Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date the age of rock layers.
Answer:
Aspartame is found in Nutra sweet which is a modified dipeptide rather than a carbohydrate and they are many times sweeter than monosaccharides galactose because they binds very tightly with the heterodimer GPCR receptors present on the tongue which is made up of proteins called taste receptor type 1 member 2 and taste receptor type 1 member 3.
This tight binding to aspartame generates a neuronal output that is sent to the brain and the brain interprets it as a super sweet compound. It's decrease off rate also contribute to its more sweetening effect.
Therefore the type of binding to taste receptors explains why aspartame is 500 times sweeter in human taste test.
Uranium extraction from seawater: Uranium is most often mined from the Earth's crust, but it can also be extracted from seawater, which contains large quantities of uranium<span> (3.3 ppb, or 4.6 trillion kg). Theoretically, that amount would last for 5,700 years using conventional reactors to supply 15 TW of power.</span>
