Affordable, room-temperature maser created using LED technology

With the ability to detect and amplify extremely weak electromagnetic signals without adding additional noise, masers have many potential uses, including the production of more sensitive magnetic resonance body scanners, such as those used in airports.

Despite their discovery in the 1950s, there has been little development of the technology since then due to the complex and expensive conditions required to make them—masers are only able to be produced in very cold conditions, while also within a vacuum and a high magnetic field.

Northumbria’s Dr. Juna Sathian is one of the U.K.’s leading experts in maser technology and has previously worked with colleagues at Imperial College London and University College London to develop a room-temperature maser which works using laser light. However, this method is expensive and difficult to replicate in everyday applications.

New lithium-sulfur battery for electric cars reduces charging time to 12 minutes

Researchers from Germany, India and Taiwan have presented the concept of lithium-sulfur batteries for electric cars, which will reduce the full charging time to less than 30 minutes.

With the global transition to electric transportation, reducing battery charging time remains one of the key challenges for developers and researchers around the world. Modern Li-ion batteries can be charged from 20 to 80% in about 20–30 minutes, but full charging takes much longer. Meanwhile, high-speed charging leads to a shorter battery life.

The study, conducted by researchers from Kiel University and their colleagues from India and Taiwan, suggests that lithium-sulfur batteries can solve the existing problems. The international study led by Dr Mozaffar Abdollahifar provides a detailed description of how lithium-sulfur batteries can overcome the limitations of current Li-ion batteries in terms of performance and charging time.

Targeting MXenes for sustainable ammonia production

In a hunt for more sustainable technologies, researchers are looking further into enabling two-dimensional materials in renewable energy that could lead to sustainable production of chemicals such as ammonia, which is used in fertilizer.

This next generation of low-dimensional materials, called MXenes, catalyzes the production of air into ammonia for foods and transportation for high-efficiency energy fertilizers.

MXenes has a wide range of possibilities that allow for highly flexible chemical compositions, offering significant control over their properties.

Wood-based material can improve safety and lifespan of lithium-ion batteries

For consumers worried about the risks associated with using lithium-ion batteries—which are used in everything from phones to laptops to electric vehicles—Michigan State University has discovered that a natural material found in wood can improve battery safety while also improving the battery’s life.

Chengcheng Fang, assistant professor in the College of Engineering, and Mojgan Nejad, an associate professor in the College of Agriculture and Natural Resources, collaborated to engineer , a natural ingredient of wood that provides support and rigidity, into a thin film separator that can be used inside to prevent short circuits that can cause a fire.

“We wanted to build a better battery,” said Fang. “But we also wanted it to be safe, efficient and sustainable.”

Ford CEO Admits Defeat With SHOCKING Comments

“This Plane Just Did the Impossible”: Historic Supersonic Flight Silences the Sky with Zero Sonic Boom for First Time Ever

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.

RisingAttacK: New technique can make AI ‘see’ whatever you want

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 , pedestrians or other cars—which would cause problems for . 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 ,” 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.

Mathematical approach makes uncertainty in AI quantifiable

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.
