How curiosity rewires your brain for change

A few years ago, I decided to retrain as a neuroscientist. It was a leap into the unknown — no roadmap, just a desire to grow. I chose to approach this time of change with curiosity, and I started a weekly newsletter to document what I learned. Suddenly, my doubts became fuel for discovery.

What I didn’t know at the time was that this systematic curiosity was actively reshaping my brain in ways that would build resilience for navigating future changes.

Curiosity is often treated as a personality quirk — something childlike and playful, maybe even optional. But neuroscience paints a different picture. When we’re curious, the brain’s dopaminergic system — the same one that lights up when we anticipate a reward — kicks into gear. Simply put, curiosity makes us feel good about the prospect of discovering something new.

It also helps us learn more efficiently, enhancing hippocampal activity and boosting our capacity to form and retain new memories. Studies show that when people are curious about a topic, they not only remember the specific information they were interested in but also retain unrelated material better.

Perhaps most importantly, curiosity promotes neuroplasticity, the brain’s ability to rewire itself in response to new experiences. This makes it an ideal cognitive state for those inevitable moments of change when we need to break established neural patterns and form new connections.

Curiosity in times of change

Change, by nature, introduces uncertainty. And the human brain typically responds to uncertainty by activating the amygdala, triggering the same stress responses as physical danger.

What curiosity does is transform that uncertainty from a threat into an invitation.

First, curiosity increases our tolerance for prediction error: the gap between what we expect and what we actually experience. This makes us more flexible in our thinking, less reactive, and better at updating our mental models.

There’s also a balancing act happening between two major brain networks: The default mode network (associated with imagination and introspection) and the executive control network (responsible for goal-oriented behavior) often take turns.

Curiosity helps synchronize these networks, allowing us to envision possibilities while also taking action — the exact balance needed to navigate change.

Emotionally, curiosity can also act as a buffer. When we view an unexpected situation through a curious lens (“what can I learn from this?”), we are less likely to spiral into anxiety or avoidance. This cognitive reframe can dramatically alter how we experience the inherent uncertainty of change.

5 ways to navigate change with curiosity

Curiosity isn’t a fixed trait you either have or lack — it’s a cognitive skill that can be developed. Here are five ways to cultivate it, especially during times of change:

1. Ask “what if?” instead of “what now?”

Reframe fear-based responses with questions that invite exploration. Instead of “I don’t know how to handle this new role,” try “What if I approached this role as a learning opportunity?” This simple shift activates your prefrontal cortex rather than your amygdala, which will help minimize stress in times of change.

The Sun May Be Entering an Era of Stronger 11-Year Cycles

2 Comments

.

A year ago this weekend, the sun’s activity created some of the most spectacular auroras on record, with displays visible as far south as Florida.

The incredible spectacles last May (and another auroral outburst last October) were partly a matter of luck because several factors, some of them serendipitous, affect the appearance of aurora. But the sun had been primed to put on a show as it approached the maximum phase of its 11-year activity cycle—and that high activity continues today. This solar cycle still has the potential to cause more celestial spectacles before activity calms down. And scientists say that the coming solar cycles may be even more eventful. But it remains quite difficult to predict the sun’s behavior.

“Solar storms—it’s a probabilistic thing, so sometimes they don’t always do what you would expect,” says Lisa Upton, a heliophysicist at the Southwest Research Institute.

The Sun Right Now

The sun is essentially a massive liquid magnet. Heliophysicists gauge our star’s activity by tallying the number of sunspots—relatively “cold” knots of its magnetic field that are often the source of radiation and plasma outbursts—on its surface. (Scientists monitor this tally in real time, but they evaluate the solar cycle’s stages based on smoothed averages over many months. So the formal declaration of a cycle’s solar maximum and minimum always happens after the fact.)

The number of sunspots naturally rises and falls over about 11 years, during which the sun’s magnetic poles first strengthen, then weaken and finally flip. When the sun’s magnetic field is calmest, with one pole that is firmly positive and one that is firmly negative, activity is at its minimum, as it was most recently around December 2019, and the star is sometimes entirely free of blemishes.

For more than a year now, the sun has been in the opposite phase—the solar maximum—with a messy magnetic field, plenty of sunspots and regular outbursts. August 2024 produced the most sunspots of any recent month, with more than 200 such storms.

Sunspots have since become less numerous, but it’s still unclear whether the solar maximum is truly on its way out. “We’ve had a little bit of a slowdown in activity [during] the last couple months. That’s not too surprising,” Upton says. “A question at this point, which will be interesting, is whether or not we’re going to have another little spike in activity.”

She says that if such a spike were to happen, it would likely come within about three months, mirroring a small spike that occurred in June and July 2023. “But the sun likes to surprise us,” Upton adds, “so we’ll see if that happens.”

Long-Term Cycles

Even as scientists watch the current solar cycle unfold, they’re also working to understand what future cycles might bring.

