At night on Mansouri beach, the first evidence was often a track in the sand. The beach lies south of Tyre, near the border with Israel, where checkpoints, shelling, and evacuation orders have long shaped daily life. It is also one of Lebanon’s important nesting grounds for loggerhead and green sea turtles. The turtles come ashore after dark. They dig, lay, cover, and return to the water. For the hatchlings, the distance from nest to sea is only a few yards. It is still dangerous. Dogs and foxes dig up eggs. Crabs and birds take the young. Lights from roads and resorts pull them away from the water. Plastic drifts offshore. Fishing nets catch adults that have survived for decades. Even a footprint can trap a turtle no bigger than a child’s palm. Mona Khalil gave much of her life to that narrow strip of beach. She was 76 when she died on June 19 from wounds sustained after an Israeli airstrike struck her home at Mansouri beach earlier that month. Her assistant was also injured, suffering severe burns. The house, known to visitors and volunteers as the Orange House, had been the base of her conservation work for more than 25 years. Mona Khalil in 2004 in Lebanon.

Dassault Aviation has achieved a major milestone in its business jet program as the all-new Falcon 10X successfully completed its maiden flight. The step marks the beginning of the aircraft’s flight-test campaign and demonstrating the maturity of the development program.
The inaugural flight took place from Bordeaux-Mérignac Airport in France, where test pilot Sébastien Dupont de Dinechin and copilot Fabrice Dougnac lifted off aboard the Falcon 10X for a mission lasting approximately two and a half hours.
During the flight, the crew evaluated the aircraft’s handling characteristics and onboard systems, reaching an altitude of 40,000 feet and accelerating to Mach 0.82 before returning for a smooth landing.
First flight
The successful first flight represents a significant step forward for Dassault Aviation as it prepares what is expected to become one of the most advanced and spacious ultra-long-range business jets in the world.
Speaking on the achievement, Dassault Aviation Chairman and CEO Eric Trappier described the maiden flight as an important milestone for the company. He credited the accomplishment to the dedication and expertise of the engineering, production, and flight-test teams, as well as the support of the company’s global network of partners.
“This inaugural flight is another milestone for Dassault,” said Chairman and CEO Eric Trappier.
“It is a reflection of the dedication and high skill of our engineering, production, and flight teams, and also the quality of our global network of partners. All of us are excited to see this day as we launch into a new phase for the 10X.”
Aircraft performed as planned
The Falcon 10X program has been years in the making, involving thousands of employees and suppliers. Test pilot Sébastien Dupont de Dinechin noted that the aircraft performed as planned throughout the flight, highlighting the extensive effort invested in bringing the aircraft from concept to reality.
The flight-test program is expected to expand rapidly. A second test aircraft is nearing completion and will soon join the campaign, while a third aircraft equipped with a full interior will be used primarily for systems evaluation, cabin functionality assessments, and reliability testing.
The Falcon 10X is positioned as the flagship of Dassault’s Falcon family and is designed to set new standards in business aviation through a combination of advanced technology, long-range capability, and passenger comfort. The aircraft is expected to compete in the ultra-long-range segment, serving customers who require intercontinental travel with enhanced efficiency and luxury.
Dassault Aviation emphasized that it is currently the only aircraft manufacturer flying an entirely new aircraft type in 2026, underscoring the company’s continued commitment to innovation. The achievement also reflects the benefits of Dassault’s unique expertise across both civil and military aviation sectors, which has long been a cornerstone of the company’s success.
With more than a century of aerospace experience and over 10,000 aircraft delivered worldwide, Dassault Aviation continues to strengthen its position as one of the leading manufacturers of high-end business jets. The successful maiden flight of the Falcon 10X marks the beginning of a new chapter for the company and brings the aircraft one step closer to entering service.

A new study published in Nanotechnology journal Nature Publishing Group’s Nature Nanotechnology has found that microscopic boron nitride nanotubes can transport lithium ions at speeds far greater than previously expected.
These tiny tube-shaped channels were shown to selectively move lithium ions while blocking many other ions, effectively creating a high-speed pathway for lithium transport. The findings suggest that boron nitride nanotubes could serve as a promising platform for next-generation separation technologies.
Potential applications include clean energy production, including blue energy systems that generate power from the mixing of saltwater and freshwater, as well as more efficient lithium extraction for battery manufacturing.
New ion transport mechanism surpasses theoretical expectations
According to Sangil Kim, the newly identified transport mechanism enables lithium ions to move through nanotubes at exceptionally high speeds. Kim, an associate professor of chemical engineering at University of Illinois Chicago and co-author of the study, noted that the observed ion transport rates significantly exceeded both theoretical predictions and results reported in existing experimental systems, highlighting the unusual efficiency of the nanotube-based approach.
Efficient ion transport plays a critical role in a wide range of industrial applications. When salts dissolve in water, they split into positively and negatively charged ions that travel through nanochannels at varying speeds. Managing and controlling this ion movement across membranes is essential for advancing technologies such as batteries, desalination systems, critical mineral extraction, and renewable energy generation.
Still, balancing fast ion movement with high selectivity remains a major scientific and engineering challenge. In this study, the researchers developed membranes containing millions of tiny boron nitride nanotubes, which have charged surfaces and unusual transport properties. When placed between solutions with different salt concentrations, the membranes allowed ions to pass through much more quickly than expected.
Lithium ions stood out in particular, moving about 31 times faster than predicted. The results also showed strong selectivity, with lithium ions traveling through the channels significantly faster than other types of ions.
Electric eel-inspired system turns ion flow into usable energy
To demonstrate the potential of the system, Kim and his team showed that the small membranes could generate enough energy from salt solutions to power simple electronic devices. Kim noted that they were able to operate a watch and a calculator using this approach.
The concept of producing electricity from ion movement is not new, and as Kim explained, electric eels use a similar principle in nature, generating electrical bursts by controlling ion flow across specialized cells known as electrocytes.
Electrocytes rely on ion channels to convert chemical gradients into electrical energy, a natural process that has long inspired efforts to replicate similar mechanisms in engineered systems, including the membranes developed in this study.
Going forward, Kim and his team aim to explore additional applications for the technology, with a particular focus on the nanotubes’ ability to separate lithium. He noted that the findings could potentially be used for lithium recovery from waste batteries, with the team also planning to investigate the underlying physics in more detail to better understand what drives the unusually fast ion transport observed in the system.
Researchers at the University of Illinois Chicago have developed a new class of nanotube membranes that enable exceptionally fast lithium-ion transport.

A driver told Harris County investigators that his Tesla was on Autopilot before it left a residential road in Katy, Texas, crashed through the brick wall of a home, and killed a 76-year-old woman inside.
The crash happened around 8 p.m. Friday in the 21300 block of Rose Hollow Lane, according to the Harris County Precinct 5 Constable’s Office and the Harris County Sheriff’s Office.
