• Rare goblin shark filmed alive for the first time in the deep sea

  For the first time, researchers have filmed the elusive goblin shark alive in the deep ocean where it naturally lives. The remarkable sightings greatly expand the shark's known range and depth, showing that this 125-million-year-old "living fossil" still has plenty of secrets left to reveal.

• Ancient DNA reveals the mysterious collapse of Europe's megalith builders

  DNA from a 5,000-year-old French megalithic tomb reveals that the people buried before and after a population collapse were genetically unrelated, pointing to a major migration after a devastating crisis. The shift coincided with new social traditions and the disappearance of the communities that built Europe's giant stone monuments.

• Bumblebees collect up to 7 times more toxic metals than honeybees

  Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies healthy.

• New research reveals the hidden pollution left behind by fireworks

  Scientists have uncovered new evidence that fireworks can pollute both the air and water in ways that extend beyond the visible smoke. The findings show that leftover debris, fine particles, and airborne chemicals may affect ecosystems and increase people's exposure to air pollution during major celebrations.

• Scientists finally crack nature's secret for building better cancer drugs

  Researchers have cracked the code behind bacteria's ability to naturally manufacture multiple versions of powerful anti-cancer drugs. The discovery could make it much easier to engineer new cancer treatments inspired by nature, including improved versions of existing medicines.
