A major scientific breakthrough in ocean floor mapping has been achieved with new data from NASA’s Surface Water and Ocean Topography (SWOT) satellite, which revealed approximately 100,000 seamounts across the globe—more than doubling previous estimates. This achievement marks a significant advancement in the ability to chart underwater topography, an area covering over 70% of Earth’s surface. Researchers have long struggled to create detailed maps of the ocean floor, but the precision offered by SWOT represents a pivotal shift in marine exploration.

A recent study published in Science of The Total Environment reveals that microplastics have been contaminating freshwater ecosystems much earlier than previously believed. By examining caddisfly larvae collected from seemingly pristine streams in the Netherlands during the 1970s and 1980s, researchers discovered plastic particles embedded in the insects’ protective casings as early as 1971. This indicates that microplastics had already infiltrated freshwater environments once considered untouched, highlighting their long-standing presence in natural ecosystems.

Around 41,000 years ago, Earth underwent a dramatic magnetic event known as the Laschamps excursion, a period lasting about 2,000 years when the planet’s magnetic field nearly collapsed. During this episode, the magnetic field’s strength plummeted to just 10% of its current level, and the poles drifted chaotically across the globe. For about 300 of those years, the field became highly unstable, behaving like the complex magnetic environments found around outer planets. This weakening allowed high-energy solar particles to breach Earth’s atmosphere, with widespread consequences for climate, ecology, and possibly human evolution.

The Great Pacific Garbage Patch (GPGP) is often depicted as towering mounds of trash floating atop the ocean. However, these visuals are misleading. The reality is more subtle and insidious—what exists in the GPGP is not a visible island of debris but a vast “soup of microplastics” dispersed throughout the water column. While dramatic imagery captures public attention, it obscures the truth about the GPGP’s composition, its formation, and the threat it poses to marine ecosystems.

Google has unveiled a major leap forward in geospatial intelligence through the launch of new geospatial foundation models and a complementary research initiative called Geospatial Reasoning. These innovations integrate generative AI with geospatial data to accelerate problem solving in critical areas such as disaster response, public health, climate resilience, and commercial operations.

Despite being the most numerous and widely distributed class in the animal kingdom, insects remain vastly understudied. For every human on Earth, there are an estimated 1.4 billion insects, collectively outweighing us 70 times over. Yet, most conservation focus is reserved for charismatic species like bees and butterflies, leaving the majority of insect life poorly understood. This lack of comprehensive data is a significant barrier to addressing the global issue of insect population decline.

A recent study has uncovered a remarkable geological process occurring deep beneath the Midwestern United States: a buried remnant of an ancient tectonic plate, known as the Farallon slab, is pulling the underside of the North American crust down into the mantle. This phenomenon is resulting in what scientists describe as “drips” of rock that extend up to 400 miles (640 kilometers) deep into the Earth. These mantle drips, spread beneath a region from Michigan to Nebraska and Alabama, suggest a large-scale reconfiguration of the continent’s subsurface.

Researchers have made a groundbreaking discovery that reshapes our understanding of Earth’s first crust and the early geological history of the planet. A new study published in Nature suggests that the very first crust, which formed around 4.5 billion years ago, already possessed the unique chemical signature found in today’s continental crust. This challenges the long-held assumption that such signatures could only result from plate tectonic activity, particularly the process of subduction—where one tectonic plate dives beneath another.

In the next few decades, advancements in telescope technology will allow scientists to directly image Earth-sized exoplanets in Earth-like orbits around Sun-like stars. Current estimates suggest that the Milky Way alone contains around 10 billion habitable planets, making it statistically likely that some of them harbor life. Even though these distant worlds may initially appear as a single pixel in our instruments, future telescopes will be able to analyze their atmospheres, continents, oceans, icecaps, and cloud formations—bringing us closer to identifying potentially inhabited planets.

Forests play a critical role in combating climate change by regulating temperatures, purifying air and water, and supporting biodiversity. One of their most vital functions is forest carbon storage, as they absorb and retain carbon dioxide in trees and soil, helping to mitigate global warming. While oceans also serve as carbon sinks, forests offer a land-based solution that can be actively managed. However, simply planting more trees is not enough—different species provide varying benefits, and their effectiveness in carbon sequestration depends on environmental factors.
