The Arabian Gulf and the Red Sea are major sources of seafood and vital reservoirs of two of the most precious resources: water and oil.

The rich marine ecosystems within these bodies of water are characterized by a diverse array of unique and indigenous plants and animals that play crucial roles in maintaining ecological balance.

However, these sensitive habitats may experience significant physical and chemical stresses if the natural equilibrium is disturbed. 

Saudi Arabia is taking a leadership role on the global stage with its innovative and patented technologies developed by the Saudi Water Authority’s Water Technology Innovation and Research Development Institute.

These initiatives are focused not only on efficient desalination, but also on the responsible management of brine as a resource rather than merely as a waste product.

WTIIRA-SWA has created a groundbreaking dual brine concentration design that combines a nanofiltration system upstream of a reverse osmosis system and a membrane brine concentration system downstream.

This technology enables the extraction of two valuable brine streams: one that consists of concentrated and purified monovalent ions, which can be used to produce high-purity sodium chloride and bromine, and another that is rich in divalent ions usable for manufacturing various calcium and magnesium salts.

Such innovation not only contributes to the sustainability of desalination processes but also opens new avenues for economic viability, connecting the desalination industry to a range of applications in sectors such as chlor-alkali production, pharmaceuticals and cosmetics.

These initiatives are focused not only on efficient desalination, but also on the responsible management of brine as a resource rather than merely as a waste product.

Another noteworthy achievement in this field is the extraction of vaterite calcium carbonate, distinguished by its unique chemical properties, including high porosity, increased surface area, greater solubility and biodegradability.

These attributes make vaterite calcium carbonate especially suitable for controlled release in pharmaceutical formulations, serving as an effective carrier for drug delivery. By harnessing such advanced materials, WTIIRA-SWA underscores its commitment to innovation in resource recovery.

Moreover, WTIIRA-SWA has implemented several pioneering strategies to minimize the environmental impact of desalination brine and preserve the precious ecosystems surrounding the Kingdom.

Efficient technology implementation: Modern desalination plants in Saudi Arabia utilize advanced technologies that emphasize energy efficiency and environmental sustainability. 

Brine disposal management: In Saudi Arabia, the strategies for brine disposal are carefully considered. Detailed studies of dilution factors, dispersion patterns, and the assimilative capacity of the receiving marine environment are conducted to ensure that discharged brine is safely integrated without detrimental effects on marine life.

Monitoring and regulation: Rigorous environmental monitoring programs are established to assess the impact of desalination plant effluents on the marine ecosystem. 

Coastal ecosystem preservation: Strategic placement of desalination plants is intended to reduce impacts on sensitive coastal ecosystems. 

Research and development: Ongoing research and development initiatives aim to improve desalination technologies and processes further. 

Through these comprehensive approaches, WTIIRA-SWA is not only addressing the challenges of desalination but also setting a global standard for sustainability in the management of water resources.

  • the Qatar Investment Authority will be “a long-term investor and partner” in the Audi F1 team

LUSAIL, Qatar: The sovereign wealth fund of Qatar is acquiring a “significant minority stake” in what will become Audi’s works Formula 1 team from 2026, in a deal announced Friday at the Qatar Grand Prix.
A joint statement said the Qatar Investment Authority will be “a long-term investor and partner” and provide “a substantial capital injection” that will help the team expand its infrastructure.
The team is currently competing as Sauber and will be rebranded as the Audi works outfit for 2026 after it reached agreement for a full takeover earlier this year.
“This additional capital will accelerate the team’s growth and is yet another milestone on our long-term strategy,” Audi chief executive Gernot Döllner said in the joint statement.
Qatar is already an investor in the Volkswagen Group, of which Audi is a part.
“QIA believes that Formula 1 is a sport with significant untapped investment potential,” QIA chief executive Mohammed Saif Al-Sowaidi said.
“The increasing commercialization of professional sports as an entertainment offering globally, and the increasingly global popularity of Formula 1, has made for an exciting opportunity for our first major motorsports investment.”
Sauber is changing both of its drivers for 2025, when Nico Hülkenberg and rookie Gabriel Bortoleto arrive to replace Valtteri Bottas and Zhou Guanyu.
It is the only team yet to score a point this season. Bottas placed 13th and Zhou 19th in Friday’s qualifying for the Saturday sprint race, which was the first competitive session since the agreement was announced.

  • Vision Friend uses cameras, sensors, and alarms
  • Design beat nearly 1,000 entries from 19 countries

JEDDAH: An eight-year-old inventor from Saudi Arabia won an international competition for designing a pair of glasses that aim to help blind people navigate the world safely.

