Over the last few years,
sustainability has become one of the biggest buzzwords in the fight against environmental problems like climate change, loss of biodiversity, ecosystem degradation, and pollution. But what does sustainability actually mean? And how do you make it part of your everyday life?
Broadly speaking, sustainability is the idea that we must meet our own needs
without compromising the ability of others to meet their needs, whether the “others” in question are future generations or people living in other parts of the world. But understanding the basic concept is one thing. Practicing it is quite another.
Every single day we make dozens of different choices that impact our planet. But understanding this impact is not easy. And when it comes to green living, there is a lot of conflicting information about what’s eco-friendly, what’s not, what’s fact, and what’s fiction.
But green sustainable living is possible. With a little guidance, we can all learn to make better choices for ourselves and the planet.
And that’s where the Sustainable Living Online Course from International Open Academy comes in.

A safe, stable home can change lives for the better. Here’s how Habitat for Humanity wants to make that possible for everyone.
Better health, better jobs, and a brighter future all start with access to a safe, affordable home.
A single door can open up a world of endless possibilities. For homeowners, the front door of their house is a gateway to financial stability, job security, and better health. Yet for many, that door remains closed. Due to the rising costs of housing, 1 in 3 people around the world wake up without the security of safe, affordable housing.
Since 1976, Habitat for Humanity has made it their mission to unlock and open the door to opportunity for families everywhere, and their efforts have paid off in a big way. Through their work over the past 50 years, more than 65 million people have gained access to new or improved housing, and the movement continues to gain momentum. Since 2011 alone, Habitat for Humanity has expanded access to affordable housing by a hundredfold.
A world where everyone has access to a decent home is becoming a reality, but there’s still much to do. As they celebrate 50 years of building, Habitat for Humanity is inviting people of all backgrounds and talents to be part of what comes next through Let’s Open the Door, a global campaign that builds on this momentum and encourages people everywhere to help expand access to safe, affordable housing for those who need it most. Here’s how the foundation to a better world starts with housing, and how everyone can pitch in to make it happen.

Volunteers raise a wall for the framework of a new home during the first day of building at Habitat for Humanity’s 2025 Carter Work Project. Globally, almost 3 billion people, including 1 in 6 U.S. families, struggle with high costs and other challenges related to housing. A crisis in itself, this also creates larger problems that affect families and communities in unexpected ways. People who lack affordable, stable housing are also more likely to experience financial hardship in other areas of their lives, since a larger share of their income often goes toward rent, utilities, and frequent moves. They are also more likely to experience health problems due to chronic stress or environmental factors, such as mold. Housing insecurity also goes hand-in-hand with unstable employment, since people may need to move further from their jobs or switch jobs altogether to offset the cost of housing.
Affordable homeownership creates a stable foundation for families to thrive, reducing stress and increasing the likelihood for good health and stable employment. Habitat for Humanity builds and repairs homes with individual families, but it also strengthens entire communities as well. The MicroBuild® Initiative, for example, strengthens communities by increasing access to loans for low-income families seeking to build or repair their homes. Habitat ReStore locations provide affordable appliances and building materials to local communities, in addition to creating job and volunteer opportunities that support neighborhood growth.

Marsha and her son pose for a photo while building their future home with Southern Crescent Habitat for Humanity in Georgia. Everyone can play a part in the fight for housing equity and the pursuit of a better world. Over the past 50 years, Habitat for Humanity has become a leader in global housing thanks to an engaged network of volunteers—but you don’t need to be skilled with a hammer to make a meaningful impact. Building an equitable future means calling on a wide range of people and talents.
Here’s how you can get involved in the global housing movement:- Speaking up on social media about the growing housing crisis
- Volunteering on a Habitat for Humanity build in your local community
- Travel and build with Habitat in the U.S. or in one of 60+ countries where we work around the globe
- Join the Let’s Open the Door movement and, when you donate, you can create your own personalized door
- Shop or donate at your local Habitat ReStore
Every action, big and small, drives a global movement toward a better future. A safe home unlocks opportunity for families and communities alike, but it’s volunteers and other supporters, working together with a shared vision, who can open the door for everyone.

