What can I do for a project? How to choose your idea How can I find out more about a topic that I am interested in? How do I start? An Advanced Higher Investigation or an Extended Project will probably be your first chance to try out a real scientific investigation, and to “write your […]

Pollution turns carnivorous plants veggie

Millett J, Foot G.W., Svensson B. (2015) Nitrogen deposition and prey nitrogen uptake control the  nutrition of the carnivorous plant Drosera rotundifolia. Science of The Total Environment, 512, 631-636. doi:10.1016/j.scitotenv.2015.01.067 SUMMARY Carnivorous plants are famous for their ability to capture and digest prey. This is predominantly insects, but can also include birds, rodents and frogs (and humans if you’ve seen […]

Ancient herbs– magic or medicine?

Mix together some leek and garlic in a broth of wine and bullocks gall, and what would you get? It sounds like a rather odd kind of soup, but may in fact be an effective treatment of antibiotic-resistant Stapholococcus aureus, or MRSA. The history of medicine is littered with examples of traditional herbal remedies that […]
