How is Gold formed? Could hydrogen be used in power plants? How small can an atomic bomb be? Could we reverse electrolysis to make water? We tackle these questions in this week's show as well as find out how the shrunken heads in Borneo are shrunk, why burnt toast goes black, and why white bread is white. Plus, we investigate if bullets can be made from custard and whether we can trap light to use as energy!

in this NewsFlash, we'll be hearing about the camouflaged plant that doesn't need the Sun, a power plant that relies on osmosis and how the feeling of breath on your skin helps you to work out what sounds you're hearing. Plus, we look back to this week in Science History and the first meeting of the Royal Society.

How wide is the universe? What makes steak tough? Why does beetroot give me red urine? These tricky questions get stripped down in this Naked Scientists Question and Answer show. We'll be hearing about the camouflaged plant that doesn't need the Sun, a power plant that relies on osmosis and how the feeling of breath on your skin helps you to work out what sounds you're hearing. Also, in Kitchen Science, we use straws and a cup of water to show you how airbrushes and carburettors work!

This week's question is all about the cell-zapping power of radiation. Just how much does a standard medical scan expose you to? How does that compare to the levels radiation workers are limited to receiving? Plus, we ask how seedless fruits manage to reproduce.

This week we look into our crops and agriculture to learn how scientists are improving farming methods to meet the food demands of the world's increasing population. We discover how monitoring plants with cameras and lasers can help us understand and improve them, plus how plants can be altered to survive in salty soils. We also learn how to pick the best brapes for making wine and in question fo the week we reveal the best way to serve it!

Can we re-set our body clocks? How can we ease the effects of jetlag? Do body clocks change with age? We look into these questions in this week's show as well as investigate whether lightning can occur without clouds, the effects of head injuries, why spacecrafts need to travel at high speeds and we discuss the optimum world population.

Why is it that we serve white wines and red wines at different temperatures? Does this really affect the bouquet? Plus, we ask how many x-rays are too many.

This week, we head down under to explore the latest Australasian science - we'll discover the new, state-of-the-art facility where high-tech lasers and cameras breed the best plants; explore a new remedy for wine ruined by bush fires and find out why grapes killing themselves is the tip to a wonderful tipple. We also reveal, two new bowel-bugs that cause gastroenteritis and why porridge is good for your guts. Plus, we investigate the best temperatures for serving wine, in Question of the Week!

How can you measure how dark a place is? When do meteor showers occur and how can we see them? How do 'magic eye' paintings work? We reveal the answers to these mysteries in this week's show. We also find out whether the earth breathes, why car wheels appear to move backwards, and how DNA can narrow criminals down to a specific location. Plus, we investigate where all the hazelnuts have gone!

This we we explore our universe to discover how our stars and planets were formed and how satellites out in space can help us monitor our environment here on earth. We also bring you the latest news including how the smell of old books can help to preserve them, and how deleting old memories makes room for new ones. Plus, keep an eye on the sky, in Question of the week!

This week, we bring you the latest news from the world of science including the world's fastest camera and how higher heels make you a faster runner! We also discover the most distant object ever found and how the non-stick coating, PTFE, is bringing technological success to South Africa. Plus, we try to get a good signal, in question fo the week!

This week, we look into the latest developments in the field of fertility to see how scientists are trying to improve the conditions of in-vitro fertilisation, IVF. We also bring you the latest science news including how a babies cry depends on it's accent as well as reveal a new faster, cheaper way to sequence the human genome and discover how eating slowly may be better for your health. Plus, staying on the topic of fertility, we investigate how many children a sperm donor can father!

On this week's Naked Scientists, we seek the start of the solar system. We'll be finding out how clouds of gas and dust can clump and diversify to become stars, asteroids and the planets we know so well. Plus, we find out what happens to sculpt the surface of planets, and how the Rosetta mission will be the first craft to land on a comet! Also,how the smell of old books can help to preserve them, deleting old memories to make room for new ones and the frightening rate of Greenland ice loss. Plus, in Kitchen Science, Ben and Dave explain how margarine and meteorites tell us about Earth's origins!

On this week's Naked Scientists NewsFlash, how the smell of old books can help to preserve them, deleting old memories to make room for new ones and the frightening rate of Greenland ice loss. Plus, we look back to this week in Science history and the life of Nobel Laureate Daniel Nathans.

This month's edition of Naked Archaeology hails from Poseidon's Realm: we find out how synchrotrons can help in the preservation of the famous raised wreck, the Mary Rose and how diving diggers investigate entire ancient landscapes hidden beneath the seas. Plus, in Backyard Archaeology Tom Birch puts his mic to the anvil to find out about the deep dominion of archaeometallurgy.

We find out why it is we see red skies at all and the meteorology behind, Red sky at night, shepherd's delight; red sky in the morning, shepherd's warning. Is it true? Plus, we ask why different wines are served at different temperatures.

What is snot? Why do we make saliva? How do babies have such sweet smelling breath? These, and other less bodily questions, get tackled in this Ask the Naked Scientists. We find out how a radio can consume batteries quickly, where to live to avoid floods and if a brain scan can spot criminal intent!
