The Expo 2025 opened in Osaka on Sunday with more than 10,000 people singing Beethoven's Ninth Symphony to celebrate the start of the six-month event that Japan hopes will unite the world divided by tensions and wars.

Here is what to know about the Expo 2025 Osaka:

What is Expo 2025 Osaka about? The Osaka Expo is held at Yumeshima, which means "dream island," a reclaimed industrial waste burial site in the Osaka Bay, where participants from more than 160 countries, regions and organizations showcase their futuristic exhibits inside about 80 pavilions of unique architecture.

"Creating a future society for our lives" is the main theme. It is Osaka's second Expo after the hugely successful 1970 event that attracted 64 million visitors, a record until Shanghai in 2010.

Organizers expect 28 million visitors through mid-October, though ticket sales have been slow, with about 9 million sold in advance, short of an initial target of 14 million.

"It’s been 55 years since the last Expo in Osaka. I've been looking forward to it," said Daiki Chiba, who traveled from Sendai, about 900 kilometers (560 miles) northeast of Osaka.

Many visitors carried Myaku-Myaku mascots or wore clothes matching its colors — red, blue and white — to get in the mood.

What does it mean to hold Expo amid global tensions? The Expo comes only four years after Japan struggled to host the no-audience Tokyo Olympics during the coronavirus pandemic.

It opens in the wake of trade wars and fears of a global economic downturn sparked by US President Donald Trump's tariffs, the three-year Russian invasion of Ukraine and Middle East conflicts.

Prime Minister Shigeru Ishiba compared the global tensions to a "national crisis" and said that Trump's tariffs, especially the 25% duty on automobiles, would be a blow to all industries and Japan's economy.

Still, Japan wants to turn the pinch into a chance.

"I think the timing is actually quite fitting," said Sachiko Yoshimura, head of Expo 2025 global communications. "Holding the Expo now could eventually help to address the divisions in the world. ... I believe this Expo in Japan might actually lead to stronger international relationships and improvements."

What is the Grand Ring? The iconic ring, designed by architect Sou Fujimoto, is a lattice-like structure encircling the venue and recognized by the Guinness World Records as the largest wooden architecture. It is 20 meters (65 feet) high and has a 2-kilometer (1.2-mile) circumference.

The costly ring takes up more than 14% of the Expo's total spending of 235 billion yen ($1.64 billion) and has triggered public criticism.

The total cost nearly doubled from the initial estimate largely due to the weaker yen, causing construction delays. Several pavilions, including those of Nepal, India, Vietnam and Chile, were not ready for the opening.

The ring is supposed to be partially reusable, reflecting the theme of creating a sustainable future.

What are other highlights? Exhibits of cutting-edge technology, such as robots and flying cars, as well as pop culture like Hello Kitty and Gundam, are among the highlights.

"Pavilions all look amazing," said Laurel Sylvester from New Zealand, visiting with her husband and two children. Her family is interested in ocean sustainability and planned to visit the Blue Ocean Dome. She said the boys are "super excited to have their photo with the (big Gundam) robot and some of the interesting tech things that are going on."

A small artificial heart made from induced pluripotent stem cells, or iPS, demonstrated a heartbeat at a Japanese health care pavilion. At the Future of Life pavilion, visitors can interact with robots. A human washing machine that was a sensation at the 1970 expo returned with a high-tech makeover.

The US pavilion focuses on space travel. Its lunar stone from the Apollo 12 mission, a sensation at the 1970 expo, was back on display.

China, also highlighting space technology, exhibits soil samples from its lunar missions.

Carrying a "Not for sale" sign and decorated with its blue-and-yellow national flags, Ukraine attracted many visitors with a globe and other items carrying barcodes. By scanning them, visitors can see videos showing people's lives at war and their reconstruction effort.

Dymtro Liuyi, Ukrainian creative director, said his country's participation was undecided until December due to the war. The preparation was finished Sunday morning, he said, showing blue paint on his fingers.

What is Myaku-Myaku? With its blue face encircled by red balls, some of them eyeballs, the mysterious, smiley creature Myaku-Myaku welcomes visitors.

The imaginary creature was born from the fusion of cells and water in a small spring in the Kansai region, organizers say. The friendly but clumsy character can transform into various shapes and is good at finding a rainbow after the rain.

