The origins of writing may be traced to clay tablets in Iraq

0

 Researchers have uncovered links between the precursor to the world’s oldest writing system and the mysterious, intricate designs left behind by engraved cylindrical seals that were rolled across clay tablets about 6,000 years ago.The origins of writing in Mesopotamia (the birthplace of the Jewish Bible’s Abraham and which is modern day Iraq) lie in the images imprinted by ancient cylinder seals on clay tablets and other artifacts, say a research group from the University of Bologna.

The researchers have identified a series of correlations between the designs engraved on these cylinders, dating back around 6,000 years, and some of the signs in the proto-cuneiform script that emerged in the city of Uruk, located in what is now southern Iraq, around 3000 BCE.

The study, published in Antiquity, opens new perspectives on understanding the birth of writing and may help researchers not only to gain new insights into the meanings of the designs on cylinder seals but also to decipher many still-unknown signs in proto-cuneiform on pottery vessels.

“The conceptual leap from pre-writing symbolism to writing is a significant development in human cognitive technologies,” explains Silvia Ferrara, professor in the Department of Classical Philology and Italian Studies at the University of Bologna.

“The invention of writing marks the transition between prehistory and history, and the findings of this study bridge this divide by illustrating how some late prehistoric images were incorporated into one of the earliest invented writing systems.”

Among the first cities to emerge in Mesopotamia, Uruk was an immensely important center throughout the fourth millennium BCE, exerting influence over a large region extending from southwestern Iran to southeastern Turkey.

In this region, cylinder seals were created. Typically made of stone and engraved with a series of designs, these cylinders were rolled onto clay tablets, leaving a stamped impression of the design.

Starting in the mid-fourth millennium BCE, cylinder seals were used as part of an accounting system to track the production, storage, and transport of various consumer goods, particularly agricultural and textile products.

It is in this context that proto-cuneiform appeared: an archaic form of writing made up of hundreds of pictographic signs, more than half of which remain undeciphered to this day. Like cylinder seals, proto-cuneiform was used for accounting, though its use is primarily documented in southern Iraq.

“The close relationship between ancient sealing and the invention of writing in southwest Asia has long been recognized, but the relationship between specific seal images and sign shapes has hardly been explored,” says Ferrara. “This was our starting question: did seal imagery contribute significantly to the invention of signs in the first writing in the region?”

To find an answer, the researchers systematically compared the designs on the cylinders with proto-cuneiform signs, looking for correlations that might reveal direct relationships in both graphic form and meaning.

“We focused on seal imagery that originated before the invention of writing, while continuing to develop into the proto-literate period,” add Kathryn Kelley and Mattia Cartolano, both researchers at the University of Bologna and co-authors of the study.

Researchers have uncovered links between the precursor to the world’s oldest writing system and the mysterious, intricate designs left behind by engraved cylindrical seals that were rolled across clay tablets about 6,000 years ago.

“This approach allowed us to identify a series of designs related to the transport of textiles and pottery, which later evolved into corresponding proto-cuneiform signs.”

This discovery reveals, for the first time, a direct link between the cylinder seal system and the invention of writing, offering new perspectives for studying the evolution of symbolic and writing systems.

“Our findings demonstrate that the designs engraved on cylinder seals are directly connected to the development of proto-cuneiform in southern Iraq,” confirms Silvia Ferrara. “They also show how the meaning originally associated with these designs was integrated into a writing system.”

Etihad Rail, the developer and operator of the UAE National Rail Network, signed a landmark agreement with Emerge, a joint venture between Abu Dhabi Future Energy Company PJSC – Masdar and EDF Group to solarize the railway network’s freight terminal in Ghuweifat.

The total installed capacity is comprised of a 600 kWp ground-mounted solar PV system in addition to a 2.56 MWh battery energy storage system (BESS), and upon completion is expected to generate up to 85% of the terminal’s electricity consumption.

The agreement was signed by Ahmed Al-Yafei, CEO of Etihad Rail Infrastructure and Eng. Abdulaziz AlObaidli, Chairman of Emerge, and witnessed by His Excellency Shadi Malak, CEO of Etihad Rail, Mohamed Jameel Al Ramahi, CEO of Masdar, and Luc Koechlin, CEO EDF Middle East.

Under the terms of the agreement, Etihad Rail will leverage Emerge’s technology to generate solar power to supplement its Ghuweifat freight terminal with renewable energy during daylight hours, thus, offsetting night-time energy consumption as well as reducing CO2 emissions by more than 8,500 tons over the duration of the contract.

We are leading the charge in the shift to a low-carbon and energy efficient economy. By collaborating with Emerge and initiating the transition to solar power, we are not only reducing our environmental impact, but also building greener and more resilient supply chains, thus, supporting our nation’s goals and ambitions for a more sustainable future,” says Shadi Malak, CEO of Etihad Rail.

This initiative represents a significant step in Etihad Rail’s long-term commitment to environmental stewardship, directly contributing to its Environmental, Social, and Governance (ESG) strategy. Furthermore, it demonstrates Etihad Rail’s leadership in driving forward the UAE’s Net Zero by 2050 Strategy, supplemented by the railway network’s contribution to reducing CO2 emissions in the UAE road transport sector by 21% annually by 2050.

