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, a research initiative to place machine learning infrastructure in space, using solar-powered satellites to scale AI compute beyond Earth. Google published details and early findings on its research blog. The proposal is drawing attention for its ambition and for questions about cost, thermal challenges, and whether orbital data centers are realistic.

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.

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.

Scientists may have misinterpreted a geological clue dating back roughly 2 billion years, according to a new report highlighted by ScienceDaily. The finding suggests that assumptions about Earth's ancient history could need revising, with potential implications for how researchers understand the planet's early environmental and climate conditions. Details of the specific evidence and the scientific debate remain limited.

Researchers report the discovery of a microorganism nicknamed the "fire amoeba" that survives at temperatures far beyond what was thought possible for life. The finding challenges established assumptions about the upper heat limit for living cells and could reshape understanding of where life can exist, including in extreme environments on Earth and potentially elsewhere. Coverage is highlighting how the organism survives conditions that would destroy most known biology.

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.

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.

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.

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.

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.

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.

Scientists are examining whether detonating a nuclear bomb could be used to deflect or destroy an asteroid on a collision course with Earth, an idea long explored in fiction now under serious study. French science media are discussing how such a planetary defence plan would work, the physics involved, and what testing it would actually entail.

Google is preparing to test its AI chips in space, according to a report carried by The Brussels Times. The move suggests the company is exploring how its custom AI hardware performs outside Earth, though details on the mission, timeline and partners have not been disclosed. Observers of the semiconductor and space industries are watching for what this could mean for satellite computing and data processing in orbit.

A study published in Science argues that a Mega El Niño pattern, producing extreme and prolonged climate swings, triggered the end-Permian mass extinction around 252 million years ago, the deadliest extinction event in Earth's history. The researchers say runaway warming destabilised ecosystems beyond what species could tolerate. The paper is being shared widely, with an open-access version of the full text available.

Google is moving forward with its plan to test data centers in space, taking its unusual experiment beyond Earth. The idea is to run computing infrastructure on satellites, where solar power is more abundant and cooling is less constrained than on the ground. Commenters are treating it as one of the company's boldest infrastructure bets, with debate over whether orbital data centers can ever be practical or affordable.

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.

New research indicates that Earth microbes can survive under simulated conditions of the ocean beneath the ice of Saturn's moon Enceladus, suggesting life there is not out of the question. Scientists see the finding as encouraging for the search for life beyond Earth, since Enceladus's subsurface ocean is considered one of the most promising places to look.

Reports describe a single photon that traveled roughly 2 billion light-years before reaching Earth, a journey that current physics supposedly says should not have been possible. The claim is circulating widely, but no specific observatory, source event, or research team has been named, so the finding's details and significance remain unverified.
