Human neurons have a lower density of ion channels than expected, compared to neurons of other mammals, according to a new study. The researchers hypothesize that a lower channel density may have helped the human brain evolve to operate more efficiently.
R is the response to selection, S is the selection differential, and h 2 is the narrow-sense heritability. This is the workhorse equation for quantitative genetics. The selective differential S, is the difference between the population average and the average of the parental population (some subset of the total…
Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology.
Some people claim nuclear fuel is inexhaustible and circular, others say we'll run out soon. We do the math. Turns out, it's roughly as inexhaustible as sunlight.
