Global experts will debate threats from artificial intelligence (AI) at a gathering in Paris on Thursday and Friday, ahead of a summit of world leaders on the fast-moving technology.

Thousands are expected for the event aiming to find common ground on a technology that has upset many business sectors in less than two years — as well as to keep France and Europe on the map as credible contenders in the AI race.

Paris’ ambitions also stretch to stoking citizens’ interest in real-world uses of AI, taking stock of global governance of the technology and promoting ethical, accessible and frugal options.

Scientists including Yann LeCun, AI chief for Facebook owner Meta, will discuss its impact on fields including work, health and sustainability from Thursday at the prestigious Polytechnique engineering school.

The Frenchman, one of the fathers of the current wave of AI, and 20 other high-profile researchers dined with Emmanuel Macron on Wednesday, the French president’s Elysee Palace office said.

Saturday and Sunday will see talks on AI’s impact on culture before heads of state and government from around 100 countries and global tech industry leaders gather on Monday and Tuesday.

– DeepSeek invited –

High-profile attendees will include US Vice President JD Vance, Chinese Vice Premier Zhang Guoqing, European Commission President Ursula von der Leyen and German Chancellor Olaf Scholz.

Indian Prime Minister Narendra Modi is co-hosting the summit as Macron seeks to involve the Global South in a technology battle that is for now largely playing out between the United States and China.

Macron’s office said he would also host United Arab Emirates leader Mohamed Bin Zayed al Nahyan, widely known as “MBZ”, on Thursday to discuss “our two countries’ common ambition on AI”.

From the business side, X and Tesla chief Elon Musk has yet to confirm attendance — as has Liang Wengfeng, founder of Chinese startup DeepSeek, which shocked the world with its frugal, high-performance R1 model last week.

American figures such as OpenAI’s Sam Altman and Anthropic’s Dario Amodei, as well as Arthur Mensch of French AI developer Mistral, will all join the gathering.

In science, Meta’s LeCun will be flanked by the likes of Demis Hassabis, the Nobel chemistry prize-winning head of Google’s DeepMind AI research lab, and Berkeley machine learning researcher Michael Jordan.

Three more Nobel winners — computer scientist Geoffrey Hinton, journalist Maria Ressa and economist Joseph Stiglitz — will join a conference hosted by the International Association for Safe and Ethical AI (IASEI), created only last year.

– French AI efforts –

France hopes that the conference can reinforce its leading European position in AI, having already drawn several labs from leading AI firms to Paris, including Google, Meta and OpenAI.

The Polytechnique school has been singled out to host the scientific conference as a symbol of French excellence in the field.

“This summit has to be a moment to position Paris as the global capital of AI,” digital minister Clara Chappaz told AFP journalists.

After a month in which DeepSeek’s emergence shocked even Silicon Valley titans and the United States announced a $500-billion AI investment scheme, France and Europe have a lot to prove in the coming days.

Paris plans to announce major investments running into the billions, including for new data centres on its territory.



AI starts to help India’s struggling farms

Much of India's vast agricultural economy remains deeply traditional, beset by problems made worse by extreme weather driven by climate change - Copyright AFP -

Each morning Indian farmer R Murali opens an app on his phone to check if his pomegranate trees need watering, fertiliser or are at risk from pests.

“It is a routine,” Murali, 51, told AFP at his farm in the southern state of Karnataka. “Like praying to God every day.”

Much of India’s vast agricultural economy — employing more than 45 percent of the workforce — remains deeply traditional, beset by problems made worse by extreme weather driven by climate change.

Murali is part of an increasing number of growers in the world’s most populous nation who have adopted artificial intelligence-powered tools, which he says helps him farm “more efficiently and effectively”.

“The app is the first thing I check as soon as I wake up,” said Murali, whose farm is planted with sensors providing constant updates on soil moisture, nutrient levels and farm-level weather forecasts.

He says the AI system developed by tech startup Fasal, which details when and how much water, fertiliser and pesticide is needed, has slashed costs by a fifth without reducing yields.

“What we have built is a technology that allows crops to talk to their farmers,” said Ananda Verma, a founder of Fasal, which serves around 12,000 farmers.

Verma, 35, who began developing the system in 2017 to understand soil moisture as a “do-it-yourself” project for his father’s farm, called it a tool “to make better decisions”.