Long known for its olives and seaside charm, the southern Greek city of Kalamata has found itself in the spotlight thanks to a towering mural that reimagines legendary soprano Maria Callas as an allegory for the city itself.

The massive artwork on the side of a prominent building in the city center has been named 2025’s “Best Mural of the World” by Street Art Cities, a global platform celebrating street art.

Residents of Kalamata, approximately 240 kilometers (150 miles) southwest of Athens, cultivate the world-renowned olives, figs and grapes that feature prominently on the mural.

That was precisely the point.

Vassilis Papaefstathiou, deputy mayor of strategic planning and climate neutrality, explained Kalamata is one of the few Greek cities with the ambitious goal of becoming climate-neutral by 2030. He and other city leaders wanted a way to make abstract concepts, including sustainable development, agri-food initiatives, and local economic growth, more tangible for the city’s nearly 73,000 residents.

That’s how the idea of a massive mural in a public space was born.

“We wanted it to reflect a very clear and distinct message of what sustainable development means for a regional city such as Kalamata,” Papaefstathiou said. “We wanted to create an image that combines the humble products of the land, such as olives and olive oil — which, let’s be honest, are famous all over the world and have put Kalamata on the map — with the high-level art.”

“By bringing together what is very elevated with ... the humbleness of the land, our aim was to empower the people and, in doing so, strengthen their identity. We want them to be proud to be Kalamatians.”

Southern Greece has faced heatwaves, droughts and wildfires in recent years, all of which affect the olive groves on which the region’s economy is hugely dependent.

The image chosen to represent the city was Maria Callas, widely hailed as one of the greatest opera singers of the 20th century and revered in Greece as a national cultural symbol. She may have been born in New York to Greek immigrant parents, but her father came from a village south of Kalamata. For locals, she is one of their own.

This connection is also reflected in practice: the alumni association at Kalamata’s music school is named for Callas, and the cultural center houses an exhibition dedicated to her, which includes letters from her personal archive.

Artist Kleomenis Kostopoulos, 52, said the mural “is not actually called ‘Maria Callas,’ but ‘Kalamata’ and my attempt was to paint Kalamata (the city) allegorically.”

Rather than portraying a stylized image of the diva, Kostopoulos said he aimed for a more grounded and human depiction. He incorporated elements that connect the people to their land: tree branches — which he considers the above-ground extension of roots — birds native to the area, and the well-known agricultural products.

“The dress I create on Maria Callas in ‘Kalamata’ is essentially all of this, all of this bloom, all of this fruition,” he said. “The blessed land that Kalamata itself has ... is where all of these elements of nature come from.”

Creating the mural was no small feat. Kostopoulos said it took around two weeks of actual work spread over a month due to bad weather. He primarily used brushes but also incorporated spray paint and a cherry-picker to reach all edges of the massive wall.

Papaefstathiou, the deputy mayor, said the mural has become a focal point.

“We believe this mural has helped us significantly in many ways, including in strengthening the city’s promotion as a tourist destination,” he said.

Beyond tourism, the mural has sparked conversations about art in public spaces. More building owners in Kalamata have already expressed interest in hosting murals.

“All of us — residents, and I personally — feel immense pride,” said tourism educator Dimitra Kourmouli.

Kostopoulos said he hopes the award will have a wider impact on the art community and make public art more visible in Greece.

“We see that such modern interventions in public space bring tremendous cultural, social, educational and economic benefits to a place,” he said. “These are good springboards to start nice conversations that I hope someday will happen in our country, as well.”

Nine skiers were missing after an avalanche in California's Sierra Nevada mountains on Tuesday, but six others, who had been stranded, have since been rescued, authorities said.

The avalanche swept the Castle Peak area of Truckee, California, about 10 miles north of Lake Tahoe, at about 11:30 a.m. Pacific time, engulfing a group of skiers, according to a Facebook statement posted by the Nevada County Sheriff's Office.

Those rescued have varying injuries and two were ‌sent to a hospital ‌for treatment.

The sheriff's office revised the number of ‌people ⁠in the group to ⁠15 from an earlier estimate of 16, adding that no further updates were expected on Tuesday evening.

If all nine of the missing skiers should perish, the incident would rank among the deadliest single avalanches on record in the United States. The Colorado Avalanche Information Center has tallied six US avalanche fatalities so far this season.

