The dangers of smoking aren’t new—but emerging research is now pointing to a shocking link between heavy smoking and unexplained strokes in younger adults, especially men aged 45 to 49. A new study, published in the February issue of Neurology Open Access, suggests that smoking may be a hidden culprit behind cryptogenic strokes—strokes with no known cause—that strike seemingly healthy individuals long before their senior years. The study does not mention if cannabis smoking is also a factor.
What Is a Cryptogenic Stroke?
A cryptogenic stroke is a type of ischemic stroke, which occurs when a blockage disrupts blood flow to the brain. But here’s the catch: unlike typical strokes, the cause of these blockages remains a mystery. The symptoms—weakness, trouble speaking, and vision problems—can be devastating. While most strokes happen after age 65, researchers are now seeing an increase in younger people with these unexplained strokes.
“While smoking has long been linked to ischemic stroke, little is known about how smoking affects people under 50, especially in those with unexplained stroke,” said Phillip Ferdinand, MBChB MRCP, of Keele University in the UK and a member of the American Academy of Neurology. “Recent research has shown an increase in younger people having these unexplained strokes, so it is important to evaluate any potential links. Our study found that smoking may be a key factor.”
To investigate, researchers analyzed 546 people aged 18 to 49 who had suffered an unexplained stroke, comparing them with 546 people of the same age and sex who had not. Participants answered questions about smoking habits, alcohol use, education level, physical activity, and other health conditions.
The Numbers Speak for Themselves
Among those who had an unexplained stroke, 33% were smokers, compared to just 15% in the control group.
Even after adjusting for other stroke risk factors like alcohol use and blood pressure, researchers found that smokers had more than double the risk of unexplained stroke compared to non-smokers.
The risk was highest for men, who had more than three times the risk.
The danger spiked for people ages 45 to 49, who had nearly four times the risk.
Heavy smoking—defined as more than 20 packs a year—led to an even greater risk:
Heavy smokers faced a fourfold increase in unexplained stroke risk.
Male heavy smokers saw nearly seven times the risk.
Smokers aged 45 to 49 had nearly five times the risk.
Public Health Implications: Smoking Prevention Matters
Women smoke too and shisha pipes may be worse because they have no filters
The findings reinforce the need for stronger public health initiatives aimed at preventing smoking, especially heavy smoking, in younger adults. “Our findings suggest that continued public health efforts around preventing smoking, especially heavy smoking, may be an important way to help reduce the number of strokes happening to young people,” said Ferdinand.
The study’s findings were primarily based on people of white European backgrounds, so additional research is needed to see if the results apply to other populations. However, the message is clear: quitting smoking, or better yet—never starting—could be a critical step in stroke prevention.
If you or someone you know smokes, consider this study another urgent reason to quit. Brain health is essential for longevity, and smoking is a risk factor that can be controlled.

The Rock Round Palace, a unique feature of Ksar Drâa in Algeria, is not only an architectural marvel but also a symbol of the diverse communities that once lived in this desert oasis. Built from locally sourced materials like adobe and stone, the palace reflects the traditional vernacular architecture of the region, blending harmoniously with the harsh Saharan landscape.
For much of the 19th and early 20th centuries, the ksar, including the Rock Round Palace, was home to a significant Jewish community.
Jews, alongside Berber and Arab families, lived in this fortified village, contributing to local trade and crafts. The Jewish presence in the ksar was an important part of the region’s cultural and social life.
However, after Algeria’s independence from France in 1962, the situation for Jews in the country changed dramatically. The new government, led by the FLN (National Liberation Front), sought to build a unified national identity, often at the expense of minority groups, including Jews.
The Jewish community, seen as linked to the French colonial period, became targets of violence and hostility. Attacks on Jewish homes and businesses, threats, and the desecration of synagogues and cemeteries forced many to flee to other countries.
This violent shift in the social and political landscape pushed many Jews to emigrate.
A significant number of Algerian Jews moved to France, where there was already a large Algerian Jewish community, while others moved to Israel, joining the broader migration of North African Jews who faced persecution in their homes.
The persecution, combined with the fear of further violence, led to the gradual abandonment of Ksar Drâa and other similar ksars.
Today, the Rock Round Palace stands as a historical site, a reminder of the diverse cultural heritage that once thrived in the region. Videos circulating on Youtube suggest that anyone off the street can wander inside and around the citadel suggesting it’s not being protected well for future generations.
The remnants of Jewish life, visible in old houses and synagogues, add to the richness of its story and highlight the multicultural history of Ksar Drâa. Let’s hope that one day people of all religions will find safety in any place they call home.
The future is knocking, and it demands solutions. Net-zero isn’t just a buzzword—it’s a survival strategy. But the road to a carbon-free world is filled with potholes. Traditional carbon capture technologies? Too expensive. Too bulky. Too difficult to scale. And the worst part? Many rely on chemical solvents that degrade over time, creating hazardous waste. Enter RepAir Carbon, an Israeli startup rewriting the rules of carbon capture with an elegant, scalable, and affordable solution.
