Caroline Conway, Biological Sciences, Summer 2021 When the Human Genome Project concluded, scientists were left with the full human DNA sequence and many revelations. One revelation was the identification of so-called “junk DNA” — repetitive DNA sequences that do not play a role in protein synthesis. It is estimated that … Continue reading

Caroline Conway, Biological Sciences, Summer 2021 Cheetahs, sloths, humans — whatever the animal, a new study proposed a mathematical model to calculate the maximum running speed, determining whether the animal in question could match highway speeds or would lose a race to a turtle. Based on the factors that go … Continue reading

Isabelle Wilson, Biological Sciences, Summer 2021 Figure: Depiction of the dopaminergic system for reward processing in the brain. Research at the University of California San Diego demonstrated that mice can anticipate dopamine impulses in the neocortex (including the nucleus accumbens and prefrontal cortex) to manipulate their corresponding motor response (Source: … Continue reading
