A Roman Gladiator and a Lion Met in Combat. Only One Walked Away.
At last, proof of classical combat between man and beast has been found in the form of a skeleton from a Roman settlement in Britain. The skeleton was discovered 20 years ago, in an excavation spurred by a couple hoping to renovate the yard of their home in the English city of York. An initial survey turned up evidence of an ancient cemetery, halting the construction plans.
'Britain is rich with Roman archaeology,' said Tim Thompson, an anthropologist at Maynooth University in Ireland and an author of a paper that describes the discovery in the journal PLOS One. 'You pretty much can't shove a spade in the ground without hitting something ancient and archaeological.'
The larger site contained the buried remains of more than 80 individuals, and many of their bodies showed signs of trauma. The demographics of the deceased, the types of injuries in their bones and the manner in which they were interred suggested that they had fought as gladiators about 1,800 years ago, when what is now York was an outpost of the Roman Empire.
One skeleton in particular, identified by researchers as 6DT19, had unusual wounds: small indentations in the hip bones.
Other researchers had noted that these notches looked like bite marks from a large animal, perhaps a lion.
To determine if the indentations of 6DT19's hip really were bite marks, Thompson and his colleagues first had to collect data on what the bite marks of large mammals look like. For that, they made a somewhat unusual request of several British zoos: a chance to examine their lions' leftovers.
By shining a grid of light on the bones gnawed on by zoo animals, the researchers created a map of the dimensions and depth of the animals' bites. They then created a map of 6DT19's hip bones and compared the bite marks left by the different animals with the indentations on the skeleton. Sure enough, the Roman combatant's injuries were best explained by a lion's bite.
However, the hip bite probably isn't what killed 6DT19. 'We think the individual was incapacitated in some way, and then the animal came along, bit and dragged the body away,' Thompson said. — KATE GOLEMBIEWSKI /NYT

Alexandria is most at risk along the Mediterranean Basin
From her ninth-floor balcony over Alexandria's seafront, Eman Mabrouk looked down at the strip of sand that used to be the wide beach where she played as a child. "The picture is completely different now," she said. The sea has crept closer, the concrete barriers have grown longer, and the buildings around her have cracked and shifted. Every year, 40 of them collapse across Egypt's second city, up from one on average a decade ago, a study shows. The storied settlement that survived everything from bombardment by the British in the 1880s to attacks by crusaders in the 1160s is succumbing to a subtler foe infiltrating its foundations. The warming waters of the Mediterranean are rising, part of a global phenomenon driven by climate change. In Alexandria, that is leading to coastal erosion and sending saltwater seeping through the sandy substrate, undermining buildings from below, researchers say. "This is why we see the buildings in Alexandria being eroded from the bottom up," said Essam Heggy, a water scientist at the University of Southern California who co-wrote the study published in February describing a growing crisis in Alexandria and along the whole coast. The combination of continuous seawater rises, ground subsidence, and coastal erosion means Alexandria's coastline has receded on average 3.5 metres a year over the last 20 years, he told Reuters."For many people who see that climate change is something that will happen in the future and we don't need to worry about it, it's happening right now, right here," Heggy said. The situation is alarming enough when set out in the report - "Soaring Building Collapses in Southern Mediterranean Coasts" in the journal "Earth's Future". For Mabrouk, 50, it has been part of day-to-day life for years. She had to leave her last apartment when the building started moving."It eventually got slanted. I mean, after two years, we were all ... leaning," she told Reuters. "If you put something on the table, you would feel like it was rolling. "BARRIERS, BULLDOZERS, CRACKS Egypt's government has acknowledged the problem and promised action. Submerged breakwaters reduce coastal wave action, and truckloads of sand replenish stripped beaches. Nine concrete sea barriers have been set up "to protect the delta and Alexandria from the impact of rising sea waves," Alexandria's governor, Ahmed Khaled Hassan, said. The barriers stretch out to sea, piles of striking geometric shapes, their clear curves and lines standing out against the crumbling, flaking apartment blocks on the land. Authorities are trying to get in ahead of the