A major new study provides evidence that environmental factors, not genetics, are the primary drivers behind the Flynn effect – the steady rise in IQ scores observed over the 20th century. Researchers analyzed IQ data from over 700,000 Norwegian males and found that changes in IQ occur even between brothers from the same family. This …
Our genes influence more than just our raw intelligence and problem-solving abilities. The latest discoveries in the genetics of intelligence are showing how our DNA shapes how we learn, our educational attainment, occupational success, and even our health outcomes. Genetic research is revealing the deep connections between inherited cognitive capacities and multiple aspects of life. …
Edible insects offer immense potential as a sustainable and nutritious protein source that could help feed the growing global population. Key facts: Nearly 2 billion people worldwide already eat insects as part of their diet and culture. Insects require far less resources (land, water, feed) to produce the same amount of protein as livestock. Farm-raised …
A large study of Finnish men found that lower IQ scores were associated with committing more crimes and engaging in a wider variety of criminal offenses. Men with the lowest IQ were the most likely to have criminal records, especially for violent crimes. However, the increase in criminal behavior was gradual as IQ decreased, rather …
Criminal behavior has complex origins. While social and psychological factors play a clear role, a growing body of research suggests biological factors also influence criminality. Here’s what the science says so far about the biology underlying criminal behavior. Key Facts: Genetics account for 40-60% of variance in antisocial behavior. Environmental factors also play a role. …
Semaglutide is emerging as a wonder drug for management of various metabolic diseases. Originally approved for type 2 diabetes, this glucagon like peptide-1 (GLP-1) receptor agonist is now showing promise for treating obesity, non-alcoholic steatohepatitis (NASH), and neurodegenerative diseases like Alzheimer’s and Parkinson’s. Let’s explore the therapeutic potential of semaglutide and how it acts as …
Obesity has reached epidemic levels globally, with serious health and economic consequences. While lifestyle factors play a key role, genetics also influence a person’s susceptibility to weight gain or difficulty losing weight. An emerging field called pharmacogenomics is uncovering how genetics impacts response to medications that cause weight gain as a side effect, as well …
Omega-3 fatty acids like DHA and EPA have been shown to benefit brain health and cognitive function. Key facts: Omega-3s make up a large proportion of the brain’s fatty acid content. DHA is the most abundant. They support neuron growth, improve blood flow, and protect against inflammation. Multiple studies link omega-3 intake to better memory, …
A new study reveals that people who identify as liberal or left-leaning politically exhibit greater neural empathy responses compared to conservatives. The findings provide novel neuroscientific evidence that ideological differences extend to brain function during empathy. Key Facts: Researchers used MEG brain imaging to measure neural empathy responses in 55 participants as they observed others’ …
Human intelligence is a complex cognitive trait that has fascinated scientists and philosophers for centuries. New research is shedding light on the neurobiological underpinnings of intelligence, from genes to cells to brain networks. Key Facts: Intelligence is one of the most heritable human behavioral traits, with genetics explaining 50-80% of variability between individuals. Over 1000 …