The Ghuweifat freight terminal serves as a key hub for facilitating seamless cross-border operations. With its strategic location at the border with Saudi Arabia, the terminal is uniquely positioned to accelerate sustainable logistics solutions regionally, aligning with Etihad Rail’s objectives to foster more eco-friendly freight operations.

By integrating solar technology into its network, Etihad Rail’s Ghuweifat terminal will eventually become self-sufficient, harnessing renewable energy to operate sustainably and reduce its carbon footprint, thus, setting a new standard for efficient and green logistics and infrastructure.

Two-faced Turkey imposes tariffs on solar panels from Asia

China opens a $1 billion agreement with Turkey to build EVs in Turkey
China makes a $1 billion deal with Turkey to build EVs in Turkey circumventing EU tariffs imposed on Chinese electric cars.

Turkey imposes tariffs on solar panels when it hurts its local economy but it speaks from the other side of its mouth when it stiffs Europe by helping China evade high tariffs on electric vehicles sold in Europe.

China evades tariffs through a $1B car factory it is building in Turkey. Meanwhile Volkswagen is seeing 3 factories shut down and 30,000 people laid off.

Keep Europe European

According to the Turkish General Directorate of Imports as of September 27, Energy Trend is reporting that Turkey has imposed a tariff of $25 per square meter on photovoltaic modules imported from Vietnam, Malaysia, Thailand, Croatia, and Jordan. But exemptions have been made for JinkoSolar’s Malaysian subsidiary, JA Solar’s Vietnamese subsidiary, Trina Solar’s Thai subsidiary, and Vina Solar, a Vietnamese module manufacturer acquired by Longi Green Energy a few years ago.

On November 25, 2023, Turkey’s Ministry of Trade announced that, at the request of Turkish companies, it had launched an anti-circumvention investigation into photovoltaic modules originating from China. The investigation seeks to determine whether Chinese products are being exported to Turkey via Vietnam, Malaysia, Thailand, Croatia, and Jordan to evade anti-dumping duties.

Turkey suspects that some companies from these five countries are using “transshipment” to circumvent the previously imposed $20 per square meter countervailing duty on Chinese photovoltaic products. After months of review, the Turkish government decided in March this year to impose a new tariff of $25 per square meter on photovoltaic products imported from these countries, a 25% increase over the previous tariff.

This is rich considering that Turkey is helping China circumvent EV trade tariffs as together China and Turkey build a $1B Chinese EV company, BYD, on its soil so that China and Turkey can both profit from EU electric vehicle tariff exemptions. Currently any China-made electric car would see a high tariff and tax if it gets sold in Europe – which does not make them a viable purchase in Europe. Meanwhile Volkswagen is laying off employees in Germany because of the lowered costs of cars coming from Asian countries like China.

Volkswagen is seeing 30,00 layoffs and the closure of three factories: “This is the plan of Germany’s largest industrial group to start the sell-off in its home country of Germany,” Cavallo added, not specifying which plants would be affected or how many of Volkswagen Group’s roughly 300,000 staff in Germany could be laid off.

Turkey is not part of the EU for a reason. It is playing dirty against Western values with Iran, Syria and China and its dealings with Chinese businesses to avoid EU tariffs should be investigated. Trump as the new US president will probably restructure this unholy alliance, but not before the quality of life in Europe crumbles further from globalism.

How bats navigate on sound alone over long distances

0

While we know that bats echolocate for short distances, for the first time science shows that bats can navigate in nature over many kilometers using only echolocation, without relying on other senses

Blind as a bat is an expression but now scientists show how bat navigation using sound really works when navigating long distances. Could this advance help propel autonomous vehicles or robotics in the future that look to biomimicry for inspiration?

“For the first time, we have shown that bats are able to navigate great distances in open areas with their eyes closed, using only echolocation; they even create a mental acoustic map of their surroundings,” say researchers from Tel Aviv University.

While we know that bats echolocate for short distances, for the first time science shows that bats can navigate in nature over many kilometers using only echolocation, without relying on other senses: “It’s well-known that bats are equipped with a natural sonar, allowing them to emit sound waves that bounce back from nearby objects, helping them navigate. However, it’s also known that bats use their sense of sight during flight.

Laboratory studies have shown that bats are able to navigate within enclosed spaces using only echolocation — but sonar ‘sees’ only about 10 meters ahead, so what happens under natural conditions, in open areas stretching over many kilometers? Can bats rely solely on echolocation for long-distance navigation?” 

Kuhl’s pipistrelle bat

The research was led by Prof. Yossi Yovel.

The innovative research, carried out over a six-year period, utilized a unique tracking system installed in Israel’s Hula Valley. Using this GPS-like technology, the researchers were able to track the flight of tiny bats from the species known as Kuhl’s pipistrelle, each weighing only six grams —— the smallest mammal ever to be monitored in this way.

For the study, the researchers collected around 60 bats from their roost in the Hula Valley area and moved them about three kilometers away from the roost — still within their familiar habitat. A tag was attached to each bat, and the eyes of some were covered with a cloth strip, temporarily preventing them from seeing during flight, though they could remove the covering with their feet upon landing.

