In this week's podcast, Richard Hollingham strikes gold - literally - while Sue Nelson finds out why weather forecasters still struggle to predict sudden, violent summer storms. We'll also be hearing why scientists may be a step closer to getting rid of the American mink from the Outer Hebrides and how to run away from a Tyrannosaurus rex. Banks may have collapsed, shares plummeted

Mention the word archaeology and you might conjure up an image of Tony Robinson from Channel 4's Time Team getting down to a dig in an ancient burial site in an attempt to find some telling artefacts. But these days, people researching the ancient past have some additional, very sophisticated tools up their sleeves. Richard Hollingham visits the Natural Environment Research Council

This week we talk to two researchers about the technological solutions some scientists say we might have to use to tackle climate change. With average temperatures expected to rise by 2C this century, and efforts to cut greenhouse emissions proving painfully slow so far, scientists are saying it might be prudent to have a plan B. Professor Tim Lenton and Dr Nem Vaughan from the Uni

Willow, palm, miscanthus and other energy crops are being touted as a possible solution to our growing energy security problems. Some people are suggesting that they could help replace fossil fuels, plugging Britain's energy gap and cutting our carbon footprint.But before we go down that route, wouldn't it be sensible to find out how these crops affect the environment?That's the ve

Coral reefs are among the most beautiful habitats in the world. As well as being rich in biodiversity, they're vital for the local economies that depend on them for fishing, tourism or protection from storms.While most of us are aware that ocean acidification is bad for coral reefs, scientists are now finding that coral communities are facing other threats from climate change.Richa

Look around the English countryside and you'll find animals and plants that shouldn't be there - from Muntjac deer to Mitten crabs, Harlequin ladybirds to Tree of Heaven.So-called invasive species are reckoned to be one of the world's greatest threats to native wildlife. And when you factor in a changing climate, the situation gets even more complicated.Richard Hollingham meets an

In this week's Planet Earth podcast from the impressively-named Diamond Light Source in Oxfordshire, England, hear how two researchers are using hi-tech physics to study different aspects of the environment.The Diamond synchrotron is like a giant, silver doughnut, is more than half a kilometre around and - according to the blurb - you could fit eight St Paul's cathedrals inside.You

You could be forgiven for thinking the freezing seas around Antarctica are pretty barren and lifeless. But, as Richard Hollingham soon finds out, this couldn't be further from the truth.The Census of Marine Life is building up a picture of the richness and diversity of life in the world's oceans and has so far found thousands of species on shelves around the frozen continent. Incre

Everyone loves a rockpool, and Sue Nelson nearly takes a dive into one in this week's podcast while finding out about the riches they contain. She visits the Anglesey coast of north Wales to learn what these mini marine laboratories can tell us about the value of biodiversity. The effects of climate change range from rising temperatures and higher sea levels to extreme weather and

British Geological Survey scientists have completed the first full geological survey of Lake Windermere in the English Lake District since the Royal Navy made a survey in the 1930s. Among other things, the survey will help researchers understand how quickly the ice retreated after the last Ice Age, how the lake evolved and which parts the Arctic Charr prefers to live in.
