk, turmeric and spices, and is a good option for people who want to avoid caffeine or coffee or maybe enjoy a unique flavor. “It’s a very good beverage, especially if it’s cold outside, or if you’re sick,” explains Anthony Suryamiharja, a graduate student at the University of Georgia who’s presenting the research at the meeting. He says turmeric also features the bioactive compound curcumin — a polyphenol that has been studied for its potential anti-inflammatory and antioxidant effects. “If we can incorporate bioactive compounds like curcumin into plant-based milks to bring them up to the same nutritional level as cow’s milk, why not?” asks Suryamiharja.

Curcumin, however, is difficult to separate from turmeric, typically requiring complicated extraction techniques that involve organic solvents, multiple days and lots of energy. In addition, the compound tends to break down over time, shortening its shelf life. So, inspired by golden milk, Suryamiharja, Hualu Zhou and colleagues wanted to investigate whether there was a way to extract and store curcumin within plant-based milk.

They first added turmeric powder to an alkaline solution, where the high pH made the curcumin more soluble and easier to extract than in plain water. This deep red solution was then added to a sample of soy milk, turning it a dark yellow color. They brought it down to a neutral pH around 7. Just like low-pH acids, high-pH bases are not the most pleasant things to consume. The neutralized pseudo-golden milk could be enjoyed as-is, but to further preserve it, the team removed the water from the solution through freeze-drying, producing an instant golden milk powder.

Not only does the method extract curcumin from turmeric more efficiently than existing methods, but it also encapsulates the curcumin in oil droplets within the soy milk. This means that when consumed, our bodies recognize the curcumin as fat and digest it as such, theoretically making the curcumin more bioavailable, or likely to be absorbed and able to have an effect in the body. Encapsulating the curcumin also protects it from air and water, preserving it and keeping it shelf-stable for longer.

While this work focused specifically on soy milk because of its high amino acid content, the researchers say that it could be applied to other plant-based milks, providing options for those with allergies to soy. In addition, their pH-driven extraction method could be used on different plant compounds with similar ease and efficiency. For example, blueberries are rich in anthocyanins, another water-soluble polyphenol. “When we use the same method, within around a minute we can extract the polyphenols,” explains Zhou. “We want to try and use it to upcycle by-products and reduce the food waste from fruit and vegetable farming here in Georgia.”

Though more research is needed before their instant golden milk appears on store shelves, the researchers’ initial result is promising — Suryamiharja reports that it tasted good, despite not being a frequent golden latte enjoyer himself.

The team hopes that this work can help explain the chemistry behind what may seem like nothing more than a simple beverage, as well as improve that drink’s nutritional value and convenience for those who enjoy it. Suryamiharja explains that “people usually do a lot of simple things in the kitchen, but they don’t really realize there’s a chemistry behind it. So, we’re trying to explain those unspoken things in a simple way.”

The research received startup funding from the Department of Food Science & Technology at the University of Georgia.

Title
Utilizing a green pH-driven approach for developing curcumin-infused soymilk

Abstract
With the global population projected to reach approximately 10 billion by 2050, there is a urgent need for sustainable, healthy, and affordable next-generation foods to meet increasing demand. However, fully harnessing the potential of plants to enhance the sustainability and health benefits of plant-based ingredients or foods remains challenging, particularly in the absence of efficient and cost-effective processing methods. In this study, we developed a novel two-in-one approach, termed the post pH-driven (PPD) method, to simultaneously extract and encapsulate curcumin in plant-based milks. This innovative technique offers a highly efficient and economical means of incorporating bioactive curcumin or turmeric for enhanced health benefits. Using soy milk as a model system, we initially dissolved curcumin or turmeric in an aqueous extraction solution. Subsequently, the dissolved compounds were directly encapsulated into the hydrophobic phase of soymilk. Finally, the mixture was processed into milk powder, achieving exceptional extraction and encapsulation efficiencies of approximately 100% for curcumin and 80% for turmeric. The slightly lower efficiency observed for turmeric can be attributed to the fact that only approximately 80% of curcumin was extracted, while its encapsulation efficiency approached 100%. Moreover, the resulting curcumin-infused milk powder exhibited high water solubility due to the encapsulation of curcumin within the hydrophobic phase of soymilk. Additionally, the chemical stability of curcumin was significantly enhanced. The successful infusion of curcumin or turmeric can be attributed to the rapid and efficient processing enabled by the PPD approach. Moreover, this method is noteworthy for its avoidance of organic solvents and sophisticated equipment, resulting in a reduced environmental footprint. Overall, the PPD approach holds significant promise for driving innovation in the development of plant-based foods.

DENVER, Aug. 18, 2024 — If you come across brightly colored, cloth-bound books from the Victorian era, you might want to handle them gently, or even steer clear altogether. Some of their attractive hues come from dyes that could pose a health risk to readers, collectors or librarians. The latest research on these poisonous books used three techniques — including one that hasn’t previously been applied to books — to assess dangerous dyes in a university collection and found some volumes may be unsafe to handle.

