Readers urge broader debate on UK food resilience

Radio galaxies are powered by active galactic nuclei, bright central regions associated with matter falling toward supermassive black holes. Some produce jets that feed enormous radio-emitting lobes. When the jets stop, the lobes remain visible for a time as their particles lose energy. Astronomers call these systems remnant radio galaxies.

Researchers led by Sushant Dutta of the University of Cape Town and the Inter-University Institute for Data Intensive Astronomy studied 14 candidate remnants in the XMM-Newton Large-Scale Structure field.

They combined observations from the MeerKAT MIGHTEE and uGMRT superMIGHTEE surveys with data from LOFAR, GMRT and the Karl G. Jansky Very Large Array. Together, the observations covered radio frequencies from 144 MHz to 1.5 GHz.

Models of the sources' radio spectra classified 12 as remnants and reclassified two as active. The result shows why observations at several frequencies are important: candidates selected from limited data can be misidentified.

The models estimated total spectral ages of about 8 million to 42 million years, with a median of roughly 12 million years. These estimates are shorter than those for many remnants examined in earlier studies. The fraction of each source's estimated lifetime spent in the remnant stage ranged from 4% to 83%, suggesting that the sample includes galaxies at very different stages after their jets switched off.

Most of the sources are at relatively high redshifts. The researchers found an association between higher redshift and younger estimated spectral age after accounting for radio luminosity. They said stronger energy losses involving the cosmic microwave background, along with rapid expansion in low-density environments, could help explain the pattern. The observational study does not establish either explanation as the sole cause.

The sample is small, and the ages depend on models of how particles and magnetic fields evolve in the radio lobes. Even so, the findings point to a faint population that previous surveys may have missed. Future surveys with the Square Kilometre Array should find many more such sources and test how common short-lived remnants are.

The study was published in Monthly Notices of the Royal Astronomical Society.

The Met Office forecast a shift to cooler, more unsettled weather after a heatwave. Some places could receive intense showers, while others may get little rain. Water running quickly from hard, very dry ground can add to local flood risk when rainfall is particularly heavy.

That does not mean the drought is ending. At the start of August, Environment Agency figures showed that seven areas of England were in drought. Reservoir storage across England had fallen to 69%, which was 11.6 percentage points below the long-term average for that time of year. Five monitored reservoirs were classed as exceptionally low.

The dry conditions were also affecting rivers, wildlife and farming. The agency reported low flows, algal blooms, fish deaths and restrictions on water abstraction. More than 25 million people were covered by temporary limits on water use in early August.

Water supply problems continued in south-east England. South East Water said thousands of customers in parts of Kent lost supplies before most connections were restored. The company asked customers to limit use while storage tanks recovered.

Wessex Water also announced a temporary-use ban covering about 1.4 million customers in parts of south-west England. It was the company's first such restriction since 1976. Thames Water, which had already imposed restrictions, asked customers to keep reducing demand.

Brief downpours can reduce immediate pressure on vegetation and lower wildfire risk, but drought recovery normally requires sustained rainfall. Rivers, reservoirs and groundwater respond over different timescales, so several wet days in one area cannot restore depleted water resources across England.

Flooding and drought can therefore occur at the same time in different places, or even in the same region. A short, intense storm can overwhelm drains and produce rapid runoff while longer-term river flows, groundwater and reservoirs remain unusually low.

he National Anti-Corruption Bureau of Ukraine said investigators had identified a group suspected of laundering 150 million hryvnias, about $3.4 million, to provide bail for a defendant in a major corruption case from 2025.

The agency said the suspects included a former lawmaker, the chair of a state bank's board, the head of its supervisory board and a deputy head of the presidential office. Investigators released few other details.

President Volodymyr Zelenskyy dismissed Iryna Mudra as a deputy head of the presidential office on the same day. Her office was searched, according to lawmaker Oleksii Honcharenko, but investigators had not publicly named Mudra as a suspect in the information reported by the Associated Press. Zelenskyy was not implicated in the case.

The investigation added to political pressure on the government a day after former defence minister Mykhailo Fedorov called for a way to hold national elections during the war.

Fedorov said Ukraine should find a legal, safe and realistic mechanism to restore a full democratic process if the war continues. Ukraine is under martial law, which currently prevents national elections. His statement was therefore a political proposal, not an announcement that a vote had been scheduled.

