Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic ...

The theoretically predicted value for the shift allows the fine-structure constant to be measured with ... a group of three scientists from the Max Planck Institute for Nuclear Physics in Germany.

Now, the kilogram is defined in relation to the Planck constant, the smallest amount of energy a photon can carry. With this constant, scientists can make ultra-precise mass measurements using the ...
