The retina, the thin layer of tissue at the back of the eye, is made up of photoreceptor cells that convert visible light into electrical signals, which is essential for human vision. Some diseases, such as retinal degeneration, ...

Hydrogen is often described as the fuel of the future—a clean, energy-dense way to store renewable power and decarbonize industries from steelmaking to shipping. But inside the devices that produce it, a surprisingly small ...

Kodak invented the digital camera in 1975. Management looked at it, decided film was doing fine, and put the technology in a drawer. By the time they took it seriously, other companies had taken the market. Kodak filed for ...

OpenAI released a new model it touts as its best yet for handling research work like making improved versions of itself, as rapid-fire releases by AI rivals pick up pace.

Penn Engineers have developed SmartDJ, an AI-powered editor that lets users modify immersive audio environments with simple instructions in everyday language, with potential applications in virtual reality, augmented reality, ...

In the race to make AI models not just reason better but respond faster, latency—the delay before an answer appears—is often treated as a purely technical constraint, something to minimize and move past. But how is this relentless ...

Princeton researchers have combined brain cells and advanced electronics into a single 3D device that can be programmed to recognize patterns using computational techniques. Past attempts at using brain cells to do computation ...

Smartphones, electric vehicles and many portable devices rely on batteries. Their energy storage capacity, lifetime and safety will strongly shape the future of electrification. Among the most promising next-generation technologies ...

When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked a different question: ...

Metal-organic frameworks, better known as MOFs, are among the most intensely studied materials for addressing major environmental challenges. Their highly ordered, ultra-porous architecture enables applications ranging from ...

Acrylic acid is essential for everyday products—from paints and coatings to absorbent polymers—yet almost all of it is currently made from propylene, a petrochemical. As global biodiesel production rises, so does the supply ...

Perovskite solar cells, PSCs, have emerged as one of the most promising renewable energy technologies of the past decade. Besides their remarkable power conversion rates, perovskites are lightweight in nature and can be manufactured ...