In addition, the researchers employed techniques to temporarily disrupt the bats’ sense of smell and magnetic sense, thereby creating conditions in which they would be able to find their way home using only echolocation. Remarkably, the bats managed to return to their roost without difficulty.

In the second phase, the researchers built a computerized acoustic model of the bats’ natural environment in the Hula Valley.

Prof. Yovel explains: “This model is based on a 3D map of the area where the bats navigate, reflecting the echoes that the bat hears as it uses echolocation to journey through its surroundings. In examining the bats’ flight paths, we discovered that they choose routes where the echoes contain a lot of information, which helps them navigate. For example, an area rich in ​​vegetation, such as bushes and trees, returns echoes with more information than an open field, making bats less likely to fly over open terrain. We also found that some areas are characterized by distinct echoes, which are picked up by the bats.

“These findings strengthened our hypothesis that in any given area, bats know where they are based on the echoes. The bats effectively create an acoustic map in their head of their familiar environment, which includes a variety of active ‘sound landmarks’ (echoes) — just as every sighted person has a visual map of their everyday surroundings.”

In urban jungles and in medical settings it’s refreshing to see food gardens popping up as green roofs. Hospitals are to treat ailing folks, yet the food served to patients is usually over processed and of low quality.

Boston Medical Center (or BMC) is an academic medical center that delivers a model of healthcare where innovative and equitable care empowers all patients to thrive. In June this year Recover Green Roofs celebrated the opening of Newmarket Farm at Boston Medical Center and its 7300 square foot rooftop farm with wheelchair accessible green space.

With raised beds, a pollinator garden, plus an outdoor classroom, the design process highlights a critical collaboration between BMC, Recover Green Roofs, and Higher Ground Farm. Marking Recover’s second design and installation on BMC’s campus following the initial Boston Medical Center Power Plant Farm, both sites collectively forge new community partners and enhance access to fresh foods.

A portion of each harvest is donated to several South End nonprofits, including Rosie’s Place.

In 2022, Mayor Wu established GrowBoston to promote urban agriculture and food production, deploying funds from the American Rescue Plan Act. GrowBoston provided $300,000 to support the expansion of Newmarket Farm. The farm features a unique green roof media blend developed by Ben Flanner of Brooklyn Grange and Chuck Duprey at Naturcycle. They used a locally manufactured version of the innovative blend developed for the Javits Center Expansion Rooftop & Farm, optimized for deep growing crops, long term performance and water management. The growing media depth ranges from 19-23 inches and large growing beds with a granular drainage base retain tens of thousands of gallons of rainwater throughout the year, reducing the need for irrigation.

A high-tech custom drip irrigation system supplements regional rainfall.

Managed by Sarah Hastings, BMC’s Rooftop Farmer, and Higher Ground Farm, the farm adds valuable green space to the Newmarket District, addresses food insecurity, and offers culturally relevant fresh foods. Cultivating hard-to-find produce, they grow aji dulce, Malabar spinach, Callaloo greens, bok choy, napa cabbage, cranberry beans, and Japanese turnips, among others.

Because of Newmarket Farm’s location overlooking the Boston skyline, it also optimizes sun-loving fruit, including tomatoes, and flowers that attract pollinators. A covered seating area provides education and outreach classes to students from Boston Public Schools, members of local community organizations, and staff & patients to get hands-on training on hyperlocal vegetable gardening. Plus, both BMC rooftop farms serve as a model for other hospitals, understanding that the local environment is intrinsic to supporting the overall health and wellbeing in our communities.

Greenhouse agriculture in Kazakhstan

The eyes of Aishagul Duganova, a 48-year-old mother of three, light up as she talks about her new greenhouse, which is bringing with it a new stability amidst her family’s health problems and money troubles.

In the village of Koram, around 150 kilometers east of Almaty in Kazakhstan, Aishagul’s life has been marked by her husband’s debilitating injury and the severe illnesses of her elderly parents-in-law.
With her family completely reliant on her, Aishagul was caught between the demanding care they required and the necessity to earn money; yet she was unable to take advantage of work opportunities too far from home.
Before her husband’s accident, Aishagul worked with him in the field, and they sold their produce in local markets. But as his condition worsened, she could no longer leave him alone, pushing the family into a cycle of debt to cover medical expenses and sustain their children.
“Every day, I had to make a choice— care for my sick family or leave them behind to work. It was a choice no one should have to make,” Aishagul shares, her voice tinged with the fatigue of years of caregiving.
A turning point came when Aishagul’s sister-in-law, aware of her dire situation, introduced her to a greenhouse harvesting training programme. This initiative was part of the broader Food and Agriculture Organization of the United Nations (FAO) project, known as CACILM-2, and funded by the Global Environmental Facility (GEF).

