In Canada, only 1 in 5 children who need mental health services receive them. Clinical and psychiatric programs, while effective, can involve long wait times and prohibitive costs. A new study involving McGill University researchers points to a solution to fill the gap: a low-cost, community-based program that has seen inspiring results.
Children exposed to violence are known to face higher risks of violence in the future, either as perpetrators, survivors, or witnesses. LOVE Quebec works with youth who have experienced violence to help break the cycle. In a previous study of its after-school program, participants reported an 80 percent decrease in violence in their lives and increased retention in school, while also promoting their overall mental health more broadly.
To unlock the key to its success, researchers from McGill, Université du Québec à Montréal, and Université de Sherbrooke studied LOVE’s Media Arts Program (MAP) in two Quebec urban high schools between 2018 and 2019. The program involves photography, writing, and poetry, among other activities.
Playfulness: The perfect prescription?
In the face of the participants’ profound and challenging life circumstances, the results indicate that adopting a playful approach is instrumental in fostering their willingness to share their experiences.
“There’s an important element of playfulness, which is modelled by LOVE staff,” says Franco Carnevale, a professor at McGill’s Ingram School of Nursing and the study’s principal investigator. “The outcome is an extraordinary non-clinical approach to mental health promotion and wellness that helps young people without making them feel like patients.”
The researchers propose that play sparks a positive cycle by reducing stress levels, allowing youth to change their relationship with vulnerability—by expressing it in a safe space.
The findings build upon team’s previous study about LOVE’s MAP after-school program. The mounting body of evidence demands a closer look at how low-cost community programs can help elicit the voices of children, whose experiences may be difficult to understand.
“I think we should see youth well-being as a public health priority with more active government support and more widescale mobilization,” explains Carnevale. “LOVE provides a highly impactful model, and it might just be the perfect prescription for some of the mental health challenges faced by youth today.”
Solar energy is all the rage these days, and for good reason. With climate change looming, solar panels offer homeowners a way to personally combat rising CO2 levels while saving some green at the same time. However solar panels don’t just fall from the sky into your yard fully formed. You need to decide what kind of panels to get, review the best solar companies, and calculate the efficiency of solar panels to cover your energy needs. This choice implies lots of research and number crunching to find out the return on investment based on solar.
Advantages of Financing Solar Power Plants
On the one hand, our way to going solar is beneficial not only in terms of nature; it also can please customers with its cost-efficient approach. The act of putting up residential metallic solar panels on roofs allows the users to use sunlight hence making electricity into power for household usage. Although solar panels are not free, and they do require an initial investment, homeowners discover that substantial savings on their energy bills as well as tax credits often make the move to going with sunny power quite appetizing. But before you get started with your solar energy adventure, locating potential reliable solar companies is a necessity what I also would advise is not to choose any company arbitrarily but only one of good repute. Search for those companies that have a track record, positive customer reviews, and relevant certificates. This will, therefore ensure a smooth installation process.
The cost of solar panels has reduced drastically over the last few years hence ensuring that this becomes affordable and accessible. The federal government in addition to most states and other tax-levy providing entities provides huge incentives as well rebates for solar panels installation, which is another reason why adoptable renewables are deemed convenient by many individuals. In the U.S., a tax credit through ITC – Investment Tax Credit or federal solar investment tax credit allows homeowners to deduct 26% cost of installing Solar Panels from their Federal income taxes owed. Furthermore, most states and local utilities provide even bigger rebates that can cut the whole system in half by up to 75%.
Lastly, solar panels may help increase the home’s value and attract environmentally concerned potential buyers. For most homeowners, the energy cost savings, tax incentives rebates, and increased value of homes make solar an investment that pays itself out for the lifetime of the system. Overall, although first solar panel system investments may seem to be quite high, the long-term economic advantages of producing energy based on these modules are staggering.
When analyzing solar panels costs vs future savings, you understand that going solar is a great investment. Several factors contribute to the overall economics of solar panel installations, including the cost of equipment, installation expenses, maintenance, and the potential savings on electricity bills.
Upfront Costs
The upfront costs of solar panel installations include the purchase of panels, inverters, mounting hardware, and the installation itself. While these costs can be substantial, they are offset by potential incentives, rebates, and financing options, making solar energy more accessible to a broader audience.
Return on Investment (ROI)
The return on investment is a critical metric in evaluating the economic viability of solar panel installations. As solar panels generate electricity and reduce reliance on traditional grid power, the savings on electricity bills contribute to the ROI. In many cases, homeowners and businesses experience a positive ROI within a relatively short period, especially when taking advantage of government incentives.
Long-Term Savings
Solar panels have a long lifespan, often exceeding 25 years. Over this period, the savings on electricity bills accumulate, making solar energy an economically sound investment. Additionally, as technology advances and becomes more cost-effective, the overall economics of solar energy continue to improve.
The good news is, that once your system is installed, solar panels can provide free electricity for 20-30 years or more and increase the value of your home. By calculating all the factors that determine your specific costs and incentives, you can make an informed decision about whether the long-term benefits of solar power outweigh the initial investment for your situation.
Solar Panel Installation Tips
Evaluate Your Energy Need
Conduct an energy audit to understand your current energy consumption. This will help determine the size of the solar panel system needed to meet your specific requirements. By accurately assessing your energy needs, you can optimize the efficiency and cost-effectiveness of the solar installation.
For sizes of the system in KWs and their size directly influence the total price. Typically, most residential systems have a capacity that falls between 3 kW and 8 kW depending on the size of the house. Systems in these larger capacities around 10 to 15 kW would be suited for houses with electric heating and air conditioning. However, the real solar panels are only 15-25% of total charges. Other factors that must be included here include inverters, racks, and the installation also.
