“This massive collection of neurons is often called ‘the second brain’”The human body’s digestive system, page 22 Chances are that, unless you’ve just had something to eat, the sight of our ‘word burger’ on the front cover of this issue’s How It Works has already triggered the process of digestion in your body. If not, then merely suggesting that it’s a juicy, delicious and savoury lunchtime treat should be making your mouth water and your stomach growl. Just the power that visual and verbal imagery has on your digestive system is amazing, let alone the processes that the smell and taste of your favourite foods activate. In this issue’s cover feature we’re going to take you on a journey through the digestive system, from one end to the, err… other end!…

the face of a tiny monster

This is the head of a pork tapeworm (Taenia solium), a human parasite that can be transmitted through eating pork that hasn’t been cooked properly, or by drinking contaminated water. The adult worm develops from a larva and can live in the small intestine, growing up to three metres in length. This image was taken with a confocal laser microscope. It shows the tapeworm’s two suckers (which look like eyes) and its hook-filled rostellum. This image was taken for the Royal Photographic Society’s Science Photographer of the Year competition.

testing the ‘fat man’ bomb

In this historic photo, bomb assembly group leader Norris Bradbury stands next to the ‘Gadget’. This nuclear bomb was detonated on 16 July 1945 at the Trinity test site in New Mexico, as a trial for the ‘Fat Man’ bomb that would be dropped on the Japanese city of Nagasaki on 9 August 1945. Gadget’s explosion at 5.30am was felt 160 kilometres away and sent a mushroom cloud billowing over 12 kilometres high. Because of the secrecy surrounding the US atomic bomb project a cover story was issued, telling the press that an ammunition store had exploded.…

watching wildfires from space

At a safe distance from the surface, beyond the 100-kilometre-high Kármán line that marks the border between Earth’s atmosphere and space, a NASA satellite snaps this photo of a wildfire blazing over California. These satellites effectively act as extremely tall fire towers that are able to tell firefighters on the ground where new blazes are springing up, and give a broad overview of the extent of the wildfire. The data provided by fire-watching satellites can also help with wildfire forecasting by showing where the driest patches of unburned ground are, and where tall grasses and scrubland could spread fires to forests.…