Among its objectives, the project equips rural women in Kazakhstan with the skills and resources to adopt sustainable farming practices and make a living from agriculture. The training course provided by FAO’s partner, the Local Community Foundation of Enbekshikazakh District, Aishagul has improved her vegetables and produce-growing skills, allowing her to independently cultivate food.
Pavel Kavunov, an agronomist working at the Foundation, explained the training offered by the project: “We focused on practical, climate-smart agriculture techniques that ensure these women can produce quickly and sustainably.”
He imparted information on the characteristics of seedlings, their root systems and important aspects to consider during planting. “It’s about giving them the tools and the knowledge to succeed on their own terms,” he added.
This local expert presence ensures that the women farmers are not only trained but also have continual access to advice and problem-solving techniques, which is vital for the sustainability of their agricultural activities.
FAO also worked with Aishagul and nine other women to install 100 square metre, tunnel greenhouses on their lands. This collaboration has empowered them to cultivate vegetables all year-round in their backyards, opening the door to economic independence and lasting stability.
As the women learn to manage their micro-farms, they are supported by a network of agronomists and coordinators, such as Bakytgul Yelchibayeva, who assist them in connecting with local markets and buyers. “Our goal is to go beyond providing initial support by creating a lasting infrastructure that enables these women to thrive independently,” she explains.
Aishagul is now making the most of her new greenhouse, growing cucumbers and other vegetables to support her family. “This greenhouse has changed everything. It allows me to be with my family when they need me and still provide for them,” she explains. Encouraged by her success, Aishagul hopes to build a sustainable farm that also helps other women in her community learn and grow together.
In addition to the greenhouse, the project supported women farmers with tillage materials and cucumber seeds. Together, the women sold 3 992 kilograms of produce, earning roughly double what they would typically make. The boost in income from this extra produce helped improve the lives of 64 people, strengthening their community’s farming efforts.
 
The CACILM-2 project is providing targeted training, resources and coaching to rural communities in Central Asia, addressing several critical barriers such as inadequate job opportunities and lack of information. Moreover, through partnerships with local foundations and experts, participants forge connections with local markets and introduce their products to potential buyers, ensuring a reliable outlet for their produce.
By empowering rural women with the tools and knowledge to undertake agricultural ventures, FAO is promoting equality of opportunity, enhancing their economic stability and independence.

Slain Japanese doctor and canal builder Tetsu Nakamura gets his dream honored

Tetsu Nakamura, also known as Kaka Murad, was a Japanese physician and honorary Afghan citizen who headed Peace Japan Medical Services, an aid group known as Peshawar-kai in Japanese.

A Japanese doctor and humanitarian Tetsu Nakamura lived in Afghanistan for more than 3 decades leading humanitarian projects. His biggest dream was to realize a water canal project to give irrigation water to farmers in the Nangarhar province. His life was cut short in 2019 by a suspected group of armed Taliban militants believed to be sent from Pakistan. This year Nakamura’s dream came to life and 5 years after his death his largest project out of hundreds, a 20-mile canal, brings life-giving water to people who need it the most.

Born in Japan, Nakamura had been granted honorary citizenship in Afghanistan, reflecting the deep connections he forged with the country through his extensive humanitarian work. Apart from medical aid in the early years, he focused on constructing water canals, which were crucial for irrigation and agriculture in the arid region.

Following Nakamura’s passing, a non-governmental organization named PMS has taken up the cause to continue building canals and dams in the region.

Here is a beautiful film on his impact. Let’s not let terror win. Watch the movie, Water, Not Weapons below. And let us ponder: what is it that draws a man to leave his country and change the world in places that need help? Is there something inside of you that wishes to do the same?

Swedish silk turns clothes into charging stations with your body heat

Wear a dress from this silk and light up the room, literally

Imagine a sweater that powers electronics to monitor your health or charge your mobile phone while running. This development faces challenges because of the lack of materials that both conduct electricity stably and are well suited for textiles. Now a research group, led by Chalmers University of Technology in Sweden, presents an ordinary silk thread, coated with a conductive plastic material, that shows promising properties for turning textiles into electricity generators. Imagine a dress you are wearing that lights up the night – literally!

Textile materials with piezoelectric properties can be obtained in the form of yarns and filaments, woven fabric structures, knitted fabric
Textile materials with piezoelectric or thermoelectric properties can be obtained in the form of yarns and filaments, woven fabric structures, knitted fabrics.

Thermoelectric textiles convert temperature differences, for example between our bodies and the surrounding air, into an electrical potential. This technology can be of great benefit in our everyday lives and in society. Connected to a sensor, the textiles can power these devices without the need for batteries. These sensors can be used to monitor our movements or measure our heartbeat.


Since the textiles must be worn close to the body, the materials used in them must meet high demands on safety and flexibility. The silk thread that the researchers tested has a coating made of a conducting polymer. It is a plastic material with a chemical structure that makes the material electrically conductive and well adapted to textiles.

“The polymers that we use are bendable, lightweight and are easy to use in both liquid and solid form. They are also non-toxic,” says Mariavittoria Craighero, who is a doctoral student at the Department of Chemistry and Chemical Engineering at Chalmers University of Technology, and first author of a recently published study.

Enhanced stability and conductivity

The method used to make the electrically conductive thread is the same as used in previous studies within the same research project.  Previously, the thread contained metals to maintain its stability in contact with air. Since then, advances have been made to manufacture the thread with only organic (carbon-based) polymers. In the current study, the researchers have developed a new type of thread with enhanced electrical conductivity and stability.