Founded in 2020, RepAir Carbon is the brainchild of some serious innovators. Chairman Yehuda Borenstein, a serial entrepreneur, has a track record of building disruptive tech startups, including LIGC, MataGene, Carbonade, and NitroFix. CEO Amir Shiner steers the ship with a keen focus on commercialization. CTO Dr. Ben Achrai leads the R&D, while Professor Yushan Yan brings the academic firepower—his patented innovations from the University of Delaware form the backbone of RepAir’s tech. Their mission? To make carbon capture efficient, affordable, and sustainable at the gigaton scale.
Forget the old-school, energy-hungry carbon capture plants. It’s the same idea as the machines that suck water from air. They require an enormous amount of energy for what they do making the endeavor almost pointless. RepAir’s electrochemical carbon capture system is a game-changer. Unlike conventional methods, it ditches solvents altogether, slashing operating and capital costs while eliminating waste. The process is fully electric—no heat required—meaning it can run on renewable energy with minimal environmental impact.
The numbers are staggering: RepAir’s solution uses 70% less energy than traditional carbon capture (0.6MWh/tCO2). It operates with a carbon footprint of less than 5%, making it one of the cleanest capture methods available. And, crucially, it’s scalable—a modular design allows for mass production and seamless integration into existing industrial sites.
Power Moves: Shell, Mitsubishi, and More
RepAir isn’t just talking the talk—it’s signing major deals. The company recently inked an agreement with Shell US Gas and Power and Mitsubishi Corporation to develop a large-scale carbon removal project in Louisiana. Meanwhile, in Europe, RepAir Carbon US Inc. has joined forces with C-Questra to launch the EU’s first onshore carbon removal project in Grandpuits, France. This initiative is about more than carbon capture—it’s about local job creation and sustainable infrastructure development.
But that’s not all. RepAir is tackling diluted point source emissions (1%-5% CO2 concentration)—a segment that could bring in multi-million-dollar contracts. Most carbon capture tech struggles with low-concentration CO2 streams, but RepAir’s system is tailor-made for this challenge, opening up a massive new market.
Funding and Expansion
Tech like this doesn’t come cheap, but investors are paying attention. In December 2022, RepAir closed a $10 million Series A funding round, led by Extantia Capital and joined by Equinor Ventures, Shell Ventures, and Zero Carbon Capital. Before that, a $1.5 million seed round in 2021 got the ball rolling. The capital is fueling expansion, R&D, and global partnerships.
With headquarters in Yokneam Illit, Israel, and operations extending to the U.S. (Florida) and Europe, RepAir is positioning itself as a global leader in carbon capture. The vision? A world where CO2 is pulled from the air efficiently, affordably, and at a scale that makes a real impact.
The carbon capture space is heating up. Companies like Carbon Clean, Captura, Charm Industrial, and Agreena are all vying for dominance, each bringing unique solutions to the table. But while others focus on costly infrastructure or niche applications, RepAir’s lean, scalable, and cost-effective model puts it in a league of its own.
Achieving a net-zero future is impossible without carbon capture. But until now, the solutions have been too expensive, too complicated, or too slow to scale. RepAir Carbon is proving that there’s a better way—one that’s ready for the real world. The question isn’t if this technology will transform the industry. It’s when.

The Clore Garden of Science at the Weizmann Institute in Rehovot, is the largest outdoor science park in the world. While it was once a naive and simple, an interactive series of science exhibits for kids has been upgraded since June 2024. The park, inside the world famous Weizmann Institute of Science, and where Einstein once roamed, has undergone significant renovations, introducing several new exhibits that focus on sustainability: such as bamboo treehouses and how to grow food using hydroponics.
The bamboo treehouse is beautiful and shows us how adaptable this sustainable material is for building.
It’s a good day outing with kids under 12 and expect to spend a few hours there as the kids can safely explore the interactive exhibits that encourage play and climbing. An affordable cafe offering lunch means you don’t need to pack a lunch but if you do, there are plenty of tables throughout the park for sitting and eating. Do order tickets in advance.
What you can find at the exhibit, updated in June 2024.
Andoor Science Center: A modern two-story facility now houses various interactive labs, including the AI Media Lab, Culinary Lab, and Multidisciplinary Lab, offering hands-on learning experiences in artificial intelligence, food science, and more.
Garoon Family Legacy Square: This outdoor courtyard showcases some of the garden’s most timeless exhibits, reflecting its evolution into a contemporary science museum.
Amphitheater: Designed as a giant periodic table, this 250-seat amphitheater serves as a venue for educational presentations and events, highlighting the elements that compose our world. Beside the amphi is the old geodesic dome which was once a hydroponic farm. It is now a planetarian-like movie theatre. Large cushions on the floor encourage everyone to come in and spend an hour gazing at the projected stars and movies on the roof of the geodesic dome. You don’t need to tickets to enter.
Movement Exhibit: Engage with interactive installations that demonstrate the mechanics of movement using gravity and water, providing a hands-on understanding of physical principles. The kids were busy trying to pump balls up into the air as though they were in a giant pinball machine.
Light Exhibit: Explore the nature of light through activities focused on vision, perception, and illusions, offering insights into optical phenomena. It wasn’t exactly a TeamLab Borderless experience like in Tokyo, but nonetheless a sweet travel through a tunnel of mirrors.
