Tropical rainforest, the lungs of our planet, might be releasing more than just CO2!

Tropical rainforest, the lungs of our planet, might be releasing more than just CO2!

When I was thirteen years old, my family and I almost lost our lives due to a carbon monoxide (CO) leak. I never stopped thinking about that incident even though it happened over twenty years ago. Not only because it was a premature realisation of my own mortality, but also because of how sneaky it was: We did not smell it, see it, hear it, or feel it. It was a subtle and slow killer that could ha ...[Read More]

Ocean hypoxia: what does the increase of dead zones mean for marine life?

Ocean hypoxia: what does the increase of dead zones mean for marine life?

When runoff from farmland and urban areas enters our streams and rivers, it carries a heavy load of fertilizers and nutrients. These substances accumulate and flow into our coastal oceans, triggering a series of reactions that can create hypoxic ‘dead zones’. Dead zones are low-oxygen, or hypoxic, areas in the world’s oceans and lakes. Because most organisms need oxygen to live, very f ...[Read More]

Predators or gardeners: how penguins fertilise Antarctica’s biodiversity

Predators or gardeners: how penguins fertilise Antarctica’s biodiversity

On the desolate Antarctic peninsula, a colony of penguins creates a hub of biodiversity. One may ask, how exactly do those aquatic birds help maintain and enrich the variety of different kinds of organisms from plants and animals, to a wide range of insects and micro-organisms that live on our planet? The answer is quite intriguing. Scientists from the University of Science and Technology of China ...[Read More]
