Startup uses 3D prints to build “Urban Reefs” for better Air Quality

Publicerad denFörfattareNoah Duker

The Dutch startup “Urban Reef” uses 3D printers with renewable materials to create sculptures that are planted with a variety of mosses, mushrooms, and other plants. These help clean the polluted air of big cities with their natural processes like photosynthesis. As of now the project is still in development but already shows promise as sustainable solutions for improving air quality are hard to come by. 
Amsterdam – Bio inclusivity is the word of the day. Cities have, ecologically speaking, come closer to deserts than any other biome they might have been built upon. Parking spaces, multilane highway systems and other concrete infrastructure have driven a large chunk of wildlife as far away from the city as possible. Despite the efforts of numerous city councils across the world, this model of car dependent cities and fossil fuelled economies has led to poor air quality reaching health endangering levels. 
Combating dangerous air pollution with “Urban Reefs” made of sustainable sculptures and plants
This is where urban reefs come in: the young studio based in the Netherlands has started up a variety of projects, promising improvements when it comes to air quality and biodiversity in cities. Similar to what reefs are for shallow ocean biomes, these urban reefs, are supposed to be an oasis for different species of plants and fungi. Sprinkling these reefs across cities would be a cheap and space efficient way of making cities more liveable.

“Urban reefs” is using 3D printers filled with biodegradable, “living” material, allowing plants to easily grow on the surface. The method allows for cheap and sustainable ways to produce all kinds of things. In their case, shell-like sculptures to house the plants. At this point, their team is focused on a variety of improvements, like improving the materials used and the shell designs, as well as bio receptivity research, looking at what conditions are favourable for growing communities of organisms in an urban environment. 
The step away from concrete is important considering that the sand used for concrete is getting rather scarce due to a boom in the construction industry around the globe. Concrete needs sand as a main ingredient, but not every kind of sand is usable, dessert and ocean sand is too smooth to be used for industrial purposes. 
Air pollution responsible for growing cancer rates in cities
When it comes to air pollution, it is important to distinguish between particular matter (pm) and coarse dust. Particular matter are particles up to 2.5 micrometres, coarse dust has a size up to 10 micrometres. The danger of air pollution lies with the particular matter, emitted by cars, tires, coal power plants and other methods of heating. According to the World Health Organization (WHO), being subject to large amounts of air pollution, especially pm, over time can lead to “increased risk of respiratory infections, heart disease and lung cancer”. 
But what causes air pollution? The obvious culprit is cars, not just in burning fuel, but also in not so obvious ways, like wearing down tires that emit small plastic particles into the air and further into our lungs. With results like this, it’s no wonder that projects to help filter these particles out of the air are in high demand. The plants, also subject to the same pollution, have better capabilities when it comes to filtering these harmful microscopic particles than humans.  Läs mer…

Los Angeles implemented a new tax on luxurious real estate to finance affordable housing and combat homelessness

Publicerad denFörfattareNoah Duker

Los Angeles implemented a so-called “mansion tax”. At a rate of 4% for real estate purchases between 5 and 10 million dollars and 5.5 percent for properties over ten million dollars. All in all, the tax is expected to bring in about 670 million dollars of revenue. The money is mend to finance affordable housing and thus preventing people from becoming homless.  
The tax, officially known as “Measure ULA” was agreed upon by the state legislator after a referendum in November 2022 as close to 60% of voters cast their ballot in favour of the proposed law. Los Angeles being the city with the highest number of homeless people in the country, it’s little wonder that such a tax comes to fruition. California in general is also known as the second most expensive state when it comes to real estate, only being topped by Hawaii. 
Under the new tax, a millionaire selling a house worth 5 million dollars would have to pay 200 thousand dollars to the government. To put the necessity of action in the city of LA into perspective, the recent crises have made the number of homeless people skyrocket to around 42,000 people in February 2022. In 2016 the number was closer to 28,000 people without a home according to an article published in the New York Times.
Other estimates by the “US department of housing and urban development” put the number of homeless people in the LA at a staggering 65.111 people.

“Mass Panic”: Real Estate Owners get creative in trying to avoid the new Taxes
Despite the relatively low sum of tax money in comparison to the enormous profits made in the real estate market, millionaires and celebrities sought for evermore creative and desperate ways to avoid contributing to improving societal living standards. According to “The Guardian“, one desperate super rich homeowner of a 16.5-million-dollar mansion was going as far as to gift a supercar to whoever buys his house, just to get out of paying around 900 thousand dollars in tax.
Others are taking different approaches to avoid paying taxes. A legal challenge has been put before court, claiming the tax violates the Californian constitution. The outcome of the challenge is, as of now, still open, and it will very likely take a while until any result comes of it. 
The Tax would only affect 4 Percent of the Real Estate Transactions in LA
According to the luxury real estate platform “redfin” the median selling price for property in California is just short of a million dollars. It is hovering around 900 thousand dollars. The tax therefore would only affect about 4% of real estate transactions in the city.
Interesting claims come from real estate agents working for the super-rich. The tax is set too low, as 5 million dollars for a home does not qualify as a mansion. “Five million dollars is certainly not luxury. It’s a nice house, in a nice area. It’s not what most people would consider a luxury house in a prime area”, says real estate agent Scott Tamkin.
Critics launch massive PR campaign to sway Public Opinion
But he is not the only real estate agent trying to tell the average person that a five-million-dollar home (about 4000 square foot in Beverly Hills according to Josh Altman, real estate agent and reality TV star) is not a luxury. A massive PR campaign seems to have been launched to sway public opinion against the tax with multiple large US news outlets writing pieces against the proposed tax, despite the scientific, political, public support for the law.