Lama Al-Badin, from Dammam, won an $800 cash prize for her Vision Friend design after beating nearly 1,000 entries from 19 countries in the “Glasses of the Future” competition.

Organized by the International Agency for the Prevention of Blindness, the competition challenged children worldwide to reimagine eyewear to support eye health and accessibility.

HIGHLIGHTS

• Organized by the International Agency for the Prevention of Blindness, the competition challenged children worldwide to reimagine eyewear to support eye health and accessibility.

• Despite her young age, Lama Al-Badin demonstrated resourcefulness throughout the competition. She acknowledged the challenges she faced during the design phase.

Al-Badin’a design impressed the jury with its cameras and sensors that would detect obstacles and alert blind and visually-impaired users of dangers through various alarm sounds and vibrations.

“I always have scientific discussions with my family at home, which often spark various ideas that serve life in meaningful ways,” Al-Badin told Arab News.

“When I learned about the competition through a school announcement, the idea for the glasses emerged. I envisioned them as a companion to help people face road dangers through sensor systems. I wanted to add warning tones to enhance their auditory sensitivity and active awareness.”

Her design incorporates eco-friendly materials such as bamboo and recycled plastic, and includes cutting-edge features like sensors, an alarm system, and a multi-functional charging case.

Despite her young age, Al-Badin demonstrated resourcefulness throughout the competition. She acknowledged the challenges she faced during the design phase and said, “embarking on a new experience was an exciting challenge for me.

“During the design phase, the main challenge was translating my idea and vision from paper into a digital design. At that point, I sought help from my older sister because I hadn’t yet learned this type of drawing.”

Winning the competition has brought immense pride to her family and the country. She said: “I feel happy and proud. Winning is a motivation for me to develop further and achieve more accomplishments.

“I feel proud and hope to be an active member in the development and building of my beloved country.”

Her family, too, played a pivotal role in her journey. “They were very happy with this wonderful achievement. My family is my primary supporter, and I thank them.

“They have been my source of inspiration and encouragement. Praise be to God, I live in an aware family. At home, we love exchanging information and brainstorming solutions to all kinds of problems.”

Al-Badin’s design resonated with Caroline Casey, president of the IAPB and a member of the competition jury.

“The thing that stood out the most was how conscious and aware Lama was about her role in protecting the planet that she lives on and her ability to see how technology can be an enabler,” she told Arab News.

“In her mind, there were no barriers in the way of creating a product that was friendly to the planet and friendly to humans. When you consider her glasses, you’d think, ‘Yeah, why aren’t I doing it?’”

She continued: “A young person’s imagination doesn’t seem to focus on what we can’t achieve but on what is possible. I just love her approach and can’t wait to wear a pair.”

Casey also underscored the broader impact of initiatives like the “Glasses of the Future” competition. She said: “I want every child to be able to ‘see their future,’ both literally and metaphorically. Ensuring that every single child on this planet has access to affordable, accessible eyecare and health determines the future potential of our global citizenship and planet.”

Alongside Al-Badin, five-year-old Grace Rita from Kenya won the Younger Kids category for her vibrant and imaginative glasses, A Friend for My Eyes.

Rita’s design focuses on making eyewear fun and approachable for children with features like glow-in-the-dark frames and customizable lenses.

Besides Casey, the competition’s judging panel was composed of a global jury of experts, including Jo Frost, parenting expert and TV personality, and Dr. Prabha Choksi, ophthalmologist and founder of the Dr. Choksi Vitiligo Foundation.

Frost told Arab News: “I was truly impressed by the creativity and innovation of these little geniuses, each design brought a big smile of joy. We can all agree that eye health is often overlooked in our busy day-to-day lives of raising children, despite its importance to a child’s development and future.

“However, with Lama’s design’s inclusiveness, scientific aspects, and Grace’s bright and inspiring colors, these designs not only demonstrate the need to engage children in the global conversation about eye health but also empower eyewear wearers around the world.”

The competition also comes on the heels of critical research by the IAPB, which revealed that children with low vision learn only half as much as their peers with good or corrected vision in school.

This study, released in collaboration with the Seva Foundation on World Sight Day, underscores the profound impact of early interventions like eye exams and prescription glasses.

