BANGKOK, June 6 — Thailand’s aviation regulator has tightened rules on power banks on flights after a series of lithium-battery scares, more than two months after standards set by the International Civil Aviation Organisation (ICAO) took effect.

The move follows the January 2025 Air Busan fire in South Korea, where early investigations suggested a power bank may have been involved, as well as Thai-linked incidents on Thai AirAsia in January 2024 and Bangkok Airways in July 2025. 

The Civil Aviation Authority of Thailand said power banks must now be carried only in cabin baggage and are banned from checked luggage, The Bangkok Post reported this week.

It capped devices at 100 watt-hours, or 20,000 milliampere-hours, while power banks between 101Wh and 160Wh require airline approval.

Each passenger may carry no more than two lithium-battery power banks, and devices with unclear or missing capacity labels are not allowed on board.

Passengers are also barred from charging power banks or using them to charge phones or other devices during flights. 

Power banks must be kept within reach, such as in a seat pocket, under the seat in front or on the passenger, and cannot be stored in overhead lockers.

The safety logic is simple: a lithium battery fire in the hold is hard to detect, while a smoking battery in the cabin can be isolated, cooled and contained by trained crew.

The ICAO guidelines, set on March 27, limits passengers to two power banks each, besides barring them from recharging the devices during flights. 

That means Thailand took about 10 weeks, or 69 days, to turn the latest international safety practice into a local regulator rule.

But Thailand was not starting from zero, as Thai Airways had already announced similar power bank restrictions in early April based on ICAO requirements. 

Malaysia Airlines, Firefly and MASwings tightened power bank controls on April 1, 2025, requiring passengers to keep devices with them, barring overhead storage and banning the charging of power banks in flight. 

Malaysia-based budget carrier AirAsia also moved to require power banks to be kept in the cabin and within reach, while barring their in-flight use and charging. 

Malaysia had also put core lithium-battery flight limits into a regulator directive as far back as December 2015, showing that parts of Thailand’s new package reflect safety practice that has existed regionally for more than a decade. 

Singapore moved faster on the 2026 ICAO update, limiting passengers flying out of the island nation to two power banks from April 15.

Singapore Airlines and Scoot had already banned passengers from using or charging power banks in flight from April 1, 2025, after a series of battery-related cabin fire incidents. 

The common international baseline remains that power banks and spare lithium batteries should travel in the cabin, devices under 100Wh are generally allowed, 101Wh to 160Wh devices require airline approval, and higher-capacity units are banned from passenger baggage.

Thailand’s version is slightly stricter in practice because it states the standard limit as 20,000mAh, below the roughly 27,000mAh often treated as the 100Wh equivalent for typical 3.7-volt power banks.

For travellers, the message is blunt: bring no more than two clearly labelled power banks, keep them in hand luggage, do not put them overhead, do not use them in flight, and charge your phone before boarding.

Mangrove forests straddle the edge of land and sea along some tropical and subtropical coastlines. These trees and shrubs have distinctive tangles of roots that trap sediment and produce organic matter, forming dense soils and efficiently storing carbon. Though mangroves cover only 1% of Earth’s surface, they store a whopping 15% of global ocean carbon in their trapped soils.

Their location along coastlines means mangroves are at the mercy of changing sea levels and sediment availability. Rising sea levels can drown mangroves or push them landward. At the same time, sediment supplies, belowground root growth, and organic matter accumulation can help build up mangrove soils, allowing forests to keep pace with sea level rise. So over time, will mangroves keep locking carbon into their soils, or will they start losing it?

Iwantoro et al. created a new model that examines the links between coastal processes to investigate vegetation growth and carbon accumulation in mangrove forests.

The researchers modeled a simplified tidal embayment to explore how different rates of sea level rise and sediment supplies would affect the mangroves. In these experiments, they found that carbon accumulation can increase at specific locations as waters rise because the increased water can lead to more mangrove growth—a result that matches existing data. However, when looking at landscape scales, they found sea level rise generally reduces total carbon sequestration through mangrove loss and soil erosion. The results showed that rising sea levels can alter mangroves from carbon storage sinks to carbon emitters.

The findings demonstrate that local trends in carbon sequestration may not be representative of larger-scale outcomes in mangrove forests. The study shows that understanding coastal landscapes as an interconnected system is crucial to understanding how mangroves can respond to climate and human-induced pressures, the researchers say. However, new assessments and approaches are needed to better understand future mangrove vulnerabilities. (Earth’s Future, https://doi.org/10.1029/2025EF006984, 2026)

RIO DE JANEIRO, June 9 — Airlines expect to carry more passengers this year but earn only half as much profit as in 2025, as high fuel prices don’t appear to be fully deterring travel, according to projections published Sunday.

The International Air Transport Association (IATA) predicted its 370 member airlines, which account for 85 per cent of global air traffic, will carry 5.1 billion passengers this year.

That is up 2.4 per cent from 2025, when passenger traffic was estimated to have reached 4.98 billion. The four billion mark was surpassed in 2023.

Asked by reporters about the impact of the war in the Middle East compared to the Covid-19 pandemic in 2020-2021, IATA Director General Willie Walsh replied: “I don’t see this as a crisis.”