“We found the missing piece of the puzzle to make an optimal thread – a type of polymer that had recently been discovered. It has outstanding performance stability in contact with air, while at the same time having a very good ability to conduct electricity. By using polymers, we don’t need any rare earth metals, which are common in electronics,” says Mariavittoria Craighero.

To show how the new thread can be used in practice, the researchers manufactured two thermoelectric generators – a button sewn with the thread, and a piece of textile with sewn-in threads. When they placed the thermoelectric textiles between a hot and a cold surface, they could observe how the voltage increased on the measuring instrument.

The effect depended on the temperature difference and the amount of conductive material in the textile.  As an example, the larger piece of fabric showed about 6 millivolts at a temperature difference of 30 degrees Celsius. In combination with a voltage converter, it could theoretically be used to charge portable electronics via a USB connector.  The researchers have also been able to show that the thread’s performance is maintained for at least a year. It is also machine washable.

“After seven washes, the thread retained two-thirds of its conducting properties. This is a very good result, although it needs to be improved significantly before it becomes commercially interesting,” says Mariavittoria Craighero.

Can meet functions that these textiles require

The thermoelectric fabric and button cannot be produced efficiently outside the lab environment today. The material must be made and sewn in by hand, which is time-consuming. Just sewing it into the demonstrated fabric required four days of needlework. But the researchers see that the new thread has great potential and that it would be possible to develop an automated process and scale up.

“We have now shown that it is possible to produce conductive organic materials that can meet the functions and properties that these textiles require. This is an important step forward. There are fantastic opportunities in thermoelectric textiles and this research can be of great benefit to society,” says Christian Müller, Professor at the Department of Chemistry and Chemical Engineering at Chalmers University of Technology and research leader of the study.

Blood sugar control keeps your brain young: Eat the Med Diet!

Mediterranean Diet, this is a salad

The Green Mediterranean Diet Shows Promise in Keeping Brains Young

Age-related brain atrophy, the gradual loss of neurons and shrinkage of brain tissue, is a natural part of aging, which can lead to cognitive decline and other neurological issues. While so far aging cannot be prevented, recent research from an 18-month dietary intervention offers hope that lifestyle and dietary changes can slow brain aging. A new international study, led by Ben-Gurion University, as part of the DIRECT PLUS Brain MRI trial, has brought to light how blood sugar control can significantly impact brain health.

Brain age, as evaluated by MRI measurements of the hippocampus and lateral ventricles, reflects the biological aging of the brain, which can differ from a person’s chronological age. Chronological age is the number of years lived, while brain age indicates the brain’s actual health. Typically, as we age, the hippocampus shrinks and the lateral ventricles expand, serving as markers of brain aging. Some individuals have a brain age younger or older than their chronological age. A younger brain age suggests better cognitive health, while an older brain age may indicate accelerated aging and increased risk of cognitive decline.

The study, which was published recently in The American Journal of Clinical Nutrition, was conducted by an international team of brain and nutrition experts, including researchers from Ben-Gurion University, Harvard University, Leipzig University, and more. The research was primarily carried out by Ph.D. student Dafna Pachter and overseen by Prof. Iris Shai, along with several international collaborators.

A previous study published two years ago American Journal of Clinical Nutrition, reported that Mediterranean (MED) and green-MED diets significantly attenuated age-related brain atrophy by ∼50% within 18 months.

In the current study, the researchers aimed to understand the mechanism by which the slowing of brain atrophy occurs.

The study found that a decline in HbA1c, and key markers of long-term blood sugar levels, are associated with significant positive changes in specific brain regions commonly affected by age-related atrophy. Brain MRI results showed that lower HbA1c levels corresponded to greater deviations in the thalamus, caudate nucleus, and cerebellum – areas crucial for cognitive function, motor control, and sensory processing. The study suggests that improved blood sugar control could be one of the most important factors in slowing down age-related brain changes.

Earlier research has highlighted the benefits of the Green Mediterranean (Green-Med) diet, including better blood sugar control. The Green-Med diet is rich in polyphenols from plant-based sources like Mankai (a high-protein aquatic plant) and green tea, while being low in red and processed meats. The current study further strengthens this connection by suggesting that the Green-Med diet may not only support metabolic health but also exert protective effects on brain structure and function.

One of the Largest Brain MRI intervention Studies in the World

The DIRECT PLUS trial, one of the longest and largest brain MRI studies conducted to date, involved approximately 300 participants who were divided into three dietary groups. Whole-brain MRI measurements were taken before and after the 18-month trial to track changes in brain health. The researchers used Hippocampal Occupancy (HOC), as a proxy for brain age which predicts future risk of dementia. HOC typically decreases with age. Interestingly, some participants exhibited a brain age either younger or older than their chronological age.

Using NeuroQuant, an FDA-authorized fully automated tool, the research team quantified and segmented the brain MRI-derived data. The study aimed to examine whether improved glycemic control and specific dietary components could slow down brain aging. The results indicated that participants who managed to improve their blood sugar levels and achieve normal glucose status experienced a more pronounced attenuation of brain aging. Notably, those who consumed higher amounts of green tea and Mankai duckweed shakes demonstrated the most significant improvements in both blood sugar levels and brain health.