Zelenskyy dismissed Fedorov in July during a disputed military leadership reshuffle. The decision prompted street protests from supporters of the former minister. Khmara then served as acting defence minister before lawmakers confirmed him in the post on August 19.

In South Korea, a landslide struck the ground floor of an apartment building in Geoje, South Gyeongsang province. One resident was taken to hospital in cardiac arrest and later pronounced dead. Two people were injured in Geoje and two others in nearby cities, according to the Interior and Safety Ministry.

Geoje recorded 805.7 millimetres of rain from Saturday through 8 a.m. on Monday, while nearby Tongyeong received 671.9 millimetres over the same period. Rain continued after those measurements, pushing later totals higher.

About 390 people were evacuated in southern South Korea, and roughly 3,580 homes lost power. Prime Minister Han Seong-sook instructed emergency services and local authorities to focus on rescuing stranded residents and protecting people in high-risk areas.

The flooding in the Philippines was a separate emergency. Seasonal monsoon rain, intensified earlier by a tropical storm, flooded roads in metropolitan Manila and provinces on the main island of Luzon. The government suspended work in public offices and cancelled in-person classes in affected areas, with schools asked to move lessons online where possible.

The Philippine Office of Civil Defense said about three weeks of intermittent monsoon rain and the earlier storm had affected around 5 million people. At least 23 deaths were reported, mostly from floods and landslides, and nearly 25,000 people remained in government shelters on August 17.

Ten of the deaths occurred in Baguio, where a landslide buried three houses on August 9. Rescuers pulled three injured people alive from the mud, rocks and debris.

The casualty and displacement figures were preliminary and may change as authorities assess damage and continue recovery work.

Researchers David Wolf and Kenji Takeuchi used post-storm aerial photographs to identify homes covered with blue tarps after Hurricane Irma struck Florida in September 2017. The tarps, commonly used to cover damaged roofs, served as a visible indicator of wind damage.

The researchers then compared properties built shortly before and after the 2001 Florida Building Code took effect. This approach was designed to isolate the effect of the stricter code from other differences between homes.

The analysis covered more than 500,000 homeowners. Properties subject to the newer code were 22% less likely to show wind damage. Among damaged properties, the measured severity of damage was 27% lower.

The study also examined property sales after the hurricane. Damaged homes sold before repairs were completed were less likely to sell and fetched 13.3% less on average than undamaged homes. That difference was about $29,400.

The findings provide evidence that stronger construction standards can reduce hurricane wind risk. However, the study used blue tarps as a proxy for damage and focused on homes affected by one hurricane in Florida, so the estimates should not automatically be applied to every storm or location.

The paper was published in the August 2026 issue of the American Economic Journal: Economic Policy.

At least seven explosions and low-flying aircraft were heard around 2 a.m. local time in Caracas. The southern area of the capital, near a major military base, was left without electricity.

Venezuelan Foreign Minister Yván Gil announced that President Maduro has signed a decree declaring a state of emergency and ordered all national defense plans to be implemented. The ministry said Venezuela "has been subjected to military aggression by the United States" and condemned attacks on civilian and military installations.

"The purpose of this attack is to seize Venezuela's strategic resources, in particular its oil and minerals," the Foreign Ministry said in a statement. "They will not be able to achieve this."

Colombian President Gustavo Petro called for an emergency meeting of the United Nations and the Organization of American States. "Caracas is under attack right now. Warn the whole world: Venezuela is under attack. They are bombing with missiles," Petro wrote on social media.

According to CBS News, Trump gave the military the green light to conduct land strikes days before the operation. Military officials had considered launching the mission on Christmas Day, but airstrikes in Nigeria against ISIS targets took precedence.

The Pentagon referred all requests for comment to the White House.

The strikes follow months of U.S. military buildup in the region, with approximately 15,000 troops and 11 naval vessels, including the USS Gerald R. Ford aircraft carrier, positioned in the Caribbean.

In the film, Peter Parker asks whether the device uses target-specific short interfering RNA, usually shortened to siRNA. These small RNA molecules can be designed to recognize a particular messenger RNA, or mRNA.

Messenger RNA carries instructions copied from DNA to the cell's protein-making machinery. An siRNA guide can direct a cellular complex known as RISC to matching mRNA. The complex then cuts the target, reducing production of the corresponding protein.

