In a cabinet inside a modest laboratory in downtown Washington are rows and rows of ink samples in plastic squeeze bottles and small glass jars. To the untrained eye, it's just a bunch of blackish liquid with strange names like "moldy sponge" or "green grass." But to the U.S. Secret Service agents who use the samples, they are the clues that could save the president from an assassination attempt. Or stop a counterfeit ring. Or identify the D.C. sniper. Here's a look inside.

Two Barbary lion cubs have been born in a Czech zoo, a welcome addition to a small surviving population of a rare lion subspecies that has been extinct in the wild. Here's a closer look at the cubs.

Indonesia is sending dozens of containers of waste back to wealthy nations after finding it was contaminated with used diapers, plastic and other materials, adding to a growing backlash in Southeast Asia against being a dumping ground for the developed world's rubbish. Take a look at some of the rubbish.

The work of famed American architect Frank Lloyd Wright was recognized Sunday as eight of his buildings, including the Solomon R. Guggenheim Museum in New York City, Los Angeles' Hollyhock House and the Unity Temple in suburban Chicago, were added to the UNESCO World Heritage list. Here's a look at some of those buildings.

Aficionados of Western classical music have carved out a niche for themselves in Iran, where cultural expression remains tightly controlled by strict rules imposed after the 1979 Islamic Revolution. And perhaps surprisingly, musicians in their 20s and 30s perform for overwhelmingly young audiences. Here's a look at the symphony.

A life-size sculpture of the U.S. first lady has been unveiled in her hometown of Sevnica, drawing mixed reactions from the locals. The rustic figure was cut from the trunk of a linden tree, showing her in a pale blue dress like the one she wore at Donald Trump's presidential inauguration. Her face is depicted in a naive local style.

In one drawing, stick figures sleep on the ground under blankets watched by other figures with hats. Another picture has frowning stick figures behind what appears to be a chain-link fence. One shows two toilets in a small room. All of the drawings include imposing jail-like bars covering most of the canvas. They were done by children asked to depict their experience in Border Patrol custody and photographed by an American Academy of Pediatrics volunteer last week.

Men and women, young and old, make their way from around the city, the country and the world to this unassuming site, the burial place of Rabbi Menachem Mendel Schneerson, to pay their respects to the life and teachings of the revered Jewish leader of the Chabad-Lubavitch movement who died twenty-five years ago in June 1994. Let's take a closer look.

Millennium-old Cambodian artifacts displayed in a Japanese collector's home for two decades have been returned to the Southeast Asian country's National Museum. The 85 artifacts are mostly small bronze items and include statues of Buddha and the Hindu god Shiva, plus jars, ceramics and jewelry. Here's a look at the artifacts

A Lithuanian man and his wife have won the world "wife carrying" title, leaping over timber and wading through waist-high water to beat dozens of other couples for a second year running. The prize is the wife's weight in beer. Vytautas Kirkliauskas and his wife Neringa Kirkliauskiene cleared a grueling 253.5 meter (278-yard) obstacle course in 1 minute 6.72 seconds Saturday. That was just a tenth of a second ahead of former six-time world champion, Finland's Taisto Miettinen and his new partner Katja Kovanen.

The youngest member of Britain's royal family, Archie Harrison Mountbatten-Windsor, was christened at Windsor Castle on Saturday in a private ceremony — too private for some royal fans. The 2-month-old son of the Duke and Duchess of Sussex was baptized in the castle's private chapel by Archbishop of Canterbury Justin Welby, head of the Church of England.

The blast of a traditional firework on Saturday opened nine days of uninterrupted partying in Pamplona's famed running of the bulls festival. The blast was met by an eruption of joy from revelers, who sprayed each other with wine, staining in pink the traditional attire of white clothes and a red scarf.

Iraq on Friday celebrated the UNESCO World Heritage Committee's decision to name the historic city of Babylon a World Heritage Site in a vote held in Azerbaijan's capital, years after Baghdad began campaigning for the site to be added to the list. The 4,300-year-old Babylon — now mainly an archaeological ruin and two important museums — is where dynasties have risen and fallen since the earliest days of settled human civilization.

