This research provides key insights into how microbial inoculants can offer a cost-effective, eco-friendly strategy to enhance crop resilience in saline soils.

Soil salinization is a major global challenge that severely impacts agricultural productivity, with over 3% of the Earth’s terrestrial surface affected. It threatens food security by causing osmotic, ionic, and oxidative stress, which can reduce crop yields by more than 50%. Traditional remediation methods, such as physical and chemical interventions, are often prohibitively expensive. However, microorganisms, particularly endophytic fungi, have shown promise in enhancing plant growth and resilience under salt stress. These fungi, which live inside plant tissues without causing harm, have been found to help plants adapt to extreme environmental conditions, including salinity. Researchers are increasingly turning to beneficial microorganisms as a sustainable solution to mitigate salt stress in plants.

A study (DOI: 10.48130/tp-0025-0005) published in Tropical Plants on 19 March 2025 by Yanping Hu and Yang Zhou’s team, Hainan University, offers a cost-effective, environmentally friendly alternative to costly soil amendments.

In this study, 426 cultivable root endophytic fungi (EF) were isolated from 1,180 tissue blocks of Sesuvium portulacastrum using a tissue block method. These fungi were subjected to sequencing and analysis through the Basic Local Alignment Search Tool (BLAST) in the NCBI database, resulting in the classification of 426 sequences into 112 distinct operational taxonomic units (OTUs). The diversity indices of EF across 20 sampling sites varied significantly. The Shannon-Wiener index showed the highest diversity in regions such as HK-BS (2.45), and the Simpson index was highest in QH-GH (0.91). Fusarium was identified as the most prevalent genus, followed by Pleosporales and Monosporascus. A plate screening method was used to assess salt tolerance, revealing that eight EF strains, including LG-BZ-9, showed enhanced growth under saline conditions, with colony diameters 1.6 to 1.8 times larger than the control. Strain LG-BZ-9 was further evaluated for its effects on maize growth under salt stress. Results showed that maize treated with LG-BZ-9 exhibited significantly improved growth, including increased fresh weight, plant height, and chlorophyll content, compared to untreated plants exposed to 250 mM NaCl. Additionally, LG-BZ-9 treatment led to a higher potassium (K+) concentration and lower sodium (Na+) concentration in maize tissues, improving the K+/Na+ ratio and enhancing the plant's salt tolerance. These findings suggest that salt-tolerant EF such as LG-BZ-9 can improve maize growth and salt tolerance by modulating ion homeostasis, offering a promising approach for enhancing crop resilience in saline environments.

This study demonstrates the promising role of endophytic fungi from halophytes in enhancing the salt tolerance and growth of maize under saline conditions. By improving ion balance and modulating plant growth, F. incarnatum LG-BZ-9 offers a potential solution for sustainable crop production in saline-affected regions. These findings lay the groundwork for the development of microbial-based agricultural strategies that can support global efforts to combat soil salinization and ensure food security in the face of environmental challenges.

Board game enables autistic people to create stories about their condition



Researchers found the illustrated cards used in Dixit helped evoke emotions in a way that could bridge the gaps between people with and without autism




University of Plymouth




A board game through which players use images on cards to develop and tell their own stories could be particularly appreciated among people with autism as it offers a means to explain their thoughts and feelings, a new study has shown.

Dixit, an award-winning game published by the French company Libellud, invites participants to select one of 84 illustrated cards which they feel matches a title suggested by the designated storyteller.

For this study, researchers asked 35 autistic participants – split into groups of between five and eight – to place a card that they felt best described autism, and then being asked to explain the reasoning for their choices.

Analysing the responses, the researchers found the cards placed by participants covered three main themes:

  • Challenges – where participants chose cards that spoke to the difficulties experienced by neurodiverse people, including symptoms of autism and their effects that resulted in anxiety and exclusion;
  • Strengths – where participants chose cards that spoke to the unique traits of autistic people that make them excel in certain areas;
  • Society – through which participants highlighted how people’s perceptions of autism created a divide between autistic and neurotypical people that exacerbated any challenges they may already experience.