Glycemic Control and Polyphenols: The Key to a Younger Brain Age?

The study’s lead researcher, Prof. Iris Shai, from Ben-Gurion University, an adjunct professor at Harvard University, and an Honorary Professor at Leipzig University, explains, “Maintaining low blood sugar levels, even within the normal range, shows promise for preserving a younger brain, especially when combined with a healthy diet and regular physical activity. Specifically, polyphenols found in plant-based foods may cross the blood-brain barrier and help reduce brain inflammation, which is crucial for memory”.

Dafna Pachter, a Ph.D. student and the first author of the paper, adds, “This trial offers a safe approach to potentially slow down our brain aging—by adopting the components of a green-Mediterranean diet.”

A Pathway to Reducing Age-Related Cognitive Decline

This study is one of the first large-scale trials to directly link dietary changes, particularly those associated with the Green-Med diet, to improved glycemic control and slower brain aging. While further research is needed to fully understand the mechanisms at play, these results suggest a potential avenue for reducing the risk of age-related cognitive decline through relatively simple dietary adjustments.

The DIRECT PLUS trial was funded by grants from the German Research Foundation (DFG), Israel Ministry of Health, Israel Ministry of Science and Technology, and the California Walnuts Commission. None of the funding providers were involved in any stage of the design, conduct, or analysis of the study, nor did they have access to the study results before publication.

What is the Mediterranean Diet?

The best diet starts with a healthy plate of food. Experts the world over suggest the Mediterrean Diet for heart health

The Mediterranean diet isn’t a strict diet plan but rather a way of eating based on the dietary traditions of Crete, Greece, and Southern Italy during the mid-20th century. This area now includes food from Lebanon and Israel. A diet rich in fruits, vegetables, beans, nuts, whole grains, fish, olive oil, small amounts of dairy, and red wine offered extensive health benefits.

One quarter Israel’s cars are electric but green taxation isn’t working

Tesla in Israel

Researchers say that the money invested in green taxation in Israel does not achieve its public goals. Instead of reducing pollution, greenhouse gas emissions, and encouraging electric vehicles, it has become a strategic pricing tool used by car importers to influence their profits.

A study indicates that the green tax reform implemented in Israel for 15 years with the aim of reducing air pollution and greenhouse gas emissions has not achieved its goals. Based on the findings of the study Ben-Gurion University of the Negev published a surprising recommendation: to abolish all tax brackets for polluting vehicles and leave only one broad tax benefit for the purchase of electric vehicles.

In Israel, unlike the rest of the world, the green tax system on new vehicle purchases determines benefits in tax rates based on emission level. Thus, vehicles with low pollution ratings receive a benefit of up to 16,530 shekels, while vehicles with high pollution ratings receive no benefit at all. In 2023, there was a significant increase in the purchase of electric vehicles in Israel, from 45,270 in 2022 to 95,761, accounting for 27.4% of all new vehicles. This is a significant increase compared to previous years and reflects a clear trend of changing public preferences.

Fifteen years after the green tax reform, a research group led by Prof. Ofir Rubin and Prof. Stav Rosenzweig from the Guilford Glazer Faculty of Business and Management and the Goldman Sonnenfeldt School of Climate Change at Ben-Gurion University of the Negev examined its impact and found that from 2016 onwards, the impact of the green tax was offset and became virtually meaningless. It appears that drivers who purchased efficient cars gradually increased their mileage, creating a “rebound effect” that grew until it completely nullified the impact of the tax.

Between 2016 and 2023, the state granted benefits totaling over NIS 34.5 billion, but did not create the desired savings in energy or pollution levels.

Transportation is one of the human activities with the most severe impact on the environment and climate. The main reason for pollution and emissions from transportation stems from the fact that modern transportation relies heavily on fossil fuels, which exacerbates the effects on global warming and environmental damage. Additionally, the global economic damage from air pollution is estimated at hundreds of billions of dollars per year. Economic losses include medical treatment costs for diseases such as asthma, loss of workdays, and decreased productivity.

The researchers say that the money invested in green taxation in Israel does not achieve its public goals. Instead of reducing pollution, greenhouse gas emissions, and encouraging electric vehicles, it has become a strategic pricing tool used by car importers to influence their profits.

The lack of government oversight over vehicle pricing has allowed importers to generate high profits from tax benefits without fully passing them on to consumers. Therefore, the consumer response to tax benefits was minimal and did not generate a meaningful change in purchasing habits, which is one of the reasons why there was only a partial impact on the environment.

The National Institute for Climate and Environmental Policy Research recommends a simpler and more focused policy, which will include, on the one hand, the abolition of purchase tax benefits for polluting vehicles and, on the other hand, the imposition of a distance-based road tax, where the price will be calculated according to distance and travel time, with higher rates during peak hours. Such a tax can help reduce traffic congestion and reduce emissions.

