A Cincinnati-based aerospace company has successfully represented a new, cutting-edge hypersonic dual-mode ramjet. The engine could enable high-speed flight and longer range across numerous multi-mission aircraft.
GE Aerospace took 11 months to develop the ramjet, which could increase in airflow compared to previously flight-tested hypersonic technology demonstrators.
“The rapid progression from design to testing underscores our commitment to driving innovation in hypersonic technologies,” said Amy Gowder, president and CEO of Defense & Systems at GE Aerospace.
A super-sized Nano Transparent Screen (NTS) has been developed and commercialized for the first time in the world. This innovative screen can adjust its transparency according to the environment and can be produced at a low cost, paving the way for the widespread adoption of large transparent screens, which until now have been prohibitively expensive.
A global research team has devised a method to decompose plastics and other materials into their smallest components using a laser, enabling their future reuse.
The breakthrough involves placing these materials on two-dimensional structures called transition metal dichalcogenides and then exposing them to laser light. This technique could significantly enhance the disposal of plastics that are currently almost impossible to break down with existing technologies.
Researchers have developed a new method to significantly enhance quantum technology performance by using the cross-correlation of two noise sources to extend coherence time, improve control fidelity, and increase sensitivity for high-frequency sensing. This innovative strategy addresses key challenges in quantum systems, offering a tenfold increase in stability and paving the way for more reliable and versatile quantum devices.
The work is published in the journal Physical Review Letters.
Researchers have made a significant breakthrough in quantum technology by developing a novel method that dramatically improves the stability and performance of quantum systems. This pioneering work addresses the longstanding challenges of decoherence and imperfect control, paving the way for more reliable and sensitive quantum devices.
“Forget about essences.” Philosopher Daniel Dennett on how modern-day philosophers should be more collaborative with scientists if they want to make revolutionary developments in their fields.

Philosophy and science haven’t always gone hand-in-hand. Here’s why that should change.
Daniel Dennett, an Emeritus Professor from Tufts University and prolific author, provides an overview of his work at the intersection of philosophy and science. Many of today’s philosophers are too isolated in their pursuits, he explains, as they dedicate their intellect purely to age-old philosophical ideas without considering the advancements of modern science. If our understanding of reality evolves with every new scientific breakthrough, shouldn’t philosophical thought develop alongside it?
In just 11 minutes, Dennett outlines the four eras he evolved through on his own journey as a philosopher: classical philosophy, evolutionary theory, memetic theory, and the intentional stance. Each stage added depth to his perspective and understanding, enriching his personal journey as a philosopher and his analysis of how philosophy, when used correctly, can help us comprehend human behavior.
Dennett’s key takeaway is a request for philosophers to reevaluate their methodologies, urging modern-day thinkers to embrace the insights offered by new scientific discoveries. By combining the existential and theoretical viewpoints of philosophers with the analytical and evidential perspective of scientists, we can begin to fully and accurately interpret the world around us. Maybe, with this type of collaboration, we can begin to answer the questions that started our intellectual pursuits in the first place, so many hundreds of years ago.
