Scientists have discovered why chemical reactions are slowed down in mirrored cavities, where molecules interact with light. The team used Quantum-Electrodynamical Density-Functional Theory to find that the conditions inside the optical cavity affected the energy that makes atoms vibrate around the mol...

hydrogen seems most plentiful in iron-rich rocks like olivine. The gas forms when chemical reactions at elevated temperature and pressure underground pull water apart. (There’s also likely another mechanism that forms hydrogen underground, called radiolysis, where radioactive elements emit radiation tha...
Which evolutionary process does not change allele frequencies over time but causes a deviation from Hardy-Weinberg proportions? Explain how enzymes initiate chemical reactions. Explain how a nucleotide base might be changed without changing the protein? Why do cells need exposure to T_3 for their no...
