How B-2 bombers vanish from radar.

This simulation shows how electromagnetic waves interact with stealth aircraft surfaces.

The B-2 Spirit uses engineered shapes, radar-absorbing materials, and coatings to scatter incoming waves instead of reflecting them back

U of T study finds that whole-fat milk lowers risk of child obesity New research from the University of Toronto suggests that children who drink whole-fat milk in early childhood may have lower odds of obesity in middle childhood than those who drink reduced-fat milk.

Study finds that whole-fat milk lowers risk of child obesity

"It’s important to consider the overall nutritional context. Removing fat does not automatically make skim milk a healthier choice for children”

Focusing on color: How the eye chooses which wavelength to see best Evidence suggests that human vision uses opposing color signals (red-green and blue-yellow) to bring the world into focus.

New study finds eye focuses using color signals, not just sharpness

Overcoming the Indirect Band Gap: Efficient Silicon Emission via Momentum-Engineered Photonic States Silicon’s indirect band gap severely suppresses radiative recombination, limiting its use as an efficient light-emitting material. Although nanoscale confinement of carriers, dielectric resonators, or plasmonic structures can partially mitigate this limitation, these approaches typically require complex fabrication. Here we report a fundamentally different and scalable mechanism that enables efficient light emission directly from bulk silicon. By decorating a silicon wafer with ultrasmall (<2 nm) gold or copper particles, we observe intense luminescence spanning the visible and near-infrared. Remarkably, the emission is indistinguishable for Au and Cu decorations in both spectral and temporal domains, demonstrating that the confinement extent, not the material composition, governs the effect. We attribute the emission to spatially confined photonic states with broadened momentum distributions, enabling phonon-independent optical transitions otherwise forbidden in silicon. This mechanism yields quantum efficiencies comparable to direct-band-gap semiconductors and produces ∼105-fold enhancement in the integrated emission intensity, establishing a practical route toward silicon light-emitting devices.

Researchers have demonstrated a fundamentally new way to make silicon emit light

This shows that silicon, long considered an inefficient light emitter due to its indirect bandgap, can be transformed into a bright, broadband source

Giant Atoms for Measuring Radiation The invention of the radio just over a century ago transformed people’s ability to communicate.

The next big leap in radio communication might not be a bigger antenna. It could be a “giant” atom.
