Earth’s oceans, covering over 70% of the planet, remain largely unexplored due to the limitations of traditional mapping methods. Ship-based sonar, though precise, is slow and costly, leaving vast areas of the seafloor unmapped. This gap in knowledge restricts understanding of tectonic processes, underwater ecosystems, and marine biodiversity. However, the Surface Water and Ocean Topography …
The Greenland ice sheet, one of the largest ice masses on Earth, is melting at an unprecedented rate, driving global sea level rise and disrupting weather patterns worldwide. Understanding its changes is vital, but precise measurements of its volume and shape have historically been difficult. The European Space Agency’s CryoSat and NASA’s ICESat-2 have transformed …

Recent genetic research has dramatically reshaped our understanding of human history, revealing that the survival and global spread of modern humans were not as straightforward as previously believed. Central to this narrative is the concept of Neanderthal interbreeding, which played a pivotal role in our ancestors’ ability to thrive outside Africa. This genetic exchange has …

Over the past three decades, an expanse of land substantially larger than India has transformed from humid to dryland, with drylands now constituting 40% of the Earth’s surface, excluding Antarctica. This shift towards global aridification has had profound implications, with the UN Science Policy Interface reporting that three-quarters of the world’s land experienced drier conditions …
Volcanoes are nature’s dramatic sculptors, known for their power to alter landscapes and ecosystems profoundly. Among the numerous volcanic events, the eruption of Mount Tambora in 1815 stands unparalleled in its global impact. This eruption, the most powerful in recorded history, drastically reshaped Mount Tambora itself, reducing its height by over 4,000 feet and creating …

Caltech researchers have unveiled a groundbreaking method to probe the deep structure of the Earth, particularly at the Mohorovičić discontinuity, known as the Moho. This method employs the advanced technology of distributed acoustic sensing (DAS), akin to performing an ultrasound on the Earth. Their study, detailed in Science Advances, capitalizes on how seismic waves from …

Last year set a grim record as the hottest year ever documented, with unprecedented ocean temperatures and accelerated glacier melts, prompting a scramble among scientists to determine the underlying causes. While the primary suspects included the usual culprits—greenhouse gas emissions from fossil fuels and the natural El Niño phenomenon—these factors alone could not fully account …