Why don’t space photos ever show stars? NASA’s explanation is simpler than you’d think and a photo from Artemis II proves it.
It comes down to basic camera science. The same rules that apply to your phone apply to cameras 400,000 kilometers from Earth.
Every time NASA releases a stunning image from space of something like the Earth glowing against blackness, or the Moon’s cratered surface in sharp detail, the same question follows: where are the stars?
It happened again when NASA’s Artemis II crew, which launched April 1, 2026 and flew around the Moon before splashing down in the Pacific on April 10, began beaming back photos from their historic 10-day mission. The images were breathtaking. The backgrounds were pitch black. And the conspiracy theories started almost immediately.
The camera can only do so much
NASA’s answer, as explained in an Instagram post, is straightforward: it’s just how cameras work.
A camera captures a limited range between the brightest and darkest parts of a scene. When you’re photographing the Moon or the Earth from space, you’re dealing with an enormous difference in brightness. The sunlit surface of the Moon is extraordinarily bright, while stars are extraordinarily dim. To expose correctly for the bright object in the foreground, the camera’s settings have to be adjusted in a way that makes the faint stars in the background vanish into black.
Three settings control this. Shutter speed determines how long the camera’s sensor is exposed to light. ISO controls how sensitive that sensor is to light. And aperture determines how wide the lens opens. Getting the Moon in sharp, detailed focus means tuning all three for brightness, which is the opposite of what you’d need to pick up the faint glow of distant stars. You could technically try to capture both, but the result would be a blurry, overexposed mess where neither looks right.
The same thing happens on Earth. Try taking a photo of the night sky next to a bright streetlight. The stars disappear. The light itself isn’t unusual. It’s physics.
The photo that proves both sides
The most remarkable image from the Artemis II mission accidentally became the perfect illustration of exactly this phenomenon. On April 6, during their seven-hour flyby of the Moon’s far side, the crew captured a total solar eclipse. The Moon completely blocked the Sun for nearly 54 minutes of totality, far longer than any eclipse visible from Earth’s surface.
In that image, stars are clearly visible. Dozens of them, scattered across the frame around the dark disk of the Moon with its glowing halo of light. Venus appears as a bright silver glint on the edge. It’s one of the most striking photographs ever taken by humans in deep space.
The reason the stars appear is the same reason they normally don’t: the object in the foreground is dark. With the Moon blocking the Sun, there’s no blinding bright surface to expose for. The camera settings could be adjusted to capture the dim light of distant stars, and they showed up exactly as they should.
As NASA noted in the image description, stars are “typically too faint to see when imaging the Moon, but with the Moon in darkness stars are readily imaged.”
A historic mission
The Artemis II mission marked humanity’s return to the Moon’s vicinity for the first time since Apollo 17 in 1972. The crew included commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen of the Canadian Space Agency. They set multiple records. Koch became the first woman to travel beyond low Earth orbit. Glover became the first person of color to witness the lunar far side. Hansen became the first person from a nation other than the United States to go to the Moon. And the mission broke the all-time crewed distance record, reaching 406,771 kilometers from Earth, surpassing the mark set by Apollo 13 in 1970.
The crew also captured an Earthset, with Earth sinking below the Moon’s horizon, that deliberately echoed the iconic Earthrise photo from Apollo 8 in 1968. They photographed ancient lava flows, impact craters, and surface fractures on the far side. They witnessed six meteoroid impact flashes on the darkened lunar surface.
Koch described the experience with characteristic simplicity: “The Moon really is its own unique body in the Universe. It’s not just a poster in the sky that goes by. It’s a real place.”
And it turns out space is full of stars. You just need the right conditions and the right camera settings to see them.