Based on this, the researchers say that playing Dixit could be particularly effective for autistic people since rather than having to come up independently with inspiration, participants could use the cards to evoke emotions about their condition.

They also believe it and similar games could go some way to creating a conducive environment for learning about different life experiences, bridging the gap between autistic and neurotypical people.

The study was published in Discover Psychology, and led by Dr Gray Atherton and Dr Liam Cross from the School of Psychology at the University of Plymouth.

Dr Atherton, the new study’s lead author, said: "Sometimes it can be hard to find the words to explain something personal and complicated. That can include how what it feels to have a condition like autism, that comes with lots of stereotypes and misperceptions. Opening up about this by playing a game, and then being able to use images to support your words, may be a real breakthrough.”

Dr Cross added: “This study adds further evidence to the idea that gamified approaches might make it easier for people to talk about difficult topics. In terms of double empathy, or the ability for people with and without autism to understand each other's lived experience, Dixit could be an important step in forming these relationships between groups. We are currently following up on this with schools to see if children can use it to more easily talk about complex topics like grief, bullying and divorce."

Dixit was one of several games played in community groups for autistic adults across the UK as part of a larger study, also led by Dr Atherton and Dr Cross, on the connections between autism and board gaming.

Previous publications as part of the same programme of research have showed that people with autism are overrepresented in the board gaming community compared to the general population, and that they felt playing modern board games provided a social outlet in a structured space.

 

‘A love affair with the sea’: Meet a scientist who overcame hurdles to dedicate her life to studying the ocean

by Dr Mary Elizabeth Livingston

In my recently published paper ‘My love affair with the sea’ I describe how from a very early age I fell in love with the sea and pursued that love throughout my younger years and at university, ending up with a 40-year career as a fisheries scientist. Political changes on how women were perceived in the workplace benefitted me and I feel incredibly lucky to have had the opportunity to work in a job that has taken me to many parts of the globe and given me such a purposeful way of contributing to human and ecological wellbeing.

I am originally from the UK but moved to New Zealand as a post-graduate student in 1976. I ended up staying in this remote corner of the planet, and in 2022, I retired. But my love affair with the sea is as strong as it ever was. These days, I can be seen on the south coast of Wellington with my camera in hand trying to capture the moods and whims of the sea in Cook Strait.

Barriers to success

I believe that the stresses on women in fisheries science during my early career in the 1970s and 80s (and other related disciplines such as observers, fisheries, management, industry) were particularly great. Then, at sea and in the field, women scientists entered the world of men in New Zealand. Not only did we work in a male dominated field, but in New Zealand at least, there was a highly charged polarization between industry and conservation, which added an underlying complexity. For example, not only did I find that women at sea had to prove themselves time and again as being ‘one of the boys’, but further, we were automatically seen as ‘greenies’ or ‘bottom feeders’ - a term for creatures living on the seabed – which made it harder to work through. But, on almost every survey, there would be at least two women on the science team, and we supported each other fervently.

Lodging complaints was very difficult to do, and was not seen as a way to achieve co-operative working conditions. Biases also occurred ashore in the science institutions, but we became good at holding our own when attending science meetings and the like. It may well be that the same issues occurred across other western countries, but my experience is that in Australia, the US, the UK, Scandinavia, the EU, and Chile, fisheries science was better supported, with strong infrastructure and decision-making mechanisms, compared with New Zealand.

We had a small research vessel, RV ‘James Cook’ that was really quite unsuitable for New Zealand’s offshore waters, so we made do with chartering large research and commercial fishing vessels from other nations. Cultural and language barriers added to the challenges that we faced at sea (men and women) but more often than not, the women were better at appeasing the foreign skippers. By this I mean we demonstrated considerably higher emotional intelligence which helped smooth the pathway for successful surveys and robust data collection while on board.

