Phys.org / Mirror-positioning method could make quantum gravity tests possible

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where a particle does not have a single definite value of position or momentum until it is measured. A ...

Phys.org / This nasal spray rewinds the aging brain, restoring memory and reversing inflammation in preclinical models

Picture this: your brain is a high-performance engine. Over decades, it doesn't just wear down, it also starts to run hot. Tiny "fires" of inflammation smolder deep within the brain's memory center, creating a persistent ...

Phys.org / Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover

When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at HZDR have now observed ...
