Ms Gali, who was visiting from India's Andhra Pradesh state, was reportedly heading towards a nearby temple with her family when she was swallowed by the 8m (26ft) deep sinkhole on the street of Jalan Masjid India. Excavators were deployed shortly after the incident to dig up the area around the sinkhole, while rescuers used sniffer dogs and crawler cameras - robotic cameras used to inspect pipes - to get a better sense of what was happening underground. They have also tried to break apart hardened debris using high-pressure water jets, iron hooks and rope. On Tuesday, officials wheeled a ground-penetrating radar device onto the site, to help them pinpoint changes in material density underground. The next day, a second sinkhole appeared just 50m from the first one.

A massive sinkhole opened up at a soccer field in Alton, Illinois, on Wednesday. A 100-foot-wide sinkhole opened beneath a soccer field in Illinois on Wednesday as a result of a collapse at a nearby underground mine, officials said. The sinkhole formed at around 10 a.m. at Gordon Moore Park in Alton. Surveillance video from the City of Alton shows the moment the sinkhole opens and swallows a light pole on the field in a cloud of dust. Drone video shows the aftermath of the crater in the center of the field.

Scientists used torpedo-shaped robots to map the Arctic seafloor with sonar, revealing massive sinkholes of thawed permafrost. This story was originally published by Wired and is reproduced here as part of the Climate Desk collaboration. Around 20,000 years ago, the world was so frigid that massive glaciers sucked up enough water to lower sea levels by 400 feet. As the sea pulled back, newly exposed land froze to form permafrost, a mixture of earth and ice that today sprawls across the far north. But as the world warmed into the climate we enjoy today (for the time being), sea levels rose again, submerging the coastal edges of that permafrost, which remain frozen below the water. It's a huge, hidden climate variable that scientists are racing to understand.

A team of researchers have mapped the mysterious Dragon's Breath Cave in Namibia, one of the world's largest underground lakes located below the Kalahari Desert. The lake's size and depth had been a problem for human divers who attempted to document it in the past. These weren't problems for the AI-powered underwater drone, nicknamed SUNFISH, which the team from Stone Aerospace, a company in Austin, Texas, used to create the first fully realized 3D map of the mysterious cave. A team of engineers from Austin traveled to Namibia to try and map one of the world's largest underground lakes, the Dragon's Breath Cave, with an AI-powered drone SUNFISH looks like a small enclosed canoe and is powered by a set of small propellers. It uses a sonar mapping system to create a 3D image of its surroundings, which an onboard AI system then uses to make decisions about where to go next.

Car manufacturers know: There's a huge amount of interest in AI-driven cars. Many people would love to automate the task of driving, because they find it tedious or at times impossible. A competent AI driver would have lightning-fast reflexes, would never weave or drift in its lane, and would never drive aggressively. An AI driver would never get tired and could take the wheel for endless hours while we humans nap or party. While AI does need huge volumes of data to program and guide it, that shouldn't be a problem.

It sounds like the plot of a James Bond movie: A charismatic billionaire wants to build a network of high tech tunnels beneath America's cities and slay an enemy in the process. In addition to building electric vehicles, launching rockets, and colonizing Mars, Musk wants to reinvent tunneling and destroy soul-sucking traffic. Just how Musk's latest venture, the wonderfully named Boring Company, will do that remains rather opaque, perhaps even to Musk himself. "We're just going to figure out what it takes to improve tunneling speed by, I think, somewhere between 500 and 1,000 percent," he said in February, with the nonchalance of someone ordering a latte. "We have no idea what we're doing--I want to be clear about that."

Fujitsu EMEIA CTO Dr Joseph Reger looks at how Artificial Intelligence is proliferating at an uncontrollable pace, arguing that businesses can no longer ignore the impact it is having. Discussions around Artificial Intelligence (AI) have proliferated and will continue to over the next year. Businesses are beginning to see its value in a wide range of sectors, while a different report is released every day that instils a fear that AI will replace workers' jobs. Simply put there is no hiding the explosion of AI and its applications; in the UK, Durham police have begun trialling a system that will classify suspects as low, medium or high risk and help officers review their sentence. As AI, automation and machine learning push the boundaries in almost every single industry, businesses will have to embrace the technology and understand that it is a force for good.

It's a hot late-spring Friday on a cactus-studded cattle ranch in Mexico, and nothing is happening. Nothing, in fact, has been happening for going on a week now, and it's starting to get tedious. Ordinarily, the group of scientists, engineers, and students who have gathered here might have enjoyed a respite from their otherwise crazy schedules. But they didn't come here to catch up on their reading, play the guitar, or take long, leisurely walks. They came here to work. Their goal is to field-test one of the most intelligent and agile underwater robots ever crafted, a possible predecessor of a machine that might someday swim the vast, ice-crusted ocean of Jupiter's mysterious moon Europa. Called DEPTHX, for DEep Phreatic THermal eXplorer, the 1.3-metric-ton machine can maneuver freely, draw detailed, three-dimensional maps of its watery surroundings, and collect solid and liquid biological samples as it senses changing conditions in its environment. Most important, it does all that without any guidance from human operators. Such autonomy would be essential if the robot ever does swim on Europa--which may be warm enough, thanks to geothermal activity, to have given rise to some sort of life. Human control of a robot sub that far away isn't an option: radio waves don't effectively penetrate water. Even if they did, a round-trip radio signal would take 2 hours or more, making remote control unlikely. But today, on this sweltering retreat near the Gulf Coast of Mexico, with cicadas buzzing and a hazy sun beating down, Europa seems a long way off.
