Architects don’t need AI, says high-tech pioneer Norman Foster

PARIS: British architect Norman Foster has spent six decades pushing the boundaries of technology with awe-inspiring modernist structures from California to Hong Kong, but he is yet to be convinced by the craze for artificial intelligence.

“Artificial intelligence at the moment has the ability to cheat, to invent,“ he told AFP in a recent interview in Paris, which is hosting a retrospective of his work.


“We live in a world which is physical, we inhabit buildings, streets, squares. That physicality, you can’t replicate by artificial intelligence.”

Foster has been shaping urban landscapes since the 1960s and won the Pritzker Prize, the equivalent of the Nobel Prize in architecture, in 1999.


His statement projects include Apple's giant ring-shaped headquarters in California, London's Wembley Stadium and Millennium Bridge, and Berlin's Reichstag.

Experts describe his practice, Foster and Partners, as possibly the most prolific in history, and the most adept at navigating changing trends and technologies.

“He conceives architecture almost as an organism balancing itself with the air, the sun, life,“ said Frederic Migayrou, curator of the Norman Foster exhibition at the Pompidou Centre in the French capital.

Yet he has not swerved controversy, irking climate campaigners with his keenness to build airports and his views on the environment.

'Hard facts'

He is a champion of urban living -- “people live longer in cities” -- but his vision for sustaining urban lifestyles has courted some criticism.

He supports nuclear power, saying it had not caused a single death and the world would only be able to tackle climate change “with hard facts, not emotion”.


He sees it as a vital part of the solution to the deprivation and poverty seen in megacities and overpopulated slums across the world.

“Many people gravitated to those cities because there are more opportunities,“ he said.

“The answer has to be an abundance of clean energy, and the cleanest, safest form of energy is nuclear.”

Hong Kong's Chek Lap Kok airport, opened in 1998, made a huge splash for his firm, and he has worked on several airports since -- much to the annoyance of climate activists, who see air travel as part of the problem.

Yet when he talks of his broader philosophy, the 87-year-old could easily make common cause with climate activists.

End of the sprawl


Surrounded by models of his greatest creations, he talked breezily about the development of cleaner, greener cities.

The pandemic accelerated a growing need for people to have access to outdoor spaces for eating and strolling, and for services within walking distance of their homes, he argued.

“The cities which are most popular... they fit that model, essentially it’s a European model born before the ascendency of the automobile,“ he said.

And the transformation of our relationship with cars is central to the reshaping of modern cities, he said.

“You have younger generations who are less interested in ownership, who will move towards ride-sharing and mobility more as a service,“ he said.

This was pushing us away from sprawling car-centric cities with rigid work-home zones to ones where buildings were multipurpose, reducing the need for commuting.

Despite his storied history, Foster, still a central figure in all these threads of modern design, is not keen to dwell on his achievements.

The Pompidou exhibition, which displays models of his buildings alongside exhibits that inspired their design, has allowed him to see hidden connections.

But understandably for someone who forged the “high-tech” architectural movement in the 1960s with fellow Briton Richard Rogers, what comes next is always more important than what has already gone.

“Overall, I’m more excited by the future than I am by the past.”

Six decades of works by the world renowned British architect who is often seen as a leader of the "high-tech" trend are now on display at the Centre Pompidou in Paris.

The largest retrospective of works by British architect, Norman Foster has opened at the Centre Pompidou in Paris, spanning the last six decades of his career.

Drawings, workbooks, scale models, prototypes and videos enable visitors to delve into 130 major projects on display in the centre, which itself is considered one of the first examples of the "High Tech" architectural trend that Foster helped pioneer.

The exhibition reviews the different periods of the architect’s work and highlights cutting-edge creations, such as the headquarters of the Hongkong and Shanghai Banking Corporation (Hong Kong, 1979-1986), the Carré d’Art (Nîmes, 1984-1993), Hong Kong International Airport (1992-1998) and Apple Park (Cupertino, United States, 2009-2017).

Sources of inspiration for Foster, including Fernand Léger, Constantin Brancusi, Umberto Boccioni and Ai Wei Wei are also presented in the exhibition.