This process is often called gene silencing, but the name can be misleading. The treatment does not remove or switch off the underlying DNA. It lowers the output of a selected gene, and the effect can wear off.

RNA interference is established medicine, not science fiction. Several siRNA drugs have been approved by the US Food and Drug Administration for conditions including hereditary amyloidosis, acute hepatic porphyria, primary hyperoxaluria, high cholesterol, hemophilia and familial chylomicronemia syndrome.

The fictional application presents much bigger problems. Spider-Man's abilities would presumably involve many proteins, tissues and biological pathways. A single siRNA target would be unlikely to suppress strength, reflexes, senses and other traits together. Targeting several genes would also increase the challenge of predicting side effects.

Delivery is another major obstacle. Most approved siRNA medicines are designed to reach the liver, although one approved product uses lipid nanoparticles and researchers are testing ways to reach other organs. A whole-body treatment affecting muscles, nerves and other tissues would be far more difficult.

Real siRNA drugs also do not behave like an instant switch. They generally reduce rather than eliminate production of a protein. Their effects vary by drug and can last for weeks or months. Even after the silencing effect declines, cells may need time to rebuild the affected proteins.

The film therefore uses a genuine biological mechanism as a plausible idea, not a technology that medicine can currently reproduce. RNA interference can selectively reduce protein production, but it cannot safely fine-tune fictional superpowers on demand.

The talks took place in a working group under the Eurasian Economic Commission's Advisory Committee on Customs Regulation. Kuat Rakhimov, director of the commission's Department for Customs Legislation and Law Enforcement Practice, chaired the meeting.

One proposal from Kazakhstan would add coded information about relevant prohibitions and restrictions to declarations for express cargo and e-commerce goods. Standardized codes could allow customs systems to check some information automatically. The change may eventually shorten processing times, but the commission did not announce that it had been adopted or give a date for implementation.

Participants also considered a simplified declaration for goods sold by businesses in EAEU countries to individual buyers abroad through marketplaces and other online platforms. The proposal is intended to make customs procedures easier for exporters engaged in e-commerce.

The commission said it would prepare amendments to the rules for completing the e-commerce declaration. This means the measures remain under development.

The EEC has worked on special customs forms for express cargo and online trade for several years. Its Board approved an express-cargo declaration form and completion rules in 2018. It approved the structure and format of a separate declaration for e-commerce goods in December 2024.

The Victorian government announced the program on August 12 after vaccine doses arrived at Phillip Island. The rollout was due to begin once final regulatory approvals were in place.

Each selected penguin must be caught and identified, vaccinated, then caught again for a second dose. Little penguins return regularly to the same colonies and often to the same burrows, making this unusually large wild-bird vaccination effort possible.

Phillip Island Nature Parks said the project was believed to be the world's largest vaccination program involving wild birds. That description is the organiser's assessment, rather than a formally verified world record.

The Phillip Island colony contains about 40,000 little penguins. Their dense colonies could allow infection to spread quickly. The species is the world's smallest penguin, typically standing about 30 centimetres tall and weighing around 1.5 kilograms.

When the vaccination program was announced, the Victorian government said H5 bird flu had been detected in wild birds at several locations, including Phillip Island, but not yet in a little penguin. Subsequent reporting said a little penguin from Phillip Island had died with the virus before vaccinations began.

Vaccination cannot stop H5 bird flu from circulating among wild birds, and it will not protect every penguin. Authorities say it may reduce severe disease and deaths when used alongside surveillance, biosecurity and wildlife-response measures.

The vaccine contains inactivated virus and cannot cause bird flu. It stimulates an immune response, but protection is not guaranteed. The two-dose schedule is intended to strengthen that response. Individual birds must be monitored for adverse effects after vaccination.

Australia has also prepared vaccination programs for other priority native birds, particularly threatened species in zoos or closely managed populations. National authorities say H5 bird flu cannot feasibly be eradicated from wildlife following detections and evidence of local transmission, so the response focuses on monitoring and reducing harm.

The Australian government says the current risk to people remains low and that no H5 detections have been found in poultry or agricultural production. Members of the public should not touch sick or dead birds. Suspected cases can be reported to the Emergency Animal Disease Hotline on 1800 675 888.

