Just because water covers 70% of the earth’s surface and composes the majority of our bodies doesn’t mean we know everything about it. Marcia Barbosa talks about the many anomalies of water and how exploiting them with nano-tubes could help address the problem of freshwater shortages
Why do we limit ourselves to the labels that are imposed on us? Andrew Nemr analyses the power of labels and the impact they have on us - all while tap dancing
Arthur Zang, a 26-year-old Cameroonian engineer, invented the life-saving Cardiopad. This touch screen medical tablet enables heart examinations such as ECG to be performed in remote locations. The results are transferred wirelessly to specialists so that patients living in rural areas do not have to travel to urban centres for medical examinatio
Most energy storage methods, including batteries, are expensive and difficult to scale. Danielle Fong saw the opportunity to reinvent a classic technology - compressed air - to solve hi-tech energy problems. She developed a method to improve the efficiency of compressed air as an energy storage medium that could radically reduce cost and complexity.
Science could solve many of the existing problems of the world, but there is a gap between research and application. Scientists do not always have the resources needed to link their knowledge with society’s needs. Hayat Sindi creates opportunities for scientists to apply their innovations for social impact.
What does it take to build a nuclear reactor? Jamie Edwards started out on his journey at age 13 to beat Taylor Wilson’s record of being the youngest person to achieve nuclear fusion. He tells of the obstacles he faced as a young schoolboy while trying to achieve his dream, such as trying to convince his headmaster to order deuterium on ebay.
John Mighton is a mathematician and playwright and is the founder of JUMP Math, a charity that is working to improve the teaching math. He appeared in Good Will Hunting, and contributed a monologue to the film based on the argument he makes in his book The End of Ignorance that most people never get a chance to succeed in math because they are not taught according to their true potential
Imagine being able to hold all the material it took to build an airplane in the palm of your hand. Julia Greer combines different design structures at varying nano-scales to create super strong and super light materials. Her research is changing the landscape of materials available today.
Julien Lesgourgues, cosmologist, explores questions like where did the universe come from, what triggered its evolution, does it contain hints of physical laws or species that we are not yet aware of?
The world population is estimated to reach 10 billion in the near future. How can we feed so many with our existing resources? Nina Fedoroff gives an overview of what’s needed, highlighting the important role that science has played in developing food and agriculture throughout human history and the solutions it could offer
Nitin Sawhney performs and talks about the connections between art and science
Robert P. Crease uses laboratory history to examine key issues in philosophy of science, science studies, and ethics. A professor at Stony Brook University, he has written, translated and edited numerous books on the history and philosophy of science.
Sonia Trigueros designs novel nanostructures capable of delivering drugs directly to a targeted area of the human body. This revolutionary technology may be able to treat everything from antibiotic resistant bacteria to cancer.
Twenty percent of the world’s population have no access to electricity. As people’s aspirations for a better quality of life increases, the demand for energy will also rise. Finding efficient resources that can sustain humanity’s needs is a challenge, especially resources that will maintain the balance in the environment and reduce the possibility of climate change. Srikumar Banerjee presents the advantages of thorium as a cleaner and more sustainable energy source
Tamsin Edwards is a particle physicist turned climate scientist trying to find out how uncertain we are about climate change – from the last ice age to future sea level – and how best to communicate this. She is an active blogger and uses social media to change the way people think about climate science.
An inventor of electronic instruments and a DJ, Tim Exile recorded sounds from the data centres of the Large Hadron Collider and mixed them with the sound of the audience at TEDxCERN to create a unique audio track. His performance brought the audience dancing onstage.
More than a million hectares of forest is lost to illegal logging every year in Indonesia alone. Topher White fashioned a simple device made of discarded cell phones and solar panels that detects and alerts to the sound of chainsaws in protected rainforests, allowing intervention in real time.