Foster's creations were influenced by his time working with American architect, Richard Buckminster Fuller, who founded the concept of combining technology with the environment.

The exhibition traces these themes of sustainability and anticipation of the future:

"The birth of the practice in the 1960s coincided with the first signs of an awareness of the fragility of the planet. These were the green shoots of what would later be named The Green Movement," explains Foster.

"These principles may now be mainstream, but more than half a century ago, they were revolutionary and anticipated the reality of today. Throughout the decades, we have sought to challenge conventions, reinvent building types and demonstrate an architecture of light and lightness, inspired by nature, which can be about joy as well as being eco-friendly."

The exhibition runs until August 7, 2023, and is organised by the Centre Pompidou, with the participation of Foster + Partners and the Norman Foster Foundation.

Malian soldiers and unidentified foreign military personnel were likely to have executed at least 500 people during a five-day operation in the village of Moura in central Mali in March 2022, the UN Human Rights Office said on Friday. A UN report on the incident was released after a months-long investigation into the attack, which rights groups say is the worst atrocity in a 10-year-old conflict between Islamist groups and the army in which thousands have died and millions have been displaced.


France says 2 citizens held in Iran freed from prison, on way to Paris

Two French citizens imprisoned in Iran have been freed, France's foreign minister said Friday. Benjamin Briere and Bernard Phelan, who both had been held in a prison in Mashad, in northwest Iran, were heading to Paris, a statement from Foreign Minister Catherine Colonna said.

Paris (AFP) – Iran on Friday released two French citizens jailed in separate cases, France said, urging Tehran to release four others still detained in the Islamic republic.

Bernard Phelan, who also holds Irish nationality, and Benjamin Briere were freed from their prison in the northeastern city of Mashhad and are "on their way to France", Foreign Minister Catherine Colonna said.

There had been grave concerns about the health of both men, both of whom had been on hunger strikes to protest their conditions.

President Emmanuel Macron added on Twitter: "Free, finally. Benjamin Briere and Bernard Phelan can reunite with their loved ones. It's a relief".

The flightradar24.com website showed that the Dassault Falcon plane had taken off from Mashhad around 1100 GMT and was due to touch down at Paris Le Bourget airport -- no longer used for commercial flights -- after 1700 GMT.

Benjamin Briere's sister Blandine Briere, who has led the campaign for his release during her brother's two-year ordeal, told AFP: "We are avoiding a tragedy. I have no words to describe the joy we feel."

"We cannot tell you how relieved we are," added Phelan's sister Caroline in a statement.

The pair were among some two dozen foreigners jailed in Iran who campaigners see as hostages held in a deliberate strategy by Tehran to extract concessions from the West.
'Difficult ordeal'

Phelan, 64, a Paris-based travel consultant, was arrested in October in Mashhad and has been held ever since.

In April, he was jailed for six and a half years on national security charges strongly rejected by his family.

With Iran rocked by anti-regime protests since September, Phelan was accused of taking photos of a burned mosque and police officers, and sending images to a British newspaper, the family said.

Phelan went on a dry hunger strike in January to protest his detention, refusing both food and water. But he stopped the action at the request of his family, who feared he would die. They said his health had deteriorated considerably in detention.

"The last seven months have been a very difficult ordeal for Bernard and for his family and I am pleased and relieved that this is now at an end," said Irish Foreign Minister Micheal Martin.

Briere, 37, was first detained while travelling in Iran in May 2020 and later sentenced to eight years in prison for espionage.

Although acquitted by an appeals court, he remained in prison in a situation described as "incomprehensible" by his family.

Held like Phelan in the prison of Vakilabad in Mashhad, Briere also went on hunger strikes to protest his conditions.

Briere's France-based lawyer Philippe Valent said he had started his latest hunger strike on January 28.

"This release had to happen before there was a catastrophe. There was a real risk to his life," he told AFP.

'Regain full freedom'

Four more French citizens, described previously as "hostages" by the French foreign ministry, are still in prison by Iran.