The new Tax will bring in about 627 Million Dollars
It’s estimated that the tax will bring in about 627 million dollars, according to an article published by the Guardian. This still enormous sum is almost 400 million dollars short of the sum initially expected being a billion dollars, but still more than triples the amount of revenue collected from the before active transfer tax, which is raking in about 200 million dollars per year.
Multiple universities and analysts, above all the University of California (UCLA) have recently come forward to counteract the multi-millionaires PR offensive to roll back the tax. They are saying that the money collected and the impact on the housing market will really help improve the homelessness crisis in Los Angeles.  Läs mer…

Swamps as a climate saver: Ireland stores tons of CO₂ through 33,000 hectares of new peatlands

Publicerad denFörfattareNoah Duker

Ireland is reforesting its swamps and bogs in a bid to fight climate change. Although marshlands cover only three percent of the earth, they store 25 percent of the world’s CO2. So far, around 8100 hectares on the “green island” have been flooded with water. The “watering” is intended to create optimum conditions for new peat land. Experts believe that the “renaturation” project will store enormous amounts of climate-damaging greenhouse gases.
Peatlands are considered to be the ecosystem with the greatest storage potential for CO₂. When a plant dies, the CO₂ stored in it is released into the water or into the marsh soil as it decays, rather than into the air. Bogs and marshlands are therefore true climate protectors!
Trees store CO₂ and release oxygen This process is called photosynthesis. When trees die and rot, they release the remaining CO₂ into the environment, especially into the air. However, if a tree falls into a swamp, the CO₂ is not released into the air but stored in the water and soil. If the swamp dries up, and thus also the CO₂-containing mixture, peat is formed. Over thousands of years, a well-known raw material is created from it: coal!
Ireland is reforesting swamps and peatlands to fight climate change
Until the industrial revolution, almost one fifth of Ireland was covered with peatlands. From the 1850s until today, people have destroyed large parts of Ireland’s nature – that is, besides marshlands, also countless forests. The partly state-owned company “Bord na Móna” wants to revive nature and make Ireland the green lung of Europe to fight climate change. For this reason, they are filling 33,000 hectares of alluvial land with water over the next few years. They also want to reintroduce native species of plants and animals that have been driven or wiped out over the years. Currently, just under a quarter, or 8125 hectares, has been “reforested.”
How Ireland’s marshlands were destroyed and rebuilt
The reason for the poor condition of Ireland’s peatlands is historical. The tradition of “peat cutting” has been preserved and carried on for generations. The peat, when dried, is a good fuel. For the economy, especially during the industrialization, the peat was in great demand because it could be found everywhere on the island and was therefore very cheap. Peat was also used to heat the houses in Ireland.
Another reason for the large-scale drainage of the Irish peatlands is agriculture. During the Industrial Revolution, Ireland developed not only railroads and cities, but also agriculture on a large scale. For the cultivation of food, large areas of marshland were destroyed.
Even at the beginning of industrialization, the destruction of the marshes was already underway: by the end of the 19th century, Ireland was more industrialized than the whole of Austro-Hungarian Empire or Spain, two countries that were significantly larger in terms of area and population. The partly state-owned Irish company “Bord na Móna” and others now wants to declare war on environmental destruction and make the “emerald isle” live up to its name again.

Breakthrough: New gel shown to be effective for brain tumour treatment

Publicerad denFörfattareNoah Duker

A new “miracle” gel shows great promise for brain tumour treatment during lab tests at Johns Hopkins University. The gel is used to treat one of the most aggressive forms of brain tumour, glioblastoma, leaving patients with a diagnosed life expectancy of 12 – 18 months. The new treatment is used post-surgery to fill the spaces left by the removed tumour, hindering it from regrowing!
Professor Cui, an expert on chemical and biomolecular engineering, and his team say that the gel could even be used to treat areas of the brain that surgery might not be able to reach. Other than that, tests on infected mice have shown that the gel removed 100 percent of the aggressive tumour, freeing them from certain death. Furthermore, the gel seemed to create an immune reaction that allowed surviving mice, who were reinfected with glioblastoma, to fend off the tumour on their own using only their immune system. It also showed signs of improving immune memory, leading to a generally strengthened immune system post treatment. 
Despite the breakthrough, the medical procedure is still risky since brain surgery is still required for the gel to work effectively, having to be applied directly to the brain. Using the gel without surgery first led to a survival rate of around 50 percent.

