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…
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 outp…
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 pat…
Empoderando a las comunidades guatemaltecas afectadas por el plástico
Read this article in English. Esta historia cuenta con el apoyo del Centro Pulitzer. JALAPA, Guatemala—En una tarde calurosa y bochornosa, en el pequeño pueblo montañoso de El Dur…
Specific cover crops may help attract insects that target harmful pests
Different cover crops may affect how plants defend themselves against pests—including by attracting more insects that eat harmful caterpillars—according to a new study led by rese…
Discovery reveals rapid pathways to complex aromatic molecules in space
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 …
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 …
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.
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 s…
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…
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 fe…
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 …
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…
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 Tele…
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…
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 al…
Parental care can influence evolution, beetle experiments show
How has offspring dependence on parents evolved over the course of evolution? Researchers at the University of Bayreuth, in collaboration with Kyoto University, Japan, have invest…
How bacteria develop resistance to programmable antibiotics
Antimicrobial resistance is one of the greatest challenges facing modern medicine. A new class of programmable antibiotics known as asobiotics can be used to treat bacterial infec…
As Oceans Warm, Children Face Growing Malnutrition Risk
When ocean temperatures soar, the consequences reverberate beyond the water. In coastal communities, marine heat waves threaten livelihoods, food security and human health—particu…
Astronaut Jonny Kim leaves NASA, will return to active military duty
NASA astronaut Jonny Kim is leaving the space agency to continue his military career. Kim, who's also a medical doctor, completed one spaceflight during his NASA career.
Study on biodiversity conservation in agriculture and forestry: High motivation, few options
Farmers and foresters manage around 80% of Germany's land area. They are therefore key agents of change in protecting biodiversity—and are often accused of not doing enough to pro…