Colonna said she had spoken earlier Friday to her Iranian counterpart Hossein Amir Abdollahian and made clear "France's determination to ensure that the other French citizens still detained in Iran also rapidly regain their full freedom".

Iran's foreign ministry described the release of Briere and Phelan as a "humanitarian action".

Macron added: "We will continue to work for the return of our compatriots still detained in Iran."

Cecile Kohler, a teacher, and her partner Jacques Paris were arrested in May last year and remain in prison accused of espionage charges their family deny.

Louis Arnaud, described by his family as an innocent traveller, was arrested in September. Another French citizen is confirmed to be held by Paris but has never been named.

French-Iranian academic Fariba Adelkhah was released from prison in February but appears still unable to leave the country.

Several US, German, British, Swedish and other European citizens also remain detained.

Colonna told a meeting of EU foreign ministers in Stockholm that Europe would work for the release of "all Europeans, too many unfortunately, detained without reason in Iran".
Increased tensions

The holding of foreigners by Tehran has increased tensions with the West at a time when the Islamic republic is also under scrutiny for its crackdown on the protest movement that erupted in September.

Talks between Iran and the West on reviving the 2015 deal on its nuclear programme are frozen.

Activists are also alarmed by a surge in the number of executions by Iran. On Saturday, Tehran hanged Swedish-Iranian dissident Habib Chaab on terrorism charges.

German citizen Jamshid Sharmahd and Iranian-Swedish national Ahmadreza Djalali also face execution after being sentenced to death in trials denounced as a sham by their families.

Portuguese parliament legalises euthanasia

Levi FERNANDES
Fri, 12 May 2023 

Decriminalising euthanasia has deeply divided Catholic Portugal

After a long battle, Portugal on Friday passed a law legalising euthanasia for people in great suffering and with incurable diseases, joining just a handful of countries around the world.

The issue has divided the deeply Catholic country and witnessed strong opposition from conservative President Marcelo Rebelo de Sousa, a devout churchgoer.

Under its provisions, people aged over 18 will be allowed to request assistance in dying if they are terminally ill and in intolerable suffering.

It will only cover those suffering "lasting" and "unbearable" pain unless they are deemed not to be mentally fit to make such a decision.

The law will only be applicable for nationals and legal residents and not extend to foreigners coming into the country to seek assisted suicide.

The euthanasia bill was approved by parliament four times in the last three years but sent back every time for a constitutional review due to opposition from the president.

The definitive version of the law was adopted on Friday with support from the governing Socialists, who hold an absolute majority in the chamber.

"We are confirming a law that has already been approved several times by a huge majority," said Socialist MP Isabel Moreira, a fervent advocate of legalising euthanasia.

The president now has a week to promulgate the new law. It could come into force by the autumn, Portuguese media said.

"We have at last come to the end of a long battle," Moreira told AFP earlier this week.

- Debate continues -

Rebelo de Sousa had vetoed earlier bills due to "excessively undefined concepts" and later said the language used to describe terminal conditions continued to be contradictory and needed to be clarified.

The new version of the law now provides that euthanasia is only authorised in cases where "medically assisted suicide is impossible due to a physical disability of the patient".

Rebelo de Sousa has asked lawmakers to specify who would "attest" to whether a patient was physically incapable of assisted suicide but lawmakers this time refused to modify the text.

Questions raised by the president can be addressed through implementing decrees, said Catarina Martins, the leader of the far-left Left Bloc.

Rebelo de Sousa himself said approval of the law "wasn't a great drama" and did not give rise to "constitutional problems".

The debate over medically assisted dying is far from over in Portugal.

"The adoption of this law has been relatively fast compared with other big countries," said Paulo Santos, a member of the pro-euthanasia group Right To Die With Dignity.

He warned a large number of doctors could raise moral objections to carrying out euthanasia, as they had done over abortions in 2007.

"There's a good chance euthanasia will lead to even stronger resistance," he told AFP.

For their part, critics of medically assisted dying regret that the issue has not been put to a referendum and hope opposition deputies will once again ask the constitutional court to look into the bill.

