- 1El Niño reaches record strength, reshaping global weather●New data shows El Niño is strongest ever with major shift in global weather patterns | BBC News
New data indicates the current El Niño is the strongest ever recorded, driving a major shift in global weather patterns. The warming of the eastern Pacific is expected to bring droughts, floods and altered rainfall across multiple continents, with scientists warning communities to prepare for extreme conditions. The findings have prompted widespread discussion among climate experts and the public about what the record-strength event means for weather forecasts, agriculture and disaster planning worldwide.
- 2Scientists warn key planetary boundaries have been breached●'Planetary boundaries' necessary for flourishing of life have been breached
Scientists warn that several of the 'planetary boundaries' — thresholds for systems like climate, biodiversity and land use that keep Earth hospitable to life — have now been crossed, pushing the planet outside the safe operating space humanity has depended on. The findings point to escalating risks of irreversible environmental change, and debate is focusing on how far the breaches have gone and what policy action could still pull key indicators back within safe limits.
- 3Scientists seek new ways to fight mosquitoes as climate warms●Scientists explore new ways to target mosquitoes as warming climate expands threat
Researchers are developing new methods to control mosquitoes as warming temperatures lengthen mosquito seasons and expand the range of dangerous diseases such as malaria and dengue. The mosquito kills more people than any other animal on Earth, and scientists warn that longer warm periods give the insects more time to spread illness, prompting renewed focus on innovative control strategies.
- 4Scientists launch major effort to predict Mississippi Delta's future●Near the Mississippi’s mouth, scientists are trying to predict the future. ‘A massive effort.’
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 coast and ecosystems. The work is described as 'a massive effort' and focuses on how the river, land loss and environmental change will shape the delta in the decades ahead.
- 5Quantum Computer Operates in Space for the First Time●For The First Time, a Quantum Computer Has Operated in Space
Researchers have run a quantum computer in space for the first time, marking a milestone in quantum technology beyond Earth. The demonstration suggests quantum computing and communication systems could one day operate aboard satellites, where conditions differ sharply from ground-based laboratories. Scientists say the achievement could pave the way for space-based quantum networks and new experiments impossible on Earth, though details of the mission and hardware remain limited.

New research reported this week indicates that periods of climate change triggered rare, rapid bursts of evolutionary diversification in birds. The findings suggest that shifting environments repeatedly pushed bird lineages to adapt and split into new species, rather than evolving at a steady pace. Scientists say the work helps explain why bird diversity is distributed unevenly across the globe and how species may respond to today's warming climate.
- 7Saturn's moon Enceladus may ease the search for alien life▼Saturn’s icy moon Enceladus may make alien life easier to find than scientists thought
A new report suggests Enceladus, Saturn's icy moon, may make it easier than previously believed for scientists to detect signs of alien life. The moon is known for the plumes of water vapour erupting from its subsurface ocean, which space probes have already sampled. The claim is that biosignatures could be found more readily in that material than researchers assumed.
- 8New Microscope Captures Living Cells of Antarctic Fish●Researchers engineered a novel microscope capable of operating near 0 degrees Celsius, enabling the first-ever high-reso
Researchers have engineered a novel microscope capable of operating near 0 degrees Celsius, allowing the first-ever high-resolution observations of living cells in Antarctic fish. The work aims to reveal how these fish survive in extreme cold, a long-standing question in cryobiology and marine biology. Scientists say the technique could open new lines of research into cold-adapted life and cellular survival mechanisms.
- 9Scientists Decode Moth Sex Pheromones via Insect Smell Receptors●Scientists Reverse-Engineer Insect Smell Receptors to Identify Moth Sex Pheromones
Researchers have reverse-engineered insect smell receptors to identify the sex pheromones of moths. By understanding how the receptors detect these chemical signals, scientists hope to open new avenues for pest control, potentially allowing farmers to disrupt moth mating without heavy insecticide use. The work highlights growing interest in decoding insect olfaction for agricultural applications.
- 10Cuckoo Genetics Show Host Habits Alone Don't Split Species●Cuckoo Genes Reveal Host Habits Alone Cannot Divide a Wandering Species
New genetic research on cuckoos indicates that differences in host preferences are not enough on their own to divide the wide-ranging birds into separate species. The findings suggest that despite specialised egg-laying habits targeting different host birds, gene flow across populations keeps the wandering species genetically unified, complicating how scientists classify parasitic cuckoo lineages.
- 11US reef robot finds coral pillar with 25 times more fish●In 2026, a US reef robot found one coral pillar hiding nearly 25 times more fish and followed reef sounds
A US underwater robot has located a coral pillar hiding nearly 25 times more fish than surrounding reef, using reef sounds to navigate and identify hotspots. The 2026 finding suggests acoustic monitoring could transform how scientists survey reefs and prioritize conservation of dense fish habitats.
- 12Avian keratin disorder blamed for deformed beaks in Alaska chickadees●Scientists believe avian keratin disorder is cause of fishhook beaks in Alaska chickadee population
Scientists in Alaska say avian keratin disorder is behind the fishhook-shaped beaks appearing in the state's chickadee population. The condition causes abnormal growth of the birds' beaks, which can make feeding difficult. Researchers studying the disorder are working to understand its causes, and the findings have drawn attention given the unusual number of affected birds reported in the region.