– Costly –


But Fasal’s products cost between $57 and $287 to install.

That is a high price in a country where farmers’ average monthly income is $117, and where over 85 percent of farms are smaller than two hectares (five acres), according to government figures.

“We have the technology, but the availability of risk capital in India is limited,” said Verma.

New Delhi says it is determined to develop homegrown and low-cost AI, with Indian Prime Minister Narendra Modi to co-host an AI summit in France opening on Monday.

Agriculture, which accounts for roughly 15 percent of India’s economy, is one area ripe for its application. Farms are in dire need of investment and modernisation.

Water shortages, floods and increasingly erratic weather, as well as debt, have taken a heavy toll in an industry that employs roughly two-thirds of India’s 1.4 billion population.

India is already home to over 450 agritech startups with the sector’s projected valuation at $24 billion, according to a 2023 report by the government NITI Aayog think tank.

But the report also warned that a lack of digital literacy often resulted in the poor adoption of agritech solutions.

– Buzzing –

Among those companies is Niqo Robotics, which has developed a system using AI cameras attached to focused chemical spraying machines.

Tractor-fitted sprays assess each plant to provide the ideal amount of chemicals, reducing input costs and limiting environmental damage, it says.

Niqo claims its users in Maharashtra and Andhra Pradesh states have cut their outlay on chemicals by up to 90 percent.

At another startup, BeePrecise, Rishina Kuruvilla is part of team that has developed AI monitors measuring the health of beehives.

That includes moisture, temperature and even the sound of bees — a way to track the queen bee’s activities.

Kuruvilla said the tool helped beekeepers harvest honey that is “a little more organic and better for consumption”.

– State help –


But while AI tech is blossoming, takeup among farmers is slow because many cannot afford it.

Agricultural economist RS Deshpande, a visiting professor at Bengaluru’s Institute for Social and Economic Change, says the government must meet the cost.

Many farmers “are surviving” only because they eat what they grow, he said.

“Since they own a farm, they take the farm produce home,” he said. “If the government is ready, India is ready.”



Trump’s Gaza plan derails Saudi-Israel ties: analysts

US President Donald Trump’s plan to take over Gaza will imperil attempts to forge landmark ties between Saudi Arabia and Israel and fuel anti-American sentiment in the oil-rich kingdom, analysts said.

Trump’s proposal to redevelop Gaza and oust the more than two million Palestinians living in the territory prompted a global backlash and enraged the Arab world, making it difficult for the Saudis to consider normalisation.

“If this is going to be his policy, he shut the door on Saudi recognition of Israel,” James Dorsey, researcher at the Middle East Institute of the National University of Singapore, told AFP.

Recognition of Israel by Saudi Arabia, home to Islam’s holiest sites, is seen as a grand prize of Middle East diplomacy intended to calm chronic tensions in the region.

But Saudi Arabia, the world’s biggest oil exporter and the Middle East’s largest economy, now faces the spectre of instability on its borders if neighbouring Jordan and Egypt suddenly house large numbers of Gaza exiles.

At the same time, Riyadh must maintain cordial relations with Washington, its long-time security guarantor and bulwark against key regional player Iran.

“When it comes to security, Saudi Arabia has nowhere to go but to Washington,” Dorsey said. “There’s nobody else. It’s not China. They’re not willing and they’re not able.

“And post-Ukraine, do you want to rely on Russia?”



– Quick reaction –



The Saudis were engaged in tentative talks on normalisation via the United States until the outbreak of the Gaza war, when they paused the negotiations and hardened their position.

They reacted with unusual speed to Trump’s proposal, made during an appearance with Israeli Prime Minister Benjamin Netanyahu in Washington.

About an hour after his comments, at around 4:00 am Saudi time, the foreign ministry posted a statement on X that “reaffirms its unequivocal rejection of… attempts to displace the Palestinian people from their land”.

In the same statement, the Saudis rejected Netanyahu’s comment that normalisation was “going to happen”, repeating their insistence there would be no ties without a Palestinian state.

Trump’s plan carries real risks for Riyadh, which is throwing everything at an ambitious post-oil economic makeover that relies on stability to attract business and tourism.

If Gazans are displaced to Egypt and Jordan, it “will weaken two countries essential to regional stability and particularly to Saudi security”, said Saudi researcher Aziz Alghashian.