Euthanasia and assisted suicide are only allowed in a handful of countries, including the Benelux nations and Portugal's neighbour, Spain.

From our special correspondents in Iskenderun, Turkey – With just two days to go ahead of Turkey’s high-stakes presidential and parliamentary elections, the country is at a crossroads. President Recep Tayyip Erdogan is seeking an unprecedented third term in power but is facing a serious challenge in the shape of Kemal Kilicdaroglu, a member of the Muslim Alevi minority that has long faced discrimination and is yearning for change.

The opposition candidate’s faith and origins have been major talking points during the campaign – an unthinkable prospect in past decades, when Alevis faced significant discrimination and even persecution. His promise to build a more inclusive nation has resonated with a community that feels abandoned by the state and has tired of Erdogan's 20-year rule.

Ahead of the vote, our reporters Julie Dungelhoeff, Mohammed Farhat and Nadia Massih went to meet Alevis who survived February's devastating earthquakes – to listen to their stories and hear their hopes for Turkey’s future.

One of Kenya’s oldest lions speared to death

International By BBC News | 3h ago

The male lion, named Loonkiito, was speared by local herders in Olkelunyiet village on Wednesday night after preying on livestock.


One of the oldest lions in Kenya has died at the age of 19, authorities have said.

The male lion, named Loonkiito, was speared by local herders in Olkelunyiet village on Wednesday night after preying on livestock. The village borders Amboseli National Park - on the outskirts of the capital, Nairobi.

Kenya Wildlife Service (KWS) spokesperson Paul Jinaro told the BBC that the lion was old and frail and wandered into the village from the park in search of food.

Mr Jinaro could not confirm if it was the oldest lion in the country but noted it was "very old".

Lion Guardians, a conservation organisation, said Loonkiito was the oldest male lion in its ecosystem and possibly in Africa.

"He was a symbol of resilience and coexistence," the organisation said in a statement.


Paula Kahumbu, a wildlife conservationist and chief executive officer of WildlifeDirect, said she was pained by the killing of the lion and called for measures to protect wildlife in the country.


"This is the breaking point for human-wildlife conflict and we need to do more as a country to preserve lions, which are facing extinction," Ms Kahumbu told the BBC.
Hyundai takes 55% of hydrogen vehicle market in Q1

SEOUL, May 12 (UPI) -- South Korean automaker Hyundai Motor accounted for almost 55% of the hydrogen fuel-cell vehicle market in the first quarter of this year, according to business tracker SNE Research.

Hyundai's first-quarter sales of its hydrogen fuel-powered model Nexo increased 19.8% from a year ago. As a result, its market share rose from 47.7% to 54.6%, according to Thursday's report.

Japanese carmaker Toyota's Mirai took second place with a market share of 24.1%, followed by China's leading truck maker Foton and Chinese bus producer King Long.

Compared to electric vehicles, hydrogen vehicles have not shown as much success in garnering customers for the eco-friendly market, but the sector has been expanding at a solid pace.



The sector's annual sales passed 20,000 for the first time last year, and in the first quarter of 2023 increased another 4.5%.

Automotive powerhouses from around the globe are drawing up their own plans to fast-forward development of hydrogen vehicles to compete with the sector leader Hyundai.

Japan's Honda revealed that it was joining hands with General Motors to develop hydrogen fuel cell systems, while Toyota said it would be introducing more new models later this year.

BMW Group showed off a prototype of the iX5 Hydrogen. The German corporation unveiled its goal of increasing the mileage of hydrogen fuel cell vehicles while reducing their price to be competitive with EVs.

"My belief is that eventually hydrogen vehicles will become the go-to option for larger-size vehicles. But they still have a long way to go because there are so many challenges," Daelim University automotive Professor Kim Pil-soo told UPI News Korea.

"For example, it is too expensive to set up hydrogen stations. We also need to improve the way to access eco-friendly hydrogen fuels. Once these problems are dealt with, motorists might start to buy hydrogen cars en masse," he said.

