Ammonia from massive penguin guano deposits reacts with sulfur gases to form aerosol particles, seeding clouds over Antarctica. Measurements near a 60,000-strong Adélie colony showed ammonia levels 1,000× above baseline, triggering fog and cloud droplets that may help cool the surface.

Les manchots aident à refroidir l’Antarctique

MONGABAY

Le guano de manchot libère de l’ammoniac qui, en réagissant avec des gaz soufrés, forme des particules favorisant les nuages. Près d’une colonie d’Adélie, les taux d’ammoniac sont 1 000 fois supérieurs à la moyenne, ce qui pourrait rafraîchir la région.

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.

A recent Carbon Brief study shows China’s carbon dioxide emissions have remained unchanged or declined for 18 straight months, thanks in part to a surge in solar (+240 GW) and wind (+61 GW) capacity and a 5% drop in transport emissions.

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.

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.
