• A rare cancer-fighting plant compound has been decoded

  Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule’s unusual twisted structure, solving a mystery that had puzzled researchers for years. Because mitraphylline appears only in tiny amounts in tropical plants like kratom and cat’s claw, the discovery could make it far easier to produce sustainably in the future.

• Scientists discover a mysterious silicone pollutant that may be everywhere

  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 compounds daily than other notorious pollutants like PFAS or microplastics.

• Cacti are evolving shockingly fast and scientists just learned why

  Cacti may look like slow, stubborn desert survivors, but they’re actually evolving at lightning speed. Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn’t flower size or specialized pollinators, but how quickly cactus flowers change shape over time. The finding overturns a long-standing idea dating back to Darwin and reveals deserts as surprisingly dynamic ecosystems where evolution is happening fast.

• Scientists say this algae could remove microplastics from drinking water

  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.

• Humans returned to Britain 500 years earlier than scientists thought after the last ice age

  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.