A change in direction

Things did improve during the latter part of my career. Management practices became far more family friendly, and I really benefited from that. For example, my new employers were highly supportive regarding career opportunities for women and built an on-site childcare center for us to use – all part of the Equal Employment Opportunity focus of the times. At sea, more robust disciplinary processes to protect women were introduced and more serious thought was given to ensuring that women in all aspects of fisheries science were better heard.

I maintain that while there is always room for improvement regarding male-female equality, the bigger issues facing women in fisheries science today are lack of funding for the scientific monitoring and understanding of stock sustainability, and the lack of political will to champion broader investigation about oceanic ecosystems and the biological limits to wild caught fisheries. Numerous in-depth reviews have provided suggestions on how to bring together indigenous rights, science, industry, aquaculture, recreational fishers, and government, but so far, the infrastructure and commitment has not been forthcoming.

In conclusion I feel extremely lucky to have had such an interesting and challenging career. Being female can even be advantageous, but this sort of career is not for the faint-hearted. A passion for the ocean and for looking after the animals that live in it was a key part to how I kept going.

Marx Matters in a Deeply Unequal World in Crisis

Capitalism is crisis banner at The World Transformed. Photo credit: The World Transformed

“Marx once said that ‘the rich will do anything for the poor but get off their backs.’ This remains true in today’s world.”

By Jon Trickett MP

Idly overhearing a conversation about class and economics between two Labour people in Parliament the other day I got to thinking about whether Marx is still relevant. One of the two people said something like “Oh, he’s an old fashioned socialist.  Thinks that Karl Marx remains relevant to what’s happening in the world today.”

I think they were talking about the American politician Bernie Sanders. Of course, Karl Marx may have lived in the 19th century, and the world has self-evidently changed a great deal over time. But his analysis of the economic structures of capitalist economies often feel as if they were written yesterday. 

He didn’t live to witness the rise of tech billionaires, global financial derivatives, or FTSE-100 CEOs earning in a day what most workers earn in a year – but he didn’t need to. He understood capitalism’s structures: its ruthless logic of accumulation, its division of society into classes, and its tendency to generate enormous wealth for a few alongside hardship for the many.

Marx once said that “the rich will do anything for the poor but get off their backs.” This remains true in today’s world. We live in a time when the five richest men on Earth have more than doubled their wealth since 2020 – rising from $405 billion to $869 billion – while nearly five billion people have seen their wealth decline. That’s not just unfair. It’s the global system doing exactly what Marx said it would do.

In Britain, nearly a third of all children – about 4.3 million – live in poverty. Globally, 333 million children are trapped in extreme poverty, and nearly a billion face multidimensional poverty: no basic access to clean water, food or  education. This isn’t misfortune. It is the result of global economic policy – a system of exploitation that Marx would recognise all too well.

Marx argued that capitalist societies are divided by class: those who own and control the means of production and those who do not. That fundamental divide hasn’t gone away. If anything, it’s become more obvious. Today, seven out of the ten largest corporations in the world are run by billionaires. These corporations control $10.2 trillion – more than the combined GDPs of all countries in Africa and Latin America.

In Britain, the top 50 families own more than the wealth of 34 million citizens combined. Meanwhile, the average salary is around £37,500 – a sum a FTSE CEO earns in less than 30 hours. In the face of such glaring inequality, even the mildest proposals for a wealth tax are met with fierce resistance by some of those with the most to lose.

And what about our tax system? It taxes income from work more heavily than income from capital. In other words, someone who works a 40-hour week pays a higher tax rate than someone who earns millions off dividends and shares. This isn’t an accident. It reflects Marx’s understanding of the modern state as an instrument of bourgeois class rule – the machinery of government defends the interests of capital over labour.