That’s a difficult task, given that modern science is only in the 25th activity cycle, in which researchers have made plentiful sunspot observations. More sophisticated observations that help scientists understand the sun in detail, such as space-based observations and magnetic data, are even newer, with some offering insight into only a couple of solar cycles thus far. Scientists can study tree rings and ice cores to get a basic sense of solar activity before observations began, but these data are less detailed and don’t provide precise sunspot counts.

One hypothesis suggests that the sun displays a longer-term variability called the Gleissberg cycle, named for astronomer Wolfgang Gleissberg, who posited such 80-year cycles in the 1960s. (Other proposed longer-duration cycles in solar behavior include the Suess–de Vries cycle, lasting 195 to 235 years, and the Hallstatt cycle, stretching over some 2,400 years.) And a new analysis of protons trapped in the inner radiation belt that surrounds Earth suggests a new Gleissberg cycle may be beginning.

Not all heliophysicists are sold on the Gleissberg cycle, however, given the scant data scientists have to work with. “It’s kind of debatable whether or not this is a physical phenomenon versus a statistical phenomenon,” Upton says.

The dark side of ambition

Leave a comment

.

Ambition is one of the most defining forces in human affairs—a psychological engine that propels individuals beyond the realm of survival into the arena of creation, disruption, and transformation, and significantly predicts educational attainment, career success, job performance, and income.

At its core, ambition is the refusal to accept the status quo, the internal pressure to stretch personal limits and societal boundaries. In a way, the best way to understand ambition is as the inability to be satisfied with one’s accomplishments. Ambition fuels leadership by pushing individuals to take responsibility, imagine alternatives, and mobilize others toward a vision. Ambition underwrites entrepreneurship as the catalyst for risk-taking, persistence, and the stubborn belief that a better way is not only possible but necessary. Without ambition, innovation stalls; with it, people challenge orthodoxy, break conventions, and solve problems that others resign to fate. Across disciplines, from science to art to politics, history’s breakthroughs are seldom the product of complacency—they are the residue of restless, ambitious minds.

The world, to a large extent, is the output of ambitious people. It is shaped by those who couldn’t sit still, who weren’t content with inherited limitations, and who felt compelled to act on their ideas, no matter how unlikely or unpopular. From the first controlled fire to the latest generative AI models, progress has never been evenly distributed—it has been driven by individuals and groups with an outsized appetite to leave a mark. Ambition transforms dissatisfaction into momentum, and imagination into infrastructure. It explains not just who rises to lead or invent, but why civilizations expand, technologies leap forward, and cultures evolve. While it must be tempered by ethics and collective concern, ambition remains an irreplaceable force in the story of human progress.

Everything in moderation

And yet, like all powerful traits, ambition is best expressed in moderation. Too little, and individuals drift—untethered from purpose, passive in the face of opportunity. Too much, and ambition can metastasize into obsession, crowding out humility, collaboration, and even moral judgment. When ambition becomes unbounded, it stops serving the individual and begins demanding sacrifice of relationships, values, and long-term well-being. It can distort self-perception, encouraging people to see themselves not as contributors to a shared cause, but as lone heroes in a zero-sum contest. Teams suffer when ambition eclipses empathy: the pursuit of personal achievement starts to undermine trust, cooperation, and psychological safety. A competitive drive that ignores others’ needs doesn’t just alienate colleagues—it weakens the very foundation of high-functioning organizations.

Unchecked ambition often bleeds into greed, an insatiable hunger not just to succeed, but to dominate. As Gordon Gekko infamously said, “Greed is good”—a provocative mantra for the high-octane world of finance, but a dangerous philosophy when applied indiscriminately. Greed erodes the social contract. It justifies exploitation, tolerates unethical shortcuts, and treats people as a means to an end. In leadership, this can result in toxic cultures, short-term thinking, and spectacular failures. Companies driven solely by ambition without constraint may grow fast, but they often implode faster, toppling under the weight of hubris, burnout, and scandal.

The WeWork Case

Adam Neumann, cofounder and former CEO of WeWork, is a textbook example of how unbridled ambition can lead to spectacular collapse. Neumann started with a compelling vision: to “elevate the world’s consciousness” through a coworking space company that promised to redefine the way people live and work. His charisma and relentless ambition helped WeWork grow at breakneck speed, attracting billions in venture capital and inflating its valuation to nearly $47 billion at its peak. But Neumann’s ambition quickly outpaced operational reality. He expanded into housing (WeLive), education (WeGrow), and other ventures with little strategic coherence. Reports surfaced of erratic behavior, conflicts of interest, and a corporate culture driven more by Neumann’s personal mythos than sound governance.

In 2019, when WeWork attempted to go public, its financial inconsistencies and Neumann’s questionable leadership style came under scrutiny. The IPO failed, Neumann was forced to resign, and the company’s valuation plummeted. His ambition wasn’t the problem in itself—it was that it became delusional, detached from execution, and ultimately corrosive to the company’s sustainability. Neumann exemplifies how visionary drive, without discipline or humility, can become a liability rather than an asset.

