In this 17 minute film on plant and seed propagation, Tholina shares her lifelong knowledge and skills on how to set up an efficient nursery. She tells us about her techniques for seed selection, storage and propagation. And shows us some tricks on taking vegetative cuttings for vegetables, herbs and other hard wood species, as well as the different soil preparations and watering approaches to be considered – all using what we have available to us.

Africa is a continent where borders can get pretty complicated. The main reason for this is the colonial era where European nations divided the continent into spheres of influence by literally drawing the national borders as guided by their interests leaving some countries with peculiar national borders.

That’s why you will find some countries with clearly defined shapes while others not so much. Today we zoom in on some of Africa’s most egregious examples of border weirdness.

Researchers have offered a chemical explanation for sex change in a tropical fish. ↓↓More info and references below↓↓

When a group of the fish loses its dominant male, the biggest female rapidly changes sex, taking on distinctive male coloring and producing mature sperm in as little as 8 days. Although this change is well documented, the molecular mechanisms that drive it have remained unclear. Now, an international group of researchers has offered a chemical explanation for the transformation after analyzing tissue samples from transitioning fish.