“Trump’s plan, coupled with Netanyahu’s approach, poses major risks for Saudi Arabia.

“It highlights that they are not true partners for peace in Riyadh’s eyes — especially Netanyahu, who appears to want all the benefits without making concessions.”

– ‘Making normalisation harder’ –


Trump’s declarations “will further destabilise the region and fuel anti-American sentiment, particularly in Saudi Arabia”, said Anna Jacobs, of the International Crisis Group think tank.

“He is making Saudi-Israel normalisation harder, not easier.”

Andreas Krieg of King’s College London said Saudi Arabia would not agree meekly to normalisation if ordered by Washington.

Prior to the Gaza war, the Saudis were negotiating for security guarantees and help building a civilian nuclear programme in return for Israeli ties.

“They are not a US vassal state and so they’re not just taking a diktat from Trump,” said Andreas Krieg of King’s College London.

“And I think it will stand firm on their positions, willing to negotiate here and there. But the principal red lines remain.

“Nobody in Saudi Arabia has an interest in selling out Palestinian statehood. That is the last and the most important bargaining chip that the Saudis have in terms of authority and legitimacy in the Arab and Muslim world.”

But the question is how Saudi Arabia and its 39-year-old de facto ruler, Crown Prince Mohammed bin Salman, will proceed.

“I don’t think that the Saudis will take any major steps now,” said Krieg.

“They obviously have their own levers that they can use for pressure on America, particularly in the energy sector. I don’t think the Saudis will want to use it at this point.”

‘Social Network’ star Eisenberg slams Zuckerberg as ‘obsessed with power’

Adam PLOWRIGHT

Hollywood star Jesse Eisenberg, who played Mark Zuckerberg in 2010 hit “The Social Network”, told AFP the Facebook owner had evolved from having “a sense of righteousness” into “somebody obsessed with power”.

Eisenberg took a broadly sympathetic view of the Silicon Valley billionaire when playing him in the David Fincher-directed movie, which helped shape Facebook’s public image.

“As an actor, your job is to empathise with the character, not only empathise, but justify,” Eisenberg told AFP in an interview to promote his widely acclaimed new movie “A Real Pain”.

“I was thinking of the (Zuckerberg) character as somebody who was able to understand certain things so much quicker than other people, and who had a kind of sense of righteousness that was born out of his own brilliance,” he explained.

But 15 years later, with Zuckerberg shifting his political views to align with Donald Trump’s new administration and cutting fact-checking on the US platform, Eisenberg has revised his opinions.

“You kind of wonder like ‘oh, so this person didn’t evolve into a profile in courage’. This person evolved into somebody obsessed with avarice and power and so that’s kind of interesting for me as an actor who at one point thought about this person a lot,” the 41-year-old New Yorker added.

“The Social Network” brought Eisenberg worldwide fame and an Oscar nomination for best actor.

He is set to return to the Academy Awards on March 2 with “A Real Pain”, which he wrote, directed and acted in alongside “Succession” star Kieran Culkin.

The unlikely comedy about two Jewish cousins who go on a Holocaust tour in Poland picked up two Oscar nominations: Eisenberg for best original screenplay, and Culkin for best supporting actor.

– ‘The depths’ –


The film has won rave reviews since it was first shown at last year’s Sundance Film Festival and has been released widely in American and European cinemas over the last three months.

Many critics have noted the deft dialogue between Eisenberg and Culkin’s characters — David and Benji — with their humour and mental health struggles bringing new twists to two classic Hollywood formats, Holocaust and road movies.

For Eisenberg, the script and setting were intensely personal, returning to the land of his Polish grandparents who fled the Nazis and drawing on his experience of obsessive-compulsive disorder (OCD) and anxiety.

“David’s life is very similar to my life… the pills that David takes are the pills that I take to the point where the prop department asked me if they can borrow my pills,” he explained.

“But I’ve also been Benji. I’ve been to the depths that Benji has been to emotionally,” he added.

The core of the film reflects Eisenberg’s contemplation of existential guilt.

“How is it possible that I have self-pity, or that I spend an hour every morning trying to get out of bed when my grandparents’ generation were two inches away from being slaughtered?” said Eisenberg, who applied for and gained Polish nationality after filming.

