Good to know as you travel to the Antipodes - Australia has the most venomous snakes and spiders in the world. But, if you’re bitten, can you rely on anti-venom? Dr Graham Phillips investigates the effectiveness of anti-venom.
Thousands of chemicals are used in everyday products – in our water, our food and in the air we breathe. It’s the chemical soup of modern life and it’s virtually impossible to escape them. Is there adequate regulation and testing, or are we in the midst of an uncontrolled, human experiment?

The promise of quantum computers is that what would otherwise take a billion years to calculate, could be done in a few seconds. First-generation quantum computers have started to appear. Indeed, earlier this year, Google bought one, The D-Wave 2. How will this advance change our future lives?

What is memory? How do our memories change from childhood to adulthood? How we can build up greater brain reserves to power our mind into old age? Brain epigenetics, how the expression of our DNA can be changed by our experiences, is an intriguing new area of science with huge health implications.

Fifty meters beneath the teeming mega-city of Tokyo is an underworld river system - 6.4km of tunnels, colossal water tanks, massive pillars, giant pumps that remove 200 tons of floodwater every second. It’s an engineering marvel built to protect Tokyo against the increasing threat of flooding.

Why do we sleep? We spend a third of our lives in slumber, but science has yet to determine exactly why we have do it. Here’s a look at how sleep works, why we’re not getting enough sleep, what happens if you DON’T sleep, and an idea about where sleep came from in the first place.
So far the volunteers have successfully been losing lost weight, but now the honeymoon period is over. It is the final two months of the diet, and their minds and bodies are fighting back. Dr Chris van Tulleken and Professor Tanya Byron find out if the new personalised diets will help them stay on course, and the experts reveal the scientific secrets to permanent dieting success.
This time, we meet a man who feels no pain, a woman who can smell Parkinson's disease, a man who can remember every face he has ever seen and a survivor of a head injury who woke up to find he could suddenly play the piano. These remarkable cases are shedding new light on one of the most mysterious parts of the human body - our brain.
A treatment developed in Japan can dramatically improve stroke aftereffects such as paralysis. Until recently, medical experts thought that after 6 months, stroke patients would see little improvement, even with intensive rehabilitation. A treatment called transcranial magnetic stimulation, or TMS, is overturning that idea. Using magnetic pulses to stimulate the brain, it has helped people improve movement and speech, sometimes years after a stroke. We'll also learn how to spot a stroke and help with rehabilitation at home.
Not all the microbes that live on us or inside us are benign, and it is only thanks to the superhuman nature of our bodies that we survive constant attack. However, humans are becoming increasingly vulnerable to disease. This programme examines the dramatic increase in allergic diseases such as asthma, eczema and hayfever.
They are the miracle pills that shouldn't really work at all. Placebos come in all shapes and sizes, but they contain no active ingredient. Now they are being shown to help treat pain, depression and even alleviate some of the symptoms of Parkinson's disease. Horizon explores why they work, and how we could all benefit from the hidden power of the placebo.