Contemplate Government Incentives, Rebates
Several governments provide incentives and rebates to promote the use of solar energy. Study the programs that are available in your area, these can significantly cut down costs on installation. Sometimes, these incentives could comprise tax credits and feed-in tariffs.
Explore Financing Options
Although up-front costs of solar panel installation are quite high, there exists a wide range of financing options that bring about the transition at more affordable prices. Some of these alternatives may consist of solar loans, leasing contracts, or PPAs. Assess each option to discover your preference.
In conclusion, solar panels would be a wise investment for many homeowners who want lower energy bills and to achieve carbon neutrality. Although the initial sticker shock of an installation’s price tag is high by comparison, combined with tax credits, incentive programs, and decades-worth of free sunshine solar system can essentially pay for themselves over time. With an increase in the productivity of panels and a decrease in prices each year, turning sun rays into energy becomes cheaper. Taking into consideration the tips to start using green energy, solar panel installations can be a bright solution to enjoy.
Air pollution makes the scent of a night-blooming plant less enticing to pollinating moths. Researchers in a Science study discovered that nitrate radicals severely degrade key odour components that attract pollinating insects to the pale evening primrose (Oenothera pallida).
Nitrate radicals, which can come from various sources including vehicle emissions, are particularly abundant when there’s no sunlight to break them down.
Artificial flowers spiked with the pollution-degraded scent received 70% fewer visits from wild hawkmoths than fake flowers with intact odour. Because hawkmoths are some of the primrose’s main pollinators this could reduce the plant’s fruit production by almost 30%.
Moths and car exhaust
The study is a bit scary for pollinators like bees and moths, as the perils of air pollution are widely acknowledged, spanning from its contribution to global warming to its detrimental effects on human health. This study tells the impact on the relationship between flowers and pollinating insects.
According to researchers, these nitrate radicals, prevalent in urban nighttime air, can significantly diminish the fragrance emitted by flowers, thereby deterring visits from crucial pollinators like hawk moths.
Sensory pollution could disrupt plant reproduction processes, potentially leading to decreased fruit production. Moreover, it poses a threat to pollinators themselves, exacerbating the already alarming global decline in their populations.
Joel Thornton, an atmospheric chemist at the University of Washington and co-author of the study, emphasizes the significance of these findings, stating, “We worry a lot about exposure of humans to air pollution, but there’s a whole life system out there that’s also exposed to the same pollutants.”
The research team, led by Dr. Thornton, along with his colleague Jeff Riffell, a sensory neurobiologist and ecologist at the University of Washington, and their former doctoral student, Jeremy Chan, who is now a researcher at the University of Naples, conducted extensive experiments focusing on the pale evening primrose, a plant reliant on nocturnal pollinators like hawk moths.
Dr. Riffell explains the sensitivity of hawk moths’ olfactory system, likening it to that of a dog’s. Through their experiments, the researchers identified 22 chemical compounds comprising the primrose scent, with particular attention to monoterpenes, which are crucial for attracting hawk moths.
To simulate the effects of pollution on flower fragrance, the scientists introduced ozone and nitrate radicals to the scent. While ozone exhibited some degradation of scent compounds, nitrate radicals proved significantly more damaging, leading to an 84 percent reduction in key moth attractants.
Further experiments conducted in wind tunnels and natural environments confirmed the detrimental impact of pollution on moth behavior and flower visitation rates. Flowers emitting a pollution-degraded fragrance received significantly fewer moth visits compared to those with an intact scent, potentially leading to a notable decrease in fruit production.
Dr. Riffell underscores the broader implications of their findings, suggesting that the problem extends beyond the specific interaction between hawk moths and primroses. Many pollinators rely on similar scent cues, indicating a potential widespread impact on ecological communities.
Through computational modeling, the researchers also estimate that pollution has drastically reduced scent-detection distances in cities worldwide since the preindustrial era, further emphasizing the pervasive nature of this issue.
In conclusion, the study highlights the intricate interplay between air pollution, floral fragrance, and pollinator behavior. By elucidating the profound effects of pollution on ecological systems, it underscores the urgent need for comprehensive strategies to mitigate air pollution and safeguard biodiversity.
Genes from a bioluminescent fungus allow the glowing petunia to produce enzymes that can convert caffeic acid (an intermediate in the biosynthesis of lignin) into the light-emitting molecule luciferin and then recycle it back into caffeic acid.
Glowing plant hits the US market
Plant lovers in the United States will soon be able to buy glowing petunias (Petunia hybrida).
The $29 US plant, sold by biotech firm Light Bio, contains genes from a bioluminescent mushroom (Neonothopanus nambi).
Because this type of petunia is not native to North America and is not considered an invasive species, the chances of the modified genes spreading should be minimal – says the company.
This is a “groundbreaking event”, says plant biologist Diego Orzáez. He suggests that having “something people can touch and bring home” could even help people to be less scared of genetic engineering.
Man poses with photo of trees he helped restore
Do you think genetic engineering should be taken this lightly and that plants that glow should be sent home to teach kids about how “cool” genetic engineering is? We should be teaching kids about protecting the diversity of plant life, and help them celebrate people who plant forests, and who save apple varieties across the United States.
A tiny home can help cut down your carbon footprint.
Today, environmentally friendly building practices are much more than just a trend—they are an absolute need. It is important when we are aiming to solve environmental problems and overcome the limitations of our ecological footprint, making energy efficient buildings have come to play an essential role. This article describes 10 innovative tools for energy efficiency and there is a pledge that this could lead to the future of a more sustainable environment. Remember, as what Resustain said – the cheapest energy is the energy you don’t use.