In the current cost of living crisis, millions of working class people are struggling to get by. As rent, energy bills, and food prices soar, we can see the world through Marx’s eyes. He couldn’t foresee every detail of today’s highly financialised tech capitalism, but he didn’t need to for his work to remain relevant. His analysis gives us a powerful lens to understand why, in one of the wealthiest countries in the world, children go hungry while billionaires multiply.

Perhaps the most relevant part of his critique of capitalist economics was his view of its dynamics. We can all perhaps agree that extreme inequality is unwelcome.  

But Marx proposes that the extreme wealth of some comes at the expense of the poverty of others: the ‘accumulation of wealth at one pole is at the same time the accumulation of misery, agony of toil ….at the opposite pole.’

The Left’s call for a more equal society and an economy that serves the many and not just the few, are not relics of the past. They are urgent demands rooted in an understanding that, in a capitalist system, inequality is not a temporary imperfection. It’s a permanent feature.

Marx’s legacy isn’t just in what he got right. It’s also in how he challenged us to ask who owns our world, who profits, and who pays the price. That challenge remains as relevant now as it was 150 years ago.




“The struggle never stops”



Mike Phipps reviews Global Battlefields: Memoir of a Legendary Public Intellectual from the Global South, by Walden Bello, published by Clarity.

As one of this book’s many endorsements points out, “The name ‘Walden Bello’ is virtually synonymous with the struggle for global social justice.” Activist, academic and Philippines politician, Bello, who will be eighty this year, covers a phenomenal range of activity in this memoir.

Yet it nearly didn’t get written. Bello admits at the outset that he feels like a failure: the two big movements he was involved in, the Philippines left and the international movement for socialism, both failed to realise their potential: “Traditional elite politics reigns supreme and unchallenged in our country and capitalism lurches on drunkenly but similarly unchallenged globally.”

But as the late Mike Marqusee argued, “You can learn more from a failure than from a success – if you recognise it as such.” Looking back, Bello feels that the failures he experienced were perhaps merely “setbacks in a longer-term enterprise.” In any event, we can be thankful that he decided to write this illuminating memoir.

Vietnam and Chile

He was born on an island in the middle of the Philippines’ largest lake to artistic parents and was schooled by the Jesuits. After graduating, he was sacked from his first two jobs, as a college professor and associate editor of a provincial newspaper, for offending two religious establishments—the Christian and the Muslim—with his writing. But his real radicalization began at Princeton University, which was “convulsed by struggles over racism, women’s rights, capitalism, and above all Vietnam, as was the rest of the United States.” Bello was arrested on a sit-down protest on campus but escaped deportation. One wonders how he would have fared today. Later he played a leading role in taking over and shutting down Princeton’s school of public administration as part of the anti-war campaign.

In 1971, impressed by the radical changes taking place under the democratically elected Socialist government of Salvador Allende in Chile, he decided to study events there for his PhD. He soon realised that the revolution was on the defensive, and the right were beginning to take command of the streets. He decided to focus his studies on the rise of the Chilean counter-revolution and how the Popular Unity government had failed to win over the pivotal middle classes. He concluded that, in the 1973 Chilean coup, the US intervention was successful “because it was inserted into an ongoing counterrevolutionary process that had its base in the middle class. CIA destabilization efforts were just one of the factors that contributed to the victory of the right, and not the decisive one. This was not something that progressives wanted to hear then,” observed Bello and he never published his work.

Organising against Marcos

In September 1972, the Marcos regime declared martial law in the Philippines. “Over the next 14 years, thousands were imprisoned, tortured, or extra-judicially executed under a dictatorship that can best be described as a predatory, kleptocratic state. During those 14 years, bringing down that regime became my raison d’être.”

Bello worked in the Union of Democratic Filipinos (KDP) which brought together activists influenced by the ongoing armed revolution in the Philippines with second generation Filipino-Americans who were politicized by housing and union struggles in the US. He joined the Communist Party of the Philippines and over the next 15 years “was a disciplined member of this organization, forsaking a steady job, sleeping on the couches of comrades’ homes, crisscrossing the U.S. on cheap ‘red-eye’ flights from which I would emerge totally exhausted, subsisting on Doritos and burritos and cigarettes.” His commitment eroded his marriage and brought him into confrontation with the repressive apparatus of the state.