collapses by demolishing buildings at risk. Around 7,500 were marked for destruction, and 55,000 new housing units will be built, Prime Minister Mostafa Madbouly told a crowd as he stood on one of the concrete barriers on July 14."There isn't a day that passes without a partial or complete collapse of at least one building that already had a demolition order," Madbouly said. Some are hopeful the measures can make a difference."There are no dangers now ... They have made their calculations," coffee shop owner Shady Mostafa said as he watched builders working on one of the barriers. Others are less sure. Alexandria's 70-km (45-mile) long coastal zone was marked down as the most vulnerable in the whole Mediterranean basin in the February report. Around 2% of the city's housing stock - or about 7,000 buildings - were probably unsafe, it added. Every day, more people are pouring into the city - Alexandria's population has nearly doubled to about 5.8 million in the last 25 years, swollen by workers and tourists, according to Egypt's statistics agency CAPMAS. Property prices keep going up, despite all the risks, trackers levels are rising across the world, but they are rising faster in the Mediterranean than in many other bodies of water, partly because the relative shallowness of its sea basin means it is warming up faster. The causes may be global, but the impacts are local, said 26-year-old Alexandria resident Ahmed al-Ashry."There's a change in the buildings, there's a change in the streets," he told Reuters. "Now and then, we try to renovate the buildings, and in less than a month, the renovations start to fall apart. Our neighbours have started saying the same thing: that cracks have started to appear."

A handshake in orbit 50 years ago transformed the space race
Some 140 miles above France, American astronauts opened a spacecraft hatch and found themselves face to face with cosmonauts from the Soviet Union. 'Glad to see you,' Col. Alexei Leonov spoke in accented English to Brig. Gen. Thomas Stafford of NASA. 'Ah, hello, very glad to see you,' Stafford responded in his own accented Russian. The two men then shook hands. Today, Russian and American astronauts routinely share rides to the International Space Station, no matter the geopolitical conflict that divides their nations. But in the summer of 1975, seeing two men from rival nations greet each other in orbit across a bridge between their docked spacecraft was a powerful and unprecedented gesture witnessed by millions on the world spinning below. The handshake, which occurred 50 years ago on July 17, defined the Apollo-Soyuz Test Project, the first international human spaceflight. That simple symbol of partnership between bitter competitors remains an enduring legacy of the mission. 'It's amazing to think that two opposed countries with different systems and cultures, essentially ready to destroy each other, can somehow cooperate and do this highly technical, complicated mission,' said Asif Siddiqi, a professor of history at Fordham University and an expert on Russian space history. A generation after the orbital handclasp, the Soviets and the United States would come together to build the ISS. The aging space outpost's days are finite, and there are no immediate plans for Russia and the U.S. to sustain their cooperation in human spaceflight. The U.S. also sees itself as competing with China for dominance in space. But experts like Siddiqi see reasons for hope on the 50th anniversary of the Apollo-Soyuz mission. 'Whenever people tell me that this would never happen today, I always think, Well, that's what people said in the late '60s,' Siddiqi said. 'Androgynous' Dock Early in the space age, as America raced to catch up to the Soviet Union, a partnership in space had been proposed. In September 1963, speaking before the United Nations General Assembly two months before his assassination, President John F. Kennedy floated a joint mission to the moon. 'Why, therefore, should man's first flight to the moon be a matter of national competition?' he asked. 'Surely we should explore whether the scientists and astronauts of our two countries — indeed of all the world — cannot work together in the conquest of space.' This dream was deferred, and the U.S. would overtake the Soviets in the moon race with the successful Apollo 11 mission in 1969. Oddly, the American moon landing may have created a new window for cooperation. Public support for the Apollo missions fell, and the program was cut short after the Apollo 17 mission in 1972. That left the U.S. space program without an immediate objective. In parallel, both nations' reputations were tarnished abroad, the Soviet Union by its invasion of Czechoslovakia, and America by its involvement in the Vietnam War. That created an additional motivation to jointly reassert each country's status atop the global hierarchy. 