Researchers at King’s College London found that keratin—the protein in hair, skin, nails, and wool—can mimic enamel by interacting with saliva minerals to restore lost tooth surface. A sustainable, stronger, and more natural path to cavity repair may be just a few years away.

Scientists at TU Wien have developed a non-toxic “deep-eutectic” solvent that separates blended fabrics — like cotton-polyester mixes — within minutes. Cotton stays intact and polyester is recovered almost fully, offering a near-complete recycling method for textiles that were once nearly impossible to reclaim.

At COP30 in Belém, Brazil officially created ten new Indigenous territories, including some overlapping Amazon National Park. The move, issued via presidential decree, adds legal protection to lands of groups like the Munduruku and Guarani-Kaiowá during a summit marked by protests.

Researchers at the University of Cologne have discovered a powerful antibody — 04_A06 — that neutralizes around 98.5 % of over 300 tested HIV strains. In lab experiments the antibody reduced viral load to undetectable levels — a major step toward broad-spectrum therapies for prevention and treatment worldwide.
