Ever wondered how fast our planet is losing its footing? Imagine this: every time you blink, four football fields’ worth of fertile soil vanish into thin air. According to the UN, that’s a mind-boggling 100 million hectares gobbled up by land degradation each year! But when this happens in dry regions, it morphs into something even more sinister: desertification. Karina Lima, a climate ...[Read More]

Fig. 1 The resemblance between bacteria and a hunting wolf might not be obvious, but come take a dive into the weird ecology of Myxobacteria (Collage with photo credit Garcia et al. 2010 and Julien Riedel via pexels.com).

Picture this: bacteria that can slime their way around the soil, finding their prey, circling it, closing in on it and lysing it (or making their cell pop), just to feed on their prey. It sounds like a far stretch from a wolf to a bacteria, but even other soil predators, the comparably huge nematode worms ( up to 100 times bigger!), are afraid of these bacterial “wolves”. I went to the Soil System ...[Read More]

Swamps are spooky. This is the prevailing notion from the depiction of wetlands – the saturated lands of swamps, bogs, and fens – in the media. From the folktales of Will-o’-the-Wisps guiding travellers astray to the many, many swamp monsters of Scooby Doo, the sign is clear: a scrawled “stay away from here” thrust deep in the mud, writ by centuries of storytellers. As a reputation it’ ...[Read More]