In 1978, he took part in the nonviolent takeover of the Philippine Consulate in San Francisco to protest against rigged elections in his home country, an action for which he lost his teaching job at the City College of San Francisco. He and his comrades refused to recognise the authority of the court which subsequently found them guilty of criminal trespass. They began a hunger strike in jail, which succeeded in getting them released.

Later he and others broke into the World Bank headquarters and stole 6,000 pages of documents that showed the many connections of the IMF and World Bank to the Marcos regime. The contents were written up in Development Debacle, which became an underground bestseller in the Philippines and arguably contributed to the later downfall of the dictatorship.

In 1981, he helped organise a protest against Imelda Marcos, the wife of the Philippines dictator, who was visiting the John F Kennedy Center for the Performing Arts – the first ever at that venue. He and his comrades dressed up in their finest outfits, having paid a small fortune for the best seats from which to unveil banners condemning the dictatorship and get the spotlight. Other innovative protests followed.  

The left marginalised

The 1983 assassination of Ninoy Aquino, the main leader of opposition to Marcos, by agents of the regime, invigorated the middle class opposition, who now began to distance themselves from the left, sidelining the National Democratic Front and other organisations the left had constructed.

The Reagan Administration was quick to adapt and began to apply pressure to get Marcos to share power. In the 1986 presidential elections, in which the US was now aiming to engineer an opposition win, the NDF misread the public mood and unwisely called for a boycott, marginalising itself. As Marcos announced a fraudulent victory and thousands took to the streets, the US finally pressurised the dictator to go.

“The new liberal democratic regime had a contradictory character,” writes Bello. “It was certainly open and democratic, but the military took advantage of its legitimacy to repress the Left, which could no longer depend on the liberal elite and the middle class to defend it.”

The author got his first full-time job in thirteen years, researching at Food First in San Francisco. His analysis of the flexibility of the new Philippines formal democracy diverged from the Communist Party, which had not updated its line. The Party, concerned about its penetration by military agents, also began massive purges – including the execution of thousands of its members, the full story of which could be pieced together only later.

The Party itself later recognised the purges as “madness”, but beyond the lack of common sense or proper controls within the organisation, Bello felt something else was responsible: “Marxism’s very instrumental view of people, that is, its lack of a developed concept of individual rights; in other words, it saw individuals as having rights only by virtue of their membership in the right classes, or, failing that, their holding the right politics. Thus, if an individual is suspected or judged to be a ‘class enemy,’ he or she does not have an innate right to life, liberty, and respect, and what happens to her depends purely on the tactical needs of the moment.”

The fratricidal purges hugely reduced the Communists’ influence in the country. Bello’s own analysis of it was denounced as “bourgeois” and he left the Party at the end of the 1980s.

Return to Southeast Asia: Anti-globalization activism

Bello remained an activist and was now able to think more creatively. Studying US policy towards countries in the Global South, he concluded that the key consideration “as to its preference for a type of political regime was preventing the Left from coming to power, and if either authoritarianism or liberal democracy failed to secure this, then there was still the final solution: military intervention.”

His job, and his comparative studies of structural adjustment and newly industrializing countries, took him across southeast Asia and allowed him to forge lasting links with worker and student activists. In 1994, he moved permanently back to Asia, joining  the faculty of the University of the Philippines at Diliman and co-founding the activist think tank Focus on the Global South in Bangkok.

At this time, the new wave of globalization was piling up problems for the Philippines economy, with the government’s acceptance of Marcos’s debt of $26 billion, and its tariff reforms causing largescale deindustrialization. Bello worked with others to oppose the administration’s drive to commit the Philippines to the precepts of the World Trade Organisation and Agreement on Agriculture, which aimed to bring about greater foreign penetration of the country’s domestic market.

