An anonymous reader shares a report: On May 4, 2022, NASA’s InSight lander detected the largest quake yet recorded on Mars, one with a 4.7 magnitude — fairly modest by Earth standards but strong for our planetary neighbor. Given Mars lacks the geological process called plate tectonics that generates earthquakes on our planet, scientists suspected a meteorite impact had caused this marsquake. But a search for an impact crater came up empty, leading scientists to conclude that this quake was caused by tectonic activity — rumbling in the planet’s interior — and giving them a deeper understanding about what makes Mars shake, rattle and roll.

“We concluded that the largest marsquake seen by InSight was tectonic, not an impact. This is important as it shows the faults on Mars can host hefty marsquakes,” said planetary scientist Ben Fernando of the University of Oxford in England, lead author of the research published this week in the journal Geophysical Research Letters. “We really thought that this event might be an impact.” “This represents a significant step forward in our understanding of Martian seismic activity and takes us one step closer to better unraveling the planet’s tectonic processes,” added Imperial College London planetary scientist and study co-author Constantinos Charalambous, co-chair of InSight’s Geology Working Group.

NASA retired InSight in 2022 after four years of operations. In all, InSight’s seismometer instrument detected 1,319 marsquakes. Earth’s crust – its outermost layer – is divided into immense plates that continually shift, triggering quakes. The Martian crust is a single solid plate. But that does not mean all is quiet on the Martian front. “There are still faults that are active on Mars. The planet is still slowly shrinking and cooling, and there is still motion within the crust even though there are no active plate tectonic processes going on anymore. These faults can trigger quakes,” Fernando said.

The Five Eyes countries’ intelligence chiefs came together on Tuesday to accuse China of intellectual property theft and using artificial intelligence for hacking and spying against the nations, in a rare joint statement by the allies. From a report: The officials from the United States, Britain, Canada, Australia and New Zealand – known as the Five Eyes intelligence sharing network – made the comments following meetings with private companies in the U.S. innovation hub Silicon Valley. U.S. FBI Director Christopher Wray said the “unprecedented” joint call was meant to confront the “unprecedented threat” China poses to innovation across the world.

From quantum technology and robotics to biotechnology and artificial intelligence, China was stealing secrets in various sectors, the officials said. “China has long targeted businesses with a web of techniques all at once: cyber intrusions, human intelligence operations, seemingly innocuous corporate investments and transactions,” Wray said. “Every strand of that web had become more brazen, and more dangerous.” In response, Chinese government spokesman Liu Pengyu said the country was committed to intellectual property protection.

AI will likely lead to seismic changes to the workforce, eliminating many professions and requiring a societal rethink of how people spend their time, prominent tech leaders said Tuesday. From a report: Speaking at The Wall Street Journal’s Tech Live conference on Tuesday, OpenAI CEO Sam Altman said that the changes could hit some people in the economy more seriously than others, even if society as a whole improves. This will likely be a hard sell for the most affected people, he said. “We are really going to have to do something about this transition,” said Altman, who added that society will have to confront the speed at which the change happens. “People need to have agency, the ability to influence. We need to jointly be architects of the future.” Artificial intelligence is expected to transform the global economy by driving gains in both productivity and growth. But economists and tech entrepreneurs are divided on how quickly this shift could — and should — happen.

Earlier Tuesday, Vinod Khosla, a prominent venture capitalist whose firm was one of OpenAI’s earliest backers, laid out a stark timeline for AI’s transformation of work. Within 10 years AI will be able to “do 80% of 80% of all jobs that we know of today,” said Khosla, a tech investor and entrepreneur for more than 40 years. He pointed to many types of physicians and accountants as examples of professions that AI could largely supplant because these systems can more easily access a broad array of knowledge. Khosla likened the extent of the workforce changes to the disappearance of agricultural jobs in the U.S. in the 20th Century — a transition that took place over generations, not years.