“How is it possible that all of us don’t wake up every morning and kiss the ground that we’re alive?”

– ‘Great timing’ –

Culkin was cast in the film despite not being Jewish, something Eisenberg said he was initially “hesitant” about.

“Once we relieved ourselves of that very specific consideration, he seemed like far and away the only person that could do the part,” he explained.

Culkin brought his “unusual energy” and “great sense of timing and intelligence” to filming, which also saw him repeatedly reject instructions from his co-lead and director, who was nominally in charge of the shoot.

“I was directing the movie, sure, but Kieran was leading the day. I would set up a shot, and Kieran would make fun of me and say that the shot was stupid,” said Eisenberg.

The married father-of-one says he sees himself carrying on in front of and behind the camera, with “A Real Pain” a follow up to 2022’s “When You Finish Saving the World”, which he also directed.

But nothing in the movie business compares to the satisfaction he felt doing volunteer work during the Covid pandemic, however.

“I was volunteering every day at this domestic violence shelter that was run by my mother-in-law. And I had never been happier in my life,” he said.





Variable outcomes: Contrasting patterns form US states over women’s health outcomes

With over 168 million women in the U.S., and over one-third of them skipping necessary medical care because of the cost, the non-profit organization SmileHub has released new reports on the Best States for Women’s Health in 2025 and the Best Charities for Health & Wellness.

To highlight the best states for women’s health and the ones that need to improve the most, SmileHub compared each of the 50 states based on 18 key metrics.

The data set ranged from the maternal mortality rate to the quality of women’s hospitals to the affordability of a doctor’s visit. Three key health dimensions were deployed for the assessment: 1) Health & Living Standards, 2) Health Care Policies & Support Systems and 3) Safety Risk.

The top ten ‘Best States for Women’s Health’ were found to be:Massachusetts
Hawaii
Connecticut
New York
New Jersey
Maryland
California
Minnesota
Vermont
New Hampshire

In contrast, tipping to the other end of the scale, the top ten ‘States in Need of Improvement’ were established as:Georgia
Louisiana
West Virginia
Tennessee
Alabama
Texas
Mississippi
Nevada
Arkansas
Oklahoma

Delving beyond the headline rankings, the data revealed that Massachusetts has the lowest uninsured rate among women – 7.9 times lower than in Texas, which has the highest rate. Health insurance is important in the U.S. for increasing life chances.

One of the biggest poor health issues is smoking (cigarettes or vaping). Utah has the lowest female smoker rate – 4.3 times lower than in West Virginia, which has the highest rate

A very different measures is the maternal mortality rate (the number of women who die from pregnancy-related causes while pregnant or within 42 days of pregnancy termination). Here, California has the lowest maternal mortality rate – 4.4 times lower than in Alabama, which has the highest rate.

Radon risk: Why Virginians need to take stock

The U.S. National Cancer Institute lists radon as the second-leading cause of lung cancer behind cigarette smoking. Patterns of radon risk vary across the U.S. Much of Southwest Virginia is at high risk for this colorless, odorless gas.

Radon is produced from the natural radioactive decay of uranium, which is found in all rocks and soils. Radon can also be found in water.

“We know enough about the risks and have affordable ways to test and mitigate radon that our efforts should be focused on raising awareness and preventing exposure,” Philip Agee, an assistant professor of building construction at Virginia Tech states.

Citing the U.S. National Institutes of Health estimate that 15,000 to 22,000 deaths in the country each year are radon-related, Agee has urged Virginias who have never had their home tested to be proactive.

“Consumers can buy short-term tests at hardware stores for about $15,” Agee remarks. “Long-term Internet-enabled monitoring solutions run between $100 to $200.”

Radon is found in soil and enters homes via cracks in building foundations, basements, crawlspaces, and other indoor places where air leaks out. This lowers the air pressure indoors and allows the higher-pressure gas from the soil to infiltrate.

The U.S. Environmental Protection Agency maintains a map of radon risks for each county/city in the U.S. Unlike other states in the highest risk zones, Virginia does not require radon tests during real estate transactions.

“Homebuyers can have radon tests completed with the home inspection process for a fee,” Agee adds, estimating a cost of about $100 to $200 for a professional service.