Not exactly TeamLab Borderless in Japan, but a sweet exhibit for smaller kids
Earth Exhibit: This area features a sustainable village with bridges, composting systems, and a living treehouse, educating visitors about sustainability and climate change.
Who was Chaim Weizmann?
Chaim Weizmann was the father of modern fermentation. He discovered a fermentation process for harnessing bacteria to produce large quantities of useful chemicals such as biofuel.
Albert Einstein With Chaim Weizmann photo 1921
Weizmann was called the father of industrial fermentation. The bacterium Clostridium acetobutylicum was named the Weizmann organism, giving him a taste of fame long before his Israeli political career. His process of Acetone Butanol Ethanol (ABE) fermentation helped produce explosives for World War I and a team of chemical engineers at UC Berkley worked on perfecting his process for the efficient production of biofuels.
Weizmann’s ABE process was initially used to produce acetone which was used in the World War I explosive cordite. Like Alfred Nobel and Albert Einstein, he might have wondered about the moral implications of inventing something which would be used as a tool of war.
The fashion industry is one of the world’s biggest polluters, with synthetic dyes playing a major role in environmental destruction. Every year, textile dyeing releases over 200,000 tons of toxic chemicals into waterways, polluting drinking water, harming aquatic life, and devastating ecosystems. Conventional dyeing processes require vast amounts of water, contributing to severe water shortages in many regions. Meanwhile, synthetic dyes are often made from petrochemicals, leading to increased carbon emissions and long-term soil degradation.
The impact of synthetic dyes on individuals is equally alarming. Many dyes contain carcinogenic and hormone-disrupting chemicals, which can lead to skin irritations, respiratory issues, and allergic reactions for both workers and consumers. Prolonged exposure has been linked to neurological damage and reproductive health problems, making it clear that the dyeing industry’s toxic practices are harming not just the planet but also human well-being.
As consumers and brands alike search for sustainable alternatives, one company is leading the charge in transforming the dyeing industry—Algaeing. This innovative company harnesses the power of algae to create eco-friendly, biodegradable dyes, offering a groundbreaking solution to the toxic world of textile coloration.

Synthetic dyes have been the standard in the fashion industry for decades, but they come with a heavy environmental and human cost. The production and use of these dyes contribute to:
Water Pollution: The textile industry is responsible for 20% of global wastewater pollution. Many dyes contain heavy metals, carcinogens, and toxic chemicals that seep into rivers and oceans, affecting both marine life and human health.
High Water Consumption: Dyeing fabrics can consume up to 200 liters of water per kilogram of fabric, a staggering amount that worsens global water scarcity.
Carbon Emissions: The production of synthetic dyes relies on fossil fuels, releasing greenhouse gases that drive climate change.
Harm to Workers: Textile dye workers are frequently exposed to harmful chemicals, leading to respiratory diseases, skin disorders, and even cancer.
Microplastic Pollution: Many synthetic dyes are used in polyester and synthetic textiles, contributing to microplastic pollution in the environment.
With fashion brands and policymakers increasingly prioritizing sustainability, the industry is in desperate need of an eco-friendly alternative. Enter Algaeing—a company proving that nature itself holds the key to cleaner fashion.
What is Algaeing?

I keep a wary eye open against illness, and prefer to immediately treat any scratchy throat, cough, or stomach upset with natural remedies. It usually works. But it’s happened that illness has caught me first.
I wonder what would have become of me without antibiotic treatment for pneumonia with peritonitis at one time and a post-partum breast infection at another. Later in life, I had a whopper all-around infection of the chest, throat, eyes, and ears after a loved one died. My immunities had bottomed out due to exhaustion and grief. Antibiotic meds got me back on my feet, and I’m here to tell the tale.
Strep throat, bronchitis, urinary tract infections and other ailments appear any time. We can almost shrug and say, “People get sick.” We’re confident that we’re going to be uncomfortable for a while, but that we’ll survive: there’s antibiotics.
Yet there’s another side to antibiotics. At the same time that antibiotics kill harmful bacteria, they destroy beneficial bacteria that live in the gut and keep us healthy. According to a study of intestinal bacteria published in the journal Clinical Infectious Diseases, “Gut microbiota (micro-organisms) mostly repopulate within two to four weeks of finishing a course of antibiotics. However, it can take up to a year or longer for your gut microbiome to fully recover.”
Microbiomes are colonies of specific bacteria that live in specific places in or on the body. Here we’re focusing on the health-supporting bacteria that are found in the large intestine or colon, but also in the vagina. These “good” bacteria are often weakened or largely destroyed by antibiotic treatment.
So what can be the effects of weak, or absent good bacteria?
Commonly, nausea, gas, diarrhea and a scraped sensation in the gut. In women, a yeast infection may occur after a round of antibiotics. People complain of feeling “wiped out” after illness treated with antibiotics; not only because illness is debilitating itself, but because the bacteria that nourish their colon and prevent inflammation aren’t there.
