Why does human health decline as we age? Do all creatures age in the same way? Biotech researcher and author of Jellyfish Age Backwards, Nicklas Brendborg, explains the top two theories on human aging: genetic wear-and-tear and planned obsolescence. However, he notes that these aging patterns don’t hold true across all of nature. Read below to learn more about human aging process theories.

Leonard Mlodinow’s Subliminal (Book Overview & Takeaways)

Why do you sometimes make decisions without knowing exactly why? How much of your everyday thoughts, feelings, and behaviors are shaped by processes you’re not aware of? Leonard Mlodinow’s Subliminal: How Your Unconscious Mind Rules Your Behavior explains that the vast majority of our brain’s processing happens beneath the surface of awareness. This hidden mental activity shapes how we interpret our observations, form beliefs, and experience the world around us. Keep reading for an overview of this thought-provoking book.

An Insight Mindset: How Uncertainty Leads to Breakthroughs

What does it take to have breakthrough ideas and moments of clarity? How can we train ourselves to welcome the unexpected insights that lead to innovation rather than resisting them? In his book Seeing What Others Don’t, Gary Klein reveals that developing an insight mindset begins with embracing uncertainty. His research shows that the most innovative thinkers approach problems with curiosity and openness, viewing contradictions as valuable learning opportunities. Keep reading to discover how developing an insight mindset can transform your life and work.

Reading in the Digital Age Is Altering Our Brains (Maryanne Wolf)

Is our relationship with reading fundamentally changing as we move from traditional to digital formats? What does this shift mean for our cognitive abilities and future intellectual development? Reading in the digital age represents a significant transformation in how our brains process information. Cognitive neuroscientist Maryanne Wolf explains that our current shift to digital reading is rewiring our neural pathways in ways that bring both opportunities and risks. Keep reading to discover how screens are changing not just what we read but how we think—and what we can do to preserve the valuable cognitive skills traditional reading has given us.

What Is Planned Obsolescence? Biotech Researcher Explains

What Is Planned Obsolescence? Biotech Researcher Explains

Are human bodies hardwired to break down as they age? What is planned obsolescence? In his book Jellyfish Age Backwards, Nicklas Brendborg discusses two scientific theories that explain why humans age in the way that they do; one of those theories is planned obsolescence. Essentially, this theory states that aging is programmed into our genes. Keep reading for a deeper look into this fascinating theory.

Memory Distortion: Why Memories Are Dynamic Reconstructions

How much of what you remember actually happened? What invisible forces reshape your recollections each time you access them? Our brains don’t record memories like video cameras. Instead, they act more like storytellers, reconstructing events in ways that serve us but don’t always reflect reality. In his book Subliminal, Leonard Mlodinow reveals how memory distortion follows predictable patterns. Keep reading to discover why even your most vivid memories might be less reliable than you think.

The Disadvantages of Digital Reading & Ways to Minimize Them

What happens to our brains when we read on screens versus paper? How can we balance digital convenience with deeper comprehension skills? In her book Proust and the Squid, Maryanne Wolf explores the significant disadvantages of digital reading alongside its benefits. She explains how our brains adapt differently to online reading, with platforms encouraging skimming rather than deep reading. Below, find Wolf’s practical strategies for parents, teachers, and readers to maintain deep reading abilities while still embracing the digital world.

What effects does music have on the brain? How can music be used as a form of medicine? In I Heard There Was a Secret Chord, award-winning neuroscientist and musician Daniel J. Levitin discusses music’s history and potential as a form of medicine. Drawing from scientific research, he demonstrates how music therapy can effectively treat conditions ranging from Parkinson’s to chronic pain. Continue reading for a fascinating deep dive into the neuroscience of music.

Julian Jaynes: The Origin of Consciousness (Overview)

Have you ever wondered why humans naturally gravitate toward religious beliefs? What if our modern way of cognition and experience emerged only a few thousand years ago? Julian Jaynes’s The Origin of Consciousness in the Breakdown of the Bicameral Mind proposes that consciousness as we know it today didn’t always exist. Jaynes suggests humans once operated with a “bicameral mind,” where one part of the mind issued commands that the other part followed. Keep reading to discover how Jaynes’s controversial theory might explain religious tendencies, sudden civilization development, and even our struggles with decision-making.

Examples of Insights: How Some People Saw What Others Didn’t