Agee’s research has also found that weather can have an impact too. “Radon concentrations will increase in homes following heavy rainfall, and then concentrations decrease over 24 to 48 hours after the rain stops. ” Agee attributes this to more moisture in the soil, preventing radon from escaping to ambient conditions and instead finding a “path of least resistance” into buildings.

“We spend approximately 90 percent of our lives inside the built environment, so your indoor environment impacts your long-term health. If testing shows radon above acceptable levels, radon mitigation systems are used to reduce the risk of radon entering the home,” Agee concludes.
Judge pauses Musk plan for mass US govt cull

A judge paused a scheme masterminded by billionaire Elon Musk to slash the US government by encouraging federal workers to quit through a mass buyout by midnight Thursday.

The federal judge in Massachusetts ordered a temporary injunction on the deadline given by Musk for the country’s more than two million government employees to quit with eight months’ pay or risk being fired.

The deadline is now extended to Monday when US District Judge George O’Toole will hold a hearing on the merits of the case brought by labor unions, US media reported.

Musk, the world’s richest person and President Donald Trump’s biggest donor, is in charge of a free-ranging Department of Government Efficiency (DOGE) that aims to radically downsize federal agencies.

According to White House Press Secretary Karoline Leavitt, more than 40,000 staff have so far accepted the buyout deal — a relatively small number.

Unions representing some 800,000 civil servants and Democratic members of Congress are resisting the scheme and have challenged the legality of threats to fire civil servants.

But the campaign — fanned by anti-government-worker invective from Trump and his aides — has already severely disrupted the huge departments and agencies that for decades have run everything from education to national intelligence.

USAID, the government’s agency for distributing aid around the world, has been crippled, with foreign-based staff ordered home and the organization’s programs lambasted daily as wasteful by the White House and right-wing media.

Trump has also repeatedly said he wants to shut down the Department of Education. The inducements to resign have even been extended to the CIA.

In another sign of the scale of the intended cuts, an official with the agency that manages government property said the real estate portfolio, barring Department of Defense buildings, should be cut by “at least 50 percent.”

Leavitt defended the onslaught, telling reporters that federal workers should “accept the very generous offer.”

She said “competent” replacements would be found for those who “want to rip the American people off.”

Among the controversies swirling around the Musk plan is how much access the South African-born tycoon is getting to secret government data, including the Treasury’s entire payment system.

Treasury Secretary Scott Bessent told Bloomberg TV on Thursday that there was “a lot of misinformation” and that access to such data was only given to two Treasury employees who are working with Musk.

Bessent said those employees had “read-only” access, meaning they couldn’t change the data.

– ‘Chill’ or big ‘con’? –

Workers considering the buyout offer face considerable uncertainty, including over whether Trump has the legal right to make the offer and whether the conditions will be honored.

The plan was first announced in an email sent across most of the vast government and titled “Fork in the road” — the same as one Musk sent to all employees at Twitter when he bought the social media platform in 2022 and renamed it X.

Musk says the paid departures are a chance to “take the vacation you always wanted, or just watch movies and chill, while receiving your full government pay and benefits.”

Unions warn that without Congress signing off on the use of federally budgeted money, the agreements may be worthless.

“Federal employees shouldn’t be misled by slick talk from unelected billionaires and their lackeys,” Everett Kelley, president of the large American Federation of Government Employees (AFGE).

“This deferred resignation scheme is unfunded, unlawful and comes with no guarantees. We won’t stand by and let our members become the victims of this con.”

The Massachusetts lawsuit also casts doubt on assertions that workers would be free to look for other jobs during their deferment periods, citing ethics regulations.

An employee in the US Office of Personnel Management, where Musk has put his own staff in key positions, said the plan was to encourage resignations through “panic.”

“We’re trying to instill a panic so that people just walk out the door and leave government in a crippled state, which is partly their objective,” the employee told AFP, speaking on condition of anonymity.

When catastrophic rainfall began in early June 2024 in southern China (S. China)—an event that caught worldwide attention due to its devastating consequences—no plausible explanation had yet been proposed. This research was inspired by the finding of the international project “Global Energy and Water Cycle Exchanges/Impact of Initialized Land Surface Temperature and Snowpack on Subseasonal-to-Seasonal Prediction” (GEWEX/LS4P), which identified a lagged relationship between spring land temperatures over the Tibetan Plateau (TP) and downstream summer precipitation over East Asia. Specifically, the findings indicated that when the TP experienced a warm/cold spring, southern China (S. China) was likely to experience a wet/dry summer, respectively.