“These measures offer a practical and focused tax system that will directly impact the reduction of air pollution and encourage the transition to electric vehicles, while maintaining simplicity and flexibility in the tax system, without the need for oversight of the pricing strategy of car importers,” explained Tamar Zandberg from Ben-Gurion University of the Negev. She is the former Minister of Environmental Protection. “These recommendations are designed to encourage the transition to clean energy and reduce air pollution and greenhouse gas emissions more effectively,” she concluded.

The Fight for Water in Yemen’s Drying Land

0

In the arid landscape of Yemen’s West Coast, water is often a distant dream. For many years, families have endured long walks under the scorching sun in search of clean water. “We walk for hours, just for a few jerrycans of water,” shares Hassan, a father of four who arrived in Yakhtol five years ago. “Some days, we come back empty-handed. It feels like the water is slipping further out of reach.”

The war in Yemen (see how the Houthis use water as a weapon in war) has forced over 4.5 million people from their homes, and many have sought refuge in rural villages like Yakhtol. As more displaced families arrive, often with nothing more than the clothes on their backs, the strain on already scarce resources grows. The expanding population is now forced to compete for access to water, shelter, and basic services, further exacerbating the challenges faced by both displaced individuals and local residents.

The declining soil fertility, increasing salinization of water sources, and rising sea levels have severely threatened agriculture along Yemen’s coast, particularly in Yakhtol. A once-modest fishing and farming community now has to battle for its very survival.

Yakhtol’s residents, who once relied on small-scale agriculture to sustain their families, now find it nearly impossible to grow crops or feed their livestock. The climate has become increasingly hostile to traditional farming methods. Small-scale fishing, which had also been a lifeline for the local economy, is in decline. As crops fail and fish stocks dwindle, the population is left with fewer options.

Mohammed Ali, another resident of Yakhtol, knows this all too well. “If there is no water, we cannot live – water is life,” he says. Each day, he wakes before dawn to search for water, a task that consumes his mornings and drains his energy. His daily trips to communal water points are fraught with uncertainty. “How long will I have to wait? Will I find enough water to support my family? Will I find any at all?” he asks.

This struggle for water is compounded by years of conflict that have ravaged the infrastructure once vital to Yakhtol’s survival. The water system, originally built to serve 200 homes, is now stretched beyond its limits, trying to meet the needs of over 1,500 families, including hundreds of displaced people who have sought refuge from violence in frontline areas.

To address these challenges, the United Nation’s-run International Organization for Migration (IOM) has stepped in to restore the water infrastructure. Through the rehabilitation of pipelines and the construction of new water points, IOM’s intervention helps alleviate the burden on families like Hassan’s and mitigate conflict over resources. The project also addresses health risks by ensuring that both host communities and displaced families have reliable access to clean water.

As part of its efforts in Yakhtol, IOM has also worked on expanding the water-distribution network. This includes installing larger pipes and constructing additional water-storage facilities, ensuring that the limited supply is efficiently distributed across the community. Solar-powered water-pumping systems have been introduced, providing a sustainable energy source that reduces reliance on expensive and often unavailable fuel.

Furthermore, IOM is working to help communities better withstand extreme weather events like floods. This involves upgrading the water system to improve its flood resilience, carefully planning to avoid areas that are prone to flooding and creating protective measures such as gabion walls. Additionally, automatic chlorinators will be installed to disinfect water.

The expansion of water infrastructure in Yakhtol brings hope to families like Mohammed’s, who have endured years of hardship. “I used to take water for granted,” Mohammed recalls. “Now, even a single drop feels like a precious gift.”

While progress has been made in Yakhtol, similar struggles continue in other parts of the West Coast. In a displacement camp in Hays, Sami, a father of twelve, shares a familiar story of hardship. “Most of the people who go to fetch water here are children; they don’t go to school because they have to help,” he explains. The lack of access to clean water has deprived his children of education, forcing them into a cycle of daily household chores.

In Hays, IOM is working to address the severe water shortage by constructing a new well that will provide clean and reliable water to thousands of displaced families and host communities. This well is a critical lifeline in a community where the daily search for water has long consumed families’ time and energy. By providing a consistent water source, IOM’s intervention not only eases the physical burden on families but also reduces health risks linked to contaminated water.

Despite these efforts, the challenges remain daunting. Climate change and extreme weather events across Yemen continue to amplify the country’s water crisis, adding to the pressures of conflict and displacement. Despite the daunting challenges, Sami remains optimistic: “We support each other through the hardships,” he says.

As communities continue to grapple with these overlapping crises, the work of organizations like IOM offers a glimmer of hope. Through the rehabilitation of water systems and the provision of essential aid, IOM is helping to restore dignity and stability to families pushed to the brink by conflict and climate change.

Families like Sami’s and Hassan’s understand that while clean water is essential, it is only part of what is needed to rebuild their lives. “We need more than just water,” Hassan says. “We need our children to be able to go to school. We need to feel safe.”

Lasers detect ancient Mayan city hidden in the jungle

ancient Mayan city

An ancient Maya city has been found hidden in plain sight”beneath the jungle in the Mexican state of Campeche. Archaeologists used a laser technique called LiDAR to scan the area, “accidentally” discovering the forgotten complex, which contains pyramids, amphitheatres and sports fields.

