For the first time ever, a CCTV camera in Myanmar captured real-time footage of a supershear strike-slip earthquake moving at 3.7 miles per second. According to seismologists at Japan's Kyoto University, the analysis has "led to new findings based on real-time visual evidence of tectonic motion," reports Popular Science. From the report: The magnitude 7.7 event took place on March 28 along the Sagaing Fault with an epicenter near Myanmar's second-largest city, Mandalay. Although the initial rupture process lasted barely 80 seconds, it and numerous aftershocks were ultimately responsible for 5,456 confirmed deaths and over 11,000 injuries. Later evaluations indicated the quake was the second deadliest in modern history, as well as the most powerful to hit Myanmar in over a century. According to a separate group's paper published in the same journal, the southern portion of the rupture occurred at an astonishing 3.7 miles per second -- fast enough to qualify as "supershear velocity."
Amid the catastrophe, an outdoor CCTV camera about 74.5 miles south of the epicenter recorded a visceral illustration of its power. Over just a few moments, what at first looks like a single chunk of the ground appears to suddenly divide and horizontally shift past one another in opposite directions. Completely by accident, the camera recorded a direct look of a strike-slip fault, something previously analyzed by remote seismic instruments. To researchers at Kyoto University, the clip wasn't just a jaw-dropping scene -- it was an opportunity to study a strike-slip fault using visual data. You can watch the footage on YouTube.

Conspiracy theorists drastically overestimate how many people share their beliefs, according to a study published in the Personality and Social Psychology Bulletin. Researchers conducted eight studies involving over 4,000 US adults and found that while participants believed conspiracy claims just 12% of the time, believers thought they were in the majority 93% of the time.
The study examined beliefs about claims such as the Apollo Moon landings being faked and Princess Diana's death not being an accident. In one example, 8% of participants believed the Sandy Hook shooting was a false flag operation, but that group estimated 61% of people agreed with them. "It might be one of the biggest false consensus effects that's been observed," said co-author Gordon Pennycook, a psychologist at Cornell University. The findings suggest overconfidence serves as a primary driver of conspiracy beliefs.

Government funding for a program that hunts for threats on America's critical infrastructure networks expired on Sunday, preventing Lawrence Livermore National Laboratory from analyzing activity that could indicate a cyberattack, the program director told Congress on Tuesday. From a report: Nate Gleason leads a team at Lawrence Livermore National Laboratory (LLNL) focused on nation-state threats against critical infrastructure, and this includes the CyberSentry Program.
It's a public-private partnership, managed by CISA, that looks for malicious activity on IT and operational technology (OT) networks in America's energy, water, healthcare, and other critical facilities. This includes threats along the lines of China's Volt Typhoon and Salt Typhoon intrusions -- network activity that may look like, or even start as, espionage, but ultimately enables the digital invaders to backdoor critical orgs and deploy cyber weapons to aid in a kinetic war.

An anonymous reader quotes a report from NBC News: Using brain scans from a very large database, British researchers determined that during the pandemic years of 2021 and 2022, people's brains showed signs of aging, including shrinkage, according to the report published in Nature Communications. People who got infected with the virus also showed deficits in certain cognitive abilities, such as processing speed and mental flexibility. The aging effect "was most pronounced in males and those from more socioeconomically deprived backgrounds," said the study's first author, Ali-Reza Mohammadi-Nejad, a neuroimaging researcher at the University of Nottingham, via email. "It highlights that brain health is not shaped solely by illness, but also by broader life experiences."
Overall, the researchers found a 5.5-month acceleration in aging associated with the pandemic. On average, the difference in brain aging between men and women was small, about 2.5 months. "We don't yet know exactly why, but this fits with other research suggesting that men may be more affected by certain types of stress or health challenges," Mohammadi-Nejad said. [...] The study wasn't designed to pinpoint specific causes. "But it is likely that the cumulative experience of the pandemic -- including psychological stress, social isolation, disruptions in daily life, reduced activity and wellness -- contributed to the observed changes," Mohammadi-Nejad said. "In this sense, the pandemic period itself appears to have left a mark on our brains, even in the absence of infection." "The most intriguing finding in this study is that only those who were infected with SARS-CoV-2 showed any cognitive deficits, despite structural aging," said Jacqueline Becker, a clinical neuropsychologist and assistant professor of medicine at the Icahn School of Medicine at Mount Sinai. "This speaks a little to the effects of the virus itself."
The study may shed light on conditions like long Covid and chronic fatigue, though it's still unclear whether the observed brain changes in uninfected individuals will lead to noticeable effects on brain function.