By examining the record-breaking warm spring land temperatures over the TP in 2024—the warmest TP spring since 1980—the researchers conjectured that this extreme TP warming and the subsequent heavy rainfall in S. China were consistent with the LS4P hypothesis. This study was initiated during the 2024 GEWEX Open Science Conference (July 7-12) in Japan. A group of scientists participating in the LS4P project, including experts from UCLA, the Institute of Atmospheric Physics, Chinese Academy of Sciences (IAP/CAS), the Chinese Meteorological Administration (CMA), the Earth System Science Interdisciplinary Center (ESSIC) at the University of Maryland, College Park, and other institutions, voluntarily collaborated in response to an initiative by LS4P Co-Chair Professor. Yongkang Xue of UCLA. Their goal was to provide a timely explanation for the scientific and public communities.

The ESM developed by the National Center for Environmental Research (NCEP) and UCLA was used for this study. Since the study was conducted in close to real-time during an ongoing event, Mr. Ratko Vasic of NCEP provided valuable assistance in obtaining initial conditions for model simulations. Drs. Qian Li and Xianghui Kong of the IAP, Chinese Academy of Sciences, promptly produced all numerical experiment results and conducted preliminary analyses.

One of the most challenging aspects of this study was reproducing the observed extreme warm temperatures over the TP in the ESM. Initially, the ESM failed to reproduce the homogeneous extreme warm May temperatures over the TP and underestimated the heavy June rainfall in S. China, exhibiting a severe dry bias. After improving the land temperature initialization for the TP, the ESM successfully reproduced most of the observed TP May 2-meter temperature (T-2m) anomalies and simulated approximately 55% of the observed extraordinary June rainfall anomaly in S. China. The results passed a more stringent field significance test, indicating these results did not occur by chance.

Additionally, the experiment realistically simulated other observed anomalies, including the heavy rainfall in Bangladesh, where an extraordinary June flood occurred and was widely reported in the media, as well as abnormally wet conditions over the eastern TP and southern Japan, and dry conditions over northern China.

The study also assessed the influence of sea surface temperature (SST), traditionally used in climate and weather predictions. Results showed that May and June 2024 global SSTs, with only moderate anomalies, contributed about 17% of the observed rainfall anomaly.

  Subseasonal-to-seasonal (S2S) precipitation prediction for late spring and summer, which involves a substantial number of extreme hydroclimate events, has remained stubbornly low in accuracy for years. To tackle this persistent challenge, the World Meteorological Organization (WMO) launched a joint S2S Prediction Project, aimed at improving predictions ranging from 2 weeks to 3 months. Among various factors, land initialization and configuration have been identified as one of key areas with the potential to significantly enhance S2S predictions. While many land variables, such as albedo, soil moisture, snowpack, and vegetation, have been utilized for climate and weather predictions since the 1970s, the memory effect of land temperature on predictions has been largely underappreciated until the inception of LS4P. This is surprising given that the T-2m measurements have the highest quality among land variables, with the longest meteorological observational records, global coverage, and dense measurement networks.

The LS4P group, comprising many of the world’s leading climate and weather prediction and research centers, has made great strides in demonstrating the critical role of high mountain land temperature anomalies in S2S predictions. They have published many peer-reviewed papers within the field. “This represents a significant contribution of GEWEX to the S2S prediction that is scientifically challenging and highly relevant to society,” emphasized Professor Xubin Zeng, Co-Chair of the GEWEX. Dr. Aaron Boone of Meteo France asserts this work opens new avenues for improving S2S prediction for operational applications, which is increasingly important given the rising frequency of anomalous meteorological events observed worldwide.

Despite its promise, this approach has yet to gain full recognition within the broader scientific community, where traditional SST-based methods continue to dominate. Historically, it has often taken years to identify the causes of climate-related catastrophic events. The new and exciting results from this study, completed in such a short timeframe, underscore the robustness of this innovative approach. This study demonstrates that excessive TP spring land heating was the primary factor driving the catastrophic June 2024 rainfall in S. China. Yongkang acknowledged that, while there remain many unresolved challenges with this approach, the team hopes their paper in Science Bulletin will inspire further research using diverse methodologies to advance S2S prediction of extreme hydroclimate events and increase public awareness of the latest advancements in this field made by LS4P scientists.


