GFP – the proteins that allow jellyfish to glow their astonishing luminescent green – changed the way we understand biology. Transferred into plant, bacterial or animal cells, GFP allows them to glow when a blue light is shined on them. But what are the limitations – and where next for ‘reporter proteins’? Professor John Christie, […]

One in eight people, nearly 870 million people, suffer from chronic undernourishment. (United Nations Food and Agriculture Organisation 2011/12 figures). We waste more food in developed countries each year than sub-Saharan Africa produces net in a year/ (The Humanitarian Centre, 2014 Cambridge International Development report) Greedy planet is a podcast about food security. Based at […]
Drew Purves, ecologist and computer scientist, discusses how his research can help us predict climate change, and develop strategies to address it. If you’re afraid of maths and computer programming – don’t be! This video was filmed at the Gatsby Summer School – 6 days of amazing lectures and practical science for undergraduate biology students.
Humans Are Devastating the World’s Forests: Deforestation is devastating the world’s forests. It has reduced the forested area of the earth by almost 80% and shows little sign of slowing down: the damage it has caused is unprecedented, gravely serious and unequivocally caused by humans. Why does this matter? Forests are home to over 200 […]
2050 Will Bring An Extra 2 Billion Hungry Mouths: Between now and 2050, global population levels will increase by 2 billion: it is estimated that food production will have to increase by 70% just to maintain current nutrition levels, which, for many people around the world, are currently far from sufficient. Not only will food […]
The world’s forests could play a major role in feeding our growing population. What’s more, they could improve the health of the world’s poorest – and increase their resilience to extreme events caused by climate change. An EPQ on this topic could investigate issues around health, ecology, and who is responsible for managing the world’s […]
Algae Are One of the Most Diverse Groups of Organisms on the Planet: Algae are the invisible, unsung heroes of the global carbon cycle. Responsible for over half of the carbon dioxide fixed globally, these photosynthetic organisms represent an incredibly diverse group, ranging in size from Prochlorococcus, a single celled alga smaller than most bacteria, to […]
Through a series of chemical reactions, the central spadix of the Titan Arum, Amorphophallus titanium, heats up to emit and distribute an atrocious stench to attract pollinators, thought to be carrion beetles and/or blow flies. This accounts for its common name of ‘corpse flower’. It is native to the rainforests of Sumatra. The film, taken […]
In this full lecture, filmed at the Gatsby Summer School 2015, Prof John Christie shares his research on how plants sense light, and the new field of optogenetics. (View the video on the University of Cambridge website)
Prof Alistair Hetherington, University of Bristol, shares his research on stomata, and explains why fundamental research is important to tackling the world’s biggest problems. This research lecture was recorded at the Gatsby Summer School, 2015. (Watch the video on the Cambridge video site)
Biochemist Professor Sarah O’Connor, from the John Innes Centre, introduces her work to find new molecules that can successfully treat cancer. A 5 minute video recorded at the Gatsby Summer School.
How can you use social media to help your science career (and avoid embarrassing yourself)? Dr Anne Osterrieder, Lecturer in Biology and Science Communication at Oxford Brookes University, shares her 5 top tips. 1) Stay on top of your privacy settings. Do you know who will be able to see what you put online? Use the […]
Professor Ottoline Leyser discusses the different survival strategies of plants and animals – does putting down roots beat running away? And can plants make decisions about what they do?
Dr John Runions, Oxford Brookes University – Growing root tip with dividing cells GFP, or Green Fluorescent Protein, is a protein which, as its name suggests, fluoresces bright green under UV light. First isolated from a species of jellyfish, it has since been used for many different applications. GFP is often used to report the […]
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 […]
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 […]
