The fermentation of beer

Technology

Tiny yeast-filled robots help brew beer quickly and more efficiently

Millimetre-sized robots made of iron oxide and packed with yeast speed up fermentation of beer by swimming around in the fermenting container and can be removed with a magnet, eliminating the need for filtering out yeast

Searching for the stars near my hometown, Pollachi, led me to the forests of the Anamalai Tiger Reserve. As I moved away from towns and their lights, the darker it got, the more I could see - fireflies, stars. I was fascinated when I saw hundreds of fireflies flashing at the edge of the forest and heard stories of trees laden with fireflies deep in the forest. Predicting the time of their peak activity, I set out to a remote area of the reserve along with forest officials. I waited for nightfall in anxiety. Flashes of green started appearing at twilight. As the place grew dark, millions of fireflies started synchronizing their flashes across several trees. Flashes started in one tree and continued across several trees in a mexican-wave like fashion. It lasted all night. I felt transported to another planet. Being under a sky full of stars, with fireflies flashing in the foreground, owls and other nocturnal creatures calling at a distance, Elephants and Leopards lurking around the corner, this was Nature as our ancestors experienced. The image, created by stacking several photographs, shows a 16 minute activity of the fireflies. ?

'Red matter' superconductor may not be a wonder material after all

A material called red matter, after the colour change it undergoes when subjected to pressure, was hailed as a potential room temperature superconductor, but now other researchers are finding they can't replicate the results