 

New research highlights the governance and ecological challenges of mangroves in the Andaman and Nicobar islands




Vrije Universiteit Brussel






Dr. Poti’s research highlights the impact of the 2004 Sumatra-Andaman earthquake and tsunami on mangrove ecosystems in these islands. The tsunami led to significant land subsidence (up to 3 m) and uplift (up to 1.4 m), dramatically altering the tidal patterns crucial for mangrove survival. As a result, 97% of mangroves in the Nicobar Islands were lost. However, these changes also opened up new intertidal zones, allowing for mangrove colonization in previously non-mangrove terrestrial areas.

“A key finding of my research is the inadequate policy response to these ecological changes.” Dr. Poti says. “Despite the crucial role mangroves play in coastal protection and fisheries, the governance framework remains fragmented, with limited coordination between the Fisheries and Forest Departments. Additionally, top-down governance often overlooks local ecological conditions, leading to failed mangrove restoration efforts.” ​

Encouragingly, Dr. Poti notes an emerging trend of informal collaboration between government officers and researchers, which has the potential to improve conservation efforts. While challenges remain, this shift indicates a growing recognition of the importance of scientific input in environmental policy.

This study is led by Dr. Guanghui Yu from School of Earth System Science, Tianjin University. This study delves into the role of fungal biomass on the formation of soil stable carbon, conducted by Xiang Wang and Guanghui Yu. Fungi play a crucial role in ecosystem processes such as soil carbon cycling, decomposition, nutrient turnover, and symbiosis with plants. Most vascular plants form mycorrhizae, where fungi exchange carbon for nutrients like phosphorus and nitrogen. Fungal hyphae can extend over vast areas, influencing the "hyphosphere", a zone larger and more dynamic than the rhizosphere. When fungi die, their hyphal fragments contribute to microbial residues, or "necromass", which are key to forming mineral-associated organic matter (MAOM). Fungal necromass is significant in soil organic matter, especially in topsoil, and is sensitive to climate change and management. Despite the importance of fungi in carbon cycles, their role in stabilizing carbon over long timescales is not fully understood.

This study explores the role of fungal biomass in carbon persistence across biomes. The researchers hypothesize that hypha-mineral interactions help stabilize carbon. They analyzed fungal biomass and mineral-associated carbon in six biomes and used nanoscale imaging to study hypha-mineral interactions in Pinus silvestris rhizospheres. Findings show fungi’s vital role in stabilizing carbon in soils, with implications for global carbon cycling.

The researchers collected data on microbial biomass carbon stocks and reactive mineral-associated carbon stocks from six different ecosystems to better understand the critical role of microbial biomass in forming stable soil carbon pools at the ecosystem level. The results revealed a strong correlation between microbial biomass carbon and reactive mineral-associated carbon, indicating their significant contribution to the persistence and stability of soil carbon. The topsoil microbial biomass carbon accounted for 86% of the total microbial biomass carbon, showing a clear connection to the entire soil profile’s microbial carbon stock. Interestingly, fungal biomass carbon in the topsoil was strongly correlated with the reactive mineral-associated carbon across the whole soil profile, while bacterial biomass carbon showed a weaker correlation.

To investigate the hypha-mineral interactions and uncover the key mechanisms behind the persistence of fungal biomass carbon, the researchers used high-resolution nanoscale secondary ion mass spectrometry (50 nm resolution) to analyze mycorrhizae in the pine rhizosphere soil. The results revealed that hyphae were surrounded by a distinct mineral coating layer, approximately 500–600 nm thick. This mineral coating, closely associated with carbon, provided direct evidence that mineral nanoparticles help protect fungal exudates.

The study proposes a new conceptual model to explain these interactions, emphasizing the multifaceted roles fungi play in soil organic carbon persistence. According to the model, living fungi contribute to the soil biogeochemical carbon cycle in two ways: First, hypha-mineral interactions generate reactive oxygen species that accelerate organic matter decomposition, enhancing nutrient cycling. Second, the nanoparticles produced by fungi facilitate the formation of organo-mineral complexes, which stabilize soil organic carbon. After death, fungal necromass interacts with nanoparticles, further stabilizing the carbon.