Autonomy founder Mike Lynch extradited to U.S. on fraud charges

May 12 (UPI) -- Mike Lynch, a tech tycoon dubbed "Britain's Bill Gates" has been extradited to the United States to face criminal charges related to the $11 billion sale of his company Autonomy to Hewlett Packard.

The British Home Office confirmed that Lynch, 57, was extradited to the United States on Thursday as he arrived in San Francisco where he will be held on house arrest and guarded by private security he must foot the bill for himself.

Britain's High Court rejected Lynch's appeal of extradition on April 21, as the United States set his bail at $100 million, deeming him a "serious risk of flight."

"The bail set by the U.S. court is by U.K. standards extraordinarily high and is a clear example of the differing approaches of the U.S. and U.K. when it comes to prosecuting allegations of white collar crime," Thomas Garner, extradition partner at law firm Fladgate told CNBC.

Lynch was indicted by the U.S. Department of Justice in 2018 for conspiracy to commit wire fraud and thirteen counts of wire fraud.

He faces up to 20 years in prison on the U.S. charges after having been found liable for billions of dollars by a British judge in Hewlett Packard's civil lawsuit against him in January 2022.

Hewlett Packard asserted that Lynch had overvalued Autonomy by $700 million. HP wrote down the value of Autonomy by $8.8 billion a year after it bought the company.

HP expects to lose 3-4K employees in next three years

According to the U.S. grand jury indictment, Lynch and former Autonomy Vice President for Finance Stephen Keith Chamberlain engaged in a scheme to defraud buyers and sellers of Autonomy securities, including Hewlett Packard.

They allegedly made misrepresentations about their business and its financial condition, according to the U.S. Attorney's Office Northern District of California.

"Autonomy issued materially false and misleading quarterly and annual financial statements which the defendants allegedly provided to HP during the time that HP was considering whether to purchase Autonomy," Federal prosecutors said.

50 years into mission, Pioneer 11 helps solve mysteries of the universe

By Stefano Coledan

CAPE CANAVERAL, Fla., May 12 (UPI) -- As NASA and private industry prepare for a U.S. return to the moon after more than five decades, observers fondly remember early ventures that traveled deep into interstellar space and sparked excitement about exploring cosmic wonders.

One of the trailblazers was Pioneer 11, a robotic forerunner of such exploration and the first spacecraft to reach Saturn, the ringed and most iconic planet in the solar system.

Launched 50 years ago -- on April 5, 1973 -- Pioneer 11 is still going. Next destination: one of the stars in the Aquila (Eagle) constellation. Estimated time of arrival: 4 million years.

But Pioneer 11 already achieved its fame, with fly-bys of Jupiter and Saturn, sending back volumes of data about the distant planets and even discovering a couple more moons at the latter planet, as well as a new ring.

In comments on Pioneer 11's "spectacular" night launch, the late physicist James Van Allen, of the University of Iowa, said he expected the spacecraft to provide "a wealth of information even before it gets close to the approach with Saturn."

"This explorer will teach us a great deal about the solar system, never mind our own innate drive to learn," Van Allen said.

Plans for exploration


Approved in February 1969, the Pioneer missions were part of NASAs' unprecedented plans to explore the outer solar system. They involved twin spacecraft soaring past the orbit of Mars and the asteroid belt, to survey Jupiter and Saturn and to learn the physics of their surroundings.

They would do all that during amazingly high-speed flybys. The total budget: $350 million -- $2.4 billion in 2023 dollars.

Aerospace manufacturer TRW built Pioneer 10 and 11. While Pioneer 10 would fly to meet and survey Jupiter in early December 1973, Pioneer 11 used all the acceleration the giant planet would provide -- in a so-called gravity assist (a slingshot effect) -- yet it took 6 1/2 more years to reach Saturn in September 1979.

Both Pioneers crossed the space medium beyond the orbit of Mars and checked the asteroid belt so that scientists could evaluate possible hazards to missions much farther out in cosmic space.

And the twin spacecraft facilitated complex missions to Uranus and Neptune by their Voyager successors to the edge of the solar system and beyond.

During the spacecraft design phase performed in the 1960s, technology wasn't sophisticated enough to allow Pioneers 10 and 11 to enter orbit around the solar system's gas giants.

