Scientists are developing new methods to control mosquitoes as climate change lengthens mosquito season and expands the range of disease-carrying species. The mosquito kills more people than any other animal on earth, spreading diseases such as malaria and dengue, and longer warm seasons give the insects more time to transmit dangerous illnesses. Climate researchers warn the public health threat is growing.

Google has unveiled Project Suncatcher, an initiative to run machine learning infrastructure in space, with details published on its research blog. The plan points to solar-powered data centers orbiting Earth to expand computing capacity for AI. The announcement is drawing attention among technologists debating the feasibility, cost and environmental logic of moving AI compute off-planet.

Four environmental organizations filed a petition Thursday urging the Federal Communications Commission to reverse its approval of a startup's plan to beam on-demand sunlight from space to Earth. The groups argue the agency ignored the project's potential impacts on wildlife and astronomy, reigniting debate over regulating commercial space ventures and their environmental consequences.

A new report suggests scientists may have misinterpreted evidence dating back some two billion years, with potential implications for how Earth's early history is understood. The finding is drawing attention in science media, as re-evaluating such ancient clues could reshape assumptions about the planet's past conditions and evolution.

Scientists report that dust levels in Earth's atmosphere have declined, reversing a long-running trend. The shift is described as mysterious because its cause is not yet understood. Dust in the atmosphere affects climate, air quality and ocean ecosystems, so the change could have far-reaching implications for climate modeling.

New research points to the Earth's crust actively stretching and tearing beneath the Pacific Northwest, the region sitting atop the Cascadia subduction zone. The finding has drawn attention from science readers concerned about earthquake risk in Oregon, Washington and British Columbia, and what deep tectonic activity could mean for future seismic hazards.

New research suggests icy moons in the outer solar system could retain their subsurface oceans even if they are shattered by large impacts, with fragments potentially holding on to liquid water. The finding has implications for the search for life, as it widens the range of places where habitable conditions might survive dramatic collisions and reassembling events over billions of years.

An analysis published by the Observer Research Foundation examines how solar activity can trigger disasters on Earth, warning that solar storms threaten power grids and digital infrastructure. The piece highlights the vulnerability of modern electricity networks and communications systems to severe space weather events, and the potential scale of disruption if a major storm were to hit.

DARPA is developing a robotic spacecraft designed to service and repair satellites in geosynchronous orbit, roughly 36,000 kilometers above Earth. The program, profiled by IEEE Spectrum, would allow aging or malfunctioning satellites to be fixed or refueled in place, extending their working lives. Interest centers on the technical challenge of robotic operations at that altitude and what orbital servicing could mean for the satellite industry and space security.

Federal authorities have seized a 54-pound Martian meteorite that was sold at auction last year, with U.S. attorney Jeanine Pirro asserting that the space rock now belongs to the United States. The move raises questions about who holds legal title to meteorites found on Earth and traded through private auction houses, and it has drawn attention to the murky rules governing ownership of extraterrestrial material.

Scientists have captured a subduction zone off Vancouver Island in the process of tearing itself apart, suggesting these massive tectonic systems may die piece by piece rather than all at once. The finding offers new insight into how subduction zones end over geological time, with implications for understanding seismic hazards in the Pacific Northwest, where the Cascadia zone poses earthquake and tsunami risks.

Google is moving forward with an unusual experiment to test running data centers in orbit, a project long discussed as a way to harness continuous solar power and ease the energy and cooling demands of AI computing. The news that the project is finally leaving Earth is drawing attention across the tech press, with observers weighing whether space-based infrastructure could become a realistic answer to data centers' growing power needs.

French science outlet Futura reports that scientists are examining whether a nuclear detonation could be used to save Earth, most likely by deflecting a dangerous asteroid on a collision course with the planet. The idea, long confined to Hollywood films like Armageddon, is now being seriously studied by researchers, who are running tests and simulations on what they call the unthinkable scenario.

The New York Times reports on a scientific discovery connected to an $80 motel room that researchers say could shed light on the origins of life. Details of the finding and the scientists involved remain limited, but the story highlights how an ordinary roadside room became tied to research into how life first emerged on Earth.

Google has announced Project Suncatcher, an initiative to test its AI chips in space for the first time. The plan points to putting data-processing hardware aboard satellites, a step that could eventually move parts of AI computing off Earth. The announcement is drawing attention across the tech and semiconductor world, with observers weighing the engineering challenges of running chips in orbit and what it could mean for the future of data centers.

A robotic submarine deployed beneath Antarctic ice mapped unusual structures on the seafloor before disappearing without a trace. The lost vehicle reportedly recorded strange formations under the ice shelf before contact was cut off. The disappearance has drawn attention because the sub was gathering rare data from one of the least explored environments on Earth, raising questions about what it found and why contact was lost.

Researchers analysing the evolutionary history of 163 ant genomes, spanning most extant ant subfamilies, found periods of rapid species diversification over the past 100 million years were associated with heightened activity of transposable elements — DNA sequences that move within the genome. The findings suggest genome dynamics played a role in the evolutionary success of ants, one of the most dominant insect groups on Earth.