A small Ohio city is shooting for the moon in celebrating its native son's history-making walk 50 years ago this month. The hometown of Neil Armstrong has expanded its usual weekend "summer moon festival" to 10 days of Apollo 11 commemorations. Tens of thousands of visitors — the biggest crowds here since Armstrong's post-mission homecoming — are expected. There will be hot air balloons, '60s-themed evenings, concerts, rocket launches and a visit from five other Ohio astronauts. And "the world's largest moon pie," all 50 pounds of it.

Hong Kong's political divisions showed no sign of closing as students rebuffed an offer from city leader Carrie Lam to meet and a few thousand mothers rallied in support of young protesters who left a trail of destruction in the legislature's building at the start of the week. "Don't feel lonely, dad and mum will support you," read one of many handwritten messages held aloft at a "Hong Kong Mothers" rally Friday. Here are some photos from the rally.

Alaskans who routinely pack knit caps and fleece jackets in summer on Friday were swapping them for sunscreen and parasols amid a prolonged heat wave. Residents of Anchorage and other south-central cities completed a fifth week of above-normal temperatures, including a record high 90 degrees on Thursday in the state's largest city.

Joey "Jaws" Chestnut ate 71 wieners and buns to secure his 12th title at Nathan's Famous annual July Fourth hot dog eating contest on Thursday, just a few hot dogs shy of breaking the record he set last year. In front of a crowd of fans and facing 17 opponents, the California native far exceeded his nearest competitors, but didn't quite make or pass the 74-dog mark he reached in 2018. When asked how he felt after the contest, Chestnut, 35, said, "I feel like I should eat a couple more." Here are some photos from the annual event.

The national holiday to mark America's birth as a country was filled with parades, concerts, competitive eating and, of course, fireworks. Boston, Philadelphia, Washington, New York and other places around the country held massive celebrations with big name artists like Jennifer Hudson, Luke Bryan and Carole King. But Independence Day wasn't free from politics, as President Donald Trump's plan for a celebration in Washington featuring a display of tanks, fighter jets and a stealth bomber garnered support from some and protests from others. Here are some highlights from celebrations around the country.

Tens of thousands of people turned out for gay pride celebrations around the world last week, including a boisterous party in Mexico and the first pride march in North Macedonia's capital as well as one of the highest turnouts for New York City's parade. Here's a look at some of the celebrations.

Competing demonstrations spilled into the streets of downtown Portland on Saturday, with fights breaking out in places as marchers clashed. At least three groups had planned rallies or demonstrations at different sites in the city, including members of the so-called Proud Boys and anti-fascist groups that include "antifa," and the fights occurred when participants of the opposing groups met. Here are some photos of the march.

Peter van Wingerden's dairy farm smells just like any other farm — the rich aroma of cow manure and grass hangs in the air around the unusual stable housing the cattle. The farm itself is far from traditional. Moored in a small harbor in Rotterdam's busy port, the farm is a futuristic three-story floating structure where one robot milks the cows and another automatically scoops up the manure that gives the enterprise its familiar smell. Here are some photos of the dairy.

A motorcyclist who was among seven killed in a collision with a pickup truck last week was a family man, proud Marine and dedicated public servant, mourners said Friday at a funeral that drew about 200 people, including leather-clad bikers and law enforcement officers. The funeral for Michael Ferazzi, 62, of Contoocook, New Hampshire, was held at a church in Plymouth, Massachusetts. The rumbling of motorcycles echoed through town as dozens of bikes made their way to the service.

Crews are working around the clock at a NASA rocket factory, intent on meeting a new fall 2020 deadline to test launch a mega-rocket designed to propel astronauts to the moon and beyond, a space agency official said Friday. "I came out here in the middle of the night ... talking to people who were working on the engine section, working hard through the night," NASA Deputy Administrator James Morhard said on a press tour at New Orleans' Michoud Assembly Center.