“The government never knew about it, the scientific community never knew about it. That really puts an exclamation point behind the statement that no, we have not found everything, and yes, there’s a lot more to be discovered,” said researcher Luke Auld-Thomas working on the site.

The new research, published in the journal Antiquity, was led by Tulane University anthropology doctoral student Auld-Thomas and his advisor, Professor Marcello A. Canuto.

They think the site, which they’ve named Valeriana, might have housed up to 50,000 people, which supports claims that Maya lived in complex cities or towns, not in isolated villages.

The team used lidar, a laser-based detection system, to survey 50 square miles of land in Campeche, Mexico, an area largely overlooked by archaeologists. Their findings included evidence of more than 6,500 pre-Hispanic structures, including a previously unknown large city complete with iconic stone pyramids.

“Our analysis not only revealed a picture of a region that was dense with settlements, but it also revealed a lot of variability,” said Auld-Thomas: “We didn’t just find rural areas and smaller settlements. We also found a large city with pyramids right next to the area’s only highway, near a town where people have been actively farming among the ruins for years.

The Middle American Research Institute (MARI) at Tulane University has been pioneering the use of lidar technology in archaeological research. Over the past decade, MARI has built a state-of-the-art Geographic Information Systems (GIS) lab, to analyze remote sensing data, such as lidar. The lab is managed by Francisco Estrada-Belli, a research professor in Tulane’s Department of Anthropology.

Just think about what waits to be discovered in the Holy Land and in countries like Saudi Arabia- just opening up to archeologists for discovery.

Lidar technology uses laser pulses to measure distances and create three-dimensional models of specific areas. It has allowed scientists to scan large swaths of land from the comfort of a computer lab, uncovering anomalies in the landscape that often prove to be pyramids, family houses and other examples of Maya infrastructure.

This research may also help resolve ongoing debates about the true extent of Maya settlements.

“Because lidar allows us to map large areas very quickly, and at really high precision and levels of detail, that made us react, ‘Oh wow, there are so many buildings out there we didn’t know about, the population must have been huge,’” Auld-Thomas said. “The counterargument was that lidar surveys were still too tethered to known, large sites, such as Tikal, and therefore had developed a distorted image of the Maya lowlands.

“What if the rest of the Maya area was far more rural and what we had mapped so far was the exception instead of the rule?”

The study highlights the transformative power of lidar technology in unveiling the secrets of ancient civilizations. It also provides compelling evidence of a more complex and varied Maya landscape than previously thought.

“Lidar is teaching us that, like many other ancient civilizations, the lowland Maya built a diverse tapestry of towns and communities over their tropical landscape,” Canuto said. “While some areas are replete with vast agricultural patches and dense populations, others have only small communities. Nonetheless, we can now see how much the ancient Maya changed their environment to support a long-lived complex society.”

America’s space agency NASA has identified nine potential landing regions for its upcoming Artemis III mission, the first crewed Moon landing since 1972.

The regions are all near the lunar South Pole, an area of the Moon that has never been explored. Selection criteria included terrain suitability, lighting conditions and communication capabilities with Earth.

“The Moon’s South Pole is a completely different environment than where we landed during the Apollo missions,” says Sarah Noble, Artemis lunar science lead. “It offers access to some of the Moon’s oldest terrain, as well as cold, shadowed regions that may contain water and other compounds.”

These regions contain diverse geological characteristics and offer flexibility for mission availability. The lunar South Pole has never been explored by a crewed mission and contains permanently shadowed areas that can preserve resources, including water.

The refined candidate Artemis III lunar landing regions are, in no priority order:

  • Peak near Cabeus B
  • Haworth
  • Malapert Massif
  • Mons Mouton Plateau
  • Mons Mouton
  • Nobile Rim 1
  • Nobile Rim 2
  • de Gerlache Rim 2
  • Slater Plain

To select these landing regions, a multidisciplinary team of scientists and engineers analyzed the lunar South Pole region using data from NASA’s Lunar Reconnaissance Orbiter and a vast body of lunar science research.

Factors in the selection process included science potential, launch window availability, terrain suitability, communication capabilities with Earth, and lighting conditions. Additionally, the team assessed the combined trajectory capabilities of NASA’s SLS (Space Launch System) rocket, the Orion spacecraft, and Starship HLS (Human Landing System) to ensure safe and accessible landing sites.

“Artemis III will be the first time that astronauts will land in the south polar region of the Moon. They will be flying on a new lander into a terrain that is unique from our past Apollo experience,” said Jacob Bleacher, NASA’s chief exploration scientist. “Finding the right locations for this historic moment begins with identifying safe places for this first landing, and then trying to match that with opportunities for science from this new place on the Moon.”

NASA’s site assessment team will engage the lunar science community through conferences and workshops to gather data, build geologic maps, and assess the regional geology of eventual landing sites. The team also will continue surveying the entire lunar South Pole region for science value and mission availability for future Artemis missions. This will include planning for expanded science opportunities during Artemis IV, and suitability for the LTV (Lunar Terrain Vehicle) as part of Artemis V.
