(Phys.org)—It would seem that figuring out how many molecules of water are needed to form the smallest, or most basic ice crystal would have been discovered long ago, but that is not the case, because to measure both the ...
(Phys.org)—Creating 3D visualizations of hydrogen atoms in proteins is especially challenging, often requiring their locations to be inferred from those of nearby carbon, nitrogen, oxygen or sulfur atoms stored in protein ...
(Phys.org)—A new study of the sense of smell lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules.