His mysterious toe pain lasted five years. The scan that finally caught it gave him four days to live.
“If my whole leg hadn’t swollen up, I would have dropped dead.”
Richard Bernstein walked around barefoot a lot at home, so when his right toe started hurting in 2017, he assumed he’d stubbed it. A visit to his podiatrist confirmed nothing was broken and nothing was wrong. He moved on.
But the pain didn’t.
Five years of pain that no one could explain
Over the next few years it crept upward from his toe to his ankle, then to his knee. A sports medicine doctor suggested stenosis and recommended physical therapy. That didn’t help either. Walking became gradually harder. On a trip to Greece, Bernstein had to sit out while his friends climbed to hilltop monasteries. He took his dog to the park less and less.
In March 2022, his right leg swelled noticeably. His doctor ordered an abdominal scan. What it found changed everything.
What they found when they finally looked
Bernstein had a massive cancerous kidney tumor that had grown into his vena cava, the main vein that returns blood from the lower body to the heart. The tumor and tumor thrombus were a foot long and weighed around two and a half pounds. Because the vena cava was almost completely blocked, blood was backing up in his lower extremities, which explained the years of unexplained pain creeping up his right side. His two main coronary arteries had also been compromised, with 99 percent of their function lost.
He was referred to Dr. Michael Grasso, chair of urology at Phelps Hospital. Grasso’s assessment was direct. “He told me I had four days to live,” Bernstein said.
A 12-hour surgery, three specialists, one chance
The surgery required three specialists working simultaneously over 12 hours at Lenox Hill Hospital in New York City. Dr. Grasso handled the kidney and tumor removal. Cardiothoracic surgeon Dr. Jonathan Hemli performed a double bypass on the coronary arteries, which had been discovered only once Bernstein was already admitted, an unexpected complication that Hemli said they couldn’t ignore. “It would have been really disappointing to cure him of his kidney cancer only to learn in six months, nine months, a year that the poor man had a heart attack and didn’t survive,” Hemli told TODAY. Vascular surgeon Dr. Alfio Carroccio opened the vena cava to remove the tumor thrombus, which extended all the way into the heart.
To do the work safely, the team had to cool Bernstein’s body, stop his heart, and run him on a heart-lung bypass machine while they operated. Then they slowly warmed him back up and restarted his heart.
Bernstein spent three days sedated afterward, a week in intensive care, and nearly three weeks in cardiac rehab relearning to walk. He lost around 30 pounds. He gained it back.
He’s now on ongoing immunotherapy and doing twice-yearly scans. Dr. Grasso’s update: “The cancer hasn’t spread anywhere else, which is amazing, considering where he came from.”
Bernstein’s own assessment of how he got through it: “My attitude is ‘it is what it is, and there’s not much we can do about it.’ That got me through.” His advice for anyone else in a similar situation: “If something is wrong and they can’t find it, don’t give up looking. Trust your feelings about your own body.”
And on the swollen leg that finally triggered the scan that saved him: “If my whole leg hadn’t swollen up, I would have dropped dead.”

Investigative journalist reveals the simple way you can protect your phone from getting hacked
His simple tip can offer protection in a time of less-than-stellar privacy regulations.
There are just so many ways for important information held on your phone to be swiped—from subscription based apps that secretly send private customer data to Facebook to fake accounts that get your friends to invest in some kind of fake crypto.
And of course—this is more than a modern day inconvenience. It poses real threats to democracy and global human rights, which is why so many are calling for more regulations and safeguards. Of course, as with most regulations, change isn’t coming fast. Which isn’t good news, considering how rapidly technology evolves.
However, Pulitzer Prize winning investigative journalist Ronan Farrow has an incredibly simple tip for preventing our phones from being hacked: Turn them off more often.
Why Ronan Farrow says we should all be ‘freaking out’
While appearing on the Daily Show to promote his new documentary, Surveilled, Farrow told host Desi Lydic that we as a society should be “freaking out” more about the lack of government restraints about spyware technology, saying that it could turn the country “into an Orwellian surveillance state,” affecting anyone who uses a device, essentially—not just political dissidents.
But, as Farrow noted, turning your phone off and on every day is an easy way to protect yourself, since most current forms of spyware “will be foiled by a reboot.” And even if you aren’t, say, a journalist or a political activist (i.e. common targets for malware), you’re thwarting apps from monitoring your activity or collecting your data. And better still, you’re making it more difficult for hackers to steal information from your phone. Privacy protection aside, it’s a great way of just keeping your device healthy. Basically, it seems like the age-old solution for virtually all tech issues still holds up.
More easy steps you can take right now