'They needed to lift themselves and cooperate to show the rest of the world: We are as super and as great as ever before. We're doing things which no country can do in a similar capacity,' said Olga Krasnyak, an associate professor of international relations at the National Research University Higher School of Economics in Moscow. This mutually recognized opportunity for prestige led to tentative talks between the country's officials in 1970. From the get-go, it was clear that the mission faced immense diplomatic, technical, and cultural obstacles. There was no smooth glide path to launch. 'How do we communicate with people who speak entirely different languages, and who think differently about engineering and problem-solving?' Brian C. Odom, NASA's chief historian, said. 'On paper, it seems easy. You launch, we launch, we come together, we shake hands, we go our separate ways. But making that happen, where you don't have five people dying in orbit, is incredibly difficult.' The sudden switch from enemies to partners, at least in this limited case, caused whiplash for the public and politicians alike (a scenario that was dramatized in the Apple TV alternative history series 'For All Mankind'). Zbigniew Brzezinski, who later served as Jimmy Carter's national security adviser, criticized the Nixon and Ford administrations for the mission, calling it a 'technological giveaway.' Soviet space officials, who had long worked in secrecy, had to overcome wariness about loosening the flow of information to an adversary. The country's diplomats had to ensure that plans could be discussed without divulging anything sensitive to national security. Both sides were suspicious of the safety of the other's flagship spacecraft. The three astronauts selected for Apollo 1 perished in a fire during a rehearsal in 1967, while the three cosmonauts of Soyuz 11 died in space in 1971 when their cabin depressurized. Snipes about the superiority of one side's spacecraft over the other rankled insiders of the mission. American astronauts were used to a much more hands-on guidance system with Apollo, whereas Soyuz was largely automatic and controlled from the ground. The vehicles even used different atmospheres in their interiors. Soyuz simulates the familiar conditions of Earth, with a nitrogen-oxygen air mixture and a pressure equivalent to our planet at sea level. Apollo, in contrast, used a pure oxygen atmosphere at a much lower pressure. This discrepancy was solved by the development of a docking module with airtight hatches at each end. Once the module connected the two craft, crew members from one vehicle could enter, ensuring that both hatches were closed while it pressurized to match conditions of the other side. When that process was complete, the hatch to the other vehicle could be opened, allowing crews to safely enter without risking 'the bends,' a condition caused by rapid depressurization. For this particular mission, the Soyuz was kept at a lower pressure than normal to ease transitions between vehicles. The docking module was also purposefully designed to be androgynous to ensure that neither spacecraft was perceived as 'female,' or passive. As the mission planners navigated these headaches, a deep and abiding friendship flourished between the astronauts and cosmonauts. The Apollo side, headed by Stafford, also included Donald 'Deke' Slayton and Vance Brand. Leonov flew on the Soyuz side with Valery Kubasov. The crews learned each other's languages, though Leonov jokingly called Stafford's drawling pronunciation 'Oklahomski.' They trained together at NASA Johnson Space Center in Houston and Star City, the Russian space center outside Moscow. During these meetings, the space travelers hunted, drank and partied together. They shared steam baths and got into snowball fights. The two commanders remained particularly close for the rest of their lives: Leonov helped Stafford adopt two children from Russia, and Stafford gave a eulogy in Russian (or, rather, Oklahomski) at Leonov's funeral in 2019. The crews were 'setting an example, by being friendly and demonstrating cooperation,' said Brand, the last living member of the mission, in a 2000 interview with Rebecca Wright of NASA's Johnson Space Center Oral History Project. 