For those interested in the science behind the miracle: the gel uses a combination of nano-sized filaments, extracted from the approved drug paclitaxel which then transports the antibody called aCD47. The mixture then expands upon the crevice that the tumour left, leaving the aggressive cancer with no room to regrow, thereby killing it off. 
Brain Tumour Treatment: Glioblastoma – aggressive and everywhere
There are a few reasons why Glioblastoma is so dangerous. The tumour is fast-growing and infects surrounding tissue, which can make surgical removal even harder. Another reason is the brain’s own defence mechanism, known as the blood brain barrier or BBB for short. This barrier normally hinders harmful substances from entering the brain, but also does the same for cancer treating drugs, leading to treatments being less effective.
Glioblastoma’s location in the human brain also doesn’t help with its treatment as it is usually located in the cerebral hemispheres of the brain, which are responsible for critical functions such as movement, sensation, and cognition. This makes surgical intervention more risky, as injuring healthy brain tissue can lead to serious neurological problems.
Science deniers and conspiracy believers are trying to push an anti-science agenda
In the past century, medicine has come a long way. From the times of experimental treatments using drugs like heroin and cocaine to the first effective polio vaccine developed in 1955 by Dr. Jonas Salk, ending the terror of infantile paralysis.
The medical developments of the past few years, however, have been even more marvellous. Science managed to make breakthrough after breakthrough. From healing patients with HIV, a sickness that used to be untreatable and therefore a death sentence, to stopping a global pandemic within two years of the outbreak.
Modern science is leading humanity to longer and healthier lives. But the security and development that scientific research has brought to fruition has come under attack as of recent. Science deniers and conspiracy believers are trying to push an anti-science agenda, smearing scientific fact as wrong or “fake news”, attesting that scientists are either bought by a mysterious elite or some other delusion, just because science does not back their opinion on certain topics. In today’s age of information, having sources and research is key to being informed. Therefore, it is necessary to honour and protect proper scientific research from delusional attacks such as those we saw during the covid pandemic. Because without modern science, life as we know it would be a lot shorter, and a lot less enjoyable, as the case of Glioblastoma makes evermore clear. Läs mer…

Amsterdam Airport Schiphol bans Private Jets and Night Flights

Publicerad denFörfattareNoah Duker

The private jet ban is set to into effect at the end of 2025. This will lead to “more quiet, clean and better air travel” an airport official said in a statement. Other than that, larger and therefore louder aircraft like the Boeing 747 should no longer be commissioned to land at the Dutch airport. Local inhabitants and climate activists welcome Schiphol’s move towards better quality of live in the Amsterdam suburb. The wake of this decision now echoing through Europe as more cities want to push for similar policies in the future.
Speaking in numbers, this would mean about 10,000 fewer aircraft per year to land at Schiphol, their flights being cancelled with the ban. Recently the government also implemented directives for the airport to reduce the flights from 500 to 440 thousand flights, cutting an additional 40 thousand flights, starting November 2023. 
“For too long, we have only thought about growth and not enough about the associated costs. We need to be sustainable for our employees, the environment and the world.”, Says Ruud Sondag, CEO Royal Schiphol Group.

Lawsuit against guidelines – airlines fear reduced profits
Travel agencies and Airlines have complained about the changes. The Dutch Airline KLM, who’s main airport is Schiphol, was surprised, claiming that they had wished for coordinated action across the entire air travel industry. But the lack of actual plans stemming from big airlines might explain why Schiphol’s decision not to wait.
The shrinking of flight numbers at Schiphol was followed by a lawsuit by KLM and four other airlines in fear of having reduced profits. Early April 2023, a Dutch court now overruled the directive due to an issue regarding formalities in the law-making process. 
Climate activists are disappointed about the court’s ruling, setting back the efforts of CO2 reduction in the Netherlands drastically. Their hopes now lie with the airport’s lone push to at least save a fourth of the CO2 intended by the government.
Private jets as climate killer – Germany to consider ban in the future
German air travel expert Sussane Menge sees private jets as a “great climate injustice” and calls for airports in Germany to implement similar directives to Schiphol to combat rising CO2 emissions. 
“It is no longer plausible that many people are now combating global warming by insulating houses and replacing heating systems, while a small minority is pumping out jet fuel as if there were no tomorrow.” – German air travel expert Susanne Menge. 
Now the German Greens have announced that they are considering proposing a similar with support from opposition party “die Linke” (the Left) though the future of this legislation is unclear.
Most wealth – Most emissions
And the numbers add up, considering that in 2019, a year before the Private jet boom properly kicked off, private jets already accounted for 899,000 metric tons of carbon dioxide (CO2). In comparison, in the same year, the CO2 emissions on a global average per person accounted for about 4.78 tons per year.

Considering these facts, it gets even more baffling when one considers that these 899 thousand tons of carbon dioxide is emitted by just about 22 thousand jets. Meaning that these approximately 22,000 private aircraft owners emit equally to about 188,000 people. And that’s only with their jets, accounting for other luxuries, these numbers can rise up to a staggering 3 million tons per year for the top 1 percent.
A person with average carbon emission would take more than 627 thousand years to produce the amount of CO2 a billionaire emits in a Year. Considering the shrinking CO2 budget, the rising temperatures and growing wealth inequality, considering bans like this might be a necessity all over Europe in the future. Läs mer…