Remembering to turn it off…that’s a different challenge altogether. Photo credit: Canva There are a few other things worth turning off now and then, such as bluetooth and location devices when you’re not using them, according to the NSA. In addition, Farrow also suggested keeping devices updated, and perhaps most important of all, actually writing to your representative about the issue.
However, when it comes to wrapping devices in tinfoil as a makeshift Faraday cage…that might not be the best use of one’s aluminum.
“Experts vary on exactly how effective that approach is,” Farrow told Lydic, just before quipping, “we need better policies. Not just better tinfoil.”
The documentary that started it all
Expanding on Farrow’s 2022 New Yorker investagative exposé on the notorious spyware Pegasus, Surveilled, which is available to stream on Max, delves into the multibillion-dollar industry of commercial spyware and its potential threats, making it evidently clear that this is not an issue for the elite few, or one to ignore until the future.
On a (slightly) brighter note, Farrow debuted another new work in 2025, this time a true crime investigative podcast, titled Not a Very Good Murderer, which he himself narrates. Find it on Audible.

New small talk study reveals why you should never fear a boring conversation
Even a micro-conversation can help reduce anxiety.
“Job treating you alright?” “Looks like this weekend is gonna be a real scorcher.” “That Cowboys game was outrageous.” These are some conversational snippets one might hear that could lead to immediate panic—that insufferable “small talk” lies ahead. But new research published in the Journal of Personality and Social Psychology claims that people actually like, and often benefit from, these kinds of conversations.
Researchers discovered that even though people reported not looking forward to “boring” conversations, a majority found them quite fun.
Even “boring” topics were fun
The team mixed and matched respondents to cover all bases. In one experiment, they observed conversations in which “one person finds the topic boring.” In another experiment, they created a situation where both participants “find the topic boring.” They also tested groups based on whether the participants were strangers or friends.
In a piece published by the American Psychological Association (APA), researchers reported that, after studying 1,800 participants, “people consistently underestimated how interesting and enjoyable conversations about boring topics would be.”
Some might question what topics are considered (potentially) “boring” in the first place:
“Topics were many and varied, including World Wars I and II, nonfiction books, the stock market, cats, and vegan diets. In some cases, participants were asked to suggest a topic they found boring (responses included such topics as math, onions and Pokemon).”
Elizabeth Trinh, a doctoral student at the University of Michigan and lead author of the study, said she was excited about the results.
“We were both surprised and excited by how robust the effect was,” she said. “People consistently expected conversations about seemingly boring topics to be less interesting than they turned out to be.”
“Serves a real purpose”
Upworthy spoke with licensed therapist Rebecca Tenzer, owner of Astute Counseling and Wellness Center. She explained why many of us feel anxious about so-called small talk, only to find it entertaining.
“While it gets dismissed a lot, small talk actually serves a real purpose when it comes to mental health,” Tenzer said. “These smaller, everyday interactions help people feel connected, acknowledged, important, and can even build self-esteem. Even if the conversation is simple or surface-level, there are meaningful impacts and a lot of gain.”
Tenzer also supported the idea that these micro-conversations, no matter the topic, have significant benefits.
“We’re seeing more evidence that even brief social exchanges can improve mood, teach social norms, and reduce feelings of loneliness,” she said. “Along with those interactions are often positive body language exchanges, smiles, and even laughter, all of which are happiness chemical hacks needed to boost mood.”
“Small talk acts as a low-pressure way to engage with others, which can help regulate the nervous system and make social interaction feel easier over time,” Tenzer added. “Not every conversation needs to be deep to have value. It’s nice to force yourself to slow down, take a minute to chit-chat, be in the moment, and stay present. It’s not a huge time commitment and often has lasting benefits throughout the day.”
“Predictable, consistent, and not threatening”
Lisa Chen, a licensed psychotherapist, concurred, telling Upworthy that these types of conversations can help put people at ease, even if they might not expect it.
“As a psychotherapist who works with high-achieving, often socially guarded clients, I see how ‘low-stakes’ interactions create a sense of safety in the body,” she said. “Even brief exchanges like saying ‘hello’ to the barista making your coffee or making casual conversation at work help remind our nervous system that the world is predictable, consistent, and not threatening.”
Chen says small talk can help lower anxiety.
“It lowers social anxiety over time, builds relational confidence, and gently reinforces that we belong in shared spaces,” she said. “But small talk isn’t just for those who struggle with social anxiety. It’s for everyone. Small talk strengthens our sense of belonging, improves our mood, and keeps us from becoming too transactional or isolated from others. It also softens intensity and creates moments of ease that prevent stress and burnout.”