It may also happen that a person whose gut bacteria have vanished either extensive treatment with antibiotic meds, gets sick again – needing another round of antibiotics. A continuing cycle of illness/antibiotics can lead to a severe gut infection called Clostridium difficile. It’s a life-threatening condition. in 2023, the FDA approved a new therapy for that: poop pills. Transferring fecal bacteria from a healthy donor replaces up to 95% of the missing bacteria in the patient’s depleted gut.
But don’t get grossed out. The good news is, that in common cases, it’s more than possible to encourage gut health, and to replace missing healthy bacteria. It’s even easy. It’s about eating pre-biotic foods regularly, to help maintain a high level of healthful bacteria.
Let’s look at the difference between prebiotic and probiotic foods.
Prebiotics are rich in fiber and pass through the body partially undigested. Think of whole grains, sourdough bread, organic leafy greens and fruit. According to the American Society for Nutrition, dandelion greens, Jerusalem artichoke, garlic, leeks, and onions have the highest amounts of prebiotics. Their list includes onion rings, creamed onions, cowpeas, asparagus, and Kellogg’s All-Bran cereal.
Probiotic foods are a slicker trick, many either being liquid, semi-liquid, or having been fermented in liquid, usually brine but sometimes milk. Here we’re looking at miso soup,; vinegar-free sauerkraut (and here’s how to make your own); kimchi; kombucha; yogurt with active culture; kfir, and unpasteurized pickled vegetables.
You can make many gut-friendly foods at home, such as labneh, a tangy spread based on yogurt. Start with yogurt whose label reads “bio-active” or “active cultures” or some such label indicating it has active friendly bacteria.
You do have to locate kfir grains and the kombucha starter (also called the mother) first. I’ve acquired both by putting out a call on my local WhatsApp groups, but if that doesn’t work for you, natural foods stores often carry them. Otherwise, there are many online sources.
A weird mother
What to avoid eating while taking antibiotics:
Some authorities warn that dairy and calcium-rich foods bind the meds to the calcium and prevent them from being absorbed by the body. The list includes tofu, kale, fortified cereals and orange juice, alternative milks and chia seeds; all calcium-rich. But you can eat them if you wait two hours after taking the antibiotic and six hours before the next dose.
High acid foods like citrus, sodas, chocolate and tomato products may interfere with absorption of certain meds. Best to stay away from them altogether while on antibiotics. Caffeine and alcohol are on the list too.
Surprisingly, multi-vitamins and antacids are also on the “take it easy” list while taking antibiotics. These products contain minerals that bind to the meds and prevent their absorption. As with calcium-heavy foods, take the vitamins and antacids two hours after you take your antibiotic and six hours before your next dose.
Read the label or the pamphlet inside the box. If it says to take with food, you can take your medicine with a meal or a little snack like crackers and fruit. Food helps the body to absorb certain medications and can reduce side effects. If the product should be taken on an empty stomach, time your meals to be either one hour after you take the medicine or two hours before your next dose.
And no matter what, stay hydrated while you’re sick. Drink plenty of water or warm herbal tea like mint or chamomile.
After finishing the course of antibiotics, it’s wise to continue eating probiotic foods. Indulge, and enjoy.
We love Dr. Bronner’s sustainable and regenerative chocolate. Chocolate lovers are always on the lookout for new and exciting flavors, and camel milk chocolate is quickly gaining attention as a delicious and sustainable alternative to traditional dairy-based chocolates. But what makes camel milk chocolate special? Where can you buy it? And why is camel milk considered a more sustainable choice? Let’s explore.
Dr. Bronner chocolate
What Does Camel Milk Chocolate Taste Like?
Camel milk chocolate has a distinct flavor that sets it apart from regular cow’s milk chocolate. It is often described as being creamier, with a slightly salty and caramel-like undertone. The natural sweetness of camel milk allows for reduced sugar content in chocolate, making it a healthier option for those looking to cut back on added sugars.
Additionally, it lacks the strong aftertaste that goat’s milk chocolate can have, making it an appealing choice for those seeking something new yet familiar.
Why Is Camel Milk More Sustainable?
Lower Environmental Impact – Camels require significantly less water than cows, making them a more sustainable option in arid and drought-prone regions. They can thrive in desert environments where other dairy-producing animals would struggle, reducing the need for artificial irrigation.
Why hasn’t drinking camel milk caught on?
No Need for Intensive Farming – Unlike large-scale dairy farms that often contribute to deforestation and greenhouse gas emissions, camels can be raised in natural desert ecosystems without destroying native flora and fauna.
Nutritional Benefits – Camel milk is rich in vitamins and minerals, including iron, vitamin C, and B vitamins, while being lower in fat and lactose than cow’s milk. This makes it a suitable alternative for those with lactose intolerance or those looking for a more nutrient-dense dairy source.
Where to Buy Camel Milk Chocolate
If you’re curious to try camel milk chocolate, several brands and retailers offer this unique treat:
Al Nassma (UAE) – One of the pioneers in camel milk chocolate, offering a variety of flavors including whole milk, dark chocolate, and nut-infused varieties. Available online and in select luxury stores worldwide.
Dubai-based chocolate shops – Many specialty confectioners in the UAE sell camel milk chocolate, making it a must-try if you visit the region.
