A team of researchers tested morin, a plant compound, against gum disease bacteria and found strong antimicrobial benefits. By encapsulating it in polymers, they created a powdered form for oral hygiene products. This could replace antibiotics, avoid side effects from existing treatments, and help vulnerable patients maintain oral health.
Pollen holds a secret that could save honeybees
Scientists have discovered that pollen is a hidden source of natural medicine for honeybees. Symbiotic bacteria called Streptomyces produce antimicrobial compounds that fight deadly bee and plant pathogens. Bees collect these bacteria along with pollen and store them in hives, creating a natural defense system. This could lead to new,...
Black mamba venom has a deadly hidden second strike
Scientists have uncovered a dangerous hidden feature in Black Mamba venom that explains why antivenoms sometimes fail. The study revealed that several mamba species launch a dual neurological attack, first causing limp paralysis and then unleashing painful spasms once treatment begins.
First living cochlea outside the body shows how hearing really works
Scientists have kept a tiny slice of cochlea alive outside the body, directly witnessing how hair cells amplify sound. The finding confirms a universal principle of hearing and could pave the way for long-sought treatments for hearing loss.
This tiny butterfly has the most chromosomes of any animal on Earth
Scientists have confirmed that the Atlas blue butterfly carries the most chromosomes of any animal, with 229 pairs. Unlike duplication, its chromosomes split apart, reshaping its genome in surprising ways. This discovery sheds light on evolution, conservation, and even cancer research.
Stunning images reveal how antibiotics shatter bacterial defenses
Researchers have revealed how polymyxins, crucial last-resort antibiotics, break down bacterial armor by forcing cells to overproduce and shed it. Astonishingly, the drugs only kill bacteria when they’re active, leaving dormant cells untouched. This discovery could explain recurring infections and inspire strategies to wake bacteria up before treatment.
Miscarriages, down syndrome, and infertility all linked to this hidden DNA process
Human fertility hinges on a delicate molecular ballet that begins even before birth. UC Davis researchers have uncovered how special protein networks safeguard chromosomes as eggs and sperm form, ensuring genetic stability across generations. Using yeast as a model, they revealed how crossovers between chromosomes are protected for decades in...
Fossils in germany reveal a Jurassic sea monster with a swordfish snout
Scientists have named a new ichthyosaur, Eurhinosaurus mistelgauensis, from fossils found in Mistelgau, Germany. The marine reptile had a dramatic overbite similar to swordfish and unique skeletal traits that set it apart from other species. The discovery underscores Mistelgau’s global significance as a Jurassic fossil site, with more studies underway...
The accidental discovery that forged the Iron Age
Ancient copper smelters may have accidentally set the stage for the Iron Age. At a 3,000-year-old workshop in Georgia, researchers discovered that metalworkers were using iron oxide not to smelt iron but to improve copper yields. This experimentation shows how curiosity with materials could have sparked one of history’s greatest...
Scientists just found rare spores inside a fossil older than dinosaurs
Scientists reclassified a long-misunderstood fossil from Brazil as a new genus, Franscinella riograndensis. Using advanced microscopy, they discovered spores preserved in situ—a rare find that links fossil plants to microfossil records. The breakthrough reshapes knowledge of Permian ecosystems and highlights the power of revisiting classic fossils with new tools.
