The collective movement of nanorobots observed in vivo

Nanobots are machines whose components are at the nano-scale (one-millionth of a millimeter), and can be designed in such a way that they have the ability to move autonomously in fluids. Although they are still in the research ...

Colliding molecules and antiparticles

Antiparticles—subatomic particles that have exactly opposite properties to those that make up everyday matter—may seem like a concept out of science fiction, but they are real, and the study of matter-antimatter interactions ...

Supplying high-quality cancer-imaging isotopes

Zirconium-89 is a radionuclide that's just right for cancer tumor imaging. When the isotope is combined with a tumor-seeking molecule, it lasts long enough in the body to find the tumor and to be imaged. Researchers developed ...

Coming soon: A blood test for Alzheimer's disease?

People with symptoms of Alzheimer's disease (AD), such as cognitive difficulties, behavior changes and mood swings, may wait months or even years to get a definitive diagnosis. That's because doctors lack a simple, accurate ...

Doubly-excited electrons reach new energy states

Positrons are short-lived subatomic particle with the same mass as electrons and a positive charge. They are used in medicine, e.g. in positron emission tomography (PET), a diagnostic imaging method for metabolic disorders. ...