Amazon and Online Specialty Stores – Some online marketplaces offer camel milk chocolate for international delivery.
Local Health Stores and Gourmet Shops – Some high-end or organic stores may stock camel milk chocolate, particularly in regions that promote sustainable and ethical food choices.
Can camel milk work in a keto diet?
Camel milk can be considered keto-friendly in moderation. One cup of full-cream camel milk contains approximately:
100 calories
5g protein
8g carbohydrates
5g total fat
3g saturated fat
Since the ketogenic diet typically limits daily carbohydrate intake to 20-50g per day, camel milk’s 8g of carbs per cup may fit within that range if consumed in moderation. However, compared to other keto-friendly dairy alternatives like almond milk (which has fewer carbs), camel milk is on the higher end in terms of carbohydrate content. If you’re strictly following a keto diet, it’s best to use camel milk sparingly or opt for a lower-carb alternative.
I hate to buy new things and prefer vintage finds. But when it comes to a travel backpack, it’s wise to have something new and dependable. As an owner of the Cotopaxi Allpa 42L Travel Pack in light blue, priced at $250, I can confidently say it’s one of the best travel bags I’ve ever had. The design is both functional and stylish, with a suitcase-style opening that makes packing and organizing effortless. The internal compartments and mesh pockets keep everything in place, and I love the addition of a stretchable water bottle pocket and a luggage pass-through strap—it just makes traveling so much smoother.
One of the things I love most about this backpack is the color. The vibrant mix of blues and subtle color accents gives it a unique, personal feel—like it was made just for me. It’s not just another generic bag; it has character, and that makes me want to keep it for a long time. And that, in itself, is a form of sustainability—buying something you truly love and want to keep instead of replacing it frequently.
Beyond aesthetics, the sustainability aspect is a huge plus. Cotopaxi was founded by Davis Smith, an entrepreneur passionate about using business as a force for good. Inspired by his childhood in Latin America, where he saw both the beauty of nature and the struggles of poverty, he created Cotopaxi with a mission to give back. As a Certified B Corporation, Cotopaxi meets high social and environmental standards, ensuring that their products make a positive impact.
The Allpa 42L is made from 100% recycled polyester and repurposed nylon, reducing waste and keeping materials out of landfills. The company also focuses on fair labor practices by partnering with factories that ensure safe working conditions and fair wages for workers. Their Del Día collection uses leftover fabric from other companies’ production runs, preventing textile waste and creating one-of-a-kind designs. Cotopaxi also prioritizes carbon neutrality, offsetting emissions through environmental projects.
Additionally, their Gear for Good initiative donates a portion of revenue to poverty alleviation, education, and environmental conservation efforts, particularly in underserved communities. Knowing that my purchase supports not just sustainability but also global humanitarian efforts makes me feel even better about this backpack.
Overall, the Cotopaxi Allpa 42L isn’t just a backpack—it’s a long-term travel companion. Between its durability, smart design, ethical production, and the personal connection I feel with its colors and craftsmanship, I know this is a bag I’ll cherish for years.

Discover how sustainable investing and Green Forex can transform finance. Learn how ESG factors influence currency stability for a greener future.
Sustainable investing, which was once a niche concept, has now become a mainstream financial strategy. Today’s investors understand and value environmental, social, and governance (ESG) factors more than ever, making them key considerations in allocating their assets. This change comes from two main factors: clients increasingly want their investments to align with their values, and there’s growing recognition that sustainable practices can lead to better long-term financial results.
What Are Sustainable Investing and Green Forex Strategies?
Sustainable investing means investing in companies that follow ethical and responsible practices, which helps them operate more environmentally and socially consciously. The fundamental purpose behind sustainable investing revolves around using financial resources to drive positive societal changes and benefits. Investors have various options, including buying shares in companies producing solar panels or biofuels or joining community loan funds.
The three main subheadings under sustainable investing represent various investment areas in this field.
Environmental investments evaluate companies’ management of non-renewable resources and their approach to climate issues and clean energy transitions.
The social component of sustainable investing examines initiatives that address human rights issues and diversity concerns. These topics cover both gender equality and support for underprivileged communities.
The governance element of sustainable investing evaluates companies that promote business ethics alongside trust, transparency, and marketplace compliance. These businesses prioritize ethical practices above all else while treating profits as a secondary goal within their organizational structure.
Sustainable investment has also influenced the forex market by creating “Green Forex.” This foreign exchange form is growing on MT4 trading platforms. Why? Investors now assess ESG factors when evaluating currency strength because countries with eco-friendly policies often experience improved currency stability.
According to an IISD publication by David Uzsoki, in 2036, nearly all global assets under management could incorporate ESG principles. Sustainable investing and Green Forex could play a pivotal role in the future of finance. Let’s find out more.

The Rise of Sustainable Investing, Market Expansion, and Growth Trends
According to MSCI, ESG Investing began back in the 1960s. However, during that era, people invested in them as a political statement, with investors avoiding stocks linked with tobacco. Today, this concept has grown beyond political activism. It is now a values-based part of financial analysis. Investors see it as a complementary strategy with fewer “activist” connotations.