'We actually came to have a very close relationship with the Soviet crew,' he added. Strawberry Juice and Borscht Against all odds, the crews finally reached their launch pads during the summer of 1975. On July 15, the Soyuz crew blasted off from Baikonur Cosmodrome in Kazakhstan, followed by the Apollo crew, which launched about seven hours later from Kennedy Space Center in Florida. The lead-up to docking was relatively smooth, though the Apollo crew discovered a 'super Florida mosquito' had stowed away with them, and Stafford joked that a juice spill had turned the Apollo into a 'strawberry-colored spacecraft.' The spaceships successfully docked at 12:12 p.m. Eastern time, July 17, high above the Atlantic Ocean. Hours later, the historic handshake was broadcast live to millions of viewers. The mission even inspired a cocktail called the Link Up, with equal parts Southern Comfort and vodka mixed with lime and ice, served at London's Savoy Hotel. The crew spent the next two days exchanging gifts, dining together (including borscht toasts), listening to music, and conducting experiments. The ships parted ways on July 19. After all the mutual worries about spacecraft safety, it was Apollo that ended up experiencing a serious incident, as toxic fumes filled the capsule during reentry. The brand lost consciousness, and the crew was hospitalized after splashdown. Despite this frightening conclusion of the mission, the astronauts quickly recovered and the mission was hailed as a diplomatic and technical success. 'A Little Bit Messy' A second Apollo-Soyuz mission was planned, but it never panned out. U.S.-Soviet tensions rose again during the late 1970s and into the 1980s. The countries did not directly team up again for years. However, both superpowers fostered new collaborations with their allies. During the 1980s, NASA space shuttle crews included Canadian, European, and Japanese astronauts, while the Soviet Union launched cosmonauts who came from Cuba, Poland, Vietnam, Afghanistan, and other countries. After the collapse of the Soviet Union, Americans and Russians again joined forces in space, first aboard the Mir space station in the early 1990s. The American-Russian partnership is now the backbone of the ISS, which has remained continuously inhabited since the year 2000. That outpost is in its twilight years. Russia is discussing building its own separate successor space station, and the U.S. is seeding commercial outposts in orbit — efforts that can make Apollo-Soyuz seem like a distant memory. But Krasnyak, the Russian international relations expert, said that the legacy of this mission, and cooperative space exploration in general, remains important to Russians 50 years later. Whether the U.S. and Russia partner on future human spaceflights or not, she noted that the two powers continue to be world leaders shaping international deliberations on space. Siddiqi, the historian of Russian spaceflight, views the 1975 U.S.-Soviet mission as a forerunner for the complex international partnerships that characterize modern spaceflight, even if it's in a 'roundabout way.' 'It was a little bit messy, but the road leads back to Apollo-Soyuz,' he said. 'Other historians would see it differently, as a kind of rupture or as a one-off, but I see a lot of continuities.' Odom, NASA's chief historian, does not see Apollo-Soyuz as a direct progenitor of the ISS, or of other subsequent space collaborations. From his perspective, the mission's legacy is grounded more in the context of a time when two feuding powers extended an olive branch into orbit, with repercussions for how their citizens viewed each other back on Earth. 'The people who were involved come away from it thinking about what cooperation really might mean,' Odom said. 'If we can cooperate with the Soviet Union in this way, we can cooperate with anyone.' The direct communication and interpersonal relationships were a powerful spinoff from the mission, Odom added. 'The thing that they come away with is that 'oh, you're human beings just like us,' he said. 'You're not the monsters that we imagined or feared that you would be. You're just people trying to do a job and go about your daily life.' This article originally appeared in

Fiona the Pregnant Sea Reptile's Fossil Hints at the Birth of a New Ocean
About 131 million years ago, a pregnant ichthyosaur — a dolphin-like reptile of the dinosaur era — swam in seas that are now part of southern Chile. And then she died. An accomplice in the killing: the breakup of the southern supercontinent of Gondwanaland. South America, once unified with Africa and Antarctica, pulled away, and a new ocean basin called the Roca Verdes opened up. 'One of the hypotheses is that this is actually the opening of the early South Atlantic Ocean,' said Matthew Malkowski, a professor of geological sciences in Texas. The geological forces that pulled apart the continents also ruptured the Earth's crust, causing volcanoes and earthquakes, and those earthquakes sometimes set off massive underwater landslides. One day in the early Cretaceous period, one of those landslides collapsed down a submarine canyon in Roca Verdes, generating turbulent flows of sediment. 'Probably these landslides might have trapped the ichthyosaurs and threw them to the bottom of the canyon and covered them with sediment,' said Judith Pardo-Pérez, an associate professor in Chile. — KENNETH CHANG / NYT
