ESA-SSTL Twin HydroGNSS Satellites Return Water Cycle Data During Commissioning
London, UK (SPX) ) May 01, 2026
Just three months after launch, the twin HydroGNSS satellites built by Surrey Satellite Technology Ltd for the European Space Agency are producing early science measurements, detecting water-linked surface conditions across Earth even while still in their commissioning phase.

The NISAR satellite has produced detailed radar maps of ground subsidence beneath Mexico City, showing parts of the metropolitan area sinking by more than half an inch - more than 2 centimeters - per month, driven largely by decades of groundwater extraction from the aquifer underlying the city.
The measurements, based on preliminary data collected between October 2025 and January 2026 dur 
A study led by the University of Oxford and ETH Zurich has identified a fundamental weakness in current climate models: their inability to accurately simulate the large-scale wind and circulation patterns that determine where rain falls. The finding helps explain why regional rainfall forecasts remain persistently uncertain even as global warming trends become clearer, and why projections of fut 
An international team of earth scientists led by Utrecht University professor Douwe van Hinsbergen has launched a publicly accessible online tool that lets users determine what latitude any location on Earth occupied at any point in the past 320 million years, back to the era of the supercontinent Pangaea.
The tool, hosted at Paleolatitude.org, is built on the Utrecht Paleogeography Model, 
Researchers at UCLA have developed a method to construct programmable artificial organelles inside living cells using RNA as both the structural material and the assembly blueprint, an advance they say opens new possibilities in nanomedicine and cell engineering.
The work, published April 29 in Nature Nanotechnology, centers on membrane-less organelles known as biomolecular condensates - d 
Policies that have driven significant reductions in deforestation across the Brazilian Amazon over the past two decades have largely failed to address forest degradation - a slower, less visible, and potentially more dangerous form of forest destruction - according to a new study led by the University of Cambridge.
The findings are published in the Proceedings of the National Academy of Sc 
Between 50,000 and 10,000 years ago, many of the world's largest mammals vanished from the Earth. Creatures such as saber-toothed cats with seven-inch fangs, elephant-sized ground sloths, woolly mammoths with tusks growing longer than 12 feet, and a three-ton wombat the size of a car all disappeared after roaming the planet for millions of years. A new study now reveals how that wave of extincti 
The ancient city of Napata, situated in what is now northern Sudan, served as a major urban and cultural hub of the Kushite empire for nearly a millennium. New research from University of Michigan archaeologists and earth scientists reveals that the city's remarkable longevity was rooted not only in politics or culture, but in geology - specifically, the behavior of the Nile River over thousands 
An international study led by Adelaide University has found that bowhead whale populations are recovering only in stocks where large areas of hazardous sea ice once limited devastating hunting centuries ago.
The research team analysed historical logbooks from more than 700 whaling voyages, reconstructing daily positions and hunting successes across the Arctic.
'We found that whaling 
Dolphins are renowned for their speed and agility in water, yet the precise fluid dynamics that make them such efficient swimmers have long remained elusive. Researchers at The University of Osaka have now used large-scale supercomputer simulations to identify the dominant physical mechanism: powerful large-scale vortex rings generated by the dolphin's oscillating tail.

When Mauna Loa erupted in November 2022, the largest lava flow advanced directly toward Daniel K. Inouye State Highway 200, known as Saddle Road, a critical transportation corridor connecting communities on opposite sides of Hawaii's Big Island. Scientists at the time had no reliable means of predicting whether the flow would reach and block the road or stop short. New research from the Universi 
Researchers at Kyoto University have identified a distinct seismic signal - a negative phase in near-fault waveforms - that marks the abrupt arrest of large strike-slip earthquakes and carries significant implications for seismic hazard assessment near active fault systems. The findings are published in Science.

New research from Hokkaido University has found that the earliest known octopuses were not small, cryptic animals hiding in reef crevices but enormous apex predators that dominated Cretaceous marine ecosystems alongside large vertebrates. The study, published in Science on 23 April 2026, pushes the fossil record of octopuses back by approximately five million years to around 100 million years ag 
Researchers at UNSW Sydney have trained a neural network to detect blue whale songs in decades-long acoustic recordings using just a single example call, achieving an accuracy of 99.4 percent across real-world datasets spanning multiple ocean basins. The study, led by PhD candidate Ben Jancovich, is published in Scientific Reports.

A new satellite-based analytical framework developed by researchers from Mississippi State University and collaborating institutions can accurately estimate crop sowing and emergence dates at the field scale, offering improved tools for agricultural management, yield forecasting, and large-scale monitoring.