Smart Design and Orientation: Building the path towards energy efficiency lies on the drawing board. Smart architectural design involving orientation can result in maximizing natural light and heating, which eliminates the need for artificial lighting and temperature control. For instance, buildings located on the southern side in the north hemisphere can have sunlight for warmth and light.
High-Performance Insulation: The key player is always having an effective insulation through energy conservation. Thanks to the use of high-quality materials and technologies, buildings could stay comfortable at stable temperature levels while still using far less energy needed for cooling and heating. This includes not just walls, but also roofs, floors, and even the windows as well.
Energy-Efficient Windows and Doors: It is possible to control energy leakage substantially by investing on certain double or triple-glazed windows and well-sealed doors. These elements are vital to maintain the temperature inside and help to minimize the dependency on heating and cooling systems.
Green Roofing and Walls: Green roofs and walls not only look better but also act as natural insulators. They capture heat, reduce stormwater runoff, and improve air quality as they are good options for the urban buildings.

Solar Power Integration: Using Photovoltaic panels for solar energy is a direct way to decrease dependence on non renewable energy sources. Solar Solutions today have gradually become efficient and cost effective, a thing that has seen them be available to a variety of buildings.
Energy-Efficient HVAC Systems: Buildings especially with Heating, Ventilation and Air Conditioning (HVAC) systems are major energy consumers. The cost of upgrading to energy-efficient HVAC systems has great benefits as it results in significantly reduced energy consumption while maintaining comfort levels.
Smart Lighting Solutions: Combination of LED lighting with smart, automated lighting controls that adjusts light depending on occupancy and availability of daylight, results in significant energy savings. This method does not only lead to energy savings but also leads to prolonged service life of your lighting devices.
Water Conservation Practices: Having Low-flow faucets, toilets, and showerheads are some of the water conservation measures together with rainwater harvesting and greywater recycling systems. These approaches minimize the energy necessary for water heating and treatment.

Use of Sustainable Materials: By selectively incorporating materials with low embodied energy and are sustainably sourced, it is possible to reduce the overall environmental impact of a building according to here. Such materials also include bamboo, recycled steel and reused wood or recycled plastic.
Regular Maintenance and Upgrades: Finally, constant maintenance and occasional improvements of building systems are necessary to keep the level of energy efficiency. This encompasses regular inspection of insulation, HVAC systems, as well as assessments to ensure all energy systems are operating at their peak.
To summarize, the journey towards sustainable building spans several dimensions and entails integrated efforts to implement sustainable design, innovative technology, and mindful practices. Through having such practices, we can considerably cut down the environmental footprints of our buildings giving a viable pathway in attaining a greener and more sustainable future.
A tiny home can help cut down your carbon footprint.
The world is growing more and more concerned about carbon footprint, climate change and the very real challenges that come with them.
In the past, people used to talk about climate change as a faraway problem, for future genrations. But with the seas currently rising, storms more frequent and violent, and temperatures soaring at record highs, the problem is undeniably at our doorsteps. And the time to act is now.
One of the biggest ways to combat climate change and contribute to a greener planet is by cutting carbon emissions – the more carbon dioxide in the atmosphere, the worse the ‘greenhouse effect’ is on our planet. And one of the most effective ways of reducing your carbon footprint is by saving as much energy as possible.
Here are 11 to incorporate green living into your everyday life and do your bit for the environment.
Use energy-efficient appliances
A smart thermostat by Nest
There are many reasons toinvest in energy-efficient appliances. The first, of course, is by not using more energy than necessary to power the appliance, less fuel needs to be burnt up to create that energy, so less carbon dioxide gets released into the atmosphere.
The second is that not only do you save energy, but you’ll save money at the same time.
For example, a clunky old boiler will need to work harder to heat your home, whereas a new, A-rated energy-efficient boiler will use less energy to heat the same area.
Opt for LED Lighting
Alongside energy-efficient appliances,energy-efficientlighting can also go a long way in helping to cut carbon emissions.
LED bulbs use far less energy than their incandescent and fluorescent cousins to produce the same amount of light. Not only that, but they last lots longer, too.
Power down and unplug
Putting your computer in sleep mode might feel like a time-saving hack, but it’s actually wasting more energy than you realise. In fact, many electric appliances in your home, like your TV, use small amounts of energy while plugged in and switched on at the mains, even if the device itself is switched off.
Make sure when you’re not using something that you switch it completely off and switch it off at the mains for good measure, especially at the end of each day.
Use smart thermostats
Smart thermostats let you control the heating in your home from wherever you are using a handy app. So instead of worrying about if you’ve left the heating on at home when you’ve already left for work, or don’t want to come back to a chilly home after a long day, you can create a schedule or manually switch the heating on and off from your phone.
Make sure you have proper insulation
Green roofs also insulate. These ones are in the Faroe Islands
Draughty doors and windows work against you to keep the heat in during the winter, and keep the heat out during the summer. This makes your heating system work harder to warm up your living space when it’s cold outside, and your air conditioning system or fans have to run for longer to cool your space down in the summer.
Putting an old scarf at the bottom of a draughty door can help block it, and draught strips dor both doors and windows can be bought online and are relatively inexpensive.
Because heat rises, it’s important to make sure your loft is properly insulated too, so that your home doesn’t lose too much heat through the roof.
Reduce, reuse, recycle
Everyone should be following the above ‘3 Rs of the environment’ to combat overconsumption This cuts the need for the production of new items, which all use up a lot of energy in the manufacturing process.