Avalanches have claimed an average of 27 lives ⁠each winter in the United States over the past ‌decade, the center reported.

A winter storm warning ‌was in effect for much of northern California on Tuesday, with heavy snow ‌forecast in the upper elevations of the Sierra Nevada.

The Sierra Avalanche Center ‌had posted an alert before dawn on Tuesday, warning of a "high avalanche danger" in the ski region, the sheriff's statement said.

"I don't think it was a wise choice," Greene said of the decision of a ski tour company to take paying ‌customers out into the backcountry under such conditions, adding, "but we don't know all the details yet." He declined to ⁠name the company involved.

Rescue ⁠ski teams were dispatched to the avalanche zone from the Boreal Mountain Ski Resort and Tahoe Donner's Alder Creek Adventure Center.

The survivors had taken refuge in a makeshift shelter, constructed partly from tarpaulin sheets and communicated with rescuers via radio beacon and text messaging.

Greene declined to say how many of the ski guides and how many of their customers were among the missing.

Weather conditions remained hazardous in the Sierra backcountry slopes, with additional avalanche activity expected through Tuesday night and into Wednesday, according to the sheriff's statement.

California Governor Gavin Newsom was briefed on the avalanche, and state authorities were "coordinating an all-hands search-and-rescue effort" in conjunction with local emergency teams, his office said in a posting on X.

An ungainly barrel of a shark cruising languidly over a barren seabed far too deep for the sun’s rays to illuminate was an unexpected sight.

Many experts had thought sharks didn’t exist in the frigid waters of Antarctica before this sleeper shark lumbered warily and briefly into the spotlight of a video camera, researcher Alan Jamieson said this week. The shark, filmed in January 2025, was a substantial specimen with an estimated length of between 3 and 4 meters (10 and 13 feet).

“We went down there not expecting to see sharks because there’s a general rule of thumb that you don’t get sharks in Antarctica,” Jamieson said.

“And it’s not even a little one either. It’s a hunk of a shark. These things are tanks,” he added.

The camera operated by the Minderoo-UWA Deep-Sea Research Centre, which investigates life in the deepest parts of the world’s oceans, was positioned off the South Shetland Islands near the Antarctic Peninsula. That is well inside the boundaries of the Antarctic Ocean, also known as the Southern Ocean, which is defined as below the 60-degree south latitude line.

The center on Wednesday gave The Associated Press permission to publish the images.
The shark was 490 meters (1,608 feet) deep where the water temperature was a near-freezing 1.27 degrees Celsius (34.29 degrees Fahrenheit).

A skate appears in frame motionless on the seabed and seemingly unperturbed by the passing shark. The skate, a shark relative that looks like a stingray, was no surprise since scientists already knew their range extended that far south.

Jamieson, who is the founding director of the University of Western Australia-based research center, said he could find no record of another shark found in the Antarctic Ocean.

Peter Kyne, a Charles Darwin University conservation biologist independent of the research center, agreed that a shark had never before been recorded so far south.

Climate change and warming oceans could potentially be driving sharks to the Southern Hemisphere’s colder waters, but there was limited data on range changes near Antarctica because of the region’s remoteness, Kyne said.

The slow-moving sleeper sharks could have long been in Antarctica without anyone noticing, he said.

“This is great. The shark was in the right place, the camera was in the right place and they got this great footage,” Kyne said. “It’s quite significant.”

The sleeper shark population in the Antarctic Ocean was likely sparse and difficult for humans to detect, Jamieson said.

The photographed shark was maintaining a depth of around 500 meters (1,640 feet) along a seabed that sloped into much deeper water. The shark maintained that depth because that was the warmest layer of several water layers stacked upon each other to the surface, Jamieson said.

The Antarctic Ocean is heavily layered, or stratified, to a depth of around 1,000 meters (3,280 feet) because of conflicting properties including colder, denser water from below not readily mixing with fresh water running off melting ice from above.

Jamieson expects other Antarctic sharks live at the same depth, feeding on the carcasses of whales, giant squids and other marine creatures that die and sink to the bottom.

There are few research cameras positioned at that specific depth in Antarctic waters.

Those that are can only operate during the Southern Hemisphere summer months, from December through February.

“The other 75% of the year, no one’s looking at all. And so this is why, I think, we occasionally come across these surprises,” Jamieson said.
