The aviation industry witnessed a monumental breakthrough on February 10, 2025, as Boom Supersonic’s XB-1 aircraft accomplished what many experts deemed impossible. Flying over the Mojave Desert at speeds exceeding the sound barrier, the aircraft achieved something unprecedented in aviation history: supersonic flight without generating a sonic boom. This revolutionary achievement has opened new possibilities for the future of air travel.
For decades, the notorious sonic boom has been the Achilles’ heel of supersonic travel. When aircraft exceed the speed of sound (approximately 761 miles per hour at sea level), they create powerful shock waves that culminate in the distinctive thunderous crack heard on the ground. This disruptive phenomenon has historically restricted supersonic flights to ocean routes, as demonstrated by the iconic Concorde.
Boom Supersonic’s XB-1 has changed this narrative through its implementation of Mach cutoff technology. This innovative approach exploits atmospheric conditions to redirect shock waves upward rather than toward the ground. By carefully selecting specific flight altitudes and analyzing atmospheric data, the aircraft effectively minimizes the impact of these pressure waves.
Researchers have demonstrated a new way of attacking artificial intelligence computer vision systems, allowing them to control what the AI “sees.” The research shows that the new technique, called RisingAttacK, is effective at manipulating all of the most widely used AI computer vision systems.
At issue are so-called “adversarial attacks,” in which someone manipulates the data being fed into an AI system to control what the system sees, or does not see, in an image. For example, someone might manipulate an AI’s ability to detect traffic signals, pedestrians or other cars—which would cause problems for autonomous vehicles. Or a hacker could install code on an X-ray machine that causes an AI system to make inaccurate diagnoses.
“We wanted to find an effective way of hacking AI vision systems because these vision systems are often used in contexts that can affect human health and safety—from autonomous vehicles to health technologies to security applications,” says Tianfu Wu, co-corresponding author of a paper on the work and an associate professor of electrical and computer engineering at North Carolina State University.

How reliable is artificial intelligence, really? An interdisciplinary research team at TU Wien has developed a method that allows for the exact calculation of how reliably a neural network operates within a defined input domain. In other words: It is now possible to mathematically guarantee that certain types of errors will not occur—a crucial step forward for the safe use of AI in sensitive applications.
From smartphones to self-driving cars, AI systems have become an everyday part of our lives. But in applications where safety is critical, one central question arises: Can we guarantee that an AI system won’t make serious mistakes—even when its input varies slightly?
A team from TU Wien—Dr. Andrey Kofnov, Dr. Daniel Kapla, Prof. Efstathia Bura and Prof. Ezio Bartocci—bringing together experts from mathematics, statistics and computer science, has now found a way to analyze neural networks, the brains of AI systems, in such a way that the possible range of outputs can be exactly determined for a given input range—and specific errors can be ruled out with certainty.
BYD, an electric vehicle company, is accused of cooking the books and faking profitability, potentially hiding financial issues such as a liquidity crisis and unprofitable electric vehicle business.
Questions to inspire discussion.
Financial Concerns 🚩 Q: What are the warning signs of BYD’s potential financial trouble? A: BYD is offering massive discounts of 10–30% on already affordable vehicles, with some models selling for as low as $10,000, and allegedly has a 12-month payment delay to suppliers. 💰 Q: How is BYD’s automotive business reportedly staying afloat? A: BYD’s automotive business is allegedly being carried by their highly profitable battery cell supply business, which is not separately reported in their financials, making it difficult to determine the true profitability of their electric vehicle sales.

Strengthening the competitiveness of the American transportation industry relies on developing domestically produced electric vehicle batteries that enable rapid charging and long-range performance. The energy density needed to extend driving distance can, however, come at the expense of charging rates and battery life.
By integrating a new type of current collector, which is a key battery component, researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated how to manufacture a battery with both superior energy density and a lasting ability to handle extreme fast charging. This enables restoring at least 80% of battery energy in 10 minutes. By using less metal, particularly high-demand copper, the technology also relieves strain on U.S. supply chains.
“This provides a significant savings on near-critical materials, because much less copper and aluminum are needed,” said lead researcher Georgios Polyzos. “At the same time, this will greatly enhance the energy density achievable with a 10-minute charge.”
Methane (CH4), one of the most abundant natural gases on Earth, is still widely used to power several buildings and to fuel some types of vehicles. Despite its widespread use, storing and transporting this gas safely remains challenging, as it is highly flammable and requires compression at high pressures of around 25 megapascals (MPa).
Most existing solutions to store CH4 at high pressures rely on expensive equipment and infrastructure, such as reinforced tanks, specialized valves and advanced safety systems. In addition, damage to this equipment or its malfunction that prompts leakage of gas can lead to explosions, fires and other serious accidents.
Some researchers have thus been trying to devise alternative strategies to store and transport CH4 that are both safer and more cost-effective. One of these recently proposed methods, known as absorbed natural gas (ANG), entails the use of nanoporous materials, solid materials containing tiny pores in which gas molecules could be trapped at moderate pressures.