Sustainable investing has come a long way in its over six decades of existence. Grand View Research reports that the global ESG investing market was valued at USD 25.10 trillion in 2023. Europe dominates with 85% of sustainable funds, totaling USD 2.5 trillion in 2023. In the same report, the market is projected to grow at a compound annual growth rate (CAGR) of 18.8% from 2024 to 2030. The growth will stem from rising awareness and demand for value-aligned, sustainable investments.
ESG assets will keep rising as investors see their long-term potential. In 2023, sustainable funds returned 12.6%, outperforming traditional funds’ 8.6%. This outperformance spans equity and fixed-income assets. Therefore, sustainable investing is not just an ethical choice but a financially sound one.
Green Forex Strategies – A New Frontier
The forex market is the world’s largest financial market. Currency trade is based on economic, political, and social factors. Traders have traditionally focused on interest rates, inflation, and geopolitical tensions, which aid in predicting currency movements. However, this doesn’t seem so anymore, with the ESG wave reshaping forex trading.
Countries with strong ESG policies attract more foreign investment, boosting their currency value. Conversely, nations with poor sustainability may see weaker currencies. That said, here are case studies on how ESG impacts currency values;
The Euro and Green Energy policies: The EU implements green policies like the European Green Deal. This aims for carbon neutrality by 2050. These initiatives make the euro attractive to environmentally conscious investors. This way, the euro has stability.
Norway’s Sovereign Wealth Fund: Norway integrates ESG principles into its sovereign wealth fund management. They prioritize investments in sustainable industries. This strategy supports the Norwegian krone’s stability despite changes in oil prices.
Future Predictions and Emerging Trends
As the world advances towards a more sustainable future, ESG factors will play an essential role in financial investments such as forex markets.
Investors who incorporate ESG financial assets into their portfolios will likely have a competitive edge. Central banks may also set monetary policies based on ESG factors.
As green policies and ethical governance become the norm, here are key trends to anticipate:
Increase in ESG-oriented investments
Investments in renewable energy, particularly solar and wind
Redirecting financial resources to protect and manage natural ecosystems sustainably
Carbon trading and CO₂ footprint offsetting
Technological Advancements — Blockchain and AI enhancing ESG reporting transparency and efficiency
Moshe Safdie’s Habitat 67 is considered a sustainable design but is it regenerative?
“Regenerative design, as a philosophy and practice, aims not merely to limit the damage we cause to the environment but to restore natural systems.”
Academics from the University of Bath have issued a new resource on the potential for regenerative design to deliver net-positive benefits, as well as actionable principles for change. RENEW: a manifesto for regenerative design and engineering is a 35-page electronic guidebook developed by the university’s Centre for Regenerative Design & Engineering for a Net Positive World (known as RENEW).
The RENEW center takes a cross-disciplinary approach to developing systems for the built environment that harmonize benefits to society with the natural world.
RENEW combines expertise from more than 40 academics, researchers, and industry stakeholders in water and chemical engineering, materials and composites, and placemaking and architecture with social science, economic, governance, and ecological studies.
The University of Bath’s Centre for Regenerative Design & Engineering for a Net Positive World (RENEW) has released a guidebook focused on defining regenerative design and expanding awareness of its prospects.

Regenerative > Sustainable?

Technology, science, and education have long focused on improving the human experience—such as by extending life expectancy worldwide—and evolving the spaces where we live, work, and play, but have done so through “extractive, non-regenerative practices,” said RENEW members in the manifesto.
Sustainability has been championed for four decades to manage and minimize damage to the Earth’s resources but has been slow to penetrate the industrialized world. The guidebook’s authors note that contemporary net-zero emissions efforts and global climate target policies do not prescribe a way forward for “human systems to contribute positively to natural systems.”
In order to adequately mitigate the impacts of climate change, improve biodiversity, and rebalance social inequities, the RENEW manifesto authors indicate that society requires an evolution from resource exploitation to a framework that prioritizes restoration of the global ecosystem.
In an announcement launching the RENEW guidebook, center director and professor Sukumar Natarajan said that the initiative is designed to provide guiding principles for engineering, architecture, and other disciplines that enable society to “create resilient, fair communities that can thrive in balance with nature, while improving standards of living.”
The RENEW manifesto lays out six guiding principles of regenerative design, then offers a framework for putting them into practice. The six principles include:
Reflective governance—Establish continuously evolving metrics and monitoring practices to track progress and impact.
Embrace interconnectivity—Recognize that the world is intricate and interdependent. Take a holistic view accounting for the dynamic relationships between ecosystems and communities.
Work as nature—Work harmoniously with and as nature. Design systems that work as part of species and ecosystem patterns, processes, and cycles.
Prioritize net positive—Prioritize regeneration, replenishment, and restoration, recovering and reusing waste to create net-positive solutions and an abundance of resources. The aim should be to repair, sustain, and enrich the planet, rather than deplete its precious resources.
Cultivate resilience—Systems should be designed with a capacity to adapt, diversify, and self-renew even in the face of uncertainty, change, and disturbances.
Transmit—Document, curate, and publicize to help proliferate best practice through active discourse on a global scale.
The authors concluded that the guide is intended as a foundation for continuously evolving this multidisciplinary approach to solving building/engineering problems.
