Get ready for another action-packed adventure into the world of science on this week’s Science Weekly. We’re travelling back to the dawn of time to uncover how Earth was created and meeting some of the planet’s oldest and most extraordinary residents.

In Science in the News, we explore why UK woodlands are facing a huge crisis, discover the shocking behaviour of rats in Germany, and hear from Connor Bamford from the British Antarctic Survey about what’s been happening to elephant seals in the South Atlantic.

Then it’s time for your questions. EJC wants to know how hydrochloric acid cleans pennies, and Joe Williams from Exeter University explains exactly how Earth formed in the first place.

Dangerous Dan is back with a creature straight out of a horror movie: The Zombie Snail Parasite.

And in Battle of the Sciences, May Chemais from the Ancient Tree Inventory joins us to reveal why ancient trees are some of the greatest survivors on Earth.

Plus, K-Mistry and Kareena dive deep into the oceans to uncover how they absorb CO2, why they’re at risk from climate change, and what we can do to help.

This week, we learn about:

• How Earth was created• Why UK woodlands are in trouble• The surprising hunting skills of German rats• What’s happening to elephant seals in the South Atlantic• The terrifying zombie snail parasite
