Researchers have developed a teeth-whitening powder that works with the vibrations of an electric toothbrush to safely remove stains. Unlike traditional whiteners, it not only brightens teeth but also repairs enamel and supports healthy oral bacteria ...

Scientists have uncovered a hidden "death switch" in the brain that may be driving Alzheimer's disease--and even found a way to turn it off in mice. The culprit is a toxic pairing of two proteins that, when combined, triggers the destruction of brain ...

People often get the environmental impact of food wrong, according to new research. While many assume processed foods are the worst, they tend to overlook the surprisingly high impact of items like nuts and underestimate how damaging beef really is. ...

Tiny plastic particles aren't just choking oceans and cities--they're quietly infiltrating forests too. Scientists discovered that most microplastics arrive through the air, settling onto treetops before being washed or dropped to the forest floor in ...

A new blood test could change the outlook for one of the deadliest cancers--pancreatic cancer--by catching it much earlier than ever before. Researchers identified two previously unknown proteins in the blood that, when combined with existing markers ...

A surprising new study reveals that blocking a supposedly protective enzyme, Caspase-2, could actually backfire--raising the risk of chronic liver damage and cancer over time. Researchers found that without this enzyme, liver cells grow abnormally .. ...

Scientists have uncovered a surprising brain-based trigger for high blood pressure, tracing it to a small region in the brainstem that normally controls breathing. This area, which kicks in during forceful exhalations like coughing, laughing, or ...

Scientists in Australia have demonstrated a prototype quantum battery that could revolutionize energy storage. By harnessing quantum effects, it can absorb energy in a rapid "super absorption" event, enabling much faster charging than conventional .. ...

A decades-old superconducting mystery just took a surprising turn. Strontium ruthenate, a material that conducts electricity with zero resistance at low temperatures, has long puzzled scientists with hints of an exotic, complex superconducting state. ...

Scientists have created a new kind of time crystal using sound waves to levitate tiny beads in mid-air. These particles interact in a one-sided, unbalanced way, breaking the usual rules of motion and creating a steady, repeating rhythm. The system is ...
