The end of humanity? What would happen if the Yellowstone supervolcano erupted now

A Yellowstone super-eruption would begin not with a sudden surprise, but with weeks of increasingly alarming warning signs such as migrating earthquake swarms, rapid ground uplift, changing geysers, and rising volcanic gases. In a worst-case scenario, those signals could culminate in a VEI 8 eruption that blasts ash tens of kilometers into the atmosphere, unleashes deadly pyroclastic flows, buries parts of the western United States in ash, and cripples transportation, electricity, water systems, agriculture, and communications across much of North America.

Brain scans reveal a possible cause of long COVID fatigue and brain fog

Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that target the brain's dopamine system.

Scientists discover first new penguin species in more than 100 years

Genetic evidence has revealed a previously unknown gentoo penguin species on the remote Kerguelen Islands and shown that gentoos actually consist of four distinct species. The discovery also highlights a growing threat, as warming oceans could leave several island populations with little suitable habitat by 2050.

Fast-food brands may build loyalty through emotional experiences, not service alone

A study of more than 800 fast-food customers suggests that loyalty to a brand is shaped not only by satisfaction with the product or service but also by customers' emotional experiences. The study, published in the International Journal of Internet Marketing and Advertising, focused on fast-food consumers in Peru but could have implications for fast-food brands in other emerging markets.

Stem cells reverse stroke damage and restore movement in mice

Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.

Researcher studies mystical gemstones with a future in space exploration

Ph.D. candidate Natalia Seliutina has followed gemstones from the -30° temperatures of Siberia to the carving studios of Ōtepoti and the particle accelerators of Taiwan in her quest to discover why pounamu is one of the toughest natural materials on Earth. Fresh from the publication of Natalia's paper in the New Zealand Journal of Geology and Geophysics, Kathryn van Beek catches up with her to find out how understanding the properties of pounamu might one day help us explore space.

Fairness-based pathways shift emissions cuts while preserving global climate goals

Who cuts emissions fastest, and who supports others in doing so, are central questions in global climate action. New IIASA-led research shows that building fairness into climate models from the start can inform deliberations without changing the overall climate goal.

Urban segregation study traces how history and ecology shape inequality in southern Chile

Segregation is a multidimensional phenomenon deeply intertwined with historical, social and ecological contexts. Yet this more integrated perspective has received limited attention in the Global South. A recent study focusing on the city of Valdivia offers an exception, examining three key historical moments: colonization, the devastating 1960 earthquake and current struggles to protect urban wetlands.

Global cooperation under pressureβ€”new report on shaping reforms

Geopolitical rivalry, conflict, authoritarian nationalism and the systematic erosion of rules-based politics are reshaping the global order and putting cooperation under growing pressure. Yet the picture is more nuanced: While disruptive trends dominate the headlines, reforms are taking shape at the same time.

Cyanobacterium found in clean lakes shows little toxic potential

Gloeotrichia echinulata is a type of cyanobacterium that draws scrutiny because it tends to bloom in clear lakes, forming thick mats of visible green or white puffballs in otherwise clean water. Because of the slew of toxic compounds cyanobacteria can produce, blooms (historically called "blue-green algae") are of growing global concern. Yet, a new study by researchers at Bigelow Laboratory for Ocean Sciences and Oregon State University suggests this particular species might not deserve its maligned reputation.
