Ethical dilemma: Should we get rid of mosquitoes?

Mosquitoes cause more human fatalities annually than any other animal, yet only a small percentage of the 3,500 mosquito species transmit deadly diseases. Researchers have been experimenting with gene drives, a type of engineered technology, which could potentially eliminate the most dangerous mosquitoes. In this TED Ed video, Talya Hackett explores the question of whether […]

You can envision yourself doing something you’ve never done before – like water […]

Cryopreservation: Can you freeze your body and come back to life? [Science Video]

In 1967, James Bedford had a plan to cheat death. He was the first person to be cryogenically frozen. This process promised to preserve his body until a theoretical future when humanity could cure any illness, and essentially, reverse death. So is it possible to freeze a human, preserve them indefinitely, and then thaw them […]

What is gene editing and how could it shape our future?

Gene editing revolutionised science. PopTika/Shutterstock Gavin Bowen-Metcalf, Anglia Ruskin University It is the most exciting time in genetics since the discovery of DNA in 1953. This is mainly due to scientific breakthroughs including the ability to change DNA through a process called gene editing. The potential for this technology is astonishing – from treating genetic […]
