Hold the syrup: Weirdly perfect 'pancakes' on Venus may prove the planet is buckling
When you buy through links on our articles, Future and its syndication partners may earn a commission. Scientists may have finally cracked the recipe behind Venus' giant pancakes. Venus is famous for its "pancake domes" — steep-sided volcanoes that rise from the planet's surface like circular welts. A study now suggests that these unusual dome-shaped structures are at least partly sculpted by the planet's upper crust, which seems more flexible in certain regions. Volcanoes are common across Venus, with more than 1,600 large volcanoes or volcanic features discovered so far. One of the more intriguing types are the so-called pancake domes, disk-shaped structures that stretch over tens of miles but are only half a mile in height, like a flattened version of Hawaii's Mauna Loa. Exactly how these volcanoes form — and what they're made of — is still a mystery. One idea is that they develop from super-sticky, slow-flowing lava that moves under the force of its own weight (the technical term for this phenomenon is a viscous gravity current). Eventually, the lava stops moving and solidifies, forming the pancake domes. But does the domes' formation depend only on the type of lava? Probably not, Madison Borrelli, a postdoctoral researcher at the Georgia Institute of Technology and first author of the new study, told Live Science by email. One factor that many previous studies hadn't considered was the bendiness', or the flexure, of Venus' upper crust. It turns out that Venus' surface — and Earth's — behaves, in certain areas, like an orange's skin: under a sufficiently heavy load, the surfaces dimple. If such dimpling accompanied the pancake domes' formation, it would leave certain tell-tale signs, like a bulge surrounding the dome, where the crust buckled upwards. Indeed, a 2021 study found such flexural signatures surrounding one-fifth of a sample of Venusian pancake domes. Related: Venus may be geologically 'alive' after all, reanalysis of 30-year-old NASA data reveals To determine how a bendy crust could affect the formation of a pancake dome, Borrelli and her colleagues at universities in France and the U.S. focused on the only dome for which they had high resolution data: the Narina Tholus, an 88.5-mile-wide (55 kilometers) dome located on the circumference of the Aramaiti Corona, one of the many giant oval structures that pockmark Venus' surface. The new study, published May 10 in the Journal of Geophysical Research: Planets, used topographical data collected by NASA's radar-wielding Magellan mission in the 1990s, the researchers created a virtual model of the Narina Tholus dome. They then simulated viscous gravity currents of lavas of different densities atop both a flexible upper crust and a rigid lithosphere, and compared the results to the virtual dome. The study's results showed that domes created on a bendy crust looked far more like the virtual pancake dome than those that formed on the rigid lithosphere. In particular, the flexible crust's domes had flat tops and very steep sides, characteristic of the pancake domes. This stems from the fact that the bulge around the dome prevents the lava from flowing further, causing it to accumulate, the researchers said. The bendy lithosphere's domes also had flexural signatures similar to that of Narina Tholus. However, the dimpling of the lithosphere couldn't alone explain the domes' features — the lava's density mattered too. Although low-density lavas produced domes with the right sort of shape, they created smaller crustal bulges than those found near the real-life pancake dome. Only lavas denser than 0.0867 lbs per cubic inch (2,400 kg/m3) — or over twice the density of room temperature water — produced both the correct dome shapes and flexural signatures. These high-density lavas were more than a trillion times as viscous as ketchup at room temperature and settled down to form the domes over hundreds of thousands of Earth-years. Nonetheless, the study's main drawback is that it used data from just the Narina Tholus dome. Borrelli hopes that upcoming missions to Venus — like NASA's VERITAS program — will provide higher resolution topography of the planet's surface, allowing the researchers to test their model with more data.

While most Venusian volcanoes appear to spew Mauna Loa-like basaltic lava, the researchers couldn't rule out rhyolitic and andesitic lavas, similar to those that spout from Mount St. Helens. Borelli said that finding diverse lava types on Venus would be interesting. "This can tell us about the planet's tectonic history, magmatic processes, and even the potential past presence of water."

Tories Narrowly Win Ontario Riding After Recount, Results Upcoming in Newfoundland Recount
A ballot recount has confirmed that Conservative candidate Kathy Borrelli beat the Liberal incumbent Irek Kusmierczyk in an Ontario riding, while results in another Newfoundland recount are expected today. In the riding of Windsor-Tecumseh-Lakeshore, Borrelli initially beat Kusmierczyk by 233 votes on election night on April 28. However, an initial Elections Canada validation count reduced Borrelli's lead to 77, which was seven votes short of triggering an automatic recount. Kusmierczyk, who has been the MP for the riding since 2019, told reporters on May 9 his team of volunteers had identified some ballots that had been mistakenly rejected. They presented their evidence to Justice Ross Macfarlane to request a recount, which he accepted. A , which is conducted by a judge, must take place if the margin of victory for a candidate is less than 0.1 percent of the valid votes cast.

