The segment examines research approaches to targeting mosquitoes as warming climate conditions push the public health threat into previously unaffected regions.

Guardian science writer Linda Geddes reports on the growing threat of wildfires in the UK, where hotter, drier summers are turning green landscapes into tinderboxes. Scientists are working to map, model and predict how fires spread so that outbreaks can be prevented or contained earlier, as Britain confronts a type of risk once seen mainly abroad.

New findings indicate Mercury is contracting more quickly than previous estimates suggested. The smallest planet in the solar system has been cooling and shrinking for billions of years, causing its crust to wrinkle and crack. The updated measurements challenge existing models of how the planet's interior cools, prompting discussion among planetary scientists about what this reveals about Mercury's geological evolution.

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.

President Trump pledged to reveal the truth about unidentified flying objects, drawing attention from scientists who hoped for the release of government data on aerial phenomena. Researchers say that despite the promises, concrete disclosures and verifiable evidence have yet to materialise, leaving the scientific community frustrated and still waiting for answers about unexplained sightings.

A new study is probing whether artificial intelligence systems can experience pain or suffering, adding to a growing body of research on machine sentience and AI welfare. The findings have sparked debate among scientists and commentators about how to test subjective experience in machines and what ethical obligations, if any, would follow if AI systems could feel.

New research from the University of Arizona analysing decades of satellite imagery finds that the world's drylands, though greening as vegetation responds to rising carbon dioxide, are increasingly locked into extreme 'boom-and-bust' cycles — rapid plant growth followed by sudden collapses. Scientists warn the pattern could destabilise ecosystems and the communities that depend on them.

Researchers report discovering a molecular switch activated by stress that appears to drive depression, offering a potential biological mechanism for the condition. The finding, covered by science news outlets, could point toward new drug targets for treating stress-related mood disorders, though details of the study and its evidence remain limited in initial reports.

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.

New research suggests radiation exposure could trigger a hallmark of Alzheimer's disease in the brain, adding to concerns about the neurological effects of radiation from medical treatments, occupational settings or space travel. The finding points to possible mechanisms linking radiation to dementia-like changes, though scientists caution more work is needed to confirm the risk in humans.

Scientists are conducting a large-scale research effort near the mouth of the Mississippi River in Louisiana, working to predict the future of the region's environment. The project, described as 'a massive effort,' focuses on understanding how the delta and surrounding coast may change, an area central to Louisiana's ongoing land-loss and restoration challenges.

Researchers have identified a new potential treatment target for high blood pressure, a condition affecting over a billion people worldwide and a leading risk factor for heart disease and stroke. The discovery could open the door to new drug development beyond existing blood pressure medications. Details of the findings and their clinical significance remain limited.

Nasa scientists are travelling to observe a rare solar eclipse, according to BBC News. Eclipses offer researchers a brief window to study the Sun's corona and test instruments that cannot gather this data at any other time. Teams often deploy to remote viewing paths for just minutes of totality, making each event a costly, carefully planned scientific operation drawing public curiosity.

Researchers have successfully generated solar power from panels placed 10 metres below the sea surface, according to a Euronews report.
