Cockroach infestations don’t just bring creepy crawlers, they fill homes with allergens and bacterial toxins that can trigger asthma and allergies. NC State researchers found that larger infestations meant higher toxin levels, especially from ...
Researchers have, for the first time, estimated how quickly E. coli bacteria can spread between people — and one strain moves as fast as swine flu. Using genomic data from the UK and Norway, scientists modeled bacterial transmission rates and ...
When Surtsey erupted from the sea in 1963, it became a living experiment in how life begins anew. Decades later, scientists discovered that the plants colonizing this young island weren’t carried by the wind or floating on ocean currents, but ...
Beneath the ocean’s surface, bacteria have evolved specialized enzymes that can digest PET plastic, the material used in bottles and clothes. Researchers at KAUST discovered that a unique molecular signature distinguishes enzymes capable of ...
A collaboration between Brazilian and German researchers has led to a sunflower-based meat substitute that’s high in protein and minerals. The new ingredient, made from refined sunflower flour, delivers excellent nutritional value and a mild ...
Scientists uncovered how the amino acid leucine enhances mitochondrial efficiency by preserving crucial proteins that drive energy production. By downregulating the protein SEL1L, leucine prevents unnecessary degradation and strengthens the cell’s ...
Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that block infection. Understanding this mechanism could ...
UC Davis scientists uncovered Aptostichus ramirezae, a new trapdoor spider species living under California’s dunes. Genetic analysis revealed it was distinct from its close relative, Aptostichus simus. The species was named after pioneering ...
Earth’s climate balance isn’t just governed by the slow weathering of silicate rocks, which capture carbon and stabilize temperature over eons. New research reveals that biological and oceanic feedback loops—especially involving algae, ...
A pandemic-era breakthrough has allowed scientists to literally expand our view of plankton. By using ultrastructure expansion microscopy, researchers visualized the inner workings of hundreds of marine species for the first time. The effort, tied ...
Researchers discovered that soil microbes in Kansas carry drought “memories” that affect how plants grow and survive. Native plants showed stronger responses to these microbial legacies than crops like corn, hinting at co-evolution over time. ...
From mini-brains to spider-inspired gloves and wolf apple coatings, scientists are turning eerie-sounding experiments into real innovations that could revolutionize health and sustainability. Lab-grown brain organoids may replace animal testing, ...