The researchers will present their results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2024 is a hybrid meeting being held virtually and in person Aug. 18-22; it features about 10,000 presentations on a range of science topics.

“These old books with toxic dyes may be in universities, public libraries and private collections,” says Abigail Hoermann, an undergraduate studying chemistry at Lipscomb University. Users can be put at risk if pigments from the cloth covers rub onto their hands or become airborne and are inhaled. “So, we want to find a way to make it easy for everyone to be able to find what their exposure is to these books, and how to safely store them.” Hoermann, recent graduate Jafer Aljorani, and undergraduate Leila Ais have been conducting the study with Joseph Weinstein-Webb, an assistant chemistry professor at Lipscomb.

The study began after Lipscomb librarians Jan Cohu and Michaela Rutledge approached the university’s chemistry department to test brilliantly colored 19th- and early-20th-century fabric-covered books from the school’s Beaman Library. Weinstein-Webb was intrigued to hear about how the Winterthur Museum, Garden & Library had previously examined its own 19th-century books for the presence of an arsenic compound known as copper acetoarsenite. This emerald-green pigment was used in Victorian era wallpaper, garments and — as Winterthur found out — in cloth book covers. This discovery led to the launch of the Poison Book Project, a crowdsourced research effort that uses X-ray fluorescence (XRF), Raman spectroscopy and other techniques to reveal toxic pigments in books around the world.  Weinstein-Webb and the Lipscomb students he recruited launched their own investigation in 2022.

For the Lipscomb book project, the team used three spectroscopic techniques:

  • XRF to qualitatively check whether arsenic or other heavy metals were present in any of the book covers.
  • Inductively coupled plasma optical emission spectroscopy (ICP-OES) to determine the concentration of those metals.
  • X-ray diffraction (XRD) to identify the pigment molecules that contain those metals.

Although XRD has been previously used to examine paintings and wallpaper, this is the first time it has been used to check for poison in books, Ais says. The XRD testing is being done in collaboration with Janet Macdonald at Vanderbilt University.

Recently, the researchers used XRF data to show that lead and chromium were present in some of the Lipscomb books. To quantify the amounts, they snipped samples roughly the size of a small paperclip from the cloth covers and then dissolved them in nitric acid. Their analysis by ICP-OES showed that lead and chromium were both present at high levels in some samples. Subsequent XRD testing indicated that in some instances these heavy metals were in the form of lead(II) chromate, one of the compounds that contributes to the chrome yellow pigment favored by Vincent van Gogh in his sunflower paintings.

However, there was far more lead than chromium in the book covers, which is somewhat mystifying, since lead(II) chromate contains equal amounts of lead and chromium. The researchers speculate that the dyes used to color the books contain other lead-based pigments that lack chromium, such as lead(II) oxide or lead(II) sulfide. The team is working to identify those other compounds in the yellow pigments.

Weinstein-Webb and the students also wanted to find out whether the levels of heavy metals in the Lipscomb books could be harmful for librarians who might handle them. For some of the book covers, the researchers discovered metal concentrations above acceptable limits for chronic exposure, according to standards set by the Centers for Disease Control and Prevention (CDC). In the dissolved sample from the most contaminated cover, the lead concentration was more than twice the CDC limit, and the chromium concentration was almost six times the limit. Chronic exposure to inhaled lead or chromium could lead to health effects such as cancer, lung damage or fertility issues.

“I find it fascinating to know what previous generations thought was safe, and then we learn, oh, actually, that might not have been a great idea to use these brilliant dyes,” Weinstein-Webb says.

The findings led the Lipscomb library to seal colorful 19th-century books that have not yet been tested in plastic zip-close bags for handling and storage. Meanwhile, books confirmed to contain dangerous dyes have also been sealed in bags and removed from public circulation.

Once the researchers have done some more testing, they plan to contribute their results to the Poison Book Project and to help spread awareness on safe handling, conservation and storage of these books among librarians and collectors.

They also hope others will follow their lead and begin using XRD, because it doesn’t require investigators to cut samples from books. “Moving forward,” says Hoermann, “we want libraries to be able to test their collections without destroying them.”

The research was supported by funds from Lipscomb University’s chemistry department.

Title
Multimodal detection of toxic metals in Victorian era book cloths as part of the Beaman library collection

Abstract
In the nineteenth century, textile manufacturing during the Victorian Era involved usage of heavy metals and carcinogenic amines in the production of book-cloth case bindings, posing potential risks to both environment and biological health. These fabrics encompass a range of vivid hues; the highly toxic pigment emerald green (copper acetoarsenite), non-arsenical chrome yellow (lead (II) chromate PbCrO4), or a mixture of Prussian blue (hydrated iron hexacyanoferrate complex Fe4[Fe(CN)6]3 . x H2O). Utilizing inductively coupled plasma–optical emission spectroscopy (ICP-OES) and portable X-ray fluorescence (pXRF), preliminary research has revealed more than 100 rare circulating books containing these toxic dyes. The purpose of this study is to detect and quantify levels of arsenic, copper, chromium, lead, and manganese in local books utilizing ICP-OES and any applicable optical modality. In the end, we hope to contribute to the larger Winterthur Project. Through this, elevated levels of harmful metals, specifically lead (II) chromate, were confirmed within the Beaman Library collection via ICP-OES.