He was born in a London pub and now his clones are floating all over the U.S. — quite literally President Donald Trump increasingly is being tailed and trolled by an angry diaper-clad caricature armed with a cell phone. He's Baby Trump, the blimp who has become synonymous with resistance to the American president. The origins story for Baby Trump began ahead of the president's visit to London last year when a group of activists gathered at a local pub to brainstorm ideas for a protest statement sure to get under Trump's skin. They succeeded beyond their wildest expectations, with a 20-foot blimp that flew near Parliament during the protests surrounding Trump's first visit to the United Kingdom and made a return appearance this summer when the president came for a state visit.

Three astronauts safely returned to Earth on Tuesday after spending more than six months aboard the International Space Station. The Soyuz capsule with astronauts from Canada, Russia and the United States landed in the steppes of Kazakhstan at 8:47 a.m., less than a minute ahead of the scheduled time, on Tuesday after a 3 ½ hour flight from the orbiting lab.

Orangutans at a Vienna zoo got buckets of water, lemurs in Rome enjoyed fruit icicles and a polar bear took to a pool in Germany as much of Europe sweltered Tuesday in an early summer heat wave. Authorities warned that temperatures could top 104 Fahrenheit in some parts of the continent over the coming days, the effect of hot air moving northward from Africa.

Malaysia authorities have arrested four Indians and seized more than 14 kilograms of drugs and over 5,000 turtles from their luggage at the Kuala Lumpur airport. Senior customs official Zulkurnain Mohamed Yusof said Wednesday that agents found a total 5,255 red-ear slider baby turtles kept in small baskets from the luggage of two Indian nationals who flew in from Guangzhou, China on an AirAsia flight on June 20.

Doctors in Rome are warning of possible health hazards caused by overflowing trash bins in the city's streets, as the Italian capital struggles with a renewed garbage emergency aggravated by the summer heat. Trash disposal is a decades-long problem for the Eternal City. Rome was left with no major site to treat the 1.7 million metric tons of trash it produces every year since the Malagrotta landfill was closed in 2013.

Dancers, musicians and revelers have watched the sun flicker over the horizon at Stonehenge, celebrating the summer solstice at the Neolithic stone circle.

His sister, Lijana Wallenda, joined him recently for the first time since her near-fatal accident in 2017, when she broke nearly every bone in her face.

Thousands of supporters of LGBT rights have marched through the center of Kiev, the Ukrainian capital, under a heavy police presence to separate them from opponents. Here are some photos from the parade.

Federal investigators will review repair and inspection records on the skydiving plane that became inverted before crashing shortly after takeoff on Oahu's North Shore, killing all 11 people on board in the deadliest civil aviation accident since 2011. The same plane that crashed Friday sustained substantial damage to its tail section in a 2016 accident while carrying skydivers over Northern California.

The 12 young Thai soccer players and their coach who grabbed global attention last year when they were trapped in a flooded cave for more than two weeks have marked the anniversary of their ordeal start with a religious ceremony.

Scamp the Tramp will never win a beauty contest. But he's won an ugly one. The bug-eyed, dreadlocked pooch took top honors June 21 at the 31st annual World's Ugliest Dog Contest. Here's a look at some of this year's ugliest dogs.

Firefighters, police and a veterinary clinic combined forces to rescue a red squirrel that had gotten its tiny head stuck in a manhole cover in the western German city of Dortmund.

A study of whales and dolphins that have washed up dead in Greece over a 20-year period has found alarmingly high levels of plastic trash — mostly bags — in the animals' stomachs, which can condemn them to a slow and painful death. In the worst case, a researcher said Friday, a 17-foot young sperm whale beached on the Aegean island of Mykonos had swallowed 135 plastic items weighing a total of 7 pounds. This blocked its stomach, grossly distending it, while the animal itself was emaciated and had starved to death.

Authorities say a black bear somehow locked itself inside a Montana home and then nestled onto a closet shelf that wasn't too hard, wasn't too soft, but just right for a nap.

