Widespread UPI Outage Disrupts Digital Payments Across India

A significant outage struck India’s digital payment infrastructure on Saturday morning, bringing Unified Payments Interface (UPI) services to a standstill across multiple platforms. Popular payment apps such as PhonePe, Google Pay, Paytm, and BHIM were hit by the disruption, leaving thousands of users unable to complete transactions. The impact wasn’t limited to digital wallets—major banks like HDFC Bank, SBI, Kotak Mahindra, and others also experienced service interruptions. This marks the fourth UPI outage within a month, raising concerns over the stability of the nation’s most widely used payment system.

Reports of the outage began to surface shortly after 11:26 AM IST, with a spike in complaints observed around 1:02 PM, according to DownDetector. The disruption affected a wide range of services, from peer-to-peer transfers to merchant payments, leaving both customers and businesses scrambling for alternatives. With UPI now deeply embedded in India’s financial ecosystem, even short-term service outages have a ripple effect, disrupting everyday transactions and causing widespread inconvenience.

Responding to the issue, the National Payments Corporation of India (NPCI) took to social media to acknowledge the problem. In a post on its official X (formerly Twitter) account, NPCI stated: “NPCI is currently facing intermittent technical issues, leading to partial UPI transaction declines. We are working to resolve the issue and will keep you updated. We regret the inconvenience caused.” The organization has not yet provided an estimated time for resolution.

This latest outage once again highlights the need for greater resilience and redundancy in digital payment infrastructure. As more Indians shift to cashless transactions, the reliability of services like UPI becomes critical.

Scientists Pin Down the Elusive Length of a Day on Uranus

Uranus’ Day Finally Measured: A 17-Hour Spin on Its Side

After decades of uncertainty, scientists have finally nailed down how long a day lasts on Uranus, thanks to a detailed analysis of data collected over ten years by the Hubble Space Telescope. According to the latest findings, the ice giant takes 17 hours, 14 minutes, and 52 seconds to complete a full rotation. That’s just 28 seconds longer than the earlier estimate provided by NASA’s Voyager 2 mission in the 1980s. The breakthrough came from tracking subtle signals—specifically, magnetic field variations and radio emissions tied to the planet’s auroras.

The new study, led by Laurent Lamy of the Paris Observatory, used long-term aurora observations to reveal the exact location of Uranus’ magnetic poles. These poles helped researchers determine the planet’s rotation period more accurately than ever before. While Uranus takes roughly 84 Earth years to complete one orbit around the Sun, its daily spin has remained elusive due to its chaotic atmospheric conditions. On a planet where high-speed winds and tilted axes complicate surface measurements, auroras offer a more reliable method for timing the rotation.

Unlike Earth or Mars, Uranus presents unique challenges for scientists. Its unusual 98-degree axial tilt means it essentially spins on its side, making traditional rotational tracking methods less effective. Back in 1986, Voyager 2 observed that the planet’s magnetic field was offset by 59 degrees from the planet’s axis, which added further complexity to measuring a day. The new measurements not only refine Voyager’s findings but also provide crucial context for understanding Uranus’ strange orientation and inner workings.

These updated figures are more than just trivia—they’re essential for future exploration. As space agencies consider missions to the outer planets, having an accurate understanding of Uranus’ spin rate and magnetic field behavior can help scientists design better instruments and flight plans. With its sideways spin and extreme seasons, Uranus continues to be one of the most mysterious planets in our solar system—but bit by bit, its secrets are being revealed.

Ancient Farallon Slab Tugs at Midwest Crust, Triggering Regional Thinning

Ancient Slab Beneath U.S. Heartland Linked to Crustal Thinning Across the Region

A massive underground structure deep beneath the central United States is quietly reshaping the continent from below. Scientists have discovered that a buried remnant of ancient crust is dragging surface materials downward, drawing rock from a wide area into a funnel-like zone beneath the Midwest. This movement is believed to be causing parts of Earth’s crust in the region to thin significantly—a phenomenon that surprisingly stretches beyond the immediate area affected.

At the heart of the discovery is the Farallon slab, a long-subducted tectonic plate that now rests roughly 660 kilometers below the surface. Published in Nature Geoscience, the new study connects this ancient remnant to what geologists call “cratonic thinning.” Cratons are some of the oldest and most stable parts of Earth’s crust, typically untouched by tectonic shifts. But the presence of the Farallon slab seems to be disturbing this stability, pulling at the base of the continent and causing unexpected changes to the deep structure of North America.

The research was led by Junlin Hua, who conducted the seismic mapping as a postdoctoral researcher at The University of Texas at Austin. Now a professor in China, Hua described the widespread crustal thinning as an eye-opening find. According to him, the study presents a novel explanation for long-observed changes beneath the region. It’s a departure from conventional thinking, and the research team believes it provides a clearer view of how deep-Earth processes can influence surface geology over vast distances.

To explore these hidden movements, scientists relied on a powerful seismic imaging technique called full-waveform inversion. This method allowed researchers to capture detailed 3D images of Earth’s interior, offering an unprecedented look at the interaction between the lower mantle and the overlying lithosphere. Thorsten Becker, chair of geophysics at UT Austin, noted that the imaging revealed a distinctive “dripping” pattern in the lithosphere—only present when the Farallon slab was included in computer models. When the slab was removed from simulations, the phenomenon vanished, reinforcing its role in reshaping the continent from below.
