Can music change DNA?

Though music clearly affects our brains, scientists didn't know what caused those mental changes on a molecular level — until now. Scientists at the University of Helsinki have made the amazing discovery, published in PeerJ, that listening to classical music actually alters the function of your genes.

Scientists have known for a while now that listening to music has a bounty of physical and mental benefits: It reduces blood pressure, causes the release of dopamine and even improves muscle function. Though music clearly affects our brains, scientists didn't know what caused those mental changes on a molecular level — until now. Scientists at the University of Helsinki have made the amazing discovery, published in PeerJ, that listening to classical music actually alters the function of your genes. Scientists took blood samples from study participants before and after listening to Mozart's Violin Concerto No. 3 in G major, K.216. Scientists found that the music directly affects human RNA, suggesting that listening to music has even more surprising benefits than previously thought. It affects the very core of your biological being. More detailed than ever: This is an unprecedented amount of insight into how exactly music influences human beings. Scientists have previously used PET scans to watch the brain as it processes music. But with the introduction of genomics, scientists can look even closer by sampling blood and identifying its molecular properties. 48 people participated in this study, and they were split into two groups: those who had musical experience and those who were inexperienced. What the researchers found in the experienced group was striking. Good for you in every way: For the musically inclined group, the study uncovered huge genetic benefits after listening to classical music. Listening to music increased expression of the glucocorticoid receptor, which regulates stress, depression and even addictive behaviors. Not only that, listening to music also inhibits dopamine reuptake, meaning that the brain has more of the molecule that regulates the brain's reward center. "Listening to classical music enhanced the activity of genes that are mainly related to reward and pleasure, cognitive functions and proper brain function," Chakravarthi Kanduri, Computational Biology Researcher at the University of Helsinki, wrote Mic. "Some of the findings of this study may explain the molecular mechanisms underlying music therapy." Music does all this by getting the good genes moving — specifically, those that help with mood, memory, learning and basic brain function. But music also slows down bad genes that cause brain degeneration, meaning that listening to music actually acts like a brain shield. A set of the genes affected are the same genes that help songbirds learn new songs. This suggests that there may actually be a shared, deep evolutionary background between our love of music and birds' use of music — a link some classical musicians may already have intuited. All the more reason to learn music: The study found the strongest responses among those familiar with music — participants without musical backgrounds didn't experience any noticeable benefits. These findings only cemented the fact that childhood music lessons are extremely beneficial to cognitive function: "We observed no significant findings in musically inexperienced participants," either naturally or through lack of learning, the study authors wrote. But Kanduri still thinks it might influence everyone positively. "We cannot exclude the possibility of a similar effect in musically inexperienced participants," Kanduri wrote. "Several factors such as age, gender, personal preferences of music genres, familiarity of music compositions and duration of listening may affect the transcriptional responses." Whether or not classical music affects the less musically inclined equally, the list of reasons to learn music just got a lot more compelling. It's never been clearer that music really can change us.

What is a genius IQ?

Notably, the average IQ score falls between 85 and 115. A score above 140, meanwhile, is considered to be genius level. 1:00.

While Washington, D.C. leaders fight over who's more intelligent, billionaire businessman Warren Buffett says there's a specific IQ score you need to succeed: 130. A week after NBC reported that Secretary Rex Tillerson called President Donald Trump a "moron," Trump proposed the two compare IQ tests in an interview published on Tuesday by Forbes. "And I can tell you who is going to win," Trump adds. This wouldn't be the first time Trump has bragged about his IQ.

Mensa, an exclusive organization for those who score in the top two percent, has offered to conduct Trump and Tillerson's IQ test. But Buffett has long said that IQ isn't the single defining factor to being successful. More important than IQ, he says, is rationality and emotional stability. "You don't need to be a rocket scientist. Investing is not a game where the guy with the 160 IQ beats the guy with a 130 IQ. Rationality is essential," Buffett is quoted saying in the book, "Warren Buffett Speaks." Notably, the average IQ score falls between 85 and 115. A score above 140, meanwhile, is considered to be genius level.
