Get ready for another BIG and BRILLIANT adventure into the world of science on this week’s Science Weekly!

In Science in the News, we reveal what lies hidden beneath Antarctica’s ice, explore why scientists are rethinking what they know about cows after one was seen using objects to solve a problem., and hear from Callum Harrison at the British Geological Survey about what’s happening beneath our feet after more than 300 earthquakes shook the UK last year.

Then it’s time for your questions. Willie wants to know what the electromagnetic spectrum is, and Joe Williams from Exeter University answers a mind-bending question: if energy can’t be made or destroyed, how was it first created?

Dangerous Dan is back with a plant you really do not want to touch as we meet the giant hogweed.

And in Battle of the Sciences, we explore the powerful science of toxicology and why understanding poisons and chemicals matters more than you might think.

Plus, head to Deep Space High Earth Watch, where Professor Pulsar teaches Sam all about Earth’s movements, including earthquakes and volcanoes.

This week, we learn about:

• Where energy comes from

• The hidden dangers and powers of toxicology

• Earthquakes and what causes them

• What’s beneath Antarctica’s ice

• The science behind vibrations and movement inside the Earth

All that and more on this week’s Science Weekly