The X1 took off from Plattsburgh International Airport and climbed to about 1,100 feet. Heart Aerospace said its four electric motors delivered more than one megawatt of power during the flight. The aircraft has a wingspan of 106 feet and weighed more than 25,000 pounds at takeoff.

According to the company, the batteries supplied about $5 worth of electricity during the flight. That figure covers energy alone. It does not include the much larger costs of developing, buying and operating an aircraft, such as maintenance, crew, airport fees, battery replacement and financing.

Heart describes the X1 as the largest fully electric aircraft yet flown. The claim refers to the aircraft’s overall scale, but there is no single universally used measure of aircraft size. The X1 is comparable in dimensions to a small regional airliner, although it was built as a technology demonstrator and did not carry passengers.

The aircraft flew under an experimental airworthiness certificate issued by the US Federal Aviation Administration. Its first flight was conducted within a restricted test envelope and included takeoff, a low-altitude climb, basic maneuvers and landing. A successful first flight does not demonstrate the range, reliability or regulatory compliance needed for commercial passenger service.

The X1 is helping Heart develop the ES-30, a proposed 30-seat hybrid-electric regional aircraft. Heart currently lists a planned all-electric range of 125 miles and a hybrid range of up to 500 miles. The company is targeting type certification in 2031. Those figures and the schedule are development goals, not demonstrated performance or regulatory approvals.

Battery weight remains one of the main barriers to fully electric airliners. Batteries store much less energy per unit of weight than jet fuel and do not become lighter as their charge is used. Heart therefore plans to combine electric propulsion with fuel-powered turboprop engines on the ES-30 for flights beyond its intended battery-only range.

The company says the ES-30 could reduce aircraft operating costs by more than 40% when it enters service. That estimate has not yet been demonstrated in commercial operations and depends on the final aircraft, energy prices, maintenance needs and certification requirements.

The X1 flight is an important engineering milestone for Heart, but it does not show that a battery-electric regional airliner is ready for airline service. Further flight testing and development will be needed before the company’s commercial plans can be assessed.

Belarusian President Alexander Lukashenko took part on 15 August in the opening ceremony of the international festival of ethnocultural traditions "Zov Polesia" ("Call of Polesia"), an event dedicated to the cultural traditions of the Polesia region, a historical area in southern Belarus.

Greeting participants, Lukashenko called the festival a bright and unique event. "According to historians, Polesia is the ancestral home of the Slavs," he said. "From here come our roots." He recalled that the festival was launched in 2010 as a reason for the three "brotherly peoples" — Belarusians, Russians and Ukrainians — to come together, and said all Slavs were welcome.

Origins and Identity

The president said the roots of the Belarusian people reach back to Turov, a town in the region, and that no politics could reverse that history. He said he had come to believe that the main features of the Belarusian character were formed in Polesia. "Poleshuks are cunning, smart, very hardworking and talented people," he said, using the traditional name for residents of the area.

Lukashenko said Belarusians are a nation that absorbed habits and traditions from Israel, the East, Europe and Kyivan Rus', and ordered that this be reflected in the National Museum now under construction in the centre of Minsk. "Culture Minister Markov is finishing the construction of the National Museum, and we must firmly underline this and define it forever," he said.

Festival and Peace

He praised the people of the region, saying that every visit to Pripyat Polesia fills him with admiration. He said the festival had become a calling card of the region and a holiday for friends and like-minded people.

"We are open and always glad to see guests, we remember our roots and are faithful to traditions," Lukashenko said, adding that the region's most important issue was peace and security. "War is very close. It is at your doorstep," he said.

Development and Recollections

The president recalled his first steps in office in Polesia, including mowing the Pripyat floodplain together with locals, after which they called him "one of us." He also described an early meeting in Lyaskovichi, an agro-town in the region, when an elderly woman asked him for help with bread. He said he ordered military bakeries to be moved there, and the first hot bread was produced.

Lukashenko said a previous revival program had been implemented and that a new development program for Polesia is now being funded with significant budget resources. He said the emphasis would be on roads and bridges and on concentrating development in agro-towns such as Lyaskovichi, where living conditions should be as good as in cities. "From you only one thing is needed — discipline, order and labour," he told residents.

The program is overseen by Mikhail Rusy, a native of Polesia, the president noted. He said the region has become a center of developed industry, vegetable growing and a cultural center with tourist potential.