Pioneer 11, however, made the most of the boost from Jupiter, which hurled it up to a speed of 106,000 mph. Still, the spacecraft took until Sept. 1, 1979, to reach its closest approach to Saturn.

Its trajectory took it to thread the gap between the planet's top clouds and the edge of the innermost rings 13,000 miles overhead. The onboard instruments detected a thin, extra ring, as well as two extra moons.

Quick encounter

The closest encounter lasted only a few hours and coincided with one of the biggest discoveries of the mission.

When the onboard instruments observed Saturn's largest moon, Titan, signals from the spacecraft showed a puzzling aberration.

It didn't take long for the science team to interpret that measurement as a possibility that that moon had an atmosphere. They had suspected it for some time, and at that point they had reached a final conclusion.

"It wasn't just any atmosphere, it was a massive one," said Andrew Ingersoll, one of the mission lead scientists.

A professor emeritus of planetary science at the California Institute of Technology in Pasadena, Calif., Ingersoll explained that the atmospheric pressure, measured at that moon's surface, was surprisingly 1 1/2 times that of Earth.

"Finding out that it really had such a thick atmosphere was pretty interesting," he said. "It didn't tell us everything about Titan, but science continuously advances, if you have good instruments and good data."

Methane atmosphere


From that wealth of information, scientists established that Titan was similar to primordial Earth. There were some differences, however, as that atmosphere was made of methane.

At temperatures of minus-290 degrees F, it could mean something amazing: rain, rivers and lakes were all liquid methane, Ingersoll said.

That set the stage for a future mission, the Cassini-Huygens, in 2005. As the descent probe parachuted toward Titan's surface, cameras showed mountains and liquid basins, which confirmed that predictions from a quarter-century earlier were indeed correct.

Besides hauling panoply of scientific instruments, and just like its twin, Pioneer 11 carried a gold-plated aluminum plaque with greetings from Earth, just in case some extraterrestrial civilization ever found it.


This is the Pioneer 10 and 11's famed plaque that features a design engraved into a gold-anodized aluminum plate, 6-by-9 inches, attached to the spacecraft's antenna support struts to help shield it from erosion by interstellar dust. Devised by astronomer-author Carl Sagan, the plaques contained instructions to figure out where in the galaxy the Pioneers came from. Image courtesy of NASA Ames Research Center


Public relations stunt

Given the scientific prominence of the mission and the assured media interest, late astronomer and author Carl Sagan had a genius idea -- and a public relations stunt that NASA gladly accepted.

Finding room to improve, Sagan devised something more: including identical gold-plated LP records holding two hours of Earth sounds, including salutes in 58 languages.

"Hello from the children of planet Earth," Sagan's first son says in the LP's very first audio bite.

There was a lot of printed information on the metallic plaque, actual instructions --graphics and binary code -- to figure out where in the galaxy the Pioneers came from, Ingersoll said.

"Putting our location on a spacecraft that might be detected by aliens, was incredibly naïve," he said. "And this was something Sagan was perfectly aware of."

"It was amusing, and I think Sagan was having fun, also. In interstellar space, the chance of finding that little spacecraft is zero."

After 50 years, Pioneer 11 is an estimated 10.2 billion miles from Earth.


Last data in 1995


Whatever data Pioneer 11 still was sending suddenly stopped in late 1995. NASA officially announced that there was no way to confirm whether the spacecraft still was transmitting. And even NASA's original website has been archived.

As a reminder that Pioneer 11 is venturing out on its own, its NASA Solar System Exploration page's elapsed time is frozen at 22 years, 7 months, 17 days, 21 hours, 49 minutes -- the last time scientists received engineering data from the spacecraft, Nov. 24, 1995.

The final decision about Pioneer 11's ultimate path came straight from celestial mechanics, Ingersoll said.

"Mission planners had to make sure Pioneer 11 was on track to Jupiter, making sure it'd pick up its own speed, enough speed to make it to Saturn," he said.

And that decided the only trajectory geometry would allow.
