Penn-led Team Uncovers the Physiology Behind the Hour-long Mating Call of Midshipman Fish

Penn-led Team Uncovers the Physiology Behind the Hour-long Mating Call of Midshipman Fish

According to the Guinness World Records, the longest any person has held a continuous vocal note is just shy of two minutes. That’s quite an achievement.Compared to the Pacific midshipman fish, however, the endurance of the human vocal cord is no match. Midshipman fish can generate a mating call that emits continuously from their bodies for a full hour.

‘Silent Code’ of Nucleotides, Not Amino Acids, Determines Discrete Functions of Proteins Vital For Life

‘Silent Code’ of Nucleotides, Not Amino Acids, Determines Discrete Functions of Proteins Vital For Life

Humans possess six forms of the protein actin, which perform essential functions in the body. Two in particular, β-actin and γ-actin, are nearly identical, only differing by four amino acids. Yet these near-twin proteins carry out distinct roles. A long standing question for biologists has been, how is this possible?