Use sustainable transportation
It’s no secret that gas-guzzling vehicles are one of the culprits of climate change. But while most of us aren’t likely to hop on a private jet or board a giant cruise ship every day, many of us do have the option to leave our cars at home more often and take the bus or train instead.
The UK government’stransport decarbonisation plan aims to decarbonise all forms of domestic transport by 2050, including reducing domestic aviation and rail to net zero carbon emissions.
Be conscious of your water usage
Water device collects dew
You probably already know how important it is to conserve water. But did you know that water also contributes to carbon emissions?
Water usually needs to be treated before we use it, and then afterwards before it’s returned to the environment. These treatment processes all contribute to the emission of greenhouse gases – so the more water used, the more emissions are generated.
Use renewable energy sources
A Tesla Cybertruck is the easiest way to save money on gas and you can power it up with solar energy from your home
If you’re fortunate enough to afford the initial outlay, solar panels are a great way of generating your own renewable energy at home. If not, some energy firms offer green energy tariffs, and supply energy generated from renewable sources such as wind and solar power.
Support businesses that support eco-initiatives
Businesses have a massive part to play in helping to save the environment. And more and more are making an effort to reduce their carbon footprint by taking part in green initiatives in their day-to-day business, for examplesupporting tree planting initiatives.
Utility Warehouse’s tree-planting initiative sees a tree planted for each new customer who bundles three or more services with them. The ever-growing UW Woodland is located on Bryn Arw in the Brecon Beacons National Park.
Go paperless with bills
As well as planting trees, it’s also important to save them, too, so they can continue to absorb carbon dioxide in the atmosphere. And, of course, once trees are cut down they need to be processed – resulting in yet more emissions.
A multiservice company,Utility Warehouse (UW) makes it easy to switch to paperless bills, which can then be viewed in your online account or in theUW app.
The biggest players in cutting carbon emissions are the big companies of the world. But individuals can do their part, too. And by making at least some of these practical steps a habit in daily life, we can all work together to reduce our carbon footprint, and take steps towards a more eco-friendly world.
Once you’re down with flu, all the standard advice applies: rest, stay warm, drink lots of warm fluids, take something to relieve the symptoms. And have patience. With care and about a week, the bug will fade away.
Before you reach for the usual pain-killers and fever reducers, inspect your spice cupboard. I’ll bet at least a few natural helpers are lurking there. Read more about medicinal spices in our Middle-Eastern Spices and Medicine Guide. Bay leafs, peppercorns and sage will come to the rescue.
Chills. If you’re shivering with chills, try bay leaf tea to warm the body and encourage sweating. Break up a couple of leaves and steep them in hot water for 10 minutes, covered. Stir in a teaspoon of honey and drink. The taste is mild and pleasantly spicy, and the effect warming and comforting. My mother use to make this tea for me when I was a teenager suffering menstrual cramps. It helped, because bay leaf tea encourages blood circulation.
Hoarseness. Losing your voice? Grind 6 or 7 black peppercorns up – you can crush them in a metal or plastic bowl, with the bottom of a bottle. Cover the crushed peppercorns with honey and swallow it all down. The mixture opens up the throat and chest.
Mouth sores and sore throat. Sage infusion is a reliable germ-killer that has an affinity for the mucus membranes. Make a healing gargle with the silvery-green leaves. Steep a teaspoon of finely chopped sage leaves in boiling water, covered. Cool the infusion and gargle with it twice; then repeat twice more over the next 12 hours.
Mucus dripping into the throat while you’re sick is often the cause of infection. Blow your nose often, and gargle with sage the minute you feel that scratch in your throat.
Warning:
Sage has mild hormonal and drying properties. Pregnant and nursing women shouldn’t drink sage tea, nor eat food cooked with large amounts of it. Children, especially girls, should gargle with it, but not attempt to drink it. They won’t want to anyway; sage tea is bitter.
Headache. A cup or two of rosemary tea soothes the tired, achey head, due to its high calcium content. Make an infusion the same way as with bay leaves; steeped in hot water for 10 minutes. Sweeten to taste. Rosemary also clears brain fog for a while.
Pregnant women should avoid rosemary, as it tends to “clean out” the body. But nursing women can benefit from its high calcium content: one-half cup twice daily for no longer than three days.
Keep the vitamin C up with lovely mint tea. My Moroccan friends give their kids mint tea year round, and claim their kids never get runny noses. Drink it hot or cool, made with fresh leaves or dried. Sweeten to taste.
Loss of appetite. Sometimes a sick person just can’t face food. In that case, it’s crucial to stay hydrated with warm teas. Chamomile, being anti-inflammatory and especially soothing, is a great choice. Sweeten to taste and drink freely.
And remember the mystical healing properties of good soup. Chicken or miso soup are light and nutritious. If you’re not up to making your own, ask a friend to fix it.
A winter salad for flu-ey people: Peel an orange and slice it thinly. Layer the slices with fresh mint leaves and if available, sliced tomatoes. Drizzle olive oil and lemon juice over the dish, sprinkling a little salt over all. Or use your favorite salad dressing. The orange, green, and red colors are a delight to the eyes and wake up even a waning appetite. Your body will enjoy a huge hit of vitamin C.
This post doesn’t replace professional medical advice. Consult a doctor if the symptoms are unusually strong or prolonged, or if there’s high fever.
These cheese-filled dates make a piquant addition to a cheese platter. And the recipe can’t be easier: about 10 minutes of preparation should do it, then another 12 or so minutes in the oven. And – you can prepare the dates up to 24 hours in advance and have them ready to pop in the oven just as your guests arrive. Add a tray with small glasses and a bottle of arak, and you have a party. (Try our incredible arak and pomelo cocktail.)