Want a team that performs well under pressure? Include a ‘clown,’ says NASA.
Humor is an underrated team-building quality.
We know that collectively performing under pressure requires some special qualities, but what are they? That’s the question NASA seeks to answer as it looks ahead to sending humans to Mars. When it comes to team dynamics, a small crew on a 10-day stint around the moon is one thing. A team stuck on a spaceship for months and living together on a planet two million miles from home is another.
NASA’s Human Research Program studies human behavior in teams to analyze the implications of long-duration space missions. After observing team dynamics and roles in groups in various studies, one delightful conclusion can be drawn.
Every team needs a clown.
According to NASA, astronauts have returned from stints on the International Space Station and reported that humor played a critical role in diffusing tension between people working on the I.S.S. The same finding has come from research studies in analog environments. (Analogs are places like Antarctica, where the desolate and extreme environment somewhat mimics a place like Mars.)
“You need a clown on the team,” said Noshir Contractor, Ph.D., professor of behavioral sciences at Northwestern University. In other words, you need someone who can make their teammates laugh.
Contractor is conducting a study titled Crew Recommender for Effective Work in Space (CREWS). Using research data from an analog study, her team is developing a computer model to help select the best individuals to form a crew.
“We don’t have a perception that we’re going to tell them who to send on a mission,” Contractor said, according to NASA. “But if they have a collection of people, it will work like a weather forecast model. It’s a predictive model that says if you choose this particular crew, here is what you are likely to see in terms of team dynamics. And, if problems arise, here is how to intervene to ease those problems.”
Easing problems is one place where the clown plays an important role. Research shows that positive humor can increase communication and social support and create a pleasant environment. Most of us have experienced how a well-timed joke or witty response can stop tension in its tracks.
Tension often manifests physically. We feel it in our bodies when emotional stress is high. According to the Mayo Clinic, laughter can stimulate circulation and help muscles relax, easing some of the physical symptoms of stress. Laughter also releases endorphins that make us feel good and promote social bonding.
What about teams that aren’t in as extreme circumstances as going on a mission to Mars or wintering in Antarctica? Dr. Adil Dalal of the Forbes Coaches Council says humor has a “transformative power” that unlocks the ability to do serious work well in the professional world.

Photo credit: Canva – Laughing with your colleagues may help improve team performance. “When we laugh, cortisol, the stress hormone that can narrow thinking and trigger defensive behavior, drops significantly,” writes Dalal. “Laughter also causes the release of dopamine, oxytocin and endorphins, which are associated with motivation and learning. In the workplace, this means that laughter can encourage new behaviors and insights. It can also strengthen trust, which is essential for psychological safety and sustained high performance among employees.”
So if you’re leading a team or part of a team that appears to be struggling, perhaps some clowning around is in order. As Dr. Dalal writes, “Fun is not the opposite of seriousness—it is the pathway to sustainable excellence.”
If NASA touts the vital role humor plays in teamwork and success, perhaps we all ought to give it a little more weight in our own teams.
