A key to learning and studying chemistry is practice. Solving practice problems, working on equations and formulas should be a core feature of your daily study routine. Reviewing and working the ...

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

For comparison, the radius of a typical bacterium is 1 × 10-6 m and the radius of a human hair is about 1 × 10-4 m.

Researchers have provided a surprisingly simple explanation for the mechanism and features of the "Golgi apparatus" -- a structure that has baffled generations of scientists. The new model developed ...

In 1922, Niels Bohr won the Nobel Prize for Physics. He won it “for his services in the investigation of the structure of atoms and of the radiation emanating from them.” Naturally then, his Nobel ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

A computational model of the more than 26 million atoms in a DNA-packed viral capsid expands our understanding of virus structure and DNA dynamics, insights that could provide new research avenues and ...