On the family side, this is an indulgent snack for hungry people of all ages, especially those who have to wait for dinner. Serve with a small glass of buttermilk or refreshing aryan for great nutrition and that soothing, satisfied feeling.
It’s easy to understand why dates, coming from hot climates of ancient Mesopotamia, are loved throughout Arabic culture. Food historian Nawal Nasrallah, in Dates, A Global History, writes that the ancients claimed 360 uses for the date palm, including house construction, fences, thatching, irrigation pipes, among others. Nutritious dates have also been considered medicinal. That’s without what first comes to mind when thinking of dates: food. Date syrup, filling for cookies, poultry and meat cooked with dates, date shakes, and much more. And then, surprisingly – dates as an aphrodisiac. Grooms are advised to eat dates before the wedding, to ensure a lively night.
Browsing through her encyclopedic Delights From The Garden of Eden, I came across this romantic quote, where Poet Badir Shakir al-Sayyab compares his love’s eyes to date palms:
Your eyes are like two date-palm groves
at the time of dusk,
Or two balconies from which
the full moon is receding.
So to ensure happy nights, forget the blue pill and nosh up some dates. A little poetry on the side won’t hurt, either.
Dates Baked With Goat Cheese and Walnuts
An easy and unusual way to serve dates, as appetizer or snack.
shallow baking pan
sheet baking parchment
small, sharp knife
1 tablespoon olive oil
2 tablespoons fine dried bread crumbs
24 Medjool dates
125 grams – 1/4 lb. soft goat cheese
12 walnuts
Preheat oven to 375°F. – 180 °C
Line a shallow baking sheet with baking parchment, or lightly oil it.
Warm the olive oil in a skillet, over medium heat. Stir in the bread crumbs and continue stirring until the bread crumbs are golden brown, about 1 1/2 minutes. Spoon the browned crumbs onto a plate and allow to cool.
Make a small lengthwise incision in each date. Carefully remove the pits. Stuff 1 tsp. of the goat cheese into each pit-free date. Place the dates, cheese side up, in a single layer on the baking sheet.
Sprinkle the bread crumbs evenly over the top. (The dates can be prepared up to this point up to 24 hours in advance. Store, tightly covered, in the refrigerator.)
Bake the dates until warmed through, 10 to 12 minutes.
In the meantime, chop each walnut in half.
When the dates are warm and the cheese melting, press half a walnut onto the cheese.
AI deciphers the text of 2,000-year-old charred papyrus scripts, unveiling musings on music and capers.
Student researchers have used machine learning to read text hidden inside charred, unopenable scrolls from the ancient Roman city of Herculaneum. The charred scroll was buried 2,000 years ago by the eruption of Mount Vesuvius.
The newly revealed passages, using software and scanning called virtual unwrapping, discuss sources of pleasure including music, the colour purple and the taste of capers. The team trained an algorithm on tiny differences in texture where the ink had been, based on three-dimensional computed tomography scans of the scrolls.
The scroll is one of hundreds of intact papyri excavated in the eighteenth century from a luxury Roman villa in Herculaneum, Italy. These lumps of carbonized ash — known as the Herculaneum scrolls — are the only library that survives from the ancient world, but are too fragile to open.
Charred papyrus, too fragile to open
The winning entry, announced on 5 February, reveals hundreds of words across more than 15 columns of text, corresponding to around 5% of an entire scroll. “The contest has cleared the air on all the people saying will this even work,” says Brent Seales, a computer scientist at the University of Kentucky, Lexington, and co-founder of the prize. “Nobody doubts that anymore.”
Ancient papyrus scrolls read using AI
Luke Farritor, an undergraduate studying computer science at the University of Nebraska-Lincoln, used the crackle to train a machine-learning algorithm, revealing the word porphyras, ‘purple’, which won him the prize for unveiling the first letters in late October. An Egyptian PhD student in Berlin, Youssef Nader, who followed with even clearer images of the text, came second.

The content of most of the previously opened Herculaneum scrolls relates to the Epicurean school of philosophy, and seems to have formed the working library of a follower of the Athenian philosopher Epicurus, who lived from 341 to 270 BC, named Philodemus.
AI looks at Vesuvius papyrus scroll to look inside
The new text revealed in the contest doesn’t name the author but, from a rough first read, researchers predict it is by Philodemus. As well as pleasurable tastes and sights, the scroll includes a figure called Xenophantus, possibly a flute-player of that name mentioned by the ancient authors Seneca and Plutarch, whose evocative playing apparently caused Alexander the Great to reach for his weapons.
Researcher Seales has been trying to read these concealed texts for nearly 20 years. His team developed software to “virtually unwrap” the surfaces of rolled-up papyri using three-dimensional computed tomography (CT) images. In 2019, he carried two of the scrolls from the Institut de France in Paris to the Diamond Light Source particle accelerator near Oxford to make high-resolution scans.
Seales team read Dead Sea scrolls from the Ein Gedi region in Israel. The Dead Sea Scrolls, also called the Qumran Caves Scrolls, are a set of ancient Jewish manuscripts from the Second Temple period. They were discovered over a period of 10 years, between 1946 and 1956, at the Qumran Caves near Ein Feshkha on the northern shore of the Dead Sea, Israel.
Wood has been a popular building material for thousands of years. It can offer a number of advantages; it’s easy to procure, strong, affordable and sustainable. It also looks fantastic and is available in a range of colours, tones and textures.