Explosions and a blaze at the largest oil refinery on the East Coast sent a fireball into the sky and shook homes before dawn Friday, though authorities reported only a few minor injuries and said the air was safe to breathe. The fire at the Philadelphia Energy Solutions Refining Complex was deemed contained and controlled but continued to burn late Friday afternoon

A first-of-its-kind public campaign finance program in Seattle gives voters vouchers worth $100 to pass on to any candidate they want. Now in its second election cycle, advocates say the program can level the political playing field, although its first round in Seattle showed mixed results.

Opponents of President Donald Trump's reelection announcement Tuesday in Florida rebuked his administration's policies at a rally outside a gay bar with performances by a mariachi band and a drag queen, speeches by a transgender woman and women who had abortions and the appearance of a 20-foot-high blimp of a scowling Trump in a diaper. "The goal is to get under his skin," said Mark Offerman, the handler of the blimp known as "Baby Trump." Here's a look at the protest.

Jabbing at the press and poking the eye of the political establishment he ran against in 2016, President Donald Trump officially kicked off his reelection campaign Tuesday with a grievance-filled Florida rally that focused more on settling scores than laying out his agenda for a second term. Addressing a crowd of thousands at Orlando's Amway Center, Trump complained he had been "under assault from the very first day" of his presidency by a "fake news media" and "illegal witch hunt" that had tried to keep him and his supporters down. Here are a few photos from the rally.

Waiting outside a federal courthouse, photographer Tom Fox took in Dallas' 8 a.m. bustle. People dressed for work got out of cars. A homeless man danced on a street pole. But when what initially sounded like a truck backfiring clarified into gunshots, the routine assignment for a veteran journalist morphed in a moment. As shots echoed off the tall buildings, an armed officer dashed past The Dallas Morning News photographer. A man came around the corner half a block away and Fox pulled out his long lens — focusing in on green military-style garb, a mask and a belt full of ammunition. The gun barrel swung around. Fox squeezed off a last frame. And he ran for cover behind a column in the building's façade. Here are some of the photos he captured.

This grand hotel still manages to hold onto a flicker of its old majesty despite the mortal shell craters and bullet holes scarring its sandstone facade. Amid war in the summer of 1974 that cleaved Cyprus along ethnic lines, United Nations peacekeepers took over the Ledra Palace Hotel and instantly turned it into an emblem of the east Mediterranean island nation's division. It's been 45 years since the pitter-patter of glitterati high-heels on the hotel's floors was replaced by the thud of soldiers' combat boots. Here's a closer look at the hotel.

Nenette, one of the world's oldest Borneo orangutans in captivity, has celebrated her 50th birthday at a zoo in Paris, where she has lived almost all her life. Birthday cake, wrapped boxes and visitors singing "Happy Birthday" were part of the party held Sunday for Nenette at Menagerie, a zoo in the Jardin des Plantes gardens. Here are some photos from her party.

Hong Kong citizens marched for hours Sunday in a massive protest that drew a late-in-the-day apology from the city's top leader for her handling of legislation that has stoked fears of expanding control from Beijing in this former British colony. Nearly 2 million of the city's 7 million people turned out, according to estimates by protest organizers. Here are some images from the protests.

Around 100 works spanning Rembrandt's career are going on show in the German city of Dresden in an exhibition marking the 350th anniversary of the Dutch artist's death. The exhibition at the Kupferstich-Kabinett museum opened Friday and runs through Sept. 15.

Greece's education and religion minister says the country's long-delayed first state-sponsored mosque is likely to begin operating in September, about three years after its construction was approved by parliament. Kostas Gavroglou spoke Friday during a visit to the nearly complete mosque on the outskirts of Athens' city center, accompanied by representatives of the Muslim community. Its construction has been controversial, with some opposing a mosque in the Greek capital.

The bitter rivalry between Cambodian strongman Hun Sen and his self-exiled chief political rival Sam Rainsy has sometimes played out in deadly violence. But on Sunday, soup rather than blood was likely to be spilled. The two titans of Cambodian politics normally agree over nothing but made stunningly similar calls to their followers this past week. They both said all Cambodians should gather with their neighbors on Sunday and sit for a meal of num banh chok, a popular Cambodian rice noodle soup usually eaten at breakfast.
