Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors to capture sharp, wide-range images without distortion. It can also create precise 3D reconstructions even in extremely low light. Though still experimental, the technology promises affordable, portable infrared imaging for safety, industrial, and environmental uses.

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the cosmic web, then validated the results with observations. Their study sets a stricter upper limit on the fields’ strength, aligning with other data and suggesting important consequences for early star and galaxy formation.

Researchers have built a self-assembled nanocage with a very unusual nanospace: Its walls are made of antiaromatic molecules, which are generally considered too unstable to work with. By overturning assumptions about the limits of nano-chemical engineering, the study creates an entirely new nanospace for scientists to explore. Nanometer-sized cavities are already finding a range of useful applications in chemistry, medicine and environmental science.
