Earth faces a significant threat from thousands of undetected asteroids capable of destroying cities. NASA's planetary defence chief warns that current systems cannot reliably stop these 'city-killers'. While progress is being made with new telescopes and international efforts, a substantial gap remains in our ability to detect and deflect such objects before they impact our planet.

Romanian scientists have revived a 5,000-year-old bacterium, Psychrobacter SC65A.3, from Scărișoara Ice Cave, revealing resistance to 10 modern antibiotics. The discovery highlights natural, ancient origins of antibiotic resistance and warns that melting ice could release genes into contemporary bacteria. At the same time, these cold-adapted microbes hold potential for new antibiotics, enzymes, and biotechnological innovations, underscoring both risk and opportunity.

Australian farmers are finding a new use for surplus sheep's wool. This low-value wool is now being spread on drought-hit fields. It helps soil retain moisture and rebuilds its structure. This approach is showing measurable gains in soil health. It also creates new markets for wool and supports rural jobs. This innovative practice is gaining attention globally.
