The Other Side

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon atoms to slip through the metal. This slows diffusion at the atomic level and alters steel’s internal structure. The insight could lead to more efficient, lower-energy ways to make stronger steel.

When materials become just one atom thick, melting no longer follows the familiar rules. Instead of jumping straight from solid to liquid, an unusual in-between state emerges, where atomic positions loosen like a liquid but still keep some solid-like order. Scientists at the University of Vienna have now captured this elusive “hexatic” phase in real time by filming an ultra-thin silver iodide crystal as it melted inside a protective graphene sandwich.

Webb’s latest image of the Helix Nebula reveals a dramatic close-up of a dying star shedding its outer layers. The detailed view highlights glowing knots of gas shaped by fast-moving stellar winds colliding with older material. Changes in color trace a shift from scorching hot gas near the center to cooler regions farther out. The scene captures how stellar death helps supply the building blocks for future worlds.

Home fireplaces and wood stoves are quietly driving a large share of winter air pollution, even though only a small number of households rely on wood heat. Researchers found that wood smoke accounts for over one-fifth of Americans’ winter exposure to dangerous fine particles linked to heart disease and early death. Much of this pollution drifts into cities, where it disproportionately harms people of color. Reducing wood burning could deliver major public health benefits.

Cancer doesn’t evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that help tumors grow, adapt, and survive treatment. By tracking thousands of individual cells over time, the approach shows which chromosome combinations give cancer an edge and why some tumors become especially resilient.