“You’re looking at an industry that is forecasting growth,” he said. “If you extract the impact of the Middle East, we’re looking at growth of 3.5 per cent.”

This growth, however, will be accompanied by profitability only half as strong as last year’s, while Middle Eastern airlines are expected to post losses.

“War-related disruptions in the Middle East and rising fuel costs have shifted the outlook for airlines to the worse,” Walsh said in a statement.

“Profits will shrink from US$45 billion (RM181.4 billion) in 2025 to US$23 billion this year. And margins will shrink from 4.2 per cent to 2.0 per cent,” he said, referring to the net margin.

According to IATA’s calculations, net profit is expected to be US$4.50 per passenger, half the 2025 figure.

“Under the circumstances, that shows resilience. But it won’t even buy you a hot dog at most of the Fifa World Cup venues and it does not leave much of a buffer should other costs or taxes start rising,” Walsh said in the statement.

‘Fuel price shock’ 

With fuel costs rising — and those increases being passed on in part through higher ticket prices — the revenue of IATA member airlines is expected to grow nine per cent this year, reaching US$1.165 trillion.

“Airlines are bearing the brunt of the fuel price shock. While air fares are rising, airlines are still absorbing part of the hike in their bottom lines,” the IATA said.

Profitability will vary across different regions of the world, according to the organization’s projections.

Middle Eastern airlines, which have traditionally had access to an abundant supply of fuel, are expected to face a difficult year, with net margins projected to turn negative.

For these airlines, including Emirates and Qatar Airways, “the immediate recovery path is likely to be driven more by pricing than by a rapid return of volumes,” the IATA said.

European airlines are expected to become the most profitable (3.1 per cent net margin), followed by those in North America (2.5 per cent) and Asia-Pacific (2.1 per cent).

Despite significant geopolitical uncertainty and the inability to predict the duration of the war, the IATA is not worried about demand. It noted that according to its calculations, the average airline ticket price had fallen 26 per cent over the past 10 years. — AFP 

KUALA LUMPUR, June 12 — Parti Bersama Malaysia (Bersama) today urged the Selangor government to withdraw newly approved guidelines governing non-Muslim houses of worship and restart consultations with religious groups and other stakeholders.

The party, led by former ministers Rafizi Ramli and Nik Nazmi Nik Ahmad, also expressed solidarity with Petaling Jaya MP Lee Chean Chung, who recently raised concerns over the guidelines.

“Several of the approved rules have raised concerns among Buddhists, Christians, Hindus, Sikhs and followers of other faiths,” Bersama said in a press statement.

The party said the guidelines, approved by the Selangor executive council last November, included restrictions on establishing non-Muslim houses of worship in commercial areas, limits on building heights, conditions restricting access to main roads, and a requirement of one house of worship for every 5,000 residents.

While the state government has said the guidelines have yet to be enforced, Bersama argued that they are already being used as a reference by local authorities responsible for approving and regulating applications.

“We believe such regulations should not be formulated solely through administrative processes based on recommendations from government departments that view the matter only from administrative and management perspectives,” it said.

Bersama said regulations involving houses of worship were highly sensitive and should be developed through broader public engagement rather than administrative decision-making alone.

The party also said local councillors should play a greater role in reflecting the needs of residents and allowing local considerations to shape decisions on places of worship.

“The Selangor government should return the matter to the Exco and first revoke the latest guidelines approved in November 2025, so that consultation and engagement with all relevant stakeholders can begin anew,” it said.

Bersama called for fresh consultations involving religious representatives, community leaders, NGOs and other stakeholders before any revised guidelines are tabled again for approval.

Coastal landscapes are constantly being reshaped by natural forces, and as climate change causes more frequent storms and sea level rise, that change will only intensify. Because these areas are densely populated with homes, tourist destinations, and industries, understanding how and where the coast will change is a pressing issue. However, reliable predictions that lead to actionable knowledge are rare.

Lentz et al. describe the state of knowledge regarding coastal evolution, highlight gaps in scientists’ understanding, and describe opportunities for integrating information from various models, data sources, and end users.

Current coastal evolution predictions are often focused on too specific a location and are therefore hard to generalize or analyze too large a region and therefore lack detail, the authors say. In addition, it’s challenging for researchers to link the effects of acute events, such as storms, with long-term trends like sea level rise.

Improving these simulations will likely require combining many different types of models, including physics-based numerical models, models based on empirical measurements, and statistical models that include machine learning. To fully understand potential changes, the authors note that it is also essential to consider both coastal processes and human actions.

The researchers recommend several ways to improve consistency and collaboration in the field of coastal change forecasting. First, standardizing approaches and outcomes would make it easier to produce national-scale predictions. Right now, the variety of tools used across different locations makes it difficult for scientists to compare results and communicate effectively. They also emphasize the need for using coordinated research approaches. Stronger transdisciplinary collaboration, accompanied by essential training and support, would also enable scientists to make better predictions, the researchers say.