However, one downside of wood is that it can be prone to degradation. This can be prevented, but it involves providing a level of care. How can you protect your external wooden structures from the elements? Let’s find out.
Keep Your Structures Clean
When it comes to protecting your external wooden structures from the elements, the most important thing you can do is keep them clean. Being outside, these structures can quickly accumulate dirt and grime. It’s important to stay on top of things and prevent things from building up to unmanageable levels.
Whether it’s a wooden fence or a shed, regular cleaning will help prolong the life of the material. Move away any leaves or vegetation that have gathered around the structure, as this can be a breeding ground for mould and bacteria, which can cause wooden structures to rot and degrade rapidly.
Paint Wooden Structures
Another effective way of protecting your outside wood structures against the elements is to paint them. This will give them a protective coating that can keep out moisture, keeping them in good condition for a longer period of time.
Painting has an added bonus in that it makes your wooden structures look much more attractive. You can choose from a range of colours to brighten up your outdoor space and make things more visually interesting.
Use a Wood Preservative
Imagine how much condensation builds up in this tiny home when the wood fire is burning? Make sure you use the right wood protection to avoid mould damage which stains wood black.
If you’re looking to give your external wooden structures even more protection, use a wood preservative. These chemicals can be applied directly to the wood itself or over paint and will safeguard the material against moisture, bacteria and other harmful pollutants.
You can pick up wood preservative products and otherbuilding supplies from Mcblair as an example. Use wood preservatives and your outside structures will last for many years to come, whatever the weather.
Check for Signs of Wear and Tear
Cleaning your structures and using paint and preservatives are important when protecting materials against the elements, but you also need to be proactive and constantly look out for signs of wear and tear.
Small areas of damage can quickly spread, and before you know it you could be faced with a large repair job, or even having to replace a structure entirely. Inspect your structures regularly to prevent this from happening. If you spot any damage, take action quickly before it gets any worse.
Don’t just check areas you can see. You need to inspect the entirety of your structures, including roofs and less accessible spots. Thoroughly and regularly checking for signs of wear and tear is one of the most effective ways to protect your external wood structures from the elements.
Conclusion
To protect your outside wood structures from the elements, keep the material clean at all times, use paint and wood preserver and regularly inspect for signs of wear and tear.
Corals don’t do well in shipping lanes. They don’t do well when people step on them or when they are met with oil spills. Coral reefs the world over are threatened and now an international team is looking to deep dive into the research that could impact laws around them. As countries like Saudi Arabia ramp up tourism in the Red Sea with Neom and The Line, and Vision 2030, and as the Houthis threaten to blow up oil tankers, the world wants to know: how do stressors like light and noise impact the reefs?
Prof. Oren Levy, Director of the Laboratory for Molecular Marine Ecology at Bar-Ilan University, is a member of a newly-launched EU project to improve our comprehension of how biodiversity is being impacted by Light and Noise Pollution (LNP) in aquatic environments such as rivers, lakes, coastal and offshore waters.
Funded by the Horizon Europe program, AquaPLAN (Aquatic Pollution from Light and Anthropogenic Noise: Management of Impacts on Biodiversity) aims to quantify the combined impacts of LNP on aquatic biodiversity in European waters and facilitate the implementation of empirically sound strategies for managing these pollutants through novel interdisciplinary approaches.

Prof. Levy’s contribution to the project focuses on the unique environment of tropical coral reefs in the Red Sea, where he examines the impact of light pollution on vital ecological aspects. His research targets the synchronization of coral spawning, a critical event for reef regeneration, which can be disrupted by artificial lighting. Additionally, he studies how light pollution affects the behavior of tropical fish and the colonization patterns of invertebrates in light-polluted areas, providing insights into the broader ecological impact.
Alongside colleagues from the consortium, Levy also extends his research to include the effects of noise pollution on these marine ecosystems, exploring how both light and noise pollution jointly influence coral reefs, fish behavior, and invertebrate colonization.
Understanding how LNP affects aquatic biodiversity has dramatically improved in recent decades. Evidence suggests that these effects are prevalent globally, in all types of aquatic ecosystems, from rivers and lakes to the seafloor. Despite growing knowledge and access to a range of technologies, best practice methodologies and policy interventions, there are still many critical knowledge gaps that, if addressed, would allow us to better manage and reduce these impacts.

Project coordinator Prof. Elena Maggi from University of Pisa said, “Currently, existing regulations on the emission of Artificial Light At Night (ALAN) and anthropogenic noise are highly fragmented in inland, coastal and offshore waters. Moreover, we still need good datasets to understand how to monitor, protect and restore aquatic biodiversity effectively.”
AquaPLAN will run for four years. It is coordinated by the University of Pisa (UNIPI) and comprises a multi-actor, transdisciplinary team of 13 organizations from nine countries. The consortium recently gathered in Pisa, Italy for the project’s kickoff meeting.
A green roof is a beautiful idea for cities. They feel good, look good, they clean the air and reduce temperatures inside in the summer, increase them in the winter. They are good for the birds and the bees. But green roofs are cut off from the great web of information and possibilities found in soil attached to the earth. Scientists have a new idea: Mycorrhizal fungi.
In the US green roofs are typically planted with non-native plants in sterile soils, and their effectiveness declines over time. A Dartmouth-led research team set out to determine if managing green roof soil microbes could boost healthy urban soil development, a methodology that could be applied to support climate resilience in cities.
The team created an experimental green roof in Chicago to test how enhancing soil with native prairie microbes would change the soil microbial community over time. They were particularly interested in tracking the presence of beneficial mycorrhizal fungi.
