Radioactive 'pooh sticks' trace carbon's ocean journey

Scientists say the contaminants take a circuitous route travelling via the Arctic Ocean and down past Greenland. Researchers believe the radioactivity levels are extremely low and present no danger. However, scientists can use the iodine to accurately map the currents that transport greenhouse gases.

As well as helping eliminate polio, the scientists believe their approach could help the world react to unexpected threats such as Zika virus or Ebola. Experts said the achievement was both impressive and important. The vaccine is an "authentic mimic" of poliovirus called a virus-like particle. Outwardly it looks almost identical to poliovirus but - like the difference between a mannequin and person - it is empty on the inside.

Armoured tank-like dino used camouflage to hide

The exquisite specimen is a type of amour-plated nodosaurid ankylosaur. It was camouflaged which suggests that, despite its tank-like appearance, it hid to avoid predation.

A new species of dinosaur named Borealopelta markmitchelli has been discovered from an oil sand mine in Alberta, Canada, and is described this week in Current Biology.
