Chris is here to share more information about sweat then we ever wanted to know. He is also conducting an experiment at Loughborough University, to find out where our bodies sweat the most, and which sweat is the smelliest. First, Chris dons a scientific sweatcollecting vest over a bin bag. Jogging on a treadmill in a heated room, monitored by sweat expert Professor George Havenith, Chris winds up donating two litres of his hardwon drops. The analysis of our drenched doctor is surprising. Now he
Chris volunteers to be a blood donor, so he becomes a leech's lunch! While this bloodsucker is gorging on his arm, our good doctor credits this creature with lifesaving properties. Its saliva is a potent blood thinner, so if a person's fingertip were chopped off, you could reattach it by strategically affixing a leech to get the blood flowing. Chris introduces us to Carl PetersBond, who's a 'leechbreeding king'. He houses 30,000 of the marvellous medical wrigglers, and we get to see a spongelike
We are going on safari through Chris' nose and down his throat to witness what goes on with our voice box when we make a sound. So with a special, tiny, medical camera, the nasendoscope, it's through the nose and past the tongue, look out larynx, here it comes! Xand explains that air forced up your windpipe from the lungs is what makes sound come out. When it passes through the two flaps that comprise your vocal cords, the speed these flaps vibrate at determines whether your voice sounds high or
On the top floor of the Liverpool School of Tropical Medicine, Chris meets Dr Robert Harrison. He and his team make antivenin medicine to save people in Africa who've been bitten by poisonous snakes. Paul Rowley, expert snake handler, is here too, and physically 'milks' a small but deadly snake, the Nigerian sawscaled viper, right in front of Chris. The venom that drips from its fangs will save lives in West Africa, where 36,000 die each year from deadly snake bites. For instance, one bite from

In a meeting with his parents and specialists, the ecstatic lad gets to hear his first words his name spoken by his father!
Nudibranches are some of the most colourful creatures in the sea, but if you were to eat one of them you'd be in a lot of trouble. That's because, as Anne Winters from the University of Queensland explains, these little sea slugs are chockfull of deadly toxins!
Digital images can taken by using a satellite that orbits the earth. The satellite is equipped with a series of mirrors and detectors that take pictures of different strips. Scientist piece them together to show digital images.
Duane talks to drone racer Micah Buedin who gives insight as to why drones crash a lot. Interviewing other racers who competing at this through special, digital headsets that put them 'in the drone' Duane hears about finger jitters, accelerated heartbeats, and dizziness.
To demonstrate our perception of the spoken word, the doctors play a trick on us. What follows is the revelation that when we hear a sound, we tend to read lips. This goes to show the dominance of vision over all the other senses.
Solar energy has its limitations and so far, homes powered by solar can quickly lose power when the sun isn't out. But new tech now means that the sun's energy can be stored in batteries for later use in the home.

With the release of the new five dollar note, we learn about some of the new security measures that have been taken to discourage counterfeiters. We also meet Connor, a young man that successfully petitioned the RBA to add tactile markings to Australia's currency for the blind and vision impaired.
As tectonic plates beneath the Earth's surface continue to shift, over time it has begun to impact the latitude and longitude coordinates of Australia. This video explores how those minor changes will likely lead to much bigger changes over time and how that impacts things like maps as well as modern technology that relies on GPS.
A dog named Mya has been trained as a canine researcher to hunt down koala bear poo an effort for scientists to find them as the cuddly animals are notoriously hard to track down. Once found, researchers study them and work to better understand how to protect their environment.
Dr Alan Pearce and Branden Wilson from Swinburne University and Cocreators have developed a device that monitors sports players and how hard they are hit while on the field to try and reduce the number of concussions in sport.

Doctors Chris and Xand challenge each other to see who can pump fake blood quicker through hoses affixed to two humanshaped wooden cutouts. Chris' 'human' has bits inside the transparent hose network (representing blood vessels), so with the blockages there, he can't get any of the fake blood through.
Omega3 is a type of fat that is essential for our health and is added to many foods and dietary supplements. Most omega3 is sourced from fish and has a fishy smell so how do scientists create versions of omega3 that both smell and taste odour free