  • Intense Israeli airstrikes over the past two months leveled entire neighborhoods in eastern and southern Lebanon, as well as the southern suburbs of Beirut, which are predominantly Shiite areas of Lebanon where Hezbollah has a strong base of support

BAALBEK, Lebanon: In eastern Lebanon’s city of Baalbek, the Jawhari family gathered around a gaping crater where their home once stood, tears streaming as they tried to make sense of the destruction.
“It is heart-breaking. A heartache that there is no way we will ever recover from,” said Lina Jawhari, her voice breaking as she hugged relatives who came to support the family.
“Our world turned upside down in a second.”
The home, which was a gathering place for generations, was reduced to rubble by an Israeli airstrike on Nov. 1, leaving behind shattered memories and twisted fragments of a once-vibrant life.
The family, like thousands of Lebanese, were returning to check on their properties after the US-mediated ceasefire between Israel and Hezbollah went into effect early Wednesday.

BACKGROUND

Israeli airstrikes have left a massive trail of destruction across Lebanon.

Intense Israeli airstrikes over the past two months leveled entire neighborhoods in eastern and southern Lebanon, as well as the southern suburbs of Beirut.
Nearly 1.2 million people have been displaced.
The airstrikes have left a massive trail of destruction across the country.
A photo of the Jawhari family’s home — taken on a phone by Louay Mustafa, Lina’s nephew — is a visual reminder of what had been. As the family sifted through the rubble, each fragment recovered called them to gather around it.
A worn letter sparked a collective cheer, while a photo of their late father triggered sobs. Reda Jawhari had built the house for his family and was a craftsman who left behind a legacy of metalwork. The sisters cried and hoped to find a piece of the mosque-church structure built by their father. Minutes later, they lifted a mangled piece of metal from the debris. They clung to it, determined to preserve a piece of his legacy.
“Different generations were raised with love ... Our life was filled with music, dance, and dabke (traditional dance). This is what the house is made up of. And suddenly, they destroyed our world. Our world turned upside down in a second. It is inconceivable. It is inconceivable,” Lina said.
Despite their determination, the pain of losing their home and the memories tied to it remains raw.
Rouba Jawhari, one of four sisters, had one regret.
“We are sad we did not take my mom and dad’s photos with us. If only we took the photos,” she said, clutching an ID card and a bag of photos and letters recovered from the rubble.
“It didn’t cross our mind. We thought it was two weeks and we will be back.”
The airstrike that obliterated the Jawhari home came without warning, striking at 1:30 p.m. on what was otherwise an ordinary Friday.
Their neighbor, Ali Wehbe, also lost his home. He had stepped out for food a few minutes before the missile hit and rushed back to find his brother searching for him under the rubble.
“Every brick holds a memory,” he said, gesturing to his library.
“Under every book you would find a story.”

  • The 6 Hours of Jeddah race marks the final race of the GTWC season with Mercedes, Porsche and Ferrari battling it out for the title

JEDDAH: Mercedes-AMG Team GetSpeed topped Friday’s Free Practice in the GT World Challenge finale at the Jeddah Corniche Circuit, with Jules Gounon leading the way in a two-hour session that began in daylight and ended with the sun setting over the Red Sea. 

The 6 Hours of Jeddah race marks the final race of the GTWC season with Mercedes, Porsche and Ferrari battling it out for the title.

Gounon was the first driver to break the two-minute barrier, posting a 1m 59.839s at the halfway mark. He subsequently shaved a further three hundredths of this to end Free Practice with a 1m 59.804s. 

Matteo Cairoli came within touching distance of Gounon’s benchmark with a 1m 59.894s during the final 30 minutes. In doing so, the Iron Lynx Lamborghini jumped ahead of Maro Engel, whose time of 2m 00.093s demonstrated that the Mercedes Team Mann-Filter entry is fully up to speed following its testing accident on Thursday.

Gold Cup title favorite Sainteloc Racing placed fourth overall with Gilles Magnus at the wheel of the Audi. The Rutronik Racing Porsche continued the strong pace it demonstrated on Thursday by placing fifth overall and leading the Bronze Cup thanks to Loek Hartog.

The Boutsen VDS Mercedes-AMG was sixth, followed by the title-chasing AF Corse Francorchamps Motors Ferrari.

Sainteloc Racing also paced the Silver Cup with its #26 Audi. Kobe Pauwels posted a 2m 00.494s to place 19th overall. A total of 47 cars were on-track during Free Practice following the withdrawal of the Walkenhorst Motorsport Aston Martin, which crashed during Thursday’s Bronze Test. 

In contrast with Thursday’s sessions, Free Practice brought almost no on-track incidents. A number of cars brushed the wall as they tested the limits of the high-speed Jeddah circuit, but there were no stoppages during the two-hour run.

However, there was more bad news for the Walkenhorst squad, which suffered a serious fire in one of its Aston Martins. No one was harmed in the incident, though the car’s continued participation in the event is unclear.