Center co-director Emma Emanuelsson observed that “We want this manifesto to help create a less anxious future for today’s young people, and for humans and nature to prosper in equal measure. It may not show us the full journey, but it does have advice and a framework to allow us to get started.”
Terviva is an agricultural innovation company partnering with farmers to grow and harvest pongamia, a climate-resilient tree which helps to reforest land and revitalize communities.
At a recent panel discussion, the moderator posed a familiar question: “Why is your company confident that your sustainable product will be successful?” One panelist eagerly responded, “Because it’s what consumers want!”
While optimistic, this response reflects a common misconception: consumer interest in sustainability automatically translates to commercial success. This misconception becomes especially evident when you look beyond consumer markets where purchasing managers need to balance the environmental objectives with other more fundamental things, like budgets and the capabilities of the product.
While it’s undeniable that consumers are increasingly prioritizing sustainability—data reveals that they are willing to pay a 9.7% premium for sustainable products—this demand is only one piece of a much larger puzzle. Successful sustainable products must engage multiple stakeholders across the entire value chain, and the success of sustainable products in 2025 will hinge on their ability to address broader business imperatives beyond mere consumer trends.
Think of it this way: sustainability is not just a passing fad or the latest hot-button issue; it’s a comprehensive business strategy.

The Path to Success: A Holistic Approach
So, what do we mean when we say “broader business imperatives?” Fundamentally, we’re talking about how the business operates, its overall operational efficiency, and how a product addresses key sustainability objectives (like land and water consumption or the carbon impact of production).
At Terviva we’ve learned that some of the reasons investors and partners want to engage with us to plant trees are not just because it’s a compelling story.
They are compelled by the risk mitigation benefits of our genetics and orchard design trials for example, and having patents around our IP for the end products provides proof points that mitigate go to market risk. Here are three critical aspects that industry leaders can learn from our experience in bringing sophisticated partners onboard in their quest for sustainable success:
Product Innovation: Sustainable products must solve real challenges for stakeholders. This means developing solutions that meet consumer demand, enhance operational efficiency, and reduce environmental impact. Companies should prioritize innovative approaches that regenerate ecosystems, optimize resource use, and create value across the supply chain.
Operational Excellence: Efficiency is key to sustainable success. Organizations must strive to maximize yield while minimizing waste. This involves adopting advanced technologies and practices that enable greater productivity with fewer resources. Companies that focus on operational excellence will meet market demand and contribute positively to environmental goals.
Market Integration: Sustainable products must address fundamental business challenges, including carbon emissions, land use, and supply chain dynamics. By aligning sustainability initiatives with core business objectives, companies can create compelling value propositions that resonate with stakeholders at all levels.
This integrated approach fosters collaboration and drives meaningful progress toward sustainability goals. For instance, automakers that invest in electric vehicle technology respond to consumer demand and tackle regulatory pressures and long-term viability in an increasingly eco-conscious market. Equally, companies that build sustainable, short supply chains tend to be more resilient to the kinds of disruption we saw during and immediately after the COVID-19 pandemic.
The bigger picture
The key takeaway for industry leaders is clear: sustainable products will flourish in 2025, not just because they are trendy, but because they tackle critical business challenges while delivering conservation benefits. Companies prioritizing holistic solutions—addressing the needs of consumers, businesses, and communities—will be best positioned to lead the charge toward a sustainable future.
In an era where sustainability is a long-term business strategy, embracing this multifaceted approach is essential for long-term success and industry leadership. As we progress, the challenge will be to sustain the strong momentum towards sustainability. By advocating for sustainable business practices and incorporating them into our own operations, we show that you don’t need to choose between the planet and the bottom line.
Getting at least 30 minutes of daily summer sun in the first year of life may mean a lower relapse risk for children who are diagnosed with multiple sclerosis (MS) later, according to a study published on February 12, 2025, online in Neurology, Neuroimmunology & Neuroinflammation, an official journal of the American Academy of Neurology.
The study also found if a child’s biological mother had at least 30 minutes of daily sun during the second trimester of pregnancy, the child had a lower risk of MS relapses. The study does not prove that sun lowers relapse risk for children with MS, it only shows an association.
Multiple sclerosis is a disease which prevents the nerves from sending signals to the body to move, sense or function. MS is not present at birth. It develops as the immune system matures. Less than 1% of people who have MS are diagnosed before age 10. But there is an association and genetic risk.
“It is important not to spend too much time in the sun without sun protection, however greater exposure to sun has been tied in previous research to a lower risk of developing MS in childhood,” said Gina Chang, MD, MPH, of The Children’s Hospital of Philadelphia and member of the American Academy of Neurology. “It’s encouraging that our study found that greater sun exposure during early development may also be beneficial in helping to reduce disease activity in children who are later diagnosed with MS.”
For the study, researchers looked at health records from 18 MS clinics across the United States to identify 334 children and young people with childhood-onset MS age four to 21. Participants were within four years of experiencing their first symptoms. The median follow-up time was 3.3 years.