A tiny battery designed by MIT engineers could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines.

The new battery, which is 0.1 millimeters long and 0.002 millimeters thick — roughly the thickness of a human hair — can capture oxygen from air and use it to oxidize zinc, creating a current of up to 1 volt. That is enough to power a small circuit, sensor, or actuator, the researchers showed.

“We think this is going to be very enabling for robotics,” says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and the senior author of the study. “We’re building robotic functions onto the battery and starting to put these components together into devices.”

Ge Zhang PhD ’22 and Sungyun Yang, an MIT graduate student, are the lead author of the paper, which appears in Science Robotics

Powered by batteries

For several years, Strano’s lab has been working on tiny robots that can sense and respond to stimuli in their environment. One of the major challenges in developing such tiny robots is making sure that they have enough power. 

Other researchers have shown that they can power microscale devices using solar power, but the limitation to that approach is that the robots must have a laser or another light source pointed at them at all times. Such devices are known as “marionettes” because they are controlled by an external power source. Putting a power source such as a battery inside these tiny devices could free them to roam much farther.

“The marionette systems don’t really need a battery because they’re getting all the energy they need from outside,” Strano says. “But if you want a small robot to be able to get into spaces that you couldn’t access otherwise, it needs to have a greater level of autonomy. A battery is essential for something that’s not going to be tethered to the outside world.”

To create robots that could become more autonomous, Strano’s lab decided to use a type of battery known as a zinc-air battery. These batteries, which have a longer lifespan than many other types of batteries due to their high energy density, are often used in hearing aids. 

The battery that they designed consists of a zinc electrode connected to a platinum electrode, embedded into a strip of a polymer called SU-8, which is commonly used for microelectronics. When these electrodes interact with oxygen molecules from the air, the zinc becomes oxidized and releases electrons that flow to the platinum electrode, creating a current.

In this study, the researchers showed that this battery could provide enough energy to power an actuator — in this case, a robotic arm that can be raised and lowered. The battery could also power a memristor, an electrical component that can store memories of events by changing its electrical resistance, and a clock circuit, which allows robotic devices to keep track of time.

The battery also provides enough power to run two different types of sensors that change their electrical resistance when they encounter chemicals in the environment. One of the sensors is made from atomically thin molybdenum disulfide and the other from carbon nanotubes.  

“We’re making the basic building blocks in order to build up functions at the cellular level,” Strano says.

Robotic swarms

In this study, the researchers used a wire to connect their battery to an external device, but in future work they plan to build robots in which the battery is incorporated into a device.

“This is going to form the core of a lot of our robotic efforts,” Strano says. “You can build a robot around an energy source, sort of like you can build an electric car around the battery.”

One of those efforts revolves around designing tiny robots that could be injected into the human body, where they could seek out a target site and then release a drug such as insulin. For use in the human body, the researchers envision that the devices would be made of biocompatible materials that would break apart once they were no longer needed.

The researchers are also working on increasing the voltage of the battery, which may enable additional applications.

The research was funded by the U.S. Army Research Office, the U.S. Department of Energy, the National Science Foundation, and a MathWorks Engineering Fellowship.

Perceived parental distraction by technology and mental health among emerging adolescents



JAMA Network



About The Study:

In a cohort study of 1,300 emerging adolescents ages 9 to 11 across three assessments, higher levels of anxiety symptoms were associated with higher levels of perceived parental technoference later in development. Higher levels of perceived parental technoference were associated with higher levels of inattention and hyperactivity symptoms later in development. The findings of this study speak to the need to discuss digital technology use and mental health with parents and emerging adolescents as a part of routine care.

New research from Smithsonian’s Bird Friendly Coffee program highlights a type of biodiversity that often gets overlooked: soil bacteria and fungal communities. For over twenty years, Smithsonian research has shown that coffee farms with shade trees protect more biodiversity than intensified, monoculture coffee farms. The new research, published today in Applied Soil Ecology, shows that soil bacteria and fungi on coffee farms also respond to the intensity of coffee farm management. To conduct this research, the team collected soils samples on coffee farms in Colombia, El Salvador, and Peru and used DNA analysis to profile bacterial and fungal soil on farms with different management regimes. They found that farming coffee as a monoculture alters the soil microbiome in both community composition and species diversity. But not all shade-grown coffee farms were the same. The soil microbiomes on farms with native shade trees was different than on farms with non-native, introduced species of shade trees as well. Soil microbiomes in the tropics are poorly understood, and this research demonstrates the incredible diversity within soils in tropical agricultural landscapes across Latin America. This research also furthers our understanding of how coffee farm management decisions impact that entire agricultural ecosystem, which in turn impacts the production of coffee and the livelihoods that depend on it. As biodiversity is declining globally at an alarming rate, agricultural landscapes can play an important role in conserving unique species and ecological processes that enable agriculture to thrive.