In short, the healthiest ambition is grounded in purpose, tempered by self-awareness, and balanced by a commitment to collective success. It lifts everyone, not just the one climbing the fastest.

So, while it’s generally better to have than to lack ambition, here are three proven ways in which an excess of drive or motivation can harm your career and negatively impact others.

1. Ambition can inhibit people’s prosocial drive

When the desire to “get ahead” outweighs the instinct to “get along,” ambition can corrode social cohesion. In team environments, overly ambitious individuals may hoard credit, prioritize visibility over contribution, and treat colleagues as competitors rather than collaborators. This undermines trust and psychological safety—two bedrocks of effective teamwork. For example, a rising executive who constantly angles for the spotlight may alienate peers and demoralize subordinates, even if their individual output is impressive. Over time, the cost of such interpersonal friction outweighs the benefits of raw performance. In the long run, organizations thrive not on lone stars but on networks of mutual respect and cooperation, both of which ambition can quietly erode if left unchecked.

Today’s Children Face a Lifetime of Extreme Heat because of Climate Change

Leave a comment

.

Just over half of the children born in 2020 will face unprecedented exposure to heatwaves over their lifetime, even under a conservative projection for how climate change will unfold over the next 75 years.

The figure rises to 92% of today’s five-year-olds if more pessimistic climate predictions come to pass, and compares with just 16% of people born in 1960 under any future climate scenario.

The findings, published in Nature on 7 May, highlight the disproportionate burden that climate change places on today’s young people — and the need to limit global warming to safeguard future generations.

“Many people of my age have children, young children, and it’s especially for those that the projections look very dire,” says study co-author Wim Thiery, a climate scientist at the Vrije Universiteit in Brussels, who was born in 1987.

That children and young people will bear the brunt of the climate-change burden is not a new idea. But the latest study is among the first to pinpoint the generations and numbers of people that will experience an “unprecedented life” in terms of extreme heat, says Thiery (see ‘Children facing extreme heat’).

They then used demographic data to calculate, for a series of generations born between 1960 and 2020, worldwide, the fraction of each generation that would reach that limit across their lifetimes — and how that would vary with different global-warming scenarios.

Heat on the horizon

The proportion of each generation predicted to experience ‘unprecedented lives’ in terms of heat exposure varied hugely. Of the 81 million people born worldwide in 1960, who are now in their mid-sixties, just 13 million, or 16%, would reach this exposure threshold over their lifetimes, regardless of the climate scenario. But for the 120 million children born in 2020, 58 million (around 50%) would experience this level of exposure, even in the most optimistic scenario put forward by researchers of 1.5 °C of warming above pre-industrial temperatures by 2100. The fraction of today’s five-year-olds experiencing unprecedented lifetime exposure to heatwaves rises to 92% (some 111 million people) for the more pessimistic climate scenario of 3.5 °C of warming.

A millennial who couldn’t find a job for 4 years revamped his family’s meal planning and childcare to make it work

.

For one, they bought a deep freezer, which allowed them to buy in bulk and freeze meals that Colflesh cooked in large batches — a purchase he believes will save them money in the long run. ​​They also grew some of their own produce in a vegetable garden and smoke-cured store-bought bacon at home to cut grocery costs. Additionally, the family decided to stop using one of their two vehicles and dropped the insurance on it — a choice that was feasible because Colflesh wasn’t commuting to work.

Colflesh added that YouTube videos helped him handle basic car maintenance himself, so he could save money on mechanic bills. And because he was home more, he was able to help care for his children, which reduced his family’s childcare expenses. Colflesh said taking these steps helped him feel less pressure during his job search.

A positive mindset helped him persevere

In 2015, when he was 34, Colflesh quit his job in the customer service industry to pursue a college degree, hoping it would help him with career growth. Six years later, he held an associate degree in physics from Holyoke Community College in Massachusetts and a bachelor’s in political science from the University of Massachusetts Amherst.

But Colflesh said the additional education didn’t seem to help him much in the job market and saddled him with student loans. Despite applying to more than 100 jobs, he struggled to find work, he said, which led him to pause his search for a few months at a time.

Colflesh said he tried common job search strategies, such as tailoring his résumé and cover letter to each role, but nothing seemed to work. Then, last year, a friend referred him for a job at a tech company that would involve answering phones, scheduling, and triaging customer support tickets. He said the referral helped him land an interview, and by May 2024, he’d accepted a job offer.

“This isn’t really what I was looking for, but it’s far from the worst job I’ve had,” he said.

During his job search, Colflesh managed stress by hanging out with friends, engaging with his hobbies, and spending time with his family. While he felt discouraged at times, he did his best to retain a positive mindset, which he said was key to staying motivated.

“Staying positive has to be a choice the person makes,” he said. “Waiting for the situation to create positivity will likely cause you to feel unmotivated and upset. You keep moving forward because what other option is there?”
