Norman Campbell discusses the problem of the possible consistency of the assumptions about the motion and arrangement of electrons in the atom underlying ... theory of atomic structure, and ...

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 ...

Imagine building a Lego tower with perfectly aligned blocks. Each block represents an atom in a tiny crystal, known as a ...

The two collaborations combined their complementary data on the proton's inner structure to improve calculations of a phenomenon in atomic physics: the hyperfine splitting of hydrogen. An atom of ...

“Current data processing, including structure model building, can take many days ... “Our software then uses these identified atom positions to construct the 3D structures of proteins and DNA/RNA. No ...

The study is published in Nature Communications. The scientists used cryo-electron microscopy to decipher the three-dimensional (3D) structure of the RNA polymerase. They shock-froze the RNA ...

They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino acids are characterized by their central carbon atom, known as the α-carbon, which is bonded ...