Mycorrhizal fungi are well-known to live in roots and support plants in a symbiotic underground relationship, delivering nutrients and water to them in exchange for plant sugars. Mycorrhizal fungi could be particularly helpful to plants in green roofs that have to endure high temperatures, intense sun, and periodic flooding.
The researchers added soil rich with native mycorrhizal fungi obtained from a local restored prairie, referred to as “inoculum,” to the experimental green roof’s soil. They planted inoculated and untreated soil with native prairie plants and green roof succulents. Over two years, the team tracked changes in the mycorrhizal fungal community of the green roof. They also compared the green roof fungal species identified to those present in the inoculum and in the air.
Their findings demonstrate that active management of green roof mycorrhizal fungi accelerates soil development faster than if mycorrhizal fungal communities are left to passively reestablish on their own. Green roofs treated with mycorrhizal fungi foster a more diverse soil community that is more likely to support long-term green roof sustainability, according to the results published in New Phytologist.
“In this urban rooftop setting, we saw more diversity in the fungal communities of the inoculated soil,” said lead author Paul Metzler, soil ecology lab manager in the Department of Environmental Studies at Dartmouth. “The long-term and consistent effects of the inoculum were quite surprising, as it’s not necessarily something you would expect when working with such small microorganisms.”
Using a molecular technique called “DNA metabarcoding,” which enables the identification of multiple organisms in one sample, the researchers could identify fungi present in the green roof soils as well as potential sources of these fungi. Many fungi came from the inoculum while other species got there through some other vector such as wind.
The co-authors state that their study was different than most of its kind, as few studies track mycorrhizal community shifts over time post-inoculation and even fewer attempt to track the sources of species pools. The team also had a number of species in their green roof that likely arrived via unmeasured vectors such birds, insects, or even rats.

Still, the most diverse fungal communities were those that had been treated with the inoculum, illustrating how mycorrhizal fungi could be used to improve soil health in green roofs. The results suggest that active management of soil microbial communities is effective and worth the effort and resources in cities.
“Green roofs have a shelf life and they’re not always the self-sustaining ecosystems that we think they are,” says senior author Bala Chaudhary, an associate professor of environmental studies at Dartmouth. “They can be beneficial to urban areas but tend to lose their efficacy over time.”
While green roofs are marketed as “set it and forget it,” the co-authors explain that ecological thought should be incorporated into their design, construction, and maintenance to maximize the benefits and role that green roofs play in the climate resilience of urban areas.
“Our cities could be a window into the future,” says Chaudhary. “They are experiencing the impacts of climate change—warming temperatures and increased drought and flooding—in an intensified way, which make them a great microcosm to study some of these impacts below ground.”

A green bedroom starts with an eco mattress like this one from Avocado
Greening your life, doesn’t require you to overhaul your house.There are small ways you can green your kitchen and your bathroom; we’ve even started a series for greening your baby. Let’s take a look at the bedroom.
When John Lennon and Yoko Ono recorded the song Give Peace a Chance from their hotel bedroom in Montreal during a 10-day honeymoon bed-in, it was hardly random that they chose their sleeping quarters as the place to launch their political campaign against war: “We are just looking for a little peace,” John wrote in a song about that time.
For usual folk, the bedroom is a room set aside for life’s most intimate moments – which includes the obvious, plus sleeping, dressing, reading and even working (if you have a laptop).
Times have changed since Lennon and Ono started their not-so-private revolution in the bedroom. The spirit of activism has changed too. Today each of us knows that to stay healthy and keep the planet green, every one of us needs to nurture and develop our own inner-activist.
And the bedroom, where we spend at least one-third of our time, is a great place to start a mini-green revolution.
Some studies have shown that people are more exposed to toxins and nasty chemicals inside the house than on city streets. For that reason it is wise to make sure that if you are about to purchase sheets, furniture or mattresses you look into ones that are low emitters of formaldehyde and other chemicals and glues.
Stores around the world, many of which sell through the Internet, can supply you with non-emitting natural paints and thinners to help you create soft and clean walls that don’t interfere with your bodily processes as it slumbers off into the night. And if you can recommend any to buy in Israel, please post them in the comments section.
Entering dreamland and consolidating our daily experiences into memory are two very important processes that occur in the bedroom. And research has shown that our state of sleep today is much different than it was for our ancestors just a century ago, says sleep expert William Dement, M.D., Ph.D., of the Stanford University Sleep Research Center in The Promise of Sleep (Delacorte Press, 1999).
Our great-great grandparents slept on average 1.5 hours more per night, he says.
Before the advent of the electric light bulb, our ancestors drifted off not long after the setting sun and rose with the cock’s crow in the morning. Today, busy days and unhealthy sleeping environments mean that we often don’t have enough sleep.
“If you can see your hand after the lights are turned out, your bedroom is too light,” says Carol Venolia, a US-based ecological architect who has written the book, Natural Remodeling for the Not-So-Green House published in June 2006.
Scientists warn, Venolia explained, that if there is too much light in your bedroom, cast from streetlights, light from the bathroom etcetera, melatonin production in our bodies is disturbed which can lead to irritability and long-term health problems.
Consider soft lighting in your bedroom and avoid checking emails just before you plan to doze off. Even the strong light from the screen can give your body a jolt of light, and can have the same effect as drinking a cup of caffeinated coffee just before bed.
Houseplants can aid to your peace of mind and ones like cheese plants don’t just produce oxygen, they filter out a lot of pollutants and toxins.
(Other toxins to avoid are mothballs, used in closets to prevent moths from chewing your wool sweaters. Instead use cedar chips, rosemary, mint and peppercorns, added to cedar oil. Stored in your cupboard, it will keep the moths at bay.)
