• Mega tsunamis in Greenland fjord confirmed as source of nine-day global seismic signal

    ByHarsh Vardhan

    A persistent, ultra-low frequency seismic vibration was detected worldwide in September 2023 and traced to Dickson Fjord, East Greenland, after two large landslides triggered tsunamis and a long-lasting seiche. For the first time, researchers directly observed this standing wave using NASA’s SWOT satellite mission, providing new insights into the connection between global seismic signals and surface water motion in remote coastal environments.

  • Hidden asteroids in Venus’ orbit pose impact risk to Earth

    ByHarsh Vardhan

    New research suggests we may be overlooking a population of asteroids quietly orbiting alongside Venus. Though rarely observed, these co-orbitals could drift into Earth-crossing paths and pose a real impact threat. New simulations highlight the gaps in current detection efforts and make a strong case for space-based surveys near Venus.

  • Experiment confirms electric power generation from Earth’s rotation

    ByHarsh Vardhan

    Researchers from Princeton University have experimentally demonstrated that Earth’s rotation through its magnetic field can generate electric power. The findings support a theoretical model that challenges long-standing assumptions about the impracticality of harvesting rotational energy from Earth’s magnetic field.

  • Most intense solar storm ever recorded struck Earth in 12 350 BC

    ByHarsh Vardhan

    A massive solar storm that struck Earth over 14 000 years ago has been identified as the strongest ever recorded. Traces of the event were discovered in ancient tree rings, revealing a sharp spike in radiocarbon levels in 12 350 BC. The finding extends the known limits of solar activity and provides a rare reference point for dating events in the Late Glacial period.

  • Solar flares trigger rhythmic changes in Earth’s skies

    ByHarsh Vardhan

    A new study shows that Earth’s upper atmosphere can pulse in near-perfect sync with subtle rhythms from the Sun. Researchers tracked minute-scale bursts from a powerful solar flare and found matching fluctuations in electron density overhead. The discovery reveals a direct, finely timed link between solar activity and conditions in Earth’s ionosphere.

  • Ground sinking affects 28 major U.S. cities

    ByHarsh Vardhan

    The ground beneath major U.S. cities is slowly sinking, according to new research that documents land subsidence in all 28 of the nation’s most populous urban areas. Driven primarily by groundwater extraction, the phenomenon poses a structural risk to homes, roads, and infrastructure in cities such as New York, Houston, and Chicago.

  • Natural disaster losses surpass USD 110 billion in Q1 2025, closing in on twice the 10-year average

    ByHarsh Vardhan

    Natural disaster-related losses in the first quarter of 2025 have surged to over USD 110 billion, a sharp increase from the decade-long average. While insurers absorbed a substantial portion of these damages, nearly half of the losses remain uninsured. With the US facing mounting risks from severe storms and wildfires, the protection gap remains a growing concern.

  • Antarctica sees ice gain after two decades of decline

    ByHarsh Vardhan

    Antarctica has shown a rare shift in behavior, gaining ice mass between 2021 and 2023 after years of steady decline. Using satellite gravimetry, researchers tracked this anomaly and linked it to unusual precipitation rather than long-term change. The findings offer insight into the continent’s sensitivity but little certainty about what comes next.

  • Unrest at dormant Uturuncu volcano driven by gas and fluid movement, not magma

    ByReet Kaur

    A new study published in PNAS provides the most detailed view to date of the dormant Uturuncu volcano in southwestern Bolivia, revealing that its long-standing ground deformation and seismic unrest are driven by the movement of hot fluids and gases, not by magma ascent. Researchers conclude there is no immediate eruption risk, but confirm that a deep magmatic system remains active beneath the surface.
