Hitting bacteria hard and early with diverse phage cocktails may curb resistance
As multidrug antibiotic resistance emerges as a potent public health challenge, medical science has renewed attention on the potential for bacteriophage therapy. Bacteriophages, or phages, are viruses that target, infect and replicate inside bacteria, destroying them in the…
Evolution favors flatter paths when fitness outcomes are equal, study finds
A surprising discovery by Technion researchers sheds new light on the dynamics of evolution. Published in the Proceedings of the National Academy of Sciences, the study shows that when an organism has several evolutionary paths available with equal fitness, the path it follows…
Tiny oxygen gaps may determine whether next-generation memory films store data well
Researchers have captured in real time the "birth moment" when the performance of a next-generation memory material is determined. The key lies in controlling oxygen vacancies, microscopic defects created when oxygen atoms are missing from their normal positions.
Boosting soybean protein: Zinc and sulfur essential in sustainable crop production
Soybean is a critical element of the global food supply: Between its use for animal feed and human consumption, it accounts for roughly two-thirds of plant-based protein meal output worldwide. Canada is a global leader in sustainable soybean production, with 70% of its crop, one…
Primed and ready to fight, a nematode pheromone arms plants to battle pathogens
When cold and flu season comes around, we take steps like getting our flu shots and taking immune supplements to strengthen our bodies' defenses against pathogens. Plants face pathogenic threats, too. Plant pathogens can have devastating effects on crop yields, with up to 40% of…

A team of researchers led by the University of Hawaiʻi at Mānoa Department of Chemistry has uncovered a faster way large carbon-based molecules may form in space, helping solve a long-standing mystery about how some of the building blocks of the universe grow.
Molecular makeover brightens organic light near 1,000 nanometers
Near-infrared organic light-emitting diodes (OLEDs) that emit about 1,000 nanometers could support biomedical and security technologies. Yet pushing organic light to these longer wavelengths usually causes a steep drop in efficiency. As the energy gap becomes smaller, molecular…

With Hong Kong recently recording record-breaking high temperatures, extreme weather has once again raised public awareness of global warming and emission-reduction measures. A large-scale international study led by The Hong Kong University of Science and Technology (HKUST) has…
AI model designs potentially stable protein sequences beyond those found in nature
A protein's function is determined by its structure, and structure—the way a protein folds—is determined by its sequence of amino acids, the building blocks of proteins.
Short, intense storms gain intensity across Hawaiʻi
While long-term data show that Hawaiʻi is getting drier overall, short, intense downpours that cause sudden, dangerous flash floods are getting stronger on the islands, according to a new study by researchers at the University of Hawaiʻi at Mānoa.
Shear flow in narrow channels sparks amyloid formation, experiments reveal
Many cars and not enough lanes is a recipe for traffic jams. Now, researchers from Japan show that even proteins can get backed up and start behaving poorly when too many try to squeeze too quickly through a small space.
Heat-tolerant corals may be more vulnerable to disease
Corals that partner with heat-tolerant algae may be better equipped to survive warming oceans—but that resilience comes with an unexpected trade-off, according to a new study from Boston University published in Science Advances.
MOF-coated catalyst converts CO₂ to CO nearly five times faster under ultrasonic vibration
Researchers at the University of Osaka have developed a catalyst that uses mechanical vibration to convert carbon dioxide (CO2) into carbon monoxide (CO), an important chemical feedstock. The catalyst consists of barium titanate (BaTiO3) coated with a metal-organic framework…
Mixture of traditional edible plants inhibits fungus growth in corn, study shows
Fungal contamination in stored grain across sub-Saharan Africa causes major post-harvest losses and severe public health risks, costing billions of dollars annually, according to the Food and Agriculture Organization of the United Nations (FAO). High humidity, warm temperatures…
Texas fossil reveals early insects kept aquatic limbs during move onto land
The formation of complex terrestrial ecosystems was a significant innovation in the evolutionary history of life on Earth. This event signified the expansion of life beyond marine environments and marked the beginning of a new phase in the diversification of terrestrial biota.
Groundbreaking literacy program triples rate of progress among struggling young readers
A University of Alberta literacy expert has completed the largest reading intervention in Canadian history, tripling the rate of progress for most participants after just five months. Preliminary results show that about half of the children in the program require no further…
ASTRID traces 13.5 billion years of black hole and galaxy evolution
In dark skies at night, distant starlight twinkles and speaks to vast cosmic histories almost as old as time itself. New data from instruments such as NASA's James Webb Space Telescope are helping astrophysicists probe deep cosmic mysteries, including the evolution of black…
Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar system orbit the sun.
James Webb Space Telescope observes 72 stars and finds planet formation is a race against time
Using the James Webb Space Telescope, astronomers have studied 72 young sun-like stars to discover that forming planets is a real race against time.
Fast but error-prone AI assists in solving a decades-old fluid mechanics problem in five weeks
An AI assistant helped University of Colorado Boulder researchers solve a mathematical problem that had challenged their lab for a year and a half, though it made subtle errors along the way. The breakthrough could improve how scientists study nanoparticles—tiny particles about…
Social media posts reveal how communities cope with extreme heat
As extreme heat becomes more frequent and intense across California, knowing which communities are struggling and what kind of help they need is increasingly important for protecting public health. A new UC Irvine study suggests that part of the answer may be hiding in everyday…
A few minutes of freezing can change the fate of iron in nature
Just a few minutes of freezing and thawing can have a decisive impact on how ferrihydrite, the most reactive iron mineral in cold soils, permafrost and glaciers, transforms, according to researchers at Umeå University. As climate warming intensifies freeze-thaw cycles and…