Tiled floor for the bedroom. Maybe gently heated underneith?
Pay attention to the design in your room. You want to be given the feeling of being cradled and protected when sleeping. Avoid clutter and bright colours. The Waldorf or anthroposophic movement has some great color schemes to play with.
Feng Shui experts have known this for some time. They also say to face your bed towards a door and away from drafts of the window. A strong headboard behind you is necessary for absorbing negative energies.
Nader Khalili, a visionary architect from Iran, now in California, builds “bedwombs” in his home. He digs out small shells from the side walls of his naturally crafted homes – shells that are big and deep enough for someone to sleep inside.
“It is just like a pouch that becomes a bedwomb,” he says in an online interview.
“I see them as bedwombs,” says Khalili, “because they are more in line with our own bodies. They are organic forms. You don’t see any straight lines in your body, all these angles and forms, and so on. Somewhere along the way the history of humans became very square, angular!”
While not all of us have the desire, time or resources to build a “Khalili bedwomb,” there are still some basic and necessary things to do, in order to keep the bedroom a healthy and protected environment.
Sleep as far away as possible from the noise of the street and from electric equipment that makes noise or emits electromagnetic radiation.
Experts say that keeping the heat down in the bedroom (to 65 degrees Fahrenheit) is healthier than jacking up the radiator. Avoid the use of electric blankets and excessive heat that you don’t really need and the planet will thank you.
Also consider using energy-saving bulbs. They will keep your energy bills low and can last up to 12 times longer than the conventional bulbs.
Choose some natural looking pottery elements to fill in some gentle corners of your room.
How does your bed feel? Is it comfortable? Watch out for dust mites and mold. Keep the room clean, fold down the sheets on your bed so it can air out and clean your duvet and blankets every six months to get rid of skin scales and house dust mite faeces.
Some colour theorists believe that soothing colours will help put your body into a sleepy frame of mind. Lavender, blue, or light green are among the most popular.
In the morning, take it slow and let yourself awaken gradually with the sun. (Eco Rabbi might say different, because the Torah says one should awake like a lion!)
A simple method for destroying PFAS using hydrogen and UV light
An insidious category of carcinogenic pollutants known as “forever chemicals” or PFAS may not be so permanent after all University of California, Riverside, chemical engineering and environmental scientists recently published new methods to chemically break up these harmful substances found in drinking water into smaller compounds that are essentially harmless.
Theprocess infuses contaminated water with hydrogen, then blasts the water with high-energy, short-wavelength ultraviolet light. The hydrogen polarizes water molecules to make them more reactive, while the light catalyzes chemical reactions that destroy the pollutants, known as PFAS or poly- and per-fluoroalkyl substances.
This one-two punch breaks the strong fluorine-to-carbon chemicals bonds that make these pollutants so persistent and accumulative in the environment. In fact, the molecular destruction of PFAS increased from 10% to nearly 100% when compared to other ultraviolet water-treatment methods, while no other undesirable byproducts or impurities are generated, the UCR scientists reported in a paper recently published in the Journal of Hazardous Materials Letters.

What’s more, the cleanup technology is green.
“After the interaction, hydrogen will become water. The advantage of this technology is that it is very sustainable,” said Haizhou Liu, an associate professor in UCR’s Department of Chemical and Environmental Engineering and the corresponding author of the paper.
PFAS are a family of thousands of chemical compounds characterized by fully fluorinated carbon atoms with stubbornly strong chemical bonds that last indefinitely in the environment – hence the moniker “forever chemicals.”
These compounds came into widespread use in thousands of consumer products starting in the 1940s because of their ability to resist heat, water, and lipids.
Examples of PFAS-containing products include grease-resistant paper wrappers and containers such as microwave popcorn bags, pizza boxes, and candy wrappers; stain and water repellents used on carpets, upholstery, clothing, and other fabrics; cleaning products; non-stick cookware; and paints, varnishes, and sealants, according to the U.S. Environmental Protection Agency, or EPA.
Since these compounds persist and accumulate in the environment, dairy products and meat from animals exposed to PFAS are also sources of these compounds. In fact, PFAS are so ubiquitous, scientists have found them in the blood of nearly all people tested, according to a California legislative analysis. Germans find them in their drinking water.
Studies have linked exposure to certain levels of PFAS to many ill health effects, including increased risk for prostate, kidney, and testicular cancers, according to the EPA.
Exposure to these pollutants also may lead to decreased fertility or increased high blood pressure in pregnant women, developmental effects or delays in children, low birth weight, and accelerated puberty. PFAS compounds also have been found to compromise the immune system’s ability to fight infections and to interfere with hormone function.
Because of these health effects, federal and state officials are promulgating new cleanup standards for PFAS in drinking water and in groundwater below or emanating from toxic cleanup sites.
The EPA this fall took public comments on plans to designate two PFAS substances — perfluorooctanoic acid and perfluorooctanesulfonic acid — as hazardous substances under the federal Superfund toxic site cleanup laws. If this regulation is approved, it would hold polluters accountable for cleaning up their contamination.
In California, the State Water Resources Control Board issued an order this year for public drinking water providers to test for PFAS. If the testing exceeds specified levels, the providers must issue public notifications, remove the source or sources, or treat or blend the water.
“We are optimizing it by trying to make this technology versatile for a wide range of PFAS-contaminated source waters,” Liu said. “The technology has shown very promising results in the destruction of PFAS in both drinking water and different types of industrial wastewater.”
The other option entirely is to find clean, fresh springwater and gather water at the source.
