Infrared to full-color vision: quantum-dot OLEDs redefine night sensing

A Beijing Institute of Technology team developed a prototype that converts infrared light into full-color images using mercury telluride quantum dots and a two-layer OLED, mapping wavelength and intensity to distinct colors rather than grayscale. Demonstrated in a lightweight wearable eyeglass and explored for next-generation retinal prosthetics, the system can produce color-coded infrared images and even elicit brain/retinal responses in tests. While promising for richer infrared information, the approach faces real-world limitations: controlled-environment testing, a powered OLED layer, and safety concerns around mercury telluride, needing further research before practical deployment.

Omnidirectional 3D-printed cloak erases heat signatures from infrared cameras

University of Illinois Urbana-Champaign researchers have developed a 3D-printed, aluminum-rubber lattice cloak that guides heat around objects, effectively erasing their infrared signatures from all directions and even cloaking complex shapes like a human head, with potential applications in microchip cooling and defense; the work, published in Nature Communications, signals a new approach to omnidirectional thermal cloaking.

Webb’s Four-Year Gallery: 25 Stunning Space Images

To mark JWST’s fourth birthday, the piece curates 25 images from the James Webb Space Telescope that merge scientific insight with beauty—from planetary closeups of Jupiter, Saturn, Uranus and Neptune to iconic deep-field and gravitationally lensed views like SMACS 0723 and SDSS J1226+2152—showcasing Webb’s infrared capabilities (MIRI and NIRCam) and its power to reveal dusty star-forming regions and the universe’s earliest galaxies.

Webb and Hubble Team Up for a Layered Portrait of Saturn

NASA, ESA and CSA released new Saturn images from the James Webb Space Telescope and Hubble that reveal different atmospheric layers: Hubble’s visible-light photos show color bands and storms, while Webb’s infrared view highlights deep clouds, aerosols, and the rings’ ice; taken in Aug 2024 (Hubble) and a few months later (Webb), the pair helps scientists study Saturn’s atmosphere across depths and track seasonal changes as it moves toward the 2025 equinox, with future observations promising even clearer southern-hemisphere views.

Ink of the Ancients: 2,000-Year-Old Siberian Mummy Unveils Hand-Poked Tattoos

Researchers using infrared imaging uncovered detailed tattoos on a 2,000-year-old Pazyryk mummified woman from Siberia, revealing designs from simple floral patterns to complex scenes on her forearms. The tattoos, likely culturally meaningful, were applied by hand-poking with multiple tools, underscoring sophisticated ancient craftsmanship and suggesting tattoos played a role in personal or social identity.

Webb’s Lava-Lamp View of the Eye of God: Helix Nebula Revealed

Astronomers using the James Webb Space Telescope have released a highly detailed infrared image of the Helix Nebula (NGC 7293), a nearby planetary nebula nicknamed the Eye of God. The image shows hot gas winds from a dying star colliding with older shells of gas and dust, revealing comet-like knots and layered structures, and offering a glimpse of our Sun’s distant future as well as the potential for planet formation in the surrounding dust.
