(Phys.org)—Researchers using computer simulations and modeling have come up with two possible explanations for the phenomenon known as true polar wandering. The team led by Jessica Creveling of Harvard University, suggest ...
In everyday objects, there is no left without right or front without back. Just as inseparable seem to be the electron's electric charge and its "spin." But in a strictly one-dimensional quantum world, both quantum properties ...

By stretching like a rubber band to more than 25 times its original length, a new nanogenerator has set a new stretchability record. The triboelectric nanogenerator's 2500% stretchability represents a significant increase ...
You watched the blood flow from your arm into a vial. The technician capped the vial and secured with a rubber band the scrap of paper containing your name and patient information. When you call to get the results of the ...