Financial liberalisation and privatisation of water energy accompanied these mis-steps. The overall result was that between 1990 and 2010, the Philippines’ rate of growth slumped to the second lowest in Southeast Asia and a third of its people lived below the poverty line. Bello did not just analyse these issues, he took part in direct action against the institutions, including at the mass protest at the 1999 meeting of the World Trade Organisation in Seattle, where he was beaten up by club-wielding police. The scale of the protest, however, made people aware of the ’dark side’ of globalization and checked its rapid advance.

A year later, Bello was caught up in the unprovoked police attacks on peaceful protesters in Genoa, in which carabinieri shot dead one activist. But as Focus on the Global South continued providing invaluable advice to developing country delegations at these events, the West began to pull back from using the WTO to spearhead trade liberalisation.

As an alternative to global neoliberalism, Bello proposed deglobalization: “refocusing the economy back on production for the domestic market rather than for export markets, resubordinating the market to society, reasserting cooperation over competition.”

After 9/11, Bello threw himself into activity in opposition to the West’s war on Iraq. He is scathing about its cheerleaders: “I found Tony Blair, the prime minister who led Britain to war, to be even more repugnant than Bush, Jr. The latter was, in many ways, a blockhead… Blair was a hypocrite and a liar, parading as a champion of freedom and democracy while knowing that Saddam Hussein possessed no weapons of mass destruction.”

In Congress

Bello was elected to the Philippines Congress in 2007 as a member of Akbayan, a broadly social-democratic party, but far from constraining his activism, he was able to use this platform to be more effective. He was active in getting the Reproductive Health Law, which legalised family planning, onto the statue book; yet, ten years on the Philippines remains, along with the Vatican, the only country in the world with no divorce law and abortion remains criminalised.

Bello writes that his most challenging, and frustrating, experience in Congress was heading up the Committee on Overseas Workers Affairs and dealing with the racket of Filipino recruitment agencies conniving with receiving country governments and employers to exploit millions of migrant labourers, with Philippine government officials often facilitating the exploitation. “The government and the Philippine elite bore a grave responsibility for this system of exploitation in a larger sense, in that labour export was a substitute—and a poor one—for promoting economic policies that could absorb the millions of Filipinos who saw no alternative but to work abroad.” On a Congressional mission to Saudi Arabia, he discovered that the rape and abuse of Filipina domestic workers were common.

In 2024, Amnesty International Philippines awarded Bello the title of “Most Distinguished Human Rights Defender”. In his acceptance speech, he said: “Neoliberal policies are now discredited. The Washington Consensus is in the junk heap… Those who have been responsible for destroying economies cannot be allowed to just walk away from the wreckage, just as that monster Duterte cannot be allowed to just get away with spilling the blood of 27,000 Filipinos… It is high time we seek justice for economic crimes. It is high time we cease honouring such criminals with Nobel Prizes in Economics but bring them instead to the ICC.”

Life lessons

Bello ends where he began, when looking at the counter-revolution in Chile, with an analysis of the global far right. It is driven by racism and anti-migrant sentiment, of course, but a central cause of its return is the decades of neoliberalism that preceded it, as Bello analysed in his 2019 book.

Summing up, Bello says that his politics has been defined by a search for truth and a desire to act. But it has also been informed by “good, old-fashioned ethics”. Furthermore, it is the “absence of a strong moral compass or its underdevelopment that has led to the self-inflicted tragedies of the left.”

And the lessons he has learned over a lifetime of activity? One, the struggle never stops. Two, one might wish for victory in the course of one’s lifetime, but it is psychologically less devastating to consider the possibility that it could well take longer. Three, just as defeat can be learned from, so victory may blind one to the flaws and seeds of destruction that the successful project inevitably contains. Finally, vision: “Programs for change and against empire and war will have limited traction unless they are attached to a larger vision that responds not only to ‘class interest’ but to our fundamental values as human beings.”
