Humans may have returned to Britain far earlier than scientists once believed — not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of reindeer and horses across a landscape that was suddenly becoming warmer and greener.

Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests. Much of the pollution appears to come from vehicle emissions, likely linked to engine oil additives that survive combustion and escape into the air. Scientists say humans may inhale more of these c...

Researchers created a special kind of algae that can grab microscopic plastic pollution out of water almost like a magnet. The algae produce limonene, an orange-scented oil that helps them bind to water-repelling microplastics, forming easy-to-remove clumps. As a bonus, the algae also clean wastewater while growing.

The Toba supereruption 74,000 years ago was so massive it may have plunged Earth into years of darkness and cold, leading some scientists to believe humanity nearly went extinct. Yet archaeological evidence from Africa and Asia suggests early humans were far more resilient than once thought. Instead of disappearing, some communities adapted with new tools, new survival strategie...

A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel. Even more impressive, it could replace costly titanium parts used in today’s hydrogen systems.