To determine sun exposure, participants’ parents or guardians completed questionnaires that asked how much time the participant and their biological mother had spent in the sun at various periods of life, what kind of clothing they typically wore and how often they used sunscreen.
Of the total group, 206, or 62%, experienced at least one relapse during the study. Relapses were defined as new or returning symptoms lasting for at least 24 hours and separated by at least 30 days from the last MS attack, without a fever or infection.
They found that of 75 participants who had 30 minutes to an hour of daily summer sun during their first year of life, 34 children, or 45%, had a relapse. Of the 182 participants who had less than 30 minutes of daily summer sun during their first year of life, 118 children, or 65%, had a relapse.
After adjusting for factors such as tobacco exposure in the first year of life, season of birth, the type of MS medication taken and use of sun protection such as sunscreen, hats and clothing, researchers found that 30 or more minutes of daily summer sun during the first year of life was associated with a 33% lower risk of relapse compared to less than 30 minutes of daily summer sun.
Researchers also looked at sun exposure for the biological mothers of the children.
They found that 30 minutes or more of daily sun during the second trimester of pregnancy was associated with a 32% reduced risk of relapse for their child with MS.
“Our findings suggest that sun exposure in early childhood may have long-lasting benefits on the progression of childhood-onset MS,” said Chang. “Future studies should look at how time in the sun at other time periods before and after MS diagnosis affects disease course, to better guide sun exposure recommendations for children with MS and to help design potential clinical trials.”
A limitation of the study was that it relied on participants’ parents or guardians reporting their sun exposure and use of sun protection, which they may not have remembered accurately.
During the Spring Meeting in Chiang Rai, Thailand, AIPH The International Association of Horticultural Producers members consist of thousands of growers of flowers and ornamental plants around the world opened entries for the third edition of the AIPH World Green City Awards – the only global awards for cities where plants and nature are the core focus.
The Awards recognise and celebrate bold and innovative action that harnesses the power of plants and nature to create greener, healthier, and more resilient cities.
“Today, more than ever, we are faced with an epic challenge: ensuring that our cities remain liveable and resilient in the face of climate change and growing urbanisation,” says AIPH President Leonardo Capitanio. “As climate change predictions become reality, it is clear that plants will be among the most valuable resources we have to keep our cities comfortable. We must recognise the importance of plants and trees and their ability to adapt to stress in order to ensure the health and well-being of us all.”

Researchers at Rice University in Houston, Texas, have developed a new method for performing chemical reactions using water instead of toxic solvents.They call it green chemistry. We wrote about the potential of water over toxic solvents way back in 2008. The idea is now coming to fruition. Baby steps in science.
The scientists created microscopic reactors capable of driving light-powered chemical processes by designing metal complex surfactants (MeCSs) that self-assemble into nanoscale spheres called micelles. This innovation could drastically reduce pollution in industries including pharmaceuticals and materials science, where harmful organic solvents are often necessary.
The new micellar technology represents a step forward in sustainable chemistry. These self-assembled micelles form in water, where their hydrophobic cores provide a unique environment for reactions, even with materials that are typically insoluble in water.
The research team led by Angel Martí, professor and chair of chemistry at Rice, demonstrated that this system can efficiently perform photocatalytic reactions while eliminating the need for hazardous substances. The study was published in Chemical Science Feb. 10.
“Our findings show how powerful molecular design can be in tackling chemical sustainability challenges while maintaining high chemical performance,” Martí said. “We’ve created a tool that could transform how chemical reactions are performed, reducing environmental harm while increasing efficiency.”
How the discovery works
Surfactants are molecules with a dual nature: One part is attracted to water, while the other repels it. When added to water, they naturally form micelles or tiny spheres where the water-avoiding parts gather in the center, creating a small reaction space. The scientists modified these surfactants by adding a light-sensitive metal complex to their structure, making the MeCSs.
The researchers tested different versions of the MeCSs by altering the length of their hydrophobic, or water-repelling, tails. They found that these molecules could form micelles as small as 5-6 nanometers, much smaller than those in similar systems. The team used these micelles to perform a photocatalytic reaction, achieving high yields without needing harmful solvents.

“These micelles act like tiny reaction vessels,” said Ying Chen, first author of this study and a doctoral student in chemistry at Rice. “They enable chemical transformations that wouldn’t normally work in water while being more sustainable than traditional methods.”
Why this matters
Many chemical processes in manufacturing and research rely on organic solvents, which are harmful to the environment and expensive to handle safely. The development of photoactive water-based micelles capable of driving chemical reactions offers a safer, greener alternative. Additionally, the system can be reused, improving its cost-effectiveness and environmental footprint.
In 2008 we reported on the groundbreaking work, thanks to a groundbreaking discovery at Tel Aviv University. Prof. Arkadi Vigalok from the School of Chemistry has discovered a way to use water to make certain steps of a complicated chain of chemical reactions more environmentally-friendly.
Prof. Vigalok’s solution replaces chemical solvents, which can pollute the environment, with water. Though chemists have long thought it possible, Prof. Vigalok’s approach has only rarely been even attempted. His discovery was reported in the journal Angewandte Chemie, International Edition. Once ideas are published in the scientific community they become open-source questions and challenges for the science community around the world to solve.