Newfoundland and Labrador Riding It is also expected that the results for another recount in the Newfoundland and Labrador riding of Terra Nova-The Peninsulas will be released later in the day. The initial vote tally saw Liberal candidate Anthony Germain win the riding with just 12 votes more than Conservative candidate Jonathan Rowe, which triggered a judicial recount. When the announcement was made that Germain had triumphed over Rowe by a mere 12 votes on April 29, the closest victory margin in any riding race across Canada at that time. This record has since been surpassed by the Quebec riding of Terrebonne, where the Liberals secured victory by a single vote after a judicial recount. The Bloc Québécois it will challenge the results in the riding following reports that a Terrebonne resident had mailed in a vote supporting the Bloc weeks ahead of the April 28 election, but the ballot was returned to the voter on May 2 because Elections Canada had put the wrong return address on the envelope. Elections Canada previously told the Epoch Times that five mail-in ballots that were received late at the local office in Quebec's Terrebonne riding were not able to be counted. Each of the five late ballots contained a postal code error. Sixteen other ballots were not sent to the local office and were instead returned to the elector because of an addressing error, Elections Canada said. Nine remaining electors who had originally requested a mail-in ballot opted to cast their votes in person instead.

Newfoundland Riding Flips to Conservatives After Recount
The Newfoundland and Labrador riding of Terra Nova—The Peninsulas has flipped to the Conservatives following a judicial recount, giving the party a third seat in the province. A recount in the riding completed on May 23 found that Conservative Jonathan Rowe defeated Liberal Anthony Germain by 12 votes. The The results have brought the Liberal Party's seat count down to 169, which is three short of a majority, while the Conservatives have 144 seats, the Bloc Québécois has 22, the NDP has seven, and the Green Party has one. The initial tally on election night had Germain ahead by 12 votes, with the margin of victory being narrow enough to trigger an automatic judicial recount. These happen when the margin of victory for a candidate is less than 0.1 percent of the valid votes cast. In a statement on social media, 'I'm so proud of what our campaign accomplished, I'm thankful to all who believed in our positive message, and I'm energized to keep working to make our community a better place,' he said.

Montreal family searches for mystery hero who saved 87-year-old man's life
A Montreal family is appealing to the public to help identify the stranger who performed life-saving CPR on their elderly relative after he collapsed during an afternoon walk. Sabato Borrelli, 87, suffered a cardiac arrest last Thursday while walking alone in his Ahuntsic–Cartierville neighbourhood. Paramedics who arrived at the scene told the family a passerby performed CPR on Borrelli before they took over. The stranger's intervention likely saved his life. 'He wouldn't have survived if that person hadn't acted so quickly,' said Lucia Orfeo in an interview with The Gazette. She is Borrelli's former daughter-in-law and remains close with the family. 'They gave us more time with him, and we're so grateful. We just want to say thank you,' she added. The family says Borrelli had already returned home from his usual morning walk and lunch when he stepped out again for a second stroll, a near-daily routine for the retired construction worker, who Orfeo describes as active, social and independent. When Borrelli arrived at the hospital, he suffered a second cardiac arrest and had to be revived again by medical staff. But despite initial fears, he regained consciousness on Sunday. Though still recovering in hospital, his condition has improved, Orfeo said, and he is growing stronger each day. 'He wants to go home. He says he has work to do,' Orfeo said. 'He's someone who still makes his own wine, his own tomato sauce, and tends to his garden and the local bocce field. He's not your typical 87-year-old.' The incident has been especially emotional for Orfeo, whose daughter — Borrelli's granddaughter — died two and a half years ago after suffering a sudden brain haemorrhage and cardiac arrest. She was unable to be revived. 'He was on a ventilator, very much like my daughter, in the same hospital, the same ICU,' she said. 'It felt like a kind of full circle.' The family has tried to obtain information about the Good Samaritan from hospital staff and emergency services, but privacy protocols prevent officials from releasing identifying details. Orfeo posted an appeal on a local Facebook group, Montrealers Helping Montrealers, which has since attracted media attention and supportive comments, yet the stranger remains unknown. 'It's their right to remain anonymous, and we'd respect that,' Orfeo said. 'But if they're reading this, I just want them to know what they did, it meant everything to us.' She added the incident has reinforced her belief in the importance of learning CPR. 'Not everyone is in a position to help like that, but this person didn't hesitate. They saved a life. And we'll never forget it.' Borrelli remains in hospital, but is expected to make a full recovery.