The findings of this study bring together ecosystem-level processes and microscopic

In a groundbreaking discovery, researchers from Nagoya University in Japan and the Slovak Academy of Sciences have unveiled new insights into the interplay between quantum theory and thermodynamics. The team demonstrated that while quantum theory does not inherently forbid violations of the second law of thermodynamics, quantum processes may be implemented without actually breaching the law. This discovery, published in npj Quantum Information, highlights a harmonious coexistence between the two fields, despite their logical independence. Their findings open up new avenues for understanding the thermodynamic boundaries of quantum technologies, such as quantum computing and nanoscale engines.

This breakthrough contributes to the long-standing exploration of the second law of thermodynamics, a principle often regarded as one of the most profound and enigmatic in physics. The second law asserts that entropy—a measure of disorder in a system—never decreases spontaneously. It also states that a cyclically operating engine cannot produce mechanical work by extracting heat from a single thermal environment and underscores the concept of a unidirectional flow of time.

Despite its foundational role, the second law remains one of the most debated and misunderstood principles in science. Central to this debate is the paradox of “Maxwell's Demon,” a thought experiment proposed by physicist James Clerk Maxwell in 1867.

Maxwell envisioned a hypothetical being—the demon—capable of sorting fast and slow molecules within a gas at thermal equilibrium without expending energy. By separating these molecules into distinct regions, the demon could create a temperature difference. As the system returns to equilibrium, mechanical work is extracted, seemingly defying the second law of thermodynamics.

The paradox has intrigued physicists for over a century, raising questions about the law’s universality and whether it depends on the observer’s knowledge and capabilities. Solutions to the paradox have largely centered on treating the demon as a physical system subject to thermodynamic laws. A proposed solution is erasing the demon’s memory, which would require an expenditure of mechanical work, effectively offsetting the violation of the second law.

To explore this phenomenon further, the researchers developed a mathematical model for a “demonic engine,” a system powered by Maxwell’s demon. Their approach is rooted in the theory of quantum instruments, a framework introduced in the 1970s and 1980s to describe the most general forms of quantum measurement.

The model involves three steps: the demon measures a target system, then extracts work from it by coupling it to a thermal environment, and finally erases its memory by interacting with the same environment.

Using this framework, the team derived precise equations for the work expended by the demon and the work it extracts, expressed in terms of quantum information measures such as von Neumann entropy and Groenewold-Ozawa information gain. When comparing these equations, they got a surprising result.

“Our results showed that under certain conditions permitted by quantum theory, even after accounting for all costs, the work extracted can exceed the work expended, seemingly violating the second law of thermodynamics,” explained Shintaro Minagawa, a lead researcher on the project. “This revelation was as exciting as it was unexpected, challenging the assumption that quantum theory is inherently ‘demon-proof.’ There are hidden corners in the framework where Maxwell’s Demon could still work its magic.”

Despite these loopholes, the researchers emphasize that they don't pose a threat to the second law. “Our work demonstrates that, despite these theoretical vulnerabilities, it is possible to design any quantum process so that it complies with the second law,” said Hamed Mohammady. “In other words, quantum theory could potentially break the second law of thermodynamics, but it doesn't actually have to. This establishes a remarkable harmony between quantum mechanics and thermodynamics: they remain independent but never fundamentally at odds.”

This discovery also suggests that the second law does not impose strict limitations on quantum measurements. Any process permitted by quantum theory can be implemented without violating thermodynamic principles. By refining our understanding of this interplay, the researchers aim to unlock new possibilities for quantum technologies while upholding the timeless principles of thermodynamics.

“One thing we show in this paper is that quantum theory is really logically independent of the second law of thermodynamics. That is, it can violate the law simply because it does not ‘know’ about it at all,” Francesco Buscemi explained. “And yet—and this is just as remarkable—any quantum process can be realized without violating the second law of thermodynamics. This can be done by adding more systems until the thermodynamic balance is restored.” The implications of this study extend beyond theoretical physics. Illuminating the thermodynamic limits of quantum systems provides a foundation for innovations in quantum computing and nanoscale engines. As we explore the quantum realm, this research serves as a reminder of the delicate balance between the fundamental laws of nature and the potential for groundbreaking technological advancements.