Comparing predictions to real-world observations of coastal landscape change could also help untangle this multifaceted challenge. By studying how coastlines have already changed, researchers can validate models and choose those that are performing best. Such comparisons require datasets that adequately capture coastal landscape change across both time and space. Remote sensing data and the use of artificial intelligence (AI) for data processing may help provide these improved datasets, the researchers suggest.

Engaging end users during the project planning process is also helpful because only end users truly know what kind of information they need to adapt to landscape change. Knowing how to engage end users can be difficult for physical scientists, but various tools and specialized personnel exist who can help coordinate these interactions, the authors say.

A Malaysia Airlines flight burst a tyre on Monday after aborting take-off at Hong Kong International Airport due to “technical issues,” but no injuries were reported.

The Airport Authority (AA) said the tyre burst occurred at around 9.18am on Monday.

Malaysia Airlines Flight MH79, bound for Kuala Lumpur, aborted taking off from the airport’s South Runway due to “technical issues,” the AA said.

“During deceleration, a tyre burst, and the aircraft veered off the runway and came to a stop on the taxiway.”

Following established procedures, the authority said, it arranged for a tow truck to remove the aircraft from the taxiway. “No injuries were reported,” it added.

Malaysia Airlines confirmed that the plane “discontinued take-off following a tyre-related issue.”

“The aircraft was safely brought to a stop in accordance with standard operating procedures. All passengers and crew are safe,” the company told HKFP in an emailed reply.

Photos circulating on social media show the burst tyre and several fire engines standing by next to the aircraft. One photo posted to Facebook shows an airport personnel member checking the burst tyre.

MH79 was originally scheduled to depart at 8.45am and arrive in Kuala Lumpur at 12.45pm. Flight-tracking site Flightradar24 shows that MH79 did not take off and returned to the ramp at the airport.

Malaysia Airlines said it “deeply regrets” the incident and that it was working on rebooking passengers on alternative flights or carriers.

Following the incident, the airport’s South Runway was closed for a routine inspection, the AA said. “Meanwhile, other flights used the Centre Runway for take-off and airport operations were largely normal.”

The South Runway reopened shortly after 10am on Monday, the authority added.

One of the officials involved in the study commissioned by Biden's Democratic administration accused Trump's Republican administration of "sidelining" the research — an allegation the Trump administration denies.

With less than a month before the Alberta government hopes to present a pipeline proposal to Ottawa, the B.C. government says it's being left out of the discussions.

Not quite as glamourous as a secret bank account.

For most people doing long-haul domestic travel in Japan, the Shinkansen is their default method of getting from Point A to far-away Point B. However, sometimes it’s just as quick, if not quicker, to fly, especially if you’re starting at one end of the country and going all the way to the other.

In addition, while Shinkansen tickets are more or less constant in price, airfares fluctuate, so if you time your trip right, flying can be quicker and more economical than taking the train. Taking a plane starts to look like an even better option if you’re racking up frequent flyer miles…unless, that is, you’re a member of the yakuza, in which case trying to get frequent flyer miles can get you arrested.

On May 17, the Fukuoka Prefectural Police arrested Yuta Hirayama, a 42-year-old man from the town of Onojo, Fukuoka Prefecture. According to his arrest report, Hirayama has no officially designated job, but the police say he is a registered member of an organized crime syndicate that’s a subordinate group to the Kudo-kai, a Japanese mafia group based in Fukuoka.

Between June and November of 2023, Hirayama took nine domestic flights with a major Japanese airline, including flights between Fukuoka and Tokyo’s Haneda Airport to visit an acquaintance who was in prison in east Japan. In the process, he accrued 4,224 frequent flyer miles to an account registered in his name. However, the terms of service for the airline’s frequent flyer program includes a clause that members, by using the program, profess that they are not members of a criminal organization. Based on their assertion that Hirayama is a member of such a group, the police say that by using his account to accrue miles, he committed an act of fraud.

As we’ve discussed before, transactions and service contracts with no-yakuza clauses are common in Japan. It’s illegal, for example, for yakuza members to make mobile phone contracts or attend professional baseball games, as telecom providers and sports leagues don’t want to be associated with criminal organizations. Businesses are especially leery of having yakuza as members of loyalty programs that offer any sort of customer credit, since it could be construed as providing them with financial benefits. That’s why, for example, there are supermarket point programs with no-yakuza clauses, and with 4,224 miles within the frequent flyer program that Hirayama was a member of being exchangeable for 4,224 yen (US$27) in flight credit, the airline has a no-yakuza clause as well.

There is an additional wrinkle to this case, though, in that Hirayama had been a member of the frequent flyer program since 2013, but the airline only added its no-yakuza clause in 2022. As such, even if proven to be a member of a criminal organization, Hirayama’s initial entry into the program wasn’t fraudulent. However, the 2022 no-yakuza clause was ostensibly among the periodic terms of service updates that such programs require users to agree to when logging into their account, placing the legal responsibility on yakuza members to read through the new terms and withdraw from the program. So while many people simply scroll down to where they can click “OK” on such updates, if you’re a gangster, you really should read through them.

It’s unclear whether prosecutors will seek jail time for Hirayama, but if he is confirmed to be a yakuza member, his frequent flyer miles will be forfeited.